Exposed Hypersensitive Dentin Treated With Fluoride Iontophoresis With Remineralizing Agents

Clinical Evaluation of Exposed Hypersensitive Dentin Treated With Fluoride Iontophoresis Application in Comparison With Two Different Remineralizing Agents (a Randomized Clinical Trial)

The goal of this clinical trial is to learn if the application of fluoride works to treat patients suffering from dentin hypersensitivity. It will also learn about the safety of using fluoride iontophoresis with Acidulated phosphate fluoride gel.

The main questions it aims to answer are:

Does the remineralizing agent have the ability to decrease dentin sensitivity?

Researchers will compare Fluoride Iontophoresis with Acidulated Phosphate Fluoride gel , Casein phosphopeptides-Amorphus calcium phosphate (CPP-ACP), nano-hydroxyapptite (NHAP) and -active glass in decreasing dentin hypersensitivity

.

Participants will:

• Application of remineralizing agent every 3 months
• Visit the dental clinic once every 3 months for checkups and tests

Assess the efficacy of fluoride iontophoresis in remineralization in comparison with other ingredients.

Inclusion Criteria:

• Patients within 35-60 years of age.
• Each patient has 4 or more exposed roots of posterior teeth having sensitivity.
• Good oral hygiene.
• Patients who will agree to the consent and will commit to the follow-up period.
• Patients will follow instructions during study time.
• Teeth that were vital.

Exclusion Criteria:

• Patients with any systemic disease that may affect normal healing.
• Patient with bad oral hygiene, high caries index and high plaque index
• Patients participating in more than 1 dental study.
• Active carious lesions.
• Intrinsic and extrinsic stains.
• Any previous filling of selected teeth.
• Cracked and malformed teeth.
