Lasers and air abrasion. New modalities for tooth preparation.

Hard tissue lasers and air abrasion units have a place in the modern dentist's armamentarium. Speed, comfort, ease of approach, public relations, and patient appeal are some of the advantages. The dentist's own comfort and satisfaction, knowing that he or she is doing the best dentistry without frightening the already fearful patient, should help the dentist decide which one of the modalities to incorporate into his or her practice.

[Five year survival of posterior adhesive bridges. Influence of bonding systems and tooth preparation].

The present study reports the final analysis of a randomized controlled clinical trial in which different designs of posterior resin-bonded bridges were evaluated for a period of at least 5 years. The operational hypothesis was that the bonding system and the preparation design used in posterior resin-bonded bridges have an influence on the survival and clinical functioning of these restorations. Survival in this study was defined at two levels: (1) 'primary' survival (survival without any debonding), and (2) 'functional' survival (survival including loss of retention on one occasion and successful rebonding of the original resin-bonded bridge without further debonding). Preparation of grooves in abutment teeth for posterior resin-bonded bridges appeared to be beneficial to their chance of survival. Resin-bonded bridges placed in the maxilla have a better prognosis than those made in the mandible. The bonding systems used in this study (etching/Clearfil F2, sand blasting/Panavia EX and silica-coating/Microfill Pontic C) appear to have no influence on the chance of failure with regards to the 'primary' survival. In rebonded posterior resin-bonded bridges, the bonding system silica coating/Microfill Pontic C was more retentive than the other systems tested.
