    Closed vs open surgical exposure of palatally displaced canines: surgery time, postoperative complications, and patients' perceptions2018Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 40, nr 6, s. 626-635Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Closed and open surgical techniques are two different main approaches to surgical exposure of palatally displaced canines (PDCs). Because there is insufficient evidence to support one technique over the other, there is a need for randomized controlled trials.

    Objectives: To compare surgery time, complications and patients' perceptions between closed and open surgical techniques in PDCs.

    Trial design: The trial was a multicentre, randomized, controlled trial with two parallel groups randomly allocated in a 1:1 ratio.

    Material and methods: Study participants were 119 consecutive patients from 3 orthodontic centres, with PDCs planned for surgical exposure, randomly allocated according to a computer-generated randomization list, using concealed allocation. Full-thickness mucoperiosteal flap was raised, and bone covering the canine was removed in both interventions. In closed exposure, an attachment with a chain was bonded to the canine and the flap was sutured back with the chain penetrating the mucosa. In open exposure, a window of tissue around the tooth was removed and glass ionomer cement placed on the canine crown, to prevent gingival overgrowth during spontaneous eruption. Patient perceptions were assessed with two questionnaires, for the evening on the day of operation and 7 days post-surgery.

    Blinding: It was not possible to blind either patients or care providers to the interventions. The outcome assessors were blinded and were unaware of patients' intervention group.

    Results: Seventy-five girls and 44 boys, mean age 13.4 years (SD 1.46) participated in the study and got either of the interventions (closed exposure, n = 60; open exposure, n = 59). Surgery time did not differ significantly between the interventions. Complications though were more severe in bilateral cases and the patients experienced more pain and impairment in the open group.

    Conclusion: There were no statistically significant differences regarding surgery time between the groups. Postoperative complications were similar between the groups in unilateral PDCs, but more common in the open group in bilateral cases. More patients in the open group experienced pain and impairment compared to the closed group.

    Trial registration: Trial registration: ClinicalTrials.gov, ID: NCT02186548 and Researchweb.org, ID: 127201.

    Factors determining perceived orthodontic treatment need in adolescents of Swedish and immigrant background2009Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 31, nr 1, s. 95-102Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this study was to evaluate the association between self-perceived orthodontic treatment need and malocclusion in 12 to 13-year-old-adolescents of Swedish and immigrant background. The sample consisted of 379 students, stratified according to geographic background: both parents born in A/Sweden (n = 269), B/Eastern Europe (n = 56), and C/the Middle East (n = 54). Registrations were based on a questionnaire, a clinical examination, radiographs, and patient records. Treatment need was classified according to the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN). Logistic regression analysis was used for comparison of the results.

    Malocclusion frequency in Swedish and immigrant adolescents: influence of origin on orthodontic treatment need2007Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 29, nr 1, s. 79-87Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sweden has become increasingly multicultural, In the year 2000, almost 25 per cent of the child and adolescent population was of foreign origin. Such a major change in demographics may lead to altered orthodontic treatment need in the community, with implications for planning appropriate levels of orthodontic resources. The aim of this study was to compare the frequency of malocclusion and orthodontic treatment need in 12- and 13-year olds of Swedish and immigrant background. The subjects, n = 493, were stratified into four groups according to family origin: (A) subject and both parents born in Sweden, and subject or at least one parent born in (B) Eastern Europe, (C) Asia, or (D) other countries. Registrations were based on available radiographs, patient records, and a clinical examination. Normative treatment need was based on a number of variables. Treatment need was expressed according to the dental health component (DHC) and aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN).

    Group A exhibited the greatest space deficiencies and irregularities in the maxillary and mandibular anterior segments and also the greatest overjet. More primary molars had been extracted in groups B and C, with a positive correlation between early extraction of primary molars and retention of permanent successors. Self-assessed orthodontic treatment need, IOTN-AC, was highest in group A. For all four groups, the orthodontist's estimate of treatment need was significantly higher than the subjects' self-assessed need.

    This study confirms that, despite the change in demographics, variations in frequencies of malocclusion and treatment need among children of different cultural background are only minor and the overall orthodontic treatment need remains unchanged.

    Treatment of missing maxillary lateral incisors: a clinical and aesthetic evaluation2019Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 41, nr 3, s. 273-278Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The aim of this study was to evaluate whether implant therapy or orthodontic space closure was the best treatment option for patients with missing maxillary lateral incisors.

    Subjects and methods: The implant group (I group) consisted of 22 patients aged <26 years who had one or both maxillary lateral incisors substituted by a single implant-supported crown. The space-closure group (SC group) consisted of patients matched with I group patients based on diagnosis, gender, and number. Examinations were performed by one examiner and occurred at least 5 years after the prosthetic therapy or orthodontic treatment was finished. Clinical examination of the 44 patients involved assessing the aesthetics and gingival conditions of the implant-supported crown and the replacement canine, the occlusal morphology and the extraoral characteristics. Both the patient and examiner answered a question about their satisfaction with the aesthetic result.

    Results: Of the 12 variables analysed by the examiner, one variable was significantly improved in the I group and five variables were improved in the SC group. There were no significant differences between the treatment groups for the remaining six variables. Gingival colour and crown length were better in the SC group, and crown colour was better in the I group. There were no significant differences between the groups with regards to the patient's and examiner's overall aesthetic satisfaction of the maxillary anterior teeth or between the patient's and examiner's opinion.

    Conclusion: If both treatment alternatives are available, space closure is preferable.

    Early orthodontic treatment and interceptive treatment strategies2013Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 35, nr 2, s. 190-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Orthodontics as health care is sometimes at odds with modern marketing with its strong focus on aesthetics. In this commentary, I highlight how important it is that research of orthodontic treatment as a value for the entire community is performed and published.

    The effect of maceration on the dental arches and the transverse cranial dimensions: a study on the pig2002Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 24, nr 6, s. 667-676Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The dimensional change of the dental arches and the transverse cranial dimensions were studied in the pig to gain information on cranial post mortem changes and thus improve the possibilities of comparison between modern and skeletal samples. Dental arch dimensions were registered in 17 pigs within 30 minutes after they had been killed. The following day, the skulls were registered on lateral and axial radiographs. The animals were prepared, and storage and preparation included freezing and treatment in hot water. The water temperature did not exceed 65 degrees C. After this process, the skulls were again registered on lateral and axial radiographs. The skulls were then allowed to dry for 2 weeks and the direct measurements were repeated. The dimensions showed shrinkage of between 0 and 3.3 per cent. The mandible showed a greater change transversally in the posterior region than the cranium, which may have been due to its shape. The more deviant values for dimensional change were probably due to technical errors and the shrinkage may be expected to vary from 0.3 to 1.7 per cent, with greater values occurring in the posterior transverse parts of the mandible. A differential shrinkage in the maxilla could not be excluded and the values varied between 0.3 and 1.9 per cent. The results indicate that the crania in skeletal samples can be expected to be 0.3-1.7 per cent smaller than in vivo.

    Dummy-sucking behaviour in 3-year old Norwegian and Swedish children1996Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 18, nr 2, s. 205-209Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Forty 3-year-old dummy-sucking children (22 Swedes and 18 Norwegians) together with one of their parents, were shown a specially prepared videotape for 15 minutes The child had free access to its dummy while watching the video. The dummy-sucking time and sucking reactions to the different film sequences were registered. The presence or absence of a posterior crossbite was recorded as well as the upper and lower intercanine arch widths. Dummy-suckers in these populations have earlier been reported to have different prevalences of posterior crossbite. The prevalence of posterior crossbite was especially high for Swedish girls. The results showed that Norwegian boys used their dummies significantly less, and the Swedish girls had significantly narrower upper dental arches than the other children. Dummy-sucking reactions to frightening, cheerful or boring parts of the video were not significantly different among the children. All the children showed compassion for the film characters, and all the children used the dummy when going to sleep. The study lends support to the hypothesis that dummy-sucking influences arch widths and increases the likelihood for development of a posterior crossbite.

    Periodontal conditions around tipped and upright molars in adults: An intra-individual retrospective study.1992Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 14, nr 6, s. 449-455Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In 69 individuals from a randomized epidemiological material comprising 450 adults, an intra-individual comparison of the periodontal condition of 73 mesially tipped molars (30 degrees or more to a line perpendicular to the occlusal plane) and contralateral upright molars was made. The alveolar bone level mesially and distally of each tooth was registered in periapical radiographs. The occurrence of plaque, gingivitis and probeable pocket depths of 4 mm or more mesially and distally of each tooth was registered. No significant differences between tipped and upright molars could be found, regardless of the variable tested. The clinical implications of the findings are discussed from an orthodontic as well as a periodontal and prosthetic point of view.

    Long-term follow-up of orthodontically treated deep bite patients2006Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 28, nr 5, s. 503-512Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this study was to evaluate the long-term stability of corrected deep bite and mandibular anterior crowding in a sample of 62 subjects (30 patients and 32 controls). The patients began treatment at a mean age of 12.2 years (SD 1.56). The treatment consisted of non-extraction and fixed appliances in 23 subjects and functional appliances in seven. The treatment group was compared with the control group with normal molar occlusion, normal overjet and overbite, no crowding, and without an orthodontic treatment need. The registrations were made on four occasions: before treatment (T1), after treatment (T2), and at two long-term follow-ups (T3 and T4). Four registrations were also made in the control group. All measurements were undertaken on plaster models and lateral cephalograms. Treatment was found to have normalized the overbite and overjet and to have eliminated the space deficiency in the mandibular anterior region. At T4, there was a minor relapse in overbite in the treatment group (mean 0.8 mm). In the control group, the overbite underwent reverse development (bite opening by 0.7 mm) during the same period. The available mandibular incisor space, however, was -0.9 mm in the treatment group and -1.8 mm in the control group. The long-term stability of the treatment results was thus good.

    Autotransplantation of premolars to the maxillary incisor region: A long-term follow-up of 12-22 years2016Ingår i: European Journal of Orthodontics, ISSN 0141-5387, E-ISSN 1460-2210, Vol. 38, nr 5, s. 508-515Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To investigate the long-term outcome of treatment of missing maxillary incisor teeth by transplantation of premolars, with special reference to aesthetics and patient satisfaction.

    Subjects and Methods: Twenty subjects who had undergone transplantation of premolars to the maxillary incisor area were recalled for follow-up varying between 12 and 22 years post-surgery. Twelve subjects presented for examination, including radiography and three subjects participated only by answering questions. Three reference groups-general practitioners, orthodontists, and lay people-evaluated the aesthetic results from photographs. Patient satisfaction was evaluated by interviews and OHIP-14.

    Results: The mean age at transplantation was 12.3 years: 1 subject had been 20 years old and 11 were in the range of 9-14 years. Twelve to 22 years after autotransplantation, 5 subjects could not be reached: of the 15 who could be contacted, the survival rate was 15 out of 15. In the 12 subjects who presented for clinical examination, 11 out of the 12 transplants were assessed as successful. Nine transplants were restored with crowns and five had been recontoured with composite build-ups. In one patient, no restorative treatment had been undertaken. The subjects were satisfied with the aesthetic result.

    Conclusion: Autotransplantation of premolars is an appropriate method for treatment of missing maxillary anterior teeth. Subjects with a transplanted tooth to the maxillary anterior region perceive their oral health as good long term.
