Introduction: Acute apical abscesses are known for rapid-onset pain and swelling from pulp necrosis. While typically associated with polymicrobial infections, recent research suggests that active herpesvirus infections may also contribute. This randomized, double-blind, placebo-controlled trial aimed to evaluate if valacyclovir, when combined with amoxicillin, can consistently manage pain and how individual patients respond within a larger population.

Methods: This study enrolled 38 emergency patients with moderate to severe pain from acute apical abscesses, randomizing them into 2 treatment groups. Patients in the valacyclovir group (n = 21) received a 1g loading dose of amoxicillin (followed by 500 mg four times daily for 7 days) and a 2g loading dose of valacyclovir (followed by 500 mg twice daily for 3 days). The placebo group (n = 17) received the same amoxicillin regimen along with a placebo. Over a 6-day follow-up, we used daily phone calls to track pain levels with a numeric rating scale and monitor analgesic use. Outcome data were analyzed using the Mann-Whitney and Friedman statistical tests.

Results: The valacyclovir group showed significantly lower mean pain scores on Days 1-3 (P < .05). They experienced a faster reduction in moderate/severe pain and a higher rate of reporting no pain (numeric rating scale= 0) throughout the study. Analgesic use dropped sharply in the valacyclovir group, with only 28.6% using analgesics on Day 1 compared to 82.4% in the placebo group. This consistently lower usage was maintained through Day 6.

Conclusion: Valacyclovir shows promise as an adjunctive therapy for early pain relief in patients with acute apical abscesses.

简介：急性根尖脓肿（AAAs）以牙髓坏死引起的快速疼痛和肿胀而闻名。虽然通常与多微生物感染有关，但最近的研究表明，活动性疱疹病毒感染也可能起作用。这项随机、双盲、安慰剂对照试验旨在评估valacyclovir与阿莫西林联合使用时是否能持续治疗疼痛，以及个体患者在更大人群中的反应如何。方法：本研究纳入38例因急性根尖脓肿引起的中度至重度疼痛的急诊患者，将其随机分为两个治疗组。瓦昔洛韦组（n=21）患者给予阿莫西林1g负荷剂量（随后500mg每日4次，连续7天）和瓦昔洛韦2g负荷剂量（随后500mg每日2次，连续3天）。安慰剂组（n=17）在服用安慰剂的同时给予相同的阿莫西林治疗。在为期6天的随访中，我们使用每日电话记录，用数字评定量表（NRS）跟踪疼痛水平，并监测止痛药的使用情况。结果数据采用Mann-Whitney和Friedman统计检验进行分析。结果：valacyclovir组在第1-3天的平均疼痛评分显著降低(p结论：valacyclovir有望作为急性根尖脓肿患者早期疼痛缓解的辅助治疗。

Long-term dental defects are often accompanied by severe alveolar bone resorption, which compromises the maintenance of alveolar bone height and thickness, thereby increasing the complexity of restoration. This case report presents a 24-year-old female patient with a 6-month dental defect and alveolar bone resorption. The treatment consisted of autotransplanting the left mandibular third molar to the defect site, with the use of a three-dimensional printed donor tooth replica and the surgical guide for precise alveolar socket preparation. Simultaneously, autogenous bone harvested intraoperatively was transplanted to the buccal bone defect area. Root canal treatment was performed 2 weeks postoperatively. A 21-month follow-up demonstrated a stable transplanted tooth, satisfactory buccal bone regeneration, and notable esthetic improvement. This case highlights the potential benefits of integrating digital technology with autogenous bone grafting in autotransplantation of teeth for complex dentition defects.

Introduction

To identify patient-specific phenotypic, anatomical, psychological, and clinical risk factors associated with the development of post-traumatic trigeminal neuropathy (PTTN) following endodontic procedures.

Methods

This systematic review was conducted following PRISMA 2020 guidelines, with the protocol prospectively registered in PROSPERO (CRD420251071354). Searches were performed in PubMed/MEDLINE and LILACS (via BVS) up to June 2025. Studies were eligible if they reported patient-level phenotypic, anatomical, psychological, or clinical features linked to PTTN following endodontic therapy. Three reviewers independently conducted data extraction and quality assessment. An exploratory meta-analysis was performed to estimate the pooled prevalence of PTTN by sex.

Results

Nine studies were included. A predominance of female patients among those with PTTN was observed, with a pooled proportion of 67% (95% CI: 63.3%–70.5%). Psychological comorbidities such as anxiety and depression, previous chronic pain conditions, and endodontic procedures in anatomically high-risk areas particularly mandibular molars were also identified as potential risk factors. Some studies proposed predictive frameworks integrating sensory testing and patient history. However, heterogeneity in study designs and limited quantitative data prevented subgroup analyses.

Conclusions

This review suggests that female sex, psychological vulnerability, and altered sensory modulation may be individual level-risk factors for PTTN following endodontic treatment. These findings reinforce the importance of risk-based clinical decision-making and underscore the need for prospective studies with standardized diagnostic criteria to develop validated predictive models in endodontics.

目的：确定与根管治疗后创伤后三叉神经病变（PTTN）发展相关的患者特异性表型、解剖、心理和临床危险因素。方法：本系统评价遵循PRISMA 2020指南进行，该方案在PROSPERO前瞻性注册（CRD420251071354）。检索在PubMed/MEDLINE和LILACS（通过BVS）中进行，截止到2025年6月。如果研究报告了与根管治疗后PTTN相关的患者水平表型、解剖、心理或临床特征，则该研究是合格的。三名审稿人独立进行数据提取和质量评估。进行探索性荟萃分析，按性别估计PTTN的总患病率。结果：纳入9项研究。观察到PTTN患者中以女性患者为主，合并比例为67% （95% CI: 63.3%-70.5%）。心理合并症，如焦虑和抑郁，既往慢性疼痛状况，以及解剖上高危区域特别是下颌磨牙的根管治疗也被认为是潜在的危险因素。一些研究提出了结合感觉测试和患者病史的预测框架。然而，研究设计的异质性和有限的定量数据阻碍了亚组分析。结论：本综述提示女性性别、心理脆弱性和感觉调节改变可能是根管治疗后PTTN的个体危险因素。这些发现加强了基于风险的临床决策的重要性，并强调了标准化诊断标准的前瞻性研究的必要性，以开发有效的牙髓学预测模型。

Minimally invasive osteotomy and precise root-end resection are key factors in endodontic microsurgery (EMS), particularly in the mandibular molars. Autonomous robotic (ATR) systems facilitate accurate presurgical planning and real-time robot-guided osteotomy and root resection. Integrating the ATR technique with EMS can enhance the accuracy and effectiveness of the treatment. This report presents 2 cases diagnosed with symptomatic apical periodontitis in the mandibular left and right first molar. Cone-beam computed tomography and intraoral scanning data were used to design the surgical plan via planning software. The ATR system guided the robotic arm to autonomously perform precise osteotomy and root resection based on the presurgical plan. At 3–12 months of follow-up, both patients were asymptomatic and radiographic examination revealed complete healing. The ATR technique enabled precise root-end resection despite thick and intact cortical plates, contributing to successful EMS outcomes during the 3- to 12-month follow-up period. This feasibility demonstration warrants further validation in clinical trials with extended follow-ups to assess its potential role in surgical endodontics.

微创截骨和精确根尖切除（RER）是牙髓显微外科手术（EMS）的关键因素，尤其是在下颌磨牙手术中。自主机器人（ATR）系统有助于精确的术前计划和实时机器人引导的截骨和根切除。将ATR技术与EMS技术相结合，可以提高治疗的准确性和有效性。方法：本文报告2例诊断为下颌左、右第一磨牙症状性根尖牙炎的病例。利用锥束计算机断层扫描和口内扫描资料，通过计划软件设计手术方案。ATR系统引导机械臂根据术前计划自主进行精确截骨和根切除。结果：随访3-12个月，两例患者无症状，影像学检查显示完全愈合。结论：尽管皮质板厚且完整，ATR技术仍能实现精确的RER，有助于在3至12个月的随访期间取得成功的EMS结果。这一可行性证明需要在临床试验中进一步验证，并进行长期随访，以评估其在牙髓外科中的潜在作用。

Introduction

This study evaluated differences in intraoral sensitivity to thermal and mechanical stimuli, and pulp sensibility between patients with myofascial orofacial pain (MOP) and healthy controls. We hypothesized that patients would exhibit increased sensitivity to these stimuli.

Methods

A controlled study was performed, including 50 MOP patients and 104 controls aged 18–65. Intraoral and extraoral sensitivities were assessed at various sites using simple quantitative sensory testing (numerical ratings of thermal/mechanical stimuli) and qualitative somatosensory testing (side-to-side differences in sensitivity to touch, cold and pinprick as hyper-, hypo- or normal). Pulp sensibility was evaluated using cold stimuli. Statistical analyses included repeated-measures analysis of variance and Fisher's exact test (α = 0.05).

Results

Patients exhibited significantly higher intraoral hypersensitivity at the buccal gingiva to touch (14%), cold (34%), and pinprick stimuli (36%) compared to controls (0%, 14%, 15%). Similar trends were observed at extraoral sites including the masseter, temporalis, and thenar region. Pulp testing revealed significantly longer pain durations in patients (mean: 5.9 seconds) compared to controls (mean: 3.7 seconds), although pain intensity did not differ significantly. While simple quantitative sensory testing showed no significant group differences, qualitative somatosensory testing effectively identified intraoral and extraoral somatosensory abnormalities.

Conclusions

Patients with MOP exhibited heightened intraoral sensitivity and prolonged pain responses. These findings underscore the diagnostic challenge of distinguishing sensitivity associated with MOP from odontogenic pain, such as pulpitis, which may lead to unnecessary dental procedures. Thorough assessments may help clinicians avoid misdiagnosis and improve outcomes, while longitudinal studies are needed to assess the possibility of clinical consequences.

简介：本研究评估了肌筋膜口面痛（MOP）患者和健康对照者对热、机械刺激的口内敏感性和牙髓敏感性的差异。我们假设患者会对这些刺激表现出更高的敏感性。方法：采用对照研究，包括50例MOP患者和104例年龄在18-65岁的对照组。通过简单的定量感觉测试（sQST，热/机械刺激的数值评分）和定性体感测试（QualST，对触摸、寒冷和针刺的敏感性的侧对侧差异，分别为高、低或正常）评估不同部位的口内和口外敏感性。用冷刺激评价牙髓敏感性。统计分析采用重复测量方差分析和Fisher精确检验（α= 0.05）。结果：与对照组（0%,14%,15%）相比，患者在口腔牙龈对触摸（14%），冷（34%）和针刺刺激（36%）表现出明显更高的口腔内过敏。在口外部位，包括咬肌、颞肌和鱼际区，也观察到类似的趋势。牙髓测试显示，与对照组（平均3.7秒）相比，患者的疼痛持续时间（平均5.9秒）明显更长，尽管疼痛强度没有显著差异。虽然sQST没有显示显着的组间差异，但QualST有效地识别了口内和口外躯体感觉异常。结论：MOP患者表现出较高的口腔内敏感性和延长的疼痛反应。这些发现强调了将MOP与牙源性疼痛（如牙髓炎）相关的敏感性区分开来的诊断挑战，牙髓炎可能导致不必要的牙科手术。彻底的评估可以帮助临床医生避免误诊和改善结果，同时需要纵向研究来评估临床后果的可能性。

Introduction

Epidemiologic studies have reported a relatively high prevalence of asymptomatic apical periodontitis in endodontically treated teeth. Such teeth, when adequately restored and endodontically treated, present a clinical dilemma regarding whether to intervene or follow-up.

The aim of this study was to examine dentists’ clinical decision-making for well-treated endodontically and adequately restored teeth with asymptomatic apical periodontitis, presenting various sizes of simulated apical radiolucencies.

Materials and Methods

Twenty dentists (10 endodontic specialists and 10 prosthodontic specialists) completed a questionnaire containing cases of well-treated asymptomatic teeth, that is, adequately restored and endodontically treated, where some teeth showed normal apical tissues and others presented various sizes of simulated periapical radiolucencies (3 mm, 6 mm, 9 mm, or 12 mm). For each case, participants selected one of 4 treatment options: follow-up, root canal retreatment, endodontic surgery, or extraction.

Results

Both specialty groups unanimously recommended follow-up for teeth without apical radiolucency. When apical radiolucency was present, its size was significantly associated with an active treatment decision, in both univariate and multivariate analyses. Among those who opted for treatment, endodontic surgery was the most frequently selected option, followed by retreatment, while extraction was the least chosen.

Conclusions

This study suggests that dentists’ decision-making regarding asymptomatic, adequately treated teeth with apical periodontitis is influenced by the size of the apical radiolucency. Moreover, there was a general tendency to preserve such teeth and to prefer endodontic surgery over orthograde root canal retreatment.

流行病学研究报告了无症状的根尖牙周炎在根管治疗的牙齿中相对较高的患病率。这样的牙齿，当充分修复和根管治疗，目前的临床困境是关于是否干预或随访。本研究的目的是检查牙医对无症状根尖牙周炎患者的临床决策，这些患者表现出不同大小的模拟根尖放射率。材料和方法：20名牙医（10名牙髓专家和10名修复专家）完成了一份问卷，问卷中包含了治疗良好的无症状牙齿病例，即充分修复和牙髓治疗，其中一些牙齿显示正常的根尖组织，另一些牙齿显示不同大小的模拟根尖周放射率（3mm, 6mm， 9mm或12mm）。对于每个病例，参与者选择四种治疗方案中的一种：随访、根管再治疗、牙髓手术或拔牙。结果：两组一致推荐对无根尖透光牙进行随访。在单变量和多变量分析中，当根尖放射率存在时，其大小与积极的治疗决策显著相关。在选择治疗的人中，牙髓手术是最常见的选择，其次是再治疗，而拔牙是最少的选择。结论：本研究提示牙科医生对无症状的根尖牙周炎患者进行适当治疗的决策受根尖透光率大小的影响。此外，普遍倾向于保留这类牙齿，并倾向于根管手术而不是矫正根管再治疗。

Introduction

This article describes a novel grading system for quantifying potential difficulty in locating and instrumenting root canals where there is evidence of calcification.

Methods

The system is based upon limited field of view cone beam computed tomography which is an essential tool in the diagnosis and treatment of the calcified canal.

Results

The new grading system considers the vertical level at which the canal becomes radiographically evident (coronal, middle or apical), the length of patent canal, and whether the canal is patent at the terminus.

Conclusions

At present there is no classification for canal calcification and no means of categorizing a canal in terms of the potential difficulty/feasibility involved in treating it. It is hoped that this novel grading system will be useful in treatment decision making

本文描述了一种新的分级系统，用于量化有钙化证据的根管定位和器械治疗的潜在困难。该系统是基于有限视场锥束计算机断层扫描（CBCT），这是诊断和治疗钙化管的重要工具。新的分级系统考虑了管在放射学上变得明显的垂直水平（冠状、中位或根尖）、管未通畅的长度以及管在末端是否通畅。目前还没有关于钙化的分类，也没有办法根据治疗钙化的潜在困难/可行性对钙化进行分类。
