目的：评估牙周-正畸联合治疗对成人牙周病患者切牙区美学重建的作用。方法选择13例患者接受牙周基础治疗及正畸治疗，在全口洁治后获得统一基线，在牙周基础治疗后3个月及正畸治疗结束对13例患者的102颗切牙进行牙周临床检查，比较治疗前后的差异。检查项目包括：探诊深度（PD），每颗牙检查6个位点，102颗切牙共612个位点；探诊出血（BOP），每颗牙检查颊、舌两个位点，共204个位点；龈乳头指数（PI）和龈乳头高度（PH），共128个龈乳头。结果牙周基础治疗3个月后，79.58%（487/612）的位点PD≤3mm，88.73%（181/204）的位点BOP阴性，较基线时[分别为26.31%（161/612）和22.06%（45/204）]明显改善。正畸治疗前，仅8个龈乳头的PI为Ⅲ级，龈乳头完全充盈牙间隙，21个为Ⅱ级；正畸治疗结束后，51个龈乳头的PI达到Ⅲ级，68个龈乳头的PI达到Ⅱ级。PH由正畸治疗前的（1.69±0.57）mm增加到治疗后的（2.84±0.62）mm，治疗前后的差异有统计学意义（P<0.05）。结论牙周-正畸联合治疗有利于成人牙周病患者切牙区的美学重建。

Objective To evaluate the role of the combined periodontic-orthodontic treatment in the esthetic reconstruc-tion of the anterior teeth area following periodontitis. Methods Thirteen adult patients with anterior teeth displacements were treated. The probing pocket depth (PD; 102 teeth, 612 sites), bleeding on probing (102 teeth, 204 sites), papilla index (PI; 128 papillae), and papillary height (PH; 128 papillae) of each patient were assessed at baseline, 3 months after the initial therapy, and the end of the orthodontic treatment. Non-parametric and paired-sample t tests were carried out for the statistical analysis of the data. Results Three months after initial therapy, the sites with PD≤3 mm accounted for 79.58% (487/612) of the observed teeth, and 88.73% (181/204) of the buccal and lingual sites of the teeth showed negative bleeding on probing. These findings were better than those at baseline [26.31% (161/612) and 22.06% (45/204), respectively] (P<0.05), but no sig-nificant difference was observed compared with pro-orthodontic treatment (P>0.05). Prior to orthodontic treatment, the levels of the PI of 8 and 21 papillae were Ⅲ and Ⅱ, respectively, among the 128 observed papillae. After the orthodontic treatment, 51 papillae were at level Ⅲ and 68 papillae were at level Ⅱ. The PH of the 102 papillae was 2.84 mm±0.62 mm after ortho-dontic treatment. This result indicated significant difference compared with that of pre-orthodontic treatment (1.69 mm± 0.57 mm) (P<0.05). Conclusion After initial therapy, moderate orthodontic teeth movements may reconstruct the interpro-ximal soft tissue, with esthetic improvement of the papillary level and resolution of the periodontal defects.
