Micro‐computed tomography of tooth tissue volume changes following endodontic procedures and post space preparation

Abstract

Access cavity and post space preparation are the procedures during root canal treatment which result in the largest loss of hard tooth tissue structure. Cast post space preparation causes a larger loss of tooth structure than fibre post space preparation. This should be taken into account when planning root canal treatment and restoration of root filled teeth that are to be restored with cuspal coverage restorations.

Efficacy of D‐RaCe and ProTaper Universal Retreatment NiTi instruments and hand files in removing gutta‐percha from curved root canals – a micro‐computed tomography study

“…In the present study, micro-CT imaging displayed remnants of gutta-percha and sealer after retreatment, which was expressed as percentage of the preoperative volume of the filling material, similar to previous studies (Barletta et al 2007, Hammad et al 2008. The values of pre-and postoperative dentine volumes were assessed, and loss of hard tooth tissue during removal was expressed as mm 3 (Ikram et al 2009 Hassanloo et al 2007, Gu et al 2008, Betti et al 2009, Marfisi et al 2010, Kfir et al 2012, to simplify standardization of specimens. Therefore, investigations on nonsurgical retreatment in curved root canals are rare (Valois et al 2001, Ferreira et al 2001, Schirrmeister et al 2006b, Gergi & Sabbagh 2007, Ç elik Ü nal et al 2009, Aydin et al 2009), although these teeth rather represent the clinical situation in which many of the treated teeth have a complex anatomy (Duncan & Chong 2010).…”

Influence of oval and circular post placement using different resin cements on push‐out bond strength and void volume analysed by micro‐CT

“…High‐resolution micro‐computed tomography (micro‐CT) can measure the volume of three‐dimensional shapes such as canals, gaps and voids within cements (Ikram et al . , Keleş et al . ).…”

Access cavity preparation training using haptic virtual reality and microcomputed tomography tooth models

“…Using micro-CT, it is also possible to form threedimensional images of teeth and bone from which structural parameters can be derived. Reports have shown the effectiveness of quantitative evaluation of endodontic access cavity preparation (Ikram et al 2009), root canal preparation (Peters et al 2003) and canal filling (Hammad et al 2009) using micro-CT.…”
