Comparative evaluation of marginal adaptation of mineral trioxide aggregate, Biodentine, and geristore as a root end filling material: An scanning electron microscope study.

Aim: The aim of this study was to measure the quality of marginal adaptation of three root end filling materials by scanning electron microscope (SEM).

Methodology: Thirty extracted human permanent single-rooted single canal maxillary anterior teeth with mature apices were prepared up to 60 K-file and obturated. Teeth were resected 3 mm from the apex using a cross-cut fissure bur at 90° angle to the long axis of the tooth.

Evaluation of remaining dentin thickness following use of three different rotary nickel-titanium retreatment files: A cone-beam computed tomography study.

Aim: The aim of the study is to measure the amount of remaining dentin thickness (RDT) following retreatment using three different rotary nickel-titanium (NiTi) systems.

Methodology: Mesiobuccal roots of 45 extracted maxillary first molars were prepared up to F ProTaper File and obturated. After cone-beam computed tomography (CBCT) imaging, to evaluate the obturation, the samples were randomly assigned to three retreatment groups ( = 15).

Grape seed extract: An innovation in remineralization.

Aim: The aim of this study was to determine remineralizing potential of grape seed extract (GSE) compared to casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and calcium glycerophosphate (CaGP) through pH-cycling model and subsequent evaluation using polarized light microscope (PLM).

Subjects And Methods: Twenty sound human teeth fragments of ten teeth were obtained from the cervical portion of the roots and were stored in demineralizing solution for 96 h at 37°C to induce artificial root carious lesion. The sections then were divided into four treatment groups including: 6.

Bilateral Three Rooted Mandibular Premolars and Four Rooted Mandibular First and Second Molar: A Rare Anatomical Variant.

The mandibular premolars and molars exhibit wide variations in the form of roots and root canals. A bilateral symmetry of three rooted mandibular first and second premolar and four rooted mandibular first and second molar in a same patient is a rare entity and one such case is presented in this case report.
