International Endodontic Journal, 2012 AbstractAimTo assess the impact of cross‐sectional root canal shape (CSRCS) on the canal volume that can be filled and the root filling material that remains following a subsequent retreatment procedure.MethodologyA total of 15 extracted two‐rooted human maxillary premolars and 15 mandibular first molars were used. Both root canals in the premolars (N =

Retreatability of a Bioceramic Root Canal Sealing Material
Journal of Endodontics, 2011The efficacy of retreatment techniques for BC Sealer (BCS) (Brasseler USA, Savannah, GA) removal has not yet been assessed. The purpose of this study was to evaluate the efficacy of solvent and rotary instrumentation in the removal of BCS when used in combination with gutta-percha (GP) as compared with AH Plus sealer (Dentsply, Tulsa, OK).The ...

Nonsurgical Root Canal Retreatment
2016Conventional endodontic therapy enjoys a high success rate; however, root canal treatment in cases of pulpal necrosis and cases with procedural errors will occasionally fail. Retreating such cases is often a challenge for clinicians. This chapter discusses both the diagnosis of retreatment needs and the steps to regain access to the previously treated ...

Endodontic retreatment: A rational approach to root canal reinstrumentation
Journal of Endodontics, 1992During nonsurgical endodontic retreatment, endodontic instruments are forced apically to remove the root canal filling material and regain canal patency. Undiscriminating burrowing down the canal in the apical direction may be fruitless and harmful. To avoid complications, the dentin overhanging the canal orifice must be removed and an unobstructed ...

A Current Overview of Root Canal Retreatment
2021Kök kanal tedavisinin temel amacı, kök kanal sistemini temizlemek, şekillendirmek ve dişin tekrar enfeksiyonunu önlemek için 3 boyutlu doldurma sağlamaktır. Primer kök kanal tedavisinin başarısız olduğu durumlarda dişin yeniden tedavi edilmesi gerekir. Bu yeniden tedavi, cerrahi yöntemlerden önce endodontik olarak gerçekleştirilebilir.

MTA Apexification Combined With Conventional Root Canal Retreatment
Australian Endodontic Journal, 2003ABSTRACTApexiflcation aims to induce apical closure of the open root apex with a hard‐tissue barrier, against which a root filling can be compacted. Despite the popularity of the apexification procedure, calcium hydroxide therapy has some disadvantages that include variability of treatment time, unpredictability of apical closure, difficulties with ...

Retreatment of Root Canals Filled with BioRoot RCS: An In Vitro Experimental Study
Journal of Endodontics, 2020The purpose of this study was to compare the speed of removal of root canal filling material and re-establishment of apical patency in root canals filled with a tricalcium silicate-based sealer (BioRoot RCS [BRCS]; Septodont, Saint-Maur-des-Fossés, France) versus a zinc oxide-eugenol sealer (Pulp Canal Sealer [PCS]; Sybron Endo Kerr, Orange, CA) and to

SummaryThe purpose of this study was to quantify the amount of remaining gutta‐percha/sealer on the canal walls when the Canal Finder system, hand instrumentation and a combination of both (hybrid technique) were used to remove these materials. The amount of apically‐extruded debris and the time required for removal were also recorded.
