ABSTRACT
OBJECTIVES:
This study investigated the ability of the fluorescence-aided identification technique (FIT) facilitated by a novel handpiece to simplify the removal of tooth-colored composite restorations with water-cooled rotating instruments. MATERIALS ANDMETHODS:
Five undergraduate students and five dentists (6-14 years of professional experience) were asked to remove dental restorations in vitro using both the conventional technique (CT) and the fluorescence-aided identification technique. The FIT method was performed on teeth restored in addition to the fluorescent composite resin with the non-fluorescent (FIT1) and fluorescent (FIT2) bonding agent. CEREC scans were superimposed and three-dimensionally analyzed with the software OraCheck 2.13 with respect to the cavity surface area still covered with composite resin and the volume of the needlessly removed sound hard tissue. Additionally, the removal procedure was timed.RESULTS:
The FIT2 group showed the most promisingresults:
the smallest cavity surface area covered by composite resin independent of the professional expertise, and for the dentist group, the smallest amount of removed sound hard tissue and the fastest removal.CONCLUSIONS:
Using the fiber optic of the handpiece for fluorescence excitation has been proven to be effective for performing the FIT, and therefore, to improve the removal of tooth-colored restorations. CLINICAL RELEVANCE This study is basic research to encourage the integration of fluorescence inducing light sources in dental treatment units by the manufacturers as a prerequisite for a simplified daily use of the FIT.Palavras-chave
