N2 - Aim: To establish the prevalence of pulp calcifications in 946 patients at the Research and Clinical Center of Dental Trauma in Primary Teeth. Study Design: The clinical and radiographic records of 1,675 traumatized primary teeth were evaluated. Statistical analysis was performed using chi-square and univariate logistic regression. Results: 197 (20.8%) patients showed pulp calcification (PC). A total of 250 (14.9%) calcified teeth were observed. In most teeth, PC appeared within the first 12 months following trauma. PC prevalence was higher in cases of repeated trauma (29.6%) than in single trauma (16.4%), p <0.05, with a 2.14 chance of showing pulp calcification when a child suffered recurrent trauma. Most teeth showing calcified pulp, suffered trauma to the supportive tissue (67.4%), being statistically significant in relation to the trauma to dental tissue (p <0.05). Conclusion: PC is a sequelae in cases of trauma to the primary dentition; teeth that suffered recurrent traumatic injuries show higher risk of presenting.
