Abstract

This prospective, randomized, parallel study analyzed the color change, tooth sensitivity, degrees of cooperation, and satisfaction of volunteers when submitted to at home dental bleaching with 10% carbamide peroxide (Opalescence -Ultradent Products, Inc. South Jordan, USA) for 21 consecutive days for 2, 4 and 8 hours/day. The wear time of acetate trays/dental bleaching was measured through a TheraMon microsensor (TheraMon® microelectronic system; Sales AgencyGschladt, Hargelsberhg, Austria). Sixty six volunteers, both sexes, with ages ranging from 18 to 22 years were selected and randonly distributed into 3 study groups (n=22). The volunters received information about presence of the microsensor in their trays. The fator studied was the wear time of the trays in three levels: during 2 (GI), 4 (GII) and 8 (GIII) hours/day. For the clinical analysis the response variables were: the degree of daily cooperation of the volunteers as the wear time/daily of the trays, microelectrically collected by micro sensor TheraMon®; the degree of satisfaction of volunteers with dental bleaching; the effectiveness of dental bleaching in the upper and lower incisors and canines teeth, by the visual method (Vita Classical) and digital (Vita Easyshade) and dental sensitivity was evaluated by the volunteers with a scale visual analog method on a scale of 0 to 10. The volunteers were evaluated at baseline period, at one, two and three weeks after the beginning of the bleaching treatment, and again two weeks after the bleaching treatment only for the observations of the color, sensitivity and degree of satisfaction. The data were analyzed using the ANOVA test and the Tukey post test. The digital analysis showed the same level of color change in all times of analysis and wear time of thetrays; exception for the analysis time 7 days of the upper arch, which evidenced a greater color change for the longer time of wear time of the trays. The visual analysis evidenced that the greater wear time of the trays presented a greater color change, after the bleaching treatment. Dental sensitivity was observed throughout the bleaching treatment, but it was practically absent 14 days after treatment. Most of the volunteers did not follow the suggested prescriptions of the wear time daily of the trays,with those who used them for the shortest time presenting the highest degree of cooperation. The wear time of the trays/bleaching product for 8 hours/day, provided greater effectiveness of the color change in the visual and digital analysis, as well as greater degree of satisfaction of the volunteers. A discreet sensitivity was observed throughout the bleaching treatment, but it was practically absent 14 days after bleaching.It was observed that the volunteers did not follow correctly the prescriptions ofthe wear times of the trays/bleaching product, evidencing less the degree of collaboration of the volunteers for the greater wear times of the trays.
