  • F2|疼痛盛行率:治療前 81%(標準差 28)、術後 24 小時 40%(標準差 24)、術後一週 11%(標準差 14);疼痛強度(0 至 100 分量表)依序為 54(標準差 24)、24(標準差 12)、5(標準差 5);該回顧納入 72 篇研究進行統合分析。|來源 #1|confidence=moderate|basis=peer_reviewed(系統性回顧與統合分析)|period=2011(本卡 2026-08-06 檢索未見取代本篇之新版一般性盛行率回顧)|geo: universal|caveat:括號內為標準差非信賴區間;為群體平均,個別差異大;本卡不引用該篇的補充麻醉數值(原文標示格式與百分比不同)。
  • F3|同篇結論:治療前的根管相關疼痛盛行率高,但在治療後一天內中等幅度下降,並在 7 天內降至極低程度;強度亦同向下降。|來源 #1|confidence=moderate|basis=peer_reviewed|period=2011|geo: universal|caveat:族群層級的方向性結論,不得轉述為對個人的天數承諾
  • F4|現行版 Cochrane 回顧的結果設定:主要結果為拔牙與治療後至少一年的影像學失敗(根尖透亮區);次要結果為術後與封填後疼痛、腫脹或急性發作、止痛藥使用、至少一個月後是否出現瘻管;封填後 72 小時內疼痛比例兩組未測到差異(風險比 0.97,95% 信賴區間 0.81 至 1.16;I²=70%;12 篇研究、1329 顆牙;低確定性)、封填後一週疼痛亦未測到差異(風險比 1.05,95% 信賴區間 0.67 至 1.67;9 篇研究、1139 顆牙;極低確定性)。|來源 #2|confidence=high(對結果設定)/moderate(對數值)|basis=peer_reviewed(Cochrane SR/MA,現行版 pub4)|period=2022(檢索截止 2022-04-25;2026-08-06 於 PubMed 檢索 CD005296 僅見 2007/2016/2022 三版,未見 pub5)|geo: universal|caveat:本卡引用其時間點設定與無差異結果,不引申為療效比較結論。
  • F5|一週內回報疼痛之受試者比例,單次就診組較高:風險比 1.55(95% 信賴區間 1.14 至 2.09;I²=18%;5 篇研究、638 顆牙;中等確定性);活髓牙次群組風險比 2.16(2 篇研究、316 顆牙)。|來源 #2|confidence=moderate|basis=peer_reviewed|period=2022|geo: universal|caveat:本條的完整討論歸 KM-DENTAL-18,本卡僅摘述並指向該卡;與 F10 傘狀回顧的結論方向不完全一致,本卡兩者並陳。
  • F6|腫脹或急性發作發生率兩組未測到差異(風險比 0.56,95% 信賴區間 0.16 至 1.92;I²=0%;6 篇研究、605 顆牙;極低確定性);止痛藥使用亦未測到差異(風險比 1.25,95% 信賴區間 0.75 至 2.09;I²=36%;6 篇研究、540 顆牙;極低確定性)。|來源 #2|confidence=low(原文自評極低確定性)|basis=peer_reviewed|period=2022|geo: universal|caveat:極低確定性證據,僅用於說明「這些是被追蹤的事件」與「不是靠選次數控制的」,不得反推任何處置建議;止痛藥一條僅陳述其為結果指標,本卡不給用藥建議。
  • F7|同篇作者結論:如同前兩版,目前沒有證據顯示單次或多次就診其中一種更有效;兩種安排都無法免除術後 12 個月期間的疼痛與其他併發症。|來源 #2|confidence=high|basis=peer_reviewed|period=2022|geo: universal|caveat:此為「無差異」與「無法免除」的陳述,非任一安排較優之證據。
  • F8|前瞻性臨床研究:270 位接受單次根管治療的病人,於術後 4、8、16、24、48、72 小時以 0 至 10 公分視覺類比量表記錄疼痛與止痛藥使用;平均術後疼痛 2.58(標準差 2.80);作者結論為術前疼痛的存在是影響術後疼痛盛行率的主要變項。|來源 #3|confidence=low|basis=peer_reviewed(單一中心前瞻性研究)|period=2016|geo: universal|caveat:原文在報告相關變項(性別、下顎、臼齒)比較時標示 P>.05,本卡因此只採其測量時間點與平均值,並將「術前痛者術後也較容易痛」列為方向性觀察,不作定論。
  • F9|2024 年系統性回顧與統合分析(質性統整 57 篇、統合分析 3 篇):中度至重度術後疼痛在根管治療後較常出現於術後 48 至 72 小時;重度疼痛的頻率在活髓治療與根管治療兩組皆很低。|來源 #4|confidence=moderate|basis=peer_reviewed(SR/MA)|period=2024(檢索至 2022-06-30)|geo: universal|caveat:該篇主比較為活髓治療與單次根管治療,非本題;原文該句同時涵蓋兩種處置的時段敘述,本卡僅取根管治療側的時段分布與「重度疼痛少見」兩點,不作組間優劣推論。
  • F10|2026 年傘狀回顧(檢索自資料庫建立起至 2025-12)納入 12 篇系統性回顧:術後疼痛多以視覺類比或數字評分量表在預設時點量測,急性發作結果報告不一致且定義各異;確定性較高的回顧未顯示單次與多次就診在術後疼痛上有一致或臨床上重要的差異;並建議就診策略可依個案複雜度、感染控制、病人偏好與時程因素決定。|來源 #5|confidence=moderate|basis=peer_reviewed(umbrella review)|period=2026|geo: universal|caveat:作者自述信心受結果定義異質性與原始研究重疊限制。
  • F11|前瞻性臨床研究:急性發作(flare-up)操作定義為疼痛與/或腫脹而需要在預約之間安排緊急處置;408 顆接受根管治療的牙齒中發生率 1.71%;卡方檢定顯示發生率與根尖周圍透亮區(原文 periradicular radiolucency)的存在有直接相關。|來源 #6|confidence=low|basis=peer_reviewed(單一機構前瞻性研究)|period=2010(收案 2006-06 至 2007-06)|geo: universal|caveat:單一牙科機構、樣本 408 顆牙,不得當作一般族群的發生率;本卡用於說明「什麼叫急性發作」與「這是會被記錄的事件」。⚠️ 譯名對照(2026-08-06 回讀 span 校正):本條原文為 `periradicular radiolucency`(牙根周圍),與 F4 之 `periapical radiolucency`(根尖)分屬不同來源的不同用語,本卡各自照譯、不互相替代、不合併引用。
  • F12|綜論:急性發作為原本無症狀的牙髓與/或根尖周圍病理狀況之急性惡化;預約之間疼痛的成因為對牙髓或根尖周圍組織的機械、化學與/或微生物刺激,機械刺激包含根管過度器械操作與充填材料經根尖孔擠出。|來源 #7|confidence=low|basis=peer_reviewed(敘述性綜論,非統合分析)|period=2014|geo: universal|caveat:綜論性質,未提供量化風險;本卡僅用其定義與成因分類。⚠️ 譯名對照(2026-08-06 回讀 span 校正):原文為 `overinstrumentation of the root canal`,本卡譯為「根管的過度器械操作」。先前正文把它具體化成「超出某一長度」的說法,原文沒有提到任何長度基準,已改回照原文的一般性表述(舊句本欄刻意不逐字複製,避免被當成現行敘述抽走)。
  • F13|系統性回顧與統合分析(質性 12 篇、量性 9 篇):調整咬合在器械階段後 6、12、24、48 小時與封填後 6、12 小時皆未測到降低術後疼痛;GRADE 評為中等確定性。|來源 #8|confidence=moderate|basis=peer_reviewed(SR/MA)|period=2021(檢索至 2021-04;本卡 2026-08-06 檢索同題回顧另見 2020 年兩篇,未見 2022 年以後更新版)|geo: universal|caveat:結果為「未測到差異」,非「不可以做」;是否調整咬合屬臨床判斷。
  • F14|系統性回顧與統合分析(含試驗序列分析):納入 18 篇研究、1192 位受試者;與不放置根管內藥物相比,放置氫氧化鈣在術後 24 小時疼痛較低(標準化平均差 -0.71,95% 信賴區間 -1.38 至 -0.03;4 篇試驗、226 人;I²=78%;中等確定性);作者指出顯著異質性限制結果穩健性。|來源 #9|confidence=moderate|basis=peer_reviewed(SR/MA)|period=2022|geo: universal|caveat:本卡 2026-08-06 檢索另見 2023 年同題回顧(PMID 37205901,9 篇研究),其合併平均差 -4.57(信賴區間 -16.25 至 7.11)、I²=95%,信賴區間跨過 0;兩篇並存代表此題證據未收斂,本卡僅用於說明「多次就診中間為何放藥」,不作任何材料或處置建議
  • F15|2026 年隨機臨床試驗:59 位壞死牙髓合併根尖病灶的病人隨機分派(單次 28/兩次 31),兩次就診組於根管內放置氫氧化鈣 10 至 14 天;平均追蹤 2.8 年、42 人完成;癒合結果未達統計顯著差異,作者明言未證明優越、非劣或等效。|來源 #10|confidence=low|basis=peer_reviewed(單一 RCT,小樣本)|period=2026|geo: universal|caveat:本卡僅引用其「10 至 14 天」的實際作法作為間隔的一個實例,不得讀成建議間隔或兩次較佳
  • F16|八年回溯研究(某研究所層級牙髓病科 2008 至 2016 年後牙根管治療):治療後 4 個月以後才裝牙冠者,被拔除的可能性約為 4 個月內裝牙冠者的 3 倍(風險比 3.38,95% 信賴區間 1.56 至 6.33,P = .002);以複合樹脂或汞合金堆核修復者相對於做牙冠者為 2.29 倍(95% 信賴區間 1.29 至 4.06,P = .005)。|來源 #11|confidence=low|basis=peer_reviewed(單一機構回溯性研究)|period=2016|geo: universal|caveat:回溯性設計只能讀成關聯;族群為教學單位的後牙;與 F17 方向不一致,本卡並陳不收斂
  • F17|瑞典社會保險署登錄資料研究:2009 年 50314 筆第一大臼齒根管治療後的直接充填,依「根管充填完成至直接充填放置」的時間分五組,後續 5 年的正向再治療(原文 orthograde retreatment,指經由牙冠、走原根管路徑的再治療,非手術)(p = 0.089)、根尖手術(p = 0.161)與拔除(p = 0.737)皆無統計顯著的時間相關差異;作者結論為該段時間長短未影響 5 年結果。該研究背景另引述體外滲漏研究顯示暫時性填補僅提供短期封閉。|來源 #12|confidence=moderate|basis=peer_reviewed(全國登錄資料回溯研究)|period=2025(資料年 2009,追蹤 5 年)|geo: universal(瑞典資料,非制度性內容)|caveat:對象為直接充填而非牙冠,與 F16 不是同一件事;登錄資料無臨床細節;「暫時填補僅短期封閉」係該篇引述之體外研究背景,非其本身之臨床結果。
  • F18|系統性回顧與統合分析:持續性牙痛定義為治療後六個月以上仍有疼痛;26 篇研究、5777 顆牙納入、2996 顆有追蹤資料,估計盛行率 5.3%(95% 信賴區間 3.5% 至 7.2%),異質性高(I²=80%);次群組中前瞻性研究 7.6%、回溯性研究 0.9%。|來源 #13|confidence=moderate|basis=peer_reviewed(SR/MA)|period=2010(本卡 2026-08-06 檢索未見取代本篇之新版統合分析)|geo: universal|caveat:異質性高;用於「持續痛要回診重新診斷」,不用於估計個人風險。
  • F19|回溯性研究:97 位因牙源性感染住院的病人中,19 位(20%)出現深頸部間隙感染;下顎來源者 16/55(29%)高於上顎來源者 3/42(7%)(P ≤ 0.009);作者結論指出,除典型判準(發燒、頸部腫脹、呼吸困難、吞嚥困難、張口受限、白血球增高、C 反應蛋白升高)外,住院判準應納入下顎來源之牙源性感染與牙齒膿瘍的存在。|來源 #14|confidence=low|basis=peer_reviewed(單一醫學中心回溯世代)|period=2015(收案 2008-01 至 2012-06)|geo: universal|caveat:族群為已住院之耳鼻喉科病人,為醫師的住院判準,不是病人的自我診斷工具;本卡據此列紅旗徵象並要求立即就醫,屬保守取向的編輯決定。
  • F20|《醫療法》第 81 條:醫療機構診治病人時,應向病人或其法定代理人、配偶、親屬或關係人告知其病情、治療方針、處置、用藥、預後情形及可能之不良反應。|來源 #15|confidence=high|basis=law|period=現行條文(2026-08-06 以 ego-browser 實載,標題「醫療法§81-全國法規資料庫」,條文逐字對得上)|geo: TW|caveat:條文轉述,非法律意見;本卡據此把用藥問題全部導回醫師,未提供任何用藥建議。
  • F21|《醫療法》第 87 條第 2 項:醫學新知或研究報告之發表、病人衛生教育、學術性刊物,未涉及招徠醫療業務者,不視為醫療廣告。|來源 #16|confidence=high|basis=law|period=現行條文(2026-08-06 以 ego-browser 實載逐字)|geo: TW|caveat:本卡定位依據。
  • F22|《全民健康保險法》第 41 條第 1 項:醫療服務給付項目及支付標準,由保險人與相關機關、專家學者、被保險人、雇主及保險醫事服務提供者等代表共同擬訂,報主管機關核定發布。|來源 #17|confidence=high|basis=law|period=現行條文(2026-08-06 以 ego-browser 實載逐字)|geo: TW|caveat:本卡據此把給付問題指向健保署現行公告與費用卡,不作個案給付判定。
  • F23[結構性整理]|三級觀察框架(研究測量點記錄到的反應/該主動回診/立即就醫紅旗)、與 KM-DENTAL-18/26 的 canonical 分工聲明,以及「疼痛走勢反轉就回診」「腫脹或瘻管請主動回診」「暫時填補脫落請回診處理」等保守取向的就醫安全網措辭,皆為本站編輯定義之結構與編輯決定,非事實宣稱、非文獻導出之閾值。|confidence=n/a|basis=editorial|geo: TW|caveat:不得標為待驗(避免製造假查證工作)。⚠️ 2026-08-06 CX 對抗審 29-1 命中後的硬規則:本卡的分級一原標題把研究測量到的反應說成「文獻預期範圍內」,等於把 F9 的 48 至 72 小時群體測量窗寫成個人可等待的範圍,並在分級二、checklist 與 FAQ 三處把 72 小時做成行動門檻——已全數移除(舊句刻意不逐字複製)。本卡此後不得出現任何「滿 N 小時/N 天之後才回診」形態的門檻;回診觸發條件一律以走勢(正在加重、好轉後又加重)與徵象(腫脹、瘻管)表述,走勢反轉發生在第一天與第三天同等處理。

FAQ

什麼情況要立刻就醫、不能等?
若出現發燒、頸部腫脹、吞嚥困難、呼吸不順、張口受限或臉部腫脹擴大,不要等下一次預約,請立即就醫由醫師判斷 [F19][F23]。
どのような場合に直ちに受診し、待ってはいけませんか。発熱、頸部腫脹、嚥下困難、呼吸のしづらさ、開口障害、または顔面腫脹の拡大があるときは、次の予約を待たず直ちに医療を受けてください [F19][F23]。
When should I seek immediate care rather than wait?With fever, neck swelling, swallowing difficulty, breathing difficulty, limited mouth opening, or expanding facial swelling, do not wait for the next appointment; seek immediate medical assessment [F19][F23].
抽神經到底會痛幾天?
文獻沒有給「幾天」這個答案,只給測量點上的群體比例:術後 24 小時仍有疼痛者約 40%,一週約 11%;強度在 0 至 100 分量表上由治療前的 54 分降到 24 小時的 24 分、一週的 5 分 [F2]。回顧作者的結論是疼痛在一天內中等幅度下降、7 天內降到極低的程度 [F3]。這是群體平均,個人差異大;你的情況請以治療你的牙醫師說明為準 [F3]。
根管治療後の痛みは結局何日ですか。文献は日数を答えず、測定時点の集団割合を示す。術後 24 時間で痛みがある人は約 40%、1 週で約 11%。0 から 100 の尺度で強度は治療前 54、24 時間 24、1 週 5 だった [F2]。レビューは 1 日以内に中等度に下がり、7 日以内に最小レベルまで下がると結論した [F3]。これは集団平均で個人差は大きい。あなたの場合は治療した歯科医師の説明を優先する [F3]。
Exactly how many days will a root canal hurt?The literature does not give a number of days; it gives population proportions at measurement points: about 40% still had pain at 24 hours and 11% at one week. On a 0-to-100 scale, intensity fell from 54 before treatment to 24 at 24 hours and 5 at one week [F2]. The review concluded that pain declined moderately within one day and substantially to minimal levels within 7 days [F3]. Those are population averages; individual variation is large. Use the treating dentist's explanation for your situation [F3].
治療後第三天比第二天還痛,是不是失敗了?
單憑「第三天比第二天痛」這個比較,判定不了治療的成敗。2024 年的回顧記錄到中度至重度疼痛在群體上較常出現於術後 48 至 72 小時 [F9]——**那是研究的時段分布,不是「還沒到某個時間就先忍著」的門檻**;群體方向雖然是一週內降到低點 [F3],但個人的走勢要由醫師判斷。疼痛正在往上走、或伴隨腫脹時,請直接聯絡治療你的院所,不必等到任何時間點 [F11][F23]。
治療後 3 日目のほうが 2 日目より痛い。失敗ですか。「3 日目が 2 日目より痛い」だけでは成功・失敗は判定できない。2024 年レビューは集団で中等度から重度の疼痛が術後 48 から 72 時間に多く記録されたとした [F9]。**これは研究上の時期分布であり、ある時点まで我慢する閾値ではない。** 集団では 1 週に低い方向だが [F3]、個人の推移は医師が判断する。痛みが上向き、または腫脹を伴うなら、時点を待たず治療した機関に連絡する [F11][F23]。
It hurts more on day three than day two. Did the treatment fail?“Day three hurts more than day two” alone cannot establish success or failure. The 2024 review recorded moderate-to-severe pain more often in the population at 48 through 72 hours [F9]—**that is a research timing distribution, not a threshold for enduring pain until a particular time**. Population pain was low by one week [F3], but an individual's trajectory needs clinical assessment. If pain is trending upward or comes with swelling, contact the treating practice directly; do not wait for any time point [F11][F23].
