An experimental method to measure gear tooth stiffness throughout and beyond the path of contact [PDF]

, 2001
A method is presented that allows the accurate measurement of the tooth pair stiffness of a pair of spur gears. The method reveals the stiffness behaviour throughout the full length of the normal path of contact and also into the extended contact region ...

The application of MTA as apical plug for root canal obturation: In vitro study [PDF]

Stomatološki glasnik Srbije, 2018
Introduction Prognosis of endodontically treated tooth is directly correlated to the quality of apical obturation. Modern concept of endodontics in particular way points out the quality of apical filling.

Tooth Sensitivity, Bleaching Efficacy, and Quality of Life in Young People and Adults: A Stratified, Randomized Bi‐Center Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study compared tooth sensitivity, bleaching efficacy, and the impact on oral health‐related quality of life between at‐home and in‐office tooth bleaching in adults and young individuals. Materials and Methods Eighty participants, 40 young people (14–20 years) and 40 adults (40–60 years), were randomly assigned to receive either

The evolutionary paradox of tooth wear: simply destruction or inevitable adaptation? [PDF]

, 2013
Over the last century, humans from industrialized societies have witnessed a radical increase in some dental diseases. A severe problem concerns the loss of dental materials (enamel and dentine) at the buccal cervical region of the tooth.

Air‐Abrasion With Aluminum Oxide Particles in Non‐Carious Cervical Lesions: Impact on Sclerotic Superficial Layer, Surface Topography, and Restorative Adhesive Performance

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of airborne‐particle abrasion (APA) with aluminum oxide on superficial dentin sclerosis, surface topography, and bonding performance of a universal adhesive in natural non‐carious cervical lesions (NCCLs), using dentin classification by the North Carolina Index (NCI) and Optical Coherence Tomography Index (OCT).

Evaluation of inflammatory vascular responses in patients with severe periodontitis by contrast-enhanced perfusion dental MRI

European Radiology Experimental
Background Periodontitis is characterized by the inflammatory destruction of tooth-supporting alveolar bone. Dental magnetic resonance imaging (MRI) using dynamic contrast-enhanced perfusion can potentially detect vascular inflammatory responses.

In vitro evaluation of dentin tubule occlusion by three bioactive materials: A scanning electron microscopic study

Dental Research Journal, 2019
Background: Dentin hypersensitivity (DH) is a common problem characterized by a short, sharp pain. Reduction of dentin permeability by occluding dentin tubules is considered as a method for treating DH.

Effect of Silane Incorporation on the Bonding Performance of Universal Adhesives to Dentin

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Purpose The effect of silane in universal adhesives (UAs) on dentin adhesion remains unclear. Therefore, this study evaluated the dentin bonding of UAs with and without silane immediately and after thermocycling. Materials and Methods Sixty‐four sound human molars were randomly assigned to eight groups according to silane incorporation (UAs ...

Implications of European Union Sodium Perborate Restrictions for Intracoronal Bleaching Procedures: A Narrative Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To critically evaluate current and emerging intracoronal bleaching agents and to provide an evidence‐informed framework for clinical decision‐making in the postsodium perborate era. Overview The declining availability of sodium perborate, particularly within the European Union, has substantially altered contemporary intracoronal ...
