Long-term development of malocclusion traits in orthodontically treated and untreated subjects.

Introduction: The purposes of this study were to analyze long-term changes in malocclusion traits and to compare the development in orthodontically treated and untreated subjects.

Methods: The sample comprised 308 adolescents in the intermediate, late mixed, or early permanent dentition who were examined clinically at the ages of 8 to 17 years and again 25 years later.

Methods: This was a consecutive prospective randomized clinical study. In all, 203 patients admitted to two university hospitals with an unstable trochanteric or a subtrochanteric fracture type were included.

Dental anxiety in Iceland: an epidemiological postal survey.

In this study, we examined the prevalence of specific (dental) phobia among a sample of the Icelandic population. In addition to dental anxiety we explored factors that could be related to dental anxiety. In the period 1972-73, a stratified sample of 1641 schoolchildren in Reykjavík was selected for a study on malocclusion, dental maturation and other factors.
