Abstract (sommario):

Several growth factors and extracellular matrix molecules, which are expressed during embryonic tooth development, are re-expressed in dental tissues under pathological conditions. Pathological conditions such as caries lesions and dental injuries are often lethal to the odontoblasts, which are then replaced by other pulp cells. These cells are able to differentiate into odontoblast-like cells and produce a reparative dentin. Here we demonstrate the in vivo distribution of several molecules in human permanent teeth under normal and pathological conditions. The intermediate filament protein nes

Abstract (sommario):

Mesenchymal stem cells (MSCs) have proven powerful potential for cell-based therapy both in regenerative medicine and disease treatment. Human umbilical cords and exfoliated deciduous teeth are the main sources of MSCs with no donor injury or ethical issues. The goal of this study was to investigate the differences in the biological characteristics of human umbilical cord mesenchymal stem cells (UCMSCs) and stem cells from human exfoliated deciduous teeth (SHEDs). UCMSCs and SHEDs were identified by flow cytometry. The proliferation, differentiation, migration, chemotaxis, paracrine, immunomod

Abstract (sommario):

Early work on the morphogenesis of hairs and teeth was largely descriptive histology and established the times and order of visible initiation of anlagen and their patterns of development. However, in the last 30 years, many growth factors have been discovered; more recently, their expression during morphogenesis has been determined and immunohistochemistry has enabled the visualization of structural elements of organs. This review is concerned primarily with aspects of these recent phases of research with respect to the formation of hairs and, to a lesser degree, teeth. The expression of seve

Abstract (sommario):

The study of fossilized ontogenies in mammals is mostly restricted to postnatal and late stages of growth, but nevertheless can deliver great insights into life history and evolutionary mechanisms affecting all aspects of development. Fossils provide evidence of developmental plasticity determined by ecological factors, as when allometric relations are modified in species which invaded a new space with a very different selection regime. This is the case of dwarfing and gigantism evolution in islands. Skeletochronological studies are restricted to the examination of growth marks mostly in the c

Abstract (sommario):

Dental enamel is the hardest and most mineralized tissue in extinct and extant vertebrate species and provides maximum durability that allows teeth to function as weapons and/or tools as well as for food processing. Enamel development and mineralization is an intricate process tightly regulated by cells of the enamel organ called ameloblasts. These heavily polarized cells form a monolayer around the developing enamel tissue and move as a single forming front in specified directions as they lay down a proteinaceous matrix that serves as a template for crystal growth. Ameloblasts maintain interc

As yet, no single initiating epithelial or mesenchymal factor has been identified. Axons reach the jaws before tooth formation and form terminals near odontogenic sites. In some specie

Orthodontic treatment, especially during the period of active growth, can significantly affect the development of the jaws and teeth.

However, in cases where we have a lack of space, teeth protrusion or dental asymmetry, and the extraction of permanent teeth is indicated, the damaged molars should be the first option for extraction when premolars are in better condition.

Abstract (sommario):

The Enterococcus faecalis (E. Faecalis) virulence factor plays an essential role in the persistence of root canal infection. Virulence factors of Enterococcus faecalis such as lipoteichoic acid, extracellular superoxide, gelatinase, hyaluronidase, and cytolysin are known to increase the ability of Enterococcus faecalis to induce inflammatory processes, colonization formation, and increase resistance. The virulence factor of E. faecalis is mediated by LTA, which has pattern recognition receptors for cytokine release, bone resorption and triggers apoptosis of osteoblasts, osteoclasts, periodonta

Abstract (sommario):

Objectives. To investigate the root morphology and root canal anatomy of maxillary first premolar using microscopic computed tomography (micro-CT). Methods. 324 maxillary first premolars were collected and scanned. The root and canal diameter, canal wall thickness, root taper, and cross-sectional shapes were determined in the single root with 1 canal (SR1C), single root with 2 canals (SR2C), and 2 roots with 2 canals (2R2C) by micro-CT. Results. The results showed that single-rooted maxillary premolars were more common than other types. The incidence of SR1C, SR2C, and 2R2C reached 25%, 26.39%

Abstract (sommario):

Inflammation in primary teeth (PT) is commonly associated with a lower sensibility to painful stimuli, compared to permanent teeth, and usually leads to late presentation for dental treatment. Data obtained on the molecular assessments of dental pulp and clinical examinations could guide practitioners to conduct precise diagnoses and correct treatments. The aim of our pilot study was to assess the levels of several biomarkers (e.g., mineralization, oxidative stress, and inflammation) in primary teeth. The research included 46 dental pulp specimens collected from the primary teeth of children a

Abstract (sommario):

Background. The timing of eruption of permanent teeth can be a precious help to the pediatric practitioner in identifying an appropriate treatment plan. Usually, it presents a more precise sign of an early or late growth of the child. Aims. It is to determine whether the timing of the permanent teeth eruption in Lebanese pediatric population can be considered as standard Lebanese values, since no other study was previously performed. Materials and Methods. A cross-sectional study is conducted, and the clinical emergence data are collected for a sample of 2317 Lebanese children aged between 5.5

Abstract (sommario):

Teeth and denticles belong to a specialized class of mineralizing epithelial appendages called odontodes. Although homology of oral teeth in jawed vertebrates is well supported, the evolutionary origin of teeth and their relationship with other odontode types is less clear. We compared the cellular and molecular mechanisms directing development of teeth and skin denticles in sharks, where both odontode types are retained. We show that teeth and denticles are deeply homologous developmental modules with equivalent underlying odontode gene regulatory networks (GRNs). Notably, the expression of t
