对义齿菌斑的研究还没有达到与牙菌斑相同的程度，虽然在微生物组成上有许多相似之处，但也有一些显著的差异。义齿引起的口腔炎与不良的义齿卫生、产酸能力更强的菌斑和白色念珠菌的存在有关。专性革兰氏阴性厌氧微生物，虽然存在于义齿菌斑中，但很少被专门研究。从假牙中分离出了包括大肠菌群和葡萄球菌在内的机会性病原体。与部分义齿相邻的牙齿更容易患龋齿和牙周病，这可能是由于义齿/牙齿界面的菌斑堆积增加所致。关于假牙相关的恶臭的研究成果很少。这种惰性材料为菌斑生物膜提供了底物，菌斑生物膜包括一系列产生气味的物种。假牙佩戴者舌头的微生物学尚未得到专门研究。因此，假牙佩戴者的恶臭的性质、来源和程度尚不清楚，但存在许多能够产生恶臭化合物的物种。假牙佩戴者呈现的广泛的年龄和健康范围进一步混淆了调查。由于日益增长的老年人口的美容和与健康相关的原因，需要在这一领域进一步开展工作。
Denture plaque has not been studied to the same extent as dental plaque, and although there are many similarities in microbial composition, there are some significant differences. Denture-induced stomatitis is associated with poor denture hygiene, a more acidogenic plaque and the presence of Candida albicans. Obligate Gram-negative anaerobic micro-organisms, although present in denture plaque, have rarely been specifically investigated. Opportunist pathogens including coliforms and staphylococci have been isolated from dentures. Teeth adjacent to partial dentures are more susceptible to caries and periodontal diseases, perhaps due to an increased plaque buildup at the prosthesis/tooth interface. Little work has been published on malodour associated with dentures. The inert material provides a substratum for the plaque biofilm, which encompasses a range of odour-producing species. The microbiology of the tongue in denture wearers has not been specifically studied. Thus the nature, origin and extent of malodour in denture wearers is ill-defined, but many species capable of producing malodorous compounds are present. The wide age and health range presented by denture wearers further confounds investigation. There is a need for further work in the area, both for cosmetic- and health-associated reasons in the increasing elderly population.
