Longitudinal trends in temporomandibular joint disorder symptoms, the impact of malocclusion and orthodontic treatment: A 20-year prospective study.

Background: Studies on the association between malocclusion and temporomandibular joint disorder (TMD) have reported conflicting results.

Objectives: To determine the impact of malocclusion and orthodontic treatment on symptoms of TMD.

Methods: At 12 years, 195 subjects fulfilled a questionnaire regarding TMD symptoms and participated in an oral examination including preparation of dental casts.

Outcome quality and long-term (≥15 years) stability after Class II:2 Herbst-multibracket appliance treatment in comparison to untreated Class I controls.

Aim: To investigate the outcome quality and the long-term (≥15 years) post-treatment (Tx) changes after Class II:2 Herbst-multibracket appliance (MBA) Tx.

Subjects And Methods: In this longitudinal observational study, a recall of Class II:2 patients who had been treated by a Herbst-MBA during adolescence was conducted. Study models from before and after active Tx, after retention and after recall were assessed using standard occlusal variables and the peer assessment rating index (PAR).

Long-term (≥15 years) post-treatment changes and outcome quality after Class II:1 treatment in comparison to untreated Class I controls.

Aim: To investigate the long-term (≥15 years) post-treatment (Tx) occlusal changes and outcome quality after Class II:1 Tx.

Subjects And Methods: Herbst-MBA Tx had been performed at age 12.8 ± 2.

Outcome and long-term stability of an early orthodontic treatment strategy in public health care.

Our aim was to evaluate the long-term treatment outcome of a systematically applied orthodontic screening and early treatment strategy in a public dental health care system, with special reference to occlusal stability at least 5 years post-retention. The subjects (N = 68) belonged to one age cohort born in a Finnish rural municipality (N = 85), and they were regularly followed from 8 to 20 years. Persons with malocclusions were screened and treated according to pre-planned protocol.

The objective and subjective outcome of orthodontic care in one municipal health center.

Objective: The aim of this study was to assess the outcome of orthodontic care in one municipal health center.

Materials And Methods: The material consisted of one age-cohort of 15-16 year-old adolescents (n = 67). Of them, 97% participated in a clinical examination.

Dental arch width, overbite, and overjet in a Finnish population with normal occlusion between the ages of 7 and 32 years.

The aims of the present study were to provide data on growth changes in the dental arches from age 7 to 32 in Finns with untreated normal Angle Class I occlusions. The material consisted of 33 series of dental casts of 18 women and 15 men. The subjects had been examined and study models taken at the ages of 7, 10, 12, 15, and 32.

Orthodontic treatment need from eight to 12 years of age in an early treatment oriented public health care system: a prospective study.

The aim of this study was to investigate the effects of an early treatment oriented orthodontic program on treatment need at age 12 years in a public health care system. The subjects consisted of one whole age cohort in a municipality in Finland, 87 children in total. All children were examined at ages eight, 10, and 12 years.
