RESUMO
BACKGROUND: Qualitative sensory testing (QualST) is a simple, standardised, chairside method for evaluating somatosensory function; however, testing focuses on detection of cold, touch and pain with no recognition of perceptions of pleasantness and unpleasantness. OBJECTIVES: The study aimed to utilise the stimuli in QualST, with the addition of a soft brush, to investigate stimulus-evoked perceptions of pleasantness and unpleasantness on the facial skin and if any side-to-side differences. Additional aims were to determine the inter- and intra-rater reliability using the modified QualST protocol and in the side-to-side differences. METHODS: Thirty healthy adult female participants underwent three sessions of sensitivity testing as per the modified QualST protocol. Stimuli were applied bilaterally to the facial skin, and participants provided separate yes/no responses for presence of stimulus-evoked pleasantness, unpleasantness and/or differences between sides. RESULTS: The stimuli were able to evoke sensations of pleasantness and unpleasantness with little differences in responses between the Q-tip and goat hair brush for the perceptions. Side-to-side differences in evoked perceptions were observed and greatest, when evaluating for pinprick-evoked unpleasantness (range between sessions = 18-19 participants). Acceptable percentage (≥90%) and excellent Cohen's Kappa (≥0.762) inter- and intra-rater agreements were identified for one or more positive responses for each stimulus modality and the targeted perception. CONCLUSION: The modified QualST protocol provides a simple, reproducible method for the investigation of perceptions of pleasantness and unpleasantness, with readily accessible instrumentation to dental professionals and allowing for a more holistic approach in somatosensory testing.

The study aimed to summarize current knowledge regarding the use of orthopaedic functional appliances (OFA) in managing unilateral craniofacial microsomia (UCM). The eligibility criteria for the review were (1) assessing use of OFA as a stand-alone treatment and (2) using OFA in combination during or after MDO. The PICO (population, intervention, comparison and outcome) format formulated clinical questions with defined inclusion and exclusion criteria. No limitations concerning language and publication year were applied. Information sources: A literature search of Medline, Scopus, Embase, Cochrane Central Register of Controlled Trials, Web of Science databases without restrictions up to 30 September 2022. The risk of bias was assessed. According to Cochrane and PRISMA guidelines, two independent authors conducted data extraction. The level of evidence for included articles was evaluated based on the Oxford evidence-based medicine database. Due to the heterogeneity of studies and insufficient data for statistical pooling, meta-analysis was not feasible. Therefore, the results were synthesized narratively. A total of 437 articles were retrieved. Of these, nine met inclusion criteria: five assessing OFA and four assessing OFA during or after MDO. There is limited evidence to suggest that stand-alone and combination treatment with OFA is beneficial for treating mild-to-moderate UCM-related dentofacial deformities in short term. No studies assessed the burden of care. In the management of UCM, there is insufficient evidence supporting the efficacy of OFA as a stand-alone treatment or when combined with MDO. Additionally, there is a lack of evidence regarding treatment protocols and the effect on the condyles and the TMJ. The study was registered at Prospero database number CRD42020204969.
RESUMO
OBJECTIVE: To evaluate patients' experiences of shortened hospitalization in relation to bone grafting of unilateral alveolar clefts with mandibular symphyseal bone grafts. DESIGN: Prospective cohort questionnaire study. SETTING: Department of Oral and Maxillofacial Surgery, Aarhus University Hospital, Denmark. PATIENTS: Thirty-nine (male n = 26, female n = 13) patients with unilateral residual clefts after primary reconstruction, mean age 10.4 years. INTERVENTIONS: All patients underwent a standardized procedure with closure of the alveolar defect using mandibular symphyseal bone grafts. Patients were discharged within a day after surgery. Within 24 hours after discharge from surgery, patients and their parents filled in a 14-item psychometric questionnaire assessing the quality of their recovery. For all questions, a visual analogue scale (VAS) (0-10) was used. MAIN OUTCOME MEASURE: Patients' experience of shortened hospitalization in relation to secondary bone grafting of alveolar defects. Factors influencing the overall experience were measured using a VAS scale. RESULTS: A significant correlation between "Information from the hospital" and feeling worried and anxious was found (P = .04). Additionally, the ability to sleep correlated with pain (P = .003) and with nausea (P = .001). CONCLUSIONS: Although this study included a limited number of patients, the findings suggest that treatment of alveolar residual cleft with bone grafting from the mandibular symphyseal region in a day care surgery setting is characterized by very high patient satisfaction.

BACKGROUND: Osteonecrosis of the jaw (ONJ) is an adverse effect of antiresorptive treatment. This study estimated incidence proportions and incidence rates of ONJ in cancer patients with bone metastases from solid tumors treated for the prevention of skeletal-related events in routine clinical practice. METHODS: This cohort study in Denmark, Norway, and Sweden in 2011-2018 included 3 treatment cohorts: a denosumab inception cohort (DEIC), a zoledronic acid inception cohort (ZAIC), and a denosumab-switch cohort (DESC). The authors estimated 1- to 5-year incidence proportions and incidence rates of ONJ overall, by cancer site (breast, prostate, or other solid tumor), and by country. ONJ diagnoses were confirmed by adjudication. RESULTS: There were 1340 patients in the DEIC, 1352 in the ZAIC, and 408 in the DESC. The median ages of the 3 cohorts were 70, 69, and 70 years, respectively; the proportions of men were 72.6%, 53.8%, and 48.3%, respectively; and the median follow-up was 19.8, 12.9, and 13.3 months, respectively. The 5-year incidence proportions of ONJ were 5.7% (95% confidence interval [CI], 4.4%-7.3%) in the DEIC, 1.4% (95% CI, 0.8%-2.3%) in the ZAIC, and 6.6% (95% CI, 4.2%-10.0%) in the DESC. The corresponding ONJ incidence rates per 100 person-years were 3.0 (95% CI, 2.3-3.7), 1.0 (95% CI, 0.6-1.5), and 4.3 (95% CI, 2.8-6.3). Incidence proportions and incidence rates were highest in patients with prostate cancer and in Denmark. CONCLUSIONS: This study provides estimates of the risk of medically confirmed ONJ among patients initiating denosumab or zoledronic acid in routine clinical practice in 3 Scandinavian countries. The results varied by cancer site and by country. LAY SUMMARY: Denosumab and zoledronic acid reduce the risk of bone fractures, pain, and surgery in patients with advanced cancers involving bone. Osteonecrosis of the jaw (ONJ)-death of a jawbone-is a known side effect of treatment with denosumab or zoledronic acid. The authors examined almost 2900 denosumab- or zoledronic acid-treated patients with cancer in Denmark, Norway, and Sweden. Over the course of 5 years, ONJ developed in 5.7% of the patients whose initial treatment was denosumab, in 1.4% of the patients whose initial treatment was zoledronic acid, and in 6.6% of the patients who switched from zoledronic acid to denosumab.

PURPOSE: The aim of this study was to systematically review the literature to investigate the efficacy of physics forceps compared with conventional forceps for routine exodontia. METHODS: A systematic review was conducted using Embase, MEDLINE, PubMed, Scopus, Web of Science, Dentistry and Oral Sciences Source, Cochrane databases and Google Scholar. Primary outcomes investigated were buccal cortical plate fracture and gingival laceration and secondary outcomes included bleeding, delayed healing, ease of technique, pain, tooth fracture, operating time, and postoperative infection. RESULTS: Eight randomized controlled trials were included in the review. One study identified a significant difference in buccal cortical plate fracture (P = .001), and 3 studies reported a significant reduction in gingival laceration (all P ≤ .032) from using physics forceps, compared with conventional forceps. Secondary outcomes of bleeding (K = 2) and pain (K = 3), on day 1, were significantly reduced when using the physics forceps (P ≤ .001 and P ≤ .03, respectively). There were no significant differences or inconclusive results found for tooth fracture, operating time, ease of technique, postoperative infection, and delayed healing. CONCLUSIONS: The review identified that only a limited number of included studies were reported to provide a more atraumatic approach for routine exodontia in terms of buccal cortical plate fracture, gingival laceration, postoperative pain, and bleeding, when compared with conventional forceps. Most studies reported no significant differences. However, studies were associated with a high risk of bias and selective outcome reporting.

BACKGROUND: Tranexamic acid (TXA) reduces intraoperative blood loss and transfusion during paediatric craniosynostosis surgery. Additional reduction of postoperative blood loss may further reduce exposure to allogeneic blood products. We studied the effect of combined intra- and postoperative TXA treatment on postoperative blood loss in children. METHODS: Thirty children admitted for craniosynostosis surgery were randomised to combined intra- and postoperative TXA treatment or placebo. The primary endpoint was postoperative blood loss. Secondary endpoints included total blood loss, transfusion requirements, and clot stability evaluated by tissue plasminogen activator-stimulated clot lysis assay. RESULTS: TXA reduced postoperative blood loss by 18 ml kg-1 (95% confidence interval 8.9) and total blood loss from a mean of 52 ml kg-1 (standard deviation [SD]; 20) ml kg-1 to 28 (14) ml kg-1 (P<0.001). Intraoperative red blood cell (RBC) and fresh frozen plasma (FFP) transfusions were reduced in the treatment group from RBC 14.0 (5.2) ml kg-1 to 8.2 (5.1) ml kg-1 (P=0.01) and from FFP 13.0 (6.3) ml kg-1 to 7.8 (5.9) ml kg-1 (P=0.03). Postoperative RBC transfusion median was 5 (inter-quartile range [IQR] 0-6) ml kg-1 in the placebo group and 0 (0-5.7) ml kg-1 in the TXA group. Resistance to lysis was higher in the treatment group (P<0.001). CONCLUSIONS: Combined intra- and postoperative tranexamic acid treatment reduced postoperative and overall blood loss and transfusion requirements. Improved clot stability represents a possible mechanism for blood loss reduction.

OBJECTIVES: To evaluate the volumetric changes following lateral alveolar ridge augmentation using autogenous bone graft covered by either a platelet-rich fibrin membrane (test group) or an inorganic bovine bone substitute and a resorbable collagen barrier membrane (control group). MATERIAL AND METHODS: A total of 27 partially edentulous patients (test n = 14, control n = 13) with the indication for lateral bone block augmentation were included in this randomized, controlled clinical trial. Cone beam computed tomography (CBCT) examination was performed prior to grafting and 2 weeks and 6 months after grafting. The volumetric changes between the various examinations times were evaluated by planimetric measurements on two-dimensional CBCT images of the grafted regions. RESULTS: The mean bone volumetric loss in the test group was 14.7%, SD ±8.9%, while the mean bone volume loss in the control group was 17.8%, SD ±13.3%. This difference was not significant (p = 0.48). A total of ten patients were operated in the incisor and canine region with a mean bone volume loss of 23.41% SD, ±10.87%, while 17 patients were operated in the premolar region with a mean bone volume loss of 11.89% SD ±9.05%. This difference was significant (p = 0.01). CONCLUSION: The test and control group demonstrated no overall difference in volumetric bone changes of the augmented bone at the 6-month follow-up. The second major finding revealed a significantly larger amount of bone resorption in the incisor and canine region than in the premolar region of the maxilla, particularly in the control group.

OBJECTIVES: To assess the impact of cleft severity and timing of hard palate repair on palatal dimensions in unilateral cleft lip and palate (UCLP) children. SETTING AND SAMPLE POPULATION: Single-centre analysis within a multicenter RCT of primary surgery; 122 UCLP randomized to early hard palate closure (EHPC) at 12 months or delayed hard palate closure (DHPC) at 36 months; 28 frequency-matched controls. METHODS: Linear measurements of palatal height, width and length were performed on 116 digital models of UCLP subjects (8.21 years, SD = 0.53) and 28 models of non-cleft individuals (8.44 years SD = 0.72). Cleft dimensions at infancy (mean 1.8 months) were considered. In a pilot study, shell-to-shell distances between the 3D cleft palate objects and a reference mesh were calculated and differences between the groups assessed. Morphological differences were visualized using colour mapping. RESULTS: Compared to controls, UCLP subjects presented a higher palate at the level of the anterior scar (P = 0.002), but generally a lower palate in the middle region (P < 0.001). Comparing UCLP subgroups, the DHPC subjects showed a flatter palate posteriorly (P = 0.048) and the EHPC group exhibited more transversal constriction (P = 0.003 at M1 level). 3D analysis revealed a shallower palate in the DHPC group both in the middle (P = 0.002) and the posterior part (P = 0.008). Anterior cleft severity correlated negatively with palatal height (P = 0.01). CONCLUSIONS: Unilateral cleft lip and palate palates differ from controls in width and height. DHPC may represent an advantage for the transversal dimension, but a disadvantage for palatal height. Infant cleft dimensions partially explain differences in palatal height.

PURPOSE: Juvenile idiopathic arthritis (JIA) frequently affects the temporomandibular joints and may cause dentofacial deformity and dysfunction. The adverse effects of JIA on dentofacial growth, morphology, and function may be due to erosion of the existing mandibular condyle(s), the inhibitory effect of the arthritis on the growing mandible, or both. No algorithm exists for management of JIA-induced skeletal and dental abnormalities; treatment varies widely. MATERIALS AND METHODS: On the basis of the available literature and expert opinion obtained by a consensus conference held by the Temporomandibular Joint Juvenile Arthritis (TMJAW) group-a multidisciplinary and multinational clinical and research network dedicated to the diagnosis and management of temporomandibular joint arthritis caused by JIA-we present an algorithm to be used as a conceptual framework for management of dentofacial deformity resulting from JIA. RESULTS: An algorithm for management of dentofacial deformity resulting from JIA is presented and exemplified by 5 clinical cases. CONCLUSIONS: A standardized algorithm will improve clinical decision making and facilitate outcome research by allowing valid comparisons between published research studies. We emphasize the importance of multidisciplinary evaluation, management, and long-term follow-up.

Pediatric craniosynostosis (CS) surgery is frequently associated with extensive blood loss and transfusion requirements. The aim of the study was to evaluate the authors' institutional procedure with 2-surgeon approach and early transfusion strategy on blood loss and blood product transfusions in children undergoing craniofacial surgery. A retrospective analysis of medical records was performed of pediatric CS corrections during a 15-year period. Primary endpoint was blood loss and transfusion requirement during and the following 24âhours postoperatively. Linear regression analyses were performed of associations between intra and- postoperative blood loss and blood loss and weight. A total of 276 children (median 9 months) were included. Intraoperative blood loss was 22âmL/kg (14-33âmL/kg) and postoperatively 27âmL/kg (18-37âmL/kg), with no change during the study period. Intraoperative transfusions of red blood cell and plasma were 16âmL/kg (10-24âmL/kg) and postoperative 14âmL/kg (9-21âmL/kg). Postoperative red blood cell and plasma transfusions were 2âmL/kg (0-6âmL/kg) and of 0âmL/kg, respectively. Craniosynostosis type was related to blood loss (Pâ<â0.001). There was an association between intraoperative and postoperative blood loss (Pâ=â0.012) and intra- and postoperative blood loss and weight (Pâ=â0.002, Pâ=â<â0.001). Duration of surgery was 110âminutes (range 60-300âminutes).Pediatric CS surgery is associated with substantial intra- and postoperative blood loss and transfusion requirements, which did not change over a 15-year period. Blood loss was associated with type of CS. Intraoperative blood loss was correlated to postoperative blood loss and body weight.

OBJECTIVE: To present a 3-D standardized analysis of cleft dimensions. MATERIALS: Thirty-one plaster casts of unilateral cleft lip and palate (UCLP) infants were laser scanned. Landmarks and coordinate system were defined. Linear distances and surfaces were measured, and the ratio between cleft and palatal area was calculated (3-D infant cleft severity ratio [3D ICSR]). The digitally measured areas were compared with silicone membranes, adapted to the plaster casts, and analyzed by optic microscopy. MAIN OUTCOME MEASURES: Repeatability, reproducibility, and validity. RESULTS: Bland-Altman plots showed minor bias for anterior cleft width (0.16 mm), arch length (0.23 mm), and palatal surface (-9.18 mm2). The random error was maximum 0.78 mm for linear measurements and 12.1 mm2 for area measurements, reliability of 3D ICSR was 0.99 (intraclass correlation coefficient), differences between measurements on digital and plaster models were less than 2%. CONCLUSIONS: The method offers valid and reproducible 3-D assessment of cleft size and morphology. 3-D infant cleft severity ratio can be used as baseline value for surgical planning and may have a role in predicting dentofacial development.

PURPOSE: This study aimed to validate a predefined algorithm for osteonecrosis of the jaw (ONJ) among cancer patients in the Danish National Registry of Patients and to assess the nature of clinical information recorded in medical charts of ONJ patients. METHODS: We identified potential ONJ cases recorded in 2005-2010 among cancer patients at the hospital Departments of Oral and Maxillofacial Surgery (DOMS) in three Danish regions, using a set of codes from the International Classification of Diseases, 10th revision (ICD-10). We abstracted DOMS charts of the potential cases, had the ONJ status adjudicated by an expert ONJ adjudication committee (ONJAC), and computed positive predictive values. For patients with ONJAC-confirmed ONJ, we abstracted the charts for information on ONJ clinical course. Sensitivity of the algorithm was computed using a separate sample of 101 known ONJ cases accrued in 2005-2011. RESULTS: We identified 212 potential ONJ cases, of which 197 (93%) had charts available for abstraction. Eighty-three potential cases were confirmed by ONJAC, with a positive predictive value of 42% (95% confidence interval [CI] 35%-49%). DOMS charts of these 83 cases contained complete information on ONJ clinical course. Information about antiresorptive treatment was recorded for 84% of the patients. Among the 101 known ONJ cases, 74 had at least one prespecified ICD-10 code recorded in the Danish National Registry of Patients within ±90 days of the ONJ diagnosis (sensitivity 73%; 95%CI [64%-81%]). CONCLUSIONS: The predefined algorithm is not adequate for monitoring ONJ in pharmacovigilance studies. Additional case-finding approaches, coupled with adjudication, are necessary to estimate ONJ incidence accurately.

OBJECTIVES: To evaluate variation in treatment plans and pathological findings related to maxillary second and third molars based on panoramic (PAN) images and cone beam CT (CBCT) among Danish and Dutch oral and maxillofacial surgeons. STUDY DESIGN: This web-based "paper" clinic contained 10 cases of impacted maxillary third molars comprising clinical information, PAN, and CBCT. Treatment plan and pathological findings were established based on clinical information and PAN, thereafter, based on CBCT by 28 surgeons. Options for treatment plan for third molars were no treatment, or tooth removal. Options for treatment plan for second molars were no treatment, tooth removal, or endodontic and/or filling therapy. The surgeons assessed external root resorption, marginal bone loss, and follicular space. RESULTS: A change in treatment plan between PAN and CBCT was registered between 0% and 43% of the surgeons among the cases. The surgeons did not agree completely on the treatment plan in any of the cases. Variation was present among the surgeons evaluating pathological findings. In several cases, severity of root resorption was rated worse in CBCT than in PAN. CONCLUSIONS: Variation in treatment plan and pathological findings was observed among surgeons. No correlation between change in pathological findings and change in treatment plan was found.
RESUMO
OBJECTIVES: To evaluate whether information from CBCT changes the treatment plan for maxillary second and third molars and to examine clinical and radiographic parameters with an impact on treatment decision. METHODS: This prospective study included 260 maxillary third molars with superimposition onto the second molar in panoramic images (170 patients; mean age 28 years, range 16-63). An initial treatment plan was based on clinical findings and panoramic images. After CBCT, a final treatment plan was decided. Treatment was undertaken based on the final treatment plan. Through logistic regression analyses, impact of clinical and radiographic parameters on change in treatment plan, removal of the third molar vs no treatment, and removal of the second vs third molar were evaluated. RESULTS: The treatment plan changed in 82 cases (32%). Sixteen cases (6%) changed from removal of the third molar to removal of the second molar. Regression analyses showed that severe resorption in the second molar was significantly related to a change in treatment plan. Removal of a third molar was decided in 180 cases and regression analyses identified that mesioangulation of the third molar, marginal bone loss, superficial resorption, and age were significantly related to removal of the third molar vs no treatment. Thirty second molars were removed, and regression analyses showed that severe resorption was significantly related to removal of the second molar instead of the third molar. CONCLUSIONS: Parameters such as resorption evaluated in CBCT can modify the treatment decision, resulting in removal of the second and/or the third molar.

Background: The glandular odontogenic cyst is now a well-known entity comprising < 0.5% of all odontogenic cysts with a recent review tabulating about 200 cases in the English literature. Glandular odontogenic cyst shows epithelial features that simulate salivary gland or glandular differentiation. The importance of glandular odontogenic cyst relates to the fact that it has a high recurrence rate and shares overlapping histologic features with central mucoepidermoid carcinoma. The purpose of this paper is to describe the clinical, radiological, and histopathological features of a case of glandular odontogenic cyst with the course of treatment and 9-years follow-up, followed by a review of the literature. Methods: A 63-year-old male was referred for further investigation of a mandibular radiolucency observed by his general dental practitioner. The main complaint was a murmuring sensation in the lower jaw right side. Radiological examination revealed a well-defined, unilocular, radiolucent lesion, involving the right mandible with 17 and 68 mm in mediolaterally and anteroposterior dimension, respectively. Results: A total enucleation of the cystic lesion and surgical extraction of tooth #46, #47 and #48, was performed under local anaesthesia. Histopathologic examination revealed a glandular odontogenic cyst. Conclusions: Glandular odontogenic cyst shows no pathognomonic clinico-radiographic characteristics, and therefore in many cases it resembles a wide spectrum of lesions. Diagnosis can be extremely difficult due to histopathological similarities with dentigerous cyst, lateral periodontal cyst and central mucoepidermoid carcinoma. Therefore a careful histopathological examination and a long-term follow-up (preferably seven years) are required to rule out recurrences.
RESUMO
Objectives: Dentofacial deformity following juvenile idiopathic arthritis with temporomandibular joint involvement is associated with functional, aesthetic, and psychosocial impairment. Surgical treatment may involve combinations of orthognathic surgery. The aims of this retrospective study were to assess orofacial symptoms, functional and aesthetic status, and stability after orthognathic surgery. Material and Methods: Nineteen patients with juvenile idiopathic arthritis of the temporomandibular joint (TMJ) and dentofacial deformities were included. All patients were treated with combinations of bilateral sagittal split osteotomy, Le Fort I and/or genioplasty, between September 10, 2007 and October 17, 2017. Analysis of patient symptoms and clinical registrations, and frontal/lateral cephalograms was performed pre- and postoperative and long-term (mean: 3.8 and 2.6 years, respectively). Results: Patients experienced no changes in orofacial symptoms or TMJ function, and stable normalisation of horizontal and vertical incisal relations at long-term (horizontal overbite; vertical overbite: P < 0.05). Mandibular lengthening was achieved postoperatively (from mean 79.7 to 87.2 mm; P = 0.004) and was stable. Sella-nasion to A point (SNA) and sella-nasion to B point (SNB) angles increased postoperatively (SNA, mean 79.9° to 82.8°; P = 0.022 and SNB, mean 73.9° to 77.8°; P = 0.003), however, largely reverted to preoperative status at long-term. Conclusions: Orthognathic surgery normalized incisal relations while providing stable mandibular lengthening without long-term deterioration of temporomandibular joint function or orofacial symptoms. No long-term effect on jaw advancements was observed.
RESUMO
OBJECTIVE: To estimate the cumulative incidences of orofacial conditions related to temporomandibular joint (TMJ) juvenile idiopathic arthritis (JIA) between diagnosis in childhood to transition into adult care, and to identify features in JIA associated with TMJ involvement. METHODS: A population-based cohort analysis was conducted of patients with JIA involving longitudinal data on orofacial health from 2000 to 2018. Regardless of TMJ status, the patients were referred to the Regional Specialist Craniofacial Clinic of Western Denmark for routine orofacial examinations. Data collection included information about disease-specific background characteristics, TMJ involvement, JIA-induced dentofacial deformity, and orofacial symptoms and dysfunction. RESULTS: A total of 613 patients were followed up with a mean clinical TMJ observation time of 4.0 years. From JIA onset to transition into adult care, the cumulative incidence of patients with JIA involvement of the TMJ was 30.1%. Furthermore, 20.6% of the cohort had developed arthritis-induced dentofacial deformity. A substantial proportion of the cohort experienced several events with orofacial symptoms (23.5%) and dentofacial dysfunction (52%). Young age at diagnosis (<9 years), female gender, and antinuclear antibody positivity were significantly associated with TMJ involvement. CONCLUSION: Orofacial signs and symptoms were frequent findings in children and adolescents with JIA. TMJ involvement was seen in 30.1% of the cohort; and 20.6% of the total cohort developed JIA-related dentofacial deformity before transition into adult care. This is the first population-based study in the era of available biologic treatments to document these frequent orofacial complications in children with JIA.

Involvement of the temporomandibular joint (TMJ) is common in juvenile idiopathic arthritis (JIA). TMJ arthritis can lead to orofacial symptoms, orofacial dysfunction, and dentofacial deformity with negative impact on quality of life. Management involves interdisciplinary collaboration. No current recommendations exist to guide clinical management. We undertook this study to develop consensus-based interdisciplinary recommendations for management of orofacial manifestations of JIA, and to create a future research agenda related to management of TMJ arthritis in children with JIA. Recommendations were developed using online surveying of relevant stakeholders, systematic literature review, evidence-informed generation of recommendations during 2 consensus meetings, and Delphi study iterations involving external experts. The process included disciplines involved in the care of orofacial manifestations of JIA: pediatric rheumatology, radiology, orthodontics, oral and maxillofacial surgery, orofacial pain specialists, and pediatric dentistry. Recommendations were accepted if agreement was >80% during a final Delphi study. Three overarching management principles and 12 recommendations for interdisciplinary management of orofacial manifestations of JIA were outlined. The 12 recommendations pertained to diagnosis (n = 4), treatment of TMJ arthritis (active TMJ inflammation) (n = 2), treatment of TMJ dysfunction and symptoms (n = 3), treatment of arthritis-related dentofacial deformity (n = 2), and other aspects related to JIA (n = 1). Additionally, a future interdisciplinary research agenda was developed. These are the first interdisciplinary recommendations to guide clinical management of TMJ JIA. The 3 overarching principles and 12 recommendations fill an important gap in current clinical practice. They emphasize the importance of an interdisciplinary approach to diagnosis and management of orofacial manifestations of JIA.

The aim of this case report is to describe the surgical technique and outcome using internal intraoral distraction devices in LeFort II distraction with zygomatic repositioning (LF2ZR). In Apert syndrome the midface is characterized by a complex hypoplasia, with the central part being more affected than the lateral orbito-zygomatic complex. In LF2ZR, the zygomas are repositioned and internally fixated, and the central midface is further advanced through a LeFort II distraction. In previous publications, the distraction has been performed using external halo-based devices. It seems that the LF2ZR procedure can be planned and performed with adequate accuracy using virtual surgical planning tools. Knowledge about the possibility of using internal intraoral distraction devices in LF2ZR is important, as the inconspicuous placement of intraoral devices can be advantageous for some patients.

PURPOSE: To compare the survival and clinical performance of implants placed in sites previously augmented with autogenous bone grafts covered by either a platelet-rich fibrin (PRF) membrane (PRF group) or a standard procedure (gold standard) involving coverage of the autogenous bone graft with deproteinised bovine bone mineral and a resorbable collagen membrane (control group). METHODS: A total of 27 partially edentulous patients (test n = 14, control n = 13) with indication for staged lateral bone block augmentation and dental implant placement were included. Twenty-four months after crown placement (range: 14-32 months), patients were recalled for a final clinical and radiographic follow-up. Outcome measures were implant survival, implant crown survival, clinical parameters of the implant, peri-implant marginal bone level, marginal bone level of adjacent tooth surfaces, biological and technical complications and patient-related outcome measures. RESULTS: Two implants were lost in the control group (85% survival rate); none were lost in the PRF group (100% survival rate). None of the 26 initially placed implant crowns were lost, but one implant and therefore one implant crown were lost after 20 months. Consequently, the definitive implant crown survival was 92% (95% confidence interval (CI): 73-110%) in the control group and 100% in the PRF group. No statistical difference in implant survival rate (p = 0.13) or implant crown survival was seen between the groups (p = 0.28). The mean marginal bone level at the follow-up was 0.26 mm (95% CI: 0.01-0.50 mm) in the PRF group and 0.68 mm (95% CI: 0.41-0.96 mm) in the control group. The difference between the groups was - 0.43 mm (95% CI: - 0.80 to - 0.05 mm, p = 0.03), which was statistically significant (p = 0.03). Both groups demonstrated similar healthy peri-implant soft tissue values at the final follow-up. CONCLUSION: Although the current study is based on a small sample of participants, the findings suggest that the methodology of the PRF and the control group approach can both be used for bone augmentation with a similar outcome. A significant, but clinically irrelevant, higher peri-implant marginal bone level was registered in the PRF group than in the control group. Patients in both groups were highly satisfied with the treatment. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04350749 . Registered 17 April 2020. Retrospectively registered.
