Contour of class V composite restorations.

Area of Science:

• Dentistry
• Dental Materials Science
• Restorative Dentistry

Background:

• Reproducing natural tooth contours in Class V composite restorations is challenging.
• Effective matrix systems are essential for achieving optimal aesthetic and functional outcomes.

Purpose of the Study:

• To evaluate the effectiveness of different matrix techniques in achieving natural tooth contours for Class V composite restorations.
• To identify matrix systems that produce superior results in restorative dentistry.

Main Methods:

• Comparison of various matrix techniques, including compound index with plastic sheath/Mylar strip and composite instruments with/without alcohol.
• Qualitative assessment of the reproduced tooth contours.

Main Results:

• The compound index technique, utilizing a plastic sheath or Mylar strip, resulted in the best tooth contours.
• Matrix techniques employing the composite instrument, with or without alcohol, yielded the poorest contours.

Conclusions:

• Matrix selection significantly impacts the contour accuracy of Class V composite restorations.
• The compound index with a plastic sheath or Mylar strip is recommended for optimal contour reproduction in Class V restorations.
