Dentin hypersensitivity (DH) is a sharp toothache that influences a patients' oral health-related quality of life. Oral dentifrices have been marketed for pain relief within a minute for DH. The permanent management of DH is being investigated with the remineralisation potential of bioactive agents in dentinal tubules. This study investigated the relief from pain in DH in one minute after applying over the counter (OTC) dentifrices with Pro-Argin™ and strontium acetate and directly compared them with fluoro-calcium phospho-silicate (FCPS)-based dentifrices for immediate and sustained inhibition of painful stimulus provoking DH.
A randomised, controlled, triple-blinded clinical trial was conducted with 140 participants clinically diagnosed with DH and equally randomized into four groups with parallel treatment assignment of FCPS, Pro-Argin™, 8% strontium acetate, and sodium fluoride-based OTC dentifrices, and tested for DH with air blast, mechanical, and water jet stimuli on SCHIFF cold air sensitivity scale (SCASS) and visual analogue scale (VAS) at interim efficacy intervals of one minute, three days, two, four, and six weeks, subsequently.
A total of 128 participants completed the trial. All the treatment groups showed statistically significant improvement in DH with p < 0.001 relative to baseline at all time points. Pro-Argin™ showed a greater reduction in DH with mean scores of (1.34 ± 0.68) (4.20 ± 1.70) (3.05 ± 2.17) followed by strontium acetate (1.57 ± 0.81) (4.65 ± 1.87) (3.75 ± 1.97) on SCASS and VAS for mechanical and water jet stimuli, one minute after application. There was no statistically significant treatment difference between the two (p = 0.499). FCPS showed the highest reduction in DH on SCASS and VAS for waterjet stimuli with mean scores of (0.97 ± 0.68) (1.80 ± 1.73) and Pro-Argin™ on VAS for mechanical stimuli with mean scores of (2.15 ± 1.92) in six weeks.
OTC dentifrices with Pro-argin™ and strontium acetate are effective for immediate pain relief from DH, and FCPS could be the best possible treatment option for long term management of DH.

牙本质过敏症(DH)是一种剧烈的牙痛,会影响患者的口腔健康相关生活质量。市售的口腔牙膏声称可在一分钟内缓解疼痛。目前正在研究具有生物活性物质在牙本质小管中再矿化潜力的方法来对 DH 进行永久性治疗。本研究旨在一分钟内应用含有 Pro-Argin™和乙酸锶的非处方牙膏后,观察其对 DH 疼痛缓解的效果,并与基于氟钙磷硅酸钠(FCPS)的牙膏进行直接比较,以观察其对引起 DH 的疼痛刺激的即刻和持续抑制作用。
采用随机、对照、三盲临床试验,共纳入 140 例临床诊断为 DH 的患者,按平行分组方式随机分为 FCPS、Pro-Argin™、8%乙酸锶和基于氟化物的非处方牙膏组,并用冷气流敏感量表(SCASS)和视觉模拟量表(VAS)分别在一分钟、三天、两周、四周和六周的中间疗效间隔期评估空气喷流、机械刺激和水射流刺激下的 DH 情况。
共有 128 名患者完成了试验。所有治疗组在所有时间点均显示 DH 有统计学显著改善(p<0.001)。Pro-Argin™在一分钟后机械刺激和水射流刺激时的 DH 缓解程度最大,平均得分分别为(1.34±0.68)、(4.20±1.70)、(3.05±2.17),其次是乙酸锶(1.57±0.81)、(4.65±1.87)、(3.75±1.97)。SCASS 和 VAS 上均无统计学显著差异(p=0.499)。FCPS 在水射流刺激的 SCASS 和 VAS 上对 DH 的缓解程度最高,平均得分分别为(0.97±0.68)、(1.80±1.73),Pro-Argin™在 VAS 上对机械刺激的缓解程度最大,平均得分分别为(2.15±1.92)。
含有 Pro-argin™和乙酸锶的非处方牙膏可即刻缓解 DH 疼痛,FCPS 可能是 DH 长期管理的最佳治疗选择。
