Direct restorative materials use in Australia in 2002

Area of Science:

• Dental Materials Science
• Clinical Dentistry
• Health Services Research

Background:

• Understanding dentists' material selection is crucial for dental practice management and patient care.
• Amalgam and resin composite are primary restorative materials with distinct properties and applications.

Purpose of the Study:

• To investigate the factors influencing Australian dentists' choices between amalgam and resin composite materials.
• To assess the current usage patterns and perceived impact of these materials in dental practice.

Main Methods:

• A random sample of 1000 Australian dentists received a mailed questionnaire.
• The questionnaire aimed to gather data on material selection criteria and usage frequency.
• 560 responses were analyzed to determine influencing factors and trends.

Main Results:

• Clinical indication (99%) and patient aesthetic demands (99%) were the leading factors in material choice.
• Resin composite usage varied, with 73% of dentists placing large restorations in molars.
• A significant majority (59%) reported decreased amalgam use; 68% felt its discontinuation limits treatment options.
• Increased composite use was associated with higher oral healthcare costs (75%).

Conclusions:

• Australian dentists' material selection is heavily influenced by clinical necessity and patient desires for aesthetics.
• The trend towards composite materials raises concerns about treatment limitations and overall healthcare expenditure.
