There are contradicting data and reports regarding the position of the mandibular lingula in relation to the mandibular foramen and the mylohyoid groove. The current observation attempts to describe the location of the lingula in relation to the mandibular foramen, and the location of the mylohyoid groove in relation to the lingula and mandibular foramen. Fifty adult black Tanzanian mandibles were used in this study. The lingula was observed to belong into 5 major groups based on shape and size as large nodular, small nodular, large triangular, small triangular, and small bony spicule type located anterior or posterior to the mandibular foramen. In 64% (32) of the mandibles the mylohyoid groove originated from the medial wall of the mandibular foramen, at the posterior border of the lingula, in 24% (12) the mylohyoid groove started on medial wall of the mandibular foramen, non-related to the lingula and in 12% (6) at the posterior border of the mandibular foramen. We conclude that in more than half of the adult mandibles the lingula contributes into formation of the anterior half to two third of the medial wall of the mandibular foramen and the mylohyoid groove starts at the posterior border of the lingula. In less than half of the adult mandibles the mylohyoid groove is not related to the lingula starting at the posterior one third of the medial wall or at the posterior border of the mandibular foramen. This implies that the attachment for the sphenomandibular ligament is either on the lingula or on the medial wall of the mandibular foramen or on both leading into variation in the location of the mylohyoid groove.

Osteometric studies of the mandible are useful for identifying polymorphisms that are affected by general factors of anatomical variation, such as breed and gender, but age-related changes have not yet been reported in sheep. Our results showed that the morphometric parameters of the mandible were significantly affected by the age of the lambs. However, at 155 days of age, the mandible already presents all the morphological characteristics observed in adult animals.

Background: The foramen of Huschke (FH) and the petrotympanic fissure (PTF) are anatomical structures that can influence temporomandibular joint disorders (TMD) by potentially affecting the movement and function of the mandibular condyle.

Objective: This study investigates the relationship between patients with TMD and the presence of FH and PTF to enhance diagnostic and therapeutic approaches.

Methods: This retrospective study analyzed cone beam computed tomography (CBCT) images from 212 patients.

: the mandibular foramen is an essential anatomic landmark in performing various dental and surgical procedures, including inferior alveolar nerve block (IANB). However, its position may vary based on the individual morpho-functional features of the skull and face. This study aims to conduct a personalized assessment of the location of the mandibular foramen in various shapes of skulls, faces, and mandibles.

Aim: This study aims to analyze the root canal configuration system of mandibular first premolars in the Bengali subpopulation using cone-beam computed tomography (CBCT).

Materials And Methods: Based on Vertucci's classification, the root canal morphology of 100 randomly selected mandibular first premolars in 56 males and 44 females from the Bengali subpopulation of West Bengal was assessed in vitro. The location of the apical foramen, lateral canal, C-shaped canal, types of canal orifice cross-sections, minor constriction diameter, tooth length, and root length were noted.

Article Synopsis
  • The study explored how mandible measurements can predict height in a Japanese population using 3D CT scans of cadavers.
  • Significant correlations were found between stature and four specific mandibular measurements, with correlation coefficients ranging from 0.668 to 0.705.
  • A regression formula was developed and validated, suggesting that these measurements can be useful in forensic contexts when other methods are not available.
