中国口腔医学各专业实习生对乙型肝炎病毒感染知、信、行情况调查

ObjectiveThis study investigated and compared the knowledge, attitudes, and behaviors(KAB) of Chinese dental interns towards hepatitis B virus(HBV) infection among different departments.MethodsA self-administered questionnaire was surveyed among 232 students who were taking clinical practice. Descriptive statistics and bivariate analyses were used to identify associations between KAB andResultsobtained from different departments and genders. Results Over 80% of participants, independent of affiliated departments, displayed good or excellent level of knowledge. Prosthodontic students have a higher knowledge score compared with students from oral conservative dentistry(P=0.035) and oral maxillofacial surgery(P=0.019 87). Interns from oral conservative dentistry who were exposed to HBV-infected patients have different attitudes(P=0.006), which is also shared by oral maxillofacial surgery(P=0.047). Interns from each department reported that over 60% of them received all three required doses of vaccination or even over three doses, specifically for orthodontic interns, which is around 80%. 34% interns from oral conservative dentistry reported “always” or “mostly” when checking antibody titer status, but 66% of interns from orthodontics said “rarely” or “never”. Orthodontic students had lower injury rate compared with students from oral conservative dentistry(P=0.044), and has a lower trend compared with students of oral maxillofacial surgery(P=0.053). 100% orthodontic interns “always” wear gown. Oral conservative dentistry had higher score than oral maxillofacial surgery(P=2.31e^-6), prosthodontics(P=1.704e^-7) and orthodontics(P=1.3e^-5). Female students have a significantly higher score than male students(P=2.584e^-5).ConclusionMore knowledge about transmission of HBV should be required from prosthodontic interns. Orthodontic interns should hold on high vaccination rates and check antibody titer status more frequently. Interns from oral conservative dentistry should combine theory with practice. Interns from oral maxillofacial surgery should improve self-awareness of their knowledge and maintain positive attitudes.
