Objective:
The purpose of this study was to assess the need for orthodontic treatment among Nigerian children aged 12-14 years old in Benin City, south-southern region of Nigeria.
Research Design:
The sample consisted of 261 randomly selected school children, 122 boys (47%) and 139 girls (53%) with mean age of 12.9 +/- 0.1. The survey was conducted by clinical examination and both components of the Index of Orthodontic Treatment Need (IOTN) were used to determine the need for orthodontic treatment.
Results:
The results revealed that 50 (19.2%) of the children had a definite need for orthodontic treatment according to dental health component while aesthetic component of IOTN indicated definite need in 12 (4.6%). Increased overjet, severe contact displacements and impeded eruption of teeth were the common occlusal features in the definite treatment need group.
Conclusion:
This study provided data on the need for orthodontic treatment among Nigerian school children which is useful to plan and prioritise orthodontic care and services.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
