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 ...

A review of implant provision for hypodontia patients within a Scottish referral centre [PDF]

, 2017
Background: Implant treatment to replace congenitally missing teeth often involves multidisciplinary input in a secondary care environment. High quality patient care requires an in-depth knowledge of treatment requirements.

Homo luzonensis and the role of homoplasy in the morphology of hominin insular species

Cladistics, EarlyView.
Abstract Homo luzonensis lived during the upper Pleistocene in the northern Philippines, east of the Wallace line. The few specimens attributed to this species show a mosaic of plesiomorphies for the genus Homo and apomorphies found in upper Pleistocene Homo species.

Implant Placement and Immediate Provisionalization After Alveolar Ridge Reconstruction in the Aesthetic Zone Using a Digital Workflow: A 1‐Year Prospective Case Series Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Introduction In single‐tooth replacement in the aesthetic zone, extensive bone defects require alveolar ridge reconstruction. A digital workflow involving CBCT and intraoral optical scanning enables a three‐dimensional assessment, prosthetically driven implant positioning, computer‐assisted implant surgery, and prefabrication of a temporary ...

Hypohyperdontia: Agenesis of three third molars and mandibular centrals associated with midline supernumerary tooth in mandible

Contemporary Clinical Dentistry, 2010
Agenesis of teeth in a patient who also presents with a supernumerary tooth is one of the rare numerical anomalies in human dentition. Agenesis of third molars was shown to be associated with other missing permanent teeth.

Whole genome sequencing reveals novel non-synonymous mutation in ectodysplasin A (EDA) associated with non-syndromic X-linked dominant congenital tooth agenesis. [PDF]

PLoS ONE, 2014
Congenital tooth agenesis in human is characterized by failure of tooth development during tooth organogenesis. 300 genes in mouse and 30 genes in human so far have been known to regulate tooth development. However, candidature of only 5 genes viz. PAX9,
