Shear bond strength of repair composite resin to an acid-etched and a laser-irradiated feldspathic ceramic surface.

Objective: The purpose of this study was to evaluate the shear bond strength of a repair composite resin to a feldspathic ceramic surface that had been either etched with 9.5% hydrofluoric acid (HFA), irradiated by an Er:YAG or Nd:YAG laser, or etched with 9.5% HFA after being irradiated by each laser type.

Pre-eruptive coronal resorption and congenitally missing teeth in a patient with amelogenesis imperfecta: a case report.

This clinical report describes a male with autosomal recessive generalized hypoplastic amelogenesis imperfecta. This case is unusual in coronal resorptions prior to tooth eruption. This finding has been reported in some cases of autosomal recessive, autosomal dominant and X linked amelogenesis imperfecta (AI).
