Dental procedures involve high situation of stress and anxiety. Objectives: To verify an association of dental anxiety measured by Modified Dental Anxiety Scale (MDAS), with variations of salivary cortisol (sC) and salivary α-amylase (sAA) levels in patients undergoing third molar surgery. Materials and Methods: Thirty two patients were selected in Clínica Odontológica of Faculdade de Odontologia, Universidade de São Paulo. MDAS was accomplished in first query. Saliva samples were collected during interview, on surgery day and postoperative follow-up visits at intervals of one week at the same hour. Three patients classified as anxious, and four who reported prior traumatic event were gathered in a group. Results: There was no difference between this group and the non-anxious group when comparing gender and pain. sC levels (KW, p = 0.65) and sAA (KW, p = 0.69) on three days weren’t different in relation to gender. Levels of sAA increased in day surgery when comparing anxious/ event and non-anxious patients, while sC levels were higher during interview and postoperative follow up. Conclusion: Dental anxiety and previous dental traumatic event showed marked production of sC and sAA levels in relation to their counterparts in this situation. Subjective and objective dental anxiety relationship needs further investigations.
