Abstract

Introduction: Dentifrice tablets are increasingly presented as a more sustainable alternative to regular toothpastes, yet evidence regarding their efficacy is still limited. This study aimed to evaluate the quality of dentifrice tablets available on the Dutch market with respect to their total fluoride content and their potentially available fluoride.

Methods: Twenty types of dentifrice tablets were analyzed using two different techniques: an ion-selective electrode and gas-liquid chromatography. Prior to analysis, two criteria were defined: (1) total content of fluoride should be >80% of the content that the manufacturer claimed and (2) the potentially available fluoride content should be ≥80% of the measured total fluoride content.

Results: Nine of the twenty tablets met both criteria. Moreover, most tablets had a lower weight than the amount of toothpaste recommended by the Dutch Ivory Cross. This variation in quality, combined with the relatively lower mass of dentifrice tablets raises concerns regarding the reliability of dentifrice tablets for caries prevention.

Conclusion: Although these tablets were purchased on the Dutch market, the results of this study suggest that dentifrice tablets in general may lack sufficient quality control.

荷兰市场上牙膏片的氟化物含量及其潜在可用性——实验室评估。

牙膏片越来越多地被认为是普通牙膏的一种更可持续的替代品，但有关其功效的证据仍然有限。本研究旨在评估荷兰市场上出售的牙膏片在总氟化物含量和潜在可用氟化物方面的质量。采用离子选择电极和气液色谱法对20种牙膏片进行了分析。在分析之前，定义了两个标准；1)总氟化物含量应为制造商声称的含量的80 ~ 80；2)潜在可用氟化物含量应为测量的总氟化物含量的≥80。20片中有9片同时符合这两个标准。此外，大多数药片的重量低于荷兰象牙十字会推荐的牙膏重量。这种质量上的差异，再加上牙膏片的质量相对较低，引起了人们对牙膏片预防龋齿的可靠性的关注。虽然这些药片是在荷兰市场上购买的，但本研究的结果表明，牙膏片总体上可能缺乏足够的质量控制。

期刊介绍： ''Caries Research'' publishes epidemiological, clinical and laboratory studies in dental caries, erosion and related dental diseases. Some studies build on the considerable advances already made in caries prevention, e.g. through fluoride application. Some aim to improve understanding of the increasingly important problem of dental erosion and the associated tooth wear process. Others monitor the changing pattern of caries in different populations, explore improved methods of diagnosis or evaluate methods of prevention or treatment. The broad coverage of current research has given the journal an international reputation as an indispensable source for both basic scientists and clinicians engaged in understanding, investigating and preventing dental disease.
