Abstract:
Anatomical changes and ethnic and racial differences in the location and size of the mandibular foramen (MF) can contribute to the inferior alveolar nerve (IAN) block's lower success rate compared to the maxillary nerve block. Furthermore, in the discipline of forensic anthropology, the morphological characteristics of bone are used to differentiate between males and females as well as the ethnic groups to which they belonged. The mandible is the most durable bone in the body and may stay in a well-preserved form for an exceptionally long time. Because of the consistent relationship between the mandibular foramen and the base of the mandible, morphometric analysis frequently makes use of both structures as references. Due to the paucity of osteological research in this area, the purpose of this study was to establish the position and size of the MF and to develop a prediction model for sex determination in Arab Iraqi populations. This retrospective record review utilised cone beam computed tomography (CBCT) scans of respondents from the Arabic communities of Iraq. This research comprised 200 cases, with 100 male and 100, using the RadiAnt DICOM viewer software. The appropriate measurements were viewed and taken. The visibility ratings and dimensions measurements were completed by a single researcher using intra-examiner calibration and inter-examiner calibration. The size, and location of the MF were evaluated for each gender. The records were imported to the SPSS programme and statistically analysed. This study revealed that 77.9% of lingula were located above the occlusal table, whereas 22.1% were located below the occlusal table. The shape and size of MF was seen to vary significantly. For sex prediction, the results showed that it possible to use the mandibular foramen in sex determination. The likelihood of the sex to be males was 3.88 times more than in females for the length of the MF (p 0.024). Furthermore, the likelihood was 1.47 times more than in females for the area of the MF (p 0.042), as it reduced in female cases (B= -0.435). The findings of this study may provide new information on the size and position of the mandibular foramen in the Arabic people of Iraq. There are no previous studies using binary regression model to predict the type of the gender depending on the measurements of the size and location of the MF.
