dc.description.abstractDifferent light sources have been used during dental bleaching procedures. More recently, a violet LED system was introduced as a promising and viable light source, which is capable to promote dental bleaching without chemical agents, although this light source could be also associated to a bleaching agent. This case report aimed to present the association of a violet LED and a bleaching agent over a discolored non-vital tooth. After anamnesis, clinical and radiographic examinations, a dental bleaching protocol was proposed as follow: 15 applications of the violet LED during 60 s (Bright Max Whitening, MMOptics) with 30 s interval between them. Before the last 5 applications, 35% hydrogen peroxide gel (Whiteness HP Maxx, FGM) was applied inside the pulp chamber and on enamel surface of the tooth (vestibular and palatal surfaces) and then the last 5 irradiations were performed. Three sessions were performed, with 7-days interval. Color assessment using a VITA classical scale and VITA EasyShade® spectrophotometer was carried out. After dental bleaching, color changed (tooth 21) from A3.5 to B2. The protocol used in this case report showed to be satisfactory for the non-vital tooth bleaching.en
