RESUMEN
Background: There have been no reports of sepsis-induced agranulocytosis causing gingival necrosis in otherwise medically healthy patients to the authors' best knowledge. Even though there are several case reports of gingival necrosis secondary to medication-induced agranulocytosis, they have not systematically described the natural progression of agranulocytosis-related gingival necrosis. Methods: This paper presents a case report of a 29-year-old female Indian patient with generalised gingival necrosis and constitutive signs of intermittent fever, nausea, and vomiting. She also complained of abdominal pains. Blood counts showed agranulocytosis, and the patient was admitted for a workup of the underlying cause. Parenteral broad-spectrum antibiotics were administered, which brought about clinical resolution. Results: Her gingival necrosis was attributed to sepsis-induced agranulocytosis triggered by Pseudomonas aeruginosa bacteraemia, and upon clinical recovery, spontaneous exfoliation left behind exposed bone. Secondary healing over the exposed alveolar bone was noted after a year-long follow-up, albeit with some residual gingival recession. Conclusions: Oral manifestations of gingival necrosis, when present with concomitant constitutive symptoms, could indicate a serious underlying systemic condition that could be potentially life-threatening if left untreated. Dentists should be cognizant of this possibility so that timely intervention is not delayed.
RESUMEN
The resultant anemia in hemoglobinopathies like thalassemia can lead to expansion of the bone marrow cavities due to compensatory hyperplasia. This article reports a case of spontaneous osteonecrosis of the left maxillary alveolus in a patient with ß-Thalassemia intermedia. The area affected presented as areas of osteosclerosis on the radiographic examination and sequestrectomy of the left maxillary alveolus was performed after consultation with his hematologist. The exact pathogenesis for the osteonecrosis is unclear. One possible postulation for the cause of osteonecrosis in our case could be that the alveolar bone suffered ischemic infarction secondary to occlusion of the microvasculature within the expanded cancellous bone.

OBJECTIVES: Dual Anti-platelet Therapy (DAPT) are prescribed to patients who had or are at risk of cerebrovascular or cardiovascular ischemic events. This umbrella review appraises existing systematic reviews on the risk of bleeding related complications during and after dental extractions for patients on DAPT. STUDY DATA AND SOURCES: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered to the PROSPERO (International prospective register of systematic reviews) database. A systematic electronic literature search was conducted according to the PRISMA guidelines, via PubMed, Ovid, Cochrane and Embase. STUDY SELECTION: Four systematic reviews met the inclusion criteria and were included the analysis. They show DAPT increases the risk of bleeding related complications after dental extractions, but the differences may not be clinically significant as local haemostatic measures were adequate in controlling bleeding. CONCLUSION: Despite the increased risk of bleeding after dental extractions in patients on DAPT, it may not be necessary to interrupt the anti-platelet therapy. Local haemostatic agents may be sufficient in controlling both the primary or secondary bleeding. On the other hand, the complications of discontinuing DAPT may be more severe and fatal.
