Technique Acquisition in the Use of Two Thermoplasticized Root Filling Methods by Inexperienced Dental Students: A Microcomputed Tomography Analysis

Micro‐CT evaluation of root filling quality in oval‐shaped canals

“…, Mirfendereski et al . ). In both groups, the greatest amount of sealer was observed in the apical third.…”

“…On the other hand, in the WVC group, the thicker sealer layer in this area appeared to reflect a suboptimal heat softening of gutta‐percha (Mirfendereski et al . ). It has been speculated that variations in the quality of the filling procedure could be inherent to all techniques independent of the degree of clinical experience (Mirfendereski et al .…”

“…Conventional root fillings consist of a core material, usually gutta‐percha, that should be closely adapted to the canal wall, and cement that seals the interface between the core and the dentine (Schilder , Leduc & Fishelberg , Mirfendereski et al . ).…”

“…These might lead to inaccuracies because some filling material might be lost during sample preparation (Mirfendereski et al . ). Thus, an ideal experimental model should allow the preservation of sample integrity to avoid irreversible structural damage (Somma et al .…”

A High-resolution Computed Tomographic Study of Changes in Root Canal Isthmus Area by Instrumentation and Root Filling

“…In endodontic research, m-CT technology is frequently used for the study of root canal anatomy and for the assessment of changes in root canal morphology by instrumentation (7,(15)(16)(17)(18)(19)(20)(21). The quality of root canal obturation has also been investigated by m-CT (22)(23)(24)(25)(26), and a few studies have focused on filling of the isthmus area by obturation. Recently, Paqu e et al (8) showed that dentin debris is formed and packed into the isthmus area during rotary instrumentation.…”
