Evaluation of Tooth Sensitivity After Scaling and Root Planing Treated With Photobiomodulation

One hundred twenty patients with dentin sensibility after non-surgical scaling and root planning (SRP) will be randomly included in 2 groups: Experimental Group: SRP+ Photobiomodulation (PBM) (660nm, 100W, area 0,5cm2, 200w/cm2, 30 seconds, 3 J, 6J/cm2. The study's primary outcome will be the assessment of dentinal sensitivity after 7 days of RAR measured with the visual analog scale (VAS). The cutoff of VAS is 3. The impact of oral health on the participant's quality of life will also be assessed with the OHIP-14 questionnaire. Analgesics (paracetamol) will be prescribed as needed, and the amount of medication will be calculated. These outcomes will be evaluated after 7 days and 1 month of application

About this study

Objective: To evaluate tooth sensitivity after photobiomodulation in sensitive scaling and root planning treated teeth. Study design: Randomized, controlled, double-blind split-mouth clinical trial. Methods: One hundred twenty patients with dentin sensibility after non-surgical scaling and root planning (SRP) will be randomly included in 2 groups: Experimental Group: SRP+ Photobiomodulation (PBM). The dosimetric parameters for the treatment included a wavelength of 660 nm applied in continuous mode with a radiant power of 100 mW (0.1 W). The irradiance ranged from 35.385 mW/cm² to 35 W/cm², with a beam area of 0.002826 cm². Each point received an exposure time of 30 seconds, resulting in a radiant exposure of 1.061 J/cm² and a total radiant energy of 3 J. The procedure involved six irradiated points per tooth, distributed across the vestibular surface (apical, middle, and cervical regions) and the palatal surface. The application technique was performed in contact, maintaining a 90-degree angle to the surface. The treatment consisted of a single session.The primary outcome of the study will be the assessment of dentinal sensitivity after 7 days of RAR measured with the visual analog scale (VAS). The cutoff of VAS is 3. Also, it will be assessed the impact of oral health on the participant's quality of life, with the OHIP-14 questionnaire. The use of analgesics (paracetamol) will be prescribed as needed and the amount of medication will be calculated. These outcomes will be evaluated after 7 days and 1 month of application. If the data are normal, they will be submitted to the ANOVA test - one way. Data will be presented as means ± SD and the p-value will be set to < 0.05.

Treatment and study plan

Photobiomodulation

Device

120 patients with dentin sensibility after non-surgical scaling and root planning (SRP) will be randomly included in 2 groups: Experimental Group: SRP+ Photobiomodulation (PBM) The dosimetric parameters for the treatment included a wavelength of 660 nm applied in continuous mode with a radiant power of 100 mW (0.1 W). The irradiance ranged from 35.385 mW/cm² to 35 W/cm², with a beam area of 0.002826 cm².

The application technique was performed in contact, maintaining a 90-degree angle to the surface. The treatment consisted of a single session.

simulation of Photobiomodulation

Device

Simulation of the use of FBM will be carried out identically to the Experimental group. The person responsible for applying the FBM will simulate irradiation by positioning the devices in the same locations described for the FBM group, however, the laser pointer will be turned off and the sound of the device will be recorded to mimic the use of the equipment and the participant will not identify the group to be used. who belongs. In this trial, we have no criteria for discontinuing or modifying allocated interventions because no harm is expected with this intervention.

Primary outcomes

  1. Pain (VAS) in baseline

    Time frame: baseline

    It will be evaluated through the application of the Visual Analog Scale (VAS) in which we will have a ruler with a length of 10 cm, without markings. One of the extremes is marked "0", and the other "100" which means respectively "no pain" and "unbearable pain".

    This ruler will be the same for all participants (a plasticized ruler where the patient marks with a permanent pen the amount of pain felt at that moment and this amount is measured in millimeters and the value noted in the patient's chart). Instructions on marking will always be given to the patient by the same operator. Each patient will be instructed to mark with a vertical line the point that best corresponds to the intensity of pain at the time of assessment . Without the presence of the patient, the operator will always measure with the same ruler, recording this data on the cards. This analysis will occur on all queries.

  2. Pain (VAS) in 7 days

    Time frame: 7 days after treatment

    It will be evaluated through the application of the Visual Analog Scale (VAS) in which we will have a ruler with a length of 10 cm, without markings. One of the extremes is marked "0", and the other "100" which means respectively "no pain" and "unbearable pain".

  3. Pain (VAS) in 30 days

    Time frame: 30 days after treatment

    It will be evaluated through the application of the Visual Analog Scale (VAS) in which we will have a ruler with a length of 10 cm, without markings. One of the extremes is marked "0", and the other "100" which means respectively "no pain" and "unbearable pain".

Secondary outcomes

  1. Rescue medication at baseline

    Time frame: baseline

    Another parameter analyzed will be the number of analgesics ingested. At the beginning of the research, a pack of paracetamol® will be given to each participant , and use will be performed in case of pain. At the end of the experiment, the number of pills will be evaluated as another pain measurement parameter (drug tablet return). A procedure will be carried out to monitor the adherence of the participants (e.g., all patients will be asked to take the pack of analgesics to the consultation to check how they are being used).

  2. Rescue medication at 7 days

    Time frame: 7 days after treatment

    Another parameter analyzed will be the number of analgesics ingested. At the beginning of the research, a pack of paracetamol® will be given to each participant , and use will be performed in case of pain. At the end of the experiment, the number of pills will be evaluated as another pain measurement parameter (drug tablet return).
