- Abstract
<bold>Background/aim: </bold>Accurate removal of composite bonded titanium trauma splints (TTS) can be challenging. The aim of this study was to evaluate a Fluorescence-aided Identification Technique (FIT) compared with a conventional light source (CT) for removal of trauma splints regarding loss of tooth substance, residual composite, and time taken.<bold>Materials and Methods: </bold>Twenty maxillary models with six bovine teeth (13 - 23) were fabricated. An optical three-dimensional impression was taken and a TTS was applied from 12 to 22 with two bonding sites on every tooth under standardized conditions using an etch-and-rinse adhesive and resin composite. Two operators removed 10 splints each (5x FIT and 5x CT). For FIT, a 405 nm light-emitting headlamp was used. Time was recorded. A post-operative scan was superimposed on the pre-operative scan using OraCheck software. A qualitative and quantitative analysis of tooth defects and composite remnants was performed by two operators and statistically analyzed.<bold>Results: </bold>Compared with the CT, FIT led to significantly fewer and smaller enamel defects (mean volume: -0.04 mm3 vs -0.33 mm3 ) (P < 0.001), significantly less composite remained (mean volume: 0.02 mm3 vs 0.28 mm3 ) (P < 0.001), and the removal procedure with FIT was significantly quicker (mean: 162 seconds vs 268 seconds) (P < 0.001), CONCLUSIONS: FIT facilitated the removal of composite used to bond trauma splints leading to less time-consuming as well as less invasive treatment. It left fewer composite residues on enamel surfaces.
