Oral and denture hygiene are often defective in particular with dependent persons such as geriatric subjects. The reasons are the lack of hygiene education of the subjects or those caring for them. Consequently, oral hygiene is often neglected, resulting in poor oral health and an increase in the presence of local or general infections.
This paper is a report of brushing effectiveness on microbial biofilm deposits on dentures of subjects participating in a specific oral hygiene programme.
Thirty-nine dentures of 30 subjects were assessed for 2 weeks following an educational brushing programme. Microbial biofilm was recovered using fluoresceine and then scanned and quantified by 'Mesurim' software three times: before study, after 1 and 2 weeks.
The repeated measurement procedures showed a decrease in the percentage of biofilm present (F = 15, p < 0.001) whatever the type of denture (partial or complete) and for all biomaterials.
Regular denture-brushing can improve local hygiene. Consequently, decreasing the biofilm surface can reduce the prevalence of oral pathogens, thereby contributing to the general prevention of the risks of infections such as pneumotisis.
口腔和义齿卫生往往存在缺陷，特别是在依赖他人的人群中，如老年患者。原因是患者或照顾他们的人缺乏卫生教育。因此，口腔卫生往往被忽视，导致口腔健康状况不佳，并增加局部或全身感染的风险。
本文报告了参与特定口腔卫生计划的受试者的义齿上微生物生物膜沉积物的刷牙效果。
对 30 名受试者的 39 副义齿进行为期 2 周的教育刷牙计划后评估。使用荧光素回收微生物生物膜，然后使用“Mesurim”软件三次扫描并定量：研究前、1 周后和 2 周后。
重复测量程序显示，无论义齿类型（局部或全口）和所有生物材料，生物膜的存在百分比均下降（F = 15，p < 0.001）。
定期清洁义齿可以改善局部卫生。因此，减少生物膜表面可以降低口腔病原体的流行率，从而有助于预防气栓等感染风险的总体预防。
