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 ...

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,

Severe hypodontia: identifying patterns of human tooth agenesis [PDF]

The European Journal of Orthodontics, 2010
Tooth agenesis is the most common dental anomaly. The aim of this retrospective study was to identify common patterns of tooth agenesis in a sample of 92 patients (55 females and 37 males; mean age 27.7 years) with non-syndromic severe hypodontia. The Tooth Agenesis Code (TAC) procedure was used for that purpose. The patients in this study were missing

Kdf1 Regulates Molar Cusp Morphogenesis via the PI3K/AKT/mTOR Signalling Axis

Cell Proliferation, EarlyView.
Epithelial Kdf1 knockout disrupts molar cusp morphogenesis by promoting inner enamel epithelium proliferation and invagination via PI3K/AKT/mTOR signalling. ABSTRACT Keratinocyte differentiation factor 1 (Kdf1) reportedly plays a significant role in enamel formation.

Radiographic assessment of agenesis of the third molars: A cross-sectional study

Dentistry and Medical Research, 2023
Congenital absence of a tooth is known as dental agenesis or agenesis of a tooth. Although both deciduous and permanent dentition are prone to agenesis, permanent third molars are the most commonly affected teeth.
