Objective: to evaluate the efficacy of non-invasive procedures through biomimetic mineralization of a fluoride gel, bioactive glass materials with and without fluoride and self-organizing biomimetic peptides in the treatment of dentinal hypersensitivity due to early non-carious cervical lesions.
Materials and methods: Twenty-eight patients with self-reported history of dentin hypersensitivity were evaluated sequentially for evidence of erosion, abrasion or gingival recession at facial cervical region. Patients were randomly distributed into four treatment groups of seven patients each according to the type of the treatment (group I: Elmex Gele'e, group II: BioMin™ F, group III: BioMin™ C group IV: CurodontTM D'senz). The teeth were subjected to five follow up periods (baseline, after 3,6,9 and 12 weeks) and assessed in response to evaporative air-blast stimulus utilizing Schiff Sensitivity and Visual Analogue Scales. Electrical test was performed utilizing electrical pulp tester. The extent of tubule occlusion was examined under scanning electron microscope using negative replica of randomly selected patients.
Results: All the tested groups showed different degrees of relieving dentinal hypersensitivity symptoms. The difference between the studied groups was statistically significant. Under SEM, group II, III and IV showed complete tubule occlusion. However, group I showed partial tubule occlusion.
Conclusions: Elmex® gelée, BioMin™ F, BioMin™ C and Curodont™ D'senz were effective to manage dentin hypersensitivity related to early non-carious cervical lesions based on the biomimetic mineralization concept that has focused on permanent management of dentin hypersensitivity.
