PurposeThe purpose of this study was to evaluate the relationship between idiopathiccoronal resorption and age in adult patients.Materials and Methods3405 digital panoramic radiographs present in the archive of the radiologydepartment belonging to 1584 males and 1821 females aged 25 and over wereassessed by two oral and maxillofacial radiologists. The patients’ age, gender,number of impacted teeth, number and position of teeth with idiopathic coronalresorption and the extent of coronal resorption were recorded on standard forms.ResultsA thousand and nine impacted teeth were observed in 622 patients (304 males and318 females) with a mean age of 36,92 (±10,85). Idiopathic coronal resorption waspresent in 26 of the 622 patients with a frequency of 4.2%. One patient had twoteeth with idiopathic coronal resorption; resulting in as 27 teeth and a frequency of2.7% according to tooth number. There were 13 (50%) females and 13 (50%) maleshaving idiopathic coronal resorption. There was no significant difference betweengenders (p>0.05). The presence of idiopathic coronal resorption increased withadvanced age (v: 0,193, p<0.05). There was no statistically significant differencebetween the extent of the coronal resorption and age (p>0.05).ConclusionThe presence of idiopathic coronal resorption increases with advancing age.Idiopathic coronal resorption is detected incidentally during radiographicexamination. Thus, dentists should consider this situation and should performperiodically radiographic examination of impacted teeth.
