(PR101) Bioceramic Root Canal Sealer Use: A Survey of Predoctoral Endodontic Programs at U.S. and Canadian Dental Schools

The incorporation of bioceramic material into root canal sealers has received considerable attention in the past decade because simplifying the obturation treatment phase perhaps improved outcomes. The objective of this study was to determine the incidence and rationale of using these new proprietary root canal sealers by dental students at US and Canadian dental schools.  An anonymous, seven to ten question Qualtrix survey was sent to predoctoral endodontic program directors at US and Canadian dental schools.  The response rate was 43% (30 out of 69).  46% of respondents reported using a bioceramic sealer. The biologic and physical-chemical properties was the most common rationale for use, followed by outcome studies, or a combination of both.  Regarding the accompanying obturation technique, 45% reported using a single cone technique.  Of the bioceramic sealer users, 72% were pleased with the sealer thus far. However, two concerns expressed by users were increased number of overfills/sealer puffs and lack of knowledge regarding retreatment. The use of bioceramic sealers with a single cone technique is increasing in predoctoral dental clinics in US and Canadian dental schools. These study results enable the dental profession to better understand the acceptance of bioceramic sealers for routine endodontic treatment.
