Abstract
OBJECTIVE: The objective of the study is to evaluate differences in treatment philosophy, material choice, and techniques among dentists based on: age and number of years in practice; qualification and specialization; region from which specialty education was received: North America, Europe, MENA, Asian sub-continent, other.
MATERIALS AND METHODS: A questionnaire which contained 5 questions regarding general data about the responders, 8 questions regarding philosophies and techniques of complete-coverage restorations over natural teeth and implants and 9 questions regarding philosophies and techniques of restoring endodontically treated teeth was prepared. This questionnaire was hand-distributed to a random sample of licensed 100 general practitioners and 30 prosthodontists in Dubai, UAE. Data were analyzed by calculating the Chi-square statistic for each variable using SPPS version 13.O statistical software.
RESULTS: A total of 82 usable questionnaires were returned, giving a response rate of 75%. Coronal coverage was considered essential for ETT anterior (38%) and posterior (74%) teeth. Splinting of adjacent crowns on natural teeth was done by 17% of the dentists. Implant dentistry was not practiced by 26% of practitioners and the majority of the remaining dentists preferred to use cement-retained implant restorations (80%). Monolithic ceramic materials (64%) were preferred for anterior teeth crowns while PVZ crowns were popular for premolar (45%) and molar (40%) teeth. Gingival retraction methods were considered essential for regular usage by 51% of the dentists and gingival retraction cords (70%) were the most commonly used method. Resin cement (57%) was popular for cementation of all-ceramic crowns while GIC (49%) was the preferred cement for PFM crowns. The majority of the dentists (88%) did not believe that every ETT must receive a post though 50% of the dentists believed that a post will reinforce an ETT. A ferrule was considered essential by 80% of the dentists and 62% of the dentists used auxiliary procedures to establish a ferrule when absent. Prefabricated posts were preferred for all teeth over cast post and cores and fiber reinforced posts (41%) were the most popular. Composite resin (73%) was the most preferred core build-up material and GIC (38%) and resin cement (32%) were most commonly used for cementation of the post.
CONCLUSIONS: Philosophies and techniques of coronal coverage and treatment of endodontically treated teeth varied significantly with the dentists experience, qualification and region of education.
