Orthodontic treatment of an impacted dilacerated maxillary incisor: a case report [PDF]
, 2005 Dilaceration is one of the causes of permanent maxillary incisor eruption failure. It is a developmental distortion of the form of a tooth that commonly occurs in permanent incisors as result of trauma to the primary predecessors whose apices lie close ...

Heterogeneity of amelogenin mRNA in the bovine tooth germ. [PDF]
Journal of Biological Chemistry, 1987 The amelogenins are a complex mixture of hydrophobic proteins that are the major organic component of developing enamel. To study the molecular mechanisms underlying the heterogeneity of the amelogenins we isolated cDNA clones encoding these proteins. The clones were definitively identified by hybrid-selected translation experiments and by comparison ...

Periodontology 2000, EarlyView.Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's

A Critical Analysis of the Limitation of Deep Learning based 3D Dental Mesh Segmentation Methods in Segmenting Partial Scans [PDF]
arXiv, 2023 Tooth segmentation from intraoral scans is a crucial part of digital dentistry. Many Deep Learning based tooth segmentation algorithms have been developed for this task. In most of the cases, high accuracy has been achieved, although, most of the available tooth segmentation techniques make an implicit restrictive assumption of full jaw model and they ...

Periodontal and orthodontic management of impacted canines
Periodontology 2000, EarlyView.Abstract The maxillary and mandibular canines are described by many clinicians as the “cornerstone” of the arch. When in their optimal position, they play a critical role in providing a well‐balanced occlusal scheme that contributes toward functional as well as neuromuscular stability, harmony, esthetics, and dentofacial balance.

Evaluation of the effect on the permanent tooth germ and the adjacent teeth by finite element impact analysis in the traumatized primary tooth [PDF]
Background: One of the primary concerns in the paediatric emergencies is traumatic dental injuries. Objective: This study aimed to create trauma in primary teeth and reveal its effects finite element analysis.

Inflammation and mechanical force‐induced bone remodeling
Periodontology 2000, EarlyView.Abstract Periodontitis arises from imbalanced host–microbe interactions, leading to dysbiosis and destructive inflammation. The host's innate and adaptive immune responses produce pro‐inflammatory mediators that stimulate destructive events, which cause loss of alveolar bone and connective tissue attachment.

Graded requirement for the zygotic terminal gene, tailless, in the brain and tail region of the Drosophila embryo [PDF]
, 1988 We have used hypomorphic and null tailless (tll) alleles to carry out a detailed analysis of the effects of the lack of tll gene activity on anterior and posterior regions of the embryo.
