The statistical sample was selected by available sampling method including all dentistry students in fifth and sixth years (n=27) studying in the School of Dentistry, Hamadan, residents (n=10) and specialists in endodontics (n=10) who answered randomly researcher-made questionnaire questions on stress at different stages of root surgery. Stress among students is higher than root residents and specialists, except for 3 cases that specialists' stress is higher than other groups including stress due to work on mandibular anterior teeth, premolar teeth on the lower jaw and pulp and periodontal injection. For intergroup comparison of specialists, the highest stress is related to prepare access cavity in special cases. For intergroup comparison of residents, the highest stress is related to treat patients with systemic problems. For intergroup comparison of students, the highest stress is related to work on maxillary molar teeth. To determine the lowest and highest stress between the three groups, the highest stress of root canal therapy is related to work on maxillary molar teeth. The lowest stress from respondent groups' view is related to anesthesia and lidocaine injection. According to the study results, stress due to root canal therapy in dentistry specialists, residents and students is less than average.
