Radiographic and imaging diagnosis of rhinolith in dental clinics: a case report

purpose: rhinolith is a calcification that occurs in the nasal cavity and may be discovered during routine radiographic exam. this calcification is rare, generally single, exogenous or endogenous, unilateral, and asymptomatic. it can cause nasal obstruction, fetid odour and purulent secretion. this study reported a case of rhinolith and its radiographic features. case description: a female, 14-year-old patient had a radiopaque mass in the right nasal cavity. the primary treatment plan included oral surgery to remove a supposed impacted supernumerary tooth, which diagnosis was based on conventional radiographic exams. after an unsuccessful surgery, additional exam with computed tomography showed images compatible with a rhinolith. conclusion: computed tomographic scans are required for differential diagnosis of pathologies in the nasal cavity to provide proper treatment.
