ABSTRACT
Objective: To screen out adult patients for HBV and HCV infections visiting Khyber College of Dentistry Peshawar [KCD] for different dental treatments and to identify the associated risk factors
Method: This cross-sectional study was conducted at Khyber College of Dentistry, Peshawar in the year 2013. A total of 1540 patients >15 years, visiting KCD for seeking different dental treatments were screened for hepatitis B and C. Informed consent was taken before blood collection and filling of a structured questionnaire. Blood samples were tested against HBsAg and anti HCV by using ICT that were further confirmed by ELISA. The data was analyzed using Epi info version 6
Results: A total of 1540 patients were screened during the study. Among these 36.4% [561] were males and 63.6% [979] were females. Overall prevalence of HBV and HCV was 5.12% [79]. On screening, 2.14% [33] were found to be HBs Ag positive of which 2.5% [14] were males and 1.9% [19] were females. HCV was found positive in 2.98% [46] individuals having male to female ratio of 1.6% and 3.8%. Frequency of HBsAg was high in age group 56-65 year and HCV in 36-45 year group. Previous history of IV/IM injections, spouse patient of hepatitis, blood transfusion, surgical operation were found significant risk factors in the transmission of both hepatitis B and C, while previous history of dental treatment and sharing of clippers were significant risk factor in spreading hepatitis C infection only
Conclusions: Overall prevalence of HCV was higher than HBV. Previous history of injections, spouse patient of hepatitis, blood transfusion, surgical operation were found significant risk factors in the transmission of both hepatitis B and C
