The Effect Of Anti-Retroviral Therapy On The Prevalence Of Oral Manifestation In HIV Sero Positive Patients


Background & Objectives: Acquired immunodeficiency syndrome (AIDS) is a highly lethal, progressively epidemic viral infection characterized by profound impairment of the immune system. According to the Center for Disease Control and Prevention’s (CDC) new classification system, clinical AIDS is defined by a CD4 count of less than 200 (<200) and / or a CD4 percentage of less than 14. The main objective of the current study was to determine the prevalence of oral manifestation of HIV patients on Highly Active Antiretroviral Therapy (HAART) and to compare these with the prevalence of those who were not on (HAART) therapy.
 Methods: Patients were selected from the out patient department of P.M.N.M dental college and hospital Bagalkot and patients from NGOs centers working for HIV/AIDS, Karnataka. A cross sectional was conducted amongst 100 patients diagnosed as HIV sero positive. Information regarding, date of birth, CD4 cell count were obtained from the medical records. Oral examination was done using universal precautions recommended by (CDC). Findings were recorded by using internationally accepted presumptive clinical criteria. Chi-square statistical test were conducted to describe the relationship between the prevalence of Oral manifestation and HAART therapy
Results: The detection of oral manifestation was significantly decreased in subjects on HAART therapy (32%) compared to those who were not on HAART therapy (56%), (P<0.05).
Interpretation & Conclusion:  Compared to non-HAART group, subjects on HAART group had significantly fewer HIV related oral manifestations-probably as a result of an expression of their reconstituted immune system.

Latest About HPV, HIV And Serum Cholesterol

Is HPV - 16 Responsile For Periodontal Breakdown ?
HPV - 16 is associated with a number of oral diseases for e.g. squamous cell carcinoma, condyloma acuminatum, verruca vulgaris, focal epithelial hyperplasia. Earlier it was hypothesised that it has a role in periodontal breakdown as well. A recent case control study by VerĂ´nica V. Horewicz et al.  found that HPV - 16 has no role in periodontal breakdown and periodontal tissues are not the reservoirs of HPV - 16 in the population examined.

Relation Between Mode Of HIV Transmission And Probability Of Oral Lesions
Journal of Oral Pathology and Medicine reports that the mode of HIV transmission is related to the probability of Oral Lesions. Two groups one with heterosexual HIV patients and the other with IV Drug abuser HIV patiens were seleced for the study. The examination revealed that the chances of oral lesions in heterosexual HIV patients is 75% while those in IV Drug Abusers is 46%. Along with this it was also found that candidiasis was the most common lesion affecting the oral cavity of HIV patients.

Serum Cholesterol Level And Oral Carcinoma
Serum cholesterol level is used in various anlysis to predict various diseases. In a study by Vidya K. Lohe published in Journal of Oral Pathology and Medicine it was found that oral carcinoma is associated with low total cholesterol, HDL And LDL, while oral precancers were associated with low total cholesterol and HDL.

Can Commercial Orange Juice Destroy Baby's Teeth ?



Can Commercial Orange Juice Destroy Baby's Teeth ?
With the boom in health care products, many baby heath drinks have been launched in the market. The analysis showed that the pH of these drinks range from 3.5 to 4.0. In an experiment the authors found that 3.77 to 8.10 microns of enamel was destroyed in 1 hr. It is concluded that commercially available baby heath drinks pose a definite risk of excessive enamel erosion on continuous and long term use.

In Vitro Toxic Potential Of Compomers
Three different compomers were tested for their toxicity after applying different types of curing lights.The study concluded that the compomers are potentially toxic to human pulp. Type of light curing unit may also affect the degree of compomers toxicity. These results were obtained by adding compomers to human pulp fibroblast cultures.

Is PALS an Effective Child Management Technique ?
Child management in dental clinics can be done by various methods. PALS stands for passivity to activity through live symbolics. A study conducted on 5-10 year old dental patients showed that PALS is ineffective in modifying a child behaviour and response to interventional dental treatment.

Can Probiotics Bacteria Colonize The Mouth After Taking Such Products ?
Probiotics are in trend these days. Microbiologically probiotics are products fortified with Lactobacilus reuteri ATCC 55730. As documented they colonize the deuodenum and ilium of the subject and provide enhanced immunity. L. reuteri also induces a significantly higher number of CD4positive T-lymphocytes. The L. reuteri dimish in number very soon from the oral cavity and there is no danger of their colonization in the oral habitat.
