Abstract
BACKGROUND The number of patients treated with coagulation disorders, and more specifically with anticoagulant therapy, has increased worldwide in recent years due to increased life expectancy in developed countries. The protocols for managing this type of patient in oral surgery has varied over recent years, especially after the appearance of new direct-acting oral anticoagulants (DOACs). The assessment of risk of bleeding in this type of patient when undergoing a surgical procedure continues to be a controversial issue for patients, dentists and general practitioners. The objective of this document is to offer recommendations, based on evidence, for decision making for patients with coagulopathies who require dental surgical intervention. MATERIAL AND METHODS Based on the indications of the "Preparation of Clinical Practice guidelines in the National Health System. Methodological manual", we gathered a group of experts who agreed on 15 PICO questions based on managing patients with coagulation disorders in dental surgical procedures, such as fitting of implants or dental extractions. RESULTS The 15 PICO questions were answered based on the available evidence, being limited in most cases due to the lack of a control group. Two of the PICO questions were answered by the experts with a grade C recommendation, while the rest were answered with grade D. CONCLUSIONS The results of this review highlight the need to undertake well designed clinical trials with control groups and with a representative sample size.

The effect of different hemostatic agents following dental extraction in patients under oral antithrombotic therapy: a network meta-analysis. Sci Rep 2023; 13:12519. [PMID: 37532770 PMCID: PMC10397210 DOI: 10.1038/s41598-023-39023-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Accepted: 07/19/2023] [Indexed: 08/04/2023] Open
Abstract
This network meta-analysis was done to thoroughly evaluate the available literature on the use of different hemostatic agents for dental extraction in patients under oral antithrombotic therapy, aiming to identify the agent with the best/worst performance in bleeding control. Considering that such patients have a higher risk of bleeding, choosing the right hemostatic is essential. Twenty-three randomized clinical trials articles were included after completing the literature search. Cyanoacrylate tissue adhesive showed a reduction in the odds of postoperative bleeding events compared with conventional methods (i.e., gauze/cotton pressure, sutures), with a tendency toward a statistical significance (OR 0.03, P = 0.051). Tranexamic acid was the only agent that demonstrated a significantly lower risk of developing postoperative bleeding events (OR 0.27, P = 0.007). Interestingly, chitosan dental dressing and collagen plug had the shortest time to reach hemostasis. However, they ranked last among all hemostatic agents, regarding bleeding events, revealing higher odds than conventional measures. Therefore, it is concluded that the use of cyanoacrylate tissue adhesive and tranexamic acid gives favorable results in reducing postoperative bleeding events following dental extractions. Although chitosan dental dressing and collagen exhibited a faster time to reach hemostasis, they led to a higher occurrence of bleeding events.

J Clin Med 2022; 11:jcm11133654. [PMID: 35806937 PMCID: PMC9267478 DOI: 10.3390/jcm11133654] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 06/08/2022] [Accepted: 06/20/2022] [Indexed: 01/27/2023] Open
Abstract
Background: An adequate blood supply plays a leading role in the healing process of the post-extractive socket; its coagulation leads to fibrin clot formation, which acts as a physical barrier able to prevent postoperative bleeding and microbial infection. The purpose of this study was to evaluate the effectiveness of antiaggregant drugs in healing post-extraction sockets compared to natural wound healing. Methods: This was a single-center prospective clinical trial. Extraction sockets allocated in healthy patients and in patients assuming antiplatelet drugs were considered. Thirty consecutive patients under (treated with/in treatment with) oral antiplatelet treatment were enrolled in the test group. In order to provide a control group, 30 consecutive patients meeting all the exclusion and inclusion criteria were enrolled. The extraction of the mono-radicular tooth was atraumatically performed without gingivoplasty or osteotomy procedures that could influence the healing process. Photographs were obtained before and immediately after surgery and at 3-, 7-, 14- and 28-days follow-up. Results: All patients assumed the prescribed therapy and their post-operative recovery was uneventful without any kind of post-extractive complications. The results of inter-group comparison show that on the third and seventh days of follow-up, the antiplatelet group expressed a statistically significant higher level of healing compared to the control group (p < 0.05), while no statistically significant differences were recorded at 14- and 28-days follow-up. Conclusions: Patients treated with antiplatelet agents seemed to show that this therapy can positively affect the healing process after tooth extractions.

Abstract
OBJECTIVES A wide variety of approaches have been proposed to manage anticoagulant drugs in patients undergoing dental surgery; vitamin K antagonists and novel direct oral anticoagulants have been used. The present study aims to explore the existing evidence concerning the management of patients in anticoagulant therapy undergoing oral surgery procedures and to give suggestions related to peri- and post-operative measures. MATERIALS AND METHODS A comprehensive search of databases was conducted to identify studies that evaluated the relationship between direct oral anticoagulants and dental procedures. The present scoping review was realized in adherence with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. The publications varied from randomized controlled trials (RCT) to cohort trials. Only articles written in English language and published between 2000 to 2020 were screened. The studies were included if discussing the management of a patient in anticoagulant therapy (warfarin or direct oral anticoagulants) scheduled for tooth extraction. RESULTS 33 studies were selected and included in the qualitative review. Nineteen considered anticoagulant therapy with warfarin, six considered anticoagulant therapy with new oral anticoagulants and eight compared patients taking warfarin with patients taking direct oral anticoagulants. CONCLUSIONS No case of extractive surgery should alter the posology of the drug: thromboembolic risks derived from discontinuation are heavier than hemorrhagic risks. CLINICAL RELEVANCE direct oral anticoagulants are safer in terms of bleeding and manageability and bleeding episodes are manageable with local hemostatic measures.

Front Pharmacol 2021; 12:702057. [PMID: 34776943 PMCID: PMC8585494 DOI: 10.3389/fphar.2021.702057] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 10/13/2021] [Indexed: 11/13/2022] Open
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 Due to technology and pharmaceutical science and increasing life expectancy, the patient population is continuously aging. Patients requiring dental extractions often have systemic and/or chronic diseases and are undergoing polypharmacologic therapy. Oral surgeons often interface with patients who perform anticoagulant therapy. The main aim of this study was to clarify what the contraindications and short-/long-term complications may be. METHODS A sample of 298 patients (mean age 58 years) who required multiple surgical dental extractions has been taken in consideration. Patients were divided into groups and subgroups according to the anticoagulant drug therapy. RESULTS Long-term complications represented variable bleeding between groups from 8 hours to 7 days after surgery. The One-Way ANOVA Test was used to compare the results between groups. Patients treated with direct oral anticoagulants showed fewer intraoperative problems, but further studies and further collaboration between doctors, cardiologists and oral dentists/surgeons are certainly needed to manage these patients in a predictable manner. CONCLUSIONS This study showed that using direct oral anticoagulants drugs results in few intraoperative bleeding, less postoperative hemorrhagic complications, and an easier administration of the drugs respect vitamin K antagonists, with mild and manageable complications.

A systematic review with meta-analysis. Clin Oral Investig 2021; 25:3369-3381. [PMID: 33758999 DOI: 10.1007/s00784-021-03882-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 03/10/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE This study aimed to systematically review literature about the effect of alteration of the pharmacological regimen in adult patients using anticoagulants or antiplatelets who need minor oral surgery. MATERIAL AND METHODS A search strategy was performed in three databases-PubMed-Medline, Scopus, and Embase-and included randomized clinical trials (either parallel or crossover), involving individuals under anticoagulant or antiplatelet therapy who underwent oral surgeries. Studies comprised two groups: those who stopped their medication prior to the dental procedure (control) or those who did not (test). Meta-analyses were conducted for the pooled risk ratio (RR) between the groups. Subgroup analyses were performed for anticoagulant and antiplatelet therapies. RESULTS Thirteen studies were included. It was found that patients who did not stop therapy had 157% higher intraoperative bleeding occurrences (95%CI: 1.40-4.71). In the subgroup analysis, warfarinazed patients showed significantly higher occurrences of intraoperative bleeding when compared with the control (RR: 1.79; 95%CI: 1.00-3.21). Conversely, there was no statistically significant difference in postoperative bleeding between the groups (RR: 0.81; 95%CI: 0.54-1.22; p = 0.42). CONCLUSION Minor oral surgeries can be safely performed in patients under antiplatelets or anticoagulants without drug regimen modification. Because these patients tend to bleed more during procedures, use of local hemostatic measures is strongly advised. CLINICAL RELEVANCE Management of patients under antiplatelet or anticoagulant drugs is still challenging in clinical practice. However, clinicians may perform minor oral surgeries safely without changing the pharmacological regimen. Use of local hemostatic measures is strongly advised during these procedures.

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.

Abstract
PURPOSE To evaluate the clinical outcomes of platelet-rich fibrin (PRF) application for hemostasis after dental extraction in patients receiving anticoagulant therapy with factor Xa inhibitors. METHODS In total, 25 patients receiving anticoagulant therapy with rivaroxaban or apixaban who required routine dental extraction were evaluated. In all patients, PRF was used for hemostasis in addition to adapting sutures. Bleeding was subjectively assessed using a sterilize gauze pad at 24, 48, and 72 h after the procedure. RESULTS All invited participants (n = 25) consented to participate. The PRF clots successfully arrested bleeding after extraction in all patients, with no complications at any time point after the procedure. Favorable soft tissue healing was observed during suture removal at 10 days after the procedure in all patients, with no signs of infection or late healing. CONCLUSIONS The results of this case series indicate that PRF is a promising natural hemostatic agent for the management of bleeding after dental extraction in patients receiving factor Xa inhibitor therapy. Further controlled clinical studies with larger patient samples are necessary to clarify the findings of this case series.

Oral surgery to remove pyogenic granuloma in a high-risk patient is reported. A 47-year-old man with gastroesophageal reflux disease, diabetes mellitus II, dyslipidemia, and chronic coronary insufficiency (myocardial infarction within 2 years) with episodes of unstable angina was submitted to an excisional biopsy of hemorrhagic lesion in the lingual right mandibular gingiva. During dental treatment, the arterial blood pressure, oxygen saturation, heart rate, and electrocardiogram were monitored. Local anesthesia was performed with 0.45 ml of 3% prilocaine with 0.03 IU/ml felypressin. The anticoagulant therapy was not interrupted. No local or systemic complications were noticed during or after the surgery.

Abstract
OBJECTIVES The aim of this prospective comparative clinical study was to evaluate the effect of oral anticoagulants on peri- and post-operative bleeding during simple single tooth extractions, comparing patients in treatment with vitamin K antagonists (VKAs) and patients assuming direct oral anticoagulants (DOACs). MATERIALS AND METHODS Patients under oral anticoagulant therapy needing dental extraction were eligible for entering the study; patients were enrolled following inclusion and exclusion criteria and divided into VKAs and DOAC group according to the anticoagulation therapy. Included patients underwent a simple single dental extraction with elevators and forceps with a maximum surgical time of 15 minutes, without anticoagulation therapy discontinuation. All participants were assessed pre-operatively, during surgery, 30 min minutes and 7 days after surgery. Biological complications were registered and post-extraction bleeding was clinically defined according to Iwabuchi classification. Parametric and non-parametric tests were used to evaluate the variables between the groups. RESULTS Sixty-five patients per group were enrolled and 130 teeth were extracted. The two groups were comparable for pre-, peri-, and post-operative variables. Only 1 patient of DOAC group and 2 patients for VKA group needed medical evaluation for post-extractive bleeding. No statistically significant difference resulted in post-operative bleeding events between the groups (p = 0.425). CONCLUSIONS DOAC and VKA patients showed the same incidence of bleeding complications after simple single tooth extraction. Bleeding events were not statistically significant and not clinically relevant. CLINICAL RELEVANCE Patients assuming DOACs can be treated similarly to patients in VKAs therapy with INR index between 2 and 3. Non-ceasing of DOAC therapy seems to be appropriate for simple single dental extractions.

Rai S, Rattan V. Efficacy of Feracrylum as Topical Hemostatic Agent in Therapeutically Anticoagulated Patients Undergoing Dental Extraction: A Comparative Study. J Maxillofac Oral Surg 2018; 18:579-583. [PMID: 31624440 DOI: 10.1007/s12663-018-1156-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Accepted: 09/25/2018] [Indexed: 11/25/2022] Open
Abstract
Aims and Objective To compare the efficacy of feracrylum with tranexamic acid (TXA), following dental extraction in patients who are therapeutically anticoagulated with warfarin. Study Design Sixty patients on warfarin were randomly divided into three groups. Groups 1 and 2 patients were given feracrylum (1%), and TXA (5%) solution pressure pack and a control group (Group 3) was given normal saline (NS) pressure pack after extraction. Postoperative bleeding was assessed and graded numerically and periodically (0, 1, 2, 5 and 7 days). The values were statistically analyzed. Results Sixty patients (M:F::37:23) with a mean age of 56 years who were therapeutically anticoagulated for different medical conditions were included. The mean warfarin dosage was 3.5 mg, and the mean INR was 2.83. Out of 27 patients who showed bleeding on day of extraction, eight, ten and nine patients belonged to groups I, II and III, respectively, and the difference was nonsignificant. Out of 15 patients who showed bleeding on post-extraction day 1, one, five and nine patients belonged to groups I, II and III, respectively. The difference was statistically significant on day 1 and nonsignificant in the next follow-ups. Conclusion Local hemostatic agents like TXA and feracrylum arrest bleeding without having any systemic action and without the necessity of altering the anticoagulant regimen. Feracrylum has an added advantage of a single application, formation of a mechanical barrier and an additional antimicrobial effect. These agents should be incorporated in the protocol for managing patients on oral anticoagulants.
