A beautiful smile boosts a person's confidence. Gummy smile is a term used for excessive gingival display (EGD), its etiology is multifactorial, can be treated by several surgical and non-surgical techniques due to etiology factors. Factors that contribute to the gummy smile include exaggerated lip length and lip hypermobility. Lip repositioning surgery can be used to treat EGD, mild to moderate degree of gingival display (4-8 mm) caused by hypermobile upper lip. The lip repositioning procedure is a surgical treatment option that involves removing a partial thickness strip from the maxillary buccal vestibular mucosa and suturing the lip mucosa back to the mucogingival line. This technique is less invasive than orthognathic surgery, with minor complications and patient satisfaction.
美丽的笑容能增强人的自信心。牙龈笑是指牙龈过度显示(EGD),其病因是多因素的,由于病因的不同,可以通过多种手术和非手术技术进行治疗。导致牙龈笑的因素包括嘴唇长度过长和嘴唇活动度过大。唇部复位手术可用于治疗因上唇活动度过大而导致的牙龈外露、轻度至中度牙龈外露(4-8 毫米)。唇部复位手术是一种外科治疗方法,包括从上颌颊前庭粘膜上切除部分厚度的条状粘膜,然后将唇部粘膜缝合回粘龈沟。与正颌外科手术相比,这种技术创伤小,并发症少,患者满意度高。

A Schwannoma (Neurilemmoma) is a benign nerve tumor arising from a myelinated nerve fibers sheath, that can appear in any part of the body. Forty-five percent of the cases occur in the head and neck region. Intraoral Schwannomas are rather uncommon, intranasal and intrasinus Schwannomas are even rarer (less than 1%). The clinical case reports a young, man 14-years-old male with a Neurilemmoma the left maxillary sinus, involving the left third molar. The reports include case information, radiological findings, the surgery treatment, the histological characteristics of this particular tumor, a differential diagnosis, the post-operation process, and a review of the available literature.
许旺瘤(神经纤维瘤)是一种良性神经肿瘤,由有髓鞘的神经纤维鞘产生,可出现在身体的任何部位。45%的病例发生在头颈部。口内许旺瘤并不常见,鼻内和窦内许旺瘤则更为罕见(少于 1%)。本临床病例报告了一名 14 岁的年轻男性,其左上颌窦患有神经瘤,累及左侧第三磨牙。报告内容包括病例信息、放射学检查结果、手术治疗、该特殊肿瘤的组织学特征、鉴别诊断、术后过程以及现有文献综述。

During the COVID-19 pandemic, there was a notable increase in cases of oral mucormycosis, with some researchers linking corticosteroid treatment to immune suppression, potentially increasing susceptibility to this fungal infection. Early oral manifestations may serve as indicators for timely diagnosis. This protocol for a systematic review aims to elucidate the pathogenesis and related factors of post-COVID-19 mucormycosis through the analysis of case reports. We will conduct a comprehensive search of relevant articles, excluding review articles and case series. Bias risk will be assessed using the ROBINS-E tool, and certainty of evidence will be evaluated using the GRADE framework. A narrative synthesis of the data will be performed, focusing on sociodemographic profiles, medical and family histories, diagnostic methods, treatment approaches, and dental relevance.

Background: During the endodontic process, cleaning and shaping are essential steps. The fracture of nickel-titanium (NiTi) tools is a procedural issue that significantly impedes therapy in normal endodontic therapy. Efficient and reliable endodontic therapy requires rotary NiTi files that demonstrate superior cyclic fatigue resistance to prevent file separation within the canal. This study aimed to investigate the in-vitro cyclic fatigue resistance of two commonly used rotary NiTi files: NeoEndo Flex file and ProTaper Gold file. Methods: The cyclic fatigue tests were carried out by determining the lifespan of each file type in a controlled environment mimicking a curved root canal. A total of 30 files (15 NeoEndo Flex and 15 ProTaper Gold) were subjected to continuous rotation until fracture occurred. The numbers of cycles until failure (NCF) were recorded for statistical comparison. Results: The ProTaper Gold files showed significantly higher NCF, indicative of stronger cyclic fatigue resistance when compared to NeoEndo Flex files (p < 0.05). The variance in fatigue resistance is attributable, in part, to differences in alloy composition and proprietary heat treatment processes. Conclusion: ProTaper Gold rotary NiTi files exhibited enhanced cyclic fatigue resistance in comparison to NeoEndo Flex, suggesting that they may be the preferred choice for clinical procedures where greater stresses are anticipated on the file. However, clinicians should balance file strength with other clinical factors when choosing the appropriate file for endodontic treatment.
背景:在牙髓治疗过程中,清洁和塑形是必不可少的步骤。镍钛(NiTi)工具的断裂是一个程序问题,严重阻碍了正常的牙髓治疗。高效可靠的根管治疗需要旋转镍钛锉表现出卓越的抗循环疲劳性能,以防止锉片在根管中分离。本研究旨在调查两种常用旋转式镍钛锉的体外循环抗疲劳性:NeoEndo Flex锉和ProTaper Gold锉。方法:循环疲劳试验是在模拟弯曲根管的受控环境中测定每种锉刀的使用寿命。共对 30 支锉刀(15 支 NeoEndo Flex 和 15 支 ProTaper Gold)进行连续旋转,直至发生断裂。记录直至失效的循环次数(NCF),以便进行统计比较。结果:与NeoEndo Flex锉相比,ProTaper Gold锉的NCF明显更高,表明其具有更强的抗循环疲劳性(p < 0.05)。抗疲劳性的差异部分归因于合金成分和专有热处理工艺的不同。结论与 NeoEndo Flex 相比,ProTaper Gold 旋转镍钛锉表现出更强的抗循环疲劳性,这表明在临床手术中,如果锉上预计会有更大的应力,ProTaper Gold 旋转镍钛锉可能是首选。不过,临床医生在为牙髓治疗选择合适的锉刀时应平衡锉刀强度和其他临床因素。

Objective: This case report aims to present how to fabricate a new restoration to match existing odd-shaded ones. Clinical considerations: A polycarbonate provisional crown was used to produce a cement-retained immediate load provisional restoration over an implant of tooth number #9. Using a color correcting light source, it was noticed that existing restorations had very high value with excess gray hue. XL2 of Premise composite shade tab was the closest match found, and the base shade for the custom-made restoration. Once no shade match was found in commercially available shade guides, there was a demand to produce a custom-made shade to address this case. The facial surface of the provisional crown was prepared as a veneer. Utilizing XL2 Premise composite and adding different amounts of gray color modifier, shade matching was fulfilled by mixing the composite and the color modifier. In this case, five attempts were made to achieve color match. The restoration was polished utilizing Soflex Discs. Provisional crown was in function for 12 weeks. Conclusions: By implementation of the principles of color, restorative materials and characterization kits, the new temporary restoration could match the existing ones using the technique described in this case report.
目的:本病例报告旨在介绍如何制作一个新的修复体,以匹配现有的异色修复体。临床考虑因素:在 9 号牙的种植体上使用聚碳酸酯临时冠制作一个粘结固位的即刻负荷临时修复体。使用校色光源时发现,现有修复体的色值非常高,灰色色调过多。Premise 复合材料色卡的 XL2 是最接近的匹配色,也是定制修复体的基础色。由于在市面上的色调指南中找不到匹配的色调,因此需要定制一种色调来解决这个病例。临时牙冠的面部被制作成贴面。使用 XL2 Premise 复合材料并添加不同量的灰色改色剂,通过混合复合材料和改色剂来实现色调匹配。在这个病例中,为了达到颜色匹配,共尝试了五次。修复体使用 Soflex 盘抛光。临时冠的功能维持了 12 周。结论:通过执行颜色、修复材料和特征工具包的原则,使用本病例报告中描述的技术,新的临时修复体可以与现有的修复体相匹配。

Aim: To comparatively evaluate postoperative pain levels following root canal instrumentation with hand files versus Pedoflex rotary files in primary mandibular molars. Material and Methods: This randomized clinical trial involved 60 children aged 6-10 years with primary mandibular molars requiring pulpectomy. They were divided into two groups: Group I received hand K file instrumentation, and Group II was treated with Pedoflex rotary files. Pain levels were recorded using the Wong-Baker FACES Pain Rating Scale at 6, 12, 24, 48, and 72 hours postoperatively. Results: The Pedoflex rotary file group experienced significantly lower pain scores at all time intervals compared to the hand K file group (p<0.05). The mean pain score in Group A gradually decreased from 6 to 72 hours, while Group B showed a more rapid decline in the first 24 hours followed by a plateau. Conclusion: The use of Pedoflex rotary files for root canal instrumentation in primary mandibular molars significantly reduces postoperative pain when compared to conventional hand files. These findings suggest that rotary files may provide a more comfortable postoperative experience for pediatric patients undergoing pulpectomy
目的:比较评估使用手动锉和 Pedoflex 旋转锉对初级下颌磨牙进行根管器械治疗后的术后疼痛程度。材料与方法:这项随机临床试验涉及 60 名 6-10 岁需要进行牙髓切除术的原发性下颌磨牙患儿。他们被分为两组:第一组接受手工K锉器械治疗,第二组使用Pedoflex旋转锉治疗。在术后 6、12、24、48 和 72 小时,使用 Wong-Baker FACES 疼痛评分量表记录疼痛程度。结果:在所有时间间隔内,Pedoflex 旋转锉组的疼痛评分均明显低于手 K 锉组(P<0.05)。A 组的平均疼痛评分在 6 至 72 小时内逐渐下降,而 B 组在最初的 24 小时内下降较快,随后趋于平稳。结论与传统手工锉相比,使用 Pedoflex 旋转锉进行下颌磨牙根管器械治疗可显著减少术后疼痛。这些研究结果表明,旋转锉可以为接受牙髓切除术的儿童患者提供更舒适的术后体验。

The complex odontoma is a benign odontogenic tumor of the jaw, consisting of a disorganised mass of dental tissue with unknown aetiology. They are often asymptomatic and usually identified incidentally upon radiographic examination. However, they have the potential to cause displacement and resorption of adjacent teeth as well as affecting tooth eruption, therefore early identification is important. We report a case of a 12 year old male who was referred to our department with an incidental finding of a complex odontoma in the mandible.
复合牙瘤是颌骨的一种良性牙源性肿瘤,由病因不明的紊乱牙组织块组成。它们通常没有症状,通常在放射检查时偶然发现。然而,它们有可能导致邻近牙齿移位和吸收,并影响牙齿的萌出,因此早期识别非常重要。我们报告了一例 12 岁男性的病例,他因偶然发现下颌骨有一个复杂的牙瘤而被转诊到我们科室。

Patients receiving oral anticoagulant therapy are at an increased risk of bleeding complications, necessitating effective hemostatic interventions. This study aims to evaluate and compare the efficacy of four hemostatic agent (figure of eight suturing, Absorbable gelatin sponge (ABGEL), Topical application of hemocogulase, and pressure gauze pack) in achieving hemostasis among patients on oral anticoagulant therapy. The study was conducted on 100 patients which were randomly divided in four groups and we found that all methods of achieving hemostasis are equally beneficial.
接受口服抗凝剂治疗的患者发生出血并发症的风险增加,因此有必要采取有效的止血干预措施。本研究旨在评估和比较四种止血剂(八字形缝合、可吸收明胶海绵(ABGEL)、局部应用血凝酶和加压纱布包)在口服抗凝疗法患者中的止血效果。我们发现,所有止血方法都同样有益。
