接受牙周治療成人病患中牙根分叉侵犯之發生率
Prevalence of Furcation Involvement in Periodontal Treatment Patients
摘要
本研究目的在於（1）評估一中部醫學中心接受牙周治療成人中臼齒根叉侵犯之發生率，（2）分析不同牙位間及同牙位之不同根叉位置間，根叉侵犯發生率的差異。研究樣本為選取50位40至72歲於1995至1999年期間在臺中榮民總醫院牙周病科接受治療病患，以年齡分為三組40-49歲、50-59歲、及60歲以上。檢查牙周探測深度、有無根叉侵犯、及侵犯的嚴重度。統計後發現（1）臼齒中存留率最高為下顎第二大臼齒，最低為下顎第一大臼齒，（2）臼齒中根叉侵犯程度，43.5%無，25.5%第一級，31%第二~三級，（3）根叉侵犯比率由大至小順序為：上顎第一大臼齒、下顎第一大臼齒、上顎第二大臼齒、下顎第二大臼齒，（4）根叉侵犯在上顎臼齒以遠心側較高，下顎則頰、舌兩側比例相當。

The purposes of this study were to evaluate the prevalence of furcation-involved in periodontal patients of a medical center in Taichung, Taiwan and to analysis the prevalence of furcation involvement in different teeth and different furcations of same tooth. The samples of this study were composed 50 patients between 40 and 72 y/o, who received periodontal treatment at periodontal section of dental department of VGHTc. Patients were divided into 3 groups: 40-49, 50-59, and above 60 years old. Periodontal probing depth, degree and severity of furcation involvement were recorded. The results showed that: (1) mandibular second molars had the highest prevalence rate, while mandibular second molars were the lowest (2) 43.5% molars had no furcation involvement, 25% molars were grade I furcation involvement, and 31% molars were grade II-III furcation-involvement. (3) The prevalence of furca-involvement from highest to lowest was upper first molar＞ lower first molar＞ upper second molar＞ lower second molar (4) the prevalence of the distal and buccal furcation involvement of upper first molars were the highest, but the prevalence of buccal and lingual furcation-involvement in lower molars was approximation the same.
