BACKGROUND: Mucous membrane pemphigoid (MMP) describes an autoimmune disease with a range of variants, including those with oral, ocular, and cutaneous lesions. Persistent oral lesions, lack of effective oral hygiene, and plaque accumulation may increase the risk of long-term periodontal disease. However, to our knowledge, no studies have evaluated the relationship between the presence of gingival MMP and periodontal health. The purpose of this study was to evaluate the possible impact of gingival pemphigoid lesions on the human periodontium. METHODS: Twenty patients with histologic confirmation of subepithelial separation with or without direct immunofluorescence testing were randomly chosen to participate in a study evaluating their periodontal status. Parameters evaluated included plaque score, gingival index, bleeding index, probing depths, recession, clinical attachment level, mobility, furcation involvement, number of missing teeth, and Machtei criteria, a previously defined criteria for periodontitis. Individuals matched with respect to age, gender, and smoking history were selected and evaluated for the same parameters. RESULTS: MMP patients had statistically significant larger mean gingival index scores than age, gender, and smoking history matched controls. Plaque scores, bleeding index, mobility, furcations, clinical attachment level, recession, and periodontal status did not show statistically significant differences between MMP and control patients. A statistically significant difference in plaque index was found when patients with MMP in treatment were compared to patients with MMP in remission. Among patients with MMP, those diagnosed >5 years in the past had statistically significantly greater Class I furcation involvement and recession on facial and lingual surfaces of teeth. CONCLUSIONS: A relationship was found to suggest that patients with MMP exhibit more gingival inflammation than a control population. Among patients with MMP, patients currently in treatment have higher plaque indices than those in remission and not receiving treatment. Furthermore, when comparing patients with MMP who received a diagnosis>5 years in the past to those with a diagnosis in the past 5 years, statistically significantly greater Class I furcation and facial and lingual recession were measured. Long-term follow-up in this population may provide additional information as to periodontal progression in MMP versus control patients.
