Cone Beam CT Diagnostic Role in Pediatric Dentistry

Background and Objective: Cone-beam CT is an emerging imaging technology with a wide range of dentomaxillofacial applications. The use of cone-beam CT for pediatric dentistry remains a sensitive point considering the radiation doses involved .However, for orofacial and jaw bone pathologies and a number of specific indications, 3-D imaging might be justified . Until now, indication-oriented cone-beam CT optimization protocols have not been developed and reports mention inconsistent and insufficient recommendations for reducing radiation doses in children and adolescents.Methods and Materials: This review has been done by searching in electronic data bases including PubMed and using pediatric radiology Pediatric dose limitation in maxillofacial radiology and radiology role in pediatric dentistry as keywords.Finding: cone-beam CT in pediatric dentistry in the literature supports this point of view because 3-D imaging can significantly in crease the confidence and predictability, and decreasing surgical invasiveness.However studies approaching the three-dimensional diagnostic of dental anomalies and its impact in the treatment outcomes are rare. Cone-beam CT is indicated when two- dimensional intra- and extra-oral exams do not answer the diagnostic questions. Panoramic and intraoral radiographs might under- or overestimate the size of the lesions. It is known that 3-D information can provide valuable information regarding the prognosis, improving the predict- ability of the surgery and reducing its morbidity.Conclusion: Although the European evidence-based guidelines providerecommendations for the use of cone-beam CT, the current research evidence levelconcerning the indication in children remains limited.
