Oral PathologyOsteosarcoma typically shows a sunburst pattern with radiopaque strands extending from the cortical plates. This characteristic appearance results from tumor bone formation perpendicular to the cortex, creating spiculated patterns. Other features include Codmans triangle (elevated periosteum) and mixed radiolucent-radiopaque appearance. Cotton wool appearance is seen in Pagets disease, soap-bubble in giant cell granuloma, and discrete radiolucency in benign lesions.

OrthodonticsSupervision of a child's dentition is critical during all developmental stages, but the 7-10 years age range, which is the mixed dentition stage, is a particularly important time for monitoring. This is because it is the period when both primary (baby) and permanent (adult) teeth are present in the mouth. During this stage, children are at risk for various dental problems such as crowding, malocclusion, and the loss of primary teeth that can affect the eruption of permanent teeth.
