ABSTRACT
This study evaluated the effects of ultrasonic activation (US) associated to glycolic acid (GA) on smear layer, dentin structure and bond strength (BS) of filling/restorative material to root dentin. The roots were used for antimicrobial activity, dentin structure and BS evaluation, being distributed into seven groups, according to irrigation protocols: G1:DW+US; G2:17% EDTA; G3:QMix; G4:17% GA; G5:17% EDTA+US; G6:QMix+US; G7:17% GA+US. Scanning electronic microscopy, transmission electronic microscopy and push-out were performed, with specific statistical analysis for each evaluation. The highest smear layer removal occured in Groups 6 and 7 (p<0.05), and the largest collagen dispersion in Group 7, being similar to Group 2 and 5 (p>0.05). The highest BS of filling and restorative material occurred in Groups 6 and 7, and Groups 5, 6 and 7, respectively, being similars between them (p>0.05). The use of GA+US promoted effective smear layer removal and dentin structure preservation, improving the BS of filling/restorative material to root dentin.

A demanda por tratamentos restauradores estéticos tem aumentado consideravelmente nos consultórios odontológicos devido ao maior conhecimento por parte dos pacientes. Os laminados cerâmicos de dissilicato de lítio são excelentes opções de tratamento para realizar reabilitações estéticas devido às propriedades estéticas e de resistência do material. Este relato de caso tem como objetivo descrever as etapas envolvidas no protocolo clínico para realizar um tratamento restaurador com laminados cerâmicos ultrafinos.
The demand for aesthetic restorative treatments has increased considerably in dental offices due to increased knowledge on the part of patients. The lithium disilicate laminated ceramics are excellent options to restore dental aesthetics due to their aesthetic properties combined and resistance. This clinical report aims to describe the steps of the clinical protocol of a restorative treatment with ultra-thin ceramic laminates.
