A micro-computed tomography evaluation of long-oval canal preparation using reciprocating or rotary systems

Aim To evaluate, using micro‐computed tomography, the preparation of long‐oval root canals using a single reciprocating system versus a multiple‐file rotary system. Methodology Distal canals of thirty mandibular molars were selected and randomly assigned to one of two instrument groups (n = 15): Rec...

Description
Summary:Aim To evaluate, using micro‐computed tomography, the preparation of long‐oval root canals using a single reciprocating system versus a multiple‐file rotary system. Methodology Distal canals of thirty mandibular molars were selected and randomly assigned to one of two instrument groups (n = 15): Reciproc 40 (VDW, Munich, Germany) or BioRaCe system (FKG Dentaire, La Chaux‐de‐Fonds, Switzerland). The teeth were scanned before and after preparation of the canal by a SkyScan 1172 micro‐computed tomography scanner at 11‐μm resolution. Morphometric variations were measured by volume increases and by the remaining untreated canal surface area in the entire canal and as well as in each third of the canal. Data were compared using the Mann–Whitney test. Results The Reciproc system left significantly more areas untouched (P
