Assessment of Biomechanical Preparation Influence on Various Root Canal Curvatures.

Aim: To determine the influence of biomechanical preparation on various parameters of root canal curvature.

Materials And Methods: A total of 72 tooth roots with moderate (10-25°) and severe canal curvature (26-75°) were selected and embedded in autopolymerizing acrylic resin for which cone-beam computed tomography (CBCT) image analysis was performed. Schneider angle, canal access angle (CAA), and the radius of curvature were determined preoperatively using auto-computer-aided design (CAD) 2021 software.

Evaluation of Root Dentin Damage during Retreatment Procedure using Various Engine-Driven Retreatment File Systems-A Micro-CT Study.

Aim: The aim of this research was to assess the damage to root dentin that arises from retreatment with different engine-driven NiTi retreatment files employing micro-computed tomography.

Materials And Methods: Sixty mandibular premolar teeth having a single root and root canal that were recently extracted were gathered and stored. The specimens were de-coronated at the cementoenamel junction under water irrigation to achieve a homogeneous root length of 16 millimeters.

Cephalometric Assessment of Dentoskeletal Characteristics in Children with Digit-sucking Habit.

Background: Nonnutritive sucking can turn into a continuous behavior practiced unconsciously, leading to a deleterious oral habit. Digit-sucking habits are an important etiological factor for malocclusion.

Aim: To investigate the effect of the digit-sucking habit on dentofacial structures by employing a cephalometric analysis.

Indigenous irrigants as potent antimicrobials in endodontic treatment: An study.

Background: The success of an endodontic treatment depends on effective disinfection and complete sealing of root canal. The irrigants that are currently used in the field of endodontics have certain limitations, so the quest for an ideal root canal irrigant continues. Nowadays, the use of herbal extracts such as Triphala and liquorice are used for their potent antimicrobial activity and less side effects.

Effect of three commercially available chewing gums on salivary flow rate and pH in caries-active and caries-free children: An study.

Background And Aim: Adequate salivary flow is an important requisite in the maintenance of oral health. Salivary flow increases in response to both gustatory (taste) and mechanical (chewing) stimuli. Hence, the aim of the present study was to know the efficacy of commercially available chewing gums (sugar free and sugared) on salivary flow rate (SFR) and pH in caries-active and caries-free children.

Comparative Analyses of Smear Layer Removal Using Four Different Irrigant Solutions in the Primary Root Canals - A Scanning Electron Microscopic Study.

Introduction: A clinician's path to success is a clean root canal system with three dimensional seal. Mechanical instrumentation of root canals alone leaves behind a smear layer covering the dentinal walls. Instrumentation must always be supported by use of irrigants which are considered as an essential prerequisite for root canal debridement.

Comparative Evaluation of Fluoride Releasing Ability of Various Restorative Materials after the Application of Surface Coating Agents - An In-vitro Study.

Introduction: Fluoride plays a key role in prevention of dental caries and is also an essential element for oral health promotion both in children and adults.

Aim: The aim of the present study was to evaluate the effect of surface coating (petroleum jelly, G-Coat Plus) on the fluoride releasing property of conventional Glass Ionomer Cement (GIC) and Zirconomer.

Materials And Methods: A total of 30 disk shaped brass mold specimens (6±0.

Color stability of esthetic restorative materials used in pediatric dentistry: An in vitro study.

Background: Children consume foods that are colorful which contain food additives that stain not only the tooth structure but also the restorations. As esthetics is of prime concern for both parents and children nowadays, long-term color stability of restorative materials is of utmost importance.

Aim: To evaluate the color stability of two tooth-colored restorative materials (conventional glass ionomer cement [GIC] and giomer) when immersed in various consumable drinks and food (aerated beverage, ice candy, and health drink) at different immersion periods (low, moderate, and high).

The Comparison of Shear Bond Strength Between Fibre Reinforced Composite Posts with Three Different Composite Core Materials - An In vitro Study.

Aim: The aim of this study is to compare the shear bond strength between fiber reinforced composite post with three different composite core materials.

Materials And Methods: The materials used for the study were: 30 maxillary central incisors, pre fabricated fiber reinforced composite post (postec plus posts), Multi-core heavy body, Ti-core, Fluoro-core, Etchant gel, Silane coupling agent, Dentin bonding agent, Standardized gutta percha points, Rely-X dual cure composite resin. A total of 30 human maxillary central incisor were selected for this study.

Dental pulp response to collagen and pulpotec cement as pulpotomy agents in primary dentition: A histological study.

Introduction: As the search for a better biocompatible medicament is on, aim of the present study was to evaluate the pulpal response to collagen particles impregnated in antibiotics (Biofil-AB™) and new commercially available cement (Pulpotec) that can be used as pulpal medicament.

Materials And Methods: Total sample of 40 teeth from 20 children in the age group of 7-10 years which are noncarious having bilateral retained primary teeth were enrolled for the study. Nine teeth each were treated with collagen particles (group I) and Pulpotec cement (group II), and the remaining samples were discarded due to various reasons.
