To systematically review the recent scientific evidence about the hygiene practices of removable prostheses relative to the effectiveness, colour and dimensional stability. This review aimed also to identify patients' attitudes and habits towards denture hygiene.
Three electronic databases (MEDLINE/PubMed, Scopus and Cochrane Library) were screened, in English language, between January 1995 and December 2016. A supplementary hand search in the reference list of the identified articles was also performed. Controlled clinical trials (CCTs) involving patients with no clinical signs of denture stomatitis along with a comprehensive aim to assess the effectiveness of hygiene interventions and their impact on prosthesis colour and dimensional stability were eligible for inclusion.
Following a thorough screening of titles/abstracts/full texts and consideration of the defined inclusion criteria, 21 CCTs examined the effectiveness of the hygiene approaches, 3 evaluated the colour stability of dentures subjected to hygiene practices, 2 examined the dimensional stability of dentures following microwave disinfection and 30 studies registered patients' attitudes and habits towards denture hygiene.
Combined application of different hygiene interventions, including brushing or ultrasound vibration in conjunction with chemical agents, leads to more effective outcomes (reduction in denture biofilm percentage and/or number of microorganisms' colony-forming units). The dimensional stability seems to be unaltered, but the number of clinical trials was limited. Critical concentrations of cleansing solutions along with the duration of their implementation influence the serviceability of dentures regarding colour stability. Brushing represents the most commonly applied hygiene practice, while denture wearers' attitudes are not complied with the recommended guidelines considering the reported frequency of hygiene practices and the continuous denture wear.
系统回顾近期关于可摘义齿卫生措施在有效性、颜色和尺寸稳定性方面的科学证据。本综述还旨在确定患者对义齿卫生的态度和习惯。
检索了1995年1月至2016年12月期间的三个英文电子数据库（MEDLINE/ PubMed、Scopus和Cochrane图书馆）。还对已识别文章的参考文献列表进行了补充手工检索。纳入标准为涉及无义齿性口炎临床体征患者的对照临床试验（CCT），且全面评估卫生干预措施的有效性及其对义齿颜色和尺寸稳定性的影响。
在对标题/摘要/全文进行全面筛选并考虑既定纳入标准后，21项CCT研究了卫生方法的有效性，3项评估了进行卫生措施后义齿的颜色稳定性，2项研究了微波消毒后义齿的尺寸稳定性，30项研究记录了患者对义齿卫生的态度和习惯。
不同卫生干预措施的联合应用，包括刷牙或超声振动结合化学制剂，能产生更有效的结果（义齿生物膜百分比降低和/或微生物菌落形成单位数量减少）。尺寸稳定性似乎未改变，但临床试验数量有限。清洁溶液的临界浓度及其使用持续时间会影响义齿在颜色稳定性方面的适用性。刷牙是最常用的卫生措施，然而考虑到报告的卫生措施频率和义齿持续佩戴情况，义齿佩戴者的态度并未遵循推荐指南。
