Abstract
OBJECTIVE: Obesity and periodontitis are recognized as a major public health problem. The aim of this study was to investigate the response of different body mass index(BMI) groups to non-surgical periodontal treatment(NSPT). METHODS: We retrospectively reviewed the medical records, including baseline medical information and BMI, of patients with periodontal disease. We also analyzed periodontal indices, including periodontal pocket depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), before and after NSPT to assess the correlation between BMI and the effectiveness of NSPT. RESULTS: A total of 147 patients participated in this study, including 88 individuals in the normal BMI group with an average age of 49.02 ± 10.05 years and 59 individuals in the high BMI group with an average age of 48.15 ± 8.78 years. The results showed that the periodontal index of the abnormal BMI group was higher than that of the normal BMI group both before and after NSPT. NSPT had significant effects on patients with periodontitis in both the normal and abnormal BMI groups. The abnormal BMI group exhibited a significantly higher change in the percentage of PD ≧ 4 mm compared to the normal BMI group (p = 0.019). CONCLUSION: Despite the fact that Taiwan individuals have lower BMI groupings, those with abnormal BMI exhibit less favorable periodontal indices compared to those with normal BMI. However, NSPT has shown promising results in improving periodontal disease among individuals with abnormal BMI. Encouragement should be given to individuals with generalized severe periodontitis and a high BMI to actively consider receiving periodontal treatment. CLINICAL RELEVANCE: Despite generally lower BMI in Taiwan, individuals with abnormal BMI exhibit less favorable periodontal health. NSPT shows promise in improving their periodontal condition. Tailored interventions may enhance periodontal outcomes.
