THE PATTERN OF PATHOLOGICAL ROOT RESORPTION IN PRIMARY TEETH: RETROSPECTIVE STUDY

Aim of the study: To assess the prevalence of the modified pattern of the root resorption in primary teeth and its causes in a group of Romanian children. Material and methods: The retrospective study was carried out between 2016 and 2017 at the Paediatric Dentistry Department. The patients study sample contained 94 Romanian children (46 girls and 48 boys, aged between 3.5 and 13.58 years, mean age 8.00±0.20 years) and a primary teeth sample of 835. Results: From the total amount of teeth with pathological root resorption pattern, 72.7% were affected by external root resorption, while 36.4% were affected by internal root resorption. Half of the pathological alterations of root resorption pattern were caused by vicinity pressures. Conclusions: The pathological alterations of root resorption pattern were represented especially by external root resorption. An important cause of pathological root resorption pattern was represented by necrosis and apical periodontitis.
