Adverse reactions to medications are common and may have a variety of clinical presentations in the oral cavity. Targeted therapies and the new biologic agents have revolutionized the treatment of cancers, autoimmune diseases, and inflammatory and rheumatologic diseases but have also been associated with adverse events in the oral cavity. Some examples include osteonecrosis, seen with not only bisphosphonates but also antiangiogenic agents, and the distinctive ulcers caused by mammalian target of rapamycin inhibitors. As newer therapeutic agents are approved, it is likely that more adverse drug events will be encountered. This review describes the most common clinical presentations of oral mucosal reactions to medications, namely, xerostomia, lichenoid reactions, ulcers, bullous disorders, pigmentation, fibrovascular hyperplasia, white lesions, dysesthesia, osteonecrosis, infection, angioedema, and malignancy. Oral health care providers should be familiar with such events, as they will encounter them in their practice.
The oral cavity is one of the sites most frequently affected by chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic cell transplantation (alloHCT) and can be a significant source of patient morbidity due to both mucosal and salivary gland involvement. The development of dental decay is a potentially devastating oral complication that has only rarely been reported in the transplantation literature. The purpose of this study was to comprehensively characterize a cohort of patients with cGVHD who subsequently developed extensive dental caries. A retrospective case-record review was conducted for patients who had undergone alloHCT at Dana-Farber/Brigham and Women's Cancer Center between 1990 and 2010 and developed cGVHD-associated rampant dental decay. All patients underwent dental evaluation, involving soft and hard tissue examination and dental radiography, before and after alloHCT. Any dental caries diagnosed at the pre-alloHCT evaluation were treated definitively, such that all patients were considered free of caries at the time of admission for alloHCT. A total of 21 patients were identified, with a median time of cGVHD onset of 5.4 months (range, 2.2-18.5 months) after alloHCT. All patients were diagnosed with oral cGVHD, with 90% demonstrating mucosal involvement and 95% demonstrating salivary gland involvement. Post-alloHCT dental evaluation was performed at a median of 22 months (range, 4-81) after alloHCT, when 10 patients were diagnosed with gross caries and 8 patients had 4 or more affected teeth. Cervical and interproximal patterns of dental caries were frequently diagnosed. The proportions of patients with gross caries, one surface caries, and more than one surface caries (classified as 0, 1-3, and ≥4, respectively) were significantly higher after alloHCT than before alloHCT, with at least 50% of patients experiencing an increase. Patients with oral cGVHD who were free of caries at the time of transplantation developed extensive areas of cervical decay at a median of less than 2 years after alloHCT. This is the first comprehensive characterization of this severe late complication of alloHCT and oral cGVHD. Greater awareness by transplantation oncologists and dentists, as well as more aggressive preventive measures, are needed, as are further prospective studies to better elucidate the incidence of this complication, identify risk factors, and evaluate the effectiveness of preventive interventions.
Objective: This systematic review aimed (i) to explore the Patient-Reported Outcome Measures (PROMs) currently used in the oral mucosal disease literature and to report on the type and context of the use of these instruments and (ii) to provide a future direction for PROMs in oral medicine practice and research.
Discovery and implementation of effective interventions for oral mucositis have been difficult. To date, in the U.S. only palifermin (Kepivance) have been approved and its use is currently confined to patients undergoing stem cell transplant, a very small portion of individuals at risk for mucositis. Fortunately, with the identification of a number of mechanistic pathways which underlie the mucositis' pathogenesis, a rich and diverse pipeline of both topical and systemic compounds are in various stages of pre-clinical and clinical development.
These are the first real-time results for disrupted migration and function of macrophagic THP-1 cells in high doses. Low dosages also demonstrated altered macrophage phagocytosis and cell morphology, suggesting a disturbed local immune function in BRONJ pathogenesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
