- Objective: To estimate effective dose of cone beam CT (CBCT) of the facial skeleton with focus on measurement methods and scanning protocols. Methods: A systematic review, which adhered to the preferred reporting items for systematic reviews (PRISMA) Statement, of the literature up to April 2014 was conducted. Data sources included MEDLINE®, The Cochrane Library and Web of Science. A model was developed to underpin data extraction from 38 included studies. Results: Technical specifications of the CBCT units were insufficiently described. Heterogeneity in measurement methods and scanning protocols between studies made comparisons of effective doses of different CBCT units and scanning protocols difficult. Few studies related doses to image quality. Reported effective dose varied across studies, ranging between 9.7 and 197.0 mSv for field of views (FOVs) with height #5cm, between 3.9 and 674.0 mSv for FOVs of heights 5.1–10.0 cm and between 8.8 and 1073.0 mSv for FOVs .10 cm. There was an inconsistency regarding reported effective dose of studies of the same CBCT unit with the same FOV dimensions. Conclusion: The review reveals a need for studies on radiation dosages related to image quality. Reporting quality of future studies has to be improved to facilitate comparison of effective doses obtained from examinations with different CBCT units and scanning protocols. A model with minimum data set on important parameters based on this observation is proposed. Advances in knowledge: Data important when estimating effective dose were insufficiently reported in most studies. A model with minimum data based on this observation is proposed. Few studies related effective dose to image quality.

- Despite uneventful primary surgery, patients with cleft palate may experience velopharyngeal insufficiency (VPI) and hypernasal speech. Videoradiography of velopharynx is a commonly used method to visualize velopharyngeal function and a velopharyngeal flap is often used to counteract VPI. The aim of this study was to investigate whether the frontal projection on videoradiography plays a role in the decision-making about velopharyngeal flap surgery, or possibly the width and orientation of the flap. A secondary aim was to evaluate the effect of the flap in improving velopharyngeal function. Between 2007 and 2016, 75 patients had received a flap at our department. During the same period of time, 41 patients who had undergone videoradiography did not receive a flap. Medical records, particularly regarding speech assessments, videoradiography statements and operating records, were scrutinised to seek information about the factors leading up to the decision about whether or not to perform a flap. In only one instance, reduced lateral pharyngeal wall movement found on the frontal projection was clearly taken into account when deciding to refrain from performing a velopharyngeal flap. Only a slight agreement was found between pre-operative speech assessment and findings in videoradiography. Hypernasality was reduced by flap surgery in 97% of the patients. We conclude the frontal projection of the videoradiographic examination seems to have no crucial role in the decision-making on performing a velopharyngeal flap or not in patients with cleft palate. Even with reduced lateral pharyngeal wall movement, a velopharyngeal flap effectively reduces hypernasality and VPI.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundJuvenile idiopathic arthritis (JIA) often affects the temporomandibular joint (TMJ) caused by an abnormal immune system that includes overactive inflammatory processes. Salivary biomarkers may be a powerful tool that can help establishing diagnosis, prognosis and monitor disease progress.ObjectiveThe objective was to investigate biomarkers in parotid saliva and blood plasma in relation to temporomandibular joint (TMJ) magnetic resonance imaging (MRI) findings in patients with JIA and healthy individuals.MethodsForty-five children aged 6 to 16 years with JIA and 16 healthy age- and sex-matched controls were included. Unstimulated parotid saliva samples and venous blood were collected. Biochemical analyses were performed for the cytokine biomarkers. The participants underwent MR imaging of the TMJs, where changes in the inflammatory and the damage domains were assessed.ResultsIn the JIA patients, lower concentrations of IL-6R and gp130 were found in parotid saliva than in plasma. Higher concentrations of IL-6 were found in parotid saliva than in plasma. IL-6, IL-6R and gp130 in parotid saliva explained the presence of bone marrow oedema and effusion in the JIA patients.ConclusionsThis study suggests that the IL-6 family in parotid saliva is associated with TMJ bone marrow oedema and effusion in patients with JIA, suggesting that IL-6 has promising properties as a parotid saliva biomarker for TMJ inflammatory activity. image

- This study evaluated a pilot workshop for teaching communication skills to dental students. The methodology is based on an experiential learning approach, the use of realistic clinical scenarios, simulated patients, and an integrated teaching team of both educational researchers and dentists. Furthermore, the methodology was adapted for short workshops, which is thought to offer better possibilities for frequent and effective training of communication skills throughout the curriculum. The workshop was piloted with groups of six to ten students from the sixth and tenth semesters (n=94). Results show that the majority of students found the tasks meaningful and well aligned with how they perceived their future profession as dentists. Most students also thought that they learned from the task. An interesting finding is that students not only found it instructive to practice how to communicate in authentic situations, but that they generally found the workshop to be thought-provoking while at the same time providing structure and intellectual tools for the future. A possible explanation for this finding is the sharing of explicit criteria for high-quality communication.

- Objective: To analyze radiographic signs of temperomandibular joint (TMJ) osteoarthritis and clinical TMJ symptoms in patients 6 years and 32 years after treatment with a Herbst appliance. Materials and Methods: Fourteen patients were derived from a sample of 22 with Class II division 1 malocclusions consecutively treated with a banded Herbst appliance at the age of 12–14 years old (T1-T2). The subjects were reexamined after therapy at the ages of 20 years (T3) and 46 years (T4). The TMJs of the 14 patients were analyzed radiographically (conventional lateral tomography at T3 and cone-beam computed tomography at T4) and clinically/anamnestically at T3 and T4. Results: Six years after Herbst therapy, signs of osteoarthritis were seen in one patient. At the 32-year follow-up, two additional patients had developed signs of osteoarthritis. At the 6-year follow-up, TMJ clicking was present in two patients, though none of the patients reported TMJ pain. At the 32-year follow-up, six patients had TMJ clicking and one patient had TMJ pain. Conclusions: This longitudinal very-long-term follow-up study after Herbst therapy revealed only minor problems from the TMJ. The TMJ findings 6 years and 32 years after Herbst treatment corresponded to those in the general population. Thus, in the very long term, the Herbst appliance does not appear to be harmful to the TMJ.

- Purpose: To determine the incidence, prevalence, and progression of temporomandibular joint (TMJ) magnetic resonance (MR) imaging findings and symptoms during 15 years in adult asymptomatic and symptomatic volunteers (nonpatients).Materials and Methods: A regional committee for medical research ethics approved the study, and informed volunteer consent was obtained. Fifty-three volunteers were examined at study inception. For clinical assessment, a self-administered questionnaire was given, followed by an interview with each volunteer at study inception, at 1 year later, and at 15 years later. Bilateral TMJ MR imaging and clinical examination were performed at inception and at 15-year follow-up. The MR images were assessed for disk position, bone status, and joint fluid. All 53 volunteers participated at 1-year follow-up, and 50 of 53 volunteers participated at 15-year follow-up; of these 50 volunteers, 47 underwent MR imaging. The Fisher exact test was used to determine differences between groups, and the Wilcoxon signed-rank test was used to determine differences in prevalence of TMJ symptoms among the three examination times.Results: At study inception, TMJ disk displacement was observed in 31% of asymptomatic volunteers (nine of 29) compared with 89% of symptomatic volunteers (16 of 18, P < .001). Inceptive TMJ status was maintained after 15 years in 91% (43 of 47). Unilateral progression was observed in four volunteers (9%); one was symptomatic and three were asymptomatic. Progression involved development of new disk displacement (n = 1), development of new bone changes (n = 2), and aggravation from reducing to non-reducing disk displacement (n = 1). Prevalence of TMJ symptoms did not change significantly between examination times (P = .77). TMJ clicking was the most common clinical symptom.Conclusion: Volunteers with mild symptoms had a prevalence of disk displacement of the same magnitude as that reported in patients, although most volunteers, symptomatic as well as asymptomatic, maintained their TMJ status during 15 years.
