Abstract
AbstractIt is well known that hypersensitivity affects patients recently treated with scaling and root planing. Some studies have demonstrated that photobiomodulation (PBM) can alleviate dentinal hypersensitivity by modulating pain. However, to date, there is no established protocol for its application after scaling and root planning. To evaluate tooth hypersensibility after photobiomodulation in sensitive scaling and root planning treated teeth. Study design: Randomized, controlled, double-blind split-mouth clinical trial. Methods: Forty-four 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) and Control Group: Scaling and root planning +FBM simulation. After 7 days of scaling and root planning, all patients will be evaluated for hypersensibility. The cutoff of VAS will be 3. These patients will be included in the study. The primary outcome of the study will be the assessment of dentin hypersensitivity after 7 days of RAR measured with the visual analog scale (VAS). 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.
