Effect of Cold Plasma on the Penetration Depth of AH26 and Beta Resin Sealers in Dentinal Tubules.

Statement Of The Problem: The creation of a proper seal of the root canal with canal-filling materials, such as gutta-percha and sealer, is one of the essential factors in the success of root canal treatment. In addition, the penetration depth of the sealer is one of the influential factors in creating a proper seal, which improves the sealing ability of the canal and the burial of microorganisms.

Purpose: This study aimed to investigate the effect of cold atmospheric plasma on the depth of tubular penetration of two types of resin sealer: AH26 and Beta RCS sealers.

Comparison of coronal sealing of flowable composite, resin-modified glass ionomer, and mineral trioxide aggregate in endodontically treated teeth: An study.

Background: Coronal seal is one of the essential factors that affects the success of endodontic treatment and reinforces the apical seal. The intra-orifice barrier is an efficient alternative approach to decrease coronal leakage in endodontically treated teeth and various materials have been used for this purpose. This study aimed to compare the coronal sealing of flowable composite, resin-modified glass ionomer (RMGI), and mineral trioxide aggregate (MTA) in endodontically treated teeth.

Root and Canal Morphology of Maxillary Teeth in an Iranian Subpopulation Residing in Western Iran Using Cone-Beam Computed Tomography.

Introduction: Accurate information regarding the morphology of roots and canals is a prerequisite for successful endodontic treatment. This study aimed to assess the number of roots and canals and canal type of maxillary teeth according to the Vertucci's classification in an Iranian subpopulation residing in Western Iran using cone-beam computed tomography (CBCT).

Methods And Materials: In this cross-sectional study, a total of 1750 teeth were evaluated on CBCT scans taken for purposes other than this study.

evaluation of coronal discoloration following the application of calcium-enriched mixture cement, Biodentine, and mineral trioxide aggregate in endodontically treated teeth.

Background: This study sought to assess and compare coronal discoloration following the application of white mineral trioxide aggregate, Biodentine, and calcium-enriched mixture cement in endodontically treated teeth.

Materials And Methods: In this experimental study, 64 freshly extracted sound human premolars were selected, cleaned, and stored in saline. After cleaning, shaping, and obturation the root canal of the teeth, the teeth were randomly assigned to one control ( = 4) and three experimental ( = 20) groups.

The Study of Prescribing Errors Among General Dentists.

Introduction: In dentistry, medicine often prescribed to relieve pain and remove infections .Therefore, wrong prescription can lead to a range of problems including lack of pain, antimicrobial treatment failure and the development of resistance to antibiotics.

Materials & Methods: In this cross-sectional study, the aim was to evaluate the common errors in written prescriptions by general dentists in Kermanshah in 2014.

Treatment of a vertical root fracture using dual-curing resin cement: a case report.

Introduction. Vertical root fracture (VRF) is one of the most frustrating complications of root canal treatment. The prognosis of the root with VRF is poor therefore tooth extraction and root amputation are usually the only treatment options.

Effect of Ascorbic Acid on Shear Bond Strength of Orthodontic Brackets Bonded with Resin-modified Glass-ionomer Cement to Bleached Teeth.

Background And Aims: Bleaching can considerably reduce shear bond strength (SBS) of orthodontic brackets bonded with composite adhesives. Application of antioxidants is a method to reverse the negative effect of bleaching on composite-to-enamel bond. However, the efficacy of antioxidants in increasing the SBS of brackets bonded using resin-modified glass-ionomer cement (RMGIC) has not been studied, which was the aim of this study.
