Abstract

There is a current trend to restore posterior teeth with composite resin due to increasing demands on natural tooth colour restoration and increased concern about the safety of amalgam restorations. The objective was to evaluate the current teaching of posterior direct restoration among restorative dental lecturers in Malaysia compared to available international literature. An online questionnaire, which sought information on the teaching of posterior restoration was developed and distributed to 13 dental schools in Malaysia. The response rate for the questionnaire was 53.8%. The most popular posterior restoration teaching methods among the respondents were lecture (95.7%), demonstration (87.0%) and problem-based learning (PBL) (73.9%), while continuous assessment and a practical competency test (82.6%) were the most popular assessment methods. Placing a hard setting calcium hydroxide and GIC base for deep cavity restored by composite restoration was taught in 79.2% of cases. The standard protocols for posterior composite restoration were incremental filling in deep cavity (87.5%), using circumferential metal bands with wooden wedge (91.7%), with a total etch system (95.8%), using a light emitting diode (LED) light curing unit (91.7%), finishing using water cooling (80%) and finishing with a disc (87.5%). Graduates from dental schools in Malaysia received similar theoretical, preclinical and clinical teaching on posterior restoration techniques, although there were variations in the delivery methods, techniques and assessments, pointing to a need for uniformity and consensus.

Highlights

Composite resin restoration is one of the dental practitioner choices besides traditional amalgam restoration
The assessments conducted in the dental schools in Malaysia were made up of quizzes, mini examinations, clinical assessments and competency performance assessments designed in accordance with the four levels of Miller’s Pyramid of clinical competence and the affective, psychomotor and affective domains in Bloom’s Taxonomy of theoretical educational framework [29,30,31,32]
It is noteworthy that one of the findings of this study indicated that the conventional teaching of placing a liner underneath an amalgam and composite restoration was considered not unusual in the dental schools in Malaysia

Summary

Introduction

Composite resin restoration is one of the dental practitioner choices besides traditional amalgam restoration. Evidence shows that a well restored composite resin restoration is able to provide a high survival and success rate of the posterior restoration [3,5,6] It is more aesthetically pleasing compared to the traditional amalgam restoration. The current concept of a minimal invasive approach, which focuses more on collaborative work for conservative techniques, and treatment being introduced and advocated worldwide, means resin composites is seen as a more appropriate method. This is because dental amalgam restoration technically requires the removal of unnecessary, yet sound, tooth structure to provide more mechanical resistance and retention features. It is considered less conservative than resin composite restoration [12,13]
