  • F3｜現有關於人類拔牙傷口修復的研究受到明顯侷限，且未能評估硬組織缺損各區塊所發生的組織變化｜來源 #1｜confidence=verified｜basis=peer_reviewed（PMID 18498382，人類組織學研究）｜period=2008｜geo: universal｜span:「The available studies on extraction wound repair in humans are affected by significant limitations and have failed to evaluate tissue alterations occurring in all compartments of the hard tissue defect」｜caveat：此為該研究引言對既有文獻的評述，本卡引用其作為「逐日表不存在」的依據。
  • F4｜27 份人類拔牙窩切片分屬早期（2 至 4 週，n=10）、中期（6 至 8 週，n=6）、晚期（12 至 24 週，n=11）三個癒合階段，觀察期共 6 個月｜來源 #1｜confidence=verified｜basis=peer_reviewed（PMID 18498382）｜period=2008｜geo: universal｜span:「Twenty-seven biopsies, representative of the early (2-4 weeks, n=10), intermediate (6-8 weeks, n=6), and late phase (12-24 weeks, n=11) of healing, were collected and analysed」｜caveat：切片取樣時點即為分期定義，非「癒合完成時間」；樣本數小，且取樣牙位未於摘要載明，禁外推為第三大臼齒專屬數據。
  • F5｜早期癒合階段大量存在的肉芽組織，於早期到中期之間被暫時性基質與編織骨取代；血管結構與巨噬細胞密度自 2 至 4 週起隨時間緩慢下降；成骨細胞於 6 至 8 週達到高點後大致穩定｜來源 #1｜confidence=verified｜basis=peer_reviewed（PMID 18498382）｜period=2008｜geo: universal｜span:「Granulation tissue that was present in comparatively large amounts in the early healing phase of socket healing, was in the interval between the early and intermediate observation phase replaced with provisional matrix and woven bone. The density of vascular structures and macrophages slowly decreased from 2 to 4 weeks over time. The presence of osteoblasts peaked at 6-8 weeks and remained almost stable thereafter」｜caveat：半定量組織學觀察、樣本 27 份；描述的是組織成分變化，非臨床可見的「洞封閉」時點。
  • F6｜人類拔牙窩內硬組織形成存在很大的個體差異；臨時性結締組織在癒合的起初數週穩定形成，但礦化骨質沉積的時間區間則難以預測得多｜來源 #1｜confidence=verified｜basis=peer_reviewed（PMID 18498382）｜period=2008｜geo: universal｜span:「The present findings demonstrated that great variability exists in man with respect to hard tissue formation within extraction sockets. Thus, whereas a provisional connective tissue consistently forms within the first weeks of healing, the interval during which mineralized bone is laid down is much less predictable」｜caveat：本卡不得由此推導任何「幾天會好」的天數承諾；「起初數週」為原文 first weeks 之對譯，非精確天數。
  • F7｜系統性回顧（20 篇納入研究）：6 個月時水平向縮減 3.79 ± 0.23 毫米，大於垂直向縮減（頰側 1.24 ± 0.11 毫米、近心側 0.84 ± 0.62 毫米、遠心側 0.80 ± 0.71 毫米）；垂直向尺寸變化百分比 6 個月時為 11% 至 22%；水平向尺寸變化百分比 3 個月時 32%、6 至 7 個月時 29% 至 63%；再進入手術研究顯示起初 3 至 6 個月快速縮減、其後轉緩｜來源 #2｜confidence=verified｜basis=peer_reviewed（PMID 22211303，系統性回顧，檢索 MEDLINE 與 CENTRAL）｜period=2012｜geo: universal｜span:「In human hard tissue, horizontal dimensional reduction (3.79 ± 0.23 mm) was more than vertical reduction (1.24 ± 0.11 mm on buccal, 0.84 ± 0.62 mm on mesial and 0.80 ± 0.71 mm on distal sites) at 6 months. Percentage vertical dimensional change was 11-22% at 6 months. Percentage horizontal dimensional change was 32% at 3 months, and 29-63% at 6-7 months」「These studies demonstrated rapid reductions in the first 3-6 months that was followed by gradual reductions in dimensions thereafter」｜caveat：加權平均與百分比為研究層級彙整、非個人預測值；納入研究以未受干擾之自然癒合窩洞為限。
  • F8｜針對 46 位病人拔除前臼齒或臼齒後、以石膏模型與線性放射線分析追蹤 12 個月的前瞻性研究，結果為拔牙部位的主要變化發生在拔牙後 1 年之內｜來源 #3｜confidence=verified｜basis=peer_reviewed（PMID 12956475，前瞻性臨床與放射線研究）｜period=2003｜geo: universal｜span:「The tissue changes after removal of a premolar or molar in 46 patients were evaluated in a 12-month period by means of measurements on study casts, linear radiographic analyses, and subtraction radiography. The results demonstrated that major changes of an extraction site occurred during 1 year after tooth extraction」｜caveat：PubMed 摘要未載該研究的骨填充與寬度縮減數值，本卡因此不引用該研究的任何量化數字，僅引用「1 年內有主要變化」此一結論句。
  • F9｜乾槽症為拔牙併發症，較常涉及下顎臼齒；伴隨術後 2 至 3 天發展出的劇烈疼痛，可能有或沒有口臭，窩洞可能部分或完全沒有血塊，並增加術後回診｜來源 #4｜confidence=verified｜basis=peer_reviewed（PMID 36156769，Cochrane 系統性回顧，49 篇試驗、6,771 位受試者）｜period=2022（檢索至 2021-09-28）｜geo: universal｜span:「Alveolar osteitis (dry socket) is a complication of dental extractions more often involving mandibular molar teeth. It is associated with severe pain developing 2 to 3 days postoperatively with or without halitosis, a socket that may be partially or totally devoid of a blood clot, and increased postoperative visits」｜caveat：此為該回顧的背景描述段，屬臨床共識性定義；不構成自我診斷工具。
  • F10｜乾槽症為拔牙後血塊的部分或全部喪失，導致通常於術後 1 至 5 天開始的劇烈疼痛，臨床可見暴露的齒槽骨、壞死組織碎屑、口臭與檢查時觸痛；統合分析顯示吸菸者發生乾槽症的勝算增加超過 3 倍，合併發生率吸菸者約 13.2%、非吸菸者約 3.8%｜來源 #5｜confidence=verified｜basis=peer_reviewed（PMID 35877395，系統性回顧，11 篇納入研究）｜period=2022（檢索至 2022-03）｜geo: universal｜span:「It is the partial or total loss of the post-extraction blood clot, resulting in severe pain that usually starts one to five days postoperatively, with clinical evidence of exposed alveolar bone, necrotic debris, halitosis, and tenderness on examination」「Based on a meta-analysis, tobacco smokers had a more than three-fold increase in the odds of dry socket after tooth extraction. Overall, the combined incidence of dry socket in smokers was found to be about 13.2% and in non-smokers about 3.8%」｜caveat：作者自述納入研究異質性高（拔除牙位與年齡層不同）；為觀察性研究之合併，屬關聯性而非因果。
  • F11｜乾槽症盛行率在常規拔牙為 1% 至 5%，在手術性拔除的第三大臼齒可達 30% 以上｜來源 #4｜confidence=verified｜basis=peer_reviewed（PMID 36156769，Cochrane 系統性回顧）｜period=2022｜geo: universal｜span:「The prevalence of dry socket varies from 1% to 5% in routine dental extractions to upwards of 30% in surgically extracted third molars」｜caveat：此為該回顧用於計算 NNT 的背景參數範圍，非其自行合成之統合估計值；不得寫成「文獻證實常規拔牙乾槽症率為 1 至 5%」。
  • F12｜統合分析納入 28 篇研究、共 41,859 顆阻生下顎第三大臼齒拔除，乾槽症整體盛行率估計為 6.7%（95% 信賴區間 4.6% 至 9.1%），研究間異質性相當大｜來源 #6｜confidence=verified｜basis=peer_reviewed（PMID 38432484，系統性回顧與統合分析）｜period=2024｜geo: universal｜span:「Our meta-analysis included twenty-eight eligible studies, encompassing a total of 41,859 impacted mandibular third molar extractions. The overall prevalence of dry socket (DS) following impacted mandibular third molar extractions was estimated at 6.7 % (95 % CI 4.6-9.1 %), indicating considerable heterogeneity among the studies」｜caveat：限阻生下顎第三大臼齒；異質性大、統合迴歸未能找出異質性來源；為族群盛行率非個人風險。
  • F13｜Cochrane 系統性回顧（49 篇試驗、6,771 位受試者）：與安慰劑相比，拔牙前與拔牙後 24 小時使用 0.12% 與 0.2% chlorhexidine 漱口水實質降低乾槽症風險（勝算比 0.38，95% CI 0.25 至 0.58，6 篇試驗、1,547 位受試者，中等確定性）；拔牙後窩洞內放置 0.2% chlorhexidine 凝膠使勝算降低 58%（勝算比 0.44，95% CI 0.27 至 0.71，7 篇試驗、753 位受試者，中等確定性）；並有 0.12%、0.2% 漱口水與味覺改變、牙齒染色、口腔炎等輕微不良反應關聯的證據｜來源 #4｜confidence=verified｜basis=peer_reviewed（PMID 36156769）｜period=2022｜geo: universal｜span:「rinsing with chlorhexidine mouthrinses (0.12% and 0.2% concentrations) both before and 24 hours after extraction(s) substantially reduced the risk of developing dry socket with an OR of 0.38」「placing chlorhexidine gel intrasocket after extractions reduced the odds of developing a dry socket by 58% with an OR of 0.44」「some evidence for the association of minor adverse reactions with use of 0.12%, 0.2% chlorhexidine mouthrinses (alteration in taste, staining of teeth, stomatitis)」｜caveat：除 5 篇外全部納入研究之受試者為第三大臼齒拔除者，多由口腔外科醫師執行；屬醫師開立範圍，本卡不推薦任何產品、濃度或品牌。
  • F14｜Cochrane 系統性回顧的治療端結果：兩篇研究、80 位受試者顯示舊配方 Alvogyl 在第 7 天的疼痛優於氧化鋅丁香油（平均差 -1.40，95% CI -1.75 至 -1.04），作者評為極低確定性證據；另 9 種治療乾槽症的介入各僅單一研究，證據不足以判定效果｜來源 #4｜confidence=verified｜basis=peer_reviewed（PMID 36156769）｜period=2022｜geo: universal｜span:「Two studies, with 80 participants, showed that Alvogyl (old formulation) is more effective than zinc oxide eugenol at reducing pain at day 7 (mean difference (MD) -1.40, 95% CI -1.75 to -1.04; P < 0.00001; 2 studies, 80 participants; very low-certainty evidence)」「A further nine interventions for the treatment of dry socket were evaluated in single studies, providing insufficient evidence to determine their effects」｜caveat：極低確定性；本卡引用其「治療端證據不足」的方向，不作任何處置推薦。
  • F27｜系統性回顧與統合分析：因腫瘤原因接受抗骨吸收藥物治療者，拔牙後藥物相關顎骨壞死發生率 3.2%，顯著高於因骨質疏鬆口服抗骨吸收藥物者的 0.15%；採用調整過的拔牙術式可顯著降低顎骨壞死發生｜來源 #14｜confidence=verified｜basis=peer_reviewed（PMID 26362756，系統性回顧與統合分析）｜period=2015｜geo: universal｜span:「The risk of MRONJ after dental extraction was significantly higher in patients treated with ARD for oncological reasons (3.2%) than in those treated with per os ARD for OP (0.15%)」「Dental extraction performed with adjusted extraction protocols decreased significantly MRONJ development」｜caveat：族群層級發生率、非個人機率；本卡引用其作為「用藥史必須告知牙醫師」的依據，不作任何停藥或用藥建議。
  • F15｜Cochrane 系統性回顧（23 篇試驗、約 3,206 位受試者）：預防性抗生素可能使拔除阻生智齒後的乾槽症風險降低 34%（風險比 0.66，95% CI 0.45 至 0.97，13 篇研究、1,882 位受試者，低確定性），即 46 人服藥可預防 1 例；感染併發症約降低 66%（風險比 0.34，12 篇研究、1,728 位受試者，低確定性），即 19 人服藥可預防 1 例；作者提醒因抗藥性菌盛行率上升，應依個別病人狀況評估是否及何時給藥｜來源 #7｜confidence=verified｜basis=peer_reviewed（PMID 33624847，Cochrane 系統性回顧）｜period=2021（檢索至 2020-04-16）｜geo: universal｜span:「Antibiotics may also reduce the risk of dry socket by 34% (RR 0.66, 95% CI 0.45 to 0.97; 1882 participants; 13 studies; low-certainty evidence), which means that 46 people (95% CI 29 to 62) need to take antibiotics to prevent one case of dry socket following extraction of impacted wisdom teeth」「clinicians should evaluate if and when to prescribe prophylactic antibiotic therapy before a dental extraction for each patient on the basis of the patient's clinical conditions」｜caveat：23 篇中 21 篇僅納入接受阻生第三大臼齒拔除的健康者，作者明言結果可能無法類推至所有拔牙病人；本卡不對任何處方用藥作建議。
  • F16｜實證牙科評述（針對 F10 之系統性回顧）：11 篇研究來自 10 個國家、共 10,195 位病人（3,007 位吸菸者、7,188 位非吸菸者）；9 篇品質評為 good、2 篇 intermediate；所有納入研究之證據等級為五級量表中的第三或第四級｜來源 #8｜confidence=verified｜basis=peer_reviewed（PMID 37814003，Evidence-Based Dentistry 之結構式評述）｜period=2023｜geo: universal｜span:「Eleven studies from ten different countries representing a total of 10,195 patients (3007 smokers and 7188 non-smokers) were included in the final analysis. Nine studies were classified as having "good" quality and two as "intermediate," while all of the studies have the third or fourth level of evidence」｜caveat：文獻類型為對他人系統性回顧的評述（commentary），非原始研究；本卡引用其樣本組成與證據等級評定，用以標示 F10 的證據強度上限。
  • F17｜2002 年批判性回顧的目的為統整乾燥窩洞（乾槽症）的描述性定義並檢視其病因與致病機轉；該文未進行資料的統合分析｜來源 #9｜confidence=verified｜basis=peer_reviewed（PMID 12190139，critical review）｜period=2002｜geo: universal｜span:「The objective of this article is to harmonize descriptive definitions for the condition known as alveolar osteitis and to critically review and discuss the aetiology and pathogenesis of alveolar osteitis」「A meta-analysis of data was not done」｜caveat：本卡引用其作為「定義需要統整、診斷須由臨床檢查」的依據，不引用其任何處置建議；發表年代較早。
  • F18｜系統性回顧與統合分析（8 篇隨機研究）：溫鹽水漱口與其他抗菌漱口水在乾槽症發生率上無顯著差異（P 值大於 0.05）；作者指出多數納入研究偏差風險高，需更多研究驗證｜來源 #10｜confidence=verified｜basis=peer_reviewed（PMID 34509363，系統性回顧與統合分析）｜period=2021（檢索至 2020-08-30）｜geo: universal｜span:「This review found no significant difference (P > 0.05) in the incidence of alveolar osteitis between WSMB and other antimicrobial rinses」「more studies are needed to validate these findings, as most of the studies reviewed had a high level of bias」｜caveat：僅 8 篇納入、偏差風險高；「無顯著差異」不等於「等效」，亦不等於推薦或不推薦任何漱口方式。
  • F19｜339 位病人、五類牙槽手術之病人自述研究（10 公分視覺類比量表，術後第 1 週逐日與第 14 天）：癒合前 3 天翻瓣手術性拔除的整體出血與疼痛曲線下面積較高（出血平均 5.6、疼痛平均 7.5）；兩週整體經驗顯示各組症狀快速消退、各項分數降至接近零；術後 1 週併發症比例單純拔牙 4.8%、翻瓣手術性拔除 1.5%｜來源 #11｜confidence=verified｜basis=peer_reviewed（PMID 26970296，比較性臨床研究，香港與南京兩中心）｜period=2017｜geo: universal｜span:「For the first 3 days of healing, area-under-the-curve (AUC) analyses showed that transalveolar extraction (TE) resulted in significantly higher overall bleeding and pain (AUC: Bleeding Mean = 5.6, Pain Mean = 7.5)」「Two-week overall experience showed the symptoms quickly subsided for all groups」「The VAS scores for all POAs parameters were generally low and decreased to nearly zero over the study period」｜caveat：非隨機、兩中心連續收案；為群體層級走勢，不代表個別病人的必然結果；同 #20 卡 F5 錨；併發症比例之組間差異方向與體感不一致（TE 併發症比例反而較低），本卡因此不以該比例作組間比較宣稱。
  • F20｜系統性回顧（15 篇納入）：因害怕出血或術後出血而中斷抗血栓藥物會提高血栓栓塞事件風險；所檢視的局部止血措施包含紗布加壓等方式｜來源 #12｜confidence=verified｜basis=peer_reviewed（PMID 30155575，系統性回顧）｜period=2019｜geo: universal｜span:「The interruption of antithrombotics prior to tooth removal because of the fear of bleeding or following postoperative bleeding increases the risk of thromboembolic events」「The investigated haemostatics included gauze pressure」｜caveat：同 #20 卡 F8、#28 卡 F14 錨；本卡僅引用止血措施類別與停藥風險，不推薦任何特定止血材料或藥物。
  • F21｜Cochrane 系統性回顧（62 篇試驗、4,643 位受試者）：下顎智齒拔除手術通常伴隨短期術後疼痛、腫脹與開口受限；較少見的情況可能發生感染、乾槽症與三叉神經損傷｜來源 #13｜confidence=verified｜basis=peer_reviewed（PMID 32712962，Cochrane 系統性回顧）｜period=2020（檢索至 2019-07-08）｜geo: universal｜span:「Surgery is commonly associated with short-term postoperative pain, swelling and trismus. Less frequently, infection, dry socket (alveolar osteitis) and trigeminal nerve injuries may occur」｜caveat：此為該回顧的背景描述段；該回顧本身比較的是不同術式，其療效結論本卡未引用；多篇納入研究排除了健康狀況不佳者。
  • F22｜口腔外科中發生比例居前的併發症為抗凝血治療病人的出血、免疫抑制病人的感染、使用抗骨吸收藥物病人的骨壞死；水腫、疼痛與發炎亦為常見術後問題｜來源 #15｜confidence=verified｜basis=peer_reviewed（PMID 40952869，回顧 23 篇文獻之系統性回顧）｜period=2024｜geo: universal｜span:「The most prevalent complications in oral surgery are hemorrhage in anticoagulated patients, infections in immunosuppressed patients, and osteonecrosis in patients who take antiresorptive drugs」「Edema, pain, and inflammation are also common post-operative concerns」｜caveat：同 #20 卡 F25 錨；情境為服用多重藥物的高風險族群，非一般拔牙者的預期；本卡引用其併發症類別，不引用其處置建議。
  • F23｜口腔為複雜的微環境，受口腔運動、唾液流動與細菌生物膜影響，這些因素可能導致窩洞癒合延遲與拔牙後併發症｜來源 #16｜confidence=verified｜basis=peer_reviewed（PMID 39626339，敘述性回顧）｜period=2025｜geo: universal｜span:「The oral cavity is a complex microenvironment, influenced by oral movements, salivary flow, and bacterial biofilms. These factors can contribute to delayed socket healing and the onset of post-extraction complications」｜caveat：文獻類型為生物材料領域的敘述性回顧，非臨床試驗；本卡僅引用其對口腔環境的機制性描述，未引用任何材料或療法的效能宣稱。
  • F24｜《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 #17｜confidence=verified（2026-08-05 實測回應 200、條文逐字對得上）｜basis=law｜period=現行條文｜geo: TW｜caveat：條文引述，非法律意見；同 #20 卡 F21、#28 卡 F18 錨。

FAQ

拔牙的洞多久才會癒合？
**文獻沒有一個適用於所有人的天數。** 可引用的是：臨時性結締組織在起初數週穩定形成，但礦化骨質沉積的時間區間難以預測得多 [F6]；組織學切片在 2 至 4 週看到大量肉芽組織，於 6 至 8 週已轉為暫時性基質與編織骨，晚期取樣期間為 12 至 24 週 [F4][F5]；外形層面在起初 3 至 6 個月變化較快、1 年內仍在改變 [F7][F8]。實際進度須由你的牙醫師評估。
抜歯後の穴はどのくらいで治癒しますか？ — **全員に当てはまる日数は文献にありません。** 引用できるのは、暫定的結合組織が最初の数週間に一貫して形成される一方、石灰化骨の沈着時期ははるかに予測しにくいこと [F6]、組織学標本では 2 〜 4 週に多量の肉芽組織が見られ、6 〜 8 週には暫定マトリックスと網状骨へ移り、後期の採取期間は 12 〜 24 週であること [F4][F5]、形態は最初の 3 〜 6 か月に速く変わり、1 年以内も変化することです [F7][F8]。実際の経過は歯科医師が評価します。
How long will an extraction socket take to heal? — **The literature gives no number of days that applies to everyone.** What can be cited is that provisional connective tissue consistently forms in the first weeks, but the interval for mineralized-bone deposition is much less predictable [F6]; histology found much granulation tissue at 2 to 4 weeks, provisional matrix and woven bone by 6 to 8 weeks, and late samples at 12 to 24 weeks [F4][F5]; contour changes faster in the first 3 to 6 months and continues to change within 1 year [F7][F8]. Your dentist must assess actual progress.
拔智齒的洞多久癒合？跟一般拔牙差在哪？
**差別主要在前幾天的體感與併發症風險，不在骨改建的階段框架。** 手術性拔除在前 3 天的出血與疼痛曲線下面積較高 [F19]；下顎智齒手術常伴隨短期疼痛、腫脹與開口受限，較少見的情況可能發生感染、乾槽症與三叉神經損傷 [F21]；乾槽症在手術性拔除的第三大臼齒可達 30% 以上、阻生下顎第三大臼齒的統合估計為 6.7% [F11][F12]。至於骨癒合時程，本卡引用的組織學與尺寸研究並非以第三大臼齒取樣，故不另給數字 [F4][F7][F26]。
智歯の穴はどのくらいで治癒しますか？通常の抜歯と何が違いますか？ — **主な違いは最初の数日の体感と合併症リスクであり、骨リモデリングの段階枠組みではありません。** 外科的抜歯は最初の 3 日の出血と疼痛の曲線下面積が高いです [F19]。下顎智歯手術には短期の疼痛、腫脹、開口制限が通常伴い、頻度は低いものの感染、ドライソケット、三叉神経損傷が起こり得ます [F21]。外科的に抜去する第三大臼歯でドライソケットは 30% 以上になり得、埋伏下顎第三大臼歯の統合推定は 6.7% です [F11][F12]。骨治癒時期については、本カードが引用する組織学・寸法研究は第三大臼歯を採取していないため、別の数値を示しません [F4][F7][F26]。
How long does a wisdom-tooth socket take to heal, and how is it different from an ordinary extraction? — **The main difference is the first days' experience and complication risk, not the stage framework for bone remodelling.** Surgical extraction has higher bleeding and pain area-under-the-curve in the first 3 days [F19]. Mandibular wisdom-tooth surgery commonly brings short-term pain, swelling, and restricted opening; less commonly it may bring infection, dry socket, and trigeminal nerve injury [F21]. Dry socket can be upwards of 30% in surgically extracted third molars, and the pooled estimate for impacted mandibular third molars is 6.7% [F11][F12]. The histology and dimensional studies cited here did not sample third molars, so this card gives no separate bone-healing numbers [F4][F7][F26].
怎麼分辨乾槽症和一般術後痛？
**看走勢與看窩洞。** 一般術後不適的群體走勢是逐日遞減、兩週內接近零 [F19]；乾槽症的文獻描述是術後 2 至 3 天（或 1 至 5 天）發展出劇烈疼痛，窩洞可能部分或完全沒有血塊，可伴口臭、暴露骨面、壞死組織碎屑與觸痛 [F9][F10]。**若疼痛未逐漸緩解、或在術後數日明顯加劇，就需要回診評估**；是否為乾槽症仍須由牙醫師檢查窩洞判斷，本卡不能用於自我診斷 [F17]。
ドライソケットと通常の術後痛はどう分けますか？ — **経過と窩洞を見ます。** 通常の術後不快感は集団レベルで日ごとに低下し、2 週間以内にほぼゼロへ近づきます [F19]。ドライソケットは、術後第 2 〜 第 3 日（または第 1 〜 第 5 日）に激痛が発現し、窩洞が血餅を部分的または完全に欠き、口臭、露出骨面、壊死組織片、圧痛を伴い得ると記載されています [F9][F10]。**疼痛が徐々に軽くならない、または術後数日に明らかに強くなるなら、再診評価が必要です。** ドライソケットかは、なお歯科医師が窩洞を診察して判断する必要があり、本カードは自己診断には使えません [F17]。
How can I tell dry socket from ordinary postoperative pain? — **Look at the trajectory and the socket.** At population level, ordinary postoperative discomfort declines daily and approaches zero within two weeks [F19]. Dry-socket descriptions say severe pain develops on postoperative days 2 to 3 (or 1 to 5); the socket may be partly or completely without a clot, with halitosis, exposed bone, necrotic debris, and tenderness [F9][F10]. **If pain is not gradually easing or gets distinctly worse several days after surgery, you need a return assessment.** A dentist must still examine the socket to determine whether it is dry socket; this card cannot be used for self-diagnosis [F17].
