ABSTRACT

Objective: This study aimed to identify possible associations of the presence or absence of posttrauma sequelae with the factors inherent to the traumatized tooth and treatment. Materials and Methods: This retrospective study was performed through the evaluation of records and radiographs of a center of reference for dental trauma between January 2008 and December 2014. The factors were analyzed and associated with posttrauma sequelae, such as pulp necrosis and root resorption. Statistical Analysis Used: A binomial logistic regression model was fit (P < 0.05). Results: In luxations, it was possible to observe 37% pulp necrosis, 16% inflammatory root resorption, and 8% replacement resorption. The binomial logistic regression revealed that male gender (P = 0.0392, odds ratio [OR] = 2.79), avulsion injury (P = 0.0009, OR = 12.27), and elapsed time >16 days between the time of trauma to the beginning of the endodontic treatment (P = 0.0450, OR = 7.53) showed a greater chance of presenting a posttrauma complication. Conclusions: Gender, type of injury, stage of root development, and time after trauma until the beginning of the endodontic intervention were related to the appearance of sequelae.

Key words:

Dental pulp necrosis - dental trauma - tooth resorption
