About ten years ago, dentists had no interest in the hepatitis B virus infection during their practicing. Recent publications in the medical literature indicate that an increased risk of viral hepatitis infection exists not only for physicians but also dentists. Infection with hepatitis B is a well-recognized occupational hazard among health care professionals. It is diagnosed by detection in the blood of Australia antigen, now called hepatitis B surface antigen (HBsAg). The incubation period is long, between 4 weeks to 6 months and the HBs antigen may be present in the blood for 6 weeks or more before and after the onset of symptoms. But clinical hepatitis is only a small number, probably less than 5 percent ; most all is latent infection. Contact of hands with blood and saliva repeatly expose the practicing dentist to potentially infectious materials. Avoidance of accidental cuts and pricks from instruments and needles is important. The wearing of a mask and spectacles may help, as well as washing hands after work.

Lethal midline granuloma is a T/natural killer cell lymphoma characterized by progressive ulcerationand necrosis of the nasal cavity or pharynx along the midline facial tissues. A case of lethalmidline granuloma in the palate of a 63-year-old woman is reported. The patient had a low-grade fever anda large ulcer with hemorrhage in the palate. Clinically, a malignant tumor was initially suspected becauseof rapid progressive ulceration, but inflammatory disease was pathologically diagnosed on examination ofa tissue specimen stained with hematoxylin and eosin. The definite diagnosis was made by in situ hybridizationwith Epstein-Barr virus RNA (EBV encoded small RNA- 1: EBER 1)-specific oligonucleotideprobes, which showed positive signals in small lymphocytes. The patient's condition became critical becauseof frequent hemorrhage, and she soon died.
