A 20-year-old man has been our patient irregularly since the age of 13.  His mother initially reported that he did not brush well, probably related to gag reflex.  Panoramus is taken at the ages of 16 and 20 (Fig.1,2).  In fact a dentigerous cyst forms (Fig.1) before calcification of the impacted upper right 3rd molar (Fig.2).
