AimOral hygiene‐related self‐efficacy (OHSE) describes one's confidence to successfully execute oral hygiene behaviour. The aim of this study was to investigate the long‐term course of OHSE in patients during initial periodontal therapy (IPT) and supportive periodontal therapy (SPT) and its association with clinical parameters.Materials and MethodsPatients diagnosed with periodontitis, undergoing either IPT or SPT, were evaluated at two timepoints. Clinical examination included pocket probing depths (PPDs), clinical attachment loss (CAL), bleeding on probing (BOP), plaque index (PI) and gingival index (GI). Patients' OHSE was assessed with a questionnaire. Statistical analyses included t‐tests and linear regression models.ResultsNinety‐eight patients from an initial group of 201 patients were evaluated after 4 years. The overall OHSE score increased significantly in the IPT group (mean 11.65 ± 15.6, p = .001). The increase in the OHSE category ‘interdental cleaning’ was significantly correlated with a decrease in the number of pockets requiring treatment (Spearman correlation rs = −.2349, p = .022) and periodontal inflamed surface area (PISA) (rs = −.2099, p = .042).ConclusionsPatients under IPT showed a significant increase of OHSE compared to those under SPT. Improved OHSE, particularly in interdental cleaning, appears to be associated with sustained success of periodontal therapy.

牙周治疗中口腔卫生相关的自我效能感：一项为期 4 年的纵向研究


Aim口腔卫生相关自我效能感 （OHSE） 描述了一个人成功执行口腔卫生行为的信心。本研究的目的是调查患者在初始牙周治疗 （IPT） 和支持性牙周治疗 （SPT） 期间 OHSE 的长期病程及其与临床参数的相关性。材料和方法诊断为牙周炎的患者，接受 IPT 或 SPT，在两个时间点进行评估。临床检查包括牙袋探诊深度 （PPDs） 、临床附着缺失 （CAL）、探诊出血 （BOP） 、牙菌斑指数 （PI） 和牙龈指数 （GI）。通过问卷评估患者的 OHSE。统计分析包括 t 检验和线性回归模型。结果初始组 201 例患者中的 98 例患者在 4 年后进行了评估。IPT 组的总体 OHSE 评分显着增加 （平均 11.65 ± 15.6，p = .001）。OHSE 类别“齿间清洁”的增加与需要治疗的牙周袋数量的减少（Spearman 相关 rs = −.2349，p = .022）和牙周发炎表面积 （PISA） （rs = −.2099，p = .042）的减少显著相关。结论与 SPT 组患者相比，接受 IPT 的患者显示 OHSE 显著增加。OHSE 的改善，尤其是在齿间清洁方面，似乎与牙周治疗的持续成功有关。
