SILVEIRA, Luiz Fernando Machado et al. Inflammatory root resorption frequency due to trauma in anterior teeth. RFO UPF [online]. 2013, vol.18, n.2, pp. 185-192. ISSN 1413-4012.

Objective: inflammatory root resorption is one of the consequences of dental trauma so its early detection and treatment are crucial in limiting their damage. Thus, this study aimed to investigate the prevalence of inflammatory root resorption in traumatized permanent anterior teeth, relating it to the different types of trauma in support and dental tissues. Subjects and method: data concerning inflammatory resorption were collected from 111 teeth, in medical records of 74 patients of a dental trauma care in UFPel’s Dentistry School, from 2005 to 2011. Gender and age of patients, teeth involved in the trauma, presence or absence of full rooting, and the initial time of root resorption emergence were also registered. Data assessment was performed by descriptive statistics and chi-square test with Yate’s correction, at significance level of 5%. Results: inflammatory root resorption was most frequent in male patients, in upper incisors, in teeth with complete root formation, and in minor injuries of dental and support tissues. Also, the supporting tissues injury presented higher resorption frequency when not combined with dental fractures. The starting time for pathology emergence was within the first thirty days after the trauma. Conclusion: it is important to thoroughly diagnose the trauma in dental tissues to verify the impairment of support tissues, since the proservation of these cases should be systematic and continuous to intercept root resorption.
