Multiple supernumerary teeth are most commonly found in cleidocranial dysplasia. A parallel technique or right angle technique for radiography will result in greater entrance dosage and less dimensional distortion compared to a bisecting angle technique. A radicular cyst contains fluid and can cause cortical bone expansion.
