Objective: Analyze factors influencing dentists' decisions to discard or submit tissues from tooth-associated lesions, such as those associated with impacted teeth and periapices, for histopathological analysis.

Study design: Cross-sectional study via online questionnaire with dentists, assessing practices regarding excised tissue management, sociodemographic and professional characteristics. Descriptive statistics, chi-square tests, Student's t-tests, and logistic regression were used for analysis, with significance at p < .05.

Results: Among 348 dentists (mean age 30.95 ± 9.24 years), 65.8% were female, 58.05% held postgraduate degrees, and 67.53% worked in private clinics. Most participants (85.63%) reported not submitting tooth-associated lesions for histopathological examination. Significant associations with tissue submission included, during dental education: access to pathology laboratories, exposure to anatomopathological reports, and perception of sufficient training in oral pathology and oral medicine. In professional practice, prior experience with biopsy requisition forms and exposure to anatomopathological reports were significant. Logistic regression identified 2 significant predictors of tissue submission: perception of sufficient training in oral pathology and oral medicine during dental education, and exposure to anatomopathological reports in professional practice.

Conclusions: Although histopathology is crucial for diagnosis, tissue discard remains frequent. These findings highlight the importance of strengthening dental education and clinical training in management of excised tissues in dentistry.

目的：分析影响牙医决定丢弃或提交牙齿相关病变组织（如与阻生牙和尖周相关的病变组织）进行组织病理学分析的因素。研究设计：通过与牙医的在线问卷调查进行横断面研究，评估有关切除组织管理、社会人口统计学和专业特征的做法。采用描述性统计、卡方检验、学生t检验和逻辑回归进行分析，p < 0.05为显著性。结果：348名牙医（平均年龄30.95±9.24岁）中，女性占65.8%，研究生学历占58.05%，在私人诊所工作的占67.53%。大多数参与者（85.63%）报告没有提交牙齿相关病变进行组织病理学检查。在牙科教育过程中，与组织提交相关的重要因素包括：进入病理实验室，接触解剖病理报告，以及在口腔病理学和口腔医学方面接受足够的培训。在专业实践中，活检申请表和解剖病理报告的经验是重要的。逻辑回归确定了组织提交的2个重要预测因素：在牙科教育中接受足够的口腔病理学和口腔医学培训，以及在专业实践中接触解剖病理学报告。结论：虽然组织病理学对诊断至关重要，但组织丢弃仍然是常见的。这些发现强调了加强牙科教育和牙科切除组织管理临床培训的重要性。

Objective

We evaluated the effectiveness of dynamic contrast-enhanced magnetic resonance imaging (MRI) in distinguishing vital and non-vital teeth using a time-intensity curve pattern.

Study Design

We retrospectively analyzed patients who underwent dynamic contrast-enhanced MRI examinations, including those with jaw lesions and vital test results. The vital status of the dental pulp was assessed using the electric pulp test. MRI was performed using a 3T scanner and a 16-channel head and neck coil, with intravenous administration of gadoterate meglumine. Two radiologists measured signal intensity using T1-weighted imaging, T2-weighted imaging, and gadolinium-enhanced T1-weighted imaging, while time-intensity curve classification was evaluated using time-resolved angiography with interleaved stochastic trajectory images.

Results

We analyzed 26 vital and 15 non-vital teeth, using the signal- and time-intensity curve classifications. Signal intensity measurements showed no significant differences between vital and non-vital teeth on T1-weighted imaging, gadolinium-enhanced T1-weighted imaging, and T2-weighted imaging. Time-intensity curve classification effectively distinguished between increasing- and non-increasing-type teeth. Only one case showed a discrepancy between the time-intensity curve and electric pulp test, but accuracy remained high at 98%.

Conclusion

Time-intensity curves derived from dynamic contrast-enhanced MRI accurately differentiated vital from non-vital teeth in jawbone lesions, comparable to the electric pulp test.

目的：我们评估动态对比增强磁共振成像（MRI）在使用时间-强度曲线模式区分重要和非重要牙齿方面的有效性。研究设计：我们回顾性分析了接受动态对比增强MRI检查的患者，包括颌骨病变和重要检查结果的患者。用电牙髓试验评估牙髓的生命状态。使用3T扫描仪和16通道头颈线圈进行MRI检查，静脉注射钆酰亚胺。两名放射科医生使用t1加权成像、t2加权成像和钆增强t1加权成像测量信号强度，同时使用交错随机轨迹图像的时间分辨血管成像评估时间强度曲线分类。结果：采用信号曲线和时间强度曲线分类，分析了26颗活牙和15颗非活牙。信号强度测量显示，在t1加权成像、钆增强t1加权成像和t2加权成像上，生命牙和非生命牙之间无显著差异。时间-强度曲线分类能有效区分递增型和非递增型齿。只有1例的时间-强度曲线与电牙髓试验存在差异，但准确率仍高达98%。结论：动态增强MRI的时间-强度曲线可准确区分颌骨病变中的重要牙和非重要牙，可与电牙髓试验相媲美。

Objective

This study investigates the use of neural networks to predict potential osteoporotic metabolic conditions using the Panoramic Mandibular Index (PMI) derived from panoramic radiographs.

Study Design

A total of n = 750 radiographs were collected and 1,500 regions of interest (ROIs) were analysed. Convolutional neural network (CNN), specifically ResNet-50, were used with transfer learning, achieving the highest accuracy. Three classification approaches were tested: binary classification (PMI > 0.25 vs. PMI < 0.25), 3-class classification (PMI > 0.25, 0.2-0.25, PMI < 0.2), and a modified 2-class classification (PMI > 0.25 vs. PMI < 0.2).

Results

The best classification, the modified 2-class classification, achieved an accuracy of 89.5%. Data augmentation techniques including rotation, reflection, and scaling, improved model robustness.

Conclusions

This study demonstrates that a neural network can be trained to effectively classify PMI values in panoramic radiographs, providing an easy applicable and noninvasive method to identify patients at risk of osteoporosis.

目的：本研究探讨利用全景x线片得出的下颌全景指数（PMI），利用神经网络预测潜在的骨质疏松代谢状况。研究设计：共收集了n = 750张x线片，分析了1,500个感兴趣区域（roi）。卷积神经网络（CNN），特别是ResNet-50与迁移学习一起使用，达到了最高的准确率。测试了三种分类方法：二元分类（PMI > 0.25 vs PMI < 0.25），三级分类（PMI > 0.25, 0.2-0.25, PMI < 0.2）和改进的二级分类（PMI > 0.25 vs PMI < 0.2）。结果：最佳分类方法为改进的2类分类，准确率为89.5%。数据增强技术，包括旋转、反射和缩放，提高了模型的鲁棒性。结论：本研究表明，神经网络训练可以有效地对全景x线片PMI值进行分类，为识别骨质疏松风险患者提供了一种简单适用且无创的方法。

Objective: This study aimed to evaluate the influence of trabecular bone microstructure on the accuracy of dental implant placement using dynamic navigation.

Study design: Thirty-seven implants were placed in 35 patients. Bone biopsies were analyzed to measure bone volume fraction (BV/TV), trabecular thickness (Tb.Th), number (Tb.N), and separation (Tb.Sp). Implant deviations were assessed with navigation software.

Results: BV/TV showed a significant negative correlation with apical (r = -0.396, P < .05) and angular deviation (r = -0.402, P < .05), but not with coronal deviation. Critically, no other parameters (Tb.Th, Tb.N, Tb.Sp) demonstrated any significant correlation with implant positioning accuracy (all P > .05). Multivariate analysis confirmed BV/TV as the sole significant predictor of angular deviation (β = -0.079, P < .05).

Conclusion: While higher bone volume fraction improves angular accuracy, other trabecular microstrctural parameters do not significantly influence placement precision under dynamic navigation.

目的：探讨骨小梁微结构对动态导航种植体定位精度的影响。研究设计：在35例患者中放置37个植入物。骨活检测定骨体积分数（BV/TV）、骨小梁厚度(Tb。Th)，数（Tb）N)和分离（Tb.Sp）。使用导航软件评估种植体偏差。结果：BV/TV与冠状偏移呈显著负相关（r = -0.396, P < 0.05），与冠状偏移呈显著负相关（r = -0.402, P < 0.05）。关键是，没有其他参数(Tb。Th,结核病。N,结核病。Sp)显示与种植体定位精度有显著相关性（均P < 0.05）。多因素分析证实BV/TV是角偏差的唯一显著预测因子（β = -0.079, P < 0.05）。结论：在动态导航下，较高的骨体积分数可以提高骨小梁的角度定位精度，而其他骨小梁微观结构参数对骨小梁的定位精度影响不显著。

Objectives: To evaluate the radiation dose in the oral cavity structures (through in vivo dosimetry and treatment planning system) of head and neck cancer patients; and secondarily, evaluate sialometry and oral mucositis.

Study design: This is a prospective cohort study with patients over 18 years old, diagnosed with oral cavity and major salivary glands cancer, treated with radiotherapy. Group A patients used an intraoral stent (n = 14), and those in Group B (n = 14) did not. In Group A, in vivo dosimetry was performed by positioning 2 thermoluminescent dosimeters in the intraoral stent; unstimulated and stimulated salivary flow were measured; and oral mucositis was evaluated.

Results: In vivo dosimetry demonstrated higher doses in the tumoral area in comparison with the opposite tumor area (p < .001). The planning system predicted doses in nontumor area were lower in Group A. Unstimulated sialometry was higher in Group A in the intermediate and final sessions (p < .05), and hyposalivation was more frequent in Group B (p = .015). No statistically significant differences were observed between the groups regarding the maximum grade and duration of oral mucositis (p = .499; and p = .466, respectively).

Conclusion: The intraoral stent was associated with opposite tumor area lower doses, measured using in vivo dosimetry, the first time this method was applied in studies on this device. Individuals treated with the intraoral stent presented higher salivary flows during and after radiotherapy.

目的：通过体内剂量法和治疗计划系统评价头颈癌患者口腔结构中的辐射剂量；其次，评估唾液测量和口腔黏膜炎。研究设计：这是一项前瞻性队列研究，患者年龄超过18岁，诊断为口腔和大唾液腺癌，接受放疗。A组患者使用了口内支架（n = 14）， B组患者（n = 14）未使用。A组在口腔内支架内放置2个热释光剂量仪进行体内剂量测定；测量未受刺激和受刺激的唾液流量；评估口腔黏膜炎。结果：体内剂量测定显示肿瘤区剂量高于对面肿瘤区（p < 0.001）。计划系统预测的非肿瘤区域的剂量在A组较低（p < 0.05），非刺激的唾液测量在中间和最后阶段在A组较高（p < 0.05），低渗在B组更频繁（p = 0.015）。两组口腔黏膜炎的最大程度和持续时间差异无统计学意义（p = 0.499; p = 0.466）。结论：口腔内支架与肿瘤对面区域低剂量相关，采用体内剂量法测量，该方法首次应用于该装置的研究。接受口内支架治疗的个体在放疗期间和放疗后出现较高的唾液流量。

Objectives: This study evaluates the implications of clinical and radiographic diagnostic errors on the treatment of non-endodontic and truly endodontic periapical lesions, as determined by histopathologic findings.

Study design: A retrospective review was conducted on 236 histopathological reports of periapical lesions collected via apical surgery, extraction, or cystectomy (2020-2024). Clinical diagnoses based on 2-dimensional radiographs and CBCT were compared with histopathological results. Cases with soft tissue lesions, lesions with no detectable radiographic findings, or non-periapical pathoses were excluded. Data were categorized and statistically analyzed to determine diagnostic accuracy.

Results: Of 236 cases, 136 (57.62%) were of endodontic origin (apical granulomas and radicular cysts), while 100 (42.37%) were nonendodontic, including 56 (23.73%) odontogenic cysts, 18 (7.63%) tumors, 16 (6.78%) non-odontogenic cysts, and 10 (4.24%) fibro-osseous lesions. Misdiagnosis led to inappropriate treatments such as unnecessary extractions or ineffective root canal therapy. CBCT with histopathological confirmation significantly improved diagnostic precision. Notably, 63 (26.79%) of teeth linked to odontogenic cysts were vital, indicating that root canal therapy was unwarranted.

Conclusions: Based on the findings of this retrospective study, a substantial proportion of periapical lesions are non-endodontic, emphasizing the importance of clinical evaluation, including vitality testing, alongside imaging in the differential diagnosis as opposed to reliance on imaging alone. Reliance solely on imaging can cause treatment errors. Improved protocols and further research are essential to optimize outcomes.

目的：本研究评估临床和影像学诊断错误对治疗非根管和真根管根尖周病变的影响，根据组织病理学结果确定。研究设计：对2020-2024年通过根尖手术、摘除或膀胱切除术收集的236例根尖周围病变的组织病理学报告进行回顾性分析。将基于二维x线片和CBCT的临床诊断与组织病理学结果进行比较。排除有软组织病变、无放射学发现的病变或非根尖周围病变的病例。对数据进行分类和统计分析，以确定诊断的准确性。结果：236例患者中，牙髓源性（根尖肉芽肿和根状囊肿）136例（57.62%），非牙髓源性100例（42.37%），其中牙源性囊肿56例（23.73%），肿瘤18例（7.63%），非牙髓源性囊肿16例（6.78%），纤维骨性病变10例（4.24%）。误诊导致不适当的治疗，如不必要的拔牙或无效的根管治疗。经组织病理学证实的CBCT可显著提高诊断精度。值得注意的是，63（26.79%）与牙源性囊肿相关的牙齿是至关重要的，这表明根管治疗是没有根据的。结论：基于本回顾性研究的结果，相当大比例的根尖周病变是非根管性的，强调临床评估的重要性，包括活力测试，以及鉴别诊断时的影像学检查，而不是仅仅依赖影像学检查。仅仅依赖影像可能导致治疗错误。改进的方案和进一步的研究对于优化结果至关重要。

Oral and Maxillofacial Surgery (OMS) residency programs in the United States have recently experienced a notable decline in match rates. While it may be challenging to identify the root cause of this change, similar experiences in other specialties have identified contributing factors such as the increase in the number of residency positions, changes in specialty perception and workforce needs as contributing factors. This article examines the current state of OMS residency training and provides recommendations aimed to attract more people to the field, take a deeper dive into understanding of the factors contributing to changes in the specialty, and the development of evidence-based interventions.

口腔颌面外科（OMS）住院医师计划在美国最近经历了一个显着下降的匹配率。虽然确定这种变化的根本原因可能具有挑战性，但其他专业的类似经验已经确定了影响因素，如住院医师职位数量的增加、专业认知的变化和劳动力需求的变化。本文考察了OMS住院医师培训的现状，并提出了一些建议，旨在吸引更多的人进入该领域，深入了解导致该专业变化的因素，并开发基于证据的干预措施。
