Artificial Intelligence in the Detection of Clinically Negotiable Second Mesio‐Buccal Canals in Periapical Images of Maxillary Molars

International Endodontic Journal, EarlyView.
ABSTRACT Aim Artificial intelligence (AI) has the potential to aid clinicians in assessing case difficulty in endodontics. The objectives of this study were to develop and validate deep learning models for the detection of clinically negotiable MB2 canals in periapical images of maxillary first and second molars, and to compare the performance of AI ...

Establishment of an MRI‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

International Endodontic Journal, EarlyView.
ABSTRACT Aim To establish a magnetic resonance imaging (MRI)‐based diagnostic approach for identifying ‘critical pulpal inflammation’ zones in a rat model of caries‐derived pulpitis. Methodology Caries‐derived pulpitis was induced in the molars of Sprague–Dawley rats using the caries‐derived pulpitis model.

Diagnostic Accuracy of Dentin Sclerosis by Optical Coherence Tomography and the North Carolina Index in Noncarious Cervical Lesions

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the diagnostic accuracy of optical coherence tomography (OCT) and the North Carolina Index (NCI) for identifying dentin type (sclerotic vs. nonsclerotic) in natural noncarious cervical lesions (NCCLs). Materials and Methods Thirty extracted human premolars with 30 NCCLs (90 regions of interest) were analyzed. Two blinded,

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...
