“…In addition, it was possible obtained from one tooth a number of samples enought for composing each group, experimental and controls, therefore each dentin block was able to be its own control for fi nal analysis. In this study, the mean of occluded tubules of positive and negative group of each samples were similar than previous studies [15,[27][28][29][30], so the results of dentifrices effects were truest results.…”

“…The Calcium Sodium Phosphosilicate (Novamin) produces a form of apatite when in aqueous environment, an effect that is augmented by the presence of smear layer. The Potassium Nitrate, Potassium Citrate, Sodium Monofl uorphosphate, Stronium Clhoride, and Sodium Potassium Phosphosilicate with the use, are deposited inside the dentinal tubules helping to obliterate them [1,3,8,12,13,[22][23][24][25][26][27].…”

“…These results are very similar to those of other studies using desensitizing agents on rat teeth and on human dentin. 7,17 The dentin tubule diameter was smallest in teeth that were brushed with desensitizing toothpastes. These results obtained in the SCT, PCT and PNT groups were probably due to the action of desensitizing, in combination with abrasive agents, resulting in higher number of partially obliterated tubules.…”

The objective of this study was to analyze the effects of toothbrushing with desensitizing toothpastes on dentin permeability and dentinal tubule occlusion. Fifty rats provided two hundred incisor teeth divided into five groups: DW, brushed with distilled water (control); FT, brushed with fluoride toothpaste; SCT, brushed with strontium chloride toothpaste; PCT, brushed with potassium citrate toothpaste; and PNT, brushed with potassium nitrate toothpaste. Cavities were prepared to expose the dentinal tubules, and the incisor teeth were brushed using the experimental agents. After each treatment, Evans blue dye solution was applied to the teeth. Dentin permeability was analyzed using scanning electron microscopy and energy-dispersive X-rays (EDX). There were significant differences (p < 0.0001, ANOVA) among the groups regarding dentin permeability, number of dentinal tubules, diameter of dentinal tubules, and opened tubular area. In the SCT, PCT and PNT groups, opened and partially occluded tubules, deposits, and a few smear layers were observed. In the DW and FT groups, most of the dentinal tubules were open, with no deposits or smear layers on the dentin. EDX revealed peaks of calcium and phosphorus in all of the groups, as well as traces of strontium in the SCT group and of potassium in the PCT and PNT groups. Desensitizing toothpaste decreased dentin permeability, although it produced only partial dentin tubule occlusion.

“…Farmakis et al showed a combined approach of treatment that showed potential to improve the outcome of treatment for dentin hypersensitivity. 40 The authors used a bioglass combined with Nd:YAG laser irradiation and suggested this combined treatment, as was used by the authors of the present study.…”

Objective: The aim of this randomized longitudinal clinical study was to assess different treatment protocols for dentin hypersensitivity with high-power laser, desensitizing agent, and its association between high-power laser and desensitizing agent, for a period of 6 months. Background data: The literature shows a lack of treatment for dentin hypersensitivity, and lasers are contemporary alternatives. Methods: After inclusion and exclusion analysis, volunteers were selected. The lesions were divided into three groups (n = 10): G1, Gluma Desensitizer (Heraeus Kulzer); G2, Nd:YAG Laser (Power Laser TM ST6, Lares ResearchÒ) contact mode, laser protocol of 1.5 W, 10 Hz, and 100 mJ, & 85 J/cm 2 , four irradiations performed, each for 15 sec, in mesiodistal and occluso-apical directions, totaling 60 sec of irradiation with intervals of 10 sec between them; G3, Nd:YAG Laser + Gluma Desensitizer. The level of sensitivity to pain of each volunteer was analyzed by visual analog scale (VAS) using cold air stimuli and exploratory probe 5 min, 1 week, and 1, 3, and 6 months after treatment. Data were collected and subjected to statistical analysis that detected statistically significant differences between the various studied time intervals of treatments ( p > 0.05). Results: For the air stimulus, no significant differences were found for each time interval. For the long-term evaluation, all groups showed statistical differences ( p > 0.05), indicating that for G2 and G3, this difference was statistically significant from the first time of evaluation (post 1), whereas in G1, the difference was significant from the post 2 evaluation (1 week). Comparison among groups using the probe stimulation showed significant differences in pain ( p < 0.001). Only in G1 and G3 did this difference become significant from post 01. Conclusions: All protocols were effective in reducing dentinal hypersensitivity after 6 months of treatment; however, the association of Nd:YAG and Gluma Desensitizer is an effective treatment strategy that has immediate and long-lasting effects.
