Abstract
Amalgam has historically been a widely used restorative material for posterior teeth, valued for its longevity. However, concerns about mercury-related health risks and aesthetic drawbacks have led to a decline in its usage. This study aimed to assess the knowledge, attitudes, and practices of dental students, interns, and practicing dentists regarding dental amalgam in dental institutions in western Libya. A cross-sectional survey was conducted with 409 participants, including dental students, interns, dental officers, and faculty members. The questionnaire consisted of 18 questions related to the knowledge, utilization, and safety of dental amalgam. Data analysis using SPSS version 27 revealed that most participants rarely used amalgam, influenced by aesthetic concerns and patient preferences. There was a clear preference for composite resin as an alternative restorative material, indicating a trend towards discontinuing amalgam due to safety and environmental issues. The study concluded that most respondents rarely use dental amalgam, primarily due to aesthetic considerations, patient preferences for tooth-colored materials, and increased awareness of mercury toxicity.
