40 patients with periodontitis(P)  ,40 patients with gingivitis (G)and 40 with Healthy gingival tissues (HP) were recruited.  GCF samples from periodontal  sulcus were analyzed using quantitative real-time PCR to detect and quantify HSV virus.
Among the HSV viruses ,EBV prevalence was slightly higher in periodontitis sites compared with controls (33.3% vs. Prevelance of HSV viruses in GCF and its correlation between the clinical parameters  may represent an unspecific indicator for the host response in periodontitis. Although Gram negative bacteria are usually   isolated in the area of periodontal destruction,bacterial etiology is not alone considered in causing destruction as rapid periodontal destruction some times occur in the area of minimal local factors or low level risk factors(3), refractory periodontitis occur after a succesfull periodontal therapy which involves removal of supragingival and subgingival local factors(4) specifity at certain sites(5) varied distribution of disease(6) progression from gingival periodontal disease (7) .so some other factors which play a role in degradation of tissues has to be revealed.
Viruses particularly herpes viruses  and their biology may provide some answers for better understanding of mechanisms involved in the degradation of periodontal tissues.
Thus the etiology of periodontitis is considered complex and multifactorial which involves variety of microorganisms ( bacteria,viruses,fungi ),host factors ,immunological responses.
The aim of this study was to investigate the prevalence of herpes viruses  in gingival crevicular fluid of healthy and diseased periodontium in indianpopulation and to explore whether there is a correlation between the load  of this virus in GCF and the level of periodontal destruction.
The study, approved by the Ethical Committee of the Dr.MGR University and research institute ,. 3) Visible plaque accumulation (PI) measured along the mucosal margin and recorded as present (1) or absent (0). The  PCR procedure was carried out at the Laboratory for Molecular Biology,(hitech laboratories Chennai). Statistical analyses were performed using Statistical Package for the Social Sciences (SPSS) for Windows, version 15.. The difference in mean age was not found neither between the patients with or without HSV-1 nor between genders.
However, within the PG group, several clinical parametersdiffered significantly depending on the presence ofthe virus (Table 3). As previously mentioned, the etiopathogenesis of the periodontal disease is not completely clarified.
Herpes viruses may contribute to the progression of periodontitis through a number of mechanisms. In the multitude of studies dealing with the presence of viruses from the Herpesviridae family in the periodontium,the majority focused on EBV-1 and HCMV [14, 24, 25, 26].
Our results showed a high prevalence of HSV-1 in GCF (35.8%), EBV (25%)HCMV (12%) which is in agreement with some other authors who reported a high prevalence of this virus in specimens taken with paper points  plaque samples of periodontalpockets [8, 9, 27]. The most important result in our study is the relationship between the presence of HSV-1  ,EBV,HCMVand pocket depth. Herpes viruses and in particular HSV-1 are considered to have a potential role in the pathogenesis of some oral diseases.
This model of pathogenesis could be potentially applied to the shifting of gingivitis toward periodontitis. In the present study, we demonstrated that the presence of HSV-1 ,EBV,HCMV in the GCF is related to the degree of tissue destruction in the patients with periodontitis.
Herpes simplex is part of a group of other herpes viruses that include human herpes virus 8 (the cause of Kaposi's sarcoma) and herpes zoster (the virus responsible for shingles and chicken pox). The herpes simplex virus passes moves through bodily fluids (saliva, semen, fluid in the female genital tract) or in fluid from herpes sores. The virus must have direct access to the noninfected person through injuries in their skin or mucus membranes (such as in the mouth or genital area). The virus enters vulnerable cells in the lower layers of skin tissue and tries to reproduce in the cell nuclei. However, if the virus destroys the host cells when it multiplies, inflammation and fluid-filled blisters or ulcers appear.
Eventually, the symptoms return in most cases, causing a new outbreak of blisters and sores. This close-up view of early herpes outbreak shows small, grouped blisters (vesicles) and lots of inflammation (erythema). To infect people, the herpes simplex viruses (both HSV-1 and HSV-2) must get into the body through broken skin or a mucous membrane, such as inside the mouth or on the genital area. Once the virus has contact with the mucous membranes or skin wounds, it begins to replicate.
Sometimes, infected people can transmit the virus and infect other parts of their own bodies (most often the hands, thighs, or buttocks). People with active symptoms of genital herpes are at very high risk for transmitting the infection.
In the past, genital herpes was mostly caused by HSV-2, but HSV-1 genital infection is increasing.
About 40% of men and 70% of women develop other symptoms during initial outbreaks of genital herpes, such as flu-like discomfort, headache, muscle aches, fever, and swollen glands.
On average, people have about four recurrences during the first year, although this varies widely.
Oral herpes (herpes labialis) is most often caused by herpes simplex virus 1 (HSV-1) but can also be caused by herpes simplex virus 1 (HSV-2). The blisters eventually rupture as painful open sores, develop a yellowish membrane before healing, and disappear within 3 - 14 days. Rarely, the infection may be accompanied by difficulty in swallowing, chills, muscle pain, or hearing loss.
It is not completely known what triggers renewed infection, but several different factors may be involved. Although the prevalence of genital herpes is declining in the United States, it still remains in epidemic proportions. Risk factors for genital herpes include a history of a prior sexually transmitted disease, early age for first sexual intercourse, a high number of sexual partners, and poor socioeconomic status. People with compromised immune systems, notably patients with HIV, are at very high risk for HSV-2. The following are examples of people who are at particularly risk for specific forms of herpes. Wrestlers, rugby players, and other athletes who participate in direct contact sports without protective clothing.
Genital herpes is contagious from the first signs of tingling and burning (prodrome) until the time that sores have completely healed. To reduce the risk of passing the herpes virus to another part of your body (such as the eyes and fingers), avoid touching a herpes blister or sore during an outbreak. Recent studies have suggested that male circumcision may help reduce the risk of HSV-2, as well as human papillomavirus (HPV) and HIV infections.
Pregnant women who are infected with either herpes simplex virus 2 (HSV-2) or herpes simplex virus 1 (HSV-1) genital herpes have a higher risk for miscarriage, premature labor, retarded fetal growth, or transmission of the herpes infection to the infant while in the uterus or at the time of delivery..
During a first infection, the virus is shed for longer periods, and more viral particles are excreted.
An infection that first occurs in the late term does not allow the mother to develop antibodies that would help her baby fight off the infection at the time of delivery.
The risk for transmission also increases if infants with infected mothers are born prematurely, if there is invasive monitoring, or if instruments are required during vaginal delivery. Very rarely, the virus is transmitted across the placenta, a form of the infection known as congenital herpes. Infants may acquire congenital herpes from a mother with an active herpes infection at the time of birth.
Unfortunately, only 5% of infected pregnant women have a history of symptoms, so in many cases herpes infection is not suspected, or symptoms are missed, at the time of delivery. Obtaining routine herpes cultures on all women during the prenatal period is not recommended. Performing chorionic vilus sampling, amniocentesis, and percutaneous fetal blood draws can safely be performed during pregnancy.
If lesions in the genital area are present at the time of birth, Cesarean section is usually recommended. If lesions erupt shortly before the baby is due then samples must be taken and sent to the laboratory. Some doctors recommend anti-viral medication for pregnant women who are infected with HSV-2. Herpes infection in a newborn can cause a range of symptoms, including skin rash, fevers, mouth sores, and eye infections. Herpes meningitis, an inflammation of the membranes that line the brain and spinal cord, occurs in up to 10% of cases of primary genital HSV-2. Iridocyclitis is another serious complication of ocular herpes, in which the iris and the area around it become inflamed. Herpes simplex is particularly devastating when it occurs in immunocompromised patients and, unfortunately, coinfection is common. The majority of patients with HIV are co-infected with HSV-2 and are particularly vulnerable to its complications.
According to the CDC, up to 50% of first-episode cases of genital herpes are now caused by herpes simplex virus 1 (HSV-1). Viral culture tests are made by taking a fluid sample, or culture, from the lesions as early as possible, ideally within the first 3 days of appearance. Polymerase chain reaction (PCR) tests are much more accurate than viral cultures, and the CDC recommends this test for detecting herpes in spinal fluid when diagnosing herpes encephalitis (see below). An older type of virologic testing, the Tzanck smear test, uses scrapings from herpes lesions. Serologic (blood) tests can identify antibodies that are specific to the virus and its type, herpes virus simplex 1 (HSV-1) or herpes virus simplex 2 (HSV-2). Although glycoprotein (gG) type-specific tests have been available since 1999, many of the older nontype-specific tests are still on the market. Serologic tests are most accurate when administered 12 - 16 weeks after exposure to the virus. False-negative (testing negative when herpes infection is actually present) results can occur if tests are done in the early stages of infection. At this time, doctors do not recommend screening for HSV-1 or HSV-2 in the general population.
Brain biopsy is the most reliable method of diagnosing herpes encephalitis, but it is also the most invasive and is generally performed only if the diagnosis is uncertain. The polymerase chain reaction (PCR) assay of cerebrospinal fluid looks for tiny pieces of the DNA of the virus, and then replicates them millions of times until the virus is detectable. Other conditions that may be confused with oral herpes include herpangina (a form of the Coxsackie A virus), sore throat caused by strep or other bacteria, and infectious mononucleosis. Conditions that may be confused with genital herpes include bacterial and yeast infections, genital warts, herpes zoster (shingles), molluscum (a virus disease which produces small rounded swellings), scabies, syphilis, and certain cancers. In a few cases, HSV-2 may occur without lesions and resemble cystitis and urinary tract infections. Simple corneal scratches can cause the same pain as herpetic infection, but these usually resolve within 24 hours and don't exhibit the corneal lesions characteristic of herpes simplex. Skin disorders that may mimic herpes simplex include shingles and chicken pox (both caused by varicella-zoster, another herpes virus), impetigo, and Stevens-Johnson syndrome, a serious inflammatory disease usually caused by a drug allergy. Antiviral drugs called nucleosides or nucleotide analogues are the main drugs used to treat genital herpes. The drugs are used initially to treat a first attack of herpes, and then afterward to either suppress the virus or treat recurrent outbreaks. To treat outbreaks, drug regimens depend on whether it is the first episode or a recurrence and on the medication and dosage prescribed.
Because the frequency of herpes recurrences often diminishes over time, patients should discuss annually with their doctors whether they should stay with drug therapy or discontinue it.
Acyclovir (Zovirax), valacyclovir (Valtrex), and famciclovir (Famvir) -- the anti-viral pills used to treat genital herpes -- can also treat the cold sores associated with oral herpes. Penciclovir (Denavir) heals herpes simplex virus 1 (HSV-1) sores on average about half a day faster than without treatment, stops viral shedding, and reduces the duration of pain. Acyclovir cream (Zovirax) works best when applied early on (at the first sign of pain or tingling). Docosanol cream (Abreva) is the only FDA-approved non-prescription ointment for oral herpes.
Some people report that drying the genital area with a blow dryer on the cool setting offers relief. Avoid tight-fitting clothing, which restricts air circulation and slows healing of the sores.

Local application of ice packs may alleviate the pain and help reduce recurrences by suppressing the virus.
Wearing sun block helps prevent sun-triggered recurrence of herpes simplex virus 1 (HSV-1). Avoid sex during both outbreaks and prodromes (the early symptoms of herpes), when signs include tingling, itching, or tenderness in the infected areas. Over-the-counter medications such as aspirin, acetaminophen (Tylenol), or ibuprofen (Advil, Motrin), can be used to reduce fever and local tenderness. Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Many herbal and dietary supplement products claim to help fight herpes infection by boosting the immune system.

Estimation of Load of Herpes Viruses in GCF and its Impact on Clinical Parameters in Periodontitis. As Herpes viruses  are detected in diseased sites and in gingival crevicular fluid in mild (8) and severe (9) and aggressive [10] periodontitis as well as in the periodontium of HIV patients [11] and patients with the followingsyndromes: Papillon-Lefevre [12], Down [13] and Kostmann [14]. The group of patients with periodontitis (periodontitis group -PG) consisted of 40 patients (20 men and 20 women, age 23-76) who had clinical signs of periodontitis and were treated at the department  for Periodontology and. For the evaluation of intra- and inter- reliability, 10% of randomly selectedsubjects were re-examined 2 weeks after the first examination. Probing pocket depth and clinical attachment loss revealed higher values in the patients with HSV, while plaque index was lower in the HSV positive group than in the HSV-1 negative group.
The initial event in the development of periodontitis is the formation of dental biofilm followed by gingivitis. It is assumed that these viruses are able to express cytopathogenic effects, immune evasion, immunopathogenicity, latency, reactivation and tissue tropism [23]. Although,the subjects with a healthy periodontium were much younger than those with periodontitis, this discrepancy should not have an impact on our results as the peak of the primary herpetic infection occurs until the age of five [29].However, we can assume that periodontal disease did not evelop in younger individuals, or did not lead to clinically noticeable tissue destruction yet.
Our results showed a significantly higher prevalence of HSV-1 in deeper pockets than in shallower ones; clinical parameters (CAL, PPD) also showed significantly higher values in HSV+ periodontitis patients than in HSV-, which is in agreement with the results of Slots et al.
There is evidence of a higher presence of HCMV, EBV-1 and HSV in Nigerian malnourished children with acute necrotizing ulcerative gingivitis (ANUG) [34]. The confirmation of the role of HSV-1,EBV,CMV  in the pathogenesis of periodontitis will require a larger sample along with a prospective study that would detect the presence of HSV in the periodontium before the onset, at the time of periodontitisinitiation, and periodically during its development.

Type-specific herpes simplex virus-1 and herpes simplex virus-2 seroprevalence in Romania: comparison of prevalence andrisk factors in women and men. Cytomegalovirus and Epstein-Barr virus are associated with symptomatic periapical pathosis. BackgroundHerpes simplex virus (HSV) commonly causes infections of the skin and mucous membranes. Each virus can be carried in bodily fluids (saliva, semen, fluid in the female genital tract) or in fluid from herpes sores. This process, known as autoinoculation, is uncommon, since people generally develop antibodies that protect against this problem. Genital herpes is most often transmitted through sexual activity, and people with multiple sexual partners are at high risk. Unfortunately, evidence suggests about a third of all herpes simplex virus 2 (HSV-2) infections occur when the virus is shedding but producing no symptoms. For patients with symptoms, the first outbreak usually occurs in or around the genital area 1 - 2 weeks after sexual exposure to the virus. It usually affects the lips and, in some primary attacks, the mucous membranes in the mouth.
If the primary (initial) oral infection causes symptoms, they can be very painful, particularly in small children. In adolescents, the primary infection is more apt to appear in the upper part of the throat and cause soreness. The outbreak of infection is often preceded by a prodrome, an early group of symptoms that may include itching skin, pain, or an abnormal tingling sensation at the site of infection. Recurrent outbreaks of herpes simplex virus (HSV) feature most of the same symptoms at the same sites as the primary attack, but they tend to be milder and briefer. These include sunlight, wind, fever, physical injury, surgery, menstruation, suppression of the immune system, and emotional stress.
For most people, outbreaks recur with more frequency during the first year after an initial attack. Women are more susceptible to HSV-2 infection because herpes is more easily transmitted from men to women than from women to men.
This group is at higher than average risk for herpetic whitlow, herpes that occurs in the fingers. These individuals are at risk for herpes gladiatorum, an unusual form of HSV-1 that is spread by skin contact with exposed herpes sores and usually affects the head or eyes.
It is almost impossible to defend against the transmission of oral herpes since it can be transmitted by very casual contact. While condoms may not provide 100% protection, they have been proven to significantly reduce the risk of sexual disease transmission.
Lubricants can help prevent friction during sex, which can irritate the skin and increase the risk for outbreaks.
While the chances of transmitting or contracting herpes from a toilet seat or towel are extremely low, it is advisable to wipe off toilet seats and not to share damp towels. Although about 25 - 30% of pregnant women have genital herpes, less than 0.1% of babies are born with neonatal herpes. Transmission can occur if the amniotic membrane of an infected woman ruptures prematurely, or as the infant passes through an infected birth canal.
Also rarely, newborns may contract herpes during the first weeks of life from being kissed by someone with a herpes cold sore.
Aggressive treatment with antiviral medication is required, but may not help systemic herpes. If there is evidence of an active outbreak, doctors usually advise a Cesarean section to prevent the baby contacting the virus in the birth canal during delivery. Samples are cultured to detect the virus at 3 - 5-day intervals prior to delivery to determine whether viral shedding is occurring.
Recent studies indicate that acyclovir (Zovirax) or valacyclovir (Valtrex) or famciclovir (Famvir)Valtrex can help reduce the recurrence of genital herpes and the need for Cesarean sections. It is important to treat babies quickly, before the infection spreads to the brain and other organs. In most cases, ocular herpes causes inflammation and sores on the lids or outside of the cornea that go away in a few days. In children, this is often caused by thumbsucking or finger sucking while they have a cold sore. DiagnosisThe herpes simplex virus is usually identifiable by its characteristic lesion: A thin-walled blister on an inflamed base of skin.
Centers for Disease Control (CDC) recommends that both virologic and serologic tests be used for diagnosing genital herpes. However, recurrences of genital herpes, and viral shedding without overt symptoms, are much less frequent with HSV-1 infection than herpes simplex virus 2 (HSV-2). The viruses, if present, will reproduce in this fluid sample but may take 1 - 10 days to do so. PCR can make many copies of the virus’ DNA so that even small amounts of DNA in the sample can be detected. When the herpes virus infects someone, their body’s immune system produces specific antibodies to fight off the infection. False-positive results (testing positive when herpes infection is not actually present) can also occur, although more rarely than false-negative.
Computed tomography or magnetic resonance imaging scans may be used to differentiate encephalitis from other conditions. Canker sores frequently crop up singly or in groups on the inside of the mouth or on or under the tongue.
It is most common in infants but can appear in people of all ages, particularly people taking antibiotics or those with impaired immune systems.
Studies suggest that daily drug therapy is safe and effective for up to 6 years with acyclovir, and up to 1 year with valacyclovir or famciclovir. Although there is some evidence these drugs may reduce shedding, they probably do not prevent it entirely. As with antibiotics, doctors are concerned about signs of increasing viral resistance to acyclovir and similar drugs, particularly in immunocompromised patients (such as those with AIDS). National Institutes of Health has been conducting the Herpevac Trial for Women to investigate a vaccine for preventing herpes in women who are not infected with HSV-1 or HSV-2. Ideally, the patient should apply the cream within the first hour of symptoms, although the medication can still help if applied later. The patient applies the cream five times a day, beginning at the first sign of tingling or pain. They include Anbesol gel, Blistex lip ointment, Camphophenique, Herpecin-L, Viractin, and Zilactin. Home RemediesPatients can manage most herpes simplex infections that develop on the skin at home with over-the-counter painkillers and measures to relieve symptoms. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There has been little research on these products, and little evidence to show that they really work.
Human herpes simplex virus infections: epidemiology, pathogenesis, symptomatology, diagnosis, and management.
Third trimester antiviral prophylaxis for preventing maternal genital herpes simplex virus (HSV) recurrences and neonatal infection.
A meta-analysis to assess the efficacy of oral antiviral treatment to prevent genital herpes outbreaks. A licensed medical professional should be consulted for diagnosis and treatment of any and all medical conditions.
Healthy control group (HC) consisted of 40 volunteers(20 men and 20women, age 18-33) without clinical signs of periodontitis. Radiographs were taken from all the diseased sites using a paralleling technique combined with long cone. Gcf was collected in small plastic tubes samples were stored at-70°C until further analysis. First, the total viral  DNA was isolated using reagents according to the manufacturer’s guidelines**.
Statisticaldifferences between frequencies were tested with Chi-square test with Yates’ correction.
In addition, HSV occurred more often in deeper pockets (Table 4),and three out of four deepest pockets measuring 11 mm harbored HSV1. They can infect or alter structural cells and host defense cells in the periodontium, and thereby reduce the ability of periodontal tissuesto resist bacterial insults [22].
Consequently, it would be valuable to conduct a follow-up of young patients with HSV-1 detected in their periodontium and periodically make clinical examinations.As for the different number of male and female individuals in the healthy control group, gender itself is not considered as the predilection factor for periodontal destruction[30]. Parra and Slots [9] also found statistically higher prevalence of HSV-1 in patients with chronic periodontitis than in patients with mild gingivitis.

The hypothesis is that herpes viruses can affect the host’s immune system, facilitating the development of secondary bacterial infections.
Also, future studies demonstrating the role of HSV infection in the pathogenesis of periodontitis should prove that eradication of viral infection can prevent the progression of periodontal destruction. They differ in many ways, but the viruses share certain characteristics, notably the word "herpes," which is derived from a Greek word meaning "to creep." This refers to the unique characteristic pattern of all herpes viruses to "creep along" local nerve pathways to the nerve clusters at the end, where they remain in an inactive state for some indeterminate time. Until recently, the general rule was to assume that HSV-1 infections occur in the oral cavity (mouth) and are not sexually transmitted, while HSV-2 attacks the genital area and is sexually transmitted. The risk for infection is highest with direct contact of blisters or sores during an outbreak. HSV-1 is the most prevalent form of herpes simplex virus, and infection is most likely to occur during preschool years.
The first signs are a tingling sensation in the affected areas (such as genitalia, buttocks, and thighs) and groups of small red bumps that develop into blisters. The virus sheds for a much shorter period of time (about 3 days) compared to in an initial outbreak of 3 weeks. There are some differences in frequency of recurrence depending on whether HSV-2 or HSV-1 causes genital herpes.
A herpes infection may occur on the cheeks or in the nose, but facial herpes is very uncommon. Oral herpes can be provoked within about 3 days of intense dental work, particularly root canal or tooth extraction. During that period, the body mounts an immune response to HSV, and in most healthy people recurring infections tend to become progressively less severe and less frequent. The incidence in children varies among regions and countries, with the highest rates occurring in crowded and unsanitary regions. Centers for Disease Control and Prevention, at least 45 million Americans age 12 and over, about 1 in 5 teenagers and adults, are infected with HSV-2. Other immunocompromised patients include those taking drugs that suppress the immune system and transplant patients. However, herpes can also be transmitted when symptoms are not present (asymptomatic shedding). Only water-based lubricants (such as K-Y Jelly, Astroglide, AquaLube, and glycerin) should be used. The baby is at greatest risk from an asymptomatic infection during a vaginal delivery in women who acquired the virus for the first time late in the pregnancy.
This increased risk is present if the woman is having or has recently had an active herpes outbreak in the genital area.
If no lesions are present and cultures indicate no viral shedding, a vaginal delivery can be performed and the newborn is examined and cultured after delivery. Women begin to take the drug on a daily basis beginning in the 36th week of pregnancy (last trimester).
Neonatal herpes can spread to the brain and central nervous system causing encephalitis and meningitis and leading to mental retardation, cerebral palsy, and death. Scarring and corneal thinning develop, which may cause the eye's globe to rupture, resulting in blindness.
It can also occur in adult health care workers, such as dentists, because of increased exposure to the herpes virus. HSV-2 infection increases HIV levels in the genital tract, which makes it easier for the HIV virus to be spread to sexual partners. However, other conditions can resemble herpes, and doctors cannot base a herpes diagnosis on visual inspection alone.
Patients diagnosed with genital herpes should also be tested for other sexually transmitted diseases. It is important for doctors to determine whether the genital herpes infection is caused by HSV-1 or HSV-2, as the type of herpes infection influences prognosis and treatment recommendations.
If infection is severe, testing technology can shorten this period to 24 hours, but speeding up the timeframe during this test may make the results even less accurate. PCR is much more expensive than viral cultures and is not FDA-approved for testing genital specimens. Findings of specific giant cells with many nuclei or distinctive particles that carry the virus (called inclusion bodies) indicate herpes infection. If a blood test detects antibodies to herpes, it’s evidence that you have been infected with the virus, even if the virus is in a non-active (dormant) state. Its major advantages are that it requires only a finger prick and results are provided in less than 10 minutes. It is costly and time consuming, however, and is not as widely available as the other tests.
PCR identifies HSV in cerebrospinal fluid and gives a rapid diagnosis of herpes encephalitis in most cases, eliminating the need for biopsies. This ulcer is seen in an individual with AIDS and is located in front and just below the bottom teeth. The infection may recur after treatment has been stopped and, even during therapy, a patient can still transmit the virus to another person. It is generally recommended for patients who have frequent recurrences (6 or more outbreaks per year). The use of condoms during asymptomatic periods is still essential, even when patients are taking these medications.
The drug is continued for 4 consecutive days, and should be reapplied every 2 hours while awake. There have been several reported cases of serious and even lethal side effects from herbal products. Then, real-time PCR was carried out for HSV using the Herpesvirus quantitative Real Time PCR kit†† and a thermal cycling system‡‡.
We also tried to establish acorrelation between the presence of HSV-1 ,EBV,HCMV and the recurrence of oral herpes infections.
Reactivation of herpes viruses can decrease the local host resistance and lead to the overgrowthof periodontal pathogenic bacteria, as Porphyromonas gingivalis[7].
On the other hand, lactation, pregnancy,oral contraceptives, menstrual period may have an impact on periodontal tissues, which  is why we excluded females with any of the mentioned conditions. Other authors did not find correlation between the depth of periodontal pockets and HSV-1,EBV,HCMV presence. HSV is one of the most difficult viruses to control and has plagued mankind for thousands of years.
It is now widely accepted, however, that either type can be found in either area and at other sites. The prodrome, which may last as short as 2 hours or as long as 2 days, stops when the blisters develop. Occasionally, the symptoms may not resemble those of the primary episode but appear as fissures and scrapes in the skin or as general inflammation around the affected area.
Studies suggest that by age 5 more than a third of children in low-income areas are infected compared to 20% of children in middle-income areas.
While HSV-2 remains the main cause of genital herpes, in recent years the percentage of cases of genital herpes caused by HSV-1 has significantly increased because of of oral-genital sex.
Natural condoms made from animal skin do NOT protect against HSV infection because herpes viruses can pass through them. Oil-based lubricants (such as petroleum jelly, body lotions, and cooking oil) can weaken latex.
Possible ComplicationsThe severity of symptoms depends on where and how the virus enters the body.
Fortunately, rapid diagnostic tests and treatment with acyclovir have both significantly improved survival rates and reduced complication rates. Fortunately, herpes meningitis usually resolves without complications, lasting for up to a week, although recurrences have been reported. Viral cultures are very accurate if lesions are still in the clear blister stage, but they do not work as well for older ulcerated sores, recurrent lesions, or latency. The presence of antibodies to herpes also indicates that you are a carrier of the virus and might transmit it to others. For a recurrent episode, treatment takes 1 - 5 days depending on the type of medication and dosage.
Valacyclovir may work especially well for preventing herpes transmission among heterosexual patients when one partner has herpes simplex virus 2 (HSV-2) and the other partner does not. However, patients who do not respond to standard regimens should be monitored for emergence of drug resistance. Links to other sites are provided for information only -- they do not constitute endorsements of those other sites. Briefly, quantitative real-time PCR assays were performed in a volume of 25 Wl composed of 12,5 Wl of DNA mastermix 2,5Wl of primers***(FAM, emission 520nm), 2,5 Wl of internal control DNA†††, 2,5 Wl of internal control primers & double-dye probe (Yellow Dye, emission 548 nm)‡‡‡and 5 Wl of DNA extract or EBV positive control or EBV negative control or DNAStandard (for quantitative standard curve)§§§. Regarding the influence of gender on HSV-1 prevalence, no gender differences were found in the study performed in Romania from 2004-2005 [31]. In fact, HSV-1 is now responsible for up to half of all new cases of genital herpes in developed countries.
However, by the time Americans of all economic backgrounds reach age 60, about 60 - 85% have become infected with HSV-1. Except for people in monogamous relationships with uninfected partners, everyone who is sexually active is at risk for genital herpes. Nonoxynol-9 can cause irritation around the genital areas, which makes it easier for herpes and other STDs to be transmitted.
Except in very rare instances and in special circumstances, the disease is not life threatening, although it can be very debilitating and cause great emotional distress. Recurring herpes and a first infection that is acquired early in the pregnancy pose a much lower risk to the infant. For those who recover, nearly all suffer some impairment, ranging from very mild neurological changes to paralysis. At these stages the virus may not be active enough to reproduce sufficiently to produce a visible culture.
However, valacyclovir may not be as effective as acyclovir or famiciclovir for patients who have very frequent recurrences of herpes (more than 10 outbreaks per year).
For the rest of them, 14 patients noted at least one episode of herpes labialis, and 36 denied it.
As the prevalence of HSV-1 infection varies among different geographic regions, and Romania borders with Serbia, we consider findings of this study relevant in regard to our population.Contreras and Slots [27] also failed to detect differences in the presence of HSV-1 between PG and HC groups.
Our results also showed lower values for the plaque index in PG HSV+ patients, which speaks in favor of HSV-1 influence on periodontaltissue destruction and confirms the hypothesis that viruses might have influence on periodontitis progression in patients with good oral hygiene [3].
They presume that viral infections contribute to immune impairment, which in turn creates afertile ground for endodontopathogenic bacterial infections. In fact, studies indicate that 10 - 25% of people infected with HSV-2 are unaware that they have genital herpes.
The best chances for a favorable outcome occur in patients who are treated with acyclovir within 2 days of becoming ill.
The Tzanck test is not reliable for providing a conclusive diagnosis of herpes infection and is not recommended by the CDC. Any duplication or distribution of the information contained herein is strictly prohibited. Kamma et al.[33] detected significantly higher frequencies of HCMV, EBV-1 and HSV in active and progressive periodontitis sites than in stable sites. In addition, because herpes simplex virus 1 can be passed in saliva, people should also avoid sharing toothbrushes or eating utensils with an infected person.
