The advantages and disadvantages of various submandibular saliva collectors that have been described in the literature indicate the need for a simplified, efficient collector for field studies. This paper reports the design, construction, and testing of such a submandibular saliva collector.
The final appliance is V-shaped with a collecting area at the apex and three polyethylene tubes affixed to it, one to each arm and one to the collecting dome. Fabricating material is the most dense room temperature vulcanizing rubber available (RTV-60). The appliance's two arms, which are hollow underneath, are seated alongside the base of the tongue and maintained in position over the salivary ducts by a vacuum in the arms only. This vacuum is supplied by 10-oz. rubber bulbs. The collecting area is not maintained under vacuum; saliva is allowed to flow freely on stimulation by sour lemon candies.
The appliance has been tested on 25 subjects ranging in age from 5 to 32 years; a red-colored, flavored dye was used for saliva stimulation to test the effectiveness of the seal around the collecting area.
The collection of large volumes of pure submandibular saliva by use of this appliance is readily achieved for the great majority of persons. Collection is accomplished with comfort to the patient, no trauma to the soft tissues of the mouth and a minimum of time and effort. The outstanding advantage of the collector is that it is ideal for field studies since it requires no additional apparatus and enables collection of large volumes of saliva.
