Fragment reattachment using a technique with no preparation and an adhesive system associated with an intermediate composite with good mechanical properties can restore part of the resistance of the fractured tooth
BACKGROUND / AIMS Fragment reattachment is a procedure that offers advantages , such as preservation of tooth structure and maintenance of color , shape , and translucency of the original tooth .
The aim of this study was to analyze the reattachment techniques used to restore anterior teeth fractured by trauma .
Shear bond strengths of tooth fragments reattached or restored.
This study investigated the shear bond strengths of sectioned human m and ibular incisor edge fragments reattached using  luting cements , bonding agents or restored with composite resins . Seventy teeth were r and omly distributed among six experimental groups and a control group . Leaving half of the anatomic crowns exposed , the teeth were embedded in self-cure acrylic resins with the exposed part then sectioned . The fragments in groups 1 - 4 were bonded to their respective teeth using Clearfil Liner Bond 2V , Scotch Bond Multi Purpose Plus , Panavia-F and 3 M Opal Luting cement . The 5th and 6th groups were restored with composite resins ( Silux 3 M and Clearfil AP-X ) using their bonding agents ( Single Bond and Clearfil SE Bond ) . The results indicated that reattachment of fractured incisal fragments by using new generation bonding agents was effective against shear stresses , comparable with the intact teeth . Instead of restoration with composite resins therefore reattachment of a fractured fragment might be more preferable in cases of dental trauma
