In vitro analysis of shear bond strength and adhesive remnant index comparing light curing and self-curing composites

Murilo Gaby Neves, Gustavo Antônio Martins Brandão, Haroldo Amorim de Almeida, Ana Maria Martins Brandão, Dário Ribeiro de Azevedo Dental Press J Orthod. 2013 May-June;18(3):124-9.   Objective: To evaluate, in vitro, the shear bond strength of self-curing (ConciseTM – 3M and Alpha Plast – DFL) and light-curing composites (TransbondTM XT – 3M and Natural Ortho – DFL) used in orthodontics bonding, associated to Morelli metal brackets, with further analysis of adhesive remnant index (ARI) and enamel condition in scanning electron microscopy (SEM). Methods: Forty human premolars, just extracted and stored in physiologic solution 0.9% were used. Randomly, these samples [...]
