von Willebrand's disease (vWD) is one of the most common hereditary hemorrhagic disorders. A mild to moderate deficiency of factor VIII and von Willebrand factor (vWf) often is associated with gingival bleeding. In this case report, the periodontal treatment of a patient with vWD is described. A 45-year-old woman with type IIA vWD was referred for periodontal therapy because of an episode of gingival hemorrhage and percussion pain of teeth #18 and #47. The periodontal findings included probing depths ranging from 2 to 6 mm, horizontal bone loss, and Class II furcation involvement of tooth #46. After consultation with a hematologist, apically positioned flap surgery and hemisection were performed on tooth #46 following completion of oral hygiene instruction, scaling and root planing, and endodontic therapy. The patient was given 500 units of factor VIII including vWf multimer 30 minutes before surgery. After healing of the periodontal tissue, prosthodontic treatment was undertaken on the posterior mandibular sextants. At follow-up, the probing depths ranged from 2 to 3 mm, and gingival bleeding on probing was minimal. The patient's children all had vWD. They had mild to moderate periodontitis with probing depths ranging from 2 to 5 mm and gingival bleeding on probing. With the combined efforts of the periodontist and hematologist, effective periodontal treatment can be provided to patients with von Willebrand's disease.

We report a 55-year-old patient with type 3 von Willebrand disease who underwent multiple tooth extractions with successful hemostatic management using recombinant factor VIII. The patient was previously misdiagnosed and treated incorrectly then at 53 years old, he was diagnosed with type 3 von Willebrand disease. As he had avoided dental treatments for two decades due to severe bleeding after dental extraction, multiple severe caries and marginal periodontitis were revealed. The patient refused the use of blood products in hemostatic management because he was afraid of blood-borne diseases and development of anti-von Willebrand factor alloantibodies. After close consultation, we therefore decided to use recombinant factor VIII. Four teeth extraction procedures were executed twice. Before extraction, bolus recombinant factor VIII (50 IU/kg) was administered intravenously followed by continuous infusion (5-10 IU/kg per h) for approximately 48 h. The factor VIII:C level increased from about 1 to 20-32% 30 min after bolus infusion. During continuous infusion (10 IU/kg/h), factor VIII:C was maintained at more than 10%. Little bleeding occurred during and after the multiple teeth extractions and during suture removal. On frequent examinations during a 1-year follow-up, neither von Willebrand factor nor factor VIII inhibitors were detected.

Inflammatory disorders of the periodontium, gingivitis and periodontitis are among the most prevalent diseases worldwide. A few studies have found poorer oral health in patients with congenital coagulation disorders (CCD) like haemophilia and von Willebrand's disease compared with non-affected controls. The aim of this study was to investigate the effect of congenital coagulation disorders on oral health and periodontal (alveolar) bone loss. This is a case control study comparing oral health and periodontal bone loss of patient with congenital coagulation disorders with matched healthy subjects. The examination included dental status (DMF-T), assessment of oral hygiene (modified Quigley-Hein-Index: QHI) and a dental panoramic X-ray for assessment of alveolar bone loss caused by periodontal disease. A total of 15 patients with CCD (Haemophilia A: n = 8, von Willebrand's disease: n =7) were matched with 31 non-affected controls. We observed no clinical relevant difference of oral health (DMF-T, QHI) between patients with CCD and controls despite better oral hygiene (QHI) of patients with CCD. Moreover, there was a statistically significant difference in periodontal bone loss, but the observed difference is not clinically meaningful. Unlike previous studies carried out mainly in children we found no evidence that oral health or periodontal status in adult patients with CCD is worse than that in healthy subjects. However, larger studies and longitudinal studies in adults are needed to confirm our results.
