• F4｜同一立场声明诊断段：咬合测试目的为重现患者症状，特别是咬硬物或咬紧时的突发敏感和锐痛，该痛在压力释放时停止；非活髓牙可有根尖周炎症状和／或征象及边缘嵴断裂证据；裂齿牙周探测小于 6 mm，垂直根裂探测深度更深｜来源 #1｜confidence=verified｜basis=clinical_guideline（同 F3 来源）｜period=2025；检索日 2026-08-06｜geo: universal｜取回方式：同 F3（PMC 全文），本行不加 PMID 前缀｜span:「The aim of the bite test is to reproduce the patient's symptoms, particularly sudden sensitivity and sharp pain when biting hard foods and/or clenching, which ceases upon the release of pressure.」「In non‐vital teeth, there may be symptoms and/or signs of apical periodontitis (AP) as well as evidence of marginal ridge fractures.」「Narrow periodontal probing of less than 6 mm is associated with CT, whereas periodontal probing depths of VRF are deeper」｜caveat：咬合测试是医师使用的检查方法，本卡不描述操作，也不建议自行尝试；探测深度由医师量测，患者不能自行判断；本栏与 F3 临床特征表对“压力释放”的方向并不完全相同（此处为压力释放时停止，F3 表为咀嚼时或压力释放时疼痛），本卡两者并列、不择一、不代为调和。
• F5｜同一立场声明病因与通则段：裂齿病因为多因素，涉及咬合干扰、牙齿形态、既往修复治疗、硬食造成的咀嚼负荷增加和／或异常功能习惯；潜在因素表另列修复处置产生应力、修复材料热膨胀、收缩和腐蚀；通则记载过度咬合力量在裂齿、裂开的牙和垂直根裂病因中的影响不容低估，并建议有适应证时给予管理异常功能习惯建议、处理咬合干扰形成较协调咬合方案以限制裂痕延伸，可能需多学科途径｜来源 #1｜confidence=verified｜basis=clinical_guideline（同 F3 来源）｜period=2025；检索日 2026-08-06｜geo: universal｜取回方式：同 F3（PMC 全文），本行不加 PMID 前缀｜span:「CT aetiology is multifactorial, involving occlusal interferences, tooth morphology, previous operative dentistry, increased masticatory loading due to hard food diets, and/or parafunctional habits」「The impact of excessive occlusal forces cannot be overemphasised in the aetiology of CT, ST, and VRF.」「When indicated, patients should be given advice on managing parafunctional habits. Occlusal interferences should also be managed to create a more harmonious occlusal scheme to limit extension of CT; this may require a multi‐disciplinary approach.」｜caveat：病因列举为共识层级描述，并非量化因果强度；“应处理咬合干扰”是给临床医师、且以有适应证为前提的建议，不能读为对任何个人的处置指示。
• F6｜同一立场声明影像段：早期裂齿在根尖片上可能没有明显裂痕和／或病理征象；Hilton 等人报告只有 2% 活髓裂齿在 X 光片上有裂痕证据；CBCT 检出裂痕并不可靠，但可能显示与裂齿有关的细微牙槽嵴骨丧失｜来源 #1｜confidence=verified｜basis=clinical_guideline（同 F3 来源）｜period=2025；检索日 2026-08-06｜geo: universal｜取回方式：同 F3（PMC 全文），本行不加 PMID 前缀｜span:「Hilton et al. ( 2017 ) reported that only 2% of CTs with vital pulps had evidence of a crack on a radiograph.」「CBCT is not predictable in detecting cracks but may reveal subtle crestal bone loss associated with CT」｜caveat：2% 是该声明转引的原始执业型观察研究数字；本卡仅以其支持“影像正常不能排除裂齿”，未主张任何影像检查应做或不应做——是否加做影像由医师按适应证和辐射考量决定。
• F7｜同一立场声明处置与预后段：无症状未处置裂齿能稳定多久仍不清楚，因现有研究仅追踪 1 至 3 年；未处置高风险裂齿可进展为牙尖断裂或裂开的牙（如末端（小）臼齿远中边缘嵴、大范围修复牙、孤立或末端牙、长期异常功能习惯者），该类情形有处置适应证；裂开的牙预后不佳，应考虑及时拔除以减少急性症状发展并限制骨丧失；根管治疗后裂齿的负向预后因素包括多处裂痕、裂痕伸入牙根、位于牙弓末端、术前根尖周炎和根管内桩，牙周探测 5 mm 以上与较低存留率有关；没有明确证据指出何种修复途径最佳，分阶段处理虽可观察牙髓状态，但牙髓活力可因微渗漏、黏固剂劣化或后续治疗受损；结论记载覆盖牙尖修复的活髓或根管治疗后裂齿结果令人鼓舞，早期处理、覆盖牙尖修复及没有非牙髓来源的深牙周探测深度可提高存留率｜来源 #1｜confidence=verified｜basis=clinical_guideline（同 F3 来源）｜period=2025；检索日 2026-08-06｜geo: universal｜取回方式：同 F3（PMC 全文），本行不加 PMID 前缀｜span:「It remains unclear for how long asymptomatic, untreated CT can remain stable and without further crack propagation, as current studies have only monitored cracks for 1–3 years」「ST has an unfavourable prognosis, and timely extraction should be considered to minimise the development of acute symptoms and limit bone loss.」「A 5 + mm periodontal probing is associated with reduced survival rates」「Current evidence suggests encouraging outcomes for vital as well as endodontically treated CT restored with cuspal coverage restorations. Early management, cuspal coverage restorations, and absence of deep periodontal probing depth of non‐endodontic origin increase the survival rate of CT management.」「While interim treatment allows pulpal healing and confirms initial diagnosis prior to definitive restoration, pulp vitality may be compromised due to microleakage, cement breakdown, and/or further definitive treatment」｜caveat：“令人鼓舞”是声明对整体证据的措辞，不是疗效保证；本卡不引其转引的任何存留率百分比；预后因素为人群层级关联，不能预测个别牙齿结果；处置决策须由牙医师按个别条件判断。
• F8｜执业型观察研究（美国全国牙科执业研究网络；209 位执业者纳入 2,975 颗至少有一条可见外部裂痕的单颗活髓后牙；用广义估计方程取得独立优势比）：与裂齿有症状正相关的特征为咬紧、磨牙或压紧牙者（OR 1.30，95% CI 1.12 至 1.50）、臼齿（1.58，1.30 至 1.92）、穿透牙釉质磨耗面（1.22，1.01 至 1.40）、龋坏病灶（1.31，1.07 至 1.60）、牙远中面的裂痕（1.31，1.13 至 1.52）和阻断透照光裂痕（1.31，1.09 至 1.57）；染色裂痕与症状负相关（0.68，0.55 至 0.84）｜来源 #2｜confidence=verified｜basis=peer_reviewed（PMID 28160942，观察性研究）｜period=2017；检索日 2026-08-06｜geo: universal｜span:「they enrolled 2,975 cracked teeth from 209 practitioners」「Characteristics positively associated with cracked tooth symptoms, after adjusting for demographics, included patients who clenched, ground, or pressed their teeth together (OR, 1.30; 95% confidence interval [CI], 1.12-1.50), molars (OR, 1.58; 95% CI, 1.30-1.92), teeth with a wear facet through enamel (OR, 1.22; 95% CI, 1.01-1.40), carious lesions (OR, 1.31; 95% CI, 1.07-1.60), cracks that were on the distal surface of the tooth (OR, 1.31; 95% CI, 1.13-1.52), and cracks that blocked transilluminated light (OR, 1.31, 95% CI, 1.09-1.57)」「Teeth with stained cracks were negatively associated with having cracked tooth symptoms (OR, 0.68; 95% CI, 0.55-0.84)」｜caveat：便利抽样观察研究、非随机试验；优势比为关联而非因果，且只适用于已有可见裂痕的牙，不能外推成“有磨牙习惯就会咬痛”；本篇牙数（2,975）与 F3 转引研究牙数（2858）口径不同，本卡分别照录，不合并不换算。
• F9｜同一研究开放取用全文引言：不完全齿裂的诊断一直完全依据牙齿症状学——咀嚼或咬合时局部痛、无法解释的冷敏感及压力释放时痛；结果段记录 1,364 颗（46%）牙有症状｜来源 #2｜confidence=verified｜basis=peer_reviewed（观察性研究全文，同来源 #2）｜period=2017；检索日 2026-08-06｜geo: universal｜取回方式（可复现）：`efetch db=pmc id=5376224 rettype=full retmode=xml`（PMC 开放取用全文），去标签后逐字比对；本栏 span 来自全文而非 PubMed 摘要，故不加 PMID 前缀｜span:「The diagnosis of incomplete tooth fracture has been based exclusively on tooth symptomatology: localized pain during chewing or biting, unexplained sensitivity to cold, and pain on release of pressure」「1,364 (46%) teeth were symptomatic」｜caveat：该句是研究引言对既往文献的综述性描述（原文附多笔引注），不是该研究本身的测量结果；本卡仅以其证明文献确实记录过“压力释放时痛”，不作为诊断标准；本条同时修正 KM-DENTAL-33 卡 F25 的“未取得可引用来源”记述，该卡应在取得本句后回头更新证据缺口声明。
• F10｜同一执业网络一年追踪研究（209 位牙医师纳入 2858 位受试者，各有一颗至少一条可见外部裂痕的单颗活髓后牙；1850 颗牙一年后仍未处置并形成分析人群）：32% 疼痛症状变化，减少为增加的两倍（23% 对 10%）；冷痛变化多于咬合痛和自发痛增加的总和，咬合痛增加者 2%、自发痛增加者 2%、仅 6% 裂痕数增加；结论为未受治疗裂齿一年后未显示以症状增加或裂痕数增加衡量的有意义进展｜来源 #3｜confidence=verified｜basis=peer_reviewed（PMID 31899264，观察性追踪研究）｜period=2020（追踪一年）；检索日 2026-08-06｜geo: universal｜span:「209 National Dental Practice-Based Research Network dentists enrolled a convenience sample of 2858 subjects, each with a single, vital posterior tooth with at least one observed external crack; 1850 teeth remained untreated after one year of follow-up and were the cohort for analyses」「Changes in pain symptoms were observed in 32% of patients; decreases were twice as common as increases (23% vs. 10%)」「2% had increases in biting pain and 2% in spontaneous pain. Only 6% had an increase in the number of cracks」「Cracked teeth that have not received treatment one year after baseline do not show meaningful progression as measured by increased symptoms or number of cracks during follow-up」｜caveat：该人群是牙医师检查后多数建议监测的牙，不是未就医人群，不得读为“不看牙也没关系”；追踪仅一年，须与 F7“仅追踪 1 至 3 年、长期稳定性不明”并读。
• F11｜执业研究网络三年观察结果回顾文章（回顾 2017 至 2022 年发表的 8 篇论文）：牙裂很常见，但三年内仅少数会断裂（3%）或出现裂痕进展（12%）；引导临床医师决定处置的特征包括活动性龋、咬合痛，以及影响程度较低的探针可检出裂痕、与修复体相连、阻断透照光；受处置牙（36%）中少数（14%）需再处置｜来源 #4｜confidence=verified｜basis=peer_reviewed（PMID 36690539，回顾文章）｜period=2023；检索日 2026-08-06｜geo: universal｜span:「few will fracture (3%) or show crack progression in 3 years (12%)」「Characteristics that guide the clinician to treatment include active caries, biting pain, and to a lesser degree, having a crack detectable with an explorer, connecting with a restoration, or blocking transilluminated light」｜caveat：观察性研究网络数据、非随机试验；比例属该网络人群，不能外推为个别牙齿风险；原文把咬合痛列为引导处置特征之一，本卡据此明确反对将 3%／12% 读成“可以不理”；与 KM-DENTAL-33 卡 F14 同锚。
• F12｜欧洲牙髓病学会为 S3 指引委托的系统性综述（29 篇出版品中纳入 28 项研究）：诊断牙髓炎的有效性偏低，因诊断测试准确度和可重复性的科学证据有限；核心问题为临床条件下缺少可靠参考标准；基于有限证据，目前较有希望的方法为结合不同临床测试与症状｜来源 #5｜confidence=verified｜basis=peer_reviewed（PMID 35536159，系统性综述）｜period=2022（检索至 2022-01-21）；版本时效沿用 KM-DENTAL-33 查核（2026-08-06 以 `pulp[Title] AND diagnos*[Title] AND systematic review[pt]` 按日期排序检索，2022 年后未取得同题更新版）｜geo: universal｜span:「The effectiveness of diagnosing pulpitis is low due to limited scientific evidence regarding the accuracy and reproducibility of diagnostic tests」「The core problem in pulp diagnostics is that a reliable reference standard is lacking under clinical conditions」「the most promising current approach seems to define a combination of different clinical tests and symptoms」｜caveat：该综述检视牙髓诊断测试效能，不是咬合痛鉴别诊断；本卡以其为“症状单独不足以下结论”的一般性依据，不得读为临床诊断无用，也不得读为鼓励自我判断；与 KM-DENTAL-33 卡 F3 同锚。
• F13｜Cochrane 系统性综述（成人症状性根尖周炎和急性根尖脓肿的全身性抗生素；3 项试验、134 位受试者）：背景载明二者为牙痛常见原因，来自发炎或坏死牙髓或无牙髓根管系统感染；临床指引建议初始治疗应以局部操作移除炎症或感染来源，全身性抗生素目前仅建议用于有感染扩散迹象（蜂窝织炎、淋巴结受累、弥漫性肿胀）或全身性影响（发烧、倦怠）的情形｜来源 #6｜confidence=verified｜basis=peer_reviewed（PMID 38712714，Cochrane 系统性综述 CD010136.pub4）｜period=2024（检索至 2022-11）；版本时效沿用 KM-DENTAL-33 查核（`CD010136` 回传 3 笔，本篇 pub4 为现行版，pubtype 无 Retracted Publication）；本卡于 2026-08-06 另以 esummary 复查 pubtype，无撤回标记｜geo: universal｜span:「Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system」「Clinical guidelines recommend that the first-line treatment for these conditions should be removal of the source of inflammation or infection by local operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise)」｜caveat：该综述比较的药名一律不引、不建议、不提供剂量；“感染扩散迹象”和“全身性影响”是综述转述临床指引的医师判断标准，本卡用作患者回报观察项，不是自我诊断标准；与 KM-DENTAL-33／05 同锚。

• F22｜系统性综述与统合分析（咬合面降低能否减轻根管治疗后疼痛；检索至 2019-08，仅纳入随机安慰剂对照试验；6 项试验、344 位受试者；以随机效应反变异数法计算标准化平均差）：12、24、48 小时疼痛强度较安慰剂未达显著差异；72 小时时介入组比安慰剂组有显著更多疼痛减轻（SMD −1.07；95% CI −1.81 至 −0.32；P = .005）；作者结论为咬合面降低在术后两天内控制疼痛未获支持，但第三天有正面影响｜来源 #15｜confidence=verified｜basis=peer_reviewed（PMID 31880822，系统性综述与统合分析）｜period=2020（检索至 2019-08）；版本时效已查（同 F21 检索，本篇较 F21 旧，本卡两者并列并标明结论方向不完全一致）｜geo: universal｜span:「In total, six randomised controlled trials including 344 participants were included」「However, at 72 hours, patients received intervention showed significant more pain reduction than placebo groups (SMD = -1.07; 95% CI = -1.81, -0.32; P = .005)」「Based on this meta-analysis, the efficacy of occlusal reduction in post-endodontic pain control for up to 2 days is not supported」｜caveat：与 F21 结论方向不完全一致（本篇在 72 小时观察到差异，F21 未涵盖该时点且整体未显示差异），本卡两者并列、不择一、不代为调和；同样限于根管治疗情境。
• F23｜临床指引（咬合异常感觉；以 PubMed、Cochrane Library、Google Scholar 与相关期刊档案文献检索为基础，依证据等级加权形成专家共识，纳入 77 篇文章）：咬合异常感觉独立于咬合而存在，是适应不良信号处理的结果；重点应放在患者教育、咨询、去焦点化、认知行为治疗、支持性药物治疗及若干非特异措施；必须避免不可逆、特别是纯牙科取向治疗｜来源 #16｜confidence=verified｜basis=clinical_guideline（PMID 32080883，Practice Guideline）｜period=2020（检索 2018）；版本时效已查——2026-08-06 以 `occlusal dysesthesia[tiab]` 限 2021 年后检索，取得 2026 年范围界定综述（F24），本卡两者并列且结论方向一致｜geo: universal｜span:「Occlusal dysesthesia exists independently of the occlusion.
