The Relationship between both Partial and Complete Denture Wearers and the Presence of Oral Malodour and the Effect of Denture Cleansers on the Oral Microbiota

Oral malodour may be considered a substantial concern for a sizeable percentage of the general population and as such it is important for clinicians to identify the causes of oral malodour, to treat the problem effectively. Aim: The aim of the present study was therefore to review the published literature on the presence and perception of oral malodour (halitosis) in patients wearing both removable partial or complete dentures and the effect of denture cleansers on the oral microbiota. Materials & Methods: A comprehensive electronic search of databases such as PUBMED, Cochrane, Google Scholar, EmBase and Web of Science was performed up to February 2016. Results: 55 potentially relevant reports were identified with six studies included in the review. Of the six included papers, only one study was randomised, and five studies were either non-randomised controlled clinical trials or, quasi randomised trials. The results from these studies would suggest that there was an indirect association between the presence and perception of oral malodour in both RPD and complete denture wearing patients. Conclusions: The strength of evidence was however insufficient to draw any definitive conclusions on a potential correlation of oral malodour in patients with RPDs
