Idiopathic coronal resorption in impacted permanent teeth and its relationship with age: radiologic study

Abstract

Purpose The purpose of this study was to evaluate the relationship between idiopathic coronal resorption and age in adult patients. Materials and Methods 3405 digital panoramic radiographs present in the archive of the radiology department belonging to 1584 males and 1821 females aged 25 and over were assessed by two oral and maxillofacial radiologists. The patients' age, gender, number of impacted teeth, number and position of teeth with idiopathic coronal resorption and the extent of coronal resorption were recorded on standard forms. Results A thousand and nine impacted teeth were observed in 622 patients (304 males and 318 females) with a mean age of 36,92 (±10,85). Idiopathic coronal resorption was present in 26 of the 622 patients with a frequency of 4.2%. One patient had two teeth with idiopathic coronal resorption; resulting in as 27 teeth and a frequency of 2.7% according to tooth number. There were 13 (50%) females and 13 (50%) males having idiopathic coronal resorption. There was no significant difference between genders (p>0.05). The presence of idiopathic coronal resorption increased with advanced age (v: 0,193, p<0.05). There was no statistically significant difference between the extent of the coronal resorption and age (p>0.05). Conclusion The presence of idiopathic coronal resorption increases with advancing age. Idiopathic coronal resorption is detected incidentally during radiographic examination. Thus, dentists should consider this situation and should perform periodically radiographic examination of impacted teeth.
