Context: Due to advancements in adhesive technology and the introduction of fiber reinforcement, there has been a paradigm shift towards a more minimally invasive approach in coronal restoration of endodontically treated teeth.
Aims: This research aimed to evaluate and compare fracture resistance of postendodontic restoration using a self-adhesive bioactive resin and a bulk-fill composite with or without resin-impregnated glass fibers.
Materials And Methods: Mesio-occlusal-distal cavities were prepared on 80 extracted human maxillary premolars.
Background And Aim: The complete sealing of the pulpal space contributes to the better healing potential after an root canal treatment, and root canal sealers are an integral part of this treatment which comes in contact with the periodontal tissue. Biocompatibility of an endodontic sealer plays an important role in the root canal treatment procedure. Hence, the aim of the study was to compare and evaluate the cytotoxicity and genotoxicity effect of three resin-based sealers on human periodontal fibroblast cells.

Material And Methods: A chemomechanical preparation was done using the Protaper rotary instruments up to F3. The teeth were stored in an incubator at 37°C at 100% humidity and were categorized in three groups by random allocation, namely: Triple Antibiotic Paste (TAP), Calcium hydroxide paste (Apexcal) and Ledermix.
Aim: To evaluate and compare the antimicrobial efficacy of Ca(OH), 25% propolis, and 25% as intracanal medicaments in root canal treatment.
Materials And Methods: Total 60 freshly extracted permanent incisors were decoronated and chemomechanical preparation of root canal was performed. Samples were inoculated with a pure culture of and incubated for 21 days.
Aim: To evaluate the push-out bond strength of resin-based sealer to root dentin after a final flush of three different irrigants.
Materials And Methods: Thirty extracted human mandibular premolars were sectioned 4 mm below the cement-enamel junction and 60 horizontal disks of 2 mm from middle one-third of the root were prepared. The disks were immersed in 3% sodium hypochlorite for 1 minute, and after drying the disks, they were finally flushed with the following irrigants: group I-Chitosan solution, group II- juice (MCJ), and group III-ethylenediaminetetraacetic acid (EDTA).
Aim: This in vitro study intend to compare the cleaning effectiveness of Protaper universal sequence with reciprocating F2 Protaper and single rotary file One shape.
Materials And Method: 30 extracted human 1st mandibular molars were chosen for the analysis. Three NiTi file systems were used for mechanical preparation, ProTaper full sequence in rotary motion, single F2 Protaper file used in reciprocating motion, and One shape single file used in a circular motion.
Objectives: To evaluate and compare the anesthetic efficacy of anterior middle superior alveolar (AMSA) injection in single-visit endodontic therapy, an in vivo study.
Materials And Methods: Teeth in the maxillary anterior segment (N = 60) requiring single-visit endodontic (SVE) therapy were selected. A conventional syringe with 26-guage needle containing 1.
Background: Mineral trioxide aggregate (MTA) is a biomaterial that has been investigated for endodontic applications. With the increased use of MTA in pulp capping, pulpotomy, perforation repair, apexification and obturation, the material that would be placed over MTA as a final restoration is an important matter. As composite resins are one of the most widely used final restorative materials, this study was conducted to evaluate the shear bond strength of a composite resin to white mineral trioxide aggregate (WMTA) using three different bonding systems namely the two-step etch and rinse adhesive, the self-etching primer and the All-in-one system.

Materials And Methods: Thirty-one patients with completely formed single-rooted permanent teeth indicated for extraction were selected for the study. Crown was flattened for stable reference point and access cavity prepared.
The treatment of intrabony defects is a real challenge in molar teeth as it is chronic, slowly progressing disease which needs timely intervention. Periodontal inflammation associated with intrabony defect is not a separate entity as it secondarily affects the pulp causing retrograde pulpitis. However, treatment of these lesions will be complicated due to extensive bone loss.

It is essential for the clinician to have a clear picture and understanding of the pulpal anatomy and its variations. In a mandibular second premolar, it is rare to find extra roots and canals.

Materials And Methods: 90 single rooted permanent teeth were included in the study. After complete disinfection and access opening, the first microbiological pre-treatment sample (S1) was collected.
Aim: The effect of different concentrations of hydrogel of sodium ascorbate on bond strength of bleached enamel for varying periods of time and the mode of failure was evaluated.
Materials And Methods: Seventy enamel surfaces were obtained from 35 human extracted premolars. Specimens were divided into four groups: no bleaching (control), bleaching with carbamide peroxide gel, bleaching and application of 10% / 20% sodium ascorbate hydrogel for 30, 60, 120 min.
Dent Traumatol
October 2010
Intrusive luxation is one of the most severe types of dental traumatic injuries. The risk of occurrence of pulpal necrosis and inflammatory or replacement resorption is high. In an attempt to prevent or delay the appearance of such lesions, endodontic intervention is required soon after the occurrence of trauma.
