Evaluation of roughness promoted by different concentrations and exposure times to hydrofluoric acid on ceramic surfaces reinforced by lithium dissilicate

Introduction: Lithium disilicate-based ceramics have optical properties that make them stand out, and adhesion to the remaining dental structure is obtained from the sensitivity of this group of material to the action of hydrofluoric acid (AF), which allows the exposure of crystals of lithium...
