Abstract

(1) Background: This study aimed to establish the effect of calcium lactate enamel pretreatment related to different fluoride types and concentrations on the enamel uptake of alkali-soluble fluorides. (2) Materials: In a blind and randomized in vitro study, a total of 60 teeth are used. The first 30 teeth were cut and randomly allocated into one of the following treatments: (A) calcium lactate pretreatment followed by three different fluoride solutions; (B) the "Fluoride only" group, with slabs treated with three different fluoride solutions; (C) the "Calcium only" group, with slabs treated with calcium lactate solution; (D) slabs treated with deionized water (negative control group). The next 30 teeth underwent all the above described group procedures but were treated with lower fluoride concentrations. Fluoride was extracted from enamel using 1 M KOH solution and analyzed using a fluoride ion-specific electrode. (3) Results: The findings revealed that slabs treated with NaF following calcium lactate pretreatment exhibited significantly greater enamel uptake of alkali-soluble fluoride compared to other substrates. This significant effect was not observed at lower fluoride concentrations. (4) Conclusion: The study demonstrates that pretreatment with calcium lactate followed by treatment with NaF at 226 ppm F significantly enhances the uptake of alkali-soluble fluoride in enamel compared to other fluoride types.

乳酸钙预处理对牙釉质摄氟量的影响：不同氟化物类型和浓度的体外比较研究

(1) 背景：本研究旨在确定不同氟化物类型和浓度的乳酸钙釉质预处理对釉质吸收碱溶性氟化物的影响。(2）材料：在一项盲法随机体外研究中，共使用了 60 颗牙齿。切取前 30 颗牙齿，随机分配到以下处理中：(A）乳酸钙预处理，然后用三种不同的氟化物溶液处理；（B）"仅氟化物 "组，用三种不同的氟化物溶液处理牙板；（C）"仅钙 "组，用乳酸钙溶液处理牙板；（D）用去离子水处理牙板（阴性对照组）。接下来的 30 颗牙齿进行了上述所有分组程序，但使用的氟浓度较低。使用 1 M KOH 溶液从牙釉质中提取氟，并使用氟离子特异性电极进行分析。(3) 结果：研究结果表明，与其他基质相比，经乳酸钙预处理后再用 NaF 处理的牙板的釉质对碱溶性氟化物的吸收率明显更高。在氟浓度较低的情况下，没有观察到这种明显的效果。(4) 结论：该研究表明，与其他氟化物类型相比，用乳酸钙预处理后再用百万分之 226 的 NaF 处理，能显著提高釉质对碱溶性氟化物的吸收。

期刊介绍： Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
