Malocclusion, tooth decay and gingivitis as factors associated with the shame of smiles in oncology pediatric patients

Abstract

The study aimed at explaining the “shame to smile” in oncologic pediatric patients, considering variables related to malocclusion, tooth decay and periodontal disease. This is a cross-sectional research, conducted in a reference hospital in the state of Paraíba. The sample was taken by convenience, and composed of 52 patients aged 12 and from 15 to 19 years old. Two forms were used as data collection instruments (clinical exam and interview), both from the program Saúde Bucal Brasil 2010. The research was conducted between 2011 and 2014. Data were analyzed through the software R (version 3.1.1), using descriptive and inferential statistical techniques. In the descriptive analysis, absolute and percentile values, as well as central tendency and dispersion measures were used. In the inferential analysis, through the logistic binary regression, the significant variables to explain the inhibition of smiling presented by the patients of the study could be identified. Risk factors for such an inhibition were: maxillary misalignment (OR-6.59), altered molar relation (OR=9.16), number of teeth with cavities (OR=1.71) and the presence of gingival bleeding (OR=15.88). Malocclusion, tooth decay and gingivitis are factors associated to smile inhibition in pediatric oncological patients.
