Intercanthal Distance of a Sudanese Population Sample as a Reference for Selection of Maxillary Anterior Teeth Size

Background: The choice of the size of artificial teeth takes an important place in the removable prosthodontic treatment. However; the standards or proportions commonly used as a guide have been developed mainly on Caucasian populations. Objectives: to investigate the relationship between intercanthal distance and the anterior maxillary teeth size in Sudanese population. Methods: This is a descriptive cross sectional study conducted in 114 subjects; (45 males - 69 females); from Khartoum and Juba Universities. The age range was from 18-46 years. The intercanthal distance (I.C.D) was the measurement taken between the median angles of the palpabral fissure. Maxillary intercanine distance was obtained by measuring a line from the tip of the canine on one side; to the canine on the other side. An electronic digital caliper (Narex - Czechoslovakia) was used for all measurements. Data were analyzed using Person chi-square test. Results: a significant correlation is found between intercanthal distance and maxillary intercanine distance in all subjects (P-value 0.015); and in females who had a (P-value of 0.006).Maxillary intercanine distance may be estimated by dividing I.C.D by factor 0.9. Conclusion: These results could be used as a helpful guide for selection of anterior teeth width in the Sudanese population

Transplant renal artery false aneurysm: case report and literature review

This is a case report of a 59 years old male who had a commercial non-related living renal transplantation for his end stage renal insufficiency secondary to adult polycystic kidney disease. He suffered an immediate and early post-operative bleeding, which was managed conservatively. He was presented at Sultan Qaboos University Hospital four months after his transplant with abdominal pain, nausea, loss of appetite and a rise in serum creatinine levels. Ultrasonography and angiography have shown a 4 cm false aneurysm of the transplant renal artery at the anastomotic site with the external iliac artery. Surgical exploration with resection of the false aneurysm and reanastomosis of the donor renal artery to the external iliac artery was carried out successfully with preservation of the renal allograft. This is a rare case of an extra-renal false aneurysm at the anastomotic site of the transplant renal artery to the external iliac artery four months after renal allotransplantation. Literature review on the management and outcome of false aneurysms after renal transplant was carried out
