Plaque retention on teeth restored with full-ceramic crowns: a comparative study.

Area of Science:

• Dental Materials Science
• Biomaterials
• Restorative Dentistry

Background:

• Plaque accumulation on dental restorations is a significant factor in oral health.
• Different restorative materials vary in their susceptibility to plaque retention.
• Understanding plaque retention is crucial for selecting appropriate prosthetic materials.

Purpose of the Study:

• To compare the plaque retention of full-ceramic crowns with other common dental restorative materials.
• To evaluate the influence of material type on soft debris accumulation.
• To determine the relationship between ceramic surface area and plaque retention.

Main Methods:

• Plaque accumulation was assessed using the Silness and Löe plaque index.
• 150 crowns across 19 patients were evaluated.
• Individual crown plaque indices were compared to quadrant plaque indices (100% baseline).

Main Results:

• Cerestore full-ceramic crowns exhibited the lowest plaque retention (32%).
• Plaque retention increased with ceramometal crowns (90%), natural teeth (110%), cast gold (148%), and acrylic resin veneer crowns (152%).
• A larger ceramic surface area correlated with decreased plaque retention.

Conclusions:

• Ceramic materials demonstrate superior cleanability and low plaque retention.
• Full-ceramic restorations are advantageous in minimizing plaque accumulation.
• Material choice significantly impacts plaque retention on dental prosthetics.
