Effect of Root Canal Preparation on Propagation of Dentinal Microcracks. [PDF]

Iranian endodontic journal, 2021
This study evaluated the propagation of dentinal microcracks and the root canal volume increase after being prepared with two endodontic instruments: ProTaper Next (PTN) and WaveOne Gold (WOG) by micro-computed tomography analysis.We selected 48 maxillary molars randomly distributed in two groups: PTN and WOG.

Root dentinal microcracks: a post‐extraction experimental phenomenon? [PDF]

International Endodontic Journal, 2018
AbstractAimTo investigate the prevalence, location and pattern of pre‐existing microcracks in non‐endodontically treated teeth from fresh cadavers. Micro‐computed tomography (micro‐CT) technology was used as the analytical tool enabling full screening of the root dentine with the teeth retained in their original alveolar socket.MethodologyAs a pilot ...

Induction of dentinal microcracks during postspace preparation: A comparative microcomputed tomography study [PDF]

Journal of Conservative Dentistry, 2018
This study evaluated and compared techniques of postspace preparation for induction of dentinal microcracks utilizing microcomputed tomography (CT).A total of 45 extracted micro-CT scanned mandibular premolars were prepared and obturated. After the second micro-CT, samples were divided into three groups (n = 15).
