  • Alterations of temporomandibular disorders before and after orthognathic surgery
  • 2007
  • Ingår i: Angle orthodontist. - : Angle Orthodontist. - 0003-3219 .- 1945-7103. ; 77:4, s. 729-734
  • Forskningsöversikt (övrigt vetenskapligt/konstnärligt)abstract
    • OBJECTIVE: To answer the question whether orthognathic surgery does affect the prevalence of signs and symptoms of temporomandibular disorders (TMDs). MATERIALS AND METHODS: A literature survey in the PubMed and Cochrane Library electronic databases was performed and covered the period from January 1966 to April 2006. The inclusion criteria were controlled, prospective or retrospective studies comparing TMDs before and after orthognathic surgery in patients with malocclusion. There were no language restrictions, and three reviewers selected and extracted the data independently. The quality of the retrieved articles was evaluated by four reviewers. RESULTS: The search strategy resulted in 467 articles, of which 3 met the inclusion criteria. Because of few studies with unambiguous results and heterogeneity in study design, the scientific evidence was insufficient to evaluate the effects that orthognathic surgery had on TMD. Moreover, the studies had problems with inadequate selection description, confounding factors, and lack of method error analysis. CONCLUSION: To obtain reliable scientific evidence, additional well-controlled and well-designed studies are needed to determine how and if orthognathic surgery alters signs and symptoms of TMD.

  • Long-term stability of orthodontic treatment and patient satisfaction : A systematic review
  • 2007
  • Ingår i: Angle orthodontist. - 0003-3219 .- 1945-7103. ; 77:1, s. 181-191
  • Forskningsöversikt (refereegranskat)abstract
    • Objective: To evaluate morphologic stability and patient satisfaction at least 5 years after orthodontic treatment. Materials and Methods: Published literature was searched through the PubMed and Cochrane Library electronic databases from 1966 to January 2005. The search was performed by an information specialist at the Swedish Council on Technology Assessment in Health Care. The inclusion criteria consisted of a follow-up period of at least 5 years postretention, randomized clinical trials, prospective or retrospective clinical controlled studies, and cohort studies, and orthodontic treatment including fixed or removable appliances, selective grinding, or extractions. Two reviewers extracted the data independently and also assessed the quality of the studies. Results: The search strategy resulted in 1004 abstracts or full-text articles, of which 38 met the inclusion criteria. Treatment of crowding resulted in successful dental alignment. However, the mandibular arch length and width gradually decreased, and crowding of the lower anterior teeth reoccurred postretention. This condition was unpredictable at the individual level (limited evidence). Treatment of Angle Class II division 1 malocclusion with Herbst appliance normalized the occlusion. Relapse occurred but could not be predicted at the individual level (limited evidence). The scientific evidence was insufficient for conclusions on treatment of cross-bite, Angle Class III, open bite, and various other malocclusions as well as on patient satisfaction in a long-term perspective. Conclusions: This review has exposed the difficulties in drawing meaningful evidence-based conclusions often because of the inherent problems of retrospective and uncontrolled study design. © 2006 by The EH Angle Education and Research Foundation, Inc.

  • Prevalence of ectopic eruption, impaction, retention and agenesis of the permanent second molar
  • 2007
  • Ingår i: Angle orthodontist. - : Angle Orthodontist. - 0003-3219 .- 1945-7103. ; 77:5, s. 773-778
  • Tidskriftsartikel (populärvet., debatt m.m.)abstract
    • OBJECTIVE: To elucidate the prevalence of ectopic eruption, impaction, and primary and secondary retention as well as agenesis of the permanent second molar (M2) among adolescents. MATERIALS AND METHODS: After a sample size calculation, dental records, including radiographs, of 1543 patients (722 girls and 821 boys), from three clinics in the city of Malmoe, Sweden, were retrospectively analyzed. Series of annual records and radiographs were examined for all patients from 10 to 16 years of age and were carried out during 2004-2006. The prevalence of ectopic eruption, impaction, and primary and secondary retention as well as agenesis of M2s was registered in a standardized manner and according to preset definitions. In addition, the times of emergence of the M2s were recorded. RESULTS: The prevalence of ectopic eruption of M2 was 1.5%, the prevalence of primary retention was 0.6%, and the prevalence of impaction was 0.2%. This means that the overall prevalence of eruption disturbances was 2.3%. In addition, the prevalence of agenesis was 0.8%. The prevalence of ectopic eruption was significantly higher in the mandible. Those patients with eruption disturbances and agenesis of M2 showed significantly delayed eruption of their other M2s compared to the individuals without any eruption disturbances. CONCLUSIONS: The prevalence of eruption disturbances was higher than reported earlier, and, even if the disturbances do not occur frequently, it is important to develop an early diagnosis in order to start the treatment at the optimal time.

  • Pain intensity and discomfort following surgical placement of orthodontic anchoring units and premolar extraction : a randomized controlled trial
  • 2007
  • Ingår i: Angle orthodontist. - : The Angle Orthodontist (EH Angle Education & Research Foundation). - 0003-3219 .- 1945-7103. ; 77:4, s. 578-585
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To evaluate and compare perceived pain intensity and discomfort between the placement of two different orthodontic anchoring units designed for osseointegration and premolar extraction in adolescent patients. MATERIALS AND METHODS: A total of 120 adolescent patients (60 girls and 60 boys) were recruited and randomized into three groups. Group A underwent installation of an onplant, group B installation of an Orthosystem implant, and group C premolar extraction. Pain intensity and discomfort, analgesic consumption, limitations in daily activities, and functional jaw impairment were evaluated the first evening and one week after the intervention. RESULTS: Pain intensity following surgical installation of an onplant was comparable to the pain intensity experienced after premolar extraction, but there was significantly less pain after surgical installation of an Orthosystem implant compared to installation of an onplant (P = .002) or premolar extraction (P = .007). The protective, vacuum-formed stent caused great discomfort, even more discomfort than the surgical sites following installation of the onplant or the Orthosystem implant. CONCLUSION: The Orthosystem implant was better tolerated than the onplant in terms of pain intensity, discomfort, and analgesic consumption and was, therefore, the anchorage system of choice in a short-term perspective.

  • Reliability of a questionnaire assessing experiences of adolescents in orthodontic treatment
  • 2007
  • Ingår i: Angle orthodontist. - 0003-3219 .- 1945-7103. ; 77:2, s. 311-317
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To evaluate the reliability of a questionnaire that assessed the expectations and experiences of adolescent patients about orthodontic treatment. MATERIALS AND METHODS: The study included two groups of patients: 30 consecutive patients (19 girls and 11 boys, mean age 14.6 years, SD 2.3 years) naive to orthodontic treatment, and 30 consecutive adolescent patients (17 girls and 13 boys, mean age 15.1 years, SD 2.0 years) in active orthodontic treatment with fixed appliances in both jaws. A questionnaire comprising 46 items was developed, based upon focus group interviews and previous established questionnaires. The questionnaire covered the following domains: Treatment motivation; treatment expectations; pain and discomfort from teeth, jaws, and face; functional jaw impairment; and questionnaire validity. Internal consistency as well as temporal stability with the test-retest method was investigated. RESULTS: A majority of the questions exhibited acceptable test-retest reliability, and composite scores yielded excellent reliability for all domains. Internal consistency was acceptable and good face validity was found for all domains. CONCLUSION: The questionnaire can be recommended for use in the assessment of expectations and experiences of orthodontic treatment.

  • TMD in relation to malocclusion and orthodontic treatment.
  • 2007
  • Ingår i: The Angle orthodontist. - : The E. H. Angle Education and Research Foundation. - 0003-3219 .- 1945-7103. ; 77:3, s. 542-8
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The aim of this systematic literature review was to evaluate associations between different malocclusions, orthodontic treatment, and signs and symptoms of temporomandibular disorders (TMD). MATERIALS AND METHODS: This review was part of a project at the Swedish Council on Technology Assessment in Health Care focusing on malocclusion and orthodontic treatment from a health perspective. As a first step, the literature was searched in the Medline and Cochrane Library databases from 1966 to May 2003. A later update was made in January 2005. Human studies in English or in Scandinavian languages were included. RESULTS: Associations between certain malocclusions and TMD were found in some studies, whereas the majority of the reviewed articles failed to identify significant and clinically important associations. TMD could not be correlated to any specific type of malocclusion, and there was no support for the belief that orthodontic treatment may cause TMD. Obvious individual variations in signs and symptoms of TMD over time according to some longitudinal studies further emphasized the difficulty in establishing malocclusion as a significant risk factor for TMD. A considerable reduction in signs and symptoms of TMD between the teenage period and young adulthood has been shown in some recent longitudinal studies. CONCLUSIONS: Associations between specific types of malocclusions and development of significant signs and symptoms of TMD could not be verified. There is still a need for longitudinal studies.
