A comparison of two methods for evaluating primary class II cavity preparations

Area of Science:

• Dental Education
• Clinical Evaluation
• Pediatric Dentistry

Background:

• Traditional global (glance and grade) methods for evaluating dental cavity preparations lack detailed feedback.
• Assessing the quality of class II cavity preparations in primary teeth is crucial for effective dental education.

Purpose of the Study:

• To develop and test an analytical system for evaluating class II cavity preparations in primary teeth.
• To compare the reliability of the analytical system against the traditional global evaluation method.

Main Methods:

• An analytical system with a 5-point rating scale for 10 performance criteria was designed.
• Fifteen examiners evaluated 24 class II cavity preparations in simulated primary teeth.
• Intraexaminer and interexaminer reliability were assessed for both methods.

Main Results:

• The analytical system demonstrated improved interexaminer reliability compared to the global method.
• The analytical system facilitates enhanced student feedback and learning opportunities.

Conclusions:

• An analytical system can improve the reliability of evaluating class II cavity preparations in primary teeth.
• This system offers a more structured approach to assessment and educational feedback in pediatric dentistry.
