    背景:我们的目的是确定利用基于深度学习的全景X线照相术预测裂牙拔牙适应症的可行性。
    方法:评估了418颗牙齿(第1组:209颗正常牙齿;第2组:209颗裂纹牙齿)的全景X射线照片,以训练和测试深度学习模型。我们使用InceptionV3,ResNet50和EfficientNetB0评估了单个牙齿的裂纹诊断模型的性能。对裂牙诊断模型进行了五次交叉验证,将418个数据实例分为训练,验证,和测试集的比例为3:1:1。
    结果:为了评估可行性,灵敏度,特异性,准确度,并计算了深度学习模型的F1得分,值为90.43-94.26%,52.63-60.77%,72.01-75.84%,和76.36-79.00%,分别。
    结论:我们发现,通过使用全景射线照相术的深度学习模型,可以在一定程度上预测出现裂痕的拔牙适应症。
    BACKGROUND: We aimed to determine the feasibility of utilizing deep learning-based predictions of the indications for cracked tooth extraction using panoramic radiography.
    METHODS: Panoramic radiographs of 418 teeth (group 1: 209 normal teeth; group 2: 209 cracked teeth) were evaluated for the training and testing of a deep learning model. We evaluated the performance of the cracked diagnosis model for individual teeth using InceptionV3, ResNet50, and EfficientNetB0. The cracked tooth diagnosis model underwent fivefold cross-validation with 418 data instances divided into training, validation, and test sets at a ratio of 3:1:1.
    RESULTS: To evaluate the feasibility, the sensitivity, specificity, accuracy, and F1 score of the deep learning models were calculated, with values of 90.43-94.26%, 52.63-60.77%, 72.01-75.84%, and 76.36-79.00%, respectively.
    CONCLUSIONS: We found that the indications for cracked tooth extraction can be predicted to a certain extent through a deep learning model using panoramic radiography.

    下颌磨牙的矫正术伴随着重大挑战,特别是在成人和年轻的成人患者。在某些情况下,第三磨牙拔除程序提供的机会,放置微型板的支抗,以扩大下颌磨牙,为传统的拔除前磨牙或单切牙提供额外的解决方案。这种方法对成年患者特别感兴趣,他们可能有生活承诺和时间限制,限制了传统的正畸和手术治疗选择,它可以提高牙齿护理的效率。本病例系列描述了3种临床情况,其中在去除受影响的第三磨牙期间以最小的侵入性放置了微型板。为患者提供非传统的正畸治疗选择。对这些选择的认识对于普通牙医来说是至关重要的,这样他们就可以解释所有治疗的可能性,并为患有第三磨牙的患者提供适当的转诊。
    Distalization of mandibular molars comes with significant challenges, especially in adult and young adult patients. In selected cases, third molar extraction procedures offer the opportunity to place miniplates for anchorage to distalize mandibular molars, providing additional solutions to the traditional extraction of premolars or a single incisor. This approach can be of special interest to adult patients, who may have life commitments and time restraints that limit traditional orthodontic and surgical treatment options, and it can improve the efficiency of dental care. This case series describes 3 clinical scenarios in which miniplates were placed with minimal invasiveness during the removal of impacted third molars, offering the patients nontraditional orthodontic treatment options. Awareness of these options is essential for general dentists so that they can explain all treatment possibilities and provide appropriate referrals to patients with impacted third molars.

    本文的目的是报告一名5岁儿童患有多种牙齿异常的临床病例和4年随访,强调早期诊断和使用联合儿科手术和正畸方法的重要性。一个五岁的男孩,在他母亲的陪同下,寻求龋齿和牙齿疼痛的牙科护理。临床和影像学检查显示龋齿活跃,下颌右第二前磨牙区域的一个多余的乳牙,原发性下颌右第二磨牙严重强直。治疗计划包括拔除多余的牙齿以及切开和拔除坚固的磨牙。当病人6岁时,永久性下颌右第一磨牙显示出喷发过程改变的迹象,并开始正畸治疗。将带有螺旋弹簧的单侧带环空间保持器放置在第一磨牙上,该螺旋弹簧旨在移动第一磨牙。一张新的全景射线照片,患者7岁时获得,提示上颌右犬的顶端区域存在牙瘤。手术切除和病变的组织病理学检查证实这是一个正在发展的牙瘤。手术后,由于咬合异常,包括上颌横向缺损,深覆盖,和中线偏差,患者接受了Haas型矫治器的快速上颌扩张治疗.当病人8岁时,正畸治疗继续使用可移动的Hawley扩张器和正畸下颌舌弓。目前,在9岁的时候,在手术暴露受影响的永久性上颌右犬并结合正畸附件以进行牵引后,该儿童仍在接受固定正畸治疗。采用多学科方法管理牙齿异常可促进良好的预后,并确保对年轻患者进行全面治疗。
    The objective of this article is to report the clinical case and 4-year follow-up of a 5-year-old child with multiple dental anomalies, emphasizing the importance of early diagnosis and use of combined pediatric surgery and orthodontic approaches. A 5-year-old boy, accompanied by his mother, sought dental care for dental caries and tooth pain. Clinical and radiographic examinations revealed active caries, a supernumerary primary tooth in the region of the mandibular right second premolar, and severe ankylosis of the primary mandibular right second molar. The treatment plan involved extraction of the supernumerary tooth as well as sectioning and extraction of the ankylosed molar. When the patient was 6 years old, the permanent mandibular right first molar showed signs of an altered eruptive process, and orthodontic treatment was initiated. A unilateral band-and-loop space maintainer with coil springs designed to move the permanent first molar was placed on the primary first molar. A new panoramic radiograph, obtained when the patient was aged 7 years, suggested the presence of an odontoma in the apical region of the primary maxillary right canine. Surgical removal and histopathologic examination of the lesion confirmed that it was a developing odontoma. After surgery, due to occlusal anomalies that included transverse maxillary deficiency, deep overbite, and midline deviation, the patient underwent rapid maxillary expansion therapy with a Haas-type appliance. When the patient was 8 years old, orthodontic treatment continued with a removable palatal Hawley expander and a orthodontic mandibular lingual arch. Currently, at the age of 9 years, the child is still undergoing fixed orthodontic treatment after surgical exposure of the impacted permanent maxillary right canine and bonding of an orthodontic attachment to enable traction. A multidisciplinary approach to the management of dental anomalies promotes a favorable prognosis and ensures comprehensive treatment of young patients.

    这项建议的目的是(1)回顾目前的文献,(2)阐明制定普遍接受的指导方针的重要性,(3)在下颌第三磨牙(M3Ms)摘除的决策过程中提供帮助和指导,(4)降低由于M3M的不适当去除或保留而使患者遭受不必要伤害和并发症的风险。很明显,M3M的提取适应症将继续是一个有争议和激烈争论的领域。支持或反对预防性提取的证据是矛盾的;在某些特定情况下,有证据表明接受或拒绝反对预防性提取的立场,并且有发表的文章支持两种相反的观点。现有的第三磨牙拔除指南数量有限,并且大多是根据特定的设置或国家/地区量身定制的。没有可用的准则可以广泛用于帮助国际社会的决策过程。我们希望这项建议将是朝着建立普遍接受的指导迈出的重要的第一步。
    The aim of this proposal is to (1) review the current literature, (2) shed light on the importance of creating universally accepted guidelines, (3) provide help and guidance in the decision-making process with regard to the removal of mandibular third molars (M3Ms), and (4) reduce the risk of exposing the patient to unnecessary harm and complications due to the inappropriate removal or retention of M3Ms.It is obvious that the indications for the extraction of M3Ms will continue to be an area of controversy and strong debate. The evidence for or against prophylactic extraction is ambivalent; there is evidence to accept or reject the stance against prophylactic extraction in some specific cases, and there are published articles to support both opposing views. The available guidelines on the extraction of third molars are limited in number, and are mostly tailored to fit specific settings or countries. There are no available guidelines that might be widely used to help in the decision-making process for the international community. We hope this proposal will constitute an important first step toward creating universally accepted guidance.

    目的:评估和比较临床,放射学,以及两种方案之间的牙槽密封手术的组织学结果:脱蛋白脱矿质牙齿基质(dpDTM)和冻干同种异体骨(FDBA),每种都覆盖有游离的牙龈移植物。
    方法:将前磨牙区或前磨牙区的20个拔牙窝随机分配到dpDTM或FDBA方案中(每组n=10)。术后3个月,使用口内扫描仪和锥形束计算机断层扫描获得了牙槽变化的测量值。手术后三个月,安装了牙种植体(每组n=5),骨活检用于组织形态计量学和显微计算机断层扫描分析.在植入后3个月确定并比较植入稳定性商(ISQ)。
    结果:在3个月时,与FDBA组相比,dpDTM组中观察到颊牙槽脊高度和硬组织体积的降低较低(0.25±0.35mmvs.1.60±0.66mm[p=.000]和9.64±15.39%mm3vs.31.45±18.11%mm3[p=.010],分别)。同时,与FDBA组相比,dpDTM组中检测到较低的软组织体积减少(4.21±5.25%mm3vs.5.25±5.79%mm3)。dpDTM组(53.39±11.16%)和FDBA组(49.90±3.27%)之间的矿化组织形成百分比差异无统计学意义。尽管植入后3个月dpDTM组的ISQ值高于FDBA组,结果无统计学意义。
    结论:使用dpDTM保存牙槽脊是为开发功能性和美学植入物提供条件的有效方法。
    OBJECTIVE: To assess and compare the clinical, radiological, and histological outcomes of socket seal surgery between two protocols: deproteinized demineralized tooth matrix (dpDTM) and freeze-dried bone allograft (FDBA) each covered with a free gingival graft.
    METHODS: Twenty extraction sockets in the anterior or premolar region were randomly allocated to either the dpDTM or FDBA protocol (n = 10 per group). Measurements of the alveolar ridge changes were obtained using an intraoral scanner and cone-beam computed tomography at 3 months post-operation. Three-month post surgery, the dental implant was installed (n = 5 per group), bone biopsies were obtained for histomorphometrical and micro-computed tomography analyses. Implant stability quotients (ISQs) were determined and compared at 3 months post-implant.
    RESULTS: Lower significant reductions in buccal alveolar ridge height and hard tissue volume were observed in dpDTM group compared to FDBA group at 3 months (0.25 ± 0.35 mm vs. 1.60 ± 0.66 mm [p = .000] and 9.64 ± 15.39% mm3 vs. 31.45 ± 18.11% mm3 [p = .010], respectively). At the same time, lower soft tissue volume reduction was detected in the dpDTM group compared to FDBA group (4.21 ± 5.25% mm3 vs. 5.25 ± 5.79% mm3). No statistically significant difference in the percentage of mineralized tissue formation was found between dpDTM group (53.39 ± 11.16%) and FDBA group (49.90 ± 3.27%). Even though the ISQ in the dpDTM group showed a higher value than the FDBA group at 3 months post-implant, the results were without statistical significance.
    CONCLUSIONS: Alveolar ridge preservation using dpDTM is an efficacious procedure for providing the conditions for the development of functional and esthetic implants.

    背景:牙科医疗事故索赔,这涉及针对被指控对患者造成伤害的临床疏忽的牙医的法律诉讼,在过去的十年里,韩国的情况有所增加。索赔是由并发症引起的,尤其是三叉神经损伤,由于各种牙科手术。先前在韩国尚未描述与三叉神经损伤有关的医学问题。因此,在这项研究中,我们的目标是确定将军,牙科,以及封闭式牙科医疗事故索赔的司法特征。
    方法:本研究设计为描述性研究。我们收集了51项与牙科手术如牙种植体植入引起的三叉神经损伤相关的封闭索赔的数据,拔牙,和局部麻醉。这些索赔是在2016年至2023年之间由韩国法院裁决的。将军,牙科,并对索赔的司法特征进行了回顾性分析。
    结果:发生不良事件后的平均索赔解决期为4.2年(范围:1.47-8.39年),牙科诊所(68.6%)的发生率高于牙科(25.5%)或综合医院(5.9%)。牙科手术后,下肺泡(66.7%)和舌神经(17.6%)受伤。68.6%的索赔违反了告知义务。进行的牙科手术(P<0.001)和受伤的神经(P<0.001)与违反护理义务有关。
    结论:为了提高牙科护理服务质量,使用包括判断在内的各种资源对不良事件的分析应得到有力解决.
    BACKGROUND: Dental malpractice claims, which pertain to legal actions against dentists accused of clinical negligence that caused harm to patients, have increased in the past ten years in South Korea. The claims are caused by complications, particularly trigeminal nerve injuries, resulting from various dental procedures. Medicolegal issues related to trigeminal nerve injury have not been previously described in South Korea. Therefore, in this study, we aimed to identify the general, dental, and judicial characteristics of closed dental malpractice claims.
    METHODS: This study was designed as a descriptive study. We collected the data of 51 closed claims related to trigeminal nerve injury resulting from dental procedures such as dental implant emplacement, tooth extraction, and local anesthesia. The claims were decided by courts in South Korea between 2016 and 2023. The general, dental, and judicial characteristics of the claims were analyzed retrospectively.
    RESULTS: The average claim resolution period was 4.2 (range: 1.47-8.39) years post-adverse events that occurred more frequently in dental clinics (68.6 %) than in dental (25.5 %) or general hospitals (5.9 %). Inferior alveolar (66.7 %) and lingual (17.6 %) nerves were injured following dental procedures. The duty to inform was breached in 68.6 % of claims. The dental procedure performed (P < 0.001) and the injured nerve (P < 0.001) were associated with the violation of the duty to care.
    CONCLUSIONS: To improve the quality of dental care services, the analysis of the adverse events using various resources including judgments should be strongly addressed.

    目的:本研究的目的是比较白细胞和富血小板纤维蛋白(L-PRF)和光生物调节(PBM)的应用,一再被报道优于对照组,在疼痛方面,拔牙槽中的软组织和骨愈合。
    方法:这种双盲,随机临床研究完成了34例患者,他们有拔除双侧受累牙齿的指征。将患者的左右牙齿随机分为L-PRF组和PBM组。L-PRF组用血液制品以2700rpm离心12分钟,PBM组在不同的点用二极管激光治疗60s,波长为940nm,重复疗程。术后疼痛采用视觉模拟评分法(VAS)评估,软组织愈合与兰德里指数(LI),下颌第二磨牙远端区域的组织愈合通过探测深度测量,使用ImageJ程序通过全景X射线进行骨骼愈合。
    结果:两组之间的任何变量相比均无统计学意义的差异。
    结论:L-PRF和PBM应用在拔牙槽的愈合方面提供了类似的支持。然而,两种方法的优缺点决定了它们的使用领域。
    结论:虽然L-PRF在拔牙槽的早期愈合方面是有利的,就长期骨小梁形成而言,PBM可能是首选。
    OBJECTIVE: The aim of this study was to compare leukocyte and platelet-rich fibrin (L-PRF) and photobiomodulation (PBM) applications, which have been repeatedly reported to be superior to control groups, in terms of pain, soft tissue and bone healing in tooth extraction sockets.
    METHODS: This double-blind, randomized clinical study was completed with 34 patients, who had an indication for extraction of their bilaterally impacted teeth. The right and left teeth of the patients were randomly divided into L-PRF and PBM groups. L-PRF group was treated with the blood product centrifuged for 12 min at 2700 rpm, and the PBM group was treated with a diode laser at different points for 60 s with a wavelength of 940 nm in repeated sessions. Postoperative pain was evaluated using Visual Analogue Scale (VAS), soft tissue healing with Landry Index (LI), tissue healing in the distal region of mandibular second molar by probing depth measurement, and bone healing via panoramic x-ray using the Image J program.
    RESULTS: No statistically significant difference was found for any variable compared between the groups.
    CONCLUSIONS: L-PRF and PBM applications provide similar support in the healing of extraction sockets. Nevertheless, the advantages and disadvantages of both methods determine their usage areas.
    CONCLUSIONS: While L-PRF is advantageous in the early healing of extraction sockets, PBM may be preferred in terms of bone trabeculation in the long term.

    目的:我们旨在评估退伍军人事务医疗保健系统中抗生素预防与拔牙后不良结局之间的关系。
    方法:我们在2015-2019年对接受拔牙的患者进行了一项回顾性队列研究。主要暴露是抗生素预防。主要结果是7天内的拔牙后并发症(例如,肺泡骨炎和手术部位感染);次要结果是随后的医疗护理,涉及7天内拔牙后口腔并发症。多变量逻辑回归模型评估了抗生素预防对每个结果的独立影响。
    结果:在接受拔牙的385,880次访问中,122,810(31.8%)接受了抗生素预防。总的来说,3387(0.9%)经历了拔牙后并发症,350(0.09%)在7天内接受了与拔牙后口腔并发症相关的医疗护理。在多变量回归中,糖尿病是抗生素预防和拔牙后并发症之间关联的统计学显著(p=0.01)效应调节剂.在没有糖尿病的患者的就诊中,抗生素预防与拔牙后并发症几率增加显著相关(比值比[OR]=1.25,95%置信区间[CI]:1.13-1.38),但在糖尿病患者的访视中没有观察到显著的效果(OR=1.03,95%CI:0.92-1.15).抗生素预防与拔牙后的医疗护理没有显着相关(OR=1.04;95%CI:0.83-1.30)。
    结论:在这个大型回顾性队列中,我们观察到,在并发症发生率较低的情况下,抗生素预防对拔牙后并发症或后续医疗服务利用没有显著的保护作用.这些数据表明,在类似环境中使用抗生素预防可能需要重新评估,以尽量减少不必要的抗生素使用。
    OBJECTIVE: We aimed to evaluate the association between antibiotic prophylaxis and adverse outcomes following tooth extraction within the Veterans Affairs Healthcare System.
    METHODS: We conducted a retrospective cohort study of patients undergoing dental extractions in 2015-2019. The primary exposure was antibiotic prophylaxis. The primary outcome was post-extraction complication within 7 days (e.g., alveolar osteitis and surgical site infection); the secondary outcome was subsequent medical care relating to a post-extraction oral complication within 7 days. Multivariable logistic regression models assessed the independent effect of antibiotic prophylaxis on each outcome.
    RESULTS: Of 385,880 visits with a dental extraction, 122,810 (31.8%) received antibiotic prophylaxis. Overall, 3387 (0.9%) experienced a post-extraction complication and 350 (0.09%) received medical care relating to a post-extraction oral complication within 7 days. In multivariable regression, diabetes was a statistically significant (p = 0.01) effect modifier of the association between antibiotic prophylaxis and post-extraction complication. Among visits for patients without diabetes, antibiotic prophylaxis was significantly associated with an increased odds of post-extraction complication (odds ratio [OR] = 1.25, 95% confidence interval [CI]: 1.13-1.38), but among visits for patients with diabetes no significant effect was observed (OR = 1.03, 95% CI: 0.92-1.15). Antibiotic prophylaxis was not significantly associated with post-extraction medical care (OR = 1.04; 95% CI: 0.83-1.30).
    CONCLUSIONS: In this large retrospective cohort, we observed no significant protective effect of antibiotic prophylaxis on post-extraction complications or subsequent medical care utilization in a setting with low complication rates. These data suggest that use of antibiotic prophylaxis in similar settings may need to be re-evaluated to minimize unnecessary antibiotic use.

    目的:已将拔牙作为植骨的一种选择。然而,目前的方法需要特殊的机器和解决方案,构成显著的时间和成本。这项研究的目的是评估自体生牙颗粒(RTP)的临床表现,使用基本设备由地面牙齿制成的嫁接材料,用于牙槽骨的保存。
    方法:23名患者(12名研究/11名对照),研究和对照组(市售异种移植物)包括14和13个部位,分别。在基线和4个月随访时进行射线照相测量。此外,关于接受的移植物类型的一般偏好的问卷调查(如果需要),在知道价格之前和之后,在手术完成时分发,供患者回答。
    结果:研究组和对照组的肺泡脊宽度变化分别为-1.03±0.64和-0.84±0.35,分别。关于高度,研究组的颊部和舌部变化分别为-0.66±0.48和-0.78±0.81,而异种移植组为-0.78±0.56和-0.9±0.41。组间无统计学意义差异。与其他移植材料相比,患者更喜欢生齿颗粒(p=0.01)。
    结论:没有进行核心活检来评估骨形成,这应该在未来的研究中进行。在其局限性内,目前的研究表明,RTP移植物可能是骨增强的替代移植物,为临床医生提供新的成本效益选择。
    OBJECTIVE: The use of extracted teeth has been introduced as an option for bone grafting. However, the current method requires special machines and solutions, posing significant time and cost. The aim of this study was to evaluate the clinical performance of autogenous raw tooth particles (RTP), a grafting material made from a ground tooth using basic equipment, for alveolar ridge preservation.
    METHODS: Twenty-three patients (12 study/11 control), having 14 and 13 sites were included for the study and control groups (commercially available xenograft), respectively. Radiographic measurements were taken at the baseline and the 4-month follow-up appointment. Furthermore, a questionnaire survey concerning the general preference of the type of graft to receive (if needed), before and after knowing the price, was distributed at the completion of the procedure for patients to answer.
    RESULTS: Alveolar ridge width change was -1.03 ± 0.64 and -0.84 ± 0.35 for the study and the control groups, respectively. Regarding the height, the study group showed a buccal and lingual change of -0.66 ± 0.48 and -0.78 ± 0.81, respectively, while this was -0.78 ± 0.56 and -0.9 ± 0.41 for the xenograft group. There was no statistically significant difference between the groups. Patients preferred the raw tooth particles over other grafting materials (p = .01).
    CONCLUSIONS: No core biopsies were taken to evaluate bone formation, which should be done in future studies. Within its limitations, the current study demonstrated that RTP graft could be an alternative graft for bone augmentation, offering a new cost-effective option for clinicians when available.

    本报告的目的是讨论一名四岁的非洲裔美国女孩的病例,该女孩提供了局部III期C级牙周炎的临床和影像学证据。她没有全身性疾病或龋齿的病史。治疗包括口腔卫生指导,拔除无法挽救的牙齿,全口清创,使用全身抗生素和随后的牙周维护护理。病人接受了两年的随访,在此期间,疾病稳定,没有发现空间损失。虽然这种情况并不常见,儿科牙医必须能够早期诊断和治疗原发性牙列的牙周炎,与多学科团队一起,防止这种疾病在恒牙中复发。
    The purpose of this report is to discuss the case of a four-year-old African-American girl who presented with clinical and radiographic evidence of localized stage III grade C periodontitis. She had no history of systemic disease or caries. Treatment consisted of oral hygiene instructions, extraction of unsalvageable teeth, full-mouth debridement with the use of systemic antibiotics and subsequent periodontal maintenance care. The patient underwent a two-year follow-up, during which the disease was stabilized and no space loss was detected. Although this condition is uncommon, the pediatric dentist must be able to diagnose and treat periodontitis in the primary dentition early, together with a multidisciplinary team, to prevent a recurrence of this disease in the permanent dentition.
