This study compares and evaluates the efficacy of ozonated water irrigation (OZI) and powered toothbrushing on the oral health and microbial status of mentally challenged individuals.
Thirty individuals of age range 15-30 years with a mild-to-moderate level of mental retardation (MR) and gingival inflammation participated in this double-blind randomized controlled clinical trial. Total duration of the study was 45 days consisting of two clinical phases (phase I, i.e., aided) and phase II, i.e. unaided) of the duration of 21 days in each phase, with a washout period of 3 days between the two phases. With a split-mouth design, sites from each subject were randomly allocated into two treatment groups: Powered Toothbrushing (PB) and OZI were randomly done for each half side of the mouth of each subject. Subgingival plaque samples were collected from sites of both the treatment groups and sent for microbial analysis. Clinical and microbial parameters were measured before and after the treatment.
Significant improvement of the clinical and microbial parameters was found in both treatment groups. However, intergroup differences in the parameters were statistically nonsignificant.
OZI could serve as an alternative or adjunct to powered toothbrushes for people with MR.
本研究比较并评估了臭氧水冲洗（OZI）和电动牙刷对智障人士口腔健康和微生物状况的疗效。
30名年龄在15 - 30岁之间、患有轻度至中度智力障碍（MR）且有牙龈炎症的个体参与了这项双盲随机对照临床试验。研究总时长为45天，包括两个临床阶段（第一阶段，即辅助阶段；第二阶段，即非辅助阶段），每个阶段时长为21天，两阶段之间有3天的洗脱期。采用分口设计，将每个受试者的部位随机分为两个治疗组：电动牙刷组（PB）和臭氧水冲洗组，对每个受试者口腔的每一侧分别随机进行相应处理。从两个治疗组的部位采集龈下菌斑样本并送去进行微生物分析。在治疗前后测量临床和微生物参数。
两个治疗组的临床和微生物参数均有显著改善。然而，两组参数之间的差异在统计学上无显著意义。
对于智障人士，臭氧水冲洗可作为电动牙刷的替代方法或辅助手段。
