Morphometric analysis of lingual foramen on CBCT: A retrospective radiographic study

Abstract

Lingual foramen is an opening present commonly on the lingual aspects of mandible and it is commonly a midline structure. It consists of blood vessels that supply the anterior mandible. This study was conducted with aim of analyzing the location, number, radiographic subtypes and relationship of lingual foramen/foramina with the alveolar crest on Cone Beam Computed Tomography. Double lingual foramen is shown in most of the cases followed by single foramen. In our study, all 104(100%) patients showed median and lingual position of lingual foramen. There was significant difference in single lingual foramen between males and females. Type I lingual foramen was most commonly found followed by type VI. CBCT is advanced and most important diagnostic tool in order to reveal morphological features and normal anatomical variations as it further helps in planning an implant or corrective surgical treatment procedure.

Anatomical evaluation of the medial lingual foramen using cone-beam computed tomography: a retrospective study

“…The occurrence of FSS ranged from 62.0% to 86.8%, while the prevalence of FIS ranged from 13.0% to 83.8%. The differences reflected the different characteristics and populations studied, which included populations from several countries [2,8,13]. The difference between our results and those of other authors may have been because the Brazilian population has a greater miscegenation rate and because our sample was much larger than the sample of other studies.…”

“…Furthermore, for the FIS analyses, most studies did not consider the foramen in other positions as this study did. However, the identification of at least one lingual foramen in the midline of the mandible was possible in most analyses [1,7,8,13].…”

“…The cause of such events has been associated with blood vessels that emerge from the lingual foramen in an intraosseous canal [6]. Cone-beam computed tomography (CBCT) provides high-quality images for the assessment of bone canals, which are not easily seen in panoramic or periapical radiographs [1,[7][8][9].…”

Prevalence and Anatomical Variations in the Mandibular Lingual Canal in a Sample of Egyptian Population Using Cbct: A Cross-Sectional Study

“…In our present study the number of lingual canals ranged from one to six canals, with 5,34,37,23,7,16,19 as their studies had similarly reported at least one lingual foramen in 100% of the examined cases. Approaching almost similar results, De Andrade Santos et.…”

“…al. 202119 (5.77%). While the least prevalent number detected in males was six lingual canals (2.9%) similar to Wang et.…”
