Can a Novel Device with Pure Dry Air Increase the Shear Bond Strength of Dental Composites to Dentin? An Experimental Study.

Modern conservative dentistry is taking the lead in daily clinical practice and is relying on adhesion. Whether it is a simple composite, ceramic inlays, onlays, veneers or crowns, the common factor for a successful outcome is a good bonding of these elements to dental structures. Thus, the purpose of this study was to evaluate the bond strength of resin composite to dentin when using a new device, the DENTIPURE KM™ (KM, Beirut, Lebanon), which provides a pure air flow, free of any contaminants and without humidity, when compared to other dental equipment.

The Effect of Dehydration on Tooth Color: A Prospective In Vivo Study.

Introduction The influence of dehydration on tooth shade constitutes a significant aspect, making it a pivotal area of study, particularly within the field of restorative dentistry. This prospective study was done to analyze, using a spectrophotometer, how dehydration affects the shade of the teeth. Materials and methods Twenty-five participants were recruited in this prospective study that took place in the Dental Care Center of Saint Joseph University of Beirut (Lebanon) between October 2022 and January 2023.

In vitro evaluation of the color stability and surface roughness of a new composite flow.

Background: The aim of this study was to evaluate the color stability and the surface roughness of a bulk-fill composite flow (SDR® Plus) by comparison to an ORMOCER-based composite (Ceram.x® Universal SphereTEC™) in order to confirm the validity of using SDR® Plus in the anterior region and to allow the prediction of its long-term results.

Material And Methods: 35 composite specimens of the same shade (A2), thickness (2mm) and shape of both types of composite were prepared.

Quantitative Measurements of the Depth of Enamel Demineralization before and after Bleach: An In Vitro Study.

Objective: This study is aimed at determining two main points. First, if the Canary System™ (CS), initially used to assess caries, can measure a decalcification depth of bleached enamel quantitatively, and second, whether or not whitening has a harmful effect on enamel. This device can be considered a useful tool in the clinical assessment of the progression of demineralization after bleaching.

A Two-Year Comparative Evaluation of Clinical Performance of a Nanohybrid Composite Resin to a Flowable Composite Resin.

Objective: This prospective in vivo study aimed to compare the clinical behavior of a flowable composite resin (Genial Universal Flo, GC) and a nanohybrid universal composite resin (Tetric Evo Ceram, Ivoclar Vivadent) used in Class I and II direct esthetic restorations in posterior teeth.

Methods: A total of 108 Class I and II direct restorations were performed in patients aged between 20 and 60 years. The originality of this study lies in the fact that both materials were placed in pairs, in the same clinical environment (i.

Clinical Comparative Evaluation of Nd:YAG Laser and a New Varnish Containing Casein Phosphopeptides-Amorphous Calcium Phosphate for the Treatment of Dentin Hypersensitivity: A Prospective Study.

Purpose: The aim of this study was to compare the effect of Nd:YAG laser to that of a new varnish: MI Varnish with RECALDENT (GC), for the treatment of dentin hypersensitivity, with a follow-up of 6 months. Dentinal hypersensitivity was evaluated using a new thermal test never before used on dental tissue.

Materials And Methods: A split-mouth design was used where teeth on one side received the same type of treatment.

[Amalgam, composites and compomers: a comparative histologic study of periodontal tissues (Part 2)].

Violation of the biologic width could induce different periodontal consequences depending on many factors such as the type of the restorative material used. In this study, the histological performance and the marginal adaptation of three filling materials (amalgam, composite resin and compomer) are evaluated after a period of three months. Class V cavities with apical margin located at the alveolar bone crest were prepared on Pointer dogs teeth and restored with these three materials.

[Amalgam, composites and compomers: comparative histologic study of effects on the periodontal tissues].

Amalgam, composite resin and compomer are frequently used in operative dentistry today. Earlier studies have shown the periodontal consequences induced by these materials if they have intracrevicular restorative margins. This study was performed on dogs where Class V cavities with apical margin located at the alveolar bone crest were prepared and restored with these materials.
