The prevalence of malocclusion in Maltese schoolchildren as measured by the Index of Orthodontic Treatment Need

Abstract

The Index of Orthodontic Treatment Need (IOTN), a widelyused, standardised epidemiological tool was used to determine the prevalence of malocclusion in Maltese schoolchildren. The use of an internationally-accepted, graded index based on both health and aesthetic scales allows prioritisation of treatment and appropriate direction of resources. Furthermore it allows training curricula to be tailored to the population requirements. This will maximise cost-benefit ratios to the advantage of both the patient and the service provider. This study highlights the similarities and differences between the Maltese and other populations and draws attention to the traits most prevalent for our population.
