An analysis of periodontal status in desquamative gingivitis and the correlative factors

To study the clinical periodontal status of patients with desquamative gingivitis (DG) and analyze the factors that influence clinical periodontal indicators.

A purposive sampling method was used to obtain 42 subjects for a DG case group and a control group. Periodontal clinical indicators were detected, and related factors were analyzed.

The DG patients were primarily middle-aged women. Periodontal clinical indicators were more prevalent in individuals with oral lichen planus (OLP) and mucous membrane pemphigoid (MMP) than in the control group. Probing depth (PD) (χ²＝53.058, P<0.001; χ²＝32.989, P<0.001), clinical attachment (χ²＝30.292, P<0.001; χ²＝32.470, P<0.001) and the positive rate of bleeding on probing (BOP) (χ²＝50.003, P<0.001; χ²＝36.236, P<0.001) were higher in the OLP and MMP group than in the control group. The time interval between the onset and treatment of DG was correlated with PD (r_s＝0.523, P<0.001) and the rate of positive BOP sites (r_s＝0.377, P＝0.014).

Patients with DG have obvious periodontal lesions. Early medical intervention is helpful for diagnosing and treating DG-related oral and systemic disease.
