TEIXEIRA, Cibely de Medeiros; ROYA, Rafael Ribeiro de  and  OLIVEIRA, Marcelo Tomás de. Influence of variation on polymerization time in the shear bond strength for different cements to orthodontic brackets. Rev. Bras. Odontol. [online]. 2012, vol.69, n.2, pp. 220-223. ISSN 1984-3747.

This study evaluated the influence of curing time on shear bond strength of different cements activating them in times of 20 and 40s. We used 32 premolars recently extracted embedded in acrylic resin. After had flatted vestibular surface, orthodontics braces (Abzil Standard Edgewise Agile, Abzil3M) were cemented using to that Orthocem (FGM) and Transbond XT(3M) cements as recommended by manufacturers, just variation the polymerization time in 20 a nd 4 0 s econds. A nova o ne w ay s howed n o d ifferences between groups (p value = 0,317122). The tested cements showed similar results between them. No polymerization time influence could be observed.
