Item Influência do tipo de escova e da força de escovação no desgaste dental erosivo(Centro Universitário do Estado do Pará, 2019) Souza, Cíntia de Melo Silva; Esteves, Renata Antunes; Carneiro, Paula Mendes Acatauassú; http://lattes.cnpq.br/7375951134055063; http://lattes.cnpq.br/0001642348652061; Loretto, Sandro Cordeiro; http://lattes.cnpq.br/6988325260181483; Alves, Eliane Bemerguy; http://lattes.cnpq.br/3442162475756349The objective of this study was to evaluate, in vitro, the influence of manual toothbrushes with different characteristics and two brushing load on microhardness and surface loss of bovine enamel after erosive and abrasive cycling. Specimens of bovine enamel (n = 10) were made in 3x3mm dimensions, where initial erosive lesions were made by citric acid cycling and randomly distributed in 10 experimental groups: A1- Colgate Slim Soft with 1.5N load; A2- Colgate Slim Soft with 3N load; B1- Curaprox 5460 with 1.5 N load; B2- Curaprox 5460 with 3N of load; C1- Oral B Indicator with 1.5N load; C2- Oral B Indicator with 3N load; D1- Johnson & Johnson Professional with 1.5N load; D2- Johnson & Johnson Professional with 3N load; E1- Sensodyne Repair & Protect with 1.5N load; E2- Sensodyne Repair & Protect with 3N load. Microhardness evaluation was performed after abrasive challenge. Surface loss was assessed by non-contact optical profilometry after 5 days erosive and abrasive cycling. Results were evaluated by analysis of variance (ANOVA) and Tukey test, with a significance level of 5%. It was concluded that the microhardness was influenced by the load, where the higher load showed increased hardness when removing the softened enamel layer.? Surface loss was influenced by brush characteristics and load, and soft brushes promoted less surface loss.
