目的:观察粘接性牙周夹板固定修复治疗慢性牙周炎的临床效果。方法:选择25例(93颗松动患牙)慢性牙周炎患者,记录牙周治疗前、采用粘接性牙周夹板固定修复后即刻、3、6及12个月的牙周状况,包括菌斑指数(PLI)、探针深度(PD)、牙龈出血指数(BOP)、牙龈指数(GI)和附着丧失(AL)的变化;检测牙龈龈沟液中卟啉单胞菌、血链球菌数量的变化;评估患者行固定夹板修复后对美观、舒适、咀嚼、发音等方面的满意度。结果:经牙周夹板固定修复后,各阶段的PLI、PD、GI和AL的指标值与治疗前相比差异均有统计学意义(P<0.05),但固定后各阶段之间的牙周临床指标差异无统计学意义(P>0.05);牙龈卟啉单胞菌和血链球菌数的数量在固定后各阶段较治疗前均显著减少(P<0.05),但固定期间各阶段比较差异不明显(P>0.05);固定修复后,各阶段患者的满意度均较高。结论:慢性牙周炎患者经完善的牙周基础治疗后,应用粘接性牙周夹板固定修复,能够有效固定患者松动患牙,恢复其咀嚼功能,有效地控制慢性牙周炎的发展。
Objective: To observe the clinical effect of adhesive periodontal splints in the treatment of chronic periodontitis. Methods: Twenty-five patients (93 loosed teeth) with chronic periodontitis were selected and their periodontal status was recorded immediately before, 3, 6 and 12 months after periodontal treatment with adhesive periodontal splints PLI, PD, BOP, GI and AL were measured. The number of Porphyromonas spp. And S. Sanguis in gingival crevicular fluid ; Assessment of patients with fixed splint repair, beauty, comfort, chewing, pronunciation and other aspects of satisfaction. Results: The indexes of PLI, PD, GI and AL in each stage were significantly different from those before treatment (P <0.05) after the periodontal splints were fixed and repaired, but the periodontal tissues (P> 0.05). The number of Porphyromonas gingivalis and Streptococcus sanguis decreased significantly in all stages after the treatment (P <0.05), but the difference was not significant in all stages Not obvious (P> 0.05). After the fixation and repair, the satisfaction of patients in all stages were higher. Conclusion: After periodontal basic treatment, patients with chronic periodontitis can be fixed and repaired by adhesive periodontal splints, which can effectively fix patients’ loosened teeth and restore their masticatory function and effectively control the development of chronic periodontitis.
