Dentoalveolar Changes in the Premolar Region After Two Maxillary Expansion Protocols

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives To evaluate the dentoalveolar effects on the upper first premolars after two maxillary expansion protocols—rapid maxillary expansion (RME) and alternate rapid maxillary expansion and constriction (Alt‐RAMEC)—before and 6 months after treatment.

Small RNAs and tooth development: The role of microRNAs in tooth agenesis and impaction. [PDF]

J Dent Sci
Tooth development, or odontogenesis, is a complex process in which several molecular pathways play a key role. Recently, microRNAs, a class of approximately 20-nucleotide small RNA molecules that regulate gene expression, have been implicated in the odontogenesis process.

Evaluation of Eruption Pattern of Second Permanent Molars Following Extraction of Compromised First Permanent Molars in Children and Its Predicting Factors: A Retrospective Radiographic Study

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives To evaluate eruption pattern, in terms of space closure and alignment of second permanent molars (SPM), following extractions of first permanent molars (FPM) and assess the effect of predicting factors including age at extraction, developmental stage of SPM, angulation of adjacent teeth and presence of third permanent molars (TPM ...

The WNT10A Gene in Ectodermal Dysplasias and Selective Tooth Agenesis [PDF]

, 2014
Mutations in the WNT10A gene were first detected in the rare syndrome odonto-onycho-dermal dysplasia (OODD, OMIM257980) but have now also been found to cause about 35-50% of selective tooth agenesis (STHAG4, OMIM150400), a common disorder that mostly ...

Oral Manifestations of Non Vascular Ehlers‐Danlos Syndrome Cross‐Sectional Study

Oral Diseases, EarlyView.
ABSTRACT Background Ehlers–Danlos syndromes are rare hereditary connective tissue disorders; however, their oral manifestations remain poorly characterized in molecularly confirmed individuals. The aim of this study was to describe the oral phenotype of patients with non‐vascular Ehlers‐Danlos syndromes compared to healthy controls.

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.

Molecular and Genetic Basis of Non-Syndromic Tooth Agenesis

, 2015
Background: Tooth agenesis represents the most common anomaly of dental development, which according to Online Mendelian Inheritance in Man (OMIM) database, affects approximately 20% of the population.

Whole-Exome Sequencing Identifies Novel Variants for Tooth Agenesis

, 2018
Tooth agenesis is a common craniofacial abnormality in humans and represents failure to develop 1 or more permanent teeth. Tooth agenesis is complex, and variations in about a dozen genes have been reported as contributing to the etiology.
