Evaluation of a Structured Light Scanner for 3D Facial Imaging: A Comparative Study with Direct Anthropometry.

This study evaluates the accuracy and repeatability of craniofacial measurements with a 3D light scanner, specifically the EINSTAR scanner, in comparison to traditional caliper measurements for facial anthropometry. Eleven volunteers were assessed by two examiners, one experienced and one inexperienced, who performed direct caliper measurements and indirect measurements using the scanner. Results indicated minimal differences between caliper and scanner results, with overall high accuracy and reliability demonstrated by correlation coefficients. Despite the slightly longer scanning time, the benefits of 3D imaging, including detailed surface mapping and virtual modeling, justify its integration into clinical practice, particularly in maxillofacial surgery and craniofacial assessment. Craniofacial measurements obtained with the EINSTAR scanner showed excellent reliability and accuracy, which qualifies this method for clinical and scientific use.

Solitary ameloblastic fibroma with impacted teeth: A case report.

This case report aimed to describe a rare benign mandibular tumour and assess the outcomes of the most recent reviews, between January 2017 and August 2023. Presenting a detailed clinical case, this study advances our understanding of the diagnostic and therapeutic aspects, ultimately improving the management of similar cases in clinical practice. Orthopantomogram (OPG) revealed a well-defined unilocular radiolucency extending from the midline of the ramus and teeth 47 and 48 were submerged at the base of the mandible. In the presented case, a PLANMECA ROMEXIS PROMAX® three-dimensional (3D) maximum (MAX) cone-beam computed tomography (CBCT) device was used for the 3D examination. An intraoral approach was preferred and the tumour was removed in toto by creating a bone window using a W&H® Dentalwerk Bürmoos GmbH Piezomed piezoelectric device, and the bone plates were fixed with 4 MEDARTIS® microplates, with a primary flap closure. A PANORAMIC 1000, 3DHISTECH Ltd® device was employed for the histological investigation. Odontogenic tumours are rare and typically asymptomatic, often discovered incidentally during routine radiographic examinations. Most of these benign lesions heal well after complete excision and require long-term follow-up. Once diagnosed, ameloblastic fibroma (AF) should be treated immediately to avoid malignant transformation.

Association between Hyperglycemia and Medication-Related Osteonecrosis of the Jaw (MRONJ).

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a type of jawbone necrosis caused by the use of drugs for some types of cancer and osteoporosis. The current study aimed to evaluate the associations between hyperglycemia and the development of medication-related osteonecrosis of the jaw. METHODS: Our research group investigated data collected between 1 January 2019 and 31 December 2020. A total of 260 patients were selected from the Inpatient Care Unit, Department of Oromaxillofacial Surgery and Stomatology, Semmelweis University. Fasting glucose data were used and included in the study. RESULTS: Approximately 40% of the necrosis group and 21% of the control group presented with hyperglycemia. There was a significant association between hyperglycemia and MRONJ (p < 0.05, p = 0.003). Vascular anomaly and immune dysfunction caused by hyperglycemia can lead to necrosis after tooth extraction. Necrosis is more common in the mandible (75.0%) and in the case of parenteral antiresorptive treatment (intravenous Zoledronate and subcutaneous Denosumab). Hyperglycemia is a more relevant risk factor than bad oral habits (26.7%). CONCLUSIONS: Ischemia is a complication of abnormal glucose levels, a possible risk factor for necrosis development. Hence, uncontrolled or poorly regulated plasma glucose levels can significantly increase the risk of jawbone necrosis after invasive dental or oral surgical interventions.

Preoperative HbA1c and Blood Glucose Measurements in Diabetes Mellitus before Oral Surgery and Implantology Treatments.

Diabetes mellitus has become a worldwide epidemic and is frequently accompanied by a number of complications proportional to the duration of hyperglycemia. The aim of this narrative review is to assess the most up-to-date guidelines on DM provided by both diabetes and dental associations. Furthermore, to gather evidence on the uni/bidirectional relationships of elevated HbA1c levels on dental surgery, implantology, bone augmentation, and periodontology and to demonstrate the importance of measuring HbA1c levels before invasive dental treatments. HbA1c and blood glucose measurements are a minimally invasive method for preventing complications in diabetes mellitus. The authors conducted a literature review to determine which oral conditions are affected by diabetes mellitus. MEDLINE served as a source with the use of a specific search key. Regarding oral complications of diabetes, prevention is the most vital factor. With this publication, we hope to assist physicians and dentists to make prompt diagnoses and to help in recognizing various oral manifestations of diabetes and follow the existing guidelines.

Point-of-care HbA1c Measurements in Oral Cancer and Control Patients in Hungary.

BACKGROUND/AIM: This study aimed to investigate the link between preoperative glycated hemoglobin (HbA1c) levels and oral cancer patients and diabetes mellitus (DM). We aimed to highlight the importance of point-of-care HbA1c measurements in oral cancer patients. PATIENTS AND METHODS: A total of 214 patients were admitted to the Department of Inpatient Care at Semmelweis University's Department of Oromaxillofacial Surgery and Stomatology between 1 September 2020 and 21 May 2021; individuals, who had undergone maxillofacial surgery under general anesthesia, were included in the study. RESULTS: There was a significant difference between the oral cancer group and the control group in terms of smoking (p=0.009) and alcohol intake (p=0.003). There was no statistically significant difference regarding sex (p=0.132) and DM (p=0.147) between the two groups. The tumor group had an 8.52% greater prevalence of DM, which was not significant. In the oral cancer group, twenty individuals (17.69%) had a higher HbA1c level than the upper level of the optimal metabolic value (6.9%). Nine participants (8.91%) in the control group had an HbA1c value greater than 6.9%, which means that their metabolic level was poor. The oral cancer group did not have higher blood glucose levels than those of the control group. CONCLUSION: No direct connection between high blood glucose levels and oral cancer was found. However, point-of-care HbA1c measurement can be a diagnostic tool to detect DM in the dental office.

Maslach and Jackson. Results: In the field of examined dimensions of burnout syndrome, the most characteristic was emotional exhaustion, which has occurred with a frequency of nearly 30% and with typically high intensity among professionals working in neonatal intensive care units (N = 278). In addition, one-fifth were characterized by a high frequency and intensity of depersonalization. At the same time, nearly a third of them experienced a decrease in personal effectiveness. Workplace and time spent in healthcare did not show a significant connection with the incidence of burnout syndrome, however, burnout syndrome occurred with a higher frequency and intensity among those working in level III. neonatal intensive care unit. Conclusion: This is the first comprehensive burnout survey among premature and new born intensive care units in

Prevalence of Diabetes and Impaired Fasting Glycemia in Patients With Oral Cancer: A Retrospective Study in Hungary.

BACKGROUND/AIM: Diabetes mellitus (DM) is one of the most common chronic metabolic disorders. Our research aimed to demonstrate the relationship between DM and oral cancer. PATIENTS AND METHODS: We pursued a retrospective research study in Hungary between January 2019 and December 2020. We investigated 597 inpatient records and compared them to the results of our previous studies (1998-2002 and 2012-2015). RESULTS: The frequency of patients with DM in the oral cancer group is 2.45 times higher today than 20 years ago. The prevalence rate of DM and oral malignancies increased from 14.6% to 35.8%. In the oral cancer group, 54.4% of the patients had elevated blood glucose levels and of these, 61.1% of them had type 2 diabetes, 34.2% had impaired fasting glycemia, and only 4.7% had type 1 diabetes. We observed that 45.3% of them were smokers. Of those whose blood sugar levels were under 6.1 mmol/l, the mean body mass index was 25.33 [standard deviation (SD)=±4.5; range=15.57-39.84], while among patients with DM, it was 26.92 (SD=±5.8; range=18.36-44.08). CONCLUSION: It may be necessary to continuously monitor the patient's blood sugar level to maintain euglycemic levels when managing patients with malignant oral lesions.
