Dentists' restorative decision-making and implications for an 'amalgamless' profession. Part 5: knowledge factors

Area of Science:

• Dental Materials Science
• Restorative Dentistry
• Evidence-Based Dentistry

Background:

• Australia is poised to phase down amalgam use following the Minamata Convention ratification.
• Limited research exists on how dentists' knowledge influences decision-making regarding restorative materials.

Purpose of the Study:

• To assess Australian dentists' attitudes towards direct restorative materials.
• To understand factors influencing dentists' decision-making in restorative material selection.

Main Methods:

• An online survey was distributed to members of the Australian Dental Association and the Royal Australasian College of Dental Surgeons.
• The survey explored aspects of and attitudes towards the use of direct restorative materials.

Main Results:

• 408 dentists responded, with 58% noting consistency in undergraduate teaching.
• 52% perceived a gap between undergraduate education and clinical practice.
• Postgraduate education was the primary influence on decision-making, with 96% valuing evidence-based knowledge.

Conclusions:

• Dental schools must update curricula on evolving restorative material technology.
• A disconnect exists between dental education and practical application.
• The evidence base is perceived as complex; clinical guidelines are recommended.
