摘要
目的:探讨慢性牙周炎及其引起的牙髓根尖周病变治疗方法。方法:将118位病人的166个患牙进行牙髓活力测试、评价。根据临床症状进行牙周基础治疗和根管治疗术,随访6个月,观察疗效。结果:前磨牙冷诊阳性率77.55%,电活力阳性率85.71%,开髓后发现有67.34%牙髓部分或全部坏死;磨牙冷诊阳性率75.22%,电活力阳性率72.57%,开髓后发现有56.63%牙髓部分或全部坏死。根管治疗术6个月后复查所有患牙症状明显改善,咬合功能基本恢复正常,松动度、探诊深度都有明显改善(P<0.05)。结论:牙髓状态应根据病史和症状进行综合判断。慢性牙周炎引起的牙髓刺激症状经过牙周基础治疗以及脱敏或楔形缺损充填治疗症状明显减轻者,可不做牙髓处理。经上述治疗后症状仍未消失,应行根管治疗术。如有牙髓坏死,并由此加重骨破坏者,应尽早进行根管治疗术。
AIM： To investigate the treatment of periodontic - endodontic lesion induced by periodontitis. METHODS ：166 teeth of 118 patients were evaluated by pulp vitality test. Periodontal initial therapy and root canal therapy were performed according to their symptoms. All cases were followed up for 6 months after finished treatment. RESULTS ：The positive ratio of cold test of premolars was 77.55% and 75.22% of molar. The positive ratio of electric pulp testing of premolars was 85.71 and 72.57 of molars. All symptoms were improved after 6 months and occlusion function was rehabilitated . Tooth mobility and depth of pocket were reduced significantly. （ P 〈 0.01 ）. CON- CLUSION：Pulp condition should be judged according to both history and symptoms and clinical test. Pulp treatment was not needed if symptoms disappeared after periodontal initial therapy and desensitization and filling therapy. Root canal therapy also should be given to those still having symptoms. Root canal therapy should be given as possible as can if bone destruction was aggravated by pulp necrosis.
