About this study
Official title: Amalgam Restorations Teaching in Pediatric Dentistry in Egyptian Universities: A Cross-sectional Study
To assess the pediatric dentistry educator's perception about teaching and using dental amalgam as restoration for primary teeth.
Read the detailed description
Dental education has long emphasized the development of clinical skills necessary for restorative procedures. Among these, amalgam restorations have been a foundational component of dental curricula for decades due to their durability, cost-effectiveness, and historical prominence in restorative dentistry. However, in recent years, the use of amalgam has become a subject of debate due to environmental concerns related to mercury content, alongside the increasing popularity of composite materials.
To our knowledge no current data is available regarding teaching amalgam in pediatric dentistry in Egyptian dental universities. So, the aim of this study is to assess the pediatric dentistry educator's perception about teaching and using dental amalgam as restoration for primary teeth. This could help in making improvements to the dental education system ensuring that future dentists are equipped to offer patients the best treatment options based on individual needs, improving overall oral health outcomes.
