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

Abstract:

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.

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 prosthetic treatment of patients with an edentulous maxilla opposing mandibular natural teeth is one of the most challenging endeavors that face clinicians. Occlusal forces from the opposing natural teeth may cause fractures in the maxillary prosthesis and also result in advanced bone loss of the edentulous maxilla. With the presence of extreme gagging reflex, the treatment may become more complicated. This article describes and illustrates the 2-stage surgical and prosthetic treatment of a patient with an edentulous maxilla opposing natural teeth. In the beginning, the patient was treated

This study aimed to evaluate the position of the root apices of the maxillary canines and posterior teeth relative to the maxillary sinus floor in Romanian subjects. Methods: Data for the study were retrospectively obtained from cone-beam computed tomography (CBCT) scans. The evaluation considered the pattern of proximity to the sinus floor for each tooth type, comparisons of the sinus relationships of teet

ABSTRACT Objective: To test the hypothesis that maxillary development may be affected by occlusal support. Materials and Methods: The sample was composed by Wistar rats (5 weeks old) divided into three groups: Control (n = 10), extraction of mandibular molar teeth – left side (n = 10), extraction mandibular molar teeth – left and right sides (n = 10). The rats were sacrificed 8 weeks postextraction. Cone beam computed tomography scan images were taken for posterior measurement of maxillary length and width. Data were analyzed by one-way analysis of variance (Tukey test as post-hoc test). Resul

INTRODUCTION: Patients with dental Class II bialveolar protrusion are generally treated by extracting the four first premolars or two first and two second premolars, and retracting the anterior teeth. This case report describes the treatment of an adult patient with bialveolar protrusion, a Class II canine and molar relationship, and lip protrusion. METHODS: In this patient, the maxillary right second molar (1.7) had to be extracted due to extensive caries. To create sufficient space to retract the anterior teeth, the maxillary right posterior teeth were distalized with a maxillary posterior m

Abstract:

Cholesterol granuloma (CG) is a tissue reaction in response to the accumulation of cholesterol crystals rarely found in the maxillary sinus. The etiopathogenesis of maxillary sinus CG remains unclear. We reviewed the literature and added two new reports of cholesterol granuloma in maxillary sinus related to endodontically treated maxillary posterior teeth. The first report refers to a 45-year-old woman diagnosed with rhinitis, who was submitted to endodontic retreatment of maxillary molar, and subsequently showed maxillary sinus opacity with cystic appearance.

The analysis of the dentiferous bones, in particular of the maxillae of the Caspian whipsnake Dolichophis caspius, reveals the presence of features typical of opisthoglyphous colubroids. Modified teeth are present in the posterior extremities of the maxillae, morphologically different from the anterior ones, from which they are separated by an alveolar diastema. In correspondence of such diastema, the maxillary bone deviates ventrally, positioning the rear teeth inferiorly than the anterior ones. As in other opisthoglyphous species, such characteristics are also visible in the palatomaxillary

The loss of single or multiple teeth in the maxillary posterior region usually leads to alveolar bone resorption, atrophy, and maxillary sinus cavity gasification, resulting in insufficient vertical bone height of the maxillary posterior alveolar bone, which brings great difficulties to tooth implantation. Maxillary sinus floor lifting is an important method to solve the posterior maxillary bone mass deficiency, which can be divided into internal lifting and external lifting.

Abstract:

In patients with missing maxillary posterior teeth, the negative pressure generated by breathing leads to an increase in the gasification of the maxillary sinus cavity, as well as the absorption of alveolar bone due to the lack of physiological stimulation due to missing teeth. This often leads to insufficient bone height during implant restoration in the maxillary posterior tooth area, and maxillary sinus floor elevation surgery can effectively solve this problem. At present, there are two main techniques for lifting the maxillary sinus floor: internal lifting through the top of the alveolar
