Apical pathological root resorption in primary teeth: retrospective study

Abstract

Aim and objectives: to assess the changes in speed of the apical pathological root resorption and its causes in a group of Romanian children from Bucharest treated at the Paediatric Dentistry Department. Material and methods: The retrospective study was carried out on the OPG of 94 Romanian children aged between 3.5 and 13.58 years, mean age 8.00±0.20 years and on 1137 primary teeth. Results: The apical root resorption represented 93.1% from the teeth with external root resorption. Early root resorption was present in 15.4%, while the late root resorption in 6.5%, of the teeth. Pulpal and periapical infection were the most encountered (8%) causes of the accelerated root resorption. Conclusions: Accelerated root resorption was the most common change in the rate of root consumption recorded in primary teeth and its main cause being the pulpal complications of the untreated caries and trauma.
