The relation between Actinomyces and denture stomatitis

Abstract   Background & Aim: Denture induced stomatitis occurs in 24-60 percents of edentulous people who have dentures.Up to now some etiologic factors have been introduced for denture stomatitis but there are some controversies.In some literatures some other microorganisms have been isolated besides candida albicans as main reasons. According to the incidence of denture induced stomatitis and the resistance and recurrence to treatment with antifungal drugs in some of these cases this research was done to evaluate the role of actinomycets in these lesions Material and methods: In this case control study the samples were collected from15 persons with removable full dentures without any denture stomatitis and 15 persons with removable full dentures with denture stomatitis lesions. Both groups were matched according to age, gender،duration of denture wearing، systemic diseases ,oral hygine, smoking,xerostomia,use of medicines and The samples were transported to the lab in thyo culture and incubated in  37 C for 1 week and then transported to Brain and Heart infusion culture .After sample processing for microscopic evaluation for detecting actinomycets ،the results were  analyzed with chi-square test by using spss soft ware version14. Results: The results shows that 5 of 15 (33.3%)  in control group and 11 of 15 (73.3%) in case group  were actinomycets positive. (p <0.03) Conclusions: It seems that, actinomycets can play a role in denture stomatitis، besides candida albicans. Key words: Actinomyces, Denture, Stomatitis , Candida albicans
