Eligibility
Age
18 Years to 45 Years
Inclusion criteria
Inclusion criteria: Volunteers of both genders; aged between 18 and 45 years; must present at least one premolar and at most eight premolars with cervical dentin hypersensitivity (CDH), with pain measured on the numerical rating scale (NRS) equal to or greater than 4 and with non-carious cervical lesion (NCCL) with a maximum depth of 1mm; volunteers with at least 20 teeth in occlusion
Exclusion criteria
Exclusion criteria: Volunteers with premolars with Cervical Dentin Hypersensitivity - CDH with active carious lesions; or with defective restorations; or with dental tissue loss requiring restorative treatment; or with pulp inflammation; or that serve as support for removable partial dentures or fixed prostheses; individuals undergoing ongoing orthodontic and periodontal treatment; those who report having received desensitizing treatment from a professional in the last six months or using desensitizing toothpaste in the last three months; those who have used anti-inflammatory drugs or analgesics at the time of recruitment; pregnant women or those who are breastfeeding
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Compare the efficacy of three treatments for cervical dentin hypersensitivity (CDH): light-cured resin varnish; low-intensity laser; combination of laser with varnish application. The level of CDH will be determined using the Numeric Rating Scale (NRS), a unidimensional instrument used to assess pain intensity, which is numbered from 0 to 10, with 0 being “no pain” and 10 being “unbearable pain.” During the dental clinical inspection to identify the presence of CDH, participants will be instructed to indicate the level of pain felt at the end of the application of each stimulus (tactile and evaporative), according to the pain scale that will be presented. The pain level will be recorded individually for each tooth of the patient after the application of each stimulus. Subsequently, the arithmetic mean of the pain levels obtained per patient will be calculated when more than one tooth is included for treatment. Pain will be categorized as ‘no pain’ (0), ‘mild pain’ (1 to 3), ‘moderate pain’ (4 to 6), ‘severe pain’ (7 to 9), and ‘unbearable pain’ (10). Pain level assessment will be measured before the interventions and at 7, 30, 90, and 180 days after the treatments | — |

| Measure | Time frame |
|---|---|
| Evaluate the impact on the physical and psychosocial dimensions of daily activities among participants with cervical dentin hypersensitivity, using the shortened and adapted Brazilian version of "The Dentine Hypersensitivity Experience Questionnaire" (DHEQ). The DHEQ-15 will be administered to the volunteers under the supervision of Operator 1 before receiving the interventions and during follow-up visits (at 90 and 180 days) by Operator 2. The shortened version of the DHEQ-15 consists of 15 items, distributed across 5 subscales: restriction, adaptation, social impact, emotional impact, and identity. In the DHEQ-15, responses will be given on a seven-point Likert scale, with responses coded as follows: 1 = ‘strongly disagree’, 2 = ‘disagree’, 3 = ‘somewhat disagree’, 4 = ‘neither agree nor disagree’, 5 = ‘somewhat agree’, 6 = ‘agree’, and 7 = ‘strongly agree’. The total score will be calculated by summing all the scores of the 15 items (1–7 on the Likert scale) per participant, with a possible range from 15 to 105 points. Scores for each of the five subscales will be obtained in the same way. The proportion of impacts will be calculated by the number of impacts each participant agreed with (‘strongly agree’, ‘agree’, ‘somewhat agree’). High scores obtained from the DHEQ-15 will indicate a negative impact on quality of life;Evaluate the extent and depth of non-carious cervical lesions (NCCLs) that will be included for treatment using the Tooth Wear Index (TWI), which classifies NCCLs into codes (0 to 4) according to the loss of contour and depth of wear. Additionally, the teeth included in the study will have their morphology studied and morphometry recorded by intraoral scanning using the CEREC Omnicam equipment (Sirona Dental System, Switzerland). From the obtained three-dimensional virtual models, the measurement tool of the software 3Shape 3D Viewer (3Shape A/S, Denmark) will be used to determine the height extension, shape, and area occupied by the NCCLs prese | — |
