Bajkin BV, Tadic AJ, Komsic JJ, Vuckovic BA. Risk of dentoalveolar surgery postoperative bleeding in patients taking direct oral anticoagulants and vitamin K antagonists: A prospective observational study. J Craniomaxillofac Surg 2024; 52:772-777. [PMID: 38580558 DOI: 10.1016/j.jcms.2024.03.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 02/21/2024] [Accepted: 03/30/2024] [Indexed: 04/07/2024] Open
Abstract
The aim of this study was to evaluate whether direct oral anticoagulants (DOAC) and vitamin K antagonists (VKA) increase the risk of postoperative bleeding after dentoalveolar surgery. Patients were classified into two groups: one taking DOAC and the other taking VKA with a therapeutic INR range. The control group comprised non-anticoagulated subjects. Participants were matched regarding dentoalveolar procedure. The primary predictor was anticoagulant status. The primary outcome was postoperative bleeding. The DOAC group comprised 77 patients, while the VKA group and control group each consisted of 103 participants. In each group, 103 dentoalveolar surgical procedures were conducted. Postoperative bleeding was recorded in 3/103 (2.9%), 5/103 (4.8%), and 1/103 (0.97%) occasions in the DOAC, VKA, and control groups, respectively, without significant difference (χ2; p = 0.54). The fully adjusted odds ratio for postoperative bleeding was 0.14 (CI 0.01-1.61; p = 0.05) for patients taking DOAC and 0.19 (CI 0.02-1.65; p = 0.285) for those taking VKA compared with non-anticoagulated controls. In conclusion, there was no increase in risk for clinically significant postoperative bleeding after dentoalveolar surgery in patients taking DOAC or VKA compared with non-anticoagulated subjects. Dentoalveolar surgery in patients taking DOAC and VKA can be performed safely without therapy cessation. The study was registered at Clinicaltrials.gov (NCT04505475).

Abstract
Dental procedures can pose a risk of bleeding, and it is not uncommon for dentists to consult prescribing physicians regarding a mutual patient's antiplatelet and anticoagulant medication to prevent excessive bleeding during or after an upcoming procedure. However, there has been a growing controversy in the dental community surrounding the stoppage of these medications prior to dental procedures. Some believe that stopping these medications prior to dental procedures is necessary to reduce the risk of bleeding complications, while others argue that stopping them can increase the risk of stroke or other thromboembolic events. The debate has left many dentists and specialists unsure about the best course of action when it comes to managing bleeding risk during dental procedures.In this article, we will review the antithrombotic medications, indications, mechanism of action, and its effects on the coagulation pathway, laboratory testing and reversal agents. Also, we will explore the controversy surrounding the stoppage of novel anitplatelets (eg,: prasurgrel and ticagrelor), dual-antiplatelets, triple-antiplatelet, vitamin K antagonists (eg,: wafarin, coumadin), and direct oral anticoagulants (eg,: dabigatran, rivaroxaban, xarelto and endoxaban) in dentistry and examine the current evidence and guidelines for managing dental patients undergoing oral surgery.

Abstract
OBJECTIVES To investigate factors influencing postoperative bleeding occurrence after dental extraction in older patients receiving anticoagulation therapy. MATERIALS AND METHODS This retrospective study included patients aged ≥ 65 years receiving one of the following anticoagulants: apixaban, edoxaban, rivaroxaban, and warfarin. Patients who underwent one to multiple tooth extractions in the geriatric dentistry clinic at Tokyo Medical and Dental University Hospital between August 1, 2016, and November 30, 2020, were included. The outcome variable was postoperative bleeding occurrence. Logistic regression analysis was performed with the following ten factors as explanatory variables: age, sex, maximum systolic blood pressure during the extraction, type of local anesthesia, vertical incision, osteotomy, usage of surgical splints, the mesiodistal width of the extracted tooth on a radiograph, use of antiplatelet agents, and history of diabetes requiring medication. RESULTS Among 395 participants (mean age, 82.3 ± 6.5 years) included in this study, 75 patients experienced postoperative bleeding after tooth extraction. Logistic regression analysis revealed that the odds ratios for the vertical incision (18.400, p < 0.001), osteotomy (3.630, p = 0.00558), usage of surgical splints (1.860, p = 0.0395), and the mesiodistal width of the extracted tooth on a radiograph (1.060, p = 0.0261) were statistically significant. CONCLUSIONS For dental extraction in older patients receiving anticoagulants, postoperative bleeding is more likely to occur in patients with vertical incision, osteotomy, and posterior or multiple tooth extractions. CLINICAL RELEVANCE Dentists should consider suturing and adjunctive hemostatic procedures for patients undergoing vertical incision, osteotomy, and multiple tooth extractions while receiving anticoagulation therapy to minimize the risk of postoperative bleeding.

Abstract
OBJECTIVES The aim of this clinical observational study was to assess the efficacy of L-PRF as a hemostatic agent in patients under treatment with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs). MATERIALS AND METHODS Patients under oral anticoagulant therapy (VKA or DOACs) who needed a single simple tooth extraction were enrolled. L-PRF plug was positioned inside the alveolus and secured with non-absorbable sutures. Surgical time, pain-VAS, paracetamol intake, intra-operative, post-operative biological complications, and bleeding events have been registered. RESULTS A total of 112 patients (59 patients for DOAC and 53 for VKA group) were enrolled. Post-operative bleeding was recorded in nine patients (17%) for VKA group and nine patients (15.3%) for DOACs group. None of the patients needed a medical support for managing of bleeding. Seven days after surgery, no cases of post-extractive complications occurred. CONCLUSIONS The use of L-PRF resulted in limited mild late post-operative bleedings without the need of medical intervention. CLINICAL RELEVANCE The use of L-PRF can be adopted for an uneventful post-operative curse in anticoagulated patients without chasing their therapy for single tooth extraction.

Impact of direct oral anticoagulants on bleeding tendency and postoperative complications in oral surgery: a systematic review of controlled studies.

Abstract
OBJECTIVE The recommendations for the management of direct oral anticoagulants (DOACs) in oral surgery are inconsistent. The present review evaluated whether DOACs increase the risk of bleeding during oral surgery and postoperative complications. STUDY DESIGN The patients undergoing oral surgery and receiving a DOAC were compared with the patients receiving a DOAC different from the exposure, a vitamin K antagonist (VKA), or no anticoagulant. Three electronic databases were searched for eligible clinical trials and systematic reviews. The risk of bias was assessed, data were extracted, a meta-analysis was done, and the Grading of Recommendations, Assessment, Development and Evaluations certainty-of-evidence ratings were determined. RESULTS Three clinical trials comparing patients receiving DOAC medication with patients on a VKA were eligible. A meta-analysis of bleeding 7 days postoperatively detected no significant differences between patients continuing DOAC or VKA medication during and after surgery. All of the point estimates favored uninterrupted DOAC over VKA therapy. Tranexamic acid was topically administered to some patients. CONCLUSIONS Based on an interpreted trend among 3 studies with mixed patient populations, the risk of bleeding during the first 7 postoperative days may be lower for patients on uninterrupted DOAC than VKA therapy (⨁⨁⭘⭘), but the effect size of the risk is unclear. 80 of 274 included patients experienced postoperative bleeding.

Risk of post-extraction bleeding with direct oral anticoagulant compared with warfarin: Retrospective cohort study using large scale claims data in Japan. Thromb Res 2023; 222:24-30.

Abstract
INTRODUCTION Comparative safety of direct oral anticoagulants vs. warfarin in patients undergoing tooth extraction remains unclear. We compared the incidence of post-extraction bleeding between patients taking warfarin and those taking direct oral anticoagulants (DOACs) using administrative claims data. MATERIALS AND METHODS We identified outpatients on anticoagulant therapy who underwent permanent tooth extraction between 2015 and 2020 and categorized them into the warfarin and DOAC groups based on medication prescribed within six months prior to tooth extraction. We used the overlap propensity score weighting method to balance the baseline characteristics between the groups and compared the incidence of post-extraction bleeding within seven days after tooth extraction. RESULTS Among 5253 eligible patients, those in the DOAC group (n = 3696) were older and less frequently prescribed antiplatelets than those in the warfarin group (n = 1557). The distribution of tooth extraction type and number of teeth extracted in a single procedure did not differ between the groups. The unadjusted incidences of post-extraction bleeding in the warfarin and DOAC groups were 35 (2.2 %) and 71 (1.9 %), respectively. Moreover, the overlap weighting analysis showed that the adjusted odds ratio of post-extraction bleeding in the DOAC group in comparison with that in the warfarin group was 0.84 (95 % confidence interval, 0.54-1.31). CONCLUSION The incidence of post-extraction bleeding in patients taking DOACs was comparable to that in patients taking warfarin. The findings suggest that dentists and physicians should exercise the same degree of caution when extracting teeth in patients on DOACs and those on warfarin in terms of post-extraction bleeding.

Abstract
OBJECTIVES This article aimed to compare nationwide time trends of oral anticoagulant prescriptions with the time trend of hospitalization for tooth extraction (TE) in Germany from 2006 through 2017. PATIENTS AND METHODS We derived the annual number of hospital admissions for TE from the Nationwide Hospital Referral File of the Federal Bureau of Statistics and defined daily doses (DDD) of prescribed anticoagulants in outpatients from reports of the drug information system of the statutory health insurance. RESULTS From 2005 to 2017, annual oral anticoagulation (OAC) treatment rates increased by 143.7%. In 2017, direct oral anticoagulants (DOACs) represented 57.1% of all OAC treatments. The number of cases hospitalized for TE increased by 28.0 only. From all the cases hospitalized for TE in Germany in 2006, 14.2% had a documented history of long-term use of OACs. This proportion increased to 19.6% in 2017. Age-standardized hospitalization rates for all TE cases with long-term use of OACs increased from 6.6 in 2006 to 10.5 cases per 100,000 person-years in 2014 and remained almost unchanged thereafter. CONCLUSION Our comparison showed that the large increase in OAC treatment rates in general from 2006 to 2017 had only a small impact on hospitalized TE cases with long-term use of OAC which flattens since 2014.

Abstract
Background: The current systematic review aimed to compare bleeding outcomes in dental extraction patients receiving uninterrupted Direct-acting oral anticoagulant (DOAC) or Vitamin K antagonists (VKAs) for various systemic diseases. Methods: PubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar databases were searched for randomized controlled trials, controlled clinical trials, prospective and retrospective cohort studies, and case control studies, conducted on adult patients undergoing dental extraction under uninterrupted DOAC or VKAs therapy and reporting bleeding outcomes. The search was conducted up to March 31, 2021. We pooled data to calculate risk ratios (RR) with 95% confidence intervals (CI) in a random-effects model. Results: Eight studies comparing 539 patients on DOAC therapy and 574 patients on VKAs were included. Meta-analysis indicated a statistically significant lower bleeding risk in patients under DOAC therapy (RR 0.68 95% CI 0.49, 0.95 I2 = 0%). However, on sensitivity analysis, the results were statistically non-significant after exclusion of any of the included studies. On pooled analysis of limited number of studies, we found no statistically significant difference in the risk of bleeding between apixaban (RR 0.85 95% CI 0.45, 1.60 I2 = 0%), rivaroxaban (RR 0.95 95% CI 0.36, 2.48 I2 = 45%), dabigatran (RR 0.49 95% CI 0.19, 1.28 I2 = 5%), edoxaban (RR 0.41 95% CI 0.13, 1.27 I2 = 0%) and VKAs. Conclusion: The results of the first review comparing bleeding outcomes after dental extraction in patients on uninterrupted DOAC or VKA therapy indicates that patients on DOAC may have a reduced risk of hemorrhage. Current evidence is of very low-quality and should be interpreted with caution. Data on individual DOAC is scarce and at this point, the difference in the risk of bleeding between these drugs cannot be elucidated. Further studies with a large sample size shall supplement our conclusion.

Abstract
Background The aim of this prospective study was to investigate the occurrence and severity of postoperative bleeding following dentoalveolar surgery in patients with uninterrupted anticoagulation therapy (AT). Methods Patients receiving AT (vitamin k antagonist (VK), direct oral anticoagulants (DOAC) or antiplatelet therapy (APT) and in need of surgical intervention classified as A, B or C (single or serial tooth extraction, osteotomy, or implant placement) were studied between 2019 and 2021. A healthy, non-anticoagulated cohort (CG) served as a control group. The main outcomes measured were the frequency of postoperative bleeding, the classification of the severity of postoperative bleeding (1a, 1b, 1c, 2, 3), and the correlation with the AT surgical intervention classification. Results In total, 195 patients were included in the study, with 95 patients in the AT group and 100 in the CG. Postoperative bleeding was significant in the AT group vs. the CG (p = 0.000), with a significant correlation with surgical intervention class C (p = 0.013) and the severity class of bleeding 1a (p = 0.044). There was no significant correlation with procedures of type A, B or C for the other postoperative bleeding gradations (1b, 1c, 2 and 3). There was a statistically significant difference in the occurrence of postoperative bleeding events between the DOAC/APT group and the VK group (p = 0.036), but there were no significant differences regarding the other AT agents. Conclusion The continuation of anticoagulation therapy for surgical interventions also seems reasonable for high-risk interventions. Although significantly more postoperative bleeding occurs, the severity of bleeding is low. The perioperative management of anticoagulated patients requires well-coordinated interdisciplinary teamwork and detailed instruction of patients. Clinical trial registration The study is registered (29.03.2021) at the German clinical trial registry (DRKS00024889).

Abstract
Background Oral antiplatelet and anticoagulant drugs are widely used in a large number of patients visiting the dentist, and there has been much controversy over the years towards their clinical management. The aim to carry out a literature review in order to develop an update on dental management in anticoagulated and / or anti aggregated patients, focusing on oral surgery.
Material and Methods A bibliographic search was carried out in PubMed on studies published between January 1, 2018, until December 10, 2020, using the keywords (“antiplatelet” OR “antiplatelets”) AND (“dentistry”), and (“anticoagulant” OR “anticoagulants”) AND (“dentistry”).
Results The number of studies included in this review was 13, and the number of patients among all of them was 3.497 patients under treatment with some type of antithrombotic drug, who underwent different oral surgery treatments.
Conclusions There is a low risk of peri- and postoperative bleeding events during basic oral surgery treatments in antiplatelet or anticoagulated patients, which can be easily managed through the use of local haemostatic measures. Key words:Oral surgery, antiplatelet drugs, anticoagulant drugs, dental treatment.

Bleeding Complications in Anticoagulated and/or Antiplatelet-Treated Patients at the Dental Office: A Retrospective Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18041609. [PMID: 33567762 PMCID: PMC7915452 DOI: 10.3390/ijerph18041609] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/26/2020] [Revised: 02/03/2021] [Accepted: 02/03/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Bleeding complications in patients undergoing antiplatelet and/or anticoagulant therapy have been one of the main concerns in dental practice. Upon the introduction of new antiplatelet and anticoagulant drugs, there is a search for new protocols that respond to a secure treatment. The aim of the present study was to evaluate bleeding complications in anticoagulated and antiplatelet-treated patients after performing simple dental extractions, in a period of 4 years. MATERIAL AND METHODS 147 clinical records of anticoagulated and/or antiplatelet-treated patients undergoing a simple dental extraction over a period of 4 years (October 2015 to September 2019) were studied. Within the sample, 63 patients were antiplatelet-treated, 83 were anticoagulated, and 1 patient was under both therapies. Within the anticoagulated patients, 70 took classic anticoagulants and 14 new oral anticoagulants (NOACs). Quantitative data were studied with arithmetic mean and standard deviation (SD). The chi-square test was used for the qualitative variables. ANOVA tests were used to compare age and anticoagulated or antiplatelet-treated patients. Statistical significance was determined when p < 0.05. RESULTS From the 418 dental extractions performed, five severe bleeding complications took place in three patients (2.11%). From the five events, four were in patients treated with NOACs (1.68%) and one occurred in a patient anticoagulated with acenocoumarol (0.42%; p = 0.003). CONCLUSIONS Considering the results of this retrospective clinical study, we can conclude that bleeding complications in anticoagulated and/or antiplatelet-treated patients after tooth extractions were low, with a higher incidence recorded in patients treated with NOACs, followed by classic anticoagulants, and there were no complications in antiplatelet-treated patients.

Abstract
When undertaking dental extractions in modern dental practice, two of the complications that have the potential to cause most apprehension for clinicians are the risks of osteonecrosis of the jaws and uncontrollable haemorrhage. This is especially the case when treating older patients because of the increased likelihood of co-morbidities and accompanying polypharmacy which can predispose patients to these problems. Specific medications of concern to practitioners in relation to osteonecrosis risk are antiangiogenic and antiresorptive drugs. Patients taking dual antiplatelet therapy and direct oral anticoagulants require consideration in relation to bleeding risk. With these medications coming increasingly to the forefront over recent years, guidance has been developed by organisations such as the Scottish Dental Clinical Effectiveness Programme (SDCEP). Appropriate use of these guideline should ensure that patients felt to be at particular risk of these complications can frequently be safely managed in primary care. This article aims to provide advice on recognising patients at risk, and to discuss how to utilise key messages within published guidelines when making treatment decisions. The overall intent is to help primary care clinicians who are likely to encounter these patients more and more.

Abstract
OBJECTIVES This study aimed to assess and compare postoperative bleeding occurrence after dental extraction in medically compromised elderly patients under anticoagulant therapy. MATERIALS AND METHODS This retrospective study included medically compromised elderly patients aged ≥ 65 years who were taking apixaban, dabigatran, edoxaban, rivaroxaban, or warfarin and had undergone single or multiple dental extractions. The primary outcome measure was postoperative bleeding occurrence, which was defined as oozing or marked hemorrhage from 24 h to 7 days after dental extraction. Postoperative bleeding occurrence was calculated for each anticoagulant and compared using Fisher's exact test, followed by multiple comparisons. RESULTS Two hundred thirty-two patients met the inclusion criteria. The highest postoperative bleeding occurrence was recorded for rivaroxaban (12/37: 32.4%), followed by apixaban (8/44: 18.2%), warfarin (17/98: 17.3%), and edoxaban (2/35: 5.7%). Patients taking dabigatran did not present postoperative bleeding (0/18: 0%). Fisher's exact test, followed by multiple comparison tests, revealed a significant among-anticoagulant difference (p = 0.0095). Postoperative bleeding was significantly higher in patients taking rivaroxaban than in those taking edoxaban or dabigatran (p = 0.03088). CONCLUSIONS Within the limitations of this retrospective study design, these findings suggest that different anticoagulants may affect postoperative bleeding occurrence after dental extraction among medically compromised elderly patients. CLINICAL RELEVANCE Clinicians should carefully consider postoperative bleeding after dental extraction in patients taking anticoagulant therapy, especially rivaroxaban.

Abstract
Patients on anticoagulant therapy for the prevention of cardiovascular accidents present an increased risk of bleeding following dental and oral surgery. Four recently introduced non-vitamin K antagonist oral anticoagulants, namely dabigatran etexilate (direct thrombin inhibitor), rivaroxaban, apixaban, and edoxaban (Xa factor direct inhibitor), are widely spreading for convenience of use compared to the older drug class. Dental management of patients taking these drugs has substantial differences compared to patients on vitamin K antagonist therapy. Anticoagulation is not assessed directly through a hematological test, but indirectly by renal function. The interventions must be scheduled at the time of minimum blood concentration of the drug. Bleeding can occur even after several days following the surgery. The interaction with drugs administered for dental care must be carefully evaluated. The peri-operative diet can influence the risk of bleeding. Local measures favoring coagulation must be adopted. The interventions with higher risk must be divided into multiple less invasive interventions. Although antidotes exist for these drugs, their use does not seem necessary for dental interventions that have been planned optimally. Furthermore, in this review of the literature a decision protocol is proposed for the evaluation of the suspension of the anticoagulant drug before oral surgery. Cessation of any anticoagulant should only be made in consultation with the patient’s general practitioner/cardiologist, who will weigh up the risk of bleeding from the proposed procedure with the risk of thrombosis/stroke in each individual patient.

Abstract
BACKGROUND Quantitative assessment of bleeding in dental extractions is rarely reported in the literature. The assessment of bleeding might provide additional evidence to predict and minimize postoperative outcomes. The aim of this study was to evaluate the pattern of bleeding in individuals taking direct oral anticoagulants (DOACs) submitted to dental extractions. METHODS Intraoperative bleeding was evaluated by using total collected bleeding corrected by absorbance reading (dental bleeding score). To monitoring bleeding episodes from the day of surgery, this cohort was followed up until the seventh postoperative day. RESULTS Forty-five procedures were performed in three comparative groups, patients under DOACs, individuals taking vitamin K antagonists (VKAs) and without anticoagulant therapy. No bleeding events were observed in procedures carried out in individuals of the DOAC group. Additional hemostatic measures were required in two procedures in the VKA group and one in the non-anticoagulated group. The dental bleeding scores obtained for the DOAC and VKA groups were similar. CONCLUSIONS Our data suggest that the DOAC therapy did not result in increased bleeding outcomes in this sample.

Abstract
INTRODUCTION Dental extractions can be safely carried out on patients under vitamin K antagonists (VKAs) therapy, without stopping or changing the dosage, but the international normalized ratio (INR) needs to be monitored on the day of the intervention, showing adequate rates before proceeding. OBJECTIVES This study aims at evaluating INR values, measured before oral surgery procedures, to assess the rate of patients, under VKAs therapy, outside the therapeutic range. MATERIALS AND METHODS A clinical audit was carried out involving patients under VKAs, who needed minor oral surgery procedures, over a period of 18 months. The patient was instructed to not modify or suspend VKAs prior to the intervention. Before surgery, each patient fulfilled a questionnaire on dietary and oral hygiene habits, and a blood sample was collected for INR assessment (cut-off value for surgical procedure ≤3.5). RESULTS One hundred twenty-two patients were enrolled: 69 (56.6%) had an INR value within the established therapeutic range, 53 (43.4%) were out of range. No intra- or postsurgical major bleeding was recorded. CONCLUSIONS INR, measured on the same day of oral surgery, has the potential to prevent bleeding complications by the identification of those patients out of range, who may require adjusting the drug therapeutic dosage.

Abstract
BACKGROUND Conflicting recommendations exist addressing the management of direct oral anticoagulants (DOACs) for invasive dental procedures. OBJECTIVES To determine the safety of DOAC continuation compared to warfarin continuation for dental extractions with regards to bleeding outcomes. METHODS A single-center, prospective, cohort study was performed to compare 7-day bleeding outcomes between patients who continued their DOAC, and patients on warfarin with an International Normalized Ratio (INR) between 2.0 and 4.0. Blood tests including oral anticoagulant drug levels were measured immediately prior to extraction. The gauze used to apply pressure to the socket was weighed before and after extraction to estimate blood loss. Patients were contacted by phone 2 and 7 days after extraction. RESULTS Eighty-six patients on a DOAC had a total of 145 teeth extracted, and 21 patients on warfarin had 50 teeth extracted. There were no major bleeding events. The rate of minor plus clinically relevant nonmajor bleeding was comparable between the DOAC and warfarin cohorts (36% and 43%, respectively; odds ratio, 0.75; 95% confidence interval, 0.29-1.98). Preextraction apixaban and dabigatran levels were comparable between bleeders and nonbleeders, while rivaroxaban levels were higher in those who bled. The weight change of gauze used to tamponade the socket was similar between the 2 cohorts. CONCLUSION Dental extractions on patients continuing DOACs led to bleeding rates similar to patients on warfarin with an INR between 2.0 and 4.0. There is no need to adjust DOAC dosing prior to dental extractions.
