DArch: Dental Arch Prior-assisted 3D Tooth Instance Segmentation [PDF]

open access: yesarXiv, 2022
Automatic tooth instance segmentation on 3D dental models is a fundamental task for computer-aided orthodontic treatments. Existing learning-based methods rely heavily on expensive point-wise annotations. To alleviate this problem, we are the first to explore a low-cost annotation way for 3D tooth instance segmentation, i.e., labeling all tooth ...

Photobiomodulation therapy on orthodontic movement: analysis of preliminary studies with a new protocol [PDF]

open access: yes, 2020
This study aimed to investigate the effectiveness of photobiomodulation therapy (PBMT) on the acceleration of orthodontic movements, deriving from its biostimulating and regenerative capacity on soft tissues, consequent to the increase in differentiation,

Effectiveness of 4 Pulpotomy Techniques—Randomized Controlled Trial [PDF]

open access: yes, 2005
Pulpotomy is the accepted therapy for the management of cariously exposed pulps in symptom-free primary molars; however, evidence is lacking about the most appropriate technique.

A Bio‐Inspired Perspective on Materials Sustainability

open access: yesAdvanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Risk prediction model of impacted supernumerary tooth-associated root resorption in children based on cone-beam computed tomography analysis: a case control study

open access: yesBMC Oral Health
Background External surface resorption is pressure-induced resorption and occurs on the external surface of the root, pressure exerted by impacted teeth, is common causes of external surface resorption.

Varanoid Tooth Eruption and Implantation Modes in a Late Cretaceous Mosasaur

open access: yesFrontiers in Physiology, 2016
Erupting teeth are some of the oldest witnesses of developmental processes in the vertebrate fossil record and provide an important resource for vertebrate cladistics.

Retrospective analysis of the correlation between the facial biotype and the inclination of the upper canine cusp axis to the occlusal plane [PDF]

open access: yes, 2016
Permanent maxillary canines are the second most frequently impacted teeth and the prevalence of this clinical condition is estimated to be 1-2% in the general population.

M2 Macrophage‐Derived Extracellular Vesicles Reprogram Immature Neutrophils into Anxa1hi Neutrophils to Enhance Inflamed Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study reveals that M2‐EVs mitigate periodontitis‐induced bone resorption by modulating neutrophil fate. Single‐cell RNA sequencing identified an Anxa1hi neutrophil subpopulation with pro‐reparative properties. M2‐EVs disrupt neutrophil maturation, promoting this subpopulation through key reprogramming genes (Acvrl1, Fpr2). These findings highlight

An evaluation of mesiodentes: A retrospective study with cone-beam computed tomography [PDF]

open access: yes, 2018
Background: The mesiodens, located in the palatal midline between the two maxillary central incisors, is the most common type of supernumerary tooth. The aim of this study was to evaluate the distribution of mesiodentes according to shape, position, and ...

Engineered Tissue Models to Decode Host–Microbiota Interactions

open access: yesAdvanced Science, EarlyView.
Host–Microbiota interactions in the human body. Created in BioRender. Ghezzi, C. (2025) https://BioRender.com/ihivskg. Abstract A mutualistic co‐evolution exists between the host and its associated microbiota in the human body. Bacteria establish ecological niches in various tissues of the body, locally influencing their physiology and functions, but ...
