Brief Summary

Here's the revised version with the corrected treatment and follow-up session schedule: \--- The aim of this clinical trial is to evaluate the effectiveness of bioactive toothpastes, desensitizing agents, and Er-YAG laser treatments in reducing dentin hypersensitivity. This study also aims to assess the safety and comparative efficiency of these treatment methods. The main research questions are:

  • Do bioactive toothpastes, desensitizing agents, and laser treatments individually or in combination reduce dentin hypersensitivity?
  • Are there any adverse effects associated with these treatments? Participants will:
  • Be randomly assigned to one of four treatment groups, each using a specific toothpaste (Pro-Argin, Nano-Hydroxyapatite, NovaMin, or CPP-ACP), alongside desensitizing agents, laser treatments, or a placebo.
  • Receive two treatment sessions: the first at baseline and the second one week later.
  • Attend follow-up evaluations at the 2nd week, 1st month, and 3rd month to assess dentin hypersensitivity using the Visual Analog Scale (VAS) and dental unit air-water sprays. Researchers will compare the outcomes across groups using statistical analyses (Kolmogorov-Smirnov, Kruskal-Wallis, and Pearson/Spearman tests) to determine the most effective approach for managing dentin hypersensitivity.

Participants with dentin sensitivity in at least three teeth will be divided into four main groups. Subsequently, each of these main groups will be further divided into three subgroups. 1-) Colgate Sensitivity Pro-Solution (Pro-argin, USA) Subgroup 1a: Laser Subgroup 1b: 3M Clinpro White Varnish (TCP, USA) Subgroup 1c: Control (distilled water)

Interventions

In the laser treatment groups, the Fotona LightWalker® Erbium laser (2,940 nm) will be used, with each session lasting five minutes. During treatment, the energy density will be set to 20 J/cm², and the laser tip will be held perpendicular to the target area, applied in continuous and contact modes.

Masking Details
The participants will be aware of which toothpaste they are using; however, they will not know which of their teeth are receiving laser treatment or sensitivity-reducing agents. The evaluator, on the other hand, will be fully informed of all treatments administered. The treatment will create the impression that a protective cover is being placed on the other teeth after applying the laser treatment to one tooth, although the laser will only be directed at the specified tooth. Similarly, the sensitivity-reducing agent will be applied to one tooth, while distilled water will be applied to the other sensitive teeth. This approach ensures that the participant will remain unaware of which treatment has been applied to which tooth, allowing for an unbiased assessment of sensitivity.
