The evaluation of the desensitization effect of a desensitizing agent and desensitizing toothpastes <i>in vitro </i>

Abstract

This study was evaluating how three desensitizing toothpastes used at home influence the effect associated with desensitizing agents after application in the clinic. Fifty dentine disks measure it permeability and 32 dentine disks with similar permeability levels were selected. Following Dental desensitizer treatment, dentine disks were randomly divided into three subgroups (n=10) that received applications of three toothpastes, respectively. The permeability (Lp) of each specimen was measured after each treatment. One specimen was selected from each group for scanning electron microscopy (SEM) observation. After each treatment, the Lp values decreased significantly for each group (p<0.05) and either completely or partially blocked the dentine tubules upon SEM observation. However, no significant differences in Lp values were observed amongst subgroups (p>0.05). After using the Dental desensitizer, Sensodyne, Crest and Colgate desensitizing toothpastes both can continued to reduce the permeability of the dentine disk, and no significant differences were found amongst them.

Evaluation The Efficiency of Nano Seashell, Sodium Fluoride And A Commercially Available Toothpaste On Dentinal Tubules Occlusion After Acid Attack Using Scanning Electron Microscope: In vitro Study.

“…For group 1(No acid challenge); subgroup A received no treatment, subgroups B, C and D were treated with Sodium fluoride (NaF) paste, Nano seashell paste and signal Complete 8 paste respectively. The paste was rubbed on the sample surface using a micro brush for 2 minutes after which they were rinsed with deionized water for 30 seconds and then stored in the container filled with artificial saliva at 37 ֯ C. [29] This treatment procedure was repeated every 12 hours for 14 days [30,31] . The artificial saliva was changed every 24 hours.…”

Evaluation of the Effectiveness on Dentin Hypersensitivity of Sodium Fluoride and a New Desensitizing Agent, Used Alone or in Combination with a Diode Laser: A Clinical Study

“…Other desensitizing agents that act with different mechanisms to control DH pain have been studied, such as a potassium nitrate-based gel that reduces pain by acting on nerve conduction [11,12]. Furthermore, to improve and ensure a longer duration of the pain relief from DH, treatments with desensitizer agents that act with different mechanisms, such as the desensitizing VivaSens ® , were proposed [13][14][15].…”
