摘要

目的：评价成膜聚合物和钙改性软饮对牛牙釉质和牙本质的侵蚀潜力。方法：用线性聚磷酸钠（LPP-10g/L）和三偏磷酸钠（TMP-10g/L）单独或与五水乳酸钙（CLP-4.35 g/L）联合对雪碧零糖进行改性。牙釉质和牙本质标本随机分为6组（n=10/基质）：1。C-（阴性控制-不修改）；2. 垂直距离;3. TMP;4. 垂直距离+ CLP;5. TMP + CLP;6. C+（阳性对照- clp）。标本经历了侵蚀-再矿化循环。用光学轮廓仪测量表面损耗（SL，单位μm）。分析了饮料的颜色和粘度。对数据进行统计学分析（α=0.05）。结果：与C-相比，LPP对牙本质和牙釉质的侵蚀作用明显降低（p0.05）。结论：所有含乳酸钙（CLP）的溶液均能有效降低原软饮料的侵蚀电位。CLP与LPP或TMP联合使用可显著增强保护作用，尤其是对牙本质的保护作用。值得注意的是，LPP单独有效地减少了牙釉质和牙本质的侵蚀。临床意义：减少软饮料的侵蚀潜力可能有利于非合作的高牙齿侵蚀磨损风险的个人。

Reduction of the erosive potential of a soft drink with polymers and calcium

Objectives

To evaluate the erosive potential of a soft drink modified with film-forming polymers and calcium on bovine enamel and dentin.

Methods

Sprite Zero Sugar was modified with linear sodium polyphosphate (LPP–10 g/L) and sodium trimetaphosphate (TMP-10 g/L), individually or combined with calcium lactate pentahydrate (CLP–4.35 g/L). Enamel and dentin specimens were randomly assigned into six groups (n = 10/substrate): 1. C− (negative control–no modification); 2. LPP; 3. TMP; 4. LPP+CLP; 5. TMP+CLP; 6. C+ (positive control–CLP). The specimens underwent an erosion-remineralization cycling. Surface loss (SL, in μm) was measured with an optical profilometer. Color and viscosity of the drinks were analyzed. Data were statistically analyzed (α=0.05).

Results

For enamel and dentin, LPP significantly reduced the erosive effect of the drink compared to C- (p < 0.001 for both), with reductions of approximately 53 % and 41 %, respectively. TMP showed no significant difference from C− for both substrates. C+ reduced SL by 87 % in enamel and 38 % in dentin when compared to C− (p < 0.001). When CLP was combined with the polymers, in enamel, a 97 % reduction in SL for LPP+CLP and TMP+CLP was observed. In dentin, reductions of 56 % and 48 % were observed for LPP+CLP and TMP+CLP. No significant differences were observed between the groups and the C- regarding color and viscosity (p > 0.05).

Conclusions

All solutions containing calcium lactate (CLP) were effective in reducing the erosive potential of the original soft drink. The combinations of CLP with LPP or TMP significantly enhanced protection, especially for dentin. Notably, LPP alone was effective in minimizing erosion of both enamel and dentin.

Clinical relevance

Reducing the erosion potential of soft drinks may benefit non-collaborative individuals with high risk for erosive tooth wear.

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
