To assess the impact of nonsurgical periodontal treatment, performed by undergraduate dental students, on oral health-related quality of life of patients with periodontitis.
An observational, prospective, single-arm cohort study with pre‑post test involving 31 undergraduate dental students was performed. A complete periodontal examination was performed before and after receiving nonsurgical periodontal treatment. The main independent clinical variables assessed were the degree of periodontal inflammation and the number of teeth with periodontitis. Oral health-related quality of life was assessed before and after treatment through the Oral Impacts on Daily Performances (OIDP) questionnaire. The association between the extent of periodontal treatment (measured as number of treated teeth) and final OIDP score was assessed, adjusting for age, sex, and baseline OIDP, in a multiple regression model.
Thirty-four patients were enrolled and treated by the undergraduate students. The mean OIDP value (global absolute score), representing the severity and frequency of the impacts, decreased from 26.2 to 12 after treatment. The mean percentage of impact, representing the number dimensions affected by oral health (global percent score), was reduced from 13% to 6%. However, no association between the number of treated teeth and post-treatment OIDP score was observed after adjusting for age, sex, and baseline OIDP score.
Nonsurgical periodontal treatment performed by undergraduate dental students improved the oral health-related quality of life of periodontal patients, although no statistically significant association was found between the extent of periodontal treatment and the final OIDP score.
评估由本科牙科学生进行的非手术牙周治疗对牙周炎患者口腔健康相关生活质量的影响。
进行了一项观察性、前瞻性、单臂队列研究，包括 31 名本科牙科学生。在接受非手术牙周治疗前后进行了完整的牙周检查。主要的独立临床变量评估是牙周炎的炎症程度和牙周炎牙齿的数量。治疗前后通过口腔日常活动影响问卷（OIDP）评估口腔健康相关生活质量。在多元回归模型中，调整年龄、性别和基线 OIDP 后，评估牙周治疗程度（以治疗牙齿数衡量）与最终 OIDP 评分之间的关联。
共纳入 34 名患者，由本科学生进行治疗。OIDP 值（全球绝对评分）的平均值（代表影响的严重程度和频率）从治疗前的 26.2 降至治疗后的 12。代表受口腔健康影响的维度数量（全球百分评分）的平均百分比从 13%降至 6%。然而，调整年龄、性别和基线 OIDP 评分后，未观察到治疗牙齿数量与治疗后 OIDP 评分之间存在关联。
由本科牙科学生进行的非手术牙周治疗改善了牙周炎患者的口腔健康相关生活质量，但牙周治疗程度与最终 OIDP 评分之间未发现统计学显著关联。
