Materials And Methods: One hundred and thirty-six single-rooted premolars were decoronated and enlarged up to a file #45, autoclaved, inoculated with . , and incubated for 72 h.

Effects of conventional and herbal irrigants on microhardness and flexural strength of root canal dentin: An study.

Aim: The aim of this study was to compare the effects of herbal irrigants with conventional irrigants on microhardness and flexural strength of root dentin.

Materials And Methods: Sixty extracted permanent maxillary canines were selected. Decoronated roots were sectioned longitudinally into buccal and lingual segments to get 120 specimens.

Hemicrania continua secondary to neurogenic paravertebral tumor- a case report.

Objectives: Hemicrania continua (HC) is one of the trigeminal autonomic cephalalgias (TAC), where sympathetic dysfunction and autonomic dysfunction resulting in parasympathetic over activation with some evidence of sympathetic inhibition have been suggested as probable causes. However, cases of hemicrania continua secondary to sympathetic dysfunction due to neurogenic paravertebral tumor impinging on the sympathetic chain has not been previously reported. In this case, the probability of the sympathetic dysfunction was more likely based on the clinical features and management.

Assessment of computer-controlled local anesthetic delivery system for pain control during restorative procedures: A randomized controlled trial.

. Local anesthesia is given to decrease pain perception during dental treatments, but it may itself be a reason for pain and aggravate the dental fear. Computer-controlled local anesthetic delivery system (CCLADS) is one of the alternatives for decreasing the patients' pain during local anesthesia.

Comparing marginal microleakage of three Bulk Fill composites in Class II cavities using confocal microscope: An in vitro study.

Aim: This study aims to evaluate and compare microleakage at the occlusal wall and cervical wall in Class II cavities restored with one SonicFill Bulk Fill composite and two conventional Bulk Fill composites.

Materials And Methods: Thirty freshly extracted teeth were divided into three groups of 10 teeth each. Standardized Class II cavities were made on the mesial and distal surfaces of each tooth and restored using SonicFill Bulk Fill composite and two conventional Bulk Fill composites, Tetric Evo Ceram, and X-tra fil.

The comparison of the effects of different whitening toothpastes on the micro hardness of a nano hybrid composite resin.

Aim: The aim of this study was to compare the micro hardness of a nanohybrid composite resin after brushing with two herbal and one non-herbal whitening toothpastes.

Materials And Methods: We divided Eighty disk-shaped specimens of a nanohybrid composite (Tetric N Ceram, Ivoclar Vivadent, Asia) into 4 groups of 20 specimens each: Groups A, B, C, and D. Group A was control, Group B was brushed with Colgate total advanced whitening (Colgate-Palmolive (India) Limited), Group C with Salt and Lemon, Dabur (Dabur International Limited, Dubai, UAE), and Group D with HiOra Shine, Himalaya (The Himalaya Drug Company, India).

The Comparative Evaluation of Antibacterial Activity of Methacryloxydodecyl Pyridinium Bromide and Non-methacryloxydodecyl Pyridinium Bromide Dentin Bonding Systems Using Two Different Techniques: An In vitro Study.

Background: Adhesive systems have enabled clinicians to preserve more tooth structure by changing cavity designs. However, because of the polymerization shrinkage adhesive systems are not capable of totally prohibiting the gap formation between the cavity and restorative material of composite resin leading to colonization of oral microorganisms from saliva. One possible solution for this serious problem is to use dental materials with antibacterial properties.

In Vitro Evaluation of the Antimicrobial Efficacy of Four Endodontic Biomaterials against Enterococcus faecalis, Candida albicans, and Staphylococcus aureus.

Root canal sealers that possess good antimicrobial property can prevent residual and recurrent infection and contribute to successful endodontic therapy. This study evaluated the antimicrobial activity of four endodontic sealers, AH Plus, Tubliseal EWT, EndoRez, and iRoot SP, against three different microorganisms, E. faecalis, C.

Restoration of endodontically treated molars using all ceramic endocrowns.

Clinical success of endodontically treated posterior teeth is determined by the postendodontic restoration. Several options have been proposed to restore endodontically treated teeth. Endocrowns represent a conservative and esthetic restorative alternative to full coverage crowns.

Comparison of the efficacy of ethylene diamine tetraacetic acid and maleic acid in the removal of three calcium hydroxide intra-canal dressings: A spiral computerized tomography volumetric analysis.

Aim: To assess the efficacy of 17% ethylene diamine tetra acetic acid and 7% maleic acid in the removal of 3 calcium hydroxide preparations placed as intracanal medicaments.

Materials And Methods: The root canals of 60 single rooted premolars were prepared with a step back technique and randomly assigned into 3 experimental groups (n= 20). Group A was filled with plain calcium hydroxide mixed with distilled water in which barium sulfate was added for radio opacity, Group B was filled with Apexcal and Group C was filled with Metapex.

Grape seed extract as a potential remineralizing agent: a comparative in vitro study.

Objective: Remineralization is an effective treatment that may stop or reverse early tooth decay. Grape seed extract (GSE) is the potential remineralizing agent under investigation.

Materials And Methods: Sound human tooth sections were obtained from the cervical portion of the root and stored in demineralizing solution at 37°C for 96 hours to induce artificial root caries lesions.

Change of working length in curved molar root canals after preparation with different rotary nickel-titanium instruments.

Aim: The purpose of this study was to investigate change of working length in curved molar root canals after preparation with Profile, ProTaper and K3 Rotary Nickel-Titanium (Ni-Ti) instruments.

Materials And Methods: One hundred and eighty maxillary and mandibular molars were divided into group I having root curvature angle <300 and group II having root curvature angle >300 comprising 90 teeth in each group based on Schneider's method. Group II and I were further divided into sub group A, B and C having 30 teeth each based on type of instrument used.
