Clinical Evaluation of Giomer Based Varnish Versus CPP-ACP Varnish in the Management of Dentin Hypersensitivity: a Randomized Clinical Trial

Study Overview
=================
Brief Summary
-----------------
Dentin hypersensitivity is a drastic problem, which threaten many dental patients. According to the last published systematic review and meta analysis at 2019, the prevalence of dentin hypersensitivity is being 33.5% among the population. Moreover, it was determined that young adults with age range from 18 to 44 years exhibited high percentage (43.9%) of such problem

Detailed Description
-----------------
Several approaches to dentin hypersensitivity treatment were proposed to interfere, whether transiently or permanently, with the hydrodynamic theory. These approaches include root coverage and the use of lasers, ions, dentinal sealants, and occluding and nerve depolarization agents, chosen according to the primary cause. There are two major strategies in managing DH; the first is nerve desensitization, and the second is the physical occlusion of the patent tubule. The second approach can be carried out through a wide range of treatment modalities, including the use of proteins, salts or ions to plug the tubules. Many agents introduced are capable of sealing dentinal tubules, and can be used to reduce sensitivity. Of these agents are CPP-ACP varnish and the newly introduced giomer based varnish wilth S-PRG technology

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Giomer based Varnish<br> | Procedure: Giomer Varnish<br>* A light-cured Giomer varnish for prolonged hypersensitivity relief. Seals and protects exposed dentinal tubules to prevent pain. Ideal for patients experiencing loss of enamel, gingival recession<br>|
| Active Comparator: CPP-ACP based varnish<br> | Procedure: CPP-ACP varnish<br>* CPP binds to oral surfaces such as teeth, dentin, oral mucosa and biofilm. CPP-ACP Varnish delivers bioavailable calcium and phosphate ions to occlude dentinal tubules treating dentin hypersensitivity<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| evaporative test | using an air blast from a conventional dental unit air-water syringe for 5 seconds. | Immediately postoperative, after 1,3 and 6 months | 
| Thermal Test | using anaesthetic carpule kept in the refrigerator at 4oC for at least 24 hours till it became ice then it is removed from refrigerator immediately before testing . | Immediately postoperative, after 1,3 and 6 months | 
| Tactile test | using the tip of a sharp explorer (number 3) to gently scratch the exposed cervical surface in an apico-coronal direction with short strokes. | Immediately postoperative, after 1,3 and 6 months |
