[The prevalence of malocclusion problems and orthodontic treatment needs in 13 and 14-year old Quebec school children in 1983-1984].
This article details the problems related to occlusion of 13-14 year old Quebec students. The data was derived from a province wide probability sample of 1201 children in 1983-84 using Granger's Orthodontic Treatment Priority Index (TPI). The principal conclusion are: 32% of the children are in Angle's class II; 18% have an overjet of 5 mm and over; 50% have one or more teeth in minor or major displacement; treatment is mandatory or highly desirable for 13.7% and only 2.9% of the students are under treatment. The results are compared to 6 surveys of the same nature.
