Simplified periodontal therapy might be a pragmatic strategy for public health programmes targeting Indigenous Australian adults. The objective of this randomized controlled trial was to evaluate oral health effects of single-visit, non-surgical periodontal therapy compared to no treatment.
This parallel-group, randomized, open label clinical trial enrolled 273 Indigenous Australians aged ≥18 years with periodontitis. Intervention participants received full-mouth periodontal scaling and root planing during a single visit while the control group received no treatment. Endpoints were summary variables derived from clinical assessments of probing depth, clinical attachment loss, plaque, calculus and gingival bleeding before treatment and 3 months later.
Endpoints could be calculated for 169 participants with follow-up data. Compared to the control group, there were statistically significant reductions in extent of shallow pockets: PD ≥4 mm (mean difference -2.86, [95% CI -5.01 to -0.71], p = 0.009) and gingival bleeding (mean difference -0.25, [95% CI -0.43 to -0.08], p = 0.005) but not deeper pockets PD ≥5 mm (mean difference -0.48, [95% CI -1.78 to 0.82], p = 0.468) or plaque scores.
Periodontal therapy produced improvements in shallow periodontal pockets and measures of gingival bleeding in these Indigenous Australians.
简化牙周治疗可能是针对澳大利亚原住民成年人的公共卫生计划的实用策略。本随机对照试验的目的是评估单次非手术牙周治疗与不治疗相比对口腔健康的影响。
这项平行组、随机、开放标签临床试验纳入了 273 名年龄≥18 岁且患有牙周炎的澳大利亚原住民。干预组的参与者在一次就诊时接受全口牙周刮治和根面平整，而对照组则不接受治疗。终点是从治疗前和 3 个月后的探诊深度、临床附着丧失、菌斑、牙石和牙龈出血的临床评估中得出的综合变量。
169 名有随访数据的参与者可计算终点。与对照组相比，浅牙周袋的程度有统计学显著降低：PD≥4mm（平均差异-2.86，[95%CI-5.01 至-0.71]，p=0.009）和牙龈出血（平均差异-0.25，[95%CI-0.43 至-0.08]，p=0.005），但 PD≥5mm 的深牙周袋（平均差异-0.48，[95%CI-1.78 至 0.82]，p=0.468）和菌斑评分没有差异。
牙周治疗改善了这些澳大利亚原住民的浅牙周袋和牙龈出血的测量指标。
