To evaluate the prevalence, correlation, and differences of C-shaped canal morphology in mandibular premolars and molars by means of cone-beam computed tomography (CBCT). ⋯ Although the prevalence of C-shaped canals is significantly higher in mandibular second molars, they are also found in mandibular premolars but in small percentages. No significant differences were found between both genders and both sides. Since they exhibit unpredictable morphology and differences across the root length, the use of small field CBCT is recommended when such anatomy is presented in a tooth indicated for root canal treatment for better management.

Le Fort I (LI) osteotomy has been used for the correction of dento-facial deformities of the midface. The aim of this study was to determine the effects of advancement and impaction of the maxilla with LI osteotomy on the nasal cavity and septum. ⋯ The influence of maxillary impaction with LI osteotomy on nasal septum deviation was not found significant but maxillary impaction with LI osteotomy significantly increased the nasal cavity width.

The aim of this study was to examine long-term implant success and marginal bone loss (MBL) of dental implants in postmenopausal women with osteoporosis/osteopenia. ⋯ Within the limits of this retrospective study, it can be concluded that postmenopausal osteoporosis/osteopenia does not affect MBL and long-term implant success. The findings suggest that dental implant therapy is a reliable treatment modality in these patients to improve the quality of life by increasing function and aesthetics.

Provision of safe and adequate blood is challenging in our environment due to paucity of voluntary donors as well as inappropriate blood ordering and utilization. The type and screen (TS) method (typing of blood group and screening for antibodies) reduces the demand for blood reservation in hospital blood banks. ⋯ There was improper utilization of blood in elective surgeries. The TS method identified an antibody not detected by ACM. This would have saved N266,000 {$665.9}, and reduced the demand for blood reservation in the bank. Although The TS method was found not to be significantly different in outcome compared to the ACM, it was found to be cost effective.

The present study aimed at assessing two fixed points of reference from where the mesial and distal point of all rugae can be measured so that the exact movement of particular rugae in any direction can be evaluated and assessing the changes in the palatal rugae after orthodontic treatment. ⋯ The triangle created by the three reference points in the technique III was able to identify the changes in the palatine rugae more precisely than the technique I and Technique II.
