Introduction: The mental foramen (MF) is a bilateral opening localized on an anterior surface of the mandible. A precise location as well as well-defined shape, size, and number of the MF is crucial for different clinical dental procedures. The aim of this study was to determine a size and location of the MF in relation to the lower teeth using the cone-beam computed tomography (CBCT) study.
Material And Methods: In a group of 201 patients (106 males and 95 females) the CBCT images were performed using the GX CB-500 device (Gendex, USA).
Results: No significant differences in values of the horizontal (H) and vertical (V) diameters as well as the H:V ratio on both sides in relation to the age of participants were found. In males both average values of a horizontal diameter (=0.031) and vertical diameter (=0.001) were significantly higher on the right side than in the female subgroup, whereas on the left side only an average value of a vertical diameter was significantly higher in men (=0.006) in comparison to women. Moreover, the H:V ratio was significantly lower in males on the left side (=0.032). There were no significant relationships between age and gender of the patients (>0.05) and the type of mental foramen on the right and left sides.
Conclusions: The application of the CBCT study enabled a precise determination of the shape, size, and position of the mental foramen in relation to the neighboring anatomical structures on a representative group of the Polish patients. The results obtained may contribute to guidelines for dental procedures including anesthesia of the mental nerve and endodontic, implantology, and dental surgery with regard to the location of mental foramen depending on the sex and age of patients.

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.

The position of the mental foramen is reported to change with age. This study aimed to examine age-related changes in the position of the mental foramen in men and women. Among 200 cases (age 21-100 years; 400 foramina) that underwent postmortem computed tomography, 109 (age 21-93 years; 218 foramina) with mandibular first and second premolars were examined using image analysis software to classify the position of the mental foramen according to Fishel's classification, and the χ² test was performed.

Introduction/objective: Trigeminal Neuralgia (TN) is an extremely painful condition without an established treatment other than symptom-suppressive medications or temporary relief from corticosteroid injections. Mesenchymal Stem Cells (MSCs) have demonstrated the ability to enhance healing and reduce inflammation and pain without side effects. Our objective was to evaluate the safety and efficacy of CT-guided foramen ovale MSC injection in the treatment of TN.

Background: The accessory mental foramen is characterized by small foramina in the surrounding area of the mental foramen with communication with the mandibular canal. The aim of this research was to evaluate epidemiological and radiomorphometric aspects of the accessory mental foramen (AMF) using cone beam computed tomography (CBCT) in Brazilian individuals.
Material And Methods: This was a cross-sectional, quantitative, retrospective descriptive study with 250 CBCT scans of dentate individuals in the anterior mandibular region, aged between 18 and 69 years.
