Brief summary

Our aim will be to evaluate the actual efficacy of diode lasers in laser desensitization by comparing the topical gel Emoform Actisens, containing 5% potassium nitrate, alone and in combination with a diode laser. Dental hypersensitivity (DH) will be assessed pre- (T0) and post-treatment (T1) and at 1 month (T2), 3 months (T3), and 6 months (T4).

Detailed description

This will be a randomized clinical trial (RCT) with a split-mouth design, involving 12 subjects, with two parallel groups. The dental elements will be divided into the Trial group, treated with a 980 nm diode laser and desensitizing topical gel, and the Control group, treated only with the same gel. DH will be assessed using the Shiff Air Index (SAI) and Visual Analog Scale (VAS).

Design outcomes

Primary

MeasureTime frameDescription
degree of dentin hypersensitivityFrom enrollment to 6 months after desensitizing procedureassessed using the Dentine Hypersensitivity Experience Questionnaire (DHEQ). The DHEQ is a validated self-report tool designed to assess the impact of dentine hy-persensitivity on a patient's daily life, including the intensity and frequency of symptoms as well as the emotional, social, and practical effects on daily activities such as eating, drinking, and oral hygiene practices. The DHEQ consists of 15 questions, with responses rated on a numerical scale from 1 (strongly disagree) to 7 (strongly agree). The final score is calculated out of a total of 105 points, with higher scores indicating a greater im-pact of dentin sensitivity on daily life.
