Radicular cysts are the most common inflammatory odontogenic cysts, typically arising from chronic periapical infection following pulp necrosis. Post-traumatic radicular cysts involving immature teeth with open apices are uncommon and present unique clinical challenges due to incomplete root formation. This case report describes the management of a large post-traumatic radicular cyst affecting multiple maxillary anterior teeth (teeth 11, 12, and 13) in a 27-year-old patient, discovered incidentally during routine radiographic examination.

Clinical examination revealed pulp necrosis and an open apex on tooth 11, with teeth 12 and 13 also non-vital. Radiographs and CBCT confirmed a well-demarcated radiolucent lesion with buccopalatal expansion and cortical bone resorption, consistent with a radicular cyst. Treatment included conventional root canal therapy for teeth 12 and 13, and apexification with Biodentine for tooth 11. Surgical enucleation of the cyst was performed via a full-thickness mucoperiosteal flap, achieving complete removal of the lesion.

Biodentine, a bioactive calcium silicate-based material, was used to create an apical plug, promoting hard tissue formation and providing a reliable apical barrier, thus facilitating root canal obturation in the immature tooth. Histopathology confirmed an inflammatory radicular cyst. At 13-month follow-up, the patient was asymptomatic, with radiographic evidence of significant bone regeneration, although a residual bony defect remained. Long-term follow-up was recommended to monitor complete healing and prevent recurrence.

This case highlights the importance of early diagnosis and a multidisciplinary approach combining modern endodontic materials and surgical intervention in managing post-traumatic radicular cysts involving open apex teeth, ultimately preserving tooth structure and function.

根状囊肿是最常见的炎症性牙源性囊肿，通常由牙髓坏死后的慢性根尖周感染引起。创伤后神经根囊肿涉及未成熟的牙齿开放的尖端是罕见的，目前独特的临床挑战，由于不完整的根形成。这个病例报告描述了一个27岁的病人在常规放射检查中偶然发现的创伤后大的根状囊肿，影响了多颗上颌前牙（第11、12和13颗牙齿）。临床检查发现第11颗牙牙髓坏死，牙尖裂开，第12、13颗牙也无生机。x线片和CBCT证实了一个界限清晰的透明病变，伴有颊腭扩张和皮质骨吸收，与根状囊肿一致。治疗包括12号和13号牙的常规根管治疗，11号牙的生物牙定根尖治疗。通过全层粘骨膜瓣手术摘除囊肿，实现病灶的完全切除。生物牙本质是一种生物活性的硅酸钙基材料，用于制造根尖塞，促进硬组织形成并提供可靠的根尖屏障，从而促进未成熟牙齿的根管封闭。组织病理学证实为炎症性神经根囊肿。在13个月的随访中，患者无症状，影像学证据显示骨再生明显，但仍有骨缺损残留。建议长期随访，监测完全愈合，防止复发。本病例强调了早期诊断和多学科方法结合现代根管材料和手术干预治疗创伤后根状囊肿的重要性，最终保留了牙齿的结构和功能。

Medication-related osteonecrosis of the jaw (MRONJ) is a significant complication associated with antiresorptive or antiangiogenic medications, particularly bisphosphonates and denosumab, commonly used in the management of osteoporosis and metastatic bone disease.

This retrospective service evaluation assessed treatment modalities and outcomes of MRONJ patients treated at the Royal London Dental Hospital (RLDH) between 2018 and 2023. A cohort of 53 patients, primarily oncology patients, were analysed, with 60 % of MRONJ sites presenting in the posterior mandible. Tooth extractions were identified as a leading precipitating factor in MRONJ development, while poor oral hygiene exacerbated disease progression.

Management strategies included conservative and operative interventions, with surgical debridement yielding a 70.6 % success rate in healing. Antibiotic therapy was prescribed in 50 % of stage 1 patients despite a lack of infection, highlighting the need to audit such use given the lack of evidence outside infection in stages 2 and 3.

This evaluation highlights the importance of preventive dental care, patient-centred personalised treatment planning, and the role of surgical interventions in MRONJ management.

药物相关性颌骨骨坏死（MRONJ）是与抗吸收或抗血管生成药物相关的重要并发症，特别是双磷酸盐和地诺单抗，通常用于骨质疏松症和转移性骨病的治疗。这项回顾性服务评估评估了2018年至2023年在皇家伦敦牙科医院（RLDH）治疗的MRONJ患者的治疗方式和结果。我们分析了53例患者，主要是肿瘤患者，其中60%的MRONJ位点出现在下颌骨后部。拔牙被确定为MRONJ发展的主要诱发因素，而不良的口腔卫生加剧了疾病的进展。治疗策略包括保守和手术干预，手术清创愈合成功率为70.6%。尽管没有感染，但仍有50%的1期患者开了抗生素治疗，这突出了考虑到2期和3期缺乏外部感染的证据，需要对这种使用进行审核。该评估强调了预防性牙科保健、以患者为中心的个性化治疗计划以及手术干预在MRONJ管理中的作用的重要性。

Injectable platelet-rich fibrin (i-PRF) has been proven to be able to promote tissue regeneration and applied in the treatment of diseases in the maxillofacial region, but whether it can be used to construct injectable tissue-engineered bone remains inconclusive. The aim of this study was to investigate whether i-PRF combined with osteoblastic bone marrow mesenchymal stem cell (BMSC) sheets can be used to construct injectable tissue-engineered bone. First, i-PRF prepared from fresh blood after a short-time and low-speed centrifugation. BMSCs, after continuous osteogenic induction for 2 weeks, formed membrane-like structures containing calcium nodules. They were mixed and then transplanted subcutaneously in nude mice by injection. the osteogenesis was evaluated through Micro-CT scanning and histological analysis after 8 weeks of transplantation. The group with BMSC sheets alone formed osteoid tissue, but the volume of new bone- and cartilage-like tissue was smaller, more sparse, and unevenly distributed. In contrast, the group with i-PRF and BMSC sheets had larger volumes of new tissue, higher bone density, more mineralized deposits, and more woven bone structures. In summary, osteoblastic BMSC sheets have the potential for ectopic osteogenesis, but i-PRF can significantly enhance their osteogenic capacity. Therefore, i-PRF combined with osteoblastic BMSC sheets can be regarded as a promising method for constructing injectable tissue-engineered bone.

可注射的富血小板纤维蛋白（i-PRF）已被证明能够促进组织再生并应用于颌面部区域疾病的治疗，但它是否可以用于构建可注射的组织工程骨仍然没有定论。本研究的目的是探讨i-PRF与成骨细胞骨髓间充质干细胞（BMSC）片是否可以用于构建可注射的组织工程骨。首先，从新鲜血液中提取短时间低速离心后制备i-PRF。骨髓间充质干细胞在连续成骨诱导2周后，形成含钙结节的膜样结构。将它们混合后注射到裸鼠皮下。移植8周后通过显微ct扫描和组织学分析评估成骨情况。单独使用BMSC片的组形成了类骨组织，但新生骨和软骨样组织体积更小，更稀疏，分布不均匀。相比之下，使用i-PRF和BMSC片的组具有更大的新组织体积，更高的骨密度，更多的矿化沉积物和更多的编织骨结构。综上所述，成骨骨髓间充质干细胞薄片具有异位成骨的潜力，但i-PRF可显著增强其成骨能力。因此，i-PRF与成骨骨髓间充质干细胞片相结合是一种很有前景的构建可注射组织工程骨的方法。

Background

Considering that specific anatomical features are frequently identified in Latin American Mestizo patients, it may be essential to modify existing procedures and design a rhinoplasty technique that can adjust to the anatomical needs of this population.

Objectives

This study aimed to propose a new modified technique in dorsal surface preservation rhinoplasty for patients with nasal morphology characteristic of Latin American Mestizo patients.

Methods

Patients were prospectively studied between July 2022 and July 2024. Data on age, gender, type of approach, need for touch-ups, surgery in conjunction with orthognathic surgery, and follow-up were recorded.

Results

We obtained a complete correction of the nasal humps with aesthetic changes, as proposed in the new technique developed and presented to 42 patients. This allowed a continuous and natural dorsum with a greater lateral definition of the dorsum, the definition of aesthetic lines, the shadow of the nasal pyramid breakage, and no evidence of bony steps of the central osteotomy.

Conclusions

The Modified Simplified Preservation Quick Rhinoplasty technique for Latin American Mestizo patients meets aesthetic and personalized standards without modifying the functionality and quality of life of patients. This technique enhances the morphologic qualities of the nasal anatomic structures of the patients, designing and molding the cartilaginous tissue that can be obtained efficiently.

背景：考虑到拉丁美洲混血人患者经常被识别出特定的解剖特征，可能有必要修改现有的手术程序并设计一种能够适应这一人群解剖需求的鼻整形技术。目的针对拉丁美洲混血儿鼻形态特点，提出一种新的保留鼻背面整形技术。方法于2022年7月至2024年7月对患者进行前瞻性研究。记录年龄、性别、入路类型、补片需求、手术与正颌手术结合以及随访等数据。结果我们获得了完整的鼻峰矫正与美学改变，在新技术中提出，并提出了42例患者。这允许一个连续和自然的背，更大的背侧轮廓，美学线条的定义，鼻金字塔断裂的阴影，没有中央截骨的骨台阶的证据。结论改进的简化保存快速隆鼻术在不改变患者功能和生活质量的情况下，满足拉丁美洲混血儿患者的审美和个性化标准。该技术提高了患者鼻解剖结构的形态学质量，有效地设计和塑造了可获得的软骨组织。

Aim

To evaluate efficacy of osseodensification on primary stability and final osseointegration of implants placed in areas of compromised bone density.

Material and methods

Study population comprised 10 patients, having D3/D4 type of bone. A total of 24 implants were placed in mandible and maxilla. The evaluation was carried out periodically for 1 year, investigating the influence of osteotomy technique using densah bur on clinical and radiographic parameters namely assessment of implant stability using torque wrench and osstell device, measurement of bone gain, bone expansion, bone density, bone surface area and crestal bone loss.

Results

The statistical analysis of torque wrench values at T0′ was 37.50(3.54SD) and 51.00(3.16SD) at T6 with p-value<0.001. The ISQ reading at T0′ was 62.8(3.4SD) and at T6 it was 65.8(5.4SD) p = 0.15,no significant difference seen. Considerable amount of bone gain post operatively noted (approx 26.8 %)p < 0.001. Evaluation of bone expansion in terms of ridge width demonstrated increase post-op(p < 0.001). Analysis of bone density in HU reveals significant increase at T6 p < 0.001. Bone surface area data tabulated at different intervals suggest increase post-op and at T6 (p < 0.05). The statistical data of crestal bone loss calculated periodically revealed 1.38 ± 0.41 at 12 months(p < 0.05).

Conclusion

Osseodensification using the versatile densah bur is a paradigm shift in the osteotomy preparation.

目的评价骨密度受损区骨增密对种植体初期稳定性和最终骨整合的影响。材料与方法研究人群为10例D3/D4型骨。在下颌骨和上颌骨共放置24个种植体。为期1年的定期评估，研究使用densah bur的截骨技术对临床和影像学参数的影响，即使用扭矩扳手和osstell装置评估种植体稳定性，测量骨增重、骨膨胀、骨密度、骨表面积和嵴骨损失。结果T0′时扭矩扳手值为37.50(3.54SD)， T6时为51.00(3.16SD)， p值为0.001。T0′时ISQ读数为62.8(3.4SD)， T6时为65.8(5.4SD), p = 0.15，差异无统计学意义。术后观察到相当数量的骨增重（约26.8%）p <；0.001. 根据脊宽评估骨扩张显示术后增加(p <；0.001)。HU骨密度分析显示T6 p <显著增高；0.001. 不同时间间隔骨表面积数据显示术后和T6时骨表面积增加(p <；0.05)。定期计算牙冠骨质流失统计数据：12个月1.38±0.41 (p <；0.05)。结论应用多用途骨密度器进行骨致密化是截骨准备的一种范式转变。

The aim of this study was to investigate the results of ameloblastoma treated at a single Cambodian institute during a 6-year period (Jan 2018–Dec 2023). A retrospective study was designed to include all patients who had been diagnosed with ameloblastoma and treated at the Department of Oral and Maxillofacial Surgery, Preah Ang Duong Hospital, Phnom Penh, Cambodia. Demographic details, location and size of lesion, histological classification of lesion by subtype, radiographic appearance, treatment and recurrence rates for up to 5 years were collated by using patients’ records and the histopathology database. 86 patients were included in the study. 75 (87.2 %) were located in the mandible, the most common size of ameloblastoma at presentation was 3.1–6 cm in 38 patients (44.2 %).

Sialolithiasis is one of the most common condition affecting the major salivary glands. This benign disorder is characterized by a partial or complete obstruction of the salivary glands or their ducts.

More than 80 % of salivary calculi occur in the submandibular ductal system. Parotid gland involvement is relatively rare, accounting for 5–10 % of cases. Its diagnosis is particularly challenging for the practitioners, which can lead to delayed diagnosis.

The aim of this article is to report a case of parotid sialolithiasis in Stenon's duct, diagnosed late after four years of recurrent acute sialadenitis episodes.

涎石症是影响主要唾液腺的最常见疾病之一。这种良性疾病的特征是部分或完全阻塞唾液腺或其导管。超过80%的唾液结石发生在下颌下导管系统。腮腺受累是相对罕见的，占病例的5 - 10%。它的诊断是特别具有挑战性的从业人员，这可能导致延误诊断。这篇文章的目的是报告一个病例腮腺涎石结石在斯顿管，诊断晚期后四年复发急性涎腺炎发作。

The purpose of this research is to identify the angle of pterygoid implant that have minimum equivalent stress and minimum equivalent strain using the finite element analysis (FEA) technique, based on the Frankfort Horizontal Plane. A three-dimensional maxilla model was reconstructed from a CT scan of a toothless patient. This model includes the cancellous and cortical bone. The facial region of a 58-year-old male patient with an atrophic maxilla and an angled pterygoid implant was imaged with CT in DICOM format. The raw DICOM data had a 0.3-mm section thickness. The MIMICS program created a three-dimensional model of the sections bone tissue. A dental implant with a diameter of 3.5 mm, a length of 16 mm, a conical shape, and a private thread design was placed in the pterygoid bone using SOLIDWORKS. This study investigated at how to place a pterygoid dental implant using both monocortical (at the end of the crest and cancellous bone) and bicortical (between the crest and basal bone) methods at 45, 55, 65, 75, and 85° relative to the Frankfort Horizontal Plane. Ten models were used for this study. CAD models were sent to ANSYS for loading. Boundaries of maxilla before force application are fixed from the zygomatic region. Human mastication was simulated using three load situations with the following characteristics, 150-N axial loading and 50-N lateral loading separately and 50-N lateral loading and 150-N axial loading simultaneously. Based on our studies and according to the Frankfort Horizontal Plane, placing the pterygoid implant at an 85° angle is the best in terms of bone stress. In terms of bone strain, it was found that placing the implant at 75 and 85° angles monocortically and bicortically respectively has the best outcome. This research concluded that an angle of 85° exhibits the minimum stress and strain effects on the surrounding bone tissue and the implant's structural integrity.

本研究的目的是利用基于法兰克福水平平面的有限元分析（FEA）技术，确定翼状假体具有最小等效应力和最小等效应变的角度。通过对无牙患者的CT扫描，重建了一个三维上颌骨模型。该模型包括松质骨和皮质骨。本文采用DICOM格式CT对58岁男性上颌萎缩、翼状骨倾斜植入患者的面部进行了影像学检查。原始DICOM数据的切片厚度为0.3 mm。MIMICS程序创建了骨组织切片的三维模型。使用SOLIDWORKS将直径为3.5 mm、长度为16 mm、圆锥形、专用螺纹设计的种植体放置在翼状骨内。本研究探讨了如何使用单皮质（在嵴和松质骨的末端）和双皮质（在嵴和基底骨之间）方法在相对法兰克福水平面45°、55°、65°、75°和85°放置翼状牙种植体。本研究共使用了10个模型。将CAD模型送入ANSYS进行加载。上颌用力前的边界从颧区固定。采用分别为150-N轴向加载和50-N侧向加载以及50-N侧向加载和150-N轴向加载的三种载荷情况模拟人类咀嚼行为。根据我们的研究，并根据法兰克福水平面，放置翼状骨种植体在85°角是最好的骨应力。在骨应变方面，我们发现单皮质和双皮质分别放置种植体75°和85°的角度效果最好。本研究得出的结论是，85°角对周围骨组织和种植体结构完整性的应力和应变影响最小。
