The aim of this study was to further define the relationship between cell proliferation and the rate of tooth eruption in the rat incisor. Vinblastine is a drug that blocks cellular mitosis and was used to inhibit cell proliferation in the odontogenic region of rat incisors that were submitted to a shortening treatment or to higher masticatory forces. Male Wistar rats were divided into five groups: normofunctional (control group for incisor eruption), hypofunctional (incisor submitted to…

Evaluation of tooth eruption rate of incisor teeth in rats with estrogen deficiency.

Estrogen deficiency decreases TER in teeth under impeded condition and also increases ERβ gene expression in the odontogenic region of teeth with continuous formation in a rat model.

Adaptive amelogenesis during unimpeded eruption of rat mandibular incisor

The measured length of the secretion zone is in agreement with the observed thickness of enamel (98 µm) in unimpeded incisors, and the reduced eruption rate and the apical shift of the contralateral incisor are probably due to an increased occlusal load.

Effects of loss of occlusal contact on the expression of matrix metalloproteinase‐2, membrane type 1‐MMP, tissue inhibitor of the MMP‐2, eruption rate, organization and resistance of collagen fibers of the rat incisor periodontal ligament

It is concluded that, after incisor eruption, occlusal contact may be an important factor for regulating the remodeling and the physiological resistance of the periodontal ligament against the continuous eruption process observed in rat incisors.

4-Hexylresorcinol Administration Increases Dental Hard Tissue Formation and Incisor Eruption Rate in Rats

Collectively, 4HR administration increased the expression of markers related to dental hard tissue formation and accelerated the eruption rate of incisors in rats.

Doxycycline reduces the expression and activity of matrix metalloproteinase‐2 in the periodontal ligament of the rat incisor without altering the eruption process

The inhibition of M MP-2 by doxycycline, during incisor shortening, was not enough to alter the eruption rate, which suggests that MMP-2 may have an important role in the turnover of extracellular matrix of the periodontal ligament during the tooth-eruption process.

Aberrantly elevated Wnt signaling is responsible for cementum overgrowth and dental ankylosis.

Histological evidence for a dynamic dental battery in hadrosaurid dinosaurs

The first histological study of an entire hadrosaurid dental battery provides a comprehensive look at tooth movement within this complex structure, underscoring the dynamic nature of one of the most unique and complex dental systems in vertebrate history.

Bisphenol A Exposure Disrupts Enamel Formation via EZH2-Mediated H3K27me3

The results demonstrate the essential role of repressive histone modification H3K27me3 in DDE elicited by exposure to an endocrine-disrupting chemical.

Estudo morfológico do efeito do trauma mecânico sobre a amelogênese em incisivos de ratos

 Introdução: A amelogênese compreende a formação do esmalte por células especializadas denominadas ameloblastos. Os ameloblastos secretam proteínas da matriz e são responsáveis pela criação de um…

MT1-MMP expression in the odontogenic region of rat incisors undergoing interrupted eruption

Results indicate that MT1-MMP may have an important role in the process of dental eruption, and was widespread in the dental follicle, in both groups studied (normal and interrupted eruption groups); however a significant decrease in immunostaining was observed in the interrupted eruption group.

It is demonstrated that isolated damage to the PDL retards tooth eruption, supporting the hypothesis which views thePDL as the prime motor pulling the erupting incisor outward.
