    Abstract:
    AIM: The current study aimed to assess the efficiency of two desensitizing dentifrices on the management of dental hypersensitivity. MATERIALS AND METHODS: For the purpose of this investigation, 60 extracted human sound premolar teeth that were removed for orthodontic purposes were collected. On the buccal cervical areas, an inverted-cone bur was used to create cavities that were 2 mm deep and 3 mm wide. The blocks were submerged in 17% ethylenediaminetetraacetic acid (EDTA) for 40 minutes in order to ensure the complete dentin tubule opening. Following preparation, all samples were split into three groups, each containing 20 samples, Group A: Control, Group B: Dentifrice containing calcium sodium phosphosilicate, Group C: Dentifrice containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP). Scanning electron microscopy (SEM) was used to assess the occlusion of dentinal tubules. One-way analysis of variance (ANOVA) was used to assess the desensitization efficacy of dentifrices. At a p-value less than 0.05, statistical significance was determined. RESULT: Before application of different dentifrices, the maximum dentinal tubules opened in dentifrice containing CPP-ACP group (4.24 ± 0.10) followed by control group (4.18 ± 0.01) and dentifrice containing calcium sodium phosphosilicate (4.12 ± 0.06). And there was no significant difference between the different dentifrice groups (p > 0.001). After application of different dentifrices, the highest occlusion of dentinal tubules found in dentifrice containing CPP-ACP group (2.50 ± 0.05) followed by dentifrice containing calcium sodium phosphosilicate (2.84 ± 0.10) and control group (4.02 ± 0.07) and there was a highly significant difference between the different dentifrice groups (p < 0.001). CONCLUSION: On conclusion, dentifrice containing CPP-ACP exhibited the highest level of dentinal tubule occlusion in comparison to the control group and dentifrice containing calcium sodium phosphosilicate. CLINICAL SIGNIFICANCE: Dentinal hypersensitivity (DH) is a condition that is frequently experienced. With variable outcomes, a number of products are utilized in the management of DH. Need is felt in dentistry for a material that chemically reacts, physically occludes and adheres intimately to dentinal tubules to reduce the possibility of its recurrence.
