Since type B hepatitis is generally regarded as an occupational risk for dentists, the participants at the 1976 annual meeting of the Danish Dental Association were examined for hepatitis B surface antigen (HBsAg) and antibody to HBsAg (anti-HBs). A total of 1,338 dentists (89% of the dentists at the meeting and 29% of all Danish dentists) were included in the study by completion of a questionnaire and by radioimmunoassay of a blood sample for HGsAg and anti-HBs. None of the dentists was HBsAg-positive, but 110 (8.2%) had anti-HBs. An increasing frequency of anti-HBs was found with increasing age, but the figures were similar to the findings in a control population. Evidence is presented that hepatitis found before admittance to or during the time at dental school was predominantly not of type B. In contrast, type B hepatitis predominated during the professional activity of the dentists. On the basis of the serological findings in 29% of all Danish dentists, it is concluded that dentists cannot be regarded as a high-risk group for hepatitis B.
由于乙型肝炎通常被视为牙医的职业风险，因此对参加1976年丹麦牙科协会年会的人员进行了乙型肝炎表面抗原（HBsAg）和抗HBsAg抗体（抗-HBs）检测。通过填写问卷以及对血样进行HBsAg和抗-HBs的放射免疫测定，共有1338名牙医（占参会牙医的89%，占所有丹麦牙医的29%）被纳入研究。没有一位牙医的HBsAg呈阳性，但有110人（8.2%）有抗-HBs。抗-HBs的出现频率随年龄增长而增加，但这些数据与对照组人群的研究结果相似。有证据表明，在进入牙科学校之前或在牙科学校期间发现的肝炎主要不是乙型肝炎。相反，在牙医的职业活动期间，乙型肝炎占主导地位。根据所有丹麦牙医中29%的血清学检测结果，得出结论，牙医不能被视为乙型肝炎的高危人群。
