To evaluate the dimensional accuracy of the resultant (duplicative) casts made from two different impression materials (polyvinyl siloxane and polyether) in parallel and angulated implants. ⋯ On the basis of the results of this study, the use of both the impression materials i.e., polyether and polyvinyl siloxane impression is recommended for impression making in parallel as well as angulated implants.

The pterion is a point of sutural confluence seen in the norma lateralis of the skull. The site is an important landmark in surgical approaches to the anterior and middle cranial fossa. ⋯ These findings are important for the surgeon as the pterion junction is a common extracranial landmark in neurosurgical and surgical approaches.

This is a case of a 21-year-old man who presented with history of abdominal pain following blunt abdominal trauma. Although the initial ultrasound scan showed mild free peritoneal fluid, the patient was managed conservatively as a probable case of splenic injury and was discharged in satisfactory condition after 6 days of admission. ⋯ This is a rare condition in which the diagnosis is often delayed or missed as was the case in our patient. To the best of our knowledge, this is the first reported case of isolated gallbladder perforation in Nigeria, and it behooves the clinician to be aware of the likelihood of this condition in patients with blunt abdominal injury.
