Abstract

The study was carried out on 40 teeth with metal crowns indicated at the Department of Odonto-Stomatology - Hanoi Medical University Hospital and A7 High-Tech Center for Odonto-Stomatology, School of Dentistry, Hanoi Medical University from September 2015 to September 2016. Objectives: To describe the clinical and radiographic characteristics of molars with indications for restoration by Ceramage fused to metal crowns. Methods: a cross-sectional study. Results: 39/40 molars caused by caries or pulp disease were well treated and were covered with a crown, accounting for 97.5%. Only 1 heavily eroded tooth with viral pulp was taken, accounting for 2.5%. 55% of molars have 4 walls left after preparation, 42.5%, 2.5% of molars had 3 and 2 walls, respectively. 22 molars (55%) still had 4 walls after preparation, no need to plug the root canal post. Of the 17 molars with 3 remaining walls after preparation, there were 4 teeth with root canal posts, 1 tooth with 2 walls had root canal posts after preparation. The percentage of teeth that did not need to be placed posts to the root canal was 35 teeth, accounting for 87.5%. Conclusion: The main reason for the restoration was due to tooth decay, pulp disease (97.5%), mostly the first permanent molars, the teeth after preparation still had enough 4 walls and without post placement accounts for 55%, 3 walls accounts for 42.5% and 2 walls accounts for 2.5%, which needed to be placed by posts and reconstructed before taking impressions.
