We aimed to: (i) study the prevalence of root resorption after luxation or avulsion injuries on permanent teeth referred to our dental clinic over a 3-year period; (ii) study the relationship between type of injury and resultant type of resorption complication; and (iii) evaluate success of treatment protocols for various resorption complications. We observed 1943 patients with dental trauma, aged between 2 and 26 years, referred to the Accident and Emergency Department of the Dental Clinic, University of Brescia, from 1st September 1997 to 31st December 2001. Of these, 261 permanent teeth had sustained luxation (n =188) or avulsion (n = 73) injuries. Permanent teeth luxation and avulsion injuries occurred most often in upper incisors (75%) of patients mostly aged 12-21 years, with males more commonly affected than females (68.3 vs. 31.7%). These cases were followed for 5 years, and complications and response to treatment were recorded. Root resorption was observed in 45 (17.24%) of these cases. Of the 45 cases with resorption, 9 were associated with luxation injury (20%) while 36 (80%) with avulsion. We distinguished 30 cases of inflammatory root resorption (18 transient and 12 progressive) and 15 cases of ankylosis osseous replacement. When resorption was recognized, quick and effective treatment could still result in an excellent functional and aesthetic outcome for these teeth.
