PURPOSE: To evaluate clinically the long-term(7 years)behavior of resin-based composite restorations and original fragment reattachments Methods: From an initial of 130 young subjects(8-18 years old), only60 fulfilled the inclusion criteria and consented to the evaluation of long-term follow up of their restorations. Out of a total of 90 injuried teeth ,70 were treated with direct composite restorations, and 20 with the original fragment reattachment tecnique. These 90 teeth were dividee according to traditional ( Andreasen, Ellis) classifications and according to a new classification (Spinas - Piroddi). Then the restoration were examined according to a modified version of USPHS method during the 7 -year follow-up.Results: Three year old composite restorations needed some kind of treatment( ranging from polishing to the reaplacement of the restoration); in the period between 3-5 years, all the restorations( belonging to all of the injuries types) needed a complete replacement. The results indicatesthat a restoration can probably be replaced three or four times before the tooth shows severe reduction of its adhesive properties. Composites cannot be used for long-term restorations; if the subject has completed his growth, the mandatory therapeutic alternatives are prosthetic restorations( Crowns, porcelain veneers ).
