Introduction: Endodontic is one of the difficult branches in dentistry as it requires special skills to deals with treatment of the root canals. These difficulties comes from anatomical complexities of the roots, working area is very limited, and clear and clean area before final obturation is required which is difficult to achieve. In addition, complications and subsequent retreatment are difficult and are time- and materials-wasting. Methods: A self-administrated questionnaire was distributed to intern dentists at all dental school all around the Kingdom of Saudia Arabia. It consisted of 10 questions related to all possible procedures in endodontic treatment. The confidence level was scored in 5-points Liker scale ranging from 1 “very little confidence" to 5 “very confident". Data were analyzed using SPSS V22 software program. A p-value < 0.05 was considered significant.
Results: Thirteen different dental schools from 13 different universities including 230 intern dentists were included in the analysis. Number of the included interns varied considerably between universities. The largest number of participants were from King Khalid University with 47 interns (18.7%) and the least number of participants were from Alfarabi College and Majmaah University with 9 interns, equally. Most participants were confident or very confident of most of the endodontic procedures. More than two thirds (71.74%) of participants had no experience in removing broken instruments from root canals. About 19.57% of participants also had no experience in performing retreatment of failed RCT. Twenty eight (12.17%) participants had very little confidence regarding using rotary instruments. Less than one third (29.13%) of participants were confident regarding irrigation of root canals. Only three questions had significant differences in means between universities. With regard to gender, no significant differences were found in relation to all confidence questions.
Conclusion: Level of confidence regarding endodontic treatment among intern dentists in Saudia Arabia is acceptable. More practical training, however, for the most difficult procedures are highly recommended.
