摘　　要：目的:观察龈下超声根面平整在老年重度慢性牙周炎患者牙周支持治疗期间(原为维护期)的应用效果。方法:选择60岁以上诊断为重度牙周炎,经基础治疗后仍有5 mm以上牙周袋和探诊出血,为翻瓣术的适应证,且拒绝手术治疗的患者60例。分别于基础治疗后4周(基线)、6个月和12个月复诊行超声刮治前,检测菌斑指数(plaque index,PLI)、出血指数(bleeding index,BI)、探诊出血(bleeding on probing,BOP)、探诊深度(probing depth,PD)的变化。1年后对结果进行t检验。结果:与基线相比,6个月复查时所有临床牙周指数均有显著改善(P<0.01),6个月与12个月相比无显著差异(P>0.05)。结论:未经翻瓣术治疗的老年重度牙周炎患者,在其牙周支持治疗期间定期施以龈下超声治疗短期可取得较好的治疗效果。AIM ： To observe the effects of subgingival ultrasonic scaling on the aged with severe chronic periodontitis in their supportive periodontal therapy. METHODS： After basic treatment, 60 severe chronic periodontitis patients, whose periodontal pockets were deeper than 5mm and the indexes of bleeding after probing were positive, were randomly assigned to receive subgingival ultrasonic scaling because of their refusing of routine periodontal flap sur- gery. Subgingival ultrasonic scaling was carried out every 3 months. Clinical assessments for pretreatment （base line） and posttreatment （ 6 and 12 months ） included plaque index （ PLI ）, bleeding index （BI）, bleeding on probing （BOP） and probing depth （PD）. A t- test was used to detemline differences in assessment values. RESULTS： When the results were compared with the base line, all clinical periodontal indexes improved significantly（ P 〈 0.05 ） ; but there was no obvious difference （P 〉0.05） between the indexes at the 6 month and 12 month. CONCLUSION： Acceptable curative effect can be achieved by the regular application of ultrasonic treatment to the aged with severe chronic periodontitis.
