Dr. Mupparapu’s initial research included soft tissue calcifications of the maxillofacial region and remote dental consultation (RCDS). He published many articles in the peer-reviewed dental literature on the subject of transmigration of teeth. The classifications he and his co-workers proposed for both unilateral and bilateral transmigratory mandibular canines has been widely accepted and followed universally. He continues to work on the subject to further his knowledge on the mechanisms of altered eruption and transmigration of teeth. Technology related projects are of special interest to Dr. Mupparapu. During the past decade, Dr. Mupparapu was involved in various projects that involved local area and wide area networks that were mainly focused on telecommunications in dental setting, data storage and remote retrieval of radiographs, redundant arrays of inexpensive disks (RAID) and wireless acquisition of radiographic image data. This work led to several peer-reviewed and indexed publications. Cone beam CT and its applications to implant site evaluation is another subject Dr. Mupparapu is currently working on. His special interest is in the utilization of information pertaining to the density values (Hounsfield number) and their reliability for the bone density measurements in the mandible and maxilla. Dr. Mupparapu continues to work in the field of genetics and tooth migration and has actively collaborated with researchers at the University of Malta. He has started several educational research projects in the area of radiation dose reduction, radiographic re-exposures and quality control in Oral and Maxillofacial Radiology.
