AB Oral  exostoses  are  benign  boney  growths  on  the  mandible  or  hard  palate,  including  tori  and  buccal  exostosis.  Tori  are  benign  nodular  overgrowths  of  cortical  bone,  occurring  in  the  midline  of  the  palate  where  the  maxilla  fuses  (palatinus)  or  on  the  mandible,  typically  on  the  lingual  aspect  of  the  molar  teeth  (mandibularis).  Although  their  physical  appearance  may  be  alarming,  there  is  generally  no  need  for  concern.  Tori  are  covered  by  a  thin  epithelium,  which  is  easily  traumatized  and  ulcerated.  These  ulcerations  tend  to  heal  very  slowly  because  of  the  poor  vascularization  of  the  tori.  Torus  palatinus,  in  particular,  is  slow  growing  and  may  occur  at  any  age;  however,  it  is  most  commonly  noted  prior  to  age  30  in  adults  and  affects  women  twice  as  frequently  as  men.  Buccal  exostoses  are  typically  found  on  the  buccal  surface  of  the  maxillary  or  mandibular  alveolar  ridge  adjacent  to  premolar  teeth.  There  are  a  variety  of  oral  conditions  that  may  be  confused  with  exostoses.  Gingival  fibromatosis,  fibroma  formation  secondary  to  irritation,  granulomas,  abscesses,  and  oral  neurofibromatosis  located  on  the  palate  may  resemble  torus  palatinus.  Nodular  bony  enlargement  in  the  oral  cavity  may  also  result  from  fibrous  dysplasia,  osteomas,  and  Paget  disease.  Oral  malignancies  may  manifest  themselves  on  the  palate  as  primary  lesions,  although  these  are  rare.  Oral  radiographs,  CT  scans,  and  biopsy  may  aid  in  differentiating  these  conditions.
