FAQ

根管治療到底要跑幾次才算正常?
文獻沒有給出一個標準次數。現行版 Cochrane 回顧的結論是:沒有證據顯示單次或多次就診其中一種更有效 [F7];2026 年的傘狀回顧則建議,就診次數的安排可依個案複雜度、感染控制需要、病人偏好與時程因素決定 [F10]。要跑幾次請直接問你的牙醫師與理由 [F10]。
根管治療は何回なら普通ですか?標準回数はありません。単回・複数回の優劣を示す根拠はなく、複雑性、感染制御、希望、日程で決めます [F7][F10]。
How many visits are normal for root canal treatment?The literature gives no standard number. The current Cochrane review finds no evidence that either single- or multiple-visit treatment is more effective [F7]. The 2026 umbrella review says visit strategy can depend on case complexity, infection-control needs, patient preference, and timing [F10]. Ask your own dentist how many visits and why [F10].
一次做完會不會比較痛?
現行版 Cochrane 回顧記錄到:一週內回報疼痛的人數比例在單次就診組較高,風險比 1.55(中等確定性證據),在活髓牙的次群組差異較明顯 [F8]。但 2026 年的傘狀回顧綜合 12 篇系統性回顧後認為,確定性較高的回顧並未顯示一致或臨床上重要的差異 [F10]。兩者並陳,代表這是一個「證據還在收斂中」的問題 [F8][F10]。
1 回で終える方が痛いですか?1 週間以内の疼痛報告は単回群で高かった一方、2026 年レビューは一貫した臨床的重要差を示しませんでした。根拠は収束途上です [F8][F10]。
Is finishing it in one visit more painful?The current Cochrane review reports a higher proportion with pain within one week in the single-visit group, risk ratio 1.55 (moderate-certainty evidence), with a clearer subgroup difference in vital teeth [F8]. Yet the 2026 umbrella review of 12 systematic reviews found that higher-certainty reviews did not show a consistent or clinically important difference [F10]. Read together, these findings mean the evidence is still converging [F8][F10].
抽神經很痛嗎?治療後會痛多久?
系統性回顧的群體數字是:治療前疼痛盛行率 81%、治療後 24 小時降到 40%、一週降到 11%;強度(0 至 100 分)由 54 分降到 24 分再降到 5 分 [F12]。治療中經常需要追加補充麻醉,會痛可以當場說 [F12]。若治療後六個月仍持續疼痛,文獻估計盛行率約 5.3%,且其中相當比例的原因不在那顆牙,應回診重新診斷 [F13][F14]。
治療は痛いですか。どのくらい続きますか?群体値は 81%、24 時間後 40%、1 週後 11% で、強度は 54、24、5 です。6 か月以上続く痛みは約 5.3% で、再診断を受けます [F12][F13][F14]。
Does “nerve removal” hurt, and how long does pain last afterward?In the systematic review’s group figures, pain prevalence was 81% before treatment, 40% at 24 hours, and 11% at one week; intensity on a 0-to-100 scale fell from 54 to 24 to 5 [F12]. Supplemental anaesthesia was frequently required, so say so during treatment if it hurts [F12]. If pain persists six months after treatment, estimated prevalence is about 5.3%, and a substantial proportion of causes are outside that tooth; return for re-diagnosis [F13][F14].
