Abstract
Various diseases occur in the stomatognathic system, and performing a definitive diagnostic examination with histopathology is important in diagnosing the condition and establishing a treatment plan. We investigated 89 patients who underwent histopathological examination at our hospital between January 2013 and December 2014. The number of histopathological examinations increased from 32 in 2013 to 57 in 2014. Of these, cases referred by a local dentist increased from 6% in 2013 to 29% in 2014. Most patients were in their 40s and 70s, forming a binomial distribution. We then investigated all cases classified as neoplastic lesions, cystic lesions, inflammatory lesions or other disease. Neoplastic lesions accounted for 40%, cystic lesions 24%, other diseases 24%, and inflammatory lesions 12%. Among neoplastic lesions, odontogenic malignant tumors were 0%, odontogenic benign tumors 3%, non-odontogenic malignant tumors 11%, and non-odontogenic benign tumors 86%. Among the non-odontogenic benign tumors, fibromas were found to be the most common. Among cystic lesions, 8 patients had radicular cysts and 2 had dentigerous cysts. The most common inflammatory lesion was granulation tissue. The most common other disease was lichen planus. This study revealed trends in histopathological examinations within our hospital department.
