The window approach for extraction of tooth root fragments: a different soft tissue management [PDF]

open access: yes, 2018
Different techniques have been proposed for the removal of the apical portion of fractured teeth. The window approach was proposed in the past to remove a tooth root fragment through a buccal bone opening at the level of fragment.

Biocompatible Multifunctional Polymeric Material for Mineralized Tissue Adhesion

open access: yesAdvanced Healthcare Materials, EarlyView.
A multifunctional thiol‐ene resin system is developed that provides a strong adhesive interface with dentin while maintaining biocompatibility with dental pulp cells. The addition of an acidic monomer to a triacrylate‐trithiol‐based resin achieves over 10 MPa shear bond strength by reinforcing the hybrid interface.

Sharp Curvature of Premolar Resulting in External Apical Root Resorption of the Neighbouring Molar

open access: yesCase Reports in Dentistry, 2011
This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second

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 ...

Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Keratin‐based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin's structural adaptability and mineral ions‐binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a

Human life history evolution explains dissociation between the timing of tooth eruption and peak rates of root growth.

open access: yesPLoS ONE, 2013
We explored the relationship between growth in tooth root length and the modern human extended period of childhood. Tooth roots provide support to counter chewing forces and so it is advantageous to grow roots quickly to allow teeth to erupt into ...
