Background: Idiopathic gingival enlargement is associated with plaque, but other contributing factors are unclear. The prognosis of idiopathic gingival enlargement is closely related to the patient's oral hygiene habits and regular follow-up.
Case presentation: This article reports a case of a 32-year-old male patient with idiopathic gingival enlargement. The patient presented to the department of stomatology with a 2-month history of gingival swelling and pain on the right upper posterior teeth. During the treatment, oral hygiene instruction, supragingival cleaning, subgingival scaling, and root planning were carried out, and part of the hyperplastic gingiva was taken and sent for pathology. Pathological examination showed gingival enlargement with chronic suppurative inflammation. At 4-month follow-up, the patient's periodontal condition remained basically stable, and the gingival enlargement did not recur.
Conclusion: The treatment of this case resulted in significant reduction of gingival swelling and patient's pain reduction through non-surgical treatment and good plaque control, indicating that patients with idiopathic gingival enlargement can also achieve ideal results through non-surgical treatment. Through oral hygiene instruction, the patient mastered the method of self-plaque control, which is conducive to the long-term stabilization of the periodontal situation.
