Abstract: Objective: To investigate the association among gingival enlargement (GE), gingivitis and social backgrounds in subjects undergoing fixed orthodontic treatment. Methods: A total of 250 patients undergoing fixed orthodontic treatment were divided into two groups including6-12months treatment group and more than 12months treatment group. The patient was examined by a single calibrated examiner for plaque and gingival indexes, probing pocket depth, clinical attachment loss, and gingival enlargement. Social background, orthodontic treatment duration, and use of dental floss were assessed by oral interviews. Associations were assessed by means of Poisson’s regression models. Results: The presence of gingival bleeding (RR 1.02; 95% CI 1.01-1.02) and excess resin around brackets (RR 1.04; 95% CI 1.04-1.05) were associated with an increase in GE. No association was found between socio-demographic characteristics and gingival enlargement. Conclusion: Anterior gingival bleeding and excess resin around brackets were associated with higher level of anterior gingival enlargement in subjects under orthodontic treatment.
