Patients benefit from 3 sessions of auriculotherapy with semi-permanent needles on the 6 points according to the "protocol of Alimi" at one month intervals.

Patients are treated according to the same scheme as the experimental group but with semi-permanent needles positioned on non-specific points.

3 sessions of auriculotherapy with semi-permanent needles on the 6 points according to the "protocol of Alimi" at one month intervals.

Show that auriculotherapy (treatment of specific points) is effective in the treatment of xerostomia compared to a "sham" treatment (treatment of non-specific points).

The relative variation of salivary secretion "after treatment" compared to "before treatment" will be judged on the weight of 3 compresses left 5 minutes in the mouth: 2 in front of the openings of Sténon's canal and 1 on the buccal floor (orifice of Wharton's canal).

Salivary secretion is measured by the weight in grams of the compresses left in the mouth.

This measurement is performed at inclusion and after 3 months of treatment. The measurement is made with a jeweler-type precision balance.

Specific xerostomia questionnaire at inclusion and 3 months post-treatment (11 questions with 5 response levels (1 = never / 2 = very rarely / 3 = occasionally / 4 = quite often / 5 = very often) to evaluate Xerostomia symptoms).
