Summary

In this randomized controlled trial, it was aimed to evaluate the effect of probiotics (chewable tablets) and kefir consumption in the initial periodontal treatment of periodontitis patients on the change of oral microbiota and treatment. In this clinical trial, 36 systemically healthy volunteers who were diagnosed with periodontitis who were admitted to Gazi University Faculty of Dentistry, Department of Periodontology were included. Besides the inclusion criteria, the nutritional habits of the patients were evaluated by questionnaire. For diagnosis, plaque index, gingival index, bleeding on probing, periodontal probing depth and clinical attachment level were examined. Patients were randomly divided into 3 groups; probiotic, kefir and control group. Following the periodontal diagnosis, clinical index records of the patients and subgingival microbial samples were obtained. The supragingival plaque sample was removed and the subgingival microbial dental plaque sample was gently taken with a sterile Gracey curette. In the same session, periodontal initial treatment was started. According to the groups, they were involved simultaneously with the treatment, kefir group was advised to consume kefir as a liquid once a day in 14 days; probiotics group was advised to consume as a chewable tablet once a day in 14 days; the control group was advised without additional food supplements. Periodontal indexes were repeated in the 1st and 3rd months. Subgingival plaque samples were taken at baseline and at 3 months and DNA sequencing was performed for Tanneralla forsythia (T. forsythia), Porphyromonas gingivalis (P. gingivalis), and Treponema denticola (T. denticola).
