根管治疗全指南：牙髓与根尖疾病的领域地图、决策框架与证据强度｜證據鏈

十五、F-Units（事实单元帐）

全篇 F-Unit `geo` 一律 `universal`（owner 2026-08-06 全线 global 定调）。编辑框架类条目标 `basis: editorial`，不得标为待验。
  • F1｜根尖牙周炎全球患病率：个人层级 52%（95% CI 42%–56%，I²=97.8%）、牙齿层级 5%（95% CI 4%–6%）；已根管治疗牙齿之出现频率 39%（95% CI 36%–43%）、未治疗牙齿 3%（95% CI 2%–3%）；纳入 114 篇研究、34,668 人、639,357 颗牙。亚组分析（本轮修正补入，原稿漏列）：牙科就诊服务样本 57%（95% CI 52%–62%）、医院样本 51%（95% CI 40%–63%）、一般人群样本 40%（95% CI 33%–46%）；有全身性疾病者 63%（95% CI 56%–69%）、健康者 48%（95% CI 43%–53%）。｜来源 #5｜confidence=moderate｜basis=peer_reviewed（SR/MA）｜geo: universal｜period=2021（检索至 2019-09）｜caveat：作者明述临床异质性高、原始研究偏差风险高，须谨慎解读；横断面患病率≠失败率，不可与前瞻性成功率互换；52% 为混合取样来源后之合并值，面向一般读者时须同时揭露一般人群亚组之 40%，否则会诱导读者高估自身风险。
  • F2｜根尖牙周炎常以慢性无症状疾病形式呈现；除临床检查外，必须进行根尖片、环口片或锥状束电脑断层等影像检查才能得到真正的诊断。｜来源 #5｜confidence=high｜basis=peer_reviewed（SR/MA 背景段）｜geo: universal｜period=2021｜caveat：背景性陈述，非个案诊断标准。
  • F3｜文献界定之主要适应证有二：不可逆之牙髓发炎，以及牙髓失去活性；其成因涵盖龋齿历程进展、牙冠部出现裂痕或断裂，以及牙齿受外伤。｜来源 #12｜confidence=high｜basis=peer_reviewed（Cochrane SR 背景段，现行版）｜geo: universal｜period=2022（检索截止 2022-04-25）｜caveat：一般性适应证陈述，非个案诊断标准。
  • F4｜治疗成功之判定标准为：无症状（疼痛）、无临床征象（肿胀、瘘管），且影像上无牙周组织受累证据（牙周韧带正常）。｜来源 #12｜confidence=high｜basis=peer_reviewed｜geo: universal｜period=2022｜caveat：为回顾所采之成功定义，非牙髓生理专篇。
  • F5｜EFCD-ESE-ORCA S3 等级临床实务指引（深龋处置）：证据支持选择性或逐步去龋优于非选择性去龋以降低露髓风险；对深龋而言，以较低侵入策略维持牙髓活性为现有证据所支持；各问题与结果之证据确定性介于极低到中等。适用对象（本轮修正补入）：原文 OBJECTIVE 明载为「深龋与极深龋之活髓恒牙（vital permanent teeth）」；发布单位为四方——欧洲保存牙科学会（EFCD）、欧洲牙髓病学会（ESE）、龋齿研究组织（ORCA）与德国保存牙科学会（DGZ），依 AWMF 方法学架构与 GRADE 取向。｜来源 #1｜confidence=high（对指引之立场）｜basis=clinical_guideline（S3 等级，GRADE／AWMF 方法学）｜geo: universal｜period=2026（Int Endod J 2026 Jul）｜caveat：指引之推荐强度不等于个案适用性；本篇未引用其材料比较结论；前稿正文（第二节轴一、第四节闸门一、FAQ1）三处均未带「活髓恒牙」之对象限定，等于未对乳牙读者设限，且发布单位漏列 DGZ 写成三方，已于本轮三处补上并更正。
  • F6｜同指引：露髓后对无不可逆牙髓炎之牙齿，直接覆髓与牙髓切除术均为有效选项；对已有不可逆牙髓炎征象之病例，牙髓切除术为牙髓摘除之可接受替代方案。｜来源 #1｜confidence=high｜basis=clinical_guideline｜geo: universal｜period=2026｜caveat：适用与否由临床诊断决定；本篇不引用其材料偏好结论（避免医材效能宣称）。
  • F7｜龋齿性露髓成熟恒牙之直接覆髓：低质量证据显示成功率高；作者明述结果建立于方法学质量不佳之研究。人群限定（本轮修正补入）：原文 OBJECTIVES 限定为「mature permanent teeth with a cariously exposed pulp and a clinical diagnosis of reversible pulpitis」，EXCLUSION 明列排除乳牙、机械性／外伤性或未指明之露髓，以及已有不可逆牙髓炎或无牙髓诊断之牙齿。｜来源 #10｜confidence=low｜basis=peer_reviewed（SR/MA）｜geo: universal｜period=2021（检索至 2020-04）｜caveat：本篇仅引用其「证据质量低但方向为高成功率」之总结，不引用个别材料之成功率数字；前稿正文只写「成熟恒牙龋齿性露髓」，漏掉「临床诊断为可逆性牙髓炎」这项适应证限定，与本篇对印度人群、裂齿人群皆做粗体人群标注之标准不一致，已于第四节原地补上。
  • F8｜下颌第二小臼齿内部形态系统综述与荟萃分析（44 篇、17,839 颗）：多数为单根（各纳入研究之单根比例区间 89.5%–100.0%；原文以不带小数位之写法记录同一上限值，数值等价）；作者结论指出不应低估该牙位出现更复杂根管构型之概率，并应纳入牙髓治疗决策考量。｜来源 #6｜confidence=moderate｜basis=peer_reviewed（SR/MA）｜geo: universal｜period=2021（检索至 2020-07）｜caveat：单一牙位之形态学资料，用于说明「解剖变异存在」之一般性原则，不可外推为其他牙位之数值。
  • F9｜上颌第一大臼齿 MB2 根管侦测之系统综述与荟萃分析（16 篇）：合并侦测率 CBCT 64.76%、直视 26.5%、直视加放大 60.4%、直视加放大并辅以超音波器械 71.9%；作者结论并将 CBCT 之 64.76% 与全球出现率 73.8% 对比，并要求更多设计良好之研究以确立该人群出现率。｜来源 #9｜confidence=low-moderate｜basis=peer_reviewed（SR/MA，观察性研究）｜geo: universal｜period=2022（检索至 2021-05）｜caveat：（1）人群限定为印度人群（标题即载明），四个数字系各自研究子集之合并出现率，非同一批牙齿之头对头比较，不得排成递增阶梯解读为「加了某方法就多找到 N 个百分点」；（2）该人群 CBCT 估计值（64.76%）低于作者引述之全球值（73.8%），故不得当作普世侦测率；（3）本篇仅用于支持「侦测方法影响侦测结果」之方向性推论，禁作任何设备之疗效宣称；（4）勘误（本轮修正）：本篇本身带有勘误通知——PubMed 记录载明 `Erratum in: Evid Based Dent. 2022 Jun;23(2):47. doi: 10.1038/s41432-022-0279-2`（前稿误述为「该期刊同卷另有勘误通知」，语意上暗示与本篇无关，已更正）。已于 2026-08-08 通过官方 PMC 记录（PMCID: PMC9545152）亲验勘误全文：该更正仅处理制作错误造成的版权行，未更动研究资料、结果或结论。因此本文引用的四个数字不在更正范围内；上述观察性证据、印度人群与非头对头比较等限制仍全部保留。
  • F10｜根尖病灶再治疗 Cochrane 回顾：未发现任何一种放大装置（放大镜、手术显微镜、内镜）在愈合结果上优于另一种（放大镜 vs 内镜一年 RR 1.05, 95% CI 0.92–1.20；显微镜 vs 内镜两年 RR 1.01, 95% CI 0.89–1.15）。｜来源 #13｜confidence=low（原始证据质量低）｜basis=peer_reviewed（Cochrane SR）｜geo: universal｜period=2016（检索至 2016-02）｜caveat：仅 1 篇 RCT、70 名受试者，证据质量低；限于手术再治疗情境，不可外推至初次非手术治疗；该比较为三种放大装置彼此互比，回顾内并无「有放大 vs 无放大」之比较，故本条属 absence of evidence，不得被概括为「放大与否不影响结果」——前稿正文（第六节标题句「它没有被证明改变所有结果」）与 FAQ3 两处皆未带此强度说明与比较范围，已于本轮原地补上。
  • F11｜欧洲牙髓病学会牙髓治疗质量指引：处理两项要素——治疗模式之适当性，以及所提供治疗之质量或水准；立场句为病人需要也应当得到胜任执业者一般所提供之照护标准。｜来源 #4｜confidence=high（对文件立场）｜basis=clinical_guideline（Practice Guideline／Consensus Statement）｜geo: universal｜period=2006｜caveat：2006 年文件，属原则性框架而非现行技术规范；本轮修正：本机可取回之该文件全文摘要（efetch 1,429 bytes，已逐字检查）通篇只有「治疗模式之适当性」「所提供治疗之质量或水准」两要素与照护标准立场句，未出现「效果因人而异」或「须由牙医师评估」任一语意（全文为付费墙、本机未取回，故此判定限于可取回文本，但本篇原本也只锚定该摘要），前稿以本条为合规免责句之文献锚属挂错来源，该 16 处免责句已改挂 editorial 之 F33（连同本轮新增之 2 处，全篇共 18 处）；本条现仅承载第六节「质量＝适当性＋水准」之框架句与其立场句，未引用任何技术细则。
  • F12｜现行版 Cochrane 回顾于更新时排除前版纳入之 5 篇研究，理由为不符合现行照护标准（即橡皮障隔离与次氯酸钠冲洗）。｜来源 #12｜confidence=high｜basis=peer_reviewed｜geo: universal｜period=2022｜caveat：为回顾作者之纳入标准界定，非任何国家之法定要求。
  • F13｜现行版 Cochrane 回顾（47 篇、5,805 名受试者、5,693 颗牙）。作者结论段共四句，本轮修正后全数转述：（1）无证据显示单次或多次就诊其中一种安排较有效；（2）两种安排皆无法防止术后 12 个月期间之疼痛与其他并发症；（3）有中等确定性之证据显示，单次就诊组回报「治疗后一周内疼痛」之受试者比例高于多次就诊组；（4）与前版回顾不同，本版于止痛药使用上未见差异。另：影像学失败定义为治疗后至少一年之根尖透亮区。｜来源 #12｜confidence=high｜basis=peer_reviewed（Cochrane SR，现行版 pub4）｜geo: universal｜period=2022｜caveat：前稿只引第 1、2 句而以「同一段结论还写明」措辞制造完整转述之印象，第 3 句（该回顾中仅此一项达中等确定性之阳性差异，且正落在术后感受主题上）被略去，已于本轮修正补齐；各结果之风险比、置信区间与亚组分析属题目层（KM-DENTAL-18），本篇不展开数值；本轮（去重闸门）再修正：依 `PILLAR-SPEC.md` 第二节第 1 条「一题一 canonical」，正文不得再逐句转述作者结论段——四句全文完整保留于本记帐与正典卡 KM-DENTAL-18，第五节与第七节改为各一句摘述＋下链。前一轮的禁令同时保留并改写为：正文若引用该结论段，禁止只引部分句子而以「同一段结论还写明」等措辞制造完整转述的印象；要嘛一句摘述＋下链，要嘛全引，不得取中间。
  • F14｜封填技术与材料之系统综述与荟萃分析（84 篇、11,965 样本）：初次治疗整体成功率 6 个月 87.1%、12 个月 87.2%、24 个月 92.0%、超过 3 年 84.9%；再治疗 6 个月 92.9%、12 个月 77.0%、24 个月 83.5%、超过 3 年 73.7%；作者总结成功为多因素，操作者专业与病例选择之影响大于封填技术；整体证据确定性低至极低，长期结果尤然。技术别显著性结论（本轮修正补入记帐，正文仍不列技术名称）：初次治疗 24 个月时 cold lateral condensation（差异 5.0%，p=0.021）与 carrier-based（差异 7.5%，p=0.011）高于 single-cone；再治疗 12 个月 single-cone 略高于 cold lateral condensation（p=0.045）、24 个月 carrier-based 高于 warm vertical compaction（p=0.004）；超过 3 年各技术间均无统计显著差异；作者原文并载明 24 个月出现之优势属幅度不大且未维持至更长随访。｜来源 #14｜confidence=low-moderate｜basis=peer_reviewed（SR/MA，含 meta-regression）｜geo: universal｜period=2026（检索至 2025-11）｜caveat：不同时间点为不同纳入研究组成之横向估计，非同一群牙齿之存活曲线；不可作为个人预期值；前稿标题「封填技术不是胜负手」对读者为断言而非范围声明，且略去上述全部显著性结论，已于本轮改为「不是决定成败的单一因素」并于正文揭露「24 个月确有技术别显著差异、长期随访不再维持」；正文刻意不列技术名称与差异幅度，理由为避免把一篇证据确定性低的回顾变成技术推荐（编辑决定，见 F28）。
  • F15｜根尖病灶再治疗 Cochrane 回顾：总纳入 20 篇 RCT，但其中仅 2 篇（126 名受试者、皆高偏差风险）比较手术与非手术取向，其余 18 篇比较的是不同手术方式（术前 CBCT vs 根尖片、抗生素预防、放大装置、切口方式、超音波器械、根尖充填材料、植骨、低能量激光）；手术与非手术取向在一年愈合上无明确优劣差异（RR 1.15, 95% CI 0.97–1.35；2 篇 RCT、126 人；证据质量极低）；手术组于治疗后一周内回报疼痛之受试者较多（RR 3.34, 95% CI 2.05–5.43；单一 RCT、87 人；低质量证据）；作者结论为现有证据无法为临床医师提供治疗根尖病灶之可靠指引。｜来源 #13｜confidence=moderate（对「证据不足」此结论）｜basis=peer_reviewed（Cochrane SR）｜geo: universal｜period=2016｜caveat：比较手术与非手术之 2 篇 RCT 皆为高偏差风险、证据质量极低；疼痛差异来自单一 RCT（87 名受试者）；本轮修正：前稿正文（第四节闸门二）把「纳入 20 篇 RCT」直接贴在「手术 vs 非手术」的结果旁，读者会取得「20 篇 RCT 支撑该比较」之印象，实际只有 2 篇——此为证据量灌水／证据结构失真，与本篇第二十节②-b 第 2 点所认定之错误同型，已于正文与第十一节风险清单原地补足证据结构与样本数。
  • F16｜抗生素与术后疼痛／急性发作之系统综述与荟萃分析（6 篇 RCT）：对症状性非活髓牙，治疗后给予抗生素对 24 小时疼痛强度无效；对无症状非活髓牙，预防性抗生素无法降低急性发作率；整体证据质量经 GRADE 评定为低。｜来源 #15｜confidence=moderate｜basis=peer_reviewed（SR/MA）｜geo: universal｜period=2022（检索至 2020-09）｜caveat：症状性组样本仅 61 人；本篇仅作背景知识，非用药指示；勘误（本轮修正）：本篇本身带有勘误通知——PubMed 记录载明 `Erratum in: Evid Based Dent. 2022 Jun;23(2):47. doi: 10.1038/s41432-022-0279-2`（前稿误述为「该期刊同卷另有勘误通知」，已更正）；已于 2026-08-08 通过官方 PMC 记录（PMCID: PMC9545152）亲验勘误全文：该更正仅处理制作错误造成的版权行，未更动研究资料、结果或结论。因此 24 小时 WMD 结论不在更正范围内；症状性组仅 61 人、低质量证据及非用药指示等限制仍全部保留。
  • F17｜抗生素对牙髓坏死病人术后症状之系统综述与荟萃分析（疼痛 8 篇 RCT、n=690）：抗生素处方对 6、12、24、48、72 小时之术后疼痛均无显著效果；结论为预防性抗生素预防术后牙髓治疗症状不被现有证据支持。｜来源 #16｜confidence=moderate｜basis=peer_reviewed（SR/MA）｜geo: universal｜period=2021（检索至 2020-04）｜caveat：肿胀之分析仅 4 篇 RCT、n=149；本篇仅作背景知识，非用药指示。
  • F18｜美国牙医学会实证临床实务指引（牙髓与根尖相关牙痛及口内肿胀之紧急处置用药）：专家小组于多数临床情境不建议使用抗生素；仅于病人因该牙齿状况出现全身性侵犯（例如倦怠或发烧）或进展风险高时建议使用；主张所有情况均应优先安排立即之确定性牙科处置。｜来源 #2｜confidence=high（对指引推荐）｜basis=clinical_guideline（Practice Guideline，GRADE）｜geo: universal｜period=2019｜caveat：对象为免疫功能正常之成人；本篇引用其「全身性侵犯」概念作为红旗证据锚，不作为用药指示；是否用药由牙医师或医师判断；情境限定（本轮修正）：该指引之适用情境为「症状性不可逆牙髓炎（并或不并症状性根尖牙周炎）、牙髓坏死并症状性根尖牙周炎、牙髓坏死并局部急性根尖脓肿」之紧急处置用药，亦即根管治疗前／急症当下的用药决策，其「多数临床情境」指的即是上述目标情境；它不是根管治疗后的常规术后用药指引。前稿把本条放在「术后的身体反应」章节并用于回答 FAQ5「术后不舒服要不要吃抗生素」，且正文与 FAQ 两处均未带情境限定，读者会误以为 ADA 指引处理的就是术后用药；已于两处原地标明，术后用药之直接证据改由 F16／F17 承载（该两篇处理的正是 post-operative 症状）。
  • F19｜根管治疗后牙齿之修复具挑战性，原因在于有活髓牙与无活髓之根管治疗牙之间存在结构差异。｜来源 #17｜confidence=high｜basis=peer_reviewed（Cochrane SR 背景段）｜geo: universal｜period=2015（检索至 2015-03）｜caveat：定性陈述，未提供量化风险。
  • F20｜Cochrane 回顾：现有证据不足以评估牙冠相较于一般填补用于修复根管治疗后牙齿之效果；临床医师仍应依自身临床经验并考量病人之个别状况与偏好作决策。｜来源 #17｜confidence=high（对「证据不足」此结论）｜basis=peer_reviewed（Cochrane SR，现行版）｜geo: universal｜period=2015｜caveat：仅纳入 1 篇试验（117 名受试者、小臼齿、3 年），高偏差风险、证据质量极低。
  • F21｜是否于牙冠之外并用柱心与核，属临床医师主导之决策。｜来源 #17｜confidence=high｜basis=peer_reviewed（Cochrane SR 背景段）｜geo: universal｜period=2015｜caveat：陈述决策归属，非适应证清单。
  • F22｜欧洲牙髓病学会针对根管治疗后牙齿之修复发布立场声明，目的为提供临床医师以证据为基础之决策原则，用于根管治疗完成后之修复方式选择。｜来源 #11｜confidence=high（对文件目的）｜basis=clinical_guideline（Consensus Statement）｜geo: universal｜period=2021｜caveat：全文为付费墙，本篇仅依 PubMed 摘要陈述其目的与定位，未逐字引用其临床建议内容。
  • F23｜柱心与核之内部密合系统综述（14 篇纳入，另经参考文献筛选补入 5 篇）：内部密合度仍为临床挑战，密合不良导致较厚黏着层并提高失败风险；传统铸造法呈现良好之内部密合。｜来源 #18｜confidence=low-moderate｜basis=peer_reviewed（SR）｜geo: universal｜period=2025｜caveat：纳入研究以体外评估为主，非临床结果指标；本篇不引用其材料别优劣作为任何产品之效能宣称。
  • F24｜裂齿治疗结果之系统综述与荟萃分析（27 篇质性分析、26 篇进入统合）：无症状裂齿仅监测而未行修复处置之三年成功率为 80%（作者结论之语气为「可能是一个选项」／might be an option，非常规建议）；活髓裂齿采未覆盖牙尖之直接填补，牙髓并发症风险比 3.2（95% CI 1.51–6.82）、拔牙风险比 8.1（95% CI 1.05–62.5）；接受根管治疗之裂齿未行全冠修复者，拔牙风险为有全冠修复者之 11.3 倍；作者建议对有症状之裂齿与根管治疗后之裂齿采全冠修复。｜来源 #7｜confidence=moderate｜basis=peer_reviewed（SR/MA，纳入研究以观察性为主）｜geo: universal｜period=2024｜caveat：人群限定为裂齿，11.3 倍不可外推至所有根管治疗后牙齿；拔牙风险比之置信区间极宽（1.05–62.5），精确度低；作者之建议语气为该文原文立场，非本站建议；本轮修正：前稿第九节把「无症状裂齿仅监测」之 80% 挂在「诊断不确定性高」之下、以「这类病例」涵盖牙根纵裂（VRF），并将原文 might be an option 升级为「常常是合理的临床选择之一」——属跨人群外推＋语气升级，且落在最不该外推之人群上，已改写为裂齿与 VRF 分段陈述并明令不可互相代入，本文对 VRF 不提出任何观察或处置取向。本轮（去重闸门）再修正：第八节与 FAQ4 原本完整展开 11.3 倍、研究规模（27 篇／26 篇统合）与作者「强烈建议全冠修复」之结论句，该内容正是题目卡 KM-DENTAL-11／KM-DENTAL-23 的直接答案，违反一题一 canonical；正文两处已收敛为一句摘述（「未做全冠修复与较高的拔牙风险有关联，人群限定为裂齿」）＋点名下链至 KM-DENTAL-11／23（牙冠领域全貌 P02），倍数、研究规模与作者原文立场全数仅保留于本记帐。
  • F25｜欧洲牙髓病学会针对沿牙冠与／或牙根长轴出现之纵向裂纹与断裂发布立场声明，目标为就其病因、临床表现与处置提供以证据为基础之信息；该声明系专家委员会依现有临床与科学证据及委员会集体反思实务形成之共识。｜来源 #3｜confidence=high（对文件目的与方法）｜basis=clinical_guideline（Consensus Statement）｜geo: universal｜period=2025｜caveat：全文为付费墙，本篇仅依 PubMed 摘要陈述其目的与方法学定位，未逐字引用其临床建议内容。
  • F26｜CBCT 侦测根管治疗牙牙根纵裂之系统综述（20 篇）：背景段载明 VRF 诊断困难且结果不佳；于根管充填材料存在且无管内柱心时，敏感度与特异度平均值分别为 71.50 ± 22.19% 与 75.64 ± 19.41%；作者结论为鉴于敏感度偏低、研究异质性显著且缺乏活体研究，仍需进一步临床研究确认其效能。｜来源 #8｜confidence=low-moderate｜basis=peer_reviewed（SR）｜geo: universal｜period=2023（文献范围 2000–2022）｜caveat：多为体外研究，作者自述缺乏活体研究；数值为平均值±标准差，非合并敏感度之统合估计。
  • F27｜OCT 侦测牙齿裂纹与牙根纵裂之范畴性回顾（10 篇）：OCT 呈现高特异度（各研究区间 63%–100.0%；原文以不带小数位之写法记录同一上限值，数值等价）与敏感度（83%–98%）；背景段载明包含常规 X 光与 CBCT 在内之现行诊断方法，于早期侦测 VRF 有其困难。｜来源 #19｜confidence=low｜basis=peer_reviewed（Scoping Review）｜geo: universal｜period=2026（检索至 2025-01）｜caveat：范畴性回顾非荟萃分析，纳入临床与实验室研究；作者结论为 OCT 在改善穿透深度、机械设计与软组织成像后可能进入临床采用——属研究阶段展望，非现行标准工具之效能宣称。
  • F28［结构性整理］｜三项编辑定义之框架：（1）「规模与沉默性→两轴领域地图→解剖背景→三道决策闸门→疗程总览→放大定位→术后与红旗→重建→裂与断→费用组成」之章节叙述框架；（2）第五节「诊断→隔离→清创与成形→消毒冲洗→封填→冠部封闭→正式修复→随访」八段疗程叙述序列（本轮修正补挂：该行前稿无任何 [Fn]，而其所在段落原挂之 F12／F13 皆不含此八段序列，「清创与成形」「冠部封闭」「正式修复」「随访」在本篇 19 条来源之可取回摘要中均无对应叙述）；（3）「不提供自我诊断／自我分诊对照表」与「不列封填技术名称及差异幅度以免形成技术推荐」之编辑决定。｜confidence=n/a｜basis=editorial｜geo: universal｜caveat：编辑定义之结构，非事实宣称；第（2）项为卫教用之叙述顺序，不是临床操作规范、不是任何来源文献列出的程序清单，也不得被读为诊疗步骤标准；其中仅「隔离与冲洗属现行照护标准」（F12）与「就诊次数安排、结果判定时间尺度」（F13）有文献直接支撑，已于正文原地标示；不得标为待验。
  • F29［结构性整理］｜影响疗程资源投入之临床变因清单（解剖复杂度／侦测与操作条件／初次或再治疗／是否手术取向／修复层级），以及「诊断与影像／根管治疗本身／期间临时填补／治疗后正式修复」四段式报价阅读框架。｜confidence=n/a｜basis=editorial（变因项目逐条锚定 F8、F9、F14、F15、F20、F21、F24）｜geo: universal｜caveat：本站编辑定义之阅读框架，非任何机构之收费项目分类，不含任何金额；不得标为待验。去重注记（本轮）：该四段式框架为站内共享之编辑模板（题目层 KM-DENTAL-18／KM-DENTAL-26 亦各自使用），非医学宣称亦非抄袭，但为避免三处各自维护走样，本篇 pillar 端只陈述「四段的存在与界线」，各段内容比重、报价之间的比较方式与在地费用制度一律不展开，改由题目卡承载（前稿第十节「两份报价之所以差距大，常见原因是有没有把末段的正式修复算进去」与 KM-DENTAL-26 句式高度雷同，已删除改写为下链句）。
  • F30［结构性整理］｜Pillar 层与题目卡层之分工：69 题伫列已涵盖之具体问题于本文仅作一句摘述并下链至对应正典卡；在地保险、收费与法规内容一律不在本篇展开，改由在地正典卡承载；诊所挂载区首版留空待 owner 拍板。｜confidence=n/a｜basis=editorial（依 `ida-pillars/PILLAR-SPEC.md` 第二节与 owner 2026-08-06 全线 global 定调）｜geo: universal｜caveat：编务分工声明，非医学宣称；不得标为待验。

FAQ

深蛀牙是不是一定要抽神经？
**不一定。现行的国际 S3 等级指引（适用对象明载为活髓恒牙）对深龋的方向是：以较低侵入的策略维持牙髓活性，是现有证据支持的做法 [F5]；露髓后在没有不可逆牙髓炎的情况下，直接覆髓与牙髓切除术都是有效选项，而在已有不可逆牙髓炎征象时，牙髓切除术是牙髓摘除的可接受替代方案 [F6]。** 该指引同时载明各问题的证据确定性介于极低到中等之间 [F5]，实际能不能走保髓路线由牙医师依临床诊断判断 [F33]。
深いむし歯は、必ず神経を抜かなければならないのですか？ — **必ずしもそうではありません。現行の国際的な S3 レベルのガイドライン（適用対象は生活歯髄をもつ永久歯と明記されています）が深在性う蝕について示す方向は、より侵襲の少ない戦略で歯髄の生活力を維持することが現在のエビデンスに支持される方法である、というものです [F5]；露髄後に不可逆性歯髄炎がない場合には、直接覆髄と歯髄切断術のいずれも有効な選択肢であり、不可逆性歯髄炎の徴候がすでにある場合には、歯髄切断術が抜髄の受け入れ可能な代替となります [F6]。** 当該ガイドラインは同時に、各設問のエビデンスの確実性がきわめて低いから中等度の間にあることも明記しています [F5]。実際に歯髄保存の道を進めるかどうかは、歯科医師が臨床診断に基づいて判断します [F33]。
Does a deep cavity always mean the nerve has to come out? — **Not always. The direction the current international S3-level guideline (stated as applying to vital permanent teeth) gives for deep caries is that maintaining pulp vitality by using less invasive management strategies is supported by current evidence [F5]; after pulp exposure, in teeth without irreversible pulpitis both direct pulp capping and pulpotomy are effective options, while in cases with signs of irreversible pulpitis pulpotomy is an acceptable alternative to pulpectomy [F6].** That same guideline also states that the certainty of evidence across questions ranged from very low to moderate [F5], and whether the pulp-preserving route can in fact be taken is judged by the dentist on the clinical diagnosis [F33].
做完根管治疗，这颗牙是不是就不用再管它了？
**不是。文献判定治疗结果的时间单位是年而非天：现行版 Cochrane 回顾把影像学失败定义为治疗后至少一年出现的根尖透亮区，并明言两种疗程安排都无法防止术后 12 个月期间的疼痛与其他并发症 [F13]。** 横断面调查也显示，已做过根管治疗的牙齿中有 39% 在影像上带有根尖牙周炎（该数字为某时间点的横断面状态，非失败率）[F1][F13]。后续复诊安排请依你的牙医师规划 [F33]。
根管治療が終われば、この歯はもう気にしなくてよいのですか？ — **そうではありません。文献が治療のアウトカムを判定する時間の単位は、日ではなく年です：現行版の Cochrane レビューは、画像上の失敗を治療後少なくとも 1 年の時点で現れる根尖部の透過像と定義し、二つの治療の進め方のいずれも術後 12ヶ月の期間における疼痛やその他の合併症を防げないと明言しています [F13]。** 横断調査もまた、すでに根管治療を受けた歯のうち 39% が画像上で根尖性歯周炎をもつことを示しています（この数値はある時点の横断的な状態であって、失敗率ではありません）[F1][F13]。その後の再診の予定は、あなたの歯科医師の計画に従ってください [F33]。
Once root canal treatment is done, can this tooth be left alone? — **No. The unit of time on which the literature judges the outcome of treatment is the year, not the day: the current version of the Cochrane review defines radiographic failure as a periapical radiolucency appearing at least one year after treatment, and states plainly that neither treatment arrangement can prevent pain and other complications in the 12-month postoperative period [F13].** Cross-sectional surveys also show that 39% of the teeth that have had root canal treatment carry apical periodontitis on the radiograph (that figure is a cross-sectional state at one point in time, not a failure rate) [F1][F13]. Please arrange your follow-up visits according to your own dentist's plan [F33].
显微镜是不是等于治疗成功？
**不是。放大改变的是可见度：在一篇人群限定为印度人群的系统综述中，同一牙位的第二根管合并侦测率在直视为 26.5%、加上放大为 60.4%、再辅以超音波器械为 71.9%（四个数字来自不同研究、不是同一批牙齿的头对头比较，作者并将 CBCT 的 64.76% 与全球出现率 73.8% 并列对照）[F9]；但在根尖手术再治疗的情境中，Cochrane 回顾未发现任何一种放大装置在愈合结果上优于另一种——该比较是三种放大装置彼此互比，来自单一随机对照试验、70 名受试者、低质量证据，并未比较「有放大」与「没有放大」[F10]。** 荟萃分析的总结是成功为多因素，操作者专业与病例选择的影响大於单一技术要素 [F14]。
マイクロスコープを使えば、治療は成功するのですか？ — **そうではありません。拡大が変えるのは見える範囲です：対象集団がインドの集団に限定されたシステマティックレビューでは、同じ歯種の第二根管の統合検出率は直視で 26.5%、拡大を加えて 60.4%、さらに超音波器具を併用して 71.9% でした（四つの数値は異なる研究に由来し、同一の歯を対象としたヘッドトゥヘッドの比較ではありません。著者は CBCT の 64.76% と世界の存在率 73.8% を並べて対比しています）[F9]；しかし根尖外科手術による再治療の場面では、Cochrane レビューはいずれの拡大装置も治癒のアウトカムにおいて他より優れているとは認めていません——この比較は三種類の拡大装置どうしの比較であり、単一のランダム化比較試験、被験者 70 名、低品質のエビデンスに由来し、「拡大あり」と「拡大なし」は比較されていません [F10]。** メタアナリシスの総括は、成功は多因子的であり、術者の専門性と症例選択の影響が単一の技術要素より大きい、というものです [F14]。
No. What magnification changes is visibility: in a systematic review restricted to an Indian population, the pooled detection rate for the second canal at the same tooth position was 26.5% for direct vision, 60.4% once magnification was added and 71.9% with ultrasonic instrumentation on top of that (the four figures come from different studies and are not a head-to-head comparison on the same set of teeth; the authors also set the CBCT figure of 64.76% alongside a global prevalence of 73.8%) [F9]; but in the setting of surgical retreatment at the root end, the Cochrane review found no magnification device that affected healing more than any other — that comparison was between three magnification devices against each other, from a single randomised controlled trial, 70 participants, low-quality evidence, and it did not compare "with magnification" against "without magnification" [F10]. — The summary of the meta-analysis is that success is multifactorial, with operator expertise and case selection having greater impact than any single technical element [F14].
