Objective:
A survey was undertaken to categorize the materials used for the restoration of endodontic access openings through complete-coverage crowns after completion of nonsurgical root canal treatment.
Method And Materials:
The survey package consisted of a cover letter stating instructions, rationale, and purpose for the questionnaire, a questionnaire of 8 short-answer questions, and a stamped, self-addressed envelope. A randomized sample of active dentists (300 general practitioners, 300 prosthodontists, and 300 endodontists), was selected. Collected data were analyzed with the chi-square analysis.
Results:
Most general practitioners (93%), endodontists (61%), and prosthodontists (75%) reported that they frequently or always permanently restore teeth after nonsurgical root canal treatment. Empress was the all-ceramic system used most commonly by prosthodontists (42%) and general practitioners (38%). A statistically significant difference in restorative material preference was found (P < 0.0001), depending on the type of crown used.
Conclusion:
Amalgam alone and in combination with bonding agents are materials of choice for restoration of access openings through all-metal complete crowns, while resin composite is the choice for all types of complete crowns involving porcelain. Endodontists preferred "other" materials.
