Gingival enlargement (GE) can be caused by inflammation, medications, or systemic conditions. Diseases such as hypertension and diabetes have a reciprocal relationship. This case report aims to discuss the clinical effectiveness of conventional gingivectomy in an orthodontic patient with undiagnosed type 2 diabetes. A 37-year-old female patient who had been undergoing orthodontic treatment for 2 years presented with complaints of swollen gums in the anterior region of the lower jaw that frequently bled while brushing her teeth over the past ±1 year. The patient denied persistent pain, uncontrollable bleeding, or a history of other systemic diseases. A general examination revealed a random blood glucose (RBG) level of 272 mg/dL, indicating uncontrolled diabetes with normal blood pressure. An intraoral examination showed gingival enlargement in the anterior mandibular region, particularly around tooth 33, accompanied by plaque and calculus. After blood glucose levels were controlled, conventional scalpel gingivectomy and gingivoplasty were performed. The gingival tissue appeared to cover nearly half of the tooth crown with a gingival overgrowth index of 2, leading to plaque accumulation and aesthetic concerns. The procedure was performed to remove excess gingival tissue, improve gingival contour, reduce plaque accumulation, support orthodontic treatment, and address the patient’s aesthetic concerns. Conventional gingivectomy has proven effective in managing gingival overgrowth when performed according to indications.
