Antibody level and immunity against Hepatitis B virus infection among general dental practitioners

Abstract

Introduction. Immunization against Hepatitis B virus (HBV)is crucial for an effective control in dental healthcare settings. Nevertheless, vaccination rates among general dental practitioners (GDPs)

A cross-sectional study on dental surgeons’ immune status against hepatitis B virus in the Public Health System

“…By analyzing studies performed with dental professionals in other countries, we observed a different situation in comparison with the one identified in this study. In Iran, 11.5% 20 of professionals were not immunized against HBV; in Spain, the estimate was 27.02% 21 ; in Italy, 17% 22 ; in the Netherlands, 12% 23 ; and in the USA, only 7.1% 24 . What may justify this high prevalence of non-vaccination or non-protection among Brazilian dental surgeons is the possibility of a gradual decline of antibody levels, from 13 to 60%, one year after the end of the immunization schedule 21 .…”

Advances in infection epidemiology and control in dental healthcare settings

“…In addition, there are some non-responders who require additional vaccine doses. The aim of the eighth study was to investigate the potential discrepancies between vaccination and immunity among GDPs 27 . The Authors reported that almost 90% GDPs were vaccinated in the last 10 years, but 5% of them were not immune.…”
