Severe xerostomia - salivary flow under 0.30 ml/min. (no formation of coating).
Moderated xerostomia - salivary flow from 0.30 to 0.50 ml/min. (with formation of coating).
Light xerostomia - salivary flow from 0.50 to 0.70 ml/min (higher or lower formation of coating).
The patient with salivary flow from 0.85 to 1.0 ml/min can be considered normal, as long as the parotid glands function is good.
The salivary flow from 1.0 to 1.5 ml/min is considered normal.
The Hiperboloide in the Xerostomia:
The Hiperboloide fills a gap as a mastication apparatus. Up to the present moment, there was no instrument with format and hardness, scientifically elaborated for masticatory exercises. In any position of mastication, keeps the jaw in relation, producing pleasant salivary glands excitations bigger and smaller, specially in the parotid and Ebner, responsible for high level of serosa saliva excretion, which, indirectly and at the same time, actuates in the therapeutic field of xerostomia.
It also acts in the dental cavities and tartar prevention, via pH.
Xerostomia is the reduction of the salivary flow, also denominated hypopituitarism (dry mouth). Its etiology is wide. It can be the result of several diseases in the kidneys, liver, pancreas, lungs etc. As a common example, we can mention a non controlled diabetic, with bad breath and dry mouth. The use of medication and its collateral effects speed up the xerostomic process. It is also provoked by psychosomatic dysfunctions caused by psychic conflicts, anxiety, neurosis, angst, depression (stress). It is common among senile adults, due to the progressive atrophy of the glands and the gradual stenosis of its ducts.
Salivary flow test - Sialometry
The salivary flow volume is evaluated through these steps:
• Using a mechanic stimulator which can be the Hiperboloide. The mastication is performed during 5 minutes and the saliva is not swallowed, but it is rather inserted in a collector tube each 20 seconds.
• Verify how many ml of saliva were taken in 5 minutes.
• Divide the result for 5 to deduce the quantity of ml/minute.
Note: In severe xerostomia, under 0.30 ml/min there is no formation of coating, the patient cannot form it due to the low salivary excretion and to the deficient amount of mucin.
