Assessment of knowledge of biomaterial used in periodontics among dentistry students: a cross -sectional study

Abstract

Aim: This study aimed to evaluate the degree of knowledge of biomaterials used in periodontics of dentistry undergraduate students from different semesters and universities in Brazil. Materials and Methods: The sample comprised 210 students from the fifth and tenth semesters of dentistry graduation courses. A two-part (Part I, sociodemographic items; Part II, 15 objective questions about biomaterials used in periodontics) questionnaire survey was conducted using Google Forms. Results: Most participants reported having some knowledge of biomaterials (57%), with 48% stating they had little knowledge. during graduation; were interested in biomaterials; considered feasible the use of biomaterials during the graduation course. Most students considered biomaterial use safe (97%) and specific qualification for biomaterial use to be unnecessary (58%). No statistically significant association was found between sociodemographic factors and the degree of knowledge of biomaterials. Discussion: The opportunity to work with biomaterials during graduation was associated with the degree of knowledge of biomaterials. Most participants did not have the opportunity to work with biomaterials during graduation and considered that they knew nothing or little about biomaterials. Conclusion: Based on the results, we conclude that there is a gap in theoretical and practical knowledge regarding biomaterial use in periodontics in dentistry graduation courses in Brazil.
