Summary
This study compared the time needed for dental restoration placement in children. Composite resin restorations for permanent molars took 35% longer than amalgam restorations.
Area of Science:
- Dentistry
- Dental Materials Science
Background:
- Accurate measurement of chairside time is crucial for dental practice efficiency.
- Understanding time differences between restorative materials aids clinical decision-making.
Purpose of the Study:
- To develop an indirect method for measuring dental restoration placement time.
- To compare operator time for amalgam versus composite resin placement in primary and permanent molars in children.
Main Methods:
- Forty children aged 7-9 years received either amalgam or experimental resin restorations.
- Restorative procedures were videotaped for time analysis.
- Ninety-six restorative procedures were reviewed to evaluate time requirements.
Main Results:
- Class I permanent molar composite restorations required 35% more insertion and finishing time compared to amalgam.
- The study established an indirect method for measuring restoration placement time.
Conclusions:
- Composite resin placement in permanent molars demands significantly more operator time than amalgam.
- The indirect measurement method provides valuable data for assessing chairside efficiency in pediatric dentistry.
