目的：探讨冠桥固定松动牙对重症牙周炎和口腔健康相关生活质量的影响。方法选重症慢性牙周炎患者104例，初诊（T0）时测定牙龈指数（GI）、菌斑指数（PLI），行口腔健康影响程度量表（OHIP－14）和牙周健康自我评价表调查，对患者行牙周洁治和刮治，对松动牙行根管治疗后烤瓷冠桥固定，在固定后1个月（T1）、6个月（T2）及12个月（T3）再次测定GI、PLI及调查OHIP－14和口腔健康自我评价表。结果患者在T1时OHIP－14平均得分（15．6±3．0），与T0时（33．7±3．1）有非常显著性差异（P＜0．01），T2时OHIP－14得分（10．3±2．8），与T1时得分有显著性差异（P＜0．05），T3时得分（7．9±2．5）与T2无显著性差异（P＞0．05）。治疗后各时间点OHIP－14各条目分值及阳性反应患者比率与治疗前比明显降低，牙周健康有关症状所占比率显著降低。治疗后各观测点的GI和PLI与T0比有显著性差异（P＜0．01）。结论冠桥固定对重症牙周炎有显著疗效，可明显改善牙周健康有关症状和口腔健康影响程度，提高口腔健康相关生活质量。

Objective To investigate the impacts of ceramic restoration splinting on severe periodontitis and oral health -related qual-ity of life in Chinese patients .Methods 104 Chinese patients with severe chronic periodontitis were selected to complete a question -naire of 14-item Oral Health Impact Profile (OHIP-14,Chinese version)and an inventory on self evaluation of periodontal health at the following four time points:pre-therapy (T0),1 month (T1)6 months (T2),and 12 months (T3)after the placement of the ceramic res-toration splinting.The patients’gingival index (GI)and plaque index (PLI)were also measured during the four time points .Results Significant differences of average OHIP-14 scores were found between T1 (15.63.0)and T0 (33.73.1)(P 0.01),T2 (10.32.8)and T1 (P<0.01),but not between T3 (7.92.5)and T2 (P>0.05).Compared to T0,the score of each item and the percentage of posi-tive response of the patients in OHIP-14,and the ratio of oral health-related symptoms significantly decreased after therapy ( T1,T2, T3).Meanwhile,there were significant differences in GI and PLI between post-therapy (T1,T2,T3)and T0 (P<0.01).Conclusions Ceramic restoration splinting has significant therapeutic effects on severe periodontitis and can reduce periodontal health -related symptoms and the degree of their impacts on oral health ,thus improving oral health related quality of life .
