Treatment of the Dental Patient with Bleeding Dyscrasias: Etiologies and Management Options for Surgical Success in Practice

Post-procedural bleeding rate and haemostatic treatment use for dental procedures before and after the implementation of a standardized protocol for people with inherited bleeding disorders

INTRODUCTION

Persons with inherited bleeding disorders are at a substantial risk of bleeding following dental procedures.

AIM

To compare the outcomes and use of haemostatic treatment pre- and post-implementation of a standardized protocol for dental procedures at a Hemophilia Treatment Centre.

METHODS

We conducted a retrospective cohort study of outpatient and inpatient dental procedures and maxillofacial surgeries sustained by people with bleeding disorders treated at a comprehensive Hemophilia Treatment Centre (2013-2020), comparing patients' outcomes before and after the introduction of the protocol in 2018. The protocol, built using a multidisciplinary approach, suggested haemostatic treatment based on the invasiveness of the dental procedure and the proposed anaesthesia. Our primary outcome was the rate of procedural bleeding leading to medical or dental reintervention within 10 days. Secondary outcomes included the use of systemic haemostatic treatment and treatment-related adverse effects.

RESULTS

Overall, 137 dental procedures in 95 patients (median age: 29 years; 78% males; 74% haemophilia, 14% von Willebrand disease, 12% other disorders) were included. Seventeen procedural bleedings were reported (12.4%). Procedural bleeding occurred in 14.8% and 8.9% of patients in the control and intervention groups (p = .304). No major bleeding occurred. Tranexamic acid was used more consistently after protocol implementation (72.8% vs. 89.3%, p = .019), while factor concentrates use decreased (65.4% vs. 44.6%, p = .016), and desmopressin use remained constant (46.4% vs. 32.1%, p = .100). No treatment-related adverse effects were reported.

CONCLUSION

The use of a standardized protocol increased the use of tranexamic acid, with a nonstatistically significant reduction in procedural bleeding rate.

Update on the management of anticoagulated and antiaggregated patients in dental practice: Literature review

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.
