Evaluation of postoperative pain in endodontic retreatment with apical periodontitis using ozonated 2% chlorhexidine and 0.1% octenidine application: A randomized clinical trial.

Introduction: This study aimed to evaluate and compare postoperative pain (PP) in single-visit nonsurgical endodontic retreatment (SV NSER) with 2% chlorhexidine (CHX), 0.1% octenidine (OCT) with or without ozone, and 5.25% sodium hypochlorite (NaOCl).

Efficacy of microabrasion and resin infiltration techniques for masking of fluorotic white spot lesions: A randomized clinical study.

Aim: The aim of the study was to compare the esthetic treatment outcome and quantification of tooth color changes using microabrasion and resin infiltration techniques of fluorotic white spot lesions (WSLs).

Subjects And Methods: Sixty-six teeth with fluorotic small opaque white areas involving 25%-50% (very mild/mild fluorosis) of the surface were randomly assigned into two groups for microabrasion and resin infiltration techniques. To quantify tooth color changes, depicted by Delta E (DE), photographic analysis was performed using Adobe Photoshop CS5 Extended version by measuring Commission Internationale de l'Eclairage L*a*b* values of each tooth at two points, i.

Bonding strategies to deal with caries-affected dentin using cross-linking agents: Grape seed extract, green tea extract, and glutaraldehyde - An study.

Aim: This study evaluated the effect of three collagen cross-linking agents - proanthocyanidins (grape seed extract [GSE] and green tea extract [GTE]) and glutaraldehyde [GA] on microshear bond strength (μSBS) of caries-affected dentin (CAD)-resin complex.

Materials And Methods: Freshly extracted 96 teeth with caries up to the middle third of dentin were sectioned through the deepest part of the occlusal fissure, perpendicular to the long axis of the crown. Caries was excavated with large round bur until firm dentin was obtained, confirmed by visual inspection and tactile examination.

A case report on endodontic management of the rarest Vertucci's Type VIII configuration in maxillary second molar with three mesiobuccal canals.

Anatomic variations in mesiobuccal root (MBR) of maxillary molars are common. This variation is found to be more common in maxillary first molars as compared to second molars. However, finding three independent mesiobuccal (MB) canals in the MBR of maxillary molars is clinically a rare entity.

Effect of chemical cross-linkers on surface topography and microtensile bond strength of sound dentin: An study.

Aim And Objectives: The aim of the study was to investigate the effect of two different collagen cross-linking agents proanthocyanidin (Grape seed extract [GSE] and 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide) on the surface topography of etched dentin and microtensile bond strength (μTBS) of resin dentin bond.

Materials And Methods: Fifty-two sound human 3 molars were collected, and their occlusal surfaces were ground flat to expose dentin. Dentin surfaces were etched using phosphoric acid and then teeth were randomly divided into four groups, according to the dentin treatment: Group 1: wet bonding technique, Group 2: dry bonding technique, Group 3: 6.

Comparative evaluation of different direct pulp capping agents in carious tooth: An study.

Background: The success of direct pulp capping (DPC) depends on the preoperative assessment of pulpal status, intraoperative judgment after pulp exposure, and the biomaterials used to cap the pulp.

Aim: The study aims to compare the clinical and radiographic responses of the pulp-dentin complex after DPC with TheraCal LC, Biodentine, and current gold standard mineral trioxide aggregate (MTA) Plus.

Materials And Methods: Ninety vital permanent teeth with Class I deep carious lesions were randomly divided into three different groups.

Evaluation of Ozone Therapy in Endodontic Treatment of Teeth with Necrotic Pulp and Apical Periodontitis: A Randomized Clinical Trial.

Introduction: The aim of this study was to compare the effect of different application techniques of ozone on the prevalence of postendodontic pain in patients undergoing single-visit root canal treatment.

Methods: hundred eight patients with necrotic pulp in single-rooted teeth and apical periodontitis participated in the trial. A standard single-visit endodontics protocol was followed with 5.

Oxygen inhibition layer: A dilemma to be solved.

Objective: This study aimed to evaluate the thickness of oxygen inhibition layer (OIL), produced on various composite materials, and to compare their interlayer shear bond strength (SBS), by treating the OIL with various agents.

Materials And Methods: The thickness of OIL of three different composite materials (120 specimens divided into three groups) Group 1 - Ivoclar Tetric N-Ceram (nanohybrid composite), Group 2 - Ivoclar Te Econom Plus (microhybrid composite), and Group 3 - GC EverX Posterior (a short glass fiber-reinforced composite) was evaluated. Each group was divided into four subgroups (A, B, C, and D) depending on the surface treatment given - no surface treatment (control group), ethanol, water spray, and grinding with SiC paper.

Assessment of various genetic components through NCD-I and NCD-III designs of biparental mating in opium poppy.

Creation of genetic variability and development of varieties having higher yield potential depends on information about nature of gene action. The present investigation was undertaken to decipher the nature of gene action and allied genetic parameters involved in the inheritance of yield and yield-related component traits in opium poppy ( L.).

Stereomicroscopic evaluation of defects caused by torsional fatigue in used hand and rotary nickel-titanium instruments.

Objective: The aim of this study was to evaluate defects caused by torsional fatigue in used hand and rotary nickel-titanium (Ni-Ti) instruments by stereomicroscopic examination.

Materials And Methods: One hundred five greater taper Ni-Ti instruments were used including Protaper universal hand (Dentsply Maillefer, Ballaigues, Switzerland), Protaper universal rotary (Dentsply Maillefer, Ballaigues, Switzerland), and Revo-S rotary (MicroMega, Besançon, France) files. Files were used on lower anterior teeth.
