Severity of Candida ‐associated denture stomatitis is improved in institutionalized elders who consume Lactobacillus rhamnosus SP 1

Background This study aimed to determine the effect of the consumption of a probiotic on the clinical characteristics of Candida ‐associated denture stomatitis ( DS ) and to determine the impact of a protocol of self‐care measures in oral/prosthetic hygiene in institutionalized elders that wear removable prostheses ( RP ). The current treatment for DS is the systemic use of antifungals, as well as the replacement of these devices together with oral/prosthetic hygiene instructions. Methods This study was a randomized, controlled and triple‐blind trial. Thirty‐six elders presenting DS of different severity and who carried RP consumed milk with/without the probiotic L. rhamnosus SP 1. The prevalence and severity of DS and prevalence of Candida were determined and all participants/caregivers were trained in oral/prosthetic hygiene. Results In both groups a decrease in the prevalence of DS was observed ( P  < 0.05) but only the group that consumed probiotic throughout the trial had a significant reduction in the severity of DS and reduced Candida counts ( P  < 0.05). Educational instruction in oral/prosthetic hygiene was relevant for the participants, regarding the prevalence of this lesion. Conclusions The frequent consumption of Lactobacillus rhamnosus SP 1 and the establishment of a protocol of oral/prosthetic hygiene drastically reduced the severity of DS in institutionalized elders who wore RP .
