Parasympathomimetic drugs act on parasympathetic muscarinic receptors to induce an increased saliva flow. The M3 receptor has been identified as the principal target to increase salivary flow rates. [4] Pilocarpine is an example; the maximum dose of this drug is 30 mg/day. Contraindications include many lung conditions, such as asthma, cardiac ...
Radiation therapy for cancers of the head and neck (including brachytherapy for thyroid cancers) where the salivary glands are close to or within the field irradiated is another major cause of xerostomia. [8] A radiation dose of 52 Gy is sufficient to cause severe salivary dysfunction.
Hypersalivation or hypersialosis is the excessive production of saliva. [3] It has also been defined as increased amount of saliva in the mouth, which may also be caused by decreased clearance of saliva.
The risk of systemic infection is higher when the organism has a combined injury, such as a conventional blast, thermal burn, [3] or radiation burn. [2] There is a direct quantitative relationship between the magnitude of the neutropenia that develops after exposure to radiation and the increased risk of developing infection. Because no ...
Head and neck radiation treatment may destroy the cells of the salivary gland which can result in dry mouth. Patients with reduced salivary flow are at an increased risk of tooth decay. The home application of 1.1% fluoride gel with a custom tray is recommended for patients undergoing or are finished with head and neck radiation treatment and ...
Potassium iodide is a chemical compound, medication, and dietary supplement. [4] [5] It is a medication used for treating hyperthyroidism, in radiation emergencies, and for protecting the thyroid gland when certain types of radiopharmaceuticals are used. [6]
This treatment regimen is the same as for all xerostomia patients, such as for those undergoing head and neck radiation therapy, which often damages the salivary glands; these glands are more susceptible to radiation than are other body tissues. [citation needed]
Sialadenitis (sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands. [2]
