We report the incidence of retromolar foramen from ninety-four dry mandibles of south-eastern part of Karnataka State, India. The foramen was observed in 11 mandibles out of 94 included in the study (11.7%). In three mandibles, the foramen was present bilaterally (3.2%) and in three it was on the left side (3.2%) and in five it was on the right side (5.3%). For the first time, we also measured the dimensions of the retromolar area and distance of the foramen from third molar tooth to understand its risks during the surgical extraction of the lower third molar tooth.

The larger branches, namely, the inferior gluteal artery, the superior gluteal artery, and the internal pudendal artery, show sufficient regularity in their patterns of origin to allow typing. The variability of the IIA and its branching pattern were studied by dissecting sixty-eight male pelvic halves (34 right and 34 left) and forty-eight female pelvic halves (24 right and 24 left sides). In significant number of specimens, IIA terminated without dividing into 2 trunks as against the usual description. There was also considerable interchange of branches between the 2 terminal divisions. The patterns of branching noted were grouped as per Adachi's classification. The incidence was noted to be as follows: type Ia in 60.6%, type Ib in 2.6%, type IIa in 15.8%, and type III in 21%. The other types were not observed in this study. Conclusion. Interventions in the pelvic region must take into account the variability of the IIA and its branches that can modify the expected relations and may lead to undesired hemorrhagic or embolic accidents.

At the same time, magnetic resonance imaging (MRI) has been introduced as a noninvasive diagnostic technique. The aim of this study was to investigate the anatomy of the lumbar lordosis using midsagittal MRIs. Normal lumbar spine MRIs obtained from 93 individuals (46 males, 47 females; 25-57 years old) were evaluated retrospectively. The lumbar spine curvature and its segments \"vertebrae and discs\" were described and measured. The lumbar lordosis angle (LLA) was larger in females than in males. Its mean values increased by age. The lumbar height (LH) was longer in males than in females. At the same time, the lumbar breadth (LB) was higher in females than in males. Lumbar index (LI = LB/LH × 100) showed significant gender differences (P < 0.0001). Lordosis was formed by wedging of intervertebral discs and bodies of lower lumbar vertebrae. In conclusion, MRI might clearly reveal the anatomy of the lumbar lordosis. Use of LI in association with LLA could be useful in evaluation of lumbar lordosis.

The actual basal bone height of the reconstructed mandible is relevant to achieve normal occlusal vertical dimension for the prosthesis fabricated. The purpose of the study was to determine the mean and baseline values of the occlusal vertical dimension and height of the mandibular basal bone in a Nigerian population. Method. Each participant was asked to bring the upper and lower teeth into contact, while the distance between the nasal sill and dimple on the lower lip was measured (OVD). The skin at lower border of the mandible was marked and the distance between this point and the landmark on the lower lip was measured, MBH. Result. 200 subjects were evaluated.

The present study was conducted from random sampling of University of Port Harcourt students. A total number of 140 subjects (70 Igbos and 70 Ikwerres) of age bracket of 18-30 were used. Results. The different shapes of rugae were obviously observed with varying degrees of predominance among the two tribes. The most predominant patterns are wavy and curvy followed by straight. The Igbos were predominantly wavy while the Ikwerres were predominantly of curve and straight patterns. The Igbo males and females had more wavy pattern with percentage values of 51.6% and 59.9% which is significantly higher in proportion (P < 0.05) as compared to the Ikwerre males and females with percentage values of 35.6% and 40.6%. On the other hand, Ikwerre males and females proved to be curve dominant with percentage values of 45.2% and 34.4% and this showed significant difference in proportion (P < 0.05) as compared to the Igbo males and females with percentage curve values of 27.9% and 26.1%.

The root anatomy of each tooth was evaluated for the following parameters: the pattern of the root canals, anatomic length of the crown and the root, the presence of accessory canals, the shape of the access cavity, the position of the apical foramina, root diameter, and dentin thickness of the root. Results. Majority of the teeth had a Type I canal configuration in both maxillary canines (81.6%) and mandibular canines (79.6%). In maxillary canine the other canal patterns found were Type III (11.6%), Type II (2.8%), Type V (2%), Type XIX (1.2%), and Type IV (0.8%).
