title: Dental caries prevalence in human immunodeficiency virus infected patients receiving highly active anti-retroviral therapy in kermanshah, iran.
abstract: OBJECTIVE
  Introduction of new approaches for the treatment of human immunodeficiency virus (HIV) infection such as anti-retroviral medicines has resulted in an increase in the life expectancy of HIV patient. Evaluating the dental health status as a part of their general health care is needed in order to improve the quality of life in these patients. The aim of this study was to compare the root and crown caries rate in HIV patients receiving highly active antiretroviral therapy (HAART) with that rate in HIV patients without treatment option.
  
  
  METHODS
  This cross sectional study consisting of 100 individuals of both genders with human immunodeficiency virus were divided into two groups: i. group 1 (treatment group) including 50 patients with acquired immunodeficiency syndrome (AIDS) receiving HAART and ii. group 2 (control group) including 50 HIV infected patients not receiving HAART. Dental examinations were done by a dentist under suitable light using periodontal probe. For each participant, numbers of decay (D), missed (M), filled (F), Decayed missed and filled teeth (DMFT), decay surface (Ds), missed surface (Ms), filled surface (Fs), Decayed missed and filled surfaces (DMFS), and tooth and root caries were recorded. Data were analyzed using Chi-square test and independent t test using SPSS 13.0, while p-value of <0.05 was considered statistically significant in all analysis.
  
  
  RESULTS
  The mean and standard deviation (SD) of decayed, missed and filled teeth of those who were on highly active antiretroviral therapy was 6.86 ± 3.57, 6.39 ± 6.06 and 1.89 ± 1.93, respectively. There was no significant difference between these values regarding to the treatment of patients. The mean and standard deviation of DMFT, DMFS and the number of decayed root surfaces were 15.14 ± 6.09, 56.79 ± 28.56, and 4.96 ± 2.89 in patients treated by anti-retroviral medicine which were not significantly different compared to those without this treatment.
  
  
  CONCLUSIONS
  According to the results of the present study, highly active antiretroviral therapy could not be considered as a single factor for dental caries prevalence in HIV-infected patients. However, more research is recommended to evaluate the cariogenic potential of these medicines.
