Dental treatment is considered a generating condition of stress and anxiety, especially when it comes to childcare. Feelings like anxiety can alter the levels of blood oxygenation from individuals in different situations, like during dental treatment. This cross over trial aimed to analyze the use of music as a distraction resource during children dental treatment, evaluating their cardiac frequency and saturation of oxygen (SpO2). Thirty-four children took part in this study, from 4 to 6 years old, with no previous dental experience, who had two carious lesions on occlusal surfaces of molars, from the municipalities of Confins and Brumadinho, southeast Brasil. Children were selected through oral clinical exams, conducted in public schools. After parents signed a written consent; children were allocated in two groups: treatment with music (G1) and treatment without music (G2). Children acted as controls of themselves: the cross between groups allowed all children to be treated with and without music. Three dental visits were, scheduled in a weekly basis, the first for anamnesis and clinical examination; the second and third for the modified atraumatic restorative treatment (ARTm). The Wolfgang Amadeus Mozart Symphony No. 40 in G minor K550 was played in headphones. Cardiac frequency and saturation of oxygen were obtained using a pulse oximeter, in the kids index finger, with the measures being taken in three moments: in the beginning of the treatment, during the intervention (use of a rotating device) and at the end of the treatment. Data were compiled and analyzed through the statistic software SPSS, version 21.0. The Wilcoxon test was used for inter and intra groups comparison (p<0,050). Eighteen girls (53%) and sixteen boys (47%) with the average age being about 5,54 (DP=0,647) years old took part on the trials. Most children had never heard classical music before (79,4%) by the end of treatment they reported pleasure hearing music during dental treatment. G1 group showed significant reduction in saturation of oxygen during the intervention in visit 2 when compared with visit 3 (p=0,045). Music worked as a reassuring instrument during children dental treatment.
