Abstract

An epidemiologic examination was carried out to reveal the prevalence of the periodontal diseases and oral pigmentation in patients with Yusho 28 years after PCB exposure. The results obtained were as follows. 1) 162 teeth out of a total of 309 examined teeth had a periodontal pocket deeper than 3 mm, although 32 teeth out of 162 teeth had a periodontal pocket deeper than 4 mm. 2) Oral pigmentation was observed in 47 out of 82 patients with Yusho. It was particularly noteworthy that gingival pigmentation was observed at a much higher frequency in younger patients while pigmentation of the buccal mucosa, the lips or the palate was observed at a much higher frequency in older patients.
