To evaluate the role of the combined periodontic-orthodontic treatment in the esthetic reconstruc- tion of the anterior teeth area following periodontitis.
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.
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).
After initial therapy, moderate orthodontic teeth movements may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level and resolution of the periodontal defects.
评估牙周正畸联合治疗在牙周炎后前牙区美学重建中的作用。
对13例有前牙移位的成年患者进行治疗。在基线、初始治疗后3个月以及正畸治疗结束时,评估每位患者的探诊深度(PD;102颗牙,612个位点)、探诊出血(102颗牙,204个位点)、龈乳头指数(PI;128个龈乳头)和龈乳头高度(PH;128个龈乳头)。对数据进行非参数检验和配对样本t检验进行统计分析。
初始治疗后3个月,PD≤3mm的位点占观察牙的79.58%(487/612),牙齿颊舌侧位点探诊出血阴性的占88.73%(181/204)。这些结果优于基线时的结果[分别为26.31%(161/612)和22.06%(45/204)](P<0.05),但与正畸治疗前相比无显著差异(P>0.05)。正畸治疗前,在观察的128个龈乳头中,8个和21个龈乳头的PI水平分别为III级和II级。正畸治疗后,51个龈乳头为III级,68个龈乳头为II级。正畸治疗后102个龈乳头的PH为2.84mm±0.62mm。该结果与正畸治疗前(1.69mm±0.57mm)相比有显著差异(P<0.0�)。
初始治疗后,适度的正畸牙齿移动可重建邻间隙软组织,改善龈乳头水平的美观并解决牙周缺损问题。
