About
The aim of this study is to evaluate the effects of probiotic supplementation and diet-supported probiotic use on periodontal clinical parameters in individuals with periodontitis. A total of 120 female participants aged between 20-60 years, diagnosed with periodontitis and without systemic diseases, were included in the study. Participants are randomly assigned into three groups: a control group (conventional treatment), a probiotic group (conventional treatment + probiotics), and a diet + probiotic group (conventional treatment + probiotics + personalized diet). Clinical evaluations are performed using measurements of probing depth (PD) and clinical attachment loss (CAL), while dietary intake is assessed using three-day food records. The collected data will be analyzed using SPSS 21.0 software, and a p-value <0.05 will be considered statistically significant.
Full description
Periodontitis is a chronic inflammatory disease that results in the destruction of the supporting tissues of the teeth, potentially leading to tooth loss if left untreated. While conventional periodontal treatment focuses on mechanical removal of plaque and calculus, there is increasing interest in adjunctive therapies that target the host response and the oral microbiome.
Probiotic supplementation has been suggested as a potential supportive approach in periodontal therapy, owing to its ability to modulate the microbial balance and reduce inflammation. Moreover, dietary habits-especially the intake of protein, fiber, sugar, and carbohydrates-may influence periodontal health by affecting systemic and local inflammatory responses.
This randomized controlled clinical trial investigates the effects of probiotic supplementation and a personalized anti-inflammatory diet in individuals with periodontitis. A total of 120 female participants aged 20 to 60 years, without systemic diseases, are included. The participants are randomly assigned into three parallel groups:
Control group: conventional non-surgical periodontal treatment
Probiotic group: conventional treatment + probiotic supplementation
Diet + probiotic group: conventional treatment + probiotic supplementation + personalized diet counseling
The intervention period lasts six weeks. Clinical periodontal parameters, including probing depth (PD) and clinical attachment loss (CAL), are assessed at baseline and at the end of the study. Dietary intake is evaluated through three-day food records collected before and after the intervention.
This study aims to explore the potential of integrating probiotics and diet modifications into a holistic periodontal treatment model. Results will be analyzed following data collection and are not included in this section.
