Clinical evaluation of amalgam restorations

Area of Science:

• Dental materials science
• Clinical dentistry
• Restorative dentistry

Background:

• Established clinical evaluation systems for dental restorations exhibit good reproducibility.
• However, existing systems may not be sensitive enough to detect subtle differences in amalgam restorations.

Purpose of the Study:

• To develop and evaluate a modified clinical evaluation system for dental restorations.
• To assess the system's suitability for detecting minor differences in amalgam restorations.

Main Methods:

• A modified evaluation system, incorporating additional characteristics, was developed based on existing principles.
• The modified system was applied in practice to assess 246 amalgam restorations by two examiners.

Main Results:

• The modified system achieved approximately 70% agreement between examiners after an initial training period.
• The study highlighted the necessity of examiner calibration and precise criterion definitions.

Conclusions:

• The modified clinical evaluation system shows potential for improved assessment of amalgam restorations.
• Standardized training and clear guidelines are essential for consistent and reliable clinical evaluations of dental restorations.
