Obesity is considered a risk factor for periodontitis. However, its impact on periodontal therapy is not clearly determined. The aim of this case-control study was to evaluate the association between adiposity measurements, non-surgical periodontal treatment outcomes and influencing factors in patients with chronic periodontitis.

Eighteen obese and 18 normal weight (NW) patients were included in the study. Waist-to-hip ratio (WHR), plaque index (PI), bleeding on probing (BOP), pocket depth (PD) and clinical attachment level (CAL) were measured at baseline, 3 and 6 months after treatment. Univariable and multivariable analysis were used to evaluate the influence of gender, age, baseline % of PD>3mm, WHR, and obesity on periodontal treatment outcomes.

Demographic and periodontal characteristics at baseline were similar in both groups. All periodontal parameters were improved during treatment in both groups. PD reduction and CAL gain were 0.88 mm and 0.84 mm in NW, 0.79 mm and 0.68 mm in obese. The difference of moderate to deep pocket (PD>5mm) percentages between baseline and 6 months examinations was 9.1% in NW and 6.08% for obese. Multivariable analysis showed that obesity negatively influenced changes of PD>5mm percentages. This influence was also observed at 3 months for improving sites (PD decrease>2 mm between examinations) if WHR was also considered in the analysis.

A negative association between adiposity measurements and periodontal treatment outcomes was mainly observed for moderate to deep pockets. Consideration of WHR and other influencing factors amplified the negative effect of obesity on periodontal treatment outcomes.
