Description

The invention relates to medicine, namely to dentistry, and can be used to diagnose a violation of salivary production of the parotid salivary glands.

There is a method of studying the secretory function of the salivary glands using cannulas included in the Afanasyev set, which are introduced into the mouth of the ducts of the large salivary glands and collect saliva. In this case, the cannula is selected individually and saliva is collected in a graduated tube. The study is carried out in the morning on an empty stomach. After oral administration of 8 drops of 1% solution of pilocarpine hydrochloride, the cannula is inserted into the duct of the salivary gland to a depth of 3-5 mm. The end of the cannula is lowered into a graduated tube that the patient holds. Within 20 minutes after the appearance of a drop of secretion (time is noted), it is collected in a test tube and the quantity is determined (Guidelines for Surgical Dentistry and Oral and Maxillofacial Surgery: in 2 volumes. T.1 / Edited by V.M. Bezrukov, T.G. Robustova, Moscow, 2000, pp. 378-379).

The method is time consuming, requires skills in the selection of a cannula for a specific diameter of the duct of the salivary gland, which requires time, collecting saliva is carried out for 20 minutes.

A known method for determining the amount of saliva excreted by non-stimulated and stimulated glands with 2% citric acid solution. Prepare three plastic containers with two cotton rollers in each for collecting saliva. A preliminary weighing of containers with rollers is carried out to further calculate the mass of saliva. A salivation study is performed on an empty stomach or 2 hours after a meal. Install cotton rolls on the bottom of the oral cavity, after a certain time, weigh the cotton rolls soaked in saliva. Get the salivation rate at rest. Then, a salivation rate stimulated by two drops of citric acid is tested. The described method is carried out three times. (Ana Cristina Kfouri Camargo, Daniela Pupo, Ivo Bussoloti filho. Sialometria. ACTA ORL / Tecnicas em Otorrinolaringologia - Vol.23 (3: 14-18,2005)).

The disadvantages of the method are as follows:

1. The inability to differentiate hyposalivation of a particular type of salivary gland (parotid, submandibular, sublingual).

2. Preliminary preparation of the rollers and their weighing.

3. Lack of fixation of the rollers in the oral cavity during diagnosis.

An object of the present invention is to provide a method for the differential collection of saliva from the parotid salivary glands.

The task is achieved by a method of evaluating the secretory function of the salivary glands, including weighing the rollers, installing rollers on the bottom of the oral cavity under the tongue, subsequent weighing of the rollers soaked in saliva, repeating studies three times, calculating the average mass of saliva. Saliva is collected separately from the right and left parotid salivary glands, as well as from the sublingual and submandibular salivary glands for 5 minutes, for which preliminary weighing of the pads is carried out. Mölnlycke Health Care Dry Tips pads are applied with an acute angle to the pterygo-maxillary fold, with a capillary absorption surface to the cheek mucosa, so that the mouths of the ducts of the right and left parotid salivary glands are located in the center of the pads. Two Medicom Medicom Healthcare B.V. cotton swabs are installed symmetrically at the bottom of the oral cavity, separately weighing the pads installed on the left and right sides, and weighing the two rollers together.

Novelty of invention

- Separately collect saliva from the left and right parotid glands, as well as from the sublingual and submandibular pairs of salivary glands for 5 minutes. This allows you to evaluate the secretory function of the glands and identify dysfunction of the parotid salivary glands, which is important for the accuracy of the diagnosis of some diseases - Sjogren's disease, and sialadenitis.

- To do this, pre-weigh the “Dry Tips” Mölnlycke Health Care pads. Laying pads, directing with an acute angle to the pterygo-maxillary fold, the capillary absorption surface to the mucosa of the cheek so that the mouth of the duct (most often located with the mouth open at the level of the upper first molar) of the parotid salivary gland is located in the center of the pads.

- At the bottom of the oral cavity, two standard industrially manufactured cotton rolls are symmetrically installed. For example, Medicom Medicom Healthcare B.V. or any others.

- Produce separate weighing of gaskets installed on the left and right sides, and joint weighing of two rollers.

The method allows to obtain the following technical result:

1. Possible assessment of salivary production of each of the parotid salivary glands.

2. Assessment of the contribution to the formation of oral fluid of the sublingual and submandibular salivary glands.

3. Rapid diagnosis of salivation of the parotid salivary glands.

The method is as follows.

A preliminary weighing of the Dry Tips Mölnlycke Health Care pads and rollers on a laboratory balance VLT-150-P is carried out with a measurement accuracy of ± 0.02 g. From 8 a.m. to 10 a.m. without prior breakfast, the patient is placed in the dental chair in a sitting position. With the patient's mouth open, a pad is introduced first from one side and then from the other side by an acute angle to the pterygo-maxillary fold. A gasket is installed with a capillary absorption surface to the cheek mucosa, so that the mouth of the duct is located in the center of the gasket. Cotton rolls are placed on the bottom of the oral cavity under the tongue. After 5 minutes, separate weighing of the pads installed on the left and right sides is carried out, and the two rollers soaked in saliva are weighed together on a high-precision laboratory balance. The described method is carried out three times. Estimate the result by weight, calculating the average mass of saliva, which was obtained from large salivary glands. Evaluate salivary production of each of the parotid salivary glands.

Example 1. Patient O., 45 years old, applied for the purpose of sanitation of the oral cavity and complaints of dryness in the oral cavity. After the inspection, a study of salivation by the proposed method was carried out. We carried out the weighing of gaskets and rollers before installation in the oral cavity. Installed by the proposed method. After 5 minutes, the gaskets were individually weighed, and the rollers together.

Table 1 No. p / p Gaskets. Mass g Rollers. Mass g Left Right one Before research 0.5 0.5 2,4 2 After the first study 1,5 0.7 4.9 3 After the second study 1,2 0.5 4,5 four After the third study 1.4 0.5 4.3 5 Average value 1.37 0.57 4,57

From table 1 it is seen that the salivation rate of the right salivary gland is significantly lower than the left. The total amount of saliva secreted is reduced. The patient was referred for contrast x-ray examination of the parotid salivary glands. Dental diagnosis: partial secondary adentia of the lower jaw, grade III, 1 Kennedy subclass. Preliminary diagnosis of general status: primary Sjogren's syndrome.

Example 2. Patient K., 54 years old. He complained of dry mouth. After the inspection and research of salivation according to the proposed method, a decrease in the rate of salivary production by both parotid salivary glands, as well as sublingual and submandibular salivary glands was revealed.

From the anamnesis - immunosuppression and secondary Sjogren's syndrome. Complete secondary adentia of the upper and lower jaw, class III according to Oxman.

Thus, the method made it possible to quickly and accurately evaluate salivary production of each of the parotid salivary glands. To assess the contribution to the formation of oral fluid of the sublingual and submandibular salivary glands.
