侵袭性牙周炎伴错牙合畸形患者牙周-正畸联合治疗前、后牙周状况评价

摘要

目的:观察和评价侵袭性牙周炎(AgP)伴错牙合畸形患者牙周-正畸联合治疗前、后的牙周状况.方法:选择2010-2016年就诊于广西医科大学附属口腔医院门诊的12例AgP伴错牙合畸形患者,观察牙周-正畸联合治疗前、后菌斑指数(PLI)、牙周探诊深度(PD)、探诊后出血(BOP)百分率、牙周临床附着水平(CAL)、前牙区切缘到龈乳头高点的距离(PID)、影像学硬骨板出现百分率等指标.结果:正畸前(P1)、正畸治疗第6个月(P2)、正畸结束(P3)、正畸结束后6个月(P4)与初诊时(P0)比较,牙周PLI、PD、BOP以及PD≥5mm的深牙周袋百分率均有显著降低(均P＜0.01),P4分别与P0、P1、P3比较,硬骨板出现比率显著增加(P＜0.01),CAL、PID治疗前、后比较,差异无统计学意义(P＞0.05).结论:AgP伴错牙合畸形患者,在规范的牙周治疗后和严密的牙周监控下,正畸治疗能纠正错牙合畸形,不会引起牙周组织的进一步破坏和牙周炎症的加重,是安全可行的.%Objective:To observe and evaluate the periodontal status of patients with aggressive periodontitis (AgP) and malocclusion before and after periodontal-orthodontic treatment.Methods:12 cases of AgP with malocclusion were included.Plaque index (PLI),pocket depth (PD),bleeding on probing (BOP) rate,clinical attachment level (CAL),the distance between top of the papilla and incisal edge (PID),and the rate of lamina dura formation were observed and compared before and after combined periodontal-orthodontic treatment.Results:PLI,PD,and the rates of BOP and PD≥5 mm before orthodontics (P1),at 6 months of orthodontic treatment (P2),at the end of orthodontic treatment (P3) and 6 months after orthodontic treatment (P4) were decreased,compared with early diagnosis (P0) (P＜ 0.01).The rate of lamina dura formation at P0,P 1 and P3 was notably higher than that at P4 (P＜0.01).There was no significant difference in CAL and PID before and after treatment (P＞ 0.05).Conclusion:Orthodontic treatment could correct malocclusion in patients with AgP and malocclusion under strict periodontal monitoring.It could not cause damage to periodontal tissue and aggravate periodontal inflammation,and was safe and feasible.
