RESUMO
AIM: Bernard-Soulier syndrome (BSS) is an inherited bleeding disorder characterized by macroplatelets and thrombocytopenia, prolonged bleeding time, and a prevalence of less than 1 in 1,000,000. In view of the recognition of the risk of bleeding and the management of daily surgical practice in these patients, adequate strategies are necessary to provide the safest care. This article aims to perform an integrative review of the literature on the management of invasive procedures in the oral cavity of individuals with BSS. METHOD: The PubMed/Medline and LILACS databases were searched using Boolean operators related to BSS, bleeding disorders, and oral care. RESULTS: As a result, only five articles with the main theme were included: one letter to the editor and four case reports, described chronologically as to date of publication, classification of the article, and medical/odontological measures taken. CONCLUSION: We conclude with this review the need for adequate knowledge of surgeons regarding coagulation disorders and the need to discuss and plan procedures with the hematology team, as well as the importance of the notion of management of possible complications resulting from invasive treatments in the oral cavity of patients with BSS.

The best-known inherited mild bleeding disorders (MBDs), i.e. type 1 von Willebrand disease (VWD), platelet function disorders (PFDs), and mild to moderate clotting factor deficiencies, are characterized clinically by mucocutaneous bleeding, and, although they are highly prevalent, still pose difficult diagnostic problems. These include establishing the pathological nature of bleeding, and the uncertainties surrounding the clinical relevance of laboratory results. Furthermore, the high frequency of bleeding symptoms in the normal population and the subjective appraisal of symptoms by patients or parents makes elucidating the pathological nature of bleeding difficult. Standardized bleeding assessment tools and semiquantitative bleeding scores (BSs) help to discriminate normal from abnormal bleeding. However, as most MBDs have similar bleeding patterns, for example, bleeding sites, frequency, and severity, BSs are of little help for diagnosing specific diseases. Global tests of primary hemostasis (bleeding time; PFA-100/200) lack sensitivity and, like BSs, are not disease-specific. Problems with the diagnosis of type 1 VWD and PFD include assay standardization, uncertain definition of von Willebrand factor cut-off levels, and the lack of universal diagnostic criteria for PFD. Regarding clotting factor deficiencies, the bleeding thresholds of some coagulation factors, such as factor VII and FXI, are highly variable, and may lead to misinterpretation of the clinical relevance of mild to moderate deficiencies. Remarkably, a large proportion of MBDs remain undiagnosed even after comprehensive and repeated laboratory testing. These are tentatively considered to represent bleeding of undefined cause, with clinical features indistinguishable from those of classical MBD; the pathogenesis of this is probably multifactorial, and unveiling these mechanisms should constitute a fertile source of translational research.
