Cleidocranial dysplasia (CCD) it is an autosomal dominant skeletal dysplasia caused by mutation in CBFA1 (Core Binding Factor Alpha), a member of runt family of transcription factors mapped to chromosome 6p21. Radiographic images are important tools for the diagnosis of CCD. On dental radiographs, it is possible to observe 2 features of the classical triad of CCD: multiple supernumerary teeth; and open sutures and fontanelles of the skull. Third important feature hypoplasia of clavicles need additional chest radiograph. Most of mid-facial features of this syndrome can be visualized on CBCT images which save patient from exposure to different views of 2 dimensional imaging required to see widespread involvement of skull but also help in treatment planning for missing permanent teeth including accurate study of the morphology, location, alignment, proximity of teeth to structures like inferior alveolar canal and maxillary sinus well as the quality and quantity of basal bone available which could help a great deal in orthodontic planning, surgical extraction and prosthetic rehabilitation. Considering its valuable importance, CBCT is advisable in all such syndromes with multiple impacted teeth for diagnosis and treatment planning.
