  Abstract Background Irisin is expressed in human periodontal ligament (hPDL), and its administration enhances growth, migration and matrix deposition in hPDL cells cultured in monolayers in vitro. Objectives To identify whether irisin affects the gene expression patterns directing the morphology, mechanical properties, extracellular matrix (ECM) formation, osteogenic activity and angiogenic potential in hPDL cell spheroids cultured in 3D. Materials and Methods Spheroids of primary human hPDL cells were generated in a rotational 3D culture system and treated with or without irisin. The gene expression patterns were evaluated by Affymetrix microarrays. The morphology of the spheroids was characterized using histological staining. Mechanical properties were quantified by nanoindentation. The osteogenic and angiogenic potential of spheroids were assessed through immunofluorescence staining for collagen type I, periostin fibronectin and von Willebrand factor (vWF), and mRNA expression of osteogenic markers. The secretion of multiple myokines was evaluated using Luminex immunoassays. Results Approximately 1000 genes were differentially expressed between control and irisin-treated groups by Affymetrix. Several genes related to ECM organization were differentially expressed, and multiple deubiquitinating enzymes were upregulated in the irisin-exposed samples analyzed. These represent cellular and molecular mechanisms indicative of a role for irisin in tissue remodeling. Irisin induced a rim-like structure on the outer region of the hPDL spheroids, ECM-related protein expression and the stiffness of the spheroids were enhanced by irisin. The expression of osteogenic and angiogenetic markers was increased by irisin. Conclusions Irisin altered the morphology in primary hPDL cell-derived spheroids, enhanced its ECM deposition, mechanical properties, differentiation and remodeling potential.

  Structured Abstract Authors - Franzen T.J., Monjo M., Rubert M., Vandevska-Radunovic V. Objectives - To investigate biological changes of alveolar bone occurring during orthodontic relapse. Materials and Methods - Maxillary first rat molars were moved mesially for ten days. After orthodontic tooth movement (OTM) appliances were removed, and the molars were allowed to relapse for one, three, five, seven, 14 or 21 days. Changes in 3D morphometric parameters of bone located mesial to the first molars were evaluated by micro-CT. Total RNA was isolated from the same bone site and real-time RT-PCR was used to measure the expression of bone formation and resorption markers. Results - One day after appliance removal, the molars relapsed to a mean 73% of the achieved OTM, and then steadily relapsed to 93% at 21 days. Tissue mineral density and percent bone volume increased over the experimental period. Inversely, there was a decrease in total porosity. Gene expression of OCN, Coll-I and ALP decreased during OTM, and as the molars relapsed showed an increasing tendency. Gene expression of RANKL and TRAP increased during OTM. Changes in mRNA expression of H+-ATPase were minor. By 21 days post-appliance removal the remodelling process in rats appeared to have returned to control levels. Conclusions –Bone tissue reactions on a molecular level are similar during OTM and orthodontic relapse. These findings validate the importance of immediate retention following active OTM. Key words: bone remodelling; micro-CT; orthodontic relapse; Real-time RT-PCR; tooth movement.

  AIM: To examine factors associated with patients' decision to decline surgery. MATERIAL/METHODS: Of 470 consecutive patients referred to the University of Oslo from 2007 to 2009, a sample of 160 subjects who had not undergone surgery was identified and contacted. 236 operated patients from the same period served as a comparison group. Morphology was assessed from cephalograms and photographs, and the individuals' opinions were recorded using questionnaires. RESULTS: Dentofacial morphology represented normative treatment need and was generally similar except for a higher rate of severe negative overjet in the operated group (p < 0.001). The most prevalent reasons for declining surgery were risks of side effects, the burden of care, and a general reluctance to undergo surgery. Many un-operated subjects were dissatisfied with their masticatory function and dentofacial appearance. CONCLUSION: Informed consent to orthognathic surgery represents a challenge both to the patient and the professional. The findings imply that patients' motives and fears should be explored during consultation and that the information provided should be adapted to the potential risks and benefits related to the actual treatment.

  Objectives:The purpose of this study was to investigate time-related dental tissue reactions to tooth replantation in mature and immature human premolars by histomorphometric and radiographic methods.Material and methods:Sixty premolars were extracted, immediately replanted (T0), and left without intervention for 1, 2, 3, 6, 12, and 24 weeks before re-extraction (T1). Periapical radiographs were taken at T0 and T1 in all groups except for the 24 week group. Paraffin-embedded teeth were sectioned buccolingually at 5 µm, stained with haematoxylin-eosin, and prepared for histological analysis. Root resorption, tertiary dentine, and root and crown length were recorded and compared on both radiographs and paraffin sections.Results:Initial degeneration of the odontoblast layer and disturbance of vasculature and normal architecture of the pulp were seen in both mature and immature teeth within the first 3 weeks. Revascularization and tertiary dentine formation was visible on histological sections in immature teeth at 6 weeks. After 24 weeks, most immature teeth had pulps partly or completely obliterated. Abundant tertiary dentine observed on histological slides was not easily seen on periapical radiographs. Likewise, surface root resorption found in both immature and mature teeth was not visible on the radiographs up to 6 weeks after replantation.Conclusion:Within the limits of this study it can be concluded that the dental pulp of immature teeth has the ability to regenerate and produce tertiary dentine after replantation. Root resorptions and tertiary dentine seen on histological sections are not visible on corresponding radiographs 6 and 12 weeks after replantation.

  Aims: To survey retention protocols and need for practical retention guidelines among orthodontists in Norway and to compare the results with similar studies in other countries. Methods: A questionnaire was mailed to all members of
the Norwegian Association of Orthodontists. It included questions about their background and their current retention protocol, as well as their perceived need for common retention guidelines. Results: The response rate was 77.7% (69.3% males and 30.7% females). The most common maxillary retainer was a combination of a fixed and removable retainer, followed by a clear thermoplastic retainer. In the mandible, a fixed retainer bonded to all anterior teeth was most common (66.4%). Retention in the maxilla lasted 2 to 3 years (34.7%) or 3 to 5 years (23.8%). In the mandible, 41.5% of the orthodontists left the retainer in place for >5 years. When retention lasted more than 3 years, 70% of the orthodontists left the responsibility for retainer checkups to the patients or the general practitioners. The main reason for choosing a certain retention protocol was clinical experience (57.4%). Only 3.5% of the orthodontists based their protocols on information from the literature. Half
of the orthodontists, significantly women, expressed a need for common retention guidelines. Conclusions: In Norway, bonded retainers alone were reported to be most commonly used in the mandible, while bonded retainers used in combination with a removable retainer appear to be the most commonly used appliances in the maxilla. This is similar to the most frequently used retainers in other countries, but there are disparities in duration and follow-up protocols. Most female orthodontists desire common retention guidelines.

  Relapse after orthodontic tooth movement (OTM) is an undesirable outcome that involves a number of factors. This study investigated the remodelling of the alveolar bone and related periodontal structures during orthodontic relapse in rat molars. The maxillary right first molars of 35 Wistar rats were moved mesially by a fixed orthodontic appliance for 10 days and the contralateral molars served as controls. The appliances were removed and six animals killed. The molars were allowed to relapse, and the remaining animals were sacrificed at 1, 3, 5, 7, 14, and 21 days. The jaws were sectioned and stained with haematoxylin and eosin and tartrate-resistant acid phosphatase (TRAP). One day after appliance removal, the molars relapsed to a mean 62.5 per cent of the achieved OTM and then steadily relapsed to 86.1 per cent at 21 days. The number of osteoclasts situated along the alveolar bone of the first molars was highest at the end of active treatment and significantly decreased during the relapse period. In the OTM group, osteoclasts were most numerous in the pressure side of the periodontal ligament (PDL). As the molars relapsed over time, the osteoclast distribution shifted, and after 7 days of relapse, TRAP-positive cells were registered in previous pressure and tension sides of the first molars. After 21 days, these cells were concentrated in the distal parts of the PDL of all three maxillary right molars. These results indicate that orthodontic relapse in the rat model occurs rapidly and remodelling of the alveolar bone and PDL plays a central role in the relapse processes of both actively moved and adjacent teeth.

  Aim(s): should be clearly stated. Beckwith - Wiedemann syndrome (BWS) is a rare paediatric overgrowth syndrome with distinct genetic and clinical features. Clinical findings are variable and include characteristic facial appearance, macroglossia, hemihypertrophy, anterior abdominal wall defects and gigantism. Macroglossia is present in most of the cases. The problems caused by the enlarged tongue comprise difficulties with feeding, distorted speech and increased drooling. The position of the teeth and lower jaw are often altered. Respiratory difficulties may occur due to tongue obstruction. The presence of hemi-hypertrophy can lead to asymmetric overgrowth of the head and face. Tongue reduction surgery is a treatment option. Based on systematically collected data, the development of the dentition and orofacial functions of 8 patients with BWS from childhood to adolescence is described. Methods: With sufficient detail of sampling, interventions and main outcome measures A Norwegian model for standardized long - term follow - up of the development of dentition, facial growth and orofacial functions was outlined by the TAKO - centre and the National Craniofacial Team in order to validate the quality of care of children and adolescents with Beckwith-Wiedemann syndrome (BWS). Examinations by a specialist in orthodontics, paediatric dentist, speech and language pathologist, otolaryngologist surgeon and plastic surgeon are performed at key ages in order to identify treatment needs and to provide coordinated care. This protocol includes follow - up of persons with BWS both with and without tongue reduction surgery. Results: should give the most important findings and always include both numbers and percentages All individuals in this study had a macroglossia and in two of them a tongue reduction was performed. A commom found was anterior open bite in the primary dentition. In the transition from mixed to permanent dentition a reduction of the anterior open bite was registered with dento - alveolar compensation. The orofacial functions such as speech, chewing and swallowing also improved from childhood to adolescence in most individuals. Conclusions: should highlight the most important finding(s) and be based on the observed results. This study may provide useful information for clinical guidelines and improve multiprofessional evidence based practice for Beckwith - Wiedemann syndrome.

  Aim: To examine the biological changes occurring in alveolar bone during orthodontic relapse. Materials and Method: Maxillary first rat molars were moved mesially for ten days, appliances were removed, and the molars allowed to relapse for 1, 3, 5, 7, 14 or 21 days. Maxillae of 35 rats were sectioned and stained with H&E and TRAP, whilst in 37 rats 3D morphometric parameters of bone sited mesial to the first molars were assessed by micro-CT, subsequently total RNA was isolated and real-time RT-PCR used to measure the expression of bone formation and resorption markers. Comparison among groups was assessed by t-tests or ANOVA, and correlations by Spearman’s rank correlation coefficient. Results: One day after appliance removal, the molars relapsed to 68.5% of the achieved OTM, and progressively relapsed to 90.6% at 21 days. Osteoclasts located along the alveolar bone of the first molars peaked at the end of active orthodontic tooth movement (OTM) and were most abundant in the pressure side of the PDL. Osteoclast numbers decreased significantly during relapse and their distribution shifted; after 7 days of relapse TRAP-positive cells were registered in previous pressure and tension sides of the first molars. After 21 days, these cells were concentrated in the distal sides of the PDL. In the bone mesial to the first molars tissue mineral density and percent bone volume increased whilst total porosity decreased over the experimental period. Gene expression of OCN, Coll-I and ALP decreased during OTM, and tended to increase as the molars relapsed. Gene expression of RANKL and TRAP increased during OTM. Changes in mRNA expression of H+-ATPase were minor. By 21 days the remodelling process appeared to have returned to control levels. Conclusion: The findings of this investigation indicate that orthodontic relapse in the rat model occurs rapidly and remodelling of the alveolar bone plays a central role in the relapse processes of both actively moved, and adjacent teeth.
