Abstract
ObjectivesThe aim of this study was to evaluate cases of dental trauma treated at the specialized center of Pontifical Catholic University of Paraná, Curitiba, Brazil, during a period of 2 years.Material and MethodsA total of 647 patients were evaluated and treated between 2003 and 2005. Data obtained from each patient were tabulated and analyzed as to gender, age, etiology, time elapsed after the injury, diagnosis (type of trauma), and affected teeth.ResultsThe results revealed that male individuals aged 7 to 13 years presented the highest prevalence of injury, and falling was the main causal factor. In most cases, the time elapsed between the accident and the first care ranged from 4 to 24 h. A total of 1,747 teeth were affected, with higher incidence of concussion/subluxation and coronal fracture, followed by lateral luxation and avulsion. The permanent maxillary central incisors were the most commonly affected teeth.ConclusionThe frequency and causes of dentoalveolar trauma should be investigated for identification of risk groups, treatment demands and costs in order to allow for the establishment of effective preventive measures that can reduce the treatment duration and costs for both patients and oral health services.
Highlights
Dentoalveolar traumas are observed and treated in dental clinics
Sixty hundred and forty seven patients with dentoalveolar trauma were treated at the Dentoalveolar Trauma Care Service of the Pontifical Catholic University of Paraná, Brazil, between 2003 and 2005
Information referring to gender, age, etiology, period of the year and hour of occurrence, time elapsed after the injury, diagnosis and most affected teeth, were retrieved, plotted and presented in tables for further analysis
Summary
Dentoalveolar traumas are observed and treated in dental clinics. Their severity depends on the energy of impact and direction of the causal agent, as well as on the resistance of the tissues surrounding the traumatized teeth, which are more susceptible at the anterior region[11], along with immunological factors, in cases of avulsion and replantation[15]. Situations such as car, sports and working accidents, and falling are the most common reasons for dental traumatism[7,11,20]. An epidemiological evaluation of patients attending the Dentoalveolar Trauma Care Service of the Pontifical Catholic University of Paraná, Brazil, between 2003 and 2005, was undertaken to better analyze the requirements of emergency assistance
