Tricuspid atresia and Truncus arteriosus were found in 3 children with congenial heart disease each, Shone complex was found in a child, Hypoplastic left heart syndrome was also noted in a child. The incidence of complex congenital heart diseases among prospective Paediatric cardiac surgery patients is high. Efforts should be made to improve access to preventive cardiology in order to curb these diseases.

In children and adolescents, cysts usually grow faster than adults and require much knowledge for diagnoses and treatments. This study aimed to determine the diagnosis and treatment of odontogenic cysts in different age groups by evaluating the type of lesions, age, gender, and anatomical distribution of odontogenic cysts seen in children and adolescents by cone-beam computed tomography. A total of 42 odontogenic cysts (radicular, dentigerous cyst, and odontogenic keratocyst) were determined in children and adolescents aged 7-18 years. Cone-beam computed tomography images of odontogenic cysts were analyzed in terms of types, age, sex, anatomical location, height, width, depth, scalloped borders, lesion shapes, tooth displacement, root resorption, and association with an unerupted tooth. There was a significant correlation between odontogenic cyst types and age groups, scalloped borders, lesion shape, tooth diution and properties of odontogenic cysts in pediatric patients will help diagnose the lesions during clinical and radiological examinations and make appropriate treatment planning.
