Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Evaluation of aesthetic integration between composite restorations and natural tooth in NCCL: a case report [PDF]

, 2015
NCCL (non carious cervical lesion) is defined as irreversible loss of dental hard tissue that does not involve bacteria. It consists of erosion, attrition, abrasion and abfraction that rarely occur alone.

Evaluation of the effect of different enamel surface treatments and waiting times on the staining prevention after bleaching [PDF]

, 2017
Bleached dental enamel can be more susceptible to staining than the enamel that has never been bleached, especially right after tooth bleaching. The aim of this study is to evaluate the effect of surface treatments and waiting time prior to contact with ...

Dental bleaching: patient perception and satisfaction

Minerva Dental and Oral Science
Teeth bleaching is a common practice performed by dental hygienists and dentists to correct aesthetic problems due to dental discoloration. Patients' opinions on this procedure may be different according to their personal experiences, expectations and individual sensitivities.

Dental Bleaching and New Possibilities: Literature Review [PDF]

Health Science Journal, 2018
Dental bleaching is an initial step in the analysis and reproduction of smile aesthetics, so it is very important that the dentist knows how to diagnose the causes of color change and to indicate whitening before proposing the appropriate dental procedure.

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

Developmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Effect of bleaching agents on enamel surface of bovine teeth: a SEM study [PDF]

, 2016
This study aimed to evaluate changes in the enamel surface of bovine teeth after whitening with exogenous bleaching agents: 10% carbamide peroxide (group 1), 16% carbamide peroxide (group 2) and 35% hydrogen peroxide activated by a light-emitting diode ...

Functional Imaging of the Outer Retinal Complex using High Fidelity Imaging Retinal Densitometry [PDF]

, 2020
We describe a new technique, high fidelity Imaging Retinal Densitometry (IRD), which probes the functional integrity of the outer retinal complex. We demonstrate the ability of the technique to map visual pigment optical density and synthesis rates in ...

Impact of a Modular Escape Game on Undergraduate and Continuing Dental Education

Journal of Dental Education, EarlyView.
ABSTRACT Purpose This study aimed to assess the educational impact and perceived relevance of a pedagogical escape game designed to reinforce key concepts related to dental biomaterials. Methods In 2023, a modular escape game comprising four mandatory stations and one bonus station was developed and integrated into two pedagogical settings: a ...
