Alternatives for vital pulp therapy for dentin-pulp complex repair of primary teeth This thesis aimed to present two scientific papers. In the Article 1, the objective was to evaluate the knowledge of students and professionals on selective caries tissue removal and in Article 2, the objective will be to present the protocol of a new dentinpulp biostimulation material. In the Article 1, the sample included students from the 3rd and 4th year of a Dental School (Group 1) and professionals from a Hospital Dental Center (Group 2). An anonymous, confidential, validated, and translated questionnaire containing eleven questions including questions about therapeutic attitudes, diagnosis, and behavior towards deep carious lesions was applied to participants. The data collected were analyzed using the Chi-square test and multivariate logistic regression (p<0.05). In the Article 2, the sample will select 124 teeth of children between 5 and 9 years old, of both genders, who present deep caries lesions with pulp involvement and without periapical lesion. The teeth will be divided between Group 1-Mineral Trioxide Aggregate (MTA) and Group 2-Binding of dentin/pulp biostimulation (BBio). Clinical and radiographic analyzes will be performed at 6-and 12-months post treatment. The dentin barrier thickness will be checked using Image J2 software. The chi-square test and t-test were used in the statistical analysis (p<0.05). For Article 1, the results showed that in the total study sample (n=146), 81.51% were female, 52.05% Group 2 and the prevalent age of the interviewees was between 18 and 29 years old (85.62%).
