The aim of this study was access the rate of acceptance, anxiety and variation of heart rate (HR), oxygen saturation (SpO2) and both diastolic (DBP) and systolic (ABP) blood pressure with the inhalation sedation using nitrous oxide and oxygen (N2O/O2). Twenty healthful volunteers with average age of 20.55 years old (±2,93 years) undergoing removal of third molars had participated of this study, carried through in 3 phases: A stage sedation with N2O/O2 without surgery; B and C stages - extraction of one of the sides, of random form, with (C-N2O) or without (S-N2O) sedation techinque. The anxiety degree was evaluated by Corah s Dental Anxiety Scale (EADC); the painful sensation during and after the surgery was evaluated by Eleven points in box Scale (EC); e analysis of the degree of acceptance of the volunteer through the subject questionnaire (QS). It was used the test of Wilcoxon and Friedman (α= 0,05) and the answers of QS by explorative analysis. The QS showed that 60% of the volunteers had given maximum note for C-N2O, being 8.75(±1.71) the average. All the volunteers had affirmed that C-N2O was more pleasant. However, 20% of the volunteers had told some adverse symptom in the C-N2O. In relation to the time of the surgery, 15% of the volunteers had considered that the C-N2O was slower, equal 30% and faster 55%, with significant differences between the stages of surgery (p=0.020). The pain story after the C-N2O was lesser or equal for 85% and greater for 15% of the volunteers. The volunteers had moderately revealed anxious in all the phases, without significant difference between them (p=0.229). It did not have difference for pain during surgery (p=0,864) and pain after surgery (p=0.816). The HR presented significant difference enters the stages of surgery (p=0.020) and between phases C-N2O and S-N2O (p=0,000), differently of the SpO2 between phases (p= 0.153), DBP C-N2O and S-N2O before(p=1.000) and after(p=0.730) and of ABP C-N2O and S-N2O before(p=0.350) and after(p=0.975). These results suggest that the volunteers moderately revealed anxious in all the phases, and the C-N2O being most pleasant. The C-N2O reduced the HR significantly, but it did not influence in the ABP, DBP and SpO2. The C-N2O did not modify the pain during and after surgery.
