Bone-specific median age of hand-wrist maturation from Sudan.

Background: Maturation of bones in the hand-wrist region varies among individuals of the same age and among world groups. Although some studies from Africa report differences to other ethnic groups, the lack of detailed bone-specific maturity data prevents meaningful comparisons.

Aim: The aim of this study was to describe bone-specific maturity for developing hand-wrist bones in individuals in Khartoum, Sudan.

A randomized clinical trial comparing Hall vs conventional technique in placing preformed metal crowns from Sudan.

Despite the high success rates of preformed metal crowns (PMCs) in children no randomized clinical trials compare methods of placement and none describe its use in Africa. Our aim was to compare survival and cost-effectiveness of PMCs placed by conventional techniques (CT) and biological Hall techniques (HT) using a prospective randomized control trial in a general dental practice from Khartoum. One hundred and nine and 103 PMCs were placed in randomly selected children (5-8years) with 1-2 carious primary molars using HT and CT respectively and followed for 2 years.

Skeletal maturity of the hand in an East African group from Sudan.

Objectives: Studies of skeletal maturity from Africa indicate a delay, reflected in a negative relative skeletal age (RSA). This study aims to evaluate the influence of age, socioeconomic status (SES) and nutritional status on skeletal maturation in a large sample of children from North Sudan.

Materials: The sample consisted 665 males and 1018 females from 3-25 years from Khartoum.
