Effect of different obturating techniques and sealers on the removal of filling materials during endodontic retreatment.

Background: Adequate removal of previous root filling materials is an important objective during endodontic retreatment.

Aim: This study was aimed to evaluate the influence of obturation quality and sealer type on the removal of root filling materials during endodontic retreatment using micro-computed tomography (μ-CT).

Materials And Methods: Ninety extracted mandibular premolars were randomly assigned to two groups ( = 45) based on the type of sealer (AH Plus and BioRoot RCS) and three sub-groups based on the obturating technique used, i.

Interfacial adaptation and penetration depth of bioceramic endodontic sealers.

Background: Sealers play an important role in the success of root canal treatment. The efficacy of root canal sealer is enhanced by its tubular penetration and adaptation properties.

Aim: The aim of this study is to evaluate the interfacial adaptation and penetration depth of Bioroot RCS and MTA Plus sealers to root dentin.

Microhardness and Penetration of Artificial White Spot Lesions Treated with Resin or Colloidal Silica Infiltration.

Introduction: Infiltration of early enamel lesions by materials having remineralizing capacity seems to improve aesthetics and arrests caries progression.

Aim: To evaluate and compare the surface microhardness and penetration depth of a low viscosity resin and colloidal silica nanoparticle infiltrates into artificially created white spot lesions.

Materials And Methods: Forty extracted human central incisors were embedded in acrylic resin blocks exposing the labial surfaces of the crowns.

Autotransplantation of mandibular third molar: a case report.

Autogenous transplantation is a feasible, fast, and economical option for the treatment of nonsalvageable teeth when a suitable donor tooth is available. This paper presents successful autotransplantation of a mature mandibular left third molar (38) without anatomical variances is used to replace a mandibular left second molar (37). The mandibular second molar was nonrestorable due to extensive root caries and resorption of distal root.
