Patients exposed to a combination of antiresorptive medication and radiotherapy of the head and neck area developing necrosis of the jaw in the course of treatment are extremely rare. Therefore, the aim of this study was to identify the outcome and complications in this highly vulnerable patient cohort. Seventeen patients who received both antiresorptive treatment and radiotherapy (medication-related osteonecrosis of the jaw/osteoradionecrosis = the [MRONJ/ORN] group) in the head and neck area were enrolled in this study. Included patients were treated in our department between 2005 and 2022. Four hundred twenty-four patients with MRONJ (the MRONJ group) and 138 patients with ORN of the jaw were enrolled as two control groups (the ORN group). Demographic data, lesion localization, date of primary diagnosis, clinical symptoms, type of therapy (surgical or non-surgical), details on antiresorptive treatment, outcome, and complications were recorded. Pathological fractures, continuity resection, and recurrence appear more often in patients who receive a combination of antiresorptive treatment and radiotherapy in the head and neck area compared with patients undergoing only one of these treatments. There was a statistically significant difference ( < .001) between the MRONJ/ORN group and the MRONJ group and the MRONJ/ORN group and the ORN group considering recurrence, fracture, and continuity resection. Patients with ORN combined with MRONJ have a 4-times higher risk for developing recurrence compared with patients with MRONJ and a 1.5-times higher risk for recurrence compared with patients with ORN. Jaw fracture and continuity resection appear more often in patients with MRONJ/ORN. Patients under antiresorptive therapy in combination with radiation therapy in the head and neck area have a higher risk for developing complications in case of osteonecrosis of the jaw. Therefore, a strict follow-up care schedule is highly recommended.

To assess the effect of a blooming artifact reduction (BAR) filter on cone beam computed tomography images (CBCT) in the dimensional analysis of dental implants. Six types of implants ( = 5 for each type) composed of titanium (3 types), titanium-zirconia alloy, zirconium oxide, and titanium-aluminum-vanadium alloy, and made with 2 manufacturing processes (milled and printed) were individually installed in a bovine rib block according to the manufacturer's protocol. CBCT images were acquired with i-CAT and Carestream 9600 scanners, randomized, and analyzed without and with the e-Vol DX BAR filter (60 images for each scanner). Implant length, diameter, and thread-to-thread distance were measured by two radiologists, with a stereomicroscopic image of each implant as the reference standard for calculation of distortion in measurements. Repeated measures ANOVA with Bonferroni corrections and intraclass correlation coefficients (ICC) were applied (α = 0.05). The BAR filter significantly reduced distortion in various parameters for specific implants, aligning closely with stereomicroscopic measurements. Titanium and printed implants showed reduced dimensional distortion regardless of BAR filter use. Carestream measurements presented smaller dimensional differences than i-CAT for most implants and parameters, especially without BAR ( < .05). Interexaminer reliability was good to excellent, with ICC ranging from 0.80 to 0.95. The BAR filter can enhance implant dimensional analysis, although variations based on implant material and manufacturing process were observed.

This study clarified possible delays and deficiencies in severe odontogenic infection (OI) treatment in patients with mental disorders. Data of hospitalized patients with severe OI were evaluated retrospectively. The outcome variable was preceding health care visits prior to hospitalization. The primary predictor was patient's mental disorder. Explanatory variables were age, sex, smoking, heavy alcohol use, immunocompromised disease or medication, and time span from beginning of symptoms to hospitalization. Also, factors leading to intensive care unit (ICU) care were evaluated. Preceding visits prior to hospitalization were found in 61 (35.5%) out of 172 patients with OI. In total, 27 patients (15.7%) had a current mental disorder, more commonly in women (26.0%) than in men (8.1%) ( = .001). Patients with mental disorders had preceding health care visits related to the current infection notably more often than patients without recent psychiatric history (51.9% vs. 32.4%), = .053. Patient-related treatment delay remained nonsignificant. Heavy alcohol use ( = .010) and smoking ( = .025) predicted ICU treatment, but no association with patient's mental disorder was found. A patient's mental disorder can complicate diagnosis of OI. Effective and timely treatment requires the professional's ability to simultaneously identify the patient's mental health challenges and progressing OI.

To evaluate the performance of convolutional neural networks (CNNs) for the automated detection and classification of mandibular fractures on multislice spiral computed tomography (MSCT). MSCT data from 361 patients with mandibular fractures were retrospectively collected. Two experienced maxillofacial surgeons annotated the images as ground truth. Fractures were detected utilizing the following models: YOLOv3, YOLOv4, Faster R-CNN, CenterNet, and YOLOv5-TRS. Fracture sites were classified by the following models: AlexNet, GoogLeNet, ResNet50, original DenseNet-121, and modified DenseNet-121. The performance was evaluated for accuracy, sensitivity, specificity, and area under the curve (AUC). AUC values were compared using the -test and values <.05 were considered to be statistically significant. Of all of the detection models, YOLOv5-TRS obtained the greatest mean accuracy (96.68%). Among all of the fracture subregions, body fractures were the most reliably detected (with accuracies of 88.59%-99.01%). For classification models, the AUCs for body fractures were higher than those of condyle and angle fractures, and they were all above 0.75, with the highest AUC at 0.903. Modified DenseNet-121 had the best overall classification performance with a mean AUC of 0.814. The modified CNN-based models demonstrated high reliability for the diagnosis of mandibular fractures on MSCT.

The aim of this study was to investigate the characteristics of illicit cocaine and opioid drug-related facial trauma and determine whether the presence of cocaine or opioid drug use in facial trauma patients influenced the cause of injury, morbidity, or management. A retrospective observational cohort study was performed using records from a state-wide database of all patients who presented to a Victorian hospital with a facial fracture between 2004 and 2014. Data collected included demographics, concomitant opioid and cocaine use, mechanism of injury, facial injuries, and management. Statistical analysis was done using chi-square test, Student's tests, binary logistic regression analysis, and multivariable linear regression analysis. Results were considered statistically significant if < .05. A total of 54,613 patient presentations for facial trauma were analyzed with 363 patients in the cocaine and opioid-related group, and 54,250 patients in the nondrug-related group. Patients with illicit drug use were more likely to have facial fractures caused by interpersonal violence when compared with nondrug users (47.9% vs 23.5%, OR = 2.23, < .001). Opioid and cocaine users had 0.3 more total fractures per presentation, which included more midface and skull fractures, and more facial lacerations ( < .001). There was no statistically significant difference in the need for surgical management between the two groups. Opioid and cocaine affected patients also on average had a longer hospital stay of 3.4 days and required 0.9 more allied health inputs during their admission when compared with nondrug users ( < .05). This effect was similarly reflected when controlling for confounding variables ( < .001). Concomitant cocaine or opioid use in facial trauma patients leads to more violence-related injuries with higher morbidity and healthcare costs.

U2AF homology motif kinase 1 (UHMK1) is a newly discovered molecule that may have multiple functions. Recent studies have revealed that UHMK1 had aberrant expression in many tumors and was associated with tumor progression. However, UHMK1 was rarely reported in oral squamous cell carcinoma (OSCC). In this study, Western blot, quantitative real-time polymerase chain reaction (PCR), and immunohistochemistry were used to detect the expression of UHMK1 in OSCC and peritumoral non-neoplastic tissues. Then, its relationship with clinicopathologic parameters was analyzed. The Kaplan–Meier method and Cox regression model were used to analyze the effects of UHMK1 expression on the prognosis and survival of OSCC patients. Our results showed that UHMK1 had higher expression in OSCC tissues compared with in peritumoral non-neoplastic tissues, and its high expression was associated with high TNM stage and lymph node metastasis. High UHMK1 expression was related to short overall and disease-free survival times. Moreover, UHMK1 expression was identified as an independent prognostic factor that influences overall and disease-free survival of OSCC patients. High expression of UHMK1 is associated with the poor prognosis of patients, and it can be used as a potential prognostic molecule for OSCC.

To report the first examples of ectopic salivary glands of TMJ ligaments & capsules. Nine subjects with chronic TMJ disorders were found incidentally to have ectopic salivary glands (choristomas) within or near damaged TMJ ligaments and capsules. Clinicopathologic characteristics of 12 TMJs are summarized. The 9 subjects were ages 22-64 years (average = 43.0); 6 were female. Microscopic examination revealed major, almost complete ligament replacement by dense, avascular fibrous scar tissue in all but 1 sample. Chronic inflammatory cells were present in the stroma of 3 samples. A total of 33 lobular, independent salivary structures of variable sizes where embedded in or near ligaments and/or capsules. Half were multiple in the same joint; 13 were bilaterally located in the joints of a single subject, with 8 small glandular lobules in one TMJ. All glands consisted of histologically normal serous acini except 1 which showed a focal lobule of mucus acini and another comprised only of mucus acini. Serial sections showed no connection to parotid glands. Some choristomas showed the aging phenomena of fatty infiltrates (n = 7) and oncocytosis (n = 7). Additionally, 3 of the 12 TMJ samples contained preauricular lymph nodes, with 3 nodes in 1 joint and bilateral involvement in 1 subject. Of the 5 identified nodes, all but one was hyperplastic, with nonspecific inflammatory histiocytosis. We report, for the first time, independent salivary gland choristomas (n = 33) within the soft tissues of the TMJ (n = 12), with one joint containing 8 such choristomas. All consisted of normal serous tissue except one, a mucus gland. Additionally, a fourth of TMJ surgical samples contained hyperplastic preauricular lymph nodes.

To assess the clinical scenarios in which nerve blocks are employed in the context of burning mouth syndrome (BMS). This scoping review followed the PRISMA-ScR. A protocol was generated on Open Science Framework. Electronic searches were performed in the following databases: PubMed, Scopus, EMBASE, Web of Science, LILACS, and Cochrane, in addition to the grey literature and citations from Grémeau-Richard et al. (2010). Nerve blocks were used for treatment purposes in all cases. The mandibular nerve and the stellate ganglion were both blocked in 50% studies, while the maxillary nerve and lingual nerve were blocked in 25% study each. The anesthetics used were lidocaine (50%) and bupivacaine (50%). Relief was generally reported after immediate block, and at a mean follow-up of 4.5 weeks, there was considerable improvement compared to the initial conditions when the mandibular and/or maxillary nerve were targeted. The use of nerve blocks has been employed in the treatment of patients with refractory BMS. Clinical studies with standardized methodology are necessary to validate and understand the potential role of mandibular and maxillary nerve block in this setting.

To evaluate if regenerative materials with/without scaffold deployed in dental socket preservation led to reduced radiographic height and width bone resorption. English-written human studies from January 2010 to December 2023 were selected from PubMed, EMBASE, MEDLINE, Cochrane CENTRAL, Google Scholar and manually searched journals. Six meta-analyses were conducted, addressing treatments with all blood-derived growth factor preparations as well as L-platelet-rich fibrin (L-PRF) separately, and recombinant human BMP-2 (rhBMP-2). An unpaired t-test on L-PRF and rhBMP-2 determined the clinically best preservation treatment. Cochrane risk of bias in all studies was analyzed. Twenty-nine articles (1068 participants) were included. Meta-analyses on blood-derived preparations demonstrated nonsignificant alveolar width, but significant ( = .001) height preservation. L-PRF vs. natural healing demonstrated nonsignificant changes in both dimensions. RhBMP-2 caused highly significant reduced horizontal ( = .01) and vertical ( < .0008) bone resorptions. When comparing mean resorption rates, significant benefits of rhBMP-2 over L-PRF were observed for width but not height preservation ( < .0001 and = .057, respectively). Six studies recorded low, 8 moderate, and 15 high net risks. Regenerative materials appear beneficial for radiographic bone width and height preservation after tooth extraction. Although rhBMP-2 performed better in alveolar width preservation, L-PRF can be an autologous and cost-effective alternative.
