Abstract:
The mole snake (Pseudaspis cana) is capable of inflicting unusual bites in defence and during male combat that present as two parallel lacerations. We investigated the dental morphology of the mole snake by making SEM images, and by CT-scanning and digitally reconstructing the skulls of 14 specimens comprising both sexes. The lengths, volumes, shapes and positions of maxillary and dentary teeth were compared within individuals, between individuals, and between sexes. CT reconstructions show the occurrence of large, flat triangular teeth at the posterior end of the maxilla that are angled to po

AbstractAlthough the front-fanged venom delivery system of the Elapidae is believed to be derived from an aglyphous or opisthoglyphous colubroid ancestor, opinion is divided as to the end of the maxilla on which the proteroglyph fang originated. This study was undertaken to determine whether the evolutionary precursor of the proteroglyph fang was (a) a grooved posterior fang which migrated anteriorly, or (b) an enlarged anterior tooth which secondarily developed a groove for the conduction of venom. The surface morphology of the maxillary teeth of colubrid genera was examined using scanning el

Abstract:
In modern dentistry, radiographic imaging is crucial for examining the connection between the maxillary sinus floor and the root apices of the maxillary posterior teeth, particularly when the periapical region is affected by pathology that could result in infectious, inflammatory, or traumatic changes in the maxillary sinus. This study aimed to investigate the prevalence of periapical pathologies in the maxillary posterior teeth and their relationship with maxillary sinus mucosal thickening by using cone-beam computed tomography scans.

The maxillary sinuses are anatomically adjacent to the apices of the maxillary posterior teeth through their lower portion known as the maxillary sinus floor. The aim of this study is to integrate the current state of knowledge based on scientific evidence regarding the clinical significance of maxillary sinus damage following endodontic pathology, and endodontic and implant treatments performed in the posterior maxilla. The data were obtained from articles in the specialized literature using Web of Knowledge Core Collection, Google Scholar, and PubMed databases, and from specialized books. In

To evaluate the mean distance and differences between posterior maxillary teeth and maxillary sinus floor (MSF) concerning the age and gender of the patients, a total of 124 maxillary sinuses and 496 posterior maxillary teeth were randomly selected in 62 cone-beam computed tomography (CBCT) images. Mean distances between posterior maxillary roots (PMRs) from different teeth and the MSF were measured using a calibrated tool in the software. Other relations regarding the gender and age of the patients were determined. The mean root–MSF distances in the right and left first premolars were more si

Introduction: In the last decades the application of the Finite Element Methodology (FEM) has become popular. It can calculate stresses and displacement in complex structures and can anticipate the tissue responses to orthodontic mechanics applied for treating different malocclusions. This study evaluated and compared the stress patterns and teeth displacement with application of 450g of intrusive force bilaterally on maxillary posterior segment utilizing a conventional old method, High-Pull Headgear (HPHG) and a newer method, Infrazygomatic Crestal Bone Screw (IZC-BS) using 3D-FEM.

AbstractThe Common Wolf snake, Lycodon aulicus capucinus, is a species known to feed on durophagous prey such as skinks. Here we examine in detail the dentitional morphology of L. aulicus capucinus to see whether it possesses morphological specialisations for durophagy comparable to those found in other squamates. We find that L. aulicus capucinus has greatly enlarged anterior maxillary teeth, followed by a large diastema. At the diastema, the maxilla is significantly arched. The diastema is followed by a row of small, closely-packed teeth. Finally, after a short second diastema are enlarged,

Abstract:
The mouth forms the beginning of the digestive system. The oral cavity is bounded externally by the lips, laterally by the cheeks, superiorly by the palate, inferiorly by the oral diaphragm, and posteriorly by the isthmus of fauces. Teeth divide the oral cavity into two separate spaces: the oral vestibule and the oral cavity proper. Teeth begin to erupt in humans around the sixth month of life, and the eruption of the 20 deciduous teeth is completed by approximately 2 years of age. Around the age of 6-7, permanent teeth begin to replace deciduous teeth, a process that is typically completed ar

Now you have an understanding of the anatomy of the maxilla and mandible, the TMJs, and jaw musculature, we can examine how these structures work together to produce the complex actions involved in the biting and chewing of food. Technically, incision is biting a piece from a larger chunk of food and mastication is the grinding down of that piece into smaller components and mixing them with saliva. Mastication is often used to cover both actions. Box 26.1 briefly compares the anatomy of the human dentition to that of other mammals. As well as knowledge of the TMJ, muscles of mastication, and o
