The aim of the present study was to investigate plaque levels following sonic-powered and manual toothbrushing in subjects with dental implants.
This study included 36 male and 47 female partially edentulous patients (age range 45-78 years, mean age 59.8 years) that were randomly assigned to one of two treatment groups: the sonic toothbrush group (n = 42; Philips Sonicare FlexCare® toothbrush) or the manual toothbrush group (n = 41; Oral-B P40®). Clinical, microbiological and immunological examinations were performed blinded at baseline and after 3, 6, 9 and 12 months. Microbiological analyses were performed by real-time polymerase chain reaction. Immunological analyses (prostaglandin E2) were performed by chromatography-electrospray spectrometry.
The plaque index difference between baseline and 12 months at implants showed no significant difference between sonic or manual toothbrushing in a two-sided Mann-Whitney test (W = 773.5, P = 0.426, 95% CI -0.64 to 0.20). At the end of the study, there were no significant changes in plaque index, bleeding on probing, gingival index, pocket probing depth, gingival recession, clinical attachment level or the microbiological and immunological outcomes at implants or teeth in either group.
This study uncovered no significant difference between sonic and manual toothbrushing for plaque reduction at implants and teeth. Both toothbrushes maintain healthy peri-implant soft tissue.
本研究旨在调查牙种植体患者使用声波牙刷和手动牙刷后的牙菌斑水平。
本研究纳入了36名男性和47名女性部分牙列缺损患者（年龄范围45 - 78岁，平均年龄59.8岁），他们被随机分配到两个治疗组之一：声波牙刷组（n = 42；飞利浦Sonicare FlexCare®牙刷）或手动牙刷组（n = 41；欧乐B P40®）。在基线以及3、6、9和12个月后进行了盲法临床、微生物学和免疫学检查。微生物学分析通过实时聚合酶链反应进行。免疫学分析（前列腺素E2）通过色谱 - 电喷雾光谱法进行。
在双侧曼 - 惠特尼检验中，种植体处基线与12个月时的牙菌斑指数差异在声波牙刷和手动牙刷之间无显著差异（W = 773.5，P = 0.426，95% CI -0.64至0.20）。在研究结束时，两组中种植体或牙齿处的牙菌斑指数、探诊出血、牙龈指数、牙周袋探诊深度、牙龈退缩、临床附着水平以及微生物学和免疫学结果均无显著变化。
本研究发现声波牙刷和手动牙刷在减少种植体和牙齿上的牙菌斑方面无显著差异。两种牙刷均能维持健康的种植体周围软组织。
