Abstract [en]

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 < 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.

Abstract [en]

Background: Dental trauma occur in childhood and adolescence with consequences in time and costs for both patient and family. The scientific knowledge of these matters is scarce. For some individuals, dental trauma will result in long, time-consuming and costly treatments in childhood which will continue into adulthood.

Aim: The thesis aimed to increase the knowledge of incidence, risk, treatment, time and costs spent on dental traumas to primary and permanent teeth in children and adolescents.

Material and method: The material for the studies emanated from the county of Västmanland, Sweden, and the municipality of Copenhagen, Denmark, and from a Swedish nation-wide material (Folksam). The material was collected from accident reports, dental files, dental trauma forms, questionnaires and telephone interviews. Descriptive, prospective and analytical methods were used. A classification of uncomplicated and complicated dental traumas was presented.

Results: The incidence of dental trauma to boys was higher, compared to girls, in the county of Västmanland in almost all age groups. For both sexes, the first years in life and the first years in school were the most accident prone periods with incidence twice as high as the average incidence for all children and adolescents in the county. Every third trauma was complicated with injuries to the pulp or periodontal ligaments. Every second patient with a dental trauma to permanent teeth suffered from multiple dental trauma episodes (MDTE) during a period of 12 years. In almost every second patient with MDTE, at least one of the affected teeth had sustained repeated trauma episodes. The risk of sustaining MDTE increased when the first trauma episode occurred in the age interval of 6-10, compared to 11-18 year olds. During a 12-year period, treatment times for complicated traumas were 2.0 and 2.7 times higher for primary and permanent teeth, respectively, compared to corresponding values for uncomplicated traumas. On average, direct time (treatment time) represented 11% and 16% of the total time, while the direct costs (health are service, transport, loss of personal property and medicine) represented 60% and 72% of the total costs of traumas to primary and permanent teeth, respectively, during a 2-year period for cases of a nation-wide material.

Conclusion: Dental traumas are frequent and some individuals are injured several times. Besides treatment time, efforts from the family are substantial in time and costs. Parameters such as degree of severity, access to treatment and place of injury are of major importance to both patient and family and should be considered when calculating time and costs of dental trauma in children and adolescents.
