Evaluation of ozonated olive oil with or without adjunctive application of calcium sodium phosphosilicate on post-surgical root dentin hypersensitivity: a randomized, double-blinded, controlled, clinical trial.

AIM

This study was conducted to evaluate the efficacy of ozonated olive oil with or without adjunctive application of mineral wash containing calcium sodium phosphosilicate on the reversal of post-surgical root dentin hypersensitivity.

METHODS

A double-blinded, randomized controlled clinical trial was conducted on 51 participants with root dentin hypersensitivity (RDH). Participants were randomLy assigned to 4 groups: Group A, ozonated olive oil (OZO): Group B, ozonated olive oil and mineral wash: Group C, placebo olive oil (PPO) and mineral wash: Group D, placebo olive oil only. Active treatment was carried out in-clinic and followed by at-home care with a remineralising paste. The response to various pain stimuli was periodically assessed with a visual analogue scale. Additionally, scanning electron microscopic study assessed the dentinal tubule occlusion and change in tubular surface area after treatment.

RESULTS

The group B participants showed a significant decrease in tooth level and global sensitivity over the period (P<0.001). Moreover, the intergroup comparison also revealed a significant result (P<0.001). Similarly, participants of group C also showed a significant reduction in sensitivity over the period (P<0.001). Whereas, no significant (P>0.05) difference was detected between group A and group D for tooth level and global sensitivity analysis. The SEM study result showed a significantly (P<0.001) enhanced tubule occlusion and decreased tubular surface area in group B specimens compared to other group specimens.

CONCLUSION

OZO, as a mono-therapy is not efficient in reducing post-surgical RDH. However, the adjunctive application of mineral wash containing calcium sodium phosphosilicate has positive impact on the reversal of post-surgical root dentin hypersensitivity.
