[PMID: 37025919 PMCID: PMC10070521 DOI: 10.1016/j.heliyon.2023.e14634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 03/02/2023] [Accepted: 03/13/2023] [Indexed: 03/18/2023] Open
Abstract
Objective The purpose of this randomized controlled trial was to compare the efficacy of a toothpaste containing paeonol, potassium nitrate, and strontium chloride with control toothpaste on dentine hypersensitivity (DH). Methods DH patients who had at least two sensitive teeth and did not use desensitization toothpaste in the past 3 months were randomly allocated to either test or control group. The toothpaste containing paeonol, potassium nitrate, and strontium chloride was used in the test group, while the placebo toothpaste used in control group. The outcome measures included Yeaple probe score and Schiff Index score at 4 and 8 weeks. The patients, personnel and assessors were blinded to the allocation. The differences in Yeaple probe score and Schiff Index score between groups were analyzed with ANOVA. Results 91 eligible subjects were randomized. 88 of them completed 8-week follow-up and were analyzed (45 in the test group and 43 in the control group). In both groups, the Yeaple probe score showed an upward trend, while the Schiff sensitivity score showed a downward trend. At week 8, the Yeaple probe score had increased by 30.22 g in the test group, and the Schiff Index score had decreased by 0.89. Compared with the control group, the Yeaple probe score in the test group increased by 286.85% from baseline, and the Schiff Index score decreased by 42.96%, showing a statistically significant difference. Five cases of adverse events were observed. Conclusion The toothpaste containing paeonol, potassium nitrate, and strontium chloride was effective against DH. Clinical significance This combination of paeonol, potassium nitrate and strontium chloride could be a novel functional ingredient choice for anti-hypersensitivity products in future. Registration The trial was registered in the Chinese Clinical Trial Registry (ChiCTR2000041417).

Abstract
Background The remineralization approach mechanically occludes the exposed dentinal tubules mechanically, reduces the permeability of dentinal tubules and eliminates the symptoms of dentin hypersensitivity. The aim of the present study was to investigate the remineralization of demineralized dentin slices using CPP–ACP combined with TPP, and the research hypothesis was that CPP–ACP combined with TPP could result in extrafibrillar and intrafibrillar remineralization of dentin. Methods Demineralized dentin slices were prepared and randomly divided into the following groups: A (the CPP–ACP group), B (the CPP–ACP + TPP combination group), C (the artificial saliva group), D (the negative control group), and E (the positive control group). Dentin slice samples from groups A, B and C were remineralized and the remineralization effect was evaluated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), attenuated total reflection–Fourier transform infrared spectroscopy (ATR–FTIR) and X-ray diffraction (XRD). Results Treatment with CPP–ACP combined with TPP occluded the dentinal tubules and resulted in remineralization of collagen fibrils. The hydroxyapatite crystals formed via remineralization were found to closely resemble the natural dentin components. Conclusion CPP–ACP combined with TPP has a good remineralization effect on demineralized dentin slices.
