Abstract

Abstract: Introduction: Objective parameters may help the decision of how to manage existing dental restorations in patients.

Objective: This study tested the following hypotheses: i) teaching objective criteria to dental students enhances their criticism toward the indication for replacement of dental restorations; and ii) a complementary practical approach enhances the proportion of correctly indicated treatments compared with a strictly theoretical approach.

Method: This block-randomized controlled trial involved dental students from a Brazilian university who were randomized to either a didactic/theoretical class group (A, control) or a didactic/theoretical class followed by practical training (group B); both conditions were applied in a moodle-based environment. The proportion of correctly indicated interventions before and after teaching the criteria was compared with using Mann–Whitney U-test (p<0.05), and a comparison between the approaches was established with Wilcoxon test (p<0.05).

Result: The baseline proportion of correct assignments significantly increased after interventions for both groups (p=0.02), with no significant difference between the interventions (p=0.871).

Conclusion: The proposed online training enhanced the proportion of correct assignments to restorations, confirming the first study hypothesis. The second hypothesis was rejected because differences between the strategies had no effect on the proportion of correct answers. Focusing on teaching objective criteria for assessment of the quality of restorations would enhance students’ ability to correctly treat them.

Resumo

Resumo: Introdução: Parâmetros objetivos podem auxiliar a decisão de como lidar com restaurações existentes em pacientes.

Objetivo: Este estudo testou as hipóteses que seguem: i) o ensino de critérios objetivos a estudantes de odontologia melhora sua crítica acerca da indicação para substituição de restaurações; e ii) uma abordagem prática complementar aumenta a proporção de tratamentos indicados corretamente comparada com uma abordagem estritamente teórica.

Método: Este ensaio randomizado em bloco controlado envolveu estudantes de odontologia de uma universidade brasileira que foram randomizados para um grupo que recebeu uma aula teórica (A, controle) ou uma aula teórica seguida por um treinamento prático (grupo B); ambas as intervenções foram aplicadas em um ambiente moodle . A proporção de restaurações indicadas corretamente antes e depois do ensino dos critérios foi comparada com o teste U de Mann-Whitney (p<0,05), e a comparação entre as intervenções foi estabelecida com o teste de Wilcoxon (p<0,05).

Resultado: A proporção de indicações corretas aumentou significativamente após as intervenções para ambos os grupos (p=0,02), sem diferença significativa entre as intervenções (p=0,871).

Conclusão: O treinamento online proposto aumentou a proporção de indicações corretas às restaurações, confirmando a primeira hipótese do estudo. A segunda hipótese foi rejeitada visto que as diferenças entre as intervenções não tiveram efeito na proporção de respostas corretas. O foco no ensino de parâmetros objetivos para avaliação da qualidade das restaurações pode aumentar a habilidade dos estudantes de tratá-las corretamente.
