A deep learning approach to dental restoration classification from bitewing and periapical radiographs.

Objective: The aim of this study was to examine the success of deep learning-based convolutional neural networks (CNN) in the detection and differentiation of amalgam, composite resin, and metal-ceramic restorations from bitewing and periapical radiographs.

Method And Materials: Five hundred and fifty bitewing and periapical radiographs were used. Eighty percent of the images were used for training, and 20% were left for testing.

Efficacy of different endodontic irrigation protocols on shear bond strength to coronal dentin.

Aim: The purpose of this study was to evaluate the effect of etidronic acid on bond strength to coronal dentin.

Materials And Methods: A total of 75 human mandibular molars were sectioned 3 mm below the occlusal surface and then randomly divided into five groups according to irrigation solution used ( = 15): Group 1: 5 ml 2.5% sodium hypochlorite (NaOCl) +5 ml distilled water; Group 2: 5 ml 2.

The effect of five different universal adhesives on the clinical success of class I restorations: 24-month clinical follow-up.

Objectives: The aim of this study was to evaluate the 24-month clinical performance of universal adhesives on the restoration success of Class I carious lesions.

Materials And Methods: Five different universal adhesives (Gluma Bond Universal (GU), Clearfil Universal (CU), Prime&Bond Elect Universal (PU), All bond Universal (AU), and Single Bond Universal (SU)) were used in the self-etch and etch-and-rinse modes in 42 patients. The study was conducted with 10 groups, with 20 restorations in each group.

Micro-shear bond strength of universal adhesives used for amalgam repair with or without Alloy Primer.

Aim: The aim of this study was to investigate the adhesive performance of three different universal adhesives to repair aged amalgam by composite resins with or without Alloy Primer.

Materials And Methods: Sixty amalgam samples were prepared, aged, and randomly divided into 12 main groups according to adhesive procedures used. Composite buildups were placed on amalgam surfaces.

Bonding performance of universal adhesives on composite repairs, with or without silane application.

Aim: This study aims to investigate the adhesive performance of three different universal adhesives to repair aged composite restorations, with or without the application of silane.

Materials And Methods: A hundred and twenty resin composite samples were prepared, aged and randomly divided into 6 main Groups (single bond universal [SBU], All-Bond Universal [ABU], Futurabond U, Clearfil Tri-S Bond, Single Bond 2, and Clearfil SE Bond) and 2 subgroups (with or without silane). A microhybrid composite resin was placed on the aged composite surfaces and light cured.
