An aberrant splice acceptor site due to a novel intronic nucleotide substitution in MSX1 gene is the cause of congenital tooth agenesis in a Japanese family. [PDF]

PLoS ONE, 2015
Congenital tooth agenesis is caused by mutations in the MSX1, PAX9, WNT10A, or AXIN2 genes. Here, we report a Japanese family with nonsyndromic tooth agenesis caused by a novel nucleotide substitution in the intronic region between exons 1 and 2 of the ...

Tooth autotransplantation combined with bone augmentation for reconstruction of the esthetic zone: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Reconstruction of cleft‐associated defects in the anterior maxilla is complicated by deficient hard and soft tissues, scarring, and altered anatomy. This case report describes tooth autotransplantation with simultaneous autogenous bone augmentation for replacement of a congenitally absent maxillary lateral incisor. Methods A 20‐year‐

Orthodontic, regenerative, and implant management of a mandibular anterior defect: 5‐year outcome

Clinical Advances in Periodontics, EarlyView.
Abstract Background Severe alveolar ridge defects in the mandibular anterior region, often associated with congenital tooth absence and subsequent loss of retained primary teeth, present significant challenges for implant rehabilitation. Limited space, horizontal ridge deficiency, and complex site anatomy often require a multidisciplinary approach to ...

Maxillary canine anomalies and tooth agenesis [PDF]

European Journal of Orthodontics, 2005
The aims of the study were to analyse the records of 26 subjects (18 females, eight males) with maxillary canine-first premolar transposition (Mx.C.P1) together with 160 subjects with a palatally displaced canine (PDC) to determine the pattern of tooth agenesis in these cases and to compare them with similar samples reported in the literature. A strong

From ectodermal dysplasia to selective tooth agenesis [PDF]

American Journal of Medical Genetics Part A, 2009
AbstractThe history and the lessons learned from hypohidrotic ectodermal dysplasia (HED) may serve as an example for the unraveling of the cause and pathogenesis of other ectodermal dysplasia syndromes by demonstrating that phenotypically identical syndromes (HED) can be caused by mutations in different genes (EDA, EDAR, EDARADD), that mutations in the

The genetic basis of tooth agenesis: Basic concepts and genes involved

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2011
Tooth agenesis is the most prevalent craniofacial congenital malformation in humans. While tooth agenesis may be associated with several syndromes, non-syndromic hypodontia refers to the congenital absence of a few teeth in the absence of any other ...

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

Epileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

Reassessment of the morphological evidence for hominin hybrids in the Levant Réévaluation des indices morphologiques d'hominines hybrides au Proche‐Orient

Journal of the Royal Anthropological Institute, EarlyView.
The Levantine hominin fossil and archaeological records have played a central role in long‐standing palaeoanthropological debates over origin models and possible interbreeding between Neanderthals (Homo neanderthalensis) and Homo sapiens. Recent research has provided a strong framework for the morphological expectations of recent hybrid ancestry in ...
