F-Units（事実単位台帳）

• F0｜Article 87 of Taiwan's Medical Care Act: content that implies or alludes to medical services is deemed medical advertising; publication of medical knowledge or research reports, patient health education, and academic publications are not deemed medical advertising when they do not involve soliciting medical business｜source #24｜confidence=verified (2026-08-06 ego-browser live verification; page title “醫療法§87-全國法規資料庫”; the page contained the exact words “病人衛生教育”)｜basis=law｜period=current statutory text｜geo: TW｜caveat: basis for this card's positioning; statutory quotation, not legal advice.
• F1｜Topic-selection basis = complete reconciliation of GSC data from 14 clinic sites: the 3 queries “拔牙後多久可以刷牙”, “拔完智齒多久可以正常刷牙”, and “拔牙後刷牙可以用牙膏嗎” total 97,237 impressions, from one site ｜source #25｜confidence=high｜basis=internal_dataset｜period=GSC retention window (from 2025-03-22)｜geo: TW｜caveat: impressions are attribute-level figures, not deduplicated traffic; this is internal data, not a medical claim, and will not appear in the published visible layer.
• F2 [editorial organisation]｜The three-area framework—“other teeth / the wound side / the extraction socket itself”—and the operational suggestion to separate brushing from postoperative rinsing are this site's communication structure, organised from F3, F4, F5, F7, F8, and F10｜source #26｜confidence=n/a｜basis=editorial_framework｜period=2026-08-06｜geo: universal｜caveat: not a diagnostic tool or clinical guideline; must not be labelled as a pending-verification claim.
• F3｜UK NHS patient-information page “Wisdom tooth removal” (page reviewed 2024-06-12): postoperative things to do include keeping the wound clean by rinsing gently with mouthwash or warm salt water, and cleaning other teeth carefully while avoiding the affected area so as not to damage stitches or the blood clot over the wound; stitches, if present, dissolve by themselves and a blood clot forms over the wound to help healing; dry socket is described as a painful condition where the blood clot over the tooth socket does not form properly or is dislodged before gum healing; urgent-care situations are bleeding that does not stop, severe or worsening pain and swelling not controlled by painkillers, and pain with a bad taste in the mouth, high temperature, or feeling unwell｜source #21｜confidence=verified (2026-08-06 ego-browser live response 200, title “Wisdom tooth removal - NHS”, exact innerText comparison matched; after same-day CX adversarial review, a second live verification used line-by-line JSON filtering and all spans below matched again)｜basis=official_statement｜period=reviewed 2024-06-12｜geo: universal｜span:「keep the wound clean by rinsing gently with mouthwash or warm salt water」「clean your other teeth carefully, avoiding the affected area so you do not damage your stitches or the blood clot over the wound」「If you had stitches, they'll dissolve by themselves. A blood clot will form over the wound, which helps it to heal.」「you have bleeding that does not stop」「you have pain and swelling that's severe or getting worse and painkillers are not helping」「you have pain with a bad taste in your mouth, a high temperature or feeling unwell」「dry socket – a painful condition where the blood clot over the tooth socket does not form properly or is dislodged before your gum has healed」｜caveat: A UK NHS patient-information page for people in the UK, not a Taiwan or Japan official document and not a clinical guideline with evidence grading; its setting is wisdom-tooth removal (including discussion of general anaesthesia and sedation), and it does not state an hour or day for resuming cleaning or define the extent of the “affected area” (so this card does not set a cleaning boundary for the socket or adjacent tooth gaps). Its dry-socket sentence is a descriptive definition in a complications list; it does not state why a clot is dislodged and must not be read as causal evidence that brushing dislodges a clot. The urgent-care contact route is NHS 111; Taiwan readers should use local emergency information.
• F4｜Scottish Dental Clinical Effectiveness Programme (SDCEP) patient post-treatment leaflet “Post-Treatment Advice for Dental Patients Taking Anticoagulant or Antiplatelet Medication” (March 2022): avoid rinsing until the next day; starting the day after treatment, gently rinse with warm salt water (one teaspoon of salt in a glass of water) 3 to 4 times a day for 5 days; avoid sucking hard or disturbing the clot. The full leaflet does not contain wording relating to brushing (brush / toothbrush)｜source #22｜confidence=verified (2026-08-06 curl live response 200; full text extracted with pdftotext and matched verbatim; a full-text search confirmed no brushing section.

It is a Scottish (UK) guideline output. “No brushing mentioned” is a statement from this site's full-text search, used only to explain the evidence gap; it must not be read as “the guideline opposes brushing.”
• F5｜UK NHS patient-information page “How to keep your teeth clean” (page reviewed 2025-06-30): brush with fluoride toothpaste twice daily for about 2 minutes; adult toothpaste should contain at least 1,350 ppm fluoride; medium or soft bristles suit most people; after brushing spit out excess toothpaste and do not immediately rinse with water, otherwise concentrated fluoride remaining in toothpaste is washed away and its preventive effect reduced; do not use mouthwash immediately after brushing (including fluoridated mouthwash); regular flossing removes plaque at the gum line and may help reduce gum disease, tooth decay, and bad breath, and is recommended before brushing; people with wider gaps can instead use interdental or single-tufted brushes｜source #23｜confidence=verified (2026-08-06 ego-browser live response 200, title “How to keep your teeth clean - NHS”, line-by-line innerText JSON extraction compared verbatim)｜basis=official_statement｜period=reviewed 2025-06-30｜geo: universal｜span:「Brush your teeth with fluoride toothpaste twice a day for about 2 minutes to help keep your teeth and mouth healthy.」「Adults should use a toothpaste that contains at least 1,350 parts per million (ppm) fluoride.」「Medium or soft bristles are best for most people.」「After brushing, spit out any excess toothpaste.」「Don't rinse your mouth immediately after brushing, as it'll wash away the concentrated fluoride in the remaining toothpaste.」「Regular flossing may also reduce gum disease, tooth decay and bad breath by removing plaque that forms along the gum line.」「It's best to floss before brushing your teeth.」「You can use interdental brushes or single-tufted brushes instead of flossing, especially if there are gaps between your teeth.」｜caveat: general oral-health education, not an extraction-specific postoperative guideline; the UK NHS page is for people in the UK, and fluoride-concentration advice and rules may differ by country. This card cites it for the specific content of cleaning other teeth as usual; it must not be read as how to manage an extraction wound.
• F6｜Randomised allocation study (30 healthy participants with at least one periodontal pocket requiring resective surgery, divided into 3 groups: toothbrush plus chlorhexidine with an anti-staining system / toothbrush plus chlorhexidine / toothbrush only; followed to 6 months after surgery): clinical outcomes were good in all 3 groups, with no significant difference between groups at 3 months; authors concluded mechanical plaque control was proven fundamental and sufficient, with no need for chemical plaque control｜source #3｜confidence=verified｜basis=peer_reviewed (PMID 34072369, randomised controlled preliminary study)｜period=2021｜geo: universal｜span:「Thirty healthy subjects, presenting at least one periodontal pocket requiring resective surgery, were selected and randomly distributed to three different groups corresponding to respective post-surgical protocols」「Clinical results were satisfactory in all cases, with no significant differences between groups 3 months after surgery.」「The mechanical plaque control was proven to be fundamental and sufficient in all the six aspects per tooth to guarantee an excellent clinical outcome without the need of chemical plaque control.」｜caveat: periodontal resective surgery, not an extraction socket; sample 30 and described by the authors as a preliminary study. This card cites only the level that mechanical cleaning is a basis of plaque control; it must not be extrapolated into a post-extraction cleaning-timing instruction.
• F7｜Randomised controlled trial (60 periodontal flap-surgery patients, excluding people smoking more than 20 cigarettes daily): the control group used 0.1% chlorhexidine rinse twice daily for 4 weeks; the test group additionally used a specialised very-soft surgical toothbrush from days 3 to 14 and a soft toothbrush with locally applied chlorhexidine from days 14 to 28, twice daily. Both groups achieved good healing and wound closure at week 4; gingival crevicular-fluid flow did not differ statistically, and the test group had lower incidence of gingival recession of 2 mm or more｜source #1｜confidence=verified｜basis=peer_reviewed (PMID 15491319, randomised controlled trial)｜period=2004｜geo: universal｜span:「Following periodontal flap surgery, 60 patients were randomly assigned to follow one of two post-surgical protocols.」「In addition to CHX rinsing, patients assigned to the test protocol applied CHX locally using a special very soft surgical toothbrush (Chirugia) from days 3 to 14, and a soft toothbrush (Ultrasuave) from days 14 to 28, twice daily.」「Both post-surgical protocols resulted in successful wound healing and optimal wound closure at 4 weeks.」「There was a lower incidence of recession of > or =2 mm following the test protocol.」｜caveat: periodontal flap surgery, not an extraction socket; both groups also used chlorhexidine, so the independent effect of brushing cannot be separated. This card uses its timing of mechanical-cleaning introduction on day 3 as an understanding framework, not as post-extraction timing advice; chlorhexidine is within clinician-prescribing scope, and the card recommends no product.
• F8｜Randomised controlled study (30 patients with chronic periodontitis undergoing osseous resective surgery): the test group (15 people) cleaned the surgical area with a sonic toothbrush from the day after surgery and also used 0.12% chlorhexidine rinse; the control group (15 people) used only 0.12% chlorhexidine rinse and resumed manual brushing only on day 14. The test group had lower (better) early wound-healing indices, more plaque reduction, and milder inflammatory response on days 7, 14, and 28 (P < 0.01); IL-1β and IL-8 were significantly lower on day 14; pain intensity was similar between groups｜source #2｜confidence=verified｜basis=peer_reviewed (PMID 30892797, randomised controlled study)｜period=2019｜geo: universal｜span:「A total of 30 chronic periodontitis patients scheduled for osseous resective surgery with fibre retention technique were randomly assigned to follow one of two post-surgical protocols.」「Patients assigned to the test protocol (n = 15) were instructed to brush the surgical area with a sonic toothbrush starting the day after surgery in addition to 0.12% chlorhexidine (CHX) rinsing, while patients following the control protocol (n = 15) rinsed only with 0.12% CHX solution and resumed mechanical cleansing with a manual toothbrush on day 14 after surgery.」「Lower early wound healing scores, higher bacterial plaque reduction and milder inflammatory response were observed at the surgical sites in the test group on day 7, 14 and 28 when compared to the control group (P < 0.01).」「The intensity of pain was similar between groups.」「The introduction of sonic toothbrush on the first post-operative day as an adjunct of daily CHX rinsing would seem to accelerate early wound healing.」｜caveat: periodontal osseous resective surgery, not an extraction socket; sample 30, single centre; the test group also used chlorhexidine and the authors used the wording “would seem to.” This card must not be used to recommend any powered or sonic toothbrush product or extrapolated into immediate brushing of an extraction wound.
• F9｜Randomised clinical trial (60 healthy participants, each with at least one Miller Class I or II gingival recession, undergoing root-coverage surgery): the control group received a soft manual toothbrush and the test group a soft-head oscillating-rotating powered toothbrush, followed to 6 months postoperatively. Periodontal clinical indices fell more in the powered-toothbrush group (full-mouth plaque score P = 0.05, full-mouth bleeding score P = 0.005, recession depth P = 0.004); the authors concluded that a soft-head oscillating-rotating powered toothbrush resulted in greater gingival-margin stability｜source #4｜confidence=verified｜basis=peer_reviewed (PMID 27677810, randomised clinical trial)｜period=2016｜geo: universal｜span:「Sixty healthy individuals with at least one Miller Class I or II gingival recession underwent a surgical root coverage procedure.」「Use of a powered toothbrush resulted in a significantly greater reduction of recorded periodontal clinical indices compared with a manual device (FMPS, P = 0.05; FMBS, P = 0.005; RD, P = 0.004).」「Soft-bristle manual and powered toothbrushes were given to participants randomly assigned to control and test groups, respectively.」「Use of an oscillating-rotating powered toothbrush with a soft-bristle head resulted in higher GM stability after root coverage procedures compared with the use of a manual soft-bristled toothbrush.」｜caveat: mucogingival plastic (root-coverage) surgery, not an extraction socket; both groups used soft bristles. This card cites it only to show that postoperative studies used soft-bristle devices; it does not recommend a brand, model, or purchase.
• F10｜Randomised crossover trial (23 adults, each undertaking 3 regimens once with 1-week washout periods): after brushing for 1 minute with 1 g sodium-fluoride toothpaste containing 1,450 microg fluoride/g, they rinsed with water for 5 seconds, fluoridated mouthwash for 30 seconds, or non-fluoridated mouthwash for 30 seconds. The salivary fluoride clearance-curve area in regimens A and B was significantly greater than in C (p < 0.001); authors concluded that non-fluoridated mouthwash after brushing may reduce anticaries protection from fluoride toothpaste｜source #5｜confidence=verified｜basis=peer_reviewed (PMID 19776570, randomised controlled crossover trial)｜period=2009｜geo: universal｜span:「Twenty-three adults applied each treatment once in a randomised order, separated by 1-week washout periods, and used a non-fluoridated toothpaste at home prior to and during the study.」「In this supervised, single-blind study, 3 regimes were compared: (A) brushing for 1 min with 1 g of 1,450 microg F/g NaF toothpaste followed by rinsing for 5 s with 10 ml water; (B) as A but followed by rinsing for 30 s with 20 ml of 100 mg F/l NaF mouthwash, and (C) as B but rinsing for 30 s with a non-fluoridated mouthwash.」「The values for regimes A and B were statistically significantly greater than that for regime C (p < 0.001; paired t test).」「These findings suggest that use of a non-F mouthwash after toothbrushing with a F toothpaste may reduce the anticaries protection provided by toothbrushing with a F toothpaste alone.」｜caveat: endpoint was salivary fluoride concentration, not caries incidence; sample 23 and not a postoperative population; authors expressed possibility (“may reduce”). This card cites it as a mechanistic reason to separate brushing and rinsing, not to claim effectiveness.
• F11｜Cochrane systematic review (49 trials, 6,771 participants): dry socket is an extraction complication more often involving mandibular molars; 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｜source #6｜confidence=verified｜basis=peer_reviewed (PMID 36156769, Cochrane systematic review)｜period=2022 (searched to 2021-09-28)｜geo: universal｜span:「We included 49 trials with 6771 participants」「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: same anchor as card #1 F9 and card #4 F6; version check 2026-08-06: PubMed search for CD006968 returned only 2 versions (2012 PMID 23235637 and 2022 PMID 36156769), and this is the current version; pubtype contains no Retracted Publication. This is a background-description passage, not a self-diagnosis tool. Chlorhexidine-related results are in card #1 and F26; this card makes no medication recommendation.
• F12｜Clinical study (surgical removal of 190 impacted mandibular third molars; preoperative hygiene assessed with the Simplified Oral Hygiene Index, and pain and inflammation recorded at 2, 6, and 12 hours postoperatively and daily thereafter through day 7): peak pain was at 6 hours after surgery and peak inflammation at 24 hours; participants with poorer oral hygiene reported higher pain throughout the postoperative period and used more analgesics in the first 48 hours; oral hygiene showed no effect on limited opening or inflammation. Authors concluded that poorer preoperative oral hygiene was associated with greater postoperative pain｜source #7｜confidence=verified｜basis=peer_reviewed (PMID 11552141, prospective clinical study)｜period=2001｜geo: universal｜span:「Maximum postoperative pain was recorded 6 hours after extraction, with peak inflammation after 24 hours.」「The patients with the poorest oral hygiene reported higher pain levels throughout the postoperative period and more analgesic consumption in the first 48 hours. In contrast, oral hygiene appeared to exert no influence on either trismus or inflammation.」「Poor oral hygiene before the surgical removal of 190 impacted lower third molars is correlated with greater postoperative pain.」｜caveat: it measured preoperative oral-hygiene status, not postoperative brushing behaviour; an observational association that must not be read backwards as causation; 2001 single-centre study.
• F13｜Cochrane systematic review (62 trials, 4,643 participants): mandibular wisdom-tooth surgery commonly involves short-term postoperative pain, swelling, and trismus; less frequent events may include infection, dry socket, and trigeminal nerve injuries｜source #8｜confidence=verified｜basis=peer_reviewed (PMID 32712962, Cochrane systematic review)｜period=2020 (searched to 2019-07-08)｜geo: universal｜span:「We included 62 trials with 4643 participants.」「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: same anchor as card #4 F22; background-description passage; this card does not cite its surgical-technique comparison findings; pubtype checked 2026-08-06, no Retracted Publication.
• F14｜Retrospective study (1,821 extractions, including simple and complex extractions, at a university dental outpatient service over 6 years): postoperative infection occurred in 25 cases (1.4%); in binary logistic regression, extraction complexity was statistically significant (OR = 2.03, p = 0.004), and more complex extractions had higher infection rates; other variables such as antibiotic prescribing were not significant｜source #9｜confidence=verified｜basis=peer_reviewed (PMID 34211554, retrospective study)｜period=2021｜geo: universal｜span:「A total of 1821 extractions, including simple and complex extractions, were performed over 6 years. Only 25 (1.4%) of the cases were reported to have a postoperative infection.」「The complexity of the extraction was the only variable that significantly affected the occurrence of postoperative infection after extraction; more complex extractions were reported with higher rates of infection (binary logistic regression, OR = 2.03, p = 0.004).」｜caveat: retrospective, a single university dental outpatient clinic (Malaysia), and not randomly assigned; infection definition was based on clinical records. The study's antibiotic conclusion is a study-level finding; this card makes no medication recommendation.
• F15｜Retrospective analysis (339 outpatient patients with removal of a single third molar, 2016–2018, without prophylactic antibiotics): perioperative complications occurred in 51 cases (15.0%), including acute inflammation of surrounding tissues in 31 patients, limited opening after mandibular wisdom-tooth removal in 13, oroantral communication after maxillary wisdom-tooth removal in 5, and haematoma and transient lingual-nerve sensory change in 1 each; authors concluded that lower third molars and surgical extraction requiring root separation are postoperative-complication risk factors｜source #10｜confidence=verified｜basis=peer_reviewed (PMID 33789003, retrospective study)｜period=2021｜geo: universal｜span:「A retrospective analysis of the medical records of 339 patients treated in the outpatient setting was performed.」「Perioperative complications occurred in 51 (15.0%) cases, and comprised the acute inflammation of the surrounding tissues in 31 patients」「Lower third molars and the necessity of surgical extraction with root separation are risk factors for postoperative complications in patients who require wisdom tooth removal.」｜caveat: retrospective, single centre (Poland), excluding simultaneous multiple extractions, comorbidities, and pregnancy; its definition of complications differs from F14's infection definition, and the two must not be converted into or added to one another.
• F16｜Systematic review (15 included articles): interrupting antithrombotic medication before tooth removal because of fear of bleeding, or after postoperative bleeding, increases the risk of thromboembolic events; local haemostatic measures reviewed included gauze pressure｜source #11｜confidence=verified｜basis=peer_reviewed (PMID 30155575, systematic review)｜period=2019｜geo: universal｜span:「In total, 15 articles were included.」「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: same anchor as card #1 F20 and card #4 F18; this card cites only the risk of stopping medication and recommends no haemostatic material or medicine; whether to interrupt medication is always determined by a clinician.
• F17｜Randomised single-blind controlled trial (35 enrolled and 30 completed; participants had a mesio-angular impacted mandibular third molar, probing depth greater than 5 mm at the distal surface of the adjacent second molar, and crestal radiolucency between the teeth; all had completed oral-hygiene instruction, scaling, and caries stabilisation before surgery): after wisdom-tooth extraction, controls (16 people) had standard socket debridement; the test group (14 people) additionally received ultrasonic root debridement of the second molar before wound closure and a three-visit plaque-control programme. At 6 months after extraction, second-molar distal plaque percentage and probing depth were 21 and 3.2±1.2 mm in the test group, versus 88 and 5.2±0.7 mm in controls (p < 0.007)｜source #12｜confidence=verified｜basis=peer_reviewed (PMID 15966878, randomised single-blind controlled trial)｜period=2005｜geo: universal｜span:「Thirty subjects (50% male, 32.1+/-7.8 years) out of 35 enrolled, with a mesio-angular impacted mandibular third molar, having probing pocket depth (PPD) >5 mm at adjacent second molar distal, and crestal radio-lucency between the two teeth, completed the study.」「Controls (n=16) had their third molar extracted followed by standard socket debridement. Test group subjects (n=14) received the same treatment, except that before wound closure the operator was informed of the group allocation and ultrasonic root debridement on the second molar was performed, followed by a three-visit plaque control programme.」「Six months post-extraction, statistically significantly (p<0.007) better plaque control and shallower probing depths were observed at test second molars' distal (%plaque=21; PPD=3.2+/-1.2 mm) than at control second molars (%plaque=88; PPD=5.2+/-0.7 mm).」｜caveat: the intervention was clinician-performed ultrasonic root debridement plus a three-visit follow-up programme, not patient self-brushing; sample 30 and limited to people whose second molar already had a pocket greater than 5 mm; must not be rewritten as any self-care instruction or brushing-force recommendation.
• F18｜Double-blind crossover trial (10 dental-hygiene students; toothpaste at 5 SLS concentrations from 0.0% to 1.5% was assigned in random order, each applied in an intraoral tray covering attached and unattached upper mucosa for 2 minutes, twice daily, for 4 days per trial period, with a 10-day washout): SLS-free toothpaste caused no reaction, while 1.5% SLS caused desquamation in 60% of participants｜source #13｜confidence=verified｜basis=peer_reviewed (PMID 8451922, double-blind randomised crossover trial)｜period=1993｜geo: universal｜span:「Ten dental hygiene students participated in this double-blind cross-over study.」「The dentifrice without SLS did not result in any onward reaction, whereas the dentifrice containing 1.5% SLS provoked desquamation in 60% of the subjects.」｜caveat: experimental exposure model with a long intraoral-tray contact, not normal toothbrushing; healthy students, not patients after extraction; sample 10 and authors described it as a preliminary study. It must not be used to infer toothpaste safety or harm after extraction.
• F19｜Double-blind crossover trial (20 participants): toothpastes containing 1.2% SLS, 1.2% SLS plus 4% betaine, or 4% betaine alone were placed in a test chamber on buccal mucosa for 15 minutes, with visual and electrical-impedance assessment to 45 minutes. The 2 SLS toothpastes had similar irritating effects on mucosa, while betaine alone showed no significant irritation; betaine did not reduce irritation from the SLS formulation｜source #14｜confidence=verified｜basis=peer_reviewed (PMID 12704946, double-blind crossover trial)｜period=2003｜geo: universal｜span:「Twenty subjects participated in the double blind, crossover study.」「The toothpastes with 1.2% SLS, 1.2% SLS and 4% betaine and with 4% betaine but not with SLS were placed on buccal mucosa in a test chamber and kept in place for 15 min.」「Both SLS-containing pastes had a similar, irritating effect on the mucosa as judged both by the appearance of the mucosa and the EI measurements.」｜caveat: experimental test-chamber contact for 15 minutes, not a toothbrushing setting; sample 20, healthy participants; one author had an industry employment background (Finnfeeds Finland). It must not be extrapolated to an extraction wound.
• F20｜Systematic review and meta-analysis (4 included double-blind randomised crossover trials, 124 people with recurrent aphthous stomatitis, 2 of which entered the main meta-analysis; searched to December 2017; PROSPERO CRD42018086001): compared with SLS-containing toothpaste, SLS-free toothpaste significantly reduced ulcer number, ulcer duration, episode number, and ulcer pain; authors stated that more well-designed trials are still needed｜source #15｜confidence=verified｜basis=peer_reviewed (PMID 30839136, systematic review and meta-analysis)｜period=2019 (searched to 2017-12)｜geo: universal｜span:「Four trials were included in this review (all crossover studies; n = 124 participants) and two contributed to the main meta-analysis based on the random-effect model. SLS-free dentifrice, when compared to SLS-containing statistically significantly, reduced the number of ulcers, duration of ulcer, number of episodes, and ulcer pain.」「However, future well-designed trials are still required to strengthen the current body of evidence.」｜caveat: population was patients with recurrent aphthous stomatitis, not people after extraction; update check 2026-08-06: a PubMed search for sodium lauryl sulfate aphthous, limited to after 2019, returned 8 records; subsequent literature was a 2022 scoping review (PMID 35506963) and primary studies, with no newer systematic review replacing this one. This card must not use it to recommend any toothpaste formulation.
• F21｜Systematic review (11 included studies): meta-analysis found that smokers had more than three-fold increased odds of dry socket, with combined incidence about 13.2% in smokers and about 3.8% in non-smokers｜source #16｜confidence=verified｜basis=peer_reviewed (PMID 35877395, systematic review)｜period=2022 (searched to 2022-03)｜geo: universal｜span:「After meeting the inclusion and exclusion criteria, eleven studies were included in this systematic review (according to the PRISMA statement guidelines).」「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: same anchor as card #1 F10 and card #4 F7; high heterogeneity among included studies and an observational-study aggregate, so this is association rather than causation.

It is cited only for its mechanistic description of the oral environment.
• F26｜Systematic review and meta-analysis (12 included studies in third-molar surgery without concomitant systemic antibiotics): dry-socket incidence was significantly lower in the chlorhexidine group than in controls (9.58% vs. 16.8%, P < 0.0001), with a 42.9% risk reduction｜source #18｜confidence=verified｜basis=peer_reviewed (PMID 42454528, systematic review and meta-analysis)｜period=2026-07｜geo: universal｜span:「Twelve studies were included in the meta-analysis. The incidence of alveolar osteitis (AO) in the chlorhexidine group was significantly lower than that in the control group (9.58% vs. 16.8%, P < 0.0001). Chlorhexidine reduced the risk of AO by 42.9%.」｜caveat: this item is the update-check product for F11 (Cochrane 2022), recording the fact that a newer meta-analysis exists in 2026. The main text does not use its numbers and makes no medication or product recommendation. Indication, concentration, timing, and adverse reactions for chlorhexidine are within dentist or pharmacist prescribing scope; see card #1 for full content. The abstract does not report a 95% confidence interval or heterogeneity metrics; evidence strength requires full-text assessment, which the site did not obtain.

• Same-family division of work (essential reading): for extraction-socket healing-stage timelines, the full definition and return-for-care red flags for dry socket, and full evidence on chlorhexidine and warm salt water, see How Long Does an Extraction Socket Take to Heal? (KM-DENTAL-01). That card covers “how the socket heals”; this card covers “how to clean.” Dry-socket anchor F11 = that card's F9, smoking anchor F21 = that card's F10, haemostasis anchor F16 = that card's F20, and oral-microenvironment anchor F25 = that card's F23; the two cards use the same sources and do not restate the figures [F24].
• Same-family division of work (essential reading): for drinking while anaesthetic persists, same-day dietary restrictions, and item-by-item evidence on straws and hot foods, see When Can I Eat and Drink After a Tooth Extraction? What Should I Eat? (KM-DENTAL-04). That card covers “how to eat and drink.” Rinse-timing guideline anchor F4 = that card's F3; this card cites it only when discussing the order of brushing and rinsing and does not rewrite it [F24].
• Cleaning and eating timing after a filling (a different procedure with different criteria): How Soon Can I Eat or Brush After a Filling? (KM-DENTAL-02)
• How to choose mouthwash and how ingredients differ: How to Choose Mouthwash? Which One for Periodontal Disease? (KM-DENTAL-06)

Publication-gate reminder: this card is a draft. It must not enter km_entries until the 4 language versions (zh-Hans / en / ja) exist. If direct evidence is found later for F23's evidence-gap statement, rewrite that section rather than retaining “not obtained.” The frontmatter's total impressions and site name are internal-audit fields and must not render in the published visible layer.
