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

Not Applicable

Recruiting

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

Recruitment & Eligibility

Inclusion Criteria

Participants of both genders aged 18 to 40 years with good oral hygiene, suffering from pain due to dentin hypersensitivity in at least one tooth

Exclusion Criteria

Taking desensitizing treatment in the last 6 months. (It affects the outcome)
