Periodontal disease is one of the common dental and oral health problems and can cause damage to the dental supporting tissue if not treated properly. Various approaches have been developed to prevent and treat this disease, one of which is the use of probiotics. Probiotics are known to help maintain the balance of the oral microbiota, reduce inflammation, and inhibit the growth of pathogenic bacteria that contribute to periodontal disease. This study aims to review the role of probiotics in improving periodontal tissue health based on recent studies. The method used in this review involved searching and selecting journals from various scientific databases relevant to the topic of probiotics and periodontal health. The inclusion criteria included studies that addressed the effects of probiotics on periodontal health, while the exclusion criteria were applied to studies with methodologies that were unclear or irrelevant to the focus of the study. The results of the review show that probiotics, especially from the genera Lactobacillus and Bifidobacterium, have the potential to reduce gingival inflammation, reduce the depth of periodontal pockets, and improve overall periodontal health. The main mechanisms found involve competition with pathogenic bacteria, modulation of immune responses, as well as the production of natural antimicrobial compounds. In conclusion, probiotics have the potential to be an effective adjunct therapy in maintaining the health of periodontal tissue. However, more research is needed to determine the optimal dosage, duration of use, as well as its long-term effectiveness in periodontal care.
