CASE REPORT AND DISCUSSION
Patient L.R.M.O., female, 55 years old, sought care reporting intense
dry mouth. The patient reported that she always had the symptom of
xerostomia, but the condition worsened after undergoing psychiatric
treatment with the combination of the drug Fluoxetine Hydrochloride
20mg. The patient was already using the drugs daily: Simvastatin 20mg
and Fenofibrate 200mg. When contacting the Postgraduate Program in
Medicine – Biophotonics, at Nove de Julho University, the patient was
referred to the clinical trial: “Effect of photobiomodulation on flow,
pH and salivary immunoglobulin level in individuals with xerostomia:
controlled clinical trial and randomized”. Etthics Committee - number:
5.305.375
The participant was instructed to swallow before collection and then
instructed not to swallow, allowing the saliva to flow between the lips
(which will be separated) into a test tube (aspirator) connected to a 15
mL Flacon tube positioned close to the mouth (Navazesh,
Christensen,1982). Collection time was 5 minutes. Saliva volume was
measured and salivary flow rate determined (mL/min) (Vieira, 2018). An
aliquot (1 mL) of saliva was immediately transferred to a small tube
(capacity: 5 mL) and a pH meter (Procyon 720 A, Procyon, São Paulo,
Brazil) was used (Garcia, 2009; Vieira, 2018).
During the clinical examination, no oral and/or dental changes were
observed that could compromise the smooth progress of the treatment. A
specific anamnesis was taken and a questionnaire on xerostomia was
administered (Table 1), in which the patient scored 28. The patient was
then selected through a randomizer.org draw for group B.
