The extent of anomalies and developmental aberrations in hemifacial microsomia (HFM) have not yet been fully delineated. Thus, the developmental pattern of the dentition in patients with HFM remains unclear. This study was conducted to investigate the development of the dentition in subjects with varying degrees of HFM and to compare the affected side with the unnaffected side and with data fro...

background and aims. hypodontia is a common developmental abnormality of dentition. this study aimed to determine tooth width in patients affected with mild hypodontia and compare the results with a control group without tooth agenesis. materials and methods. the orthodontic records of 25 patients with congenital missing of one or two teeth (hypodontia group), and 25 subjects with full dentitio...

Correction for 'Nanoparticle-based photoacoustic analysis for highly sensitive lateral flow assays' by Yunfei Zhao et al., Nanoscale, 2016, 8, 19204-19210.

For many years the molecular mechanisms governing bone morphogenetic protein 4 (Bmp4) expression in tooth bud mesenchyme could be explained by an uncomplicated model involving the interaction of the homeobox gene Msx1 and the paired domain gene Pax9 and a limited proximal promoter segment of Bmp4. New insights have led to major revisions, but we are still far from understanding the role of Msx1...

Missing of mandibular second premolar is one of the most common types of tooth agenesis. In such cases, maintenance of the primary second molar, if possible at all, can prevent many treatment procedures in future. The present case report represents the endodontic management of a necrotic left mandibular primary second molar that had developed an abscess. Considering the missing of the permanent...
