在口腔科领域,人们已对乙型肝炎(HBV)和丁型肝炎病毒给予了足够重视,但对非甲非乙型肝炎(NANBH或丙型肝炎)与口腔科的关系却论述甚少。在西方国家,NANBH可能较乙型肝炎少见,但在某些乙型肝炎高危人群中却较常见;在日本的某些地区,NANBH至少是乙型肝炎的3倍。由于目前多数口腔医务人员均已接种乙肝疫苗,或许也间接获得抗丁肝免疫力,而对NANBH却没有免疫力。因此,NANBH与口腔科的关系越来越密切了。过去对非甲非乙型肝炎的诊断,是排除其它原因引起的肝炎如:药物或甲、乙、丁型肝炎病毒,
In the field of dentistry, enough attention has been paid to hepatitis B (HBV) and hepatitis D virus, but the relationship between non-A, non-B hepatitis (NANBH or Hepatitis C) and stomatology is poorly discussed. In western countries, NANBH may be rarer than hepatitis B but more common in some high-risk groups of hepatitis B; in some parts of Japan NANBH is at least three times more likely than hepatitis B. Since most oral medical staff have already been vaccinated against hepatitis B, they may also indirectly acquire anti-hepatitis B immunity, but have no immunity to NANBH. Therefore, NANBH and dentistry closer and closer. In the past, the diagnosis of non-A, non-B hepatitis was to exclude other causes of hepatitis such as drugs or A, B and D viruses,
