Background: Dental anxiety and fear appear to vary according to the type of treatment. Endodontic treatments have been shown to cause higher levels of anxiety than restorative or prophylactic treatments. Patient's pretreatment decisions and post-treatment satisfaction may be strongly influenced by social, psychological, and behavioral aspects including knowledge, beliefs, attitudes, preferences, and behaviors. Aim: This study aimed at investigating the percentage of patient's satisfaction toward the endodontic treatment done by endodontic specialists. Methodology: Some cases (78) from different ages were asked to apply a questionnaire to show the percentage of satisfaction toward endodontic treatment of patients received by endodontic specialists during the year of 2017 in Saudi Arabia. Results: percentage of satisfaction was different among the cases toward the various steps in endodontic treatment, but it was evident that more satisfaction was related to qualitative and proper treatment procedure but the correlation between satisfaction and pain score was negative. Conclusion: Patients satisfaction toward the endodontic treatment is related to different factors, some of these factors related to the patient himself like his health status and the others depend on the nature of endodontic procedure itself.
