Associação entre a escolha de retentores em dentes tratados endodonticamente e o grau de treinamento do profissional

Abstract

This study assessed the knowledge and attitudes of graduate students and professionals on the use of retainers and luting agents. This cross-sectional study interviewed 150 undergraduate dental students and 150 dentists in the city of Pelotas, using a questionnaire. The questionnaire contained multiple-choice questions on used retainers choice/cement, degree of confidence to use glass fiber posts and resin cement in anterior and posterior teeth with large coronal destruction. Data were analyzed using descriptive analysis and tested combinations through Fisher's Exact test or chi-square with a significance level of 5%. The data about the use of glass fiber post and resin cement confidence level was ranked and submited to the T test. Eighty-seven percent of professionals and 51% of students had used retainers (P=0.00). For anterior teeth (P=0.00), dental students would mostly use glass fiber posts as the first choice, while for posterior teeth, cast metal cores (P=0.004). Regarding the type of cement to lutel cast metal posts, zinc phosphate was selected among dentists and students. As for glass fiber posts, professionals and students chose the self-adhesive resin cement. Public service dentists preferred glass fiber posts for anterior (P=0.023) and posterior teeth (P=0.00), while in the private service cast metal posts were selected. The clinical choices of dentists and students was related to their training level and type of service.
