Knowledge and practice towards early orthodontic problems among general dentists and paediatric dentists.

Objectives: To assess the knowledge, practice and challenges faced by general dental practitioners (GDPs), paediatric dentists (PDs) and postgraduate paediatric dentistry students (PGPDSs) in diagnosing and managing early orthodontic problems.

Design: Cross-sectional study.

Methods: A total of 159 dentists were enrolled in this study (121 GDPs, 21 PDs and 17 PGPDSs).

A comparative assessment of oral health-related quality of life of children born with orofacial clefts in Sudan and their caregivers'.

Background: Cleft lip and palate(CL/P)is the most common orofacial malformation affecting one in every 700-1000 newborns worldwide. The aim of the study wasto evaluate the impact of CL/P on health- related quality of life (OHRQoL) in Sudanese children and the level of concordance between caregivers' and children and to investigate correlates of the caregivers' perceptions of OHRQoL with that of their children.

Methods: The sample consisted of 75 children with clefts (age range 8-16 years), (46 male, 29 female) and their caregivers' attending University of Science and Technology Dental Teaching Hospital.

Oral Health-Related Quality of Life Among Sudanese Children Treated for Cleft Lip and Palate.

Objective: This study compared the oral health-related quality of life (OHRQoL) among children with a cleft lip with or without a cleft palate (CL±P) and a group of their peers. The reliability of the Arabic version of the Child Oral Health Impact Profile Questionnaire (COHIP) was also assessed.

Design: A cross-sectional study.

Comparing orthodontic bond failures of light-cured composite resin with chemical-cured composite resin: A 12-month clinical trial.

Introduction: In this clinical trial, we evaluated and compared bond failure rates of light-cured composite resin vs chemical-cured composite resin for 12 months.

Methods: Twenty-two subjects (356 stainless steel brackets) were included in this study, and a split-mouth design was used to randomly allocate diagonally opposite quadrants to either chemical-cured (178 brackets) or light-cured (178 brackets) composite resin; the brackets came from the same manufacturer. The survival and failure rates of the brackets were evaluated by the mode of polymerization.

Mixed dentition space analysis in a Sudanese population.

Objective: To test the applicability of the Tanaka and Johnston equation for prediction of the mesiodistal width of unerupted permanent teeth in a Sudanese population and to develop a new prediction equation for this specific population if necessary.

Design: A descriptive, cross-sectional study.

Settings: School-based study.

Mucosal leishmaniasis in a Sudanese patient.

Mucosal leishmaniasis (ML) is an oral disease caused by the parasite Leishmania donovani. The disease has been proven to be pandemic in many areas of the world. It affects young men living in leishmaniasis-endemic areas.

Inheritance of susceptibility to root resorption associated with orthodontic force in mice.

Introduction: External apical root resorption (EARR) is an unwanted sequelae of orthodontic treatment. Genetic factors account for approximately 64% of the EARR variation in humans. Inbred mice offer a model to control the environmental factors and genetic heterogeneity that complicate human genetic studies.
