Abstract

Studies have shown that some children and adolescents are effected only once with a dental trauma, while others seem to be accident-prone and suffer from multiple dental trauma episodes (MDTE). Studies have also shown that dental traumas mostly affect upper permanent and medial incisors. Less is known about treatment consequences related to teeth with repeated dental trauma episodes. The aim was therefore to evaluate the risk of MDTE to permanent teeth among children and adolescents by age and gender and to compare types of dental treatment modalities used for patients with one episode and those with MDTE and with single and repeated traumatized teeth. The study was based on a random sample of 83 Danish 6-18-year-old children and adolescents born in 1970 who suffered from dental trauma episodes. All patients were followed during a 12-year period (1976-1988). Forty-one of the patients were registered with MDTE with a range of 2-7 episodes and a mean of 2.9 episodes/patient (SD = 1.1). The mean age at single and MDTE was 11.4 years (SD = 3.6) and 8.6 years (SD = 2.1), respectively. No significant differences were found between age at first episode and the number of MDTE per patient. The number of patients with MDTE was significantly higher among those who suffered their first trauma episode in the age interval 6-10 years than in the age interval 11-18 years (P less than 0.001). A survival analysis showed that the risk of sustaining another trauma episode increased by 14.9-30.3% when the first trauma occurred before the age of 11, compared to 0-7.4% after the age of 10. The risk of sustaining multiple injuries was 8.4 times higher when the first trauma episode occurred at 9 years of age, compared with those occurring at age 12. The survival analysis also showed that for every new trauma episode, the interval between them became closer. Forty-five per cent of the MDTE affected teeth had already sustained an injury. With an increased number of trauma episodes per patient followed an increase in the number of follow-ups, filling therapy, information and prosthetics, whereas the rates of endodontics, surgery, and consultations were unchanged or even decreased.
