Human Immunodeficiency Virus (HIV) infection /Acquired Immunodeficiency Syndrome (HIV/AIDS), earlier considered as a major health problem to cause fatal illness, is today considered to be a chronic manageable condition. The total number of people living with HIV infection globally as of 2014 is approximated at 36.9 million, with the number of new infections being about 2 million, in the same year (UNAIDS). Oral lesions are a feature of HIV infection and their importance in diagnosis, evaluation and prognosis have been reported and confirmed in many studies across the globe. I present the oral manifestations of one of the largest cohort from India and trace the changes following introduction of ART. The purpose of this brief description is to highlight the importance of oral lesions, the trend over a decade and emphasize need for the oral health professionals to identify them, even with the advent of HAART. The cohort comprises of 5055 HIV positive patients from a tertiary referral centre; YRG CARE (Centre for AIDS Research and Education) at Chennai, India, seen over a period of 15 years. The diagnosis of oral lesions was based on the definitive EC-clearing house criteria and confirmation of HIV sero- status for all patients was by ELISA and Western blot. Of 5055 patients data for route of transmission was available for 4938 patients; 93% acquired HIV infection through the heterosexual route of transmission. Male to female ratio was 2.24:1.There was a significant difference (p=0.00) in the mean age among gender (males-36+ 8, females 32+9).There was also a significant difference in the mean CD4 count between males (314+ 239) and females (413+269).86%ofthe study group had at least one oral lesion. Of the HIV related oral lesions OC was seen in 14% of study population. Hyperpigmentation was seen in 18% of the subjects, after ruling out anemia, racial pigmentation and effect of smoking. There was a significant difference in occurrence of the oral lesions between genders. Oral lesions continue to be a feature of HIV infection and their prevalence is decreasing with the advent of HAART. However, emergence of newer entities such as HPV infection and co-morbid conditions such as tuberculosis, ART associated metabolic and adverse reactions need to be studied for their impact on oral health in addition to their systemic effects.
