Aim: The aim of the study is to compare the push-out bond strength of bioceramic and epoxy sealers after using various final irrigants.

Materials And Methods: Hundred single-rooted teeth were divided into two groups ( = 50) according to the sealer used: Group A: Bio C (bioceramic sealer), Group B: Dia-Proseal (epoxy sealer). Each group was subdivided into five subgroups ( = 10) according to the final irrigation protocol: Group A1 and B1 - 5% glycolic acid (GA), Group A2 and B2 - 17% GA, Group A3 and B3 - 0.

Despite advances in the 21 century, dental caries still remains to be one of the most common infectious diseases. Its prevalence was confirmed by the World Health Organization and affirms dental caries as a major health problem in all over the world. Even though the process of tooth decay is multifactorial, the oral bacteria, mutans streptococci, such as and Streptococcus sobrinus, are considered to be causative agents of dental caries in human.

Coronavirus disease 2019 (COVID-19) has been a major health concern globally ever since it was declared as Pandemic by the World Health Organization in March 2020. Due to the evolving and contagious nature of coronavirus, it continues to remain a threat for dental health-care personnel. As the virus travels from person-to-person via direct contact through droplet inhalation, cough, and sneeze or through contact transmission, it remains infectious even through inanimate surfaces.

Aim: The present study aimed to evaluate and compare the sealing ability of mineral trioxide aggregate (MTA)-Angelus, Biodentine™, and EndoSequence cement in furcation perforations using protein leakage assessment.

Materials And Methods: The present study was conducted using seventy extracted human maxillary and mandibular molars with intact furcation. The samples were randomly allocated into three groups ( = 20) based on repair material used: Group 1 - MTA-Angelus, Group 2 - Biodentine™, and Group 3 - EndoSequence.

External root resorption of permanent teeth is a multifactorial process. This article presents an unusual case of localized idiopathic extensive external root resorption involving the whole mesial root of the right mandibular first molar in a 42-year-old female patient. No significant systemic, dental, or familial findings could be identified as a possible cause.

Polymerization shrinkage is one of the dental clinician's main entanglements when placing resin-based composite restorations. None of the method can assure a perfectly sealed restoration for adhesive restorative materials; clinicians must abode problems of polymerization shrinkage and its possible ill effects. The objective of this article is to review different incremental techniques that can ruin the polymerization shrinkage stress of direct composite restoration.

Periapical lesions are the most common pathological conditions involving teeth which often require surgical intervention. To achieve optimal healing both clinically and radiographically, bone grafts and barrier membranes have been used to fill the periapical defect after degranulation of the lesion. Colostrum is one of the new materials, which has osteoinductive or regenerative potential.

Article Synopsis
  • Perforation creates an artificial connection between a tooth's root canal and surrounding tissues, complicating treatment and potentially worsening outcomes if not handled correctly.
  • Various materials have been suggested in the literature for sealing these perforations, with many comparative studies assessing their effectiveness.
  • This article aims to provide a comprehensive overview of the materials used for perforation repair throughout history and reviews literature from the past 40 years on the treatment of perforations with different root repair materials.

Introduction: The purpose of this study was to compare the incidence of dentinal micro cracks after instrumentation with various types of NiTi files in rotary and reciprocating motion.

Materials And Methods: One hundred human extracted mandibular central incisors were taken and divided into 10 groups (n=10 teeth per group). Group 1- No preparation, Group 2 - Hand instrumentation, Groups 3,4 - ProTaper files in rotary and reciprocating motion, Groups 5,6 - ProTaper Next files in rotary and reciprocating motion, Groups 7,8 - Oneshape files in rotary and reciprocating motion, Groups 9,10 - Reciproc files in rotary and reciprocating motion.

Introduction: Successful endodontic treatment depends on achievement of a fluid-tight seal that is not possible solely with gutta-percha and requires the use of a root canal sealer. Eugenol, which is a principal component in zinc oxide-eugenol (ZOE) based sealers, is reported to produce a volumetric expansion of gutta-percha. The aim of this study was to evaluate the three-dimensional expansion of gutta-percha at various powder/liquid ratios of ZOE-based sealer by using spiral computed tomography (SCT).

Maxillary first molar can have a mesio-buccal-2 (MB2) orifice located palatally, but adjacent to the mesio buccal orifice. An awareness and understanding of this root canal morphology can contribute to the successful outcome of root canal treatment. This report discusses endodontic treatment of a maxillary first molar with unusual location of second mesio buccal orifice.
