title: Shear bond strength of a self-etching adhesive in primary and permanent dentition.
abstract: OBJECTIVE
  To assess the shear bond strength obtained with a new self-etching adhesive material (Adper Prompt-L-Pop) compared with the total-etch technique and posterior application of an adhesive (Prime & Bond NT) in both primary and permanent teeth.
  
  
  METHODS
  28 human teeth were selected (14 primary and 14 permanent). The vestibular and lingual surfaces were prepared in dentin, followed by application of the adhesive materials (Adper Prompt-L-Pop and Prime & Bond NT), in accordance with the instructions of the manufacturer. Compomer and composite (Compoglass and TPH Spectrum) were used as filler materials. The samples were thermocycled (150 cycles), after which adhesion was assessed with an Autograph AGS machine. The type of fracture produced was evaluated using an Olympus SCZ-CTV microscope. The data were compared by triple-factor analysis of variance, statistically significant differences being considered for P< 0.01.
  
  
  RESULTS
  The adhesion strength achieved with Prime & Bond NT involving both composite and compomer as restorative material was significantly greater than with Prompt-L-Pop. No differences were observed between the two dentitions.
