Abstract:
Objective :To investigate the pathogenic factors and clinical manifestations of contact stomatitis, and to provide references for its clinical diagnosis and prevention.
Methods:The data of 55 subjects with contact stomatitis were analyzed retrospectively, including age, gender, pathogenic factors, type of lesions and site of occurrence.
Results:Among the 55 patients, contact stomatitis occurred at all ages, 19 were male, 36 were female, and the ratio of males to females was 1∶1.89. Among 55 patients, 78.18% (43/55) were caused by oral mucosal contact with dental materials: amalgam fillings accounted for 52.73% (29/55), metal crowns accounted for 9.09% (5/55), removable denture plastic bases accounted for 9.09% (5/55), resin fillings accounted for 5.45% (3/55), and alginate impression materials accounted for 1.82% (1/55); 21.82% (12/55) were caused by oral mucosal contact with food and daily necessities. The clinical manifestations of contact stomatitis include lichenoid reaction, erythema and erosion. The most common site of contact stomatitis was the cheek, followed by the tongue, and the lips, and the gingival and palatal areas were relatively rare. In the buccal mucosa, the incidence of lichenoid reaction was 55% (22/40), which was higher than that of erosion (20%) and erythema (25%), and the difference was statistically significant (P < 0.05). For tongue, lip, gingiva and palate, there was no significant difference in the incidence of the three lesion types（P > 0.05）.
Conclusion:Contact stomatitis occurred at all ages, and there are more female patients than males with contact stomatitis. Dental materials, especially metal and acrylic materials (such as the plastic base of removable dentures, resin fillings, adhesives, and self-setting plastics), are the main pathogenic factors. In buccal mucosa, the incidence of lichenoid reaction is higher.
