Preference for using posts to restore endodontically treated teeth: findings from a survey with dentists

Abstract

The aim of this study was to evaluate if clinical experience, whether in relation to length of practice time and/or level of specialization influences the dentist's preference for using posts to restore endodontically treated teeth. A cross sectional study was carried out using a questionnaire with dentists (n = 276) in Pelotas, southern Brazil. Data were collected regarding clinical experience, post-graduate training, and variables related to restorations (posts/cements and use of rubber dam) for endodontically treated teeth. The data were submitted to a descriptive analysis and associations were tested. The response rate was 68%. Cast metal posts (24.53%), glass fiber posts (20.75%) and resin cement (66.67%) were the most commonly selected materials. In relation to rubber dams, 93.05% of the dentists were found not use them to lute posts. There was a significant association between the level of training of post-graduate dentists and the type of post used (p = 0.027), in that dentists without post-graduate training used cast metal posts more frequently, whereas dentists with post-graduate training reported glass fiber posts as their first choice. The results of the study showed that dentists preferred cast metal posts, glass fiber posts and resin cement. Continuing education influenced the decision of the dentists on their choice of dental posts.

Knowledge and attitudes of students and dentists about the use and cementation of intra-radicular posts

“…These findings corroborate previous findings showing that cast metal posts are still used for dentists [11]. It is obvious that cast metal posts are the gold standard in literature to restore ETT with large coronal destruction as they present high success rates in longitudinal studies [16,19].…”

“…The results of this study showed a difference in the choices of materials/techniques to restore ETT between dentists and students. Literature has shown that some factors could influence the choices of materials and techniques as workplace, time since graduation, post graduate training and capability to keep updated [9][10][11]13].…”

“…Furthermore, students could have a better understating of new possibilities of dental materials and techniques since they are in contact with the academia. However, the literature shows that the level of training of dentists can influence the clinical choices and, consequently, their practices [9,11,18].…”

“…Although dentists are expected to present better technical skills compared to students, some factors could influence the choices and longevity of materials/techniques such as workplace, time since graduation, post graduate training and capability to keep updated [9][10][11]. Nevertheless, and from the best of our knowledge, there is no report in the literature about the association between the knowledge about the use of intraradicular posts and cementation techniques of dental students and dentists.…”

Influence of Eugenol-based Sealers on Push-out Bond Strength of Fiber Post Luted with Resin Cement: Systematic Review and Meta-analysis

“…These posts require adequate luting material to achieve successful clinical performance, and the use of resin-based luting agents has increased over the last decades (4). When eugenolbased sealers are prepared, eugenol is mixed with zinc oxide in the presence of water, and a chelation reaction occurs, resulting in a zinc eugenolate matrix with unreacted eugenol molecules trapped inside.…”
