牙周基础治疗对牙槽骨重度吸收切牙的短期疗效

Short Term Effect of Initial Periodontal Therapy on Incisors with Severe Bone Loss

目的:观察牙周基础治疗对牙槽骨重度吸收切牙的短期疗效。方法:对25颗牙槽骨重度吸收的切牙进行牙周探诊、牙龈退缩、松动度、咬合创伤、牙髓活力以及X线检查,进行牙周基础治疗,对治疗前和治疗后半年的临床指标进行比较和分析。结果:与治疗前相比,牙周基础治疗半年后,牙周探诊深度和松动度均明显改善,差异有统计学意义(P<0.001)。牙龈退缩也明显增加(P<0.001)。根尖片显示牙槽骨的高度有少量恢复。结论:牙周组织严重破坏的切牙牙周基础治疗后短期疗效显著。长期效果尚待进一步观察。

Objective： To observe the short term effect of initial periodontal therapy on incisors with severe bone loss. Methods： Twenty--five incisors with severe bone loss were included from 17 patients with chronic periodonti tis. Baseline examination included periodontal probing, gingival recession, mobility, trauma from occlusion, pulp vitality and bone loss evaluation via X-- ray examination. Initial periodontal therapy included oral hygiene instruc tion, scaling and root planning. Occlusal adjustment, root canal therapy and splinting were performed if indicated. Six--months after initial periodontal therapy, PD, gingival recession, mobility and bone loss in X--ray examination were re--evaluated. Results： Six months after initial periodontal therapy, both PD and mobility improved signifi cantly （P〈0. 001）. Gingival recession increased significantly （P〈0. 001）. Peri--apical films after therapy showed signs of bone fill and repair. Conclusion： Through initial per;,odontal therapy, incisors with severe bone loss could a- chieve stable effect in a short term, while long term effect needs further study.
