Luxation injuries to the permanent dentition in a Norwegian adolescent population and related life course events
Objectives: To assess the prevalence of luxation injuries to the permanent dentition among Norwegian adolescents and the impact of life course events related to moderate and severe luxation injuries.
Methods: A prevalence study, including prospective clinical data, was conducted among 16-year-old high school pupils in the County of Hordaland, Western Norway. All pupils born in 1997 and attending public high schools were invited to participate by responding to an electronically administered questionnaire (SurveyXact, n=5184). The questionnaire collected information on traumatic dental injuries (TDI) and socioeconomic-, biological-, psychosocial- and behavioral indicators. Participants consented to give access to their dental records in the Public Dental Health Service. Information related to TDI to anterior teeth was recorded.
Results: A total of 2055 participants responded to the questionnaire (response rate 40%). Prevalence of TDI was 16.4% (n=338 pupils), of which 189 pupils (9.2%) had experienced different types of luxation injuries (n=364 teeth). Injuries were classified as mild (n=155 pupils), moderate (n=16 pupils) and severe (n=18 pupils). Boys had more luxation injuries than girls (n=108). Luxation injuries acquired in school hours comprised 45.5%. In order to assess the impact of life course events on the severity of luxation injuries (mild vs. moderate to severe), logistic regression analysis was performed with life course indicators having a significant bivariate effect on severity of luxation injuries (p<0.05). The following variables had a significant increased odds ratio (OR) for having experienced moderate to severe luxation injuries: adolescents reporting a high level of agreeableness (OR 6.34, CI: 1.31-30.68), adolescents reporting less than one family vacation per year (OR 4.08, CI: 1.42-11.73) and adolescents reporting low scores on the question regarding agreement towards teachers views (OR 2.74, CI: 1.20-6.29).
Conclusions: Prevalence of luxation injuries in the examined population was 9.2%, of which only 8.5% and 9.5% were classified as moderate and severe, respectively. Socioeconomic and psychosocial life course events were related to severity of luxation injuries.
