Photobiomodulation on the Salivary Glands of Patients With Xerostomia Induced by the Use of Benzodiazepines
A Phase 1/2 study testing Photobiomodulation and Simulation of Photobiomodulation in people with Xerostomia, run by University of Nove de Julho at 1 site in Brazil.
Trial summary
Depression is the most common mental illness and antidepressants are in the first line of treatment of depressed patients. This therapeutic class is inevitably associated with side effects and adverse reactions, xerostomia being a symptom that seems to be transverse to them all. Read more about this study

About this study
Official title: Effect of Photobiomodulation on the Salivary Glands of Patients With Xerostomia and Hyposalivation Induced by the Use of Benzodiazepines - Study Protocol for a Randomized Clinical Trial
Depression is the most common mental illness and antidepressants are in the first line of treatment of depressed patients. This therapeutic class is inevitably associated with side effects and adverse reactions, xerostomia being a symptom that seems to be transverse to them all. Saliva performs multiple functions and plays a vital role in protecting the health of the soft and hard tissues of the oral cavity. Reductions in salivary flow are most often manifested as dry mouth, and this is the subjective complaint called xerostomia. Although xerostomia is the most frequent indication of reduced salivary production, it is not invariably associated with hyposalivation. The user of antidepressant drugs has a number of important systemic and oral complications. Treatment for salivary changes remains unknown, but low-level laser therapy has been shown to be effective in improving salivary flow in patients with xerostomia due to diabetes, Sjogren's syndrome, chemotherapy and radiotherapy for head, neck and lung cancer. This randomized controlled trial aims to evaluate oral symptoms related to salivary gland function and mucosal condition of depressed patients, as well as the effects of photobiomodulation on salivary flow. Sixty patients will be included in the protocol, after signing the Informed Consent Form. They will undergo anamnesis, physical evaluation and oral health self-perception questionnaires and symptoms related to salivary gland function and then will be divided into two groups: Photobiomodulation (PBM) (n=30); will have their larger salivary glands irradiated with Diode laser (808nm, 4J per point, 40s) and placebo (PCB) (n=30), which will be subjected to a simulation, where the application protocol will be repeated, but with the laser off. Previous and post treatment sialometries will be performed to compare saliva volume. Biochemical analysis, in which total protein and calcium will be measured, will also be performed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PhotobiomodulationRadiation
Participants will receive an application of low intensity light directly in the region of the three pairs of salivary glands. The ArGaAl diode laser, DMC 808nm 4J/point equipment will be used. The parameters that will be used are: Laser Diode ArGaAl, DMC, 808nm, 4J per point, continuously and in contact with the irradiated surface, resulting in irradiance of 3571 mW/cm2, distributed as follows: 6 points in each parotid, 2 points in each sublingual (external) and two in each submandibular (internal), totaling 16 extra oral and 4 intra oral, totaling 20 points. The exposure time will be 40s per point, corresponding to 800s per session and 3600s at the end of the four treatment sessions. The radiant exposure will be 142J/cm2.
Simulation of PhotobiomodulationRadiation
The placebo group will have a simulation of the application of the laser, following the same technique as the active group, but with the device turned off. Because it is an infrared light, it is invisible and this will not induce the patient to notice that the device is turned off.
| Study group | Role | What they receive |
|---|---|---|
| Photobiomodulation group | Active comparator | Participants in this group will have their larger salivary glands irradiated with diode laser. Receives: Radiation: Photobiomodulation |
| Placebo group | Placebo comparator | Participants in this group will be subjected to a simulation, where the application protocol will be repeated, but with the laser turned off. Receives: Radiation: Simulation of Photobiomodulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline Sialometry (measurement of the amount of produced saliva before and after treatment)
The patient will be instructed to keep the head forward allowing all saliva to passively pass through the collection tube, resting on the lower lip, for five minutes. In the last second, the patient will be instructed to spit out all the accumulated saliva in the collection tube. The amount of saliva and foam will be evaluated and properly recorded. Then, the dimethicone (removal of the air bubbles) will be used to obtain the final result. At the end of the photobiomodulation session, a sample of saliva will be collected to be compared to the initial sample. The measurement will be made as follows: milliliters of saliva produced per minute. For stimulate sialometry, a sialogogue will be used. The quantity will be classified as follows: Production of normal saliva: 1.5 to 3.0 ml/minute; Light hyposalivation: from 1.05 to 1.45 ml/minute; Moderate hyposalivation: 0.55 to 1.0 ml/minute; Severe hyposalivation: from 0.05 to 0.50 ml/minute; Sialorrhea: above 3.0 ml/min.
Measured: Baseline and immediately after treatment.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Photobiomodulation and Simulation of Photobiomodulation in people with Xerostomia, run by University of Nove de Julho at 1 site in Brazil.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 5 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Sandra K Bussadori, PhD (+55 11 2633-9000, sandra.skb@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline Sialometry (measurement of the amount of produced saliva before and after treatment) (time frame: Baseline and immediately after treatment.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jul 2022.
