RESUMO
An epidemiologic examination was carried out to reveal the prevalence of the periodontal diseases and oral pigmentation in patients with Yusho in 2010. The results obtained were as follows. 1) Yusho patients complained of tooth pain and periodontal diseases such as gingival swelling, but not of oral pigmentation. 2) 104 patients out of 117 patients with Yusho, who were measured periodontal pocket depth according to Ramfjord' methods, had at least one tooth with periodontal pocket deeper than 3 mm. Similarly, 314 teeth out of a total 551 examined teeth showed a periodontal pocket with more than 3 mm in depth. However, it was determined that 57 teeth had a periodontal pocket deeper than 4 mm. 3) Oral pigmentation was observed in 63 patients out of 122 patients with Yusho. In this study, gingival pigmentation was most predominant among oral pigmentation. The prevalence of oral pigmentation in male patients seemed to be somewhat higher than that in female patients. In addition, the prevalence of oral pigmentation tended to be higher in patients under seventy years old than patients beyond the age of seventy. These results indicated that PCB-related compounds may be responsible for the higher prevalence of both periodontal diseases and oral pigmentation.

An epidemiologic examination was carried out to reveal the prevalence of the periodontal diseases and oral pigmentation in patients with Yusho in 2008. The results obtained were as follows. 1) Yusho patients complained of tooth pain and periodontal diseases such as gingival swelling, gingival bleeding, but not of oral pigmentation. 2) 116 patients out of 148 patients with Yusho, who were measured periodontal pocket depth according to Ramfjord' methods, had at least one tooth with periodontal pocket deeper than 3 mm. Similarly, 399 teeth out of a total 710 examined teeth showed a periodontal pocket with more than 3 mm in depth. However, it was determined that 74 teeth had a periodontal pocket deeper than 4 mm. 3) Oral pigmentation was observed in 91 patients out of 155 patients with Yusho. In this study, gingival pigmentation was most predominant among oral pigmentation. The prevalence of oral pigmentation in male patients seemed to be somewhat higher than that in female patients. In addition, the prevalence of oral pigmentation tended to be higher in younger patients than in elder patients. Pigmentation of the buccal mucosa, lip or palate, however, was observed only in patients beyond the age of fifty. These results indicated that PCB-related compounds may be responsible for the higher prevalence of both periodontal diseases and oral pigmentation.

An epidemiologic examination was carried out to reveal the prevalence of the periodontal diseases and oral pigmentation in patients with Yusho in 2006. The results obtained were as follows. (1) 98 patients out of 106 patients with Yusho, who were measured periodontal pocket depth according to Ramfjord' methods, had at least one tooth with periodontal pocket deeper than 3 mm. Similarly, 343 teeth out of a total 494 examined teeth showed periodontal pocket with more than 3 mm depth. (2) Oral pigmentation was observed in 61 patients out of 116 patients with Yusho. In this study, gingival pigmentation was most predominant among oral pigmentation. The prevalence of oral pigmentation in male patients seemed to be somewhat higher than that in female patients. In addition, this examination revealed that the patients below the age of sixty had a high prevalence of oral pigmentation. These results indicated that PCB-related compounds may be responsible for the higher prevalence of both periodontal diseases and oral pigmentation.

An epidemiologic examination was carried out to reveal the prevalence of the periodontal diseases and oral pigmentation in patients with Yusho. The results obtained were as follows. 1) 95 patients out of 110 patients, who were examined periodontal pocket depth using Ramfjord' methods, had at least one tooth with periodontal pocket deeper than 3 mm. Similarly, 276 teeth out of a total 495 examined teeth showed periodontal pockets with more than 3 mm depth. However, the ratio of the teeth with periodontal pockets deeper than 4 mm to total examined teeth in each age fell to less than 25%. 2) Oral pigmentation was observed in 75 patients out of 121 patients with Yusho. In this examination, gingival pigmentation was most predominant among oral pigmentation. It is of particular interest that severe pigmentation tended to be observed at a much higher frequency in younger patients with Yusho. Taken these findings into consideration, it was suggested that PCBs and related compounds might play an important role in the development of both periodontal diseases and oral pigmentation.
