Prevention of xerostomia secondary to radiation therapy

Prevention of xerostomia secondary to radiation therapy refers to prophylactic clinical strategies aimed at averting or mitigating salivary gland hypofunction and the subjective sensation of dry mouth in patients receiving ionizing radiation, most notably for head and neck malignancies Ionizing radiation directly damages the secretory acinar cells, microvasculature, and stem cell compartments within major and minor salivary glands, leading to progressive inflammation, oxidative stress, and gland...

Prevention of xerostomia secondary to radiation therapy refers to prophylactic clinical strategies aimed at averting or mitigating salivary gland hypofunction and the subjective sensation of dry mouth in patients receiving ionizing radiation, most notably for head and neck malignancies

Ionizing radiation directly damages the secretory acinar cells, microvasculature, and stem cell compartments within major and minor salivary glands, leading to progressive inflammation, oxidative stress, and glandular fibrosis

Clinically, this impairment results in markedly diminished saliva volume and altered salivary composition, predisposing affected individuals to debilitating complications such as oral mucositis, rampant dental caries, dysphagia, dysgeusia, and opportunistic oral infections

Preventative interventions focus on preserving glandular architecture and baseline secretory capability before irreversible radio-induced destruction occurs
