Assessment of dental students’ and dentists’ knowledge of post and core technique use in endodontically treated teeth

Restoring the morpho-functionality of a dental crown that shows extensive surface and depth lesions can be achieved by means of prosthetic therapy represented by different post and core techniques. Purpose The present study aims to assess dental students’ and dentists’ knowledge of post and core techniques using a questionnaire. Material and methods. For this survey-based study a questionnaire was designed consisting of 15 questions related to the category of participants, questions related to the sources of information and questions related to the topic discussed. Results. This study included 55 participants including 39 students in years IV, V and VI, and 16 dentists. Of the 55 participants, 44 were in the 20-29 age group, 10 in the 29-39 age group, and 1 participant was over 40 years old. In terms of gender, 43 were females and 12 males. 74.5% of the participants (n=41) thought that prefabricated fiberglass posts are most often used, followed by cast metal posts, mentioned by 58.2% (n=32) of the respondents. 81.8%(n=45) of the respondents specified intra-radicular aggregated metal-ceramic crowns as the most used substitution method. Conclusion. Based on the results of the study, it can be concluded the main types of prefabricated posts used in post and core techniques were: fiberglass posts and screwed metal posts.
