An emerging X–ray technology applied in dento–maxillofacial imaging is cone beam computerized tomography (CBCT). CBCT provides 3 –dimensional imaging of more complex and more accurate imaging when compared to conventional and digital radiology.  Accurate information required for diagnosis, treatment planning, and post–treatment evaluation can be gathered with CBCT system available with small field of view images and at low dose. When it comes to pediatric dentistry radiation dose should be considered. Although radiation dose from CBCT is low in comparison to conventional Computerized tomography(CT), radiation risk to patient should be assessed and quantified. This article provides an overview of applications of CBCT in pediatric dentistry.
