Abstract

Purpose: To investigate the surface topography and nickel content of nickel-titanium (NiTi) archwires exposed to either routine oral hygiene or a prophylactic regimen with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) during orthodontic treatment.

Methods: This in vivo study involved 40 orthodontic patients with fixed appliances, who were randomly assigned to either a routine oral hygiene group or a CPP-ACP supplementary regimen group. Twenty new NiTi archwires served as controls. All archwires underwent scanning electron microscopy and energy-dispersive spectroscopy to evaluate their surface topography and elemental composition. The nickel content was quantified as a percentage of total weight and the Ni/Ti ratio, and statistical comparisons were made using pairwise tests.

Results: Wires exposed to fluoride toothpaste showed signs of pitting corrosion, deep grooves, and corrosion debris. In contrast, wires exposed to supplementary CPP-ACP exhibited smooth surface areas interspersed with microdefects and deposits. Statistically significant differences in nickel content were found between the new and retrieved archwires, as well as between wires exposed to routine oral hygiene and CPP-ACP (P < 0.001). The archwires exposed to CPP-ACP had the lowest nickel content (P < 0.001).

Conclusion: The use of CPP-ACP holds promise for application as a safe anticariogenic agent with possible protective properties during orthodontic treatment.

酪蛋白磷酸肽-无定形磷酸钙对固定矫治器正畸治疗期间镍钛弓丝表面形貌和成分的影响
目的:研究在正畸治疗期间暴露于常规口腔卫生或酪蛋白磷酸肽-无定形磷酸钙(CPP-ACP)预防方案的镍钛(NiTi)弓丝的表面形貌和镍含量:这项体内研究涉及 40 名使用固定矫治器的正畸患者,他们被随机分配到常规口腔卫生组或 CPP-ACP 补充疗法组。20 个新的镍钛弓丝作为对照组。所有弓丝都进行了扫描电子显微镜和能量色散光谱分析,以评估其表面形貌和元素组成。对镍含量占总重量的百分比和镍/钛比进行量化,并通过配对检验进行统计比较:结果:接触含氟牙膏的金属丝出现点状腐蚀、深沟和腐蚀碎屑。与此相反,暴露于补充性 CPP-ACP 的金属丝表面光滑,其间夹杂着微缺陷和沉积物。新的弓丝和回收的弓丝之间,以及暴露于常规口腔卫生和 CPP-ACP 的弓丝之间,镍含量存在明显的统计学差异(P <0.001)。使用 CPP-ACP 的弓丝镍含量最低(P < 0.001):CPP-ACP作为一种安全的抗龋齿剂,在正畸治疗期间可能具有保护作用。
