Radiographic study of mental foramen type and position in Bangalore population

Abstract

Background:The mental foramen is defined as the entire funnel-like opening in the lateral surface of the mandible at the terminus of the mental canal. The mental foramen marks the termination of mandibular canal in the mandible, through which the inferior alveolar nerve and vessels pass. Position of the mental foramen is important when administering regional anesthesia. The aim of this study was to determine the most common type and position of mental foramen in Bangalore population using digital panoramic radiographs. Materials and Methods: A total of 100 (50 M and 50 F) digital panoramic radiographs were collected from Department of Oral Medicine and Radiology within age of 15-50 years, type and position of mental foramen was analyzed. Results:The most common occurrence is Type I and position 4 (symmetrical) of mental foramen. Comparison of type in males and females appears significant. Comparison of the position in males and females appears not significant. Conclusion:The following study suggests that clinicians should carefully identify mental foramen thus minimizing complications during implant, orthognathic surgery and treatment of maxillofacial injuries.

Evaluation of the Position of Mental Foramen for Clinical and Forensic Significance in terms of Gender in Dentate Subjects by Digital Panoramic Radiographs

“…23 Panoramic radiographs were utilized in the present study to assess the mental foramen as it provides more wide and reliable field to view anatomy of the mandible as compared with periapical radiographs. Swamy et al 24 also utilized a similar method to commence the study among Table 3: Measurement of distance of superior and inferior border of the foramen in relation to lower border of the mandible Table 4: Comparison of present study with previous literature…”

These changes are accompanied with remodeling of cortex thickness, 30 mental foramen, 31 GA, 29 and ramus during life. 5 The awareness of cortex thickness changes as a screen tool for osteoporosis and T A B L E 2 Mean ± SD of GA, MI, PMI, GI, AGI, RH, and RW values for right side, left side, and average of both sides in the mandible bone…”

Characteristics Vertical Position of Mental Foramen Reviewed by Panoramic Radiography as a Guide in Predicting Individual’s Age on Forensic Odontology Examination

“…For the individuals in their old age, resorption occurred in mandible bone would bring mental foramen closer to alveolar ridge. When all teeth have already fallen off (edentulous), mental foramen would appear quite close to alveolar ridge, even in the quite severe resorption state, which caused mental foramen gone and replaced with concave which located in every surface of mandible [12][13][14][15].…”
