  • TMD in relation to malocclusion and orthodontic treatment.
  • 2007
  • Ingår i: The Angle orthodontist. - 0003-3219. ; 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.

  • General practice dentists' knowledge of temporomandibular disorders in children and adolescents.
  • 2007
  • Ingår i: European journal of dental education : official journal of the Association for Dental Education in Europe. - 1396-5883. ; 11:4, s. 216-21
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: The aim of the study was to map general practice dentists' (GPDs) knowledge of temporomandibular disorders (TMD) in children and adolescents. Materials and methods: A questionnaire was mailed to 286 Swedish dentists in the Public Dental Service and 17 TMD specialists with documented research experience. The questionnaire contained 37 statements on aetiology, diagnostics, classification, chronic pain and pain behaviour, treatment, and prognosis. Each statement was judged on a 0-10 point scale with the endpoint definitions agree or disagree. Results: The overall response rate to the questionnaire was 87%. In 28 of all 37 statements, the TMD specialists endorsed a consensus, i.e. > 75% of the specialists had the same opinion about the statement. TMD specialists differed most in opinion in the domain diagnostics and classification. In 65% of the statements, differences in knowledge between GPDs and TMD specialists were non-significant. The greatest number of significant between-group differences was found in the domain treatment and prognosis. Most of these statements were related to morphological factors. Conclusion: There is a high degree of consensus in TMD knowledge amongst the TMD specialists and a high degree of agreement in knowledge between GPDs and TMD specialists. In some areas, however, TMD specialists still need to reach a consensus which is founded on evidence-based TMD knowledge in children and adolescents and that can be used in undergraduate teaching. It is therefore important to develope and strengthen the undergraduate dental teaching in TMD and orofacial pain.

  • Response to alkaline stress by root canal bacteria in biofilms. Viability and mechanisms of response to alkaline stress by selected root canal bacteria.
  • 2007
  • Ingår i: International endodontic journal. - 0143-2885. ; 40:5, s. 344-55
  • Tidskriftsartikel (refereegranskat)abstract
    • To determine whether bacteria isolated from infected root canals survive alkaline shifts better in biofilms than in planktonic cultures. METHODOLOGY: Clinical isolates of Enterococcus faecalis, Lactobacillus paracasei, Olsenella uli, Streptococcus anginosus, S. gordonii, S. oralis and Fusobacterium nucleatum in biofilm and planktonic cultures were stressed at pH 10.5 for 4 h, and cell viability determined using the fluorescent staining LIVE/DEAD BacLight bacterial viability kit. In addition, proteins released into extracellular culture fluids were identified by Western blotting. RESULTS: Enterococcus faecalis, L. paracasei, O. uli and S. gordonii survived in high numbers in both planktonic cultures and in biofilms after alkaline challenge. S. anginosus, S. oralis and F. nucleatum showed increased viability in biofilms compared with planktonic cultures. Alkaline exposure caused all planktonic cultures to aggregate into clusters and resulted in a greater extrusion of cellular proteins compared with cells in biofilms. Increased levels of DnaK, HPr and fructose-1,6-bisphosphate aldolase were observed in culture fluids, especially amongst streptococci. CONCLUSIONS: In general, bacteria isolated from infected roots canals resisted alkaline stress better in biofilms than in planktonic cultures, however, planktonic cells appeared to use aggregation and the extracellular transport of specific proteins as survival mechanisms.

  • Dental fear/anxiety and dental behaviour management problems in children and adolescents: a review of prevalence and concomitant psychological factors.
  • 2007
  • Ingår i: International journal of paediatric dentistry / the British Paedodontic Society [and] the International Association of Dentistry for Children. - 0960-7439. ; 17:6, s. 391-406
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: The objectives of this article were to examine the literature published from 1982 to 2006 and to evaluate prevalence of dental fear and anxiety (DFA) and dental behaviour management problems (DBMP) in children and adolescents, and their relationships to age, sex, general anxiety, temperament, and general behavioural problems. METHODS: A broad search of the PubMed database was performed using three combinations of search terms. RESULTS: A large proportion of the identified articles could not be used for the review owing to inadequate endpoints, measures or poor study design. Thirty-two papers of acceptable quality were identified and reviewed. The prevalence of both DFA and DBMP were estimated to 9%, with a decrease in prevalence with age. DFA/DBMP were more frequent in girls. DFA/DBMP were related to general fear and both internalizing and externalizing behavioural problems, although these relationships were not clear-cut. Temperament was related to both DFA and DBMP but with different temperamental characteristics, while general behavioural problems mainly correlated with DBMP. CONCLUSIONS: DFA/DBMP are common, and several psychological factors are associated with the development of these problems. In order to better understand these relationships, a number of issues concerning design of research and measurement of DFA/DBMP have to be dealt with.

  • Using the internet to find offline sex partners
  • 2007
  • Ingår i: CyberPsychology & Behavior. ; 10, s. 100-107
  • Tidskriftsartikel (refereegranskat)abstract
    • We aimed to expand upon the demographic characteristics and gender differences among those who have met someone on the Internet who they later met offline and had sex with as well as any relationship with cybersex, sexually transmitted infections, and online sexual problems. We analyzed data collected through an online questionnaire in 2002 in Sweden including a total population of 1836 respondents of which 1458 used the Internet for sexual purposes. Of those, 35% men and 40% women reported to have met offline sex partners online. The majority reported an occurrence of one to two times, whereas 10% reported six or more times. The analysis suggested women aged 34–49 and 50–65 years, homo- and bisexual men, and singles more likely to have this experience. They were also more likely to have engaged in cybersex. No relationships were found with sexually transmitted infections or online sexual problems. The results suggest that using the Internet to find sex partners may be less hazardous for the general Internet users than pointed out by prior research about this behavior often focusing on specific sub groups of Internet users.
