About this study
Official title: Evaluation of Photobiomodulation in Salivary Production of Patients With Xerostomy Induced by Anti-hypertensive Drugs
Xerostomia is a quantitative and qualitative alteration of saliva, a symptom present in individuals who make continuous use of medications to control chronic diseases, including hypertension. Difficulties in mastication, swallowing, phonation and palate are present, besides oral burning syndrome, periodontal disease, root caries and bad breath that will interfere in the quality of life, making it difficult to socialize in society. Currently, the methods presented for treatment of xerostomia are palliative, so their use does not consist of an effective treatment. The objective of this study is to evaluate the efficacy of photobiomodulation in the production of saliva in patients with xerostomia induced by antihypertensive drugs. The method consists in the application of the low intensity laser in the three pairs of salivary glands - parotid, submandibular and sublingual. 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. The control group will have a simulation of the application of the laser, 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. In the group that receives the photobiomodulation the device will have its timer turned off, to avoid the perception of sound difference. At the end of the sessions, a sample of saliva will be collected, which will be compared to the initial sample.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PhotobiomodulationRadiation
The parameters 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.
ShamRadiation
The sham group will have a simulation of laser application, following the same procedures as the active group, but with the device switched off.
| Study group | Role | What they receive |
|---|---|---|
| Photobiomodulation group | Active comparator | Patients will receive 3 applications of low intensity light directly in the region of the three pairs of salivary glands already described. 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. The first application will be after the stimulated collection of saliva and the following applications will be given once a week for another 2 weeks. Receives: Radiation: Photobiomodulation |
| Sham group | Sham comparator | The placebo group will have a simulation of 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. Receives: Radiation: Sham |
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 sessions 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: One month.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

The record says: status not confirmed, as of the sponsor's last update on 11 Oct 2018. 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 phase mean?
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?

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03632096, which also lists 1 linked publication.
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 11 Oct 2018.
