Background: The present study aimed to verify the effect of a single application of 3% potassium oxalate gel compared to a placebo gel immediately after subgingival scaling and root planing (SRP) on dentinal hypersensitivity (DH).
Methods: Fifteen patients undergoing periodontal treatment volunteered for this randomized controlled clinical trial. They presented with periodontitis on homologous contralateral canines and premolars, with complaints of dentinal hypersensitivity before periodontal therapy. Immediately after SRP under local anesthesia, the test and placebo agents were randomly applied on the cemento-enamel junction. Evaluation of DH reduction after treatment was self-reported, with assessment made by the patient's indication of how painful each treated. tooth was on a visual analog scale (VAS) at baseline, and 7, 14, and 21 days post-treatment. The results were analyzed by DH percent reduction for each observational moment in relation to baseline, for test and control teeth separately. Mean percent reductions for each group were compared by paired sample t test, with an alpha level of 0.05.
Results: On day 7, percent reduction for the test and control groups was 29.4% and 13.4%, respectively. On day 14 it was 64.6% and 20.5%, and on day 21 it was 81% and 34.7%, respectively. Significant differences between treatments were observed at 14 and 21 days.
Conclusion: It may be concluded that subgingival scaling and root planing followed by a single application of a 3% potassium oxalate gel resulted in a significantly higher reduction of dentinal hypersensitivity at 14 and 21 days, when compared to the placebo.

Background/purpose: Tubular occlusion is an effective method to treat dentin hypersensitivity. This study aimed to determine the effect of a modified methyl methacrylate-p-styrene sulfonic acid copolymer-based gel desensitizer on dentin permeability and tubule occlusion in extracted human premolars.
Materials And Methods: Hydraulic conductance (HC) measurement (n = 50) and scanning electron microscopy (SEM; n = 64) were performed.

Background/purpose: This study assessed the ability of experimental materials consisting of dicalcium silicate (DCS) and tricalcium silicate (TCS) with nanosized particles to form intratubular crystals under phosphate-buffered saline (PBS) and the effect on dentin permeability reduction.
Materials And Methods: By isolating the cervical part of the extracted premolars, 195 specimens were obtained. Two experimental materials (DCS/TCS and TCS) were applied to the dentin surface by brushing and stored in PBS (n = 65).

Objectives: To investigate if photobiomodulation (PBM) can reduce dentin hypersensitivity (DH) through a randomized, controlled, double-blind clinical trial.
Materials And Methods: One hundred and twelve patients experiencing DH after non-surgical scaling and root planing (SRP) were enrolled and divided into the Experimental Group - SRP + PBM (660 nm, 1.061 J/cm²) and the Control Group - SRP + PBM simulation.

The development of laser technology has revolutionized dentistry, offering complementary and alternative approaches to traditional techniques. Lasers have been successfully integrated into various dental procedures, enhancing treatment outcomes and patient care. Several types of lasers can increase the acid resistance of enamel, thus preventing caries.

Objective: To investigate the education, knowledge and behaviour of Italian dentists regarding Silver Diamine Fluoride (SDF).
Methods: A cross-sectional study was conducted from January to December 2022, through an online survey linked to an online continuing medical education (CME) course sent to Italian dentists. A priori power analysis estimated the necessary sample to be 1480 dentists with an anticipated frequency of 50% and a power of 99.
