Obesity and periodontitis are chronic inflammatory conditions that may share biological pathways. This pilot randomized controlled study compared adults with obesity and stage I-III periodontitis assigned to laparoscopic sleeve gastrectomy or non-surgical management. Participants underwent body measurements, a full-mouth periodontal examination, and unstimulated saliva collection at baseline, 3 months, and 6 months. Salivary interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were measured by enzyme-linked immunosorbent assay. The primary outcomes were changes in salivary IL-6 and TNF-α. Secondary outcomes included changes in plaque index, bleeding on probing, probing pocket depth, and clinical attachment level. Body weight and body mass index were measured as contextual outcomes, and exploratory analyses examined associations between cytokine and periodontal changes. The pilot was intended to test feasibility, refine measurement procedures, and estimate preliminary effect sizes for a future definitive trial.
Inclusion Criteria:
Exclusion Criteria:
• Smoking more than 10 cigarettes per day.
The intervention was open label. The manuscript does not report blinding of the periodontal examiner or laboratory personnel.
Participants allocated to SG underwent laparoscopic sleeve gastrectomy and completed anthropometric, periodontal, and saliva assessments at baseline, 3 months, and 6 months. They also received standardized oral-hygiene instructions at baseline; no periodontal treatment was provided during follow-up unless clinically necessary.
Participants allocated to NSG received non-surgical management over the same follow-up period and completed anthropometric, periodontal, and saliva assessments at baseline, 3 months, and 6 months. They also received standardized oral-hygiene instructions at baseline; no periodontal treatment was provided during follow-up unless clinically necessary
