Determination of Hepatitis B Antibody Titration and Related Factors in Dental Students in Guilan University of Medical Sciences

Abstract

Background and aim: As Hepatitis B is a viral infectious disease that transmits through blood, the purpose of this study was to evaluate the antibody titration against hepatitis B and its related factors in dental students in Guilan University of Medical Sciences in 2017. Materials and methods: This was a descriptive and cross-sectional study. Blood samples were taken from each student and the anti-hepatitis B antibody was titrated. Data were analyzed by SPSS Ver22 software. First, the normal variables were determined by Kolmogorov-Smirnov test. For analysis of variables, T-test, Chi-square and Fisher's exact test were used. In all tests, P Results: The mean age of men and women was 23.71 ± 1.75 and 22.73 ± .086. The anti-hepatitis B antibody titration was more than 100 mIU/ml in 47 samples and in the 21 samples the antibody titration was between 10-100 mIU/ml and in 21 samples the antibody titration was less than mIU/ml 10. There was a significant relationship between the titration of anti-hepatitis B antibody and the gender, the duration of the receiving the vaccine, the number of doses of the vaccine and also with needle stick received. Conclusion: The study showed that, despite the receiving the hepatitis B vaccine, but a relatively high percentage of students did not have an adequate level of immunity.
