A Study on the Types of Distribution of Periodontal Pockets. I. The Distribution of Periodontal Pocket Occurrence.

Mari Kato; Koichi Fukai

歯周疾患の部位差や個体差に対応できるプラークコントロール法の開発を目的として, 歯周ポケットの分布型の解析を試みた。今回は第一報として, 歯周ポケットの部位的特徴を調査した。対象は日本歯科大学新潟歯学部附属病院歯周治療科において歯周炎と診断された58名とし, 歯周ポケットの発現状況を他の臨床的パラメータを含めて詳細に調査した。歯周ポケットの発現状況は平均PDと4mm以上PD出現率から検討した。その結果, 歯周ポケットの発現は頬側より舌側, 歯面別では歯問隣接面, 歯種別では大臼歯部において高かった。この傾向はPlI値でも同様であった。上下歯種別の比較では, 上下顎の発現状況に差を認め, 特に前歯部においてその差が大きく, 下顎前歯部で低かった。一方PlIには上下顎差を認めず, 歯周ポケットの発現の上下顎差にはプラーク以外の因子の関与が考えられた。

The Prognosis after Treatment of Furcation Involvement.

Mari Kato; Koichi Fukai; Misaki Omori; Akira Hasegawa

過去に施行した根分岐部病変の処置に対し, その後の経過を追跡し, 特にプラークコントロールの面からこれらの治療方針の再検討を行った。対象は, 外科的根分岐部病変処置施行症例156例とした。結果は以下のことを示した。1) メインテナンス中の4mm以上ポケットの出現率は全体の8.8%で, 特に分岐部関連部で多かった。2) 処置後, 抜歯の転帰をとったものは156例中7例4.5%で, カリエスが原因のもの4例, 歯周疾患の悪化によるものが3例であった。3) 同様にカリエスの発生は156例中16例10%に認められた。これは処置後2年以内に発生するものが多かった。4) プラークの診査は, PCRとP-PCRを用いた。P-PCRは処置歯のプラーク付着を継続的に評価したものである。抜歯やカリエスの発生はPCRよりこのP-PCRとの関連が大きかった。5) ヘミセクション, 根分割は最終処置として施行されることが多かった。

UNLABELLED The purpose of this study was to assess the methods of establishing of clinically (experimental) healthy gingiva and to evaluate the status of healthy gingiva in Macaca irus. Three monkeys (2 males and 1 female) were used. After preliminary feeding with hard food for 6 months, plaque control procedures (scrubbing method, modified Stillman method, and flossing) were started. Frequency of plaque removal was three times per week under KETALAR (SANKYO, Co. Tokyo), dissociative anesthesia. We also monitored clinical data. RESULTS 1. Forty-nine days later, clinically healthy gingiva were achieved. During this period, no side effects and no tolerance occurred using 12.5 mg/kg of KETALAR, and effective time to perform the procedure was 21.8 minutes. 2. Depending on the plaque control procedure, plaque index (P11), gingival index (GI), and probing depth (PD) were reduced (especially in the first week). However, the level of marginal gingiva (LMG) did not change. 3. Initially and throughout the experiment, PII, GI, PD were lower value in lower jaws, but by the end of experiment there were no differences between the two jaws in PII and PD. However, GI was still lower in the lower jaw at this time. There were no differences between the data for the right and left sides of the jaws at any time throughout the experiment. 4. At the end of experiment, the clinically (experimental) healthy gingiva yielded the following data: PII, 1.7 +/- 0.61; GI, 0.1 +/- 0.60; PD, 1.3 +/- 0.53. No individual differences were found in any of the monkeys at the end of experiment.
