Clinical Effectiveness of Episodic Use of Bioactive Silica Based Versus in Management of Dentin Hypersensitivity (A 6m Randomized Clinical Trial)

Clinical Effectiveness of Episodic Use of Bioactive Silica Based Versus Continuous Use of Fluoride Desensitizing Toothpastes in Management of Dentin Hypersensitivity (A 6m Randomized Clinical Trial)

The aim of the study to compare the clinical effectiveness of Episodic use of Bioactive Silica Based versus continuous use of fluoride based desensitizing toothpastes in management of dentin hypersensitivity (DH) of adult patients over 6m follow up and evaluating patient satisfaction regarding the treatment provided. Episodic use will be tested as it reflects the effectiveness in a clinical scenario regarding patient compliance and adherence to the treatment where some of the Egyptian patients stop the treatment once improvement occurs due to financial constraints

Inclusion Criteria:

Patients with DH, VAS ≥ 3 and Schiff sensitivity score needed to be ≥2, indicating that application of a jet of air makes the patient respond and move or requests discontinuation of the stimuli application.

• Teeth with DH related to Non- carious Cervical lesions (abrasion, abfracture, erosion).

• Teeth with gingival recession and exposed root dentin.

Exclusion Criteria:

• Patients with known allergies or adverse reactions to any ingredient of the tested materials.

Systematic disease and/ or physical disabilities that may affect participation. • Patients who did any periodontal surgeries within the previous 3 months.

• Patients with orthodontic appliances, or restorative work that might interfere with evaluation.

• Patient who frequently use analgesics or any drugs that could affect the pain level.

• Home or in-office bleaching and/ or in office fluoride application for 6 months before beginning of treatment.

• Pregnant females with frequent vomiting attacks.

• Smokers.

• Systemic conditions that cause or predispose patients to develop dentin hypersensitivity (for example, gastroesophageal reflux disease, GERD).

• Excessive dietary or environmental exposure to acids.
