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.
