摘要
目的探讨牙周基础治疗对重度牙周炎患者松动牙临床牙周指标与咬合能力的影响。方法选择31例重度牙周炎患者共285颗松动牙,按松动程度分为Ⅰ°松动组164颗、Ⅱ°松动组94颗、Ⅲ°松动组27颗,并按松动发生的牙位分为前牙松动组99颗、后牙松动组186颗。在治疗前及基础治疗完成6周后记录松动牙的松动度改善情况、牙周袋探诊深度、附着丧失、出血指数、咬合受力百分比与咬合接触面积。结果治疗后,Ⅰ°松动组、Ⅱ°松动组、Ⅲ°松动组松动度改善率分别为50. 00%(82/164)、60. 64%(57/94)、66. 67%(18/27),探诊深度、附着丧失、出血指数均较治疗前降低(均P <0. 05);Ⅰ°松动组、Ⅱ°松动组咬合接触面积较治疗前增大(P <0. 05)。治疗后,前牙松动组、后牙松动组松动度改善率分别为43. 43%(43/99)、61. 29%(114/186),探诊深度、附着丧失、出血指数较治疗前降低(均P <0. 05);前牙松动组咬合受力百分比及咬合接触面积均较治疗前减少,而后牙松动组咬合受力百分比及咬合接触面积均较治疗前增大(均P <0. 05)。结论重度牙周炎患者经过基础治疗后,松动牙松动情况、牙周及咬合指标均获得改善,但松动度较轻的患牙或后牙的咬合改善更为明显。
Objective To explore the effect of periodontal initial therapy on the clinical periodontal indices and occlusion of loose teeth in the patients with severe periodontitis. Methods A total of 285 loose teeth from 31 patients with severe periodontitis were selected.The teeth were divided into Ⅰ° group( n = 164),Ⅱ° group( n = 94) and Ⅲ° group( n = 27) according to the degree of mobility and were also divided into anterior teeth group( n = 99) and posterior teeth group( n = 186) according to the location of loose teeth. Before treatment and at 6 weeks after initial therapy,the indices of affected teeth were recorded,including the improvement of mobility,probing depth of periodontal pocket,attachment loss,blood index,occlusal force percentage and occlusal contact area. Results After treatment,in the Ⅰ°group,Ⅱ° group and Ⅲ° group,the mobility improvement rates were 50. 00%( 82/164),60. 64%( 57/94) and 66. 67%( 18/27) respectively,and probing depth,attachment loss and blood index decreased compared with those before treatment( all P < 0. 05); the occlusal contact areas of the Ⅰ° group and the Ⅱ° group were larger compared with the areas before treatment( P < 0. 05). After treatment,in the anterior teeth group and the posterior teeth group,the mobility improvement rates were 43. 43%( 43/99) and 61. 29%( 114/186) respectively,and probing depth,attachment loss and blood index decreased compared with those before treatment( all P < 0. 05); the occlusal force percentage and occlusal contact area decreased in the anterior teeth group,but increased in the posterior teeth group compared with those before treatment( all P < 0. 05). Conclusion For the patients with severe periodontitis after initial therapy,the loose teeth achieve the improvement in the mobility,periodontal and occlusal indices,but the improvement of occlusion is more obvious in the affected teeth with less mobility or posterior teeth.
