This retrospective study aimed to evaluate the outcomes of nonsurgical periodontal therapy performed by senior dental students.
Electronic records of patients treated by senior dental students at the comprehensive care clinic in King Abdulaziz University Dental Hospital were reviewed retrospectively. Patients diagnosed with gingivitis or periodontitis who had undergone at least one session of scaling and root planing were included in this study. The following periodontal parameters were assessed: BOP, PI, PD and number of residual pockets.
A total of 618 patients were included in this study (60.2% females and 39.8% males). BOP reduced from a median of 40% (IQR: 26.0%-62.0%) at baseline to 13% (IQR: 9.0%-20.3%) at re-evaluation in the gingivitis group (p < 0.0005). Similarly, a significant reduction in BOP, from 45% (IQR: 28.0%-64.3%) at baseline to 14% (IQR: 9.0%-21.5%) after phase I therapy, was observed in the periodontitis group (p > 0.001). In both groups, 31%-32% of patients had BOP < 10 at re-evaluation. PD of ≥ 5 mm was observed in 50.8% of patients with periodontitis at baseline; however, 38% of these patients had no residual pockets at re-evaluation.
NSPT performed by senior dental students was effective in improving the periodontal status of the patients. Both gingivitis and periodontitis patients showed significant improvement in BOP and PI. Approximately, 32% of patients showed a reduction in BOP suggestive of a bleeding score associated with periodontal health. Moreover, patients diagnosed with periodontitis exhibited a significant reduction in the number of sites with deep probing (≥ 5).
本回顾性研究旨在评估高年级牙科学生进行非手术牙周治疗的效果。
回顾性分析在阿卜杜勒阿齐兹国王大学牙科医院综合护理诊所接受高年级牙科学生治疗的患者的电子记录。本研究纳入了诊断为牙龈炎或牙周炎且至少接受过一次龈下刮治和根面平整治疗的患者。评估以下牙周参数：探诊出血（BOP）、菌斑指数（PI）、牙周袋深度（PD）和残余牙周袋数量。
本研究共纳入618例患者（女性占60.2%，男性占39.8%）。在牙龈炎组中，BOP从基线时的中位数40%（四分位间距：26.0%-62.0%）降至重新评估时的13%（四分位间距：9.0%-20.3%）（p＜0.0005）。同样，在牙周炎组中，观察到BOP从基线时的45%（四分位间距：28.0%-64.3%）显著降至I期治疗后的14%（四分位间距：9.0%-21.5%）（p＞0.001）。在两组中，31%-32%的患者在重新评估时BOP＜10。基线时，50.8%的牙周炎患者牙周袋深度≥5mm；然而，这些患者中有38%在重新评估时没有残余牙周袋。
高年级牙科学生进行的非手术牙周治疗有效地改善了患者的牙周状况。牙龈炎和牙周炎患者的BOP和PI均有显著改善。约32%的患者BOP降低，提示出血评分与牙周健康相关。此外，诊断为牙周炎的患者深牙周袋（≥5mm）部位数量显著减少。
