Comparative evaluation of fluoro calcium phosphosilicate, calcium sodium phosphosilicate, and strontium chloride hexahydrate containing dentifrice for the treatment of dentin hypersensitivity: A randomized single-blind study

Aims and Objectives: This study aimed to evaluate and compare the clinical effectiveness of dentifrices containing fluoro calcium phosphosilicate, calcium sodium phosphosilicate, and strontium chloride hexahydrate for the treatment of dentin hypersensitivity (DH) when applied twice daily. Materials and Methods: Participants with a history of DH and with visual analog scale (VAS) score of ≥5 to a painful test stimuli response (dental explorer) in at least one tooth at the qualifying baseline visit were enrolled in this four-week randomized study. Participants (n = 93) were randomly allocated to one of the following groups: Group 1––fluoro calcium phosphosilicate (BioMin™), Group 2––calcium sodium phosphosilicate (NovaMin®), and Group 3––strontium chloride hexahydrate. Clinical effectiveness (VAS), perceived sensation score (verbal rating scale [VRS]), participants’ subjective assessment (four-item questionnaire) and oral health-related quality of life (Oral Health Impact Profile-14 [OHIP-14]) questionnaire) were assessed. Results: A significant (P < 0.0001) reduction in symptoms over a period of four weeks (from baseline) was noted in all groups; however, the intergroup difference was not statistically significant. At week 2, the percentage reductions in VAS (Group 1: 58.19%; Group 2: 49.18%; Group 3: 52.69%) and VRS (Group 1: 58.19%; Group 2: 47.16%; Group 3: 49.05%) scores were higher in Group 1 as compared with other groups. Subjective assessment results and oral health-related quality of life were comparable in all the three groups at the end of four weeks. Conclusion: Fluoro calcium phosphosilicate bioactive glass containing desensitizing dentifrice treatment may provide better treatment response for the treatment of DH because of its early onset of action in relieving hypersensitivity symptoms as compared with other dentifrices (CTRI/2018/04/013481).
