Radix entomolaris and radix paramolaris: A cone-beam computed tomography study of permanent mandibular molars in a large sample from Slovenia.

Objectives: To investigate the prevalence, unilateral/bilateral concurrency, and external morphology of permanent mandibular molars (PMMs) with radix entomolaris (RE) and radix paramolaris (RP) in a sample from Slovenia.

Design: Medium field-of-view cone-beam computed tomography images of 1315 participants (681 males, 634 females) aged 13-90 years (mean age 45.5) were retrospectively examined.

Dental ancestry estimation in a 1500 years old human skeleton from Slovenia using a new web-based application rASUDAS.

The present study was performed on a skeleton excavated from the Late Roman Period necropolis in Ptuj, Eastern Slovenia. Previous anthropological analysis has revealed that the skeleton belongs to a male, who died in his early twenties; however, determination of ancestry was problematic. The skull displays artificial cranial deformation of circular fronto-occipital type and shows some Asiatic anthroposcopic features.

On the appendicular anatomy of the xiphosurid Tachypleus syriacus and the evolution of fossil horseshoe crab appendages.

Xiphosurida-crown group horseshoe crabs-are a group of morphologically conservative marine chelicerates (at least since the Jurassic). They represent an idealised example of evolutionary stasis. Unfortunately, body fossils of horseshoe crabs seldom preserve appendages and their associated features; thus, an important aspect of their morphology is absent in explorations of their conservative Bauplan.

The role of clinical examination in the detection of permanent maxillary molars with two palatal roots.

Background: The aim of the study was to determine whether the presence of two palatal roots (2PR) in permanent maxillary molars (PMMs) could be predicted by observing dental morphological traits during the clinical examination.

Materials And Methods: A total of 18 second and 26 third PMMs with 2PR were examined from the collection of extracted teeth. The reference sample of 44 extracted PMMs with one palatal root was selected such that pairs of morphologically matching PMMs with one and 2PR were formed.

Painful neuropathy caused by compression of the inferior alveolar nerve by focal osteosclerotic lesion of the mandible: A case report.

Osteosclerotic lesions are a common finding on dental radiographs. They are considered developmental variants of a normal bone architecture and they usually do not need any treatment. The purpose of this article is to present a rare case of osteosclerotic lesion of the mandible causing trigeminal neuropathy by compression of the alveolar nerve.
