We report a rare case of an association of external enamel pearl with internal enamel pearl on the root of a molar. To the best of our knowledge, association of external and internal enamel pearls has not been previously reported. We discussed the histogenesis of enamel pearls and proposed that internal enamel pearl formation may be a continuation of formation of external enamel pearl.

The finite element method (FEM) is an advanced numerical technique that can be applied in orthodontics to study tooth movements, stresses, and deformations that occur during orthodontic treatment. It is also useful for simulating and visualizing the biomechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios. The objective of this research was to analyze the mechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios.

The Grotte du Bison, in Arcy-sur-Cure (Yonne, France), yielded a large assemblage of 49 Neandertal remains from late Mousterian layers, offering critical insights for the study of Middle to Upper Paleolithic populations of Western Europe. Previous studies described the external morphology of 13 isolated teeth and a partial maxilla. Building on this previous work, the current study provides further descriptions and analyses of the remains, including one postcranial fragment, six cranial fragments, two maxillary fragments, and 40 isolated teeth.

The Aim Of The Study: Was a comparative analysis of the structural features of the endodontic system and the thickness of hard dental tissues over the past ten centuries.
Materials And Methods: 180 teeth of people who lived from the X to XX centuries AD were studied using cone-beam computed tomography in endodontic mode: the volume of the endodontic system and the thickness of hard dental tissues were calculated using the algorithm developed by us. The Pearson correlation coefficient and Student's t-test were calculated in Excel program, and the data was analyzed with GraphPad Prism 8 Statistics Guide statistical program.

Background: Odontogenic cysts of the jaws are pathologies that require timely recognition and management. The initial diagnosis is based on clinical and radiographic appearance and dental history. A variety of surgical treatments are used for odontogenic keratocyst (OKC) depending on the clinical and radiographic presentation.

Osteogenesis imperfecta, a common genetic connective tissue disorder affecting bone with multisystemic implications, is caused by genomic alterations at various levels that disrupt the biosynthesis stages of collagen Type I. This study evaluated the intraoral and clinical findings of 43 OI cases in relation to genetic variants, aiming to contribute new insights into the roles of collagen and non-collagen genes in the oral-dental pathology of OI. Significant associations were found between OI variants and dental anomalies such as dentinogenesis imperfecta, enamel hypoplasia, taurodontism, and hypodontia.
