Dysregulation of Oral Microbial Eicosapentaenoic Acid Induced by Chronic Restraint Stress Exacerbates Periodontitis via M1 Macrophage Polarization

Advanced Science, EarlyView.
ABSTRACT The intricate interplay between chronic psychological stress and periodontitis, mediated by oral microbiota and macrophage polarization, remains largely enigmatic. Here, we demonstrate that chronic restraint stress (CRS) exacerbates periodontitis by inducing oral microbial dysbiosis and a consequential shift in host metabolism.

Photonuclear Population of 229m,gTh in Th‐Doped Crystals Toward Nuclear Clock Development

Advanced Science, EarlyView.
This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.

Management of Impacted Premolar With Root Dilaceration Caused by Radicular Cyst in Deciduous Molar: A Case Report

Case Reports in Dentistry
Radicular cyst is the most common inflammatory odontogenic cyst in the oral cavity, but it rarely occurs in deciduous teeth. Radicular cysts in deciduous teeth can lead to root dilaceration in permanent successor teeth, resulting in impacted permanent ...

Traumatic intrusion of permanent teeth. Part 1. An epidemiological study of 216 intruded permanent teeth [PDF]

Dental Traumatology, 2006
Abstract –  An epidemiological study of traumatic intrusion of permanent teeth was performed on 216 teeth in 151 patients treated over a 50‐year period at a major trauma center in Denmark (Copenhagen). This analysis showed that intrusion of permanent teeth was of rare injury only affecting 1.9% of traumatic injuries involving permanent teeth.

Clinical and radiographic analysis of traumatized primary teeth and permanent successors: Longitudinal study

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2020
Background: Dental trauma can determine the occurrence of sequelae in the deciduous tooth and due to the anatomical proximity to the germ of the successor permanent tooth, it frequently causes changes to the developing teeth.

Seeing Through the Face: Robust Facial Diagnosis Enhanced by Landmark Detection and Pose Normalization

Advanced Intelligent Systems, EarlyView.
This study proposes a robust, generalizable new approach for facial type diagnosis. Based on landmark detection and pose normalization, a 94.7% diagnostic accuracy is achieved by Combined Heatmap Regression and Coordinate Regression network. This research makes the AI‐generated preliminary diagnosis more interpretable and reducing the impact of ...
