determination of hepatitis b antibody titration and related factors in dental students in guilan university of medical sciences

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 at 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 titrated. data analyzed by spss ver22 software. first, the standard variables determined by the kolmogorov-smirnov test. for analysis of variables, the t-test, chi-square, and fisher's exact test used. in all experiments, p <0.05 considered a significant level. 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. 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 receiving the vaccine, the number of doses of the vaccine, and also with needle stick received. conclusion: the study showed that, despite receiving the hepatitis b vaccine, but a relatively high percentage of students did not have an adequate level of immunity.
