N2 - Background/AimPrediction tools are increasingly used to inform patients about the future dental health outcome. Advanced statistical methods are required to arrive at unbiased predictions based on follow-up studies.Material and MethodsThe Internet risk calculator at the Dental Trauma Guide provides prognoses for teeth with traumatic injuries based on the Copenhagen trauma database: http://www.dentaltraumaguide.org The database includes 2191 traumatized permanent teeth from 1282 patients that were treated at the dental trauma unit at the University Hospital in Copenhagen (Denmark) in the period between 1972 and 1991. Subgroup analyses and estimates of event probabilities were based on the Kaplan-Meier and the Aalen-Johansen method.ResultsThe Internet risk calculator shows individualized prognoses for the short and long-term healing outcome of traumatized teeth with the following injuries: concussion, sub-luxation, extrusion, lateral luxation, intrusion, avulsion, crown fractures without luxation, root fractures and avulsion. The prognoses for pulp necrosis, pulp canal obliteration, infection related root resorption, ankylosis, surface resorption, marginal bone loss and tooth loss were based on the tooth’s root development stage and other risk factors at the time of the injury.ConclusionsThis article explains the data base, the functionality and the statistical approach of the Internet risk calculator.
