Effect of Er:YAG, Co2 lasers, papain, and bromelain enzymes dentin treatment on shear bond strength of composite resin

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1575-1581, December 2022., 2022
Abstract Objective Effective bond strength of composite resin restoration leads to its durability, so evaluation of dentin surface treatment with enzymes and laser for higher bond strength is an important factor. Materials and Methods Sixty human molar teeth were cut at a depth of 2 mm of occlusal part and divided into six groups (n = 10).

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

open access: yesThe Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Effect of preparation design on marginal adaptation and fracture strength of ceramic occlusal veneers: A systematic review

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1391-1403, December 2022., 2022
Abstract Objectives This systematic review aims to investigate the effect of different preparation designs on the marginal fit and fracture strength of ceramic occlusal veneers. Materials and Methods Based on the PICO question and the search terms, an electronic search was performed in Google Scholar, PubMed (MEDLINE), Scopus, Cochrane Library, Web of ...

Segmentation of cortical bone, trabecular bone, and medullary pores from micro‐CT images using 2D and 3D deep learning models

open access: yesThe Anatomical Record, EarlyView.
Abstract Computed tomography (CT) enables rapid imaging of large‐scale studies of bone, but those datasets typically require manual segmentation, which is time‐consuming and prone to error. Convolutional neural networks (CNNs) offer an automated solution, achieving superior performance on image data.

Comparative evaluation of the postbleaching application of sodium ascorbate, alpha‐tocopherol, and quercetin on shear bond strength of composite resin to enamel

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1598-1604, December 2022., 2022
Abstract Objective This study aimed to evaluate and compare the impacts of the postbleaching application of sodium ascorbate, alpha‐tocopherol, and quercetin on the shear bond strength (SBS) of composite resin. Material and Methods 60 extracted intact maxillary first premolars were collected and were randomly divided into five experimental groups as ...

Statistical validation of a deep learning algorithm for dental anomaly detection in intraoral radiographs using paired data [PDF]

open access: yesarXiv
This article describes the clinical validation study setup, statistical analysis and results for a deep learning algorithm which detects dental anomalies in intraoral radiographic images, more specifically caries, apical lesions, root canal treatment defects, marginal defects at crown restorations, periodontal bone loss and calculus. The study compares
