Early Childhood Caries (ECC) is a global oral health problem, and Peru may be one of the countries with high prevalence of untreated ECC in South America. In this study, we constructed an epidemiologic profile of ECC in Peru through a comprehensive review of published data. The prevalence of ECC, risk factors for it, its impact on child development, and public oral health interventions on ECC have been included. The study revealed extremely high rates of ECC in Peru and significant oral-health disparities. Risk factors for ECC were poverty, high sugar consumption, and low oral health literacy. However, the number of studies is limited and their quality questionable. Oral health has not received high public-health priority in Peru. However, in recent years, new regulations and evidence-based documents (the first Clinical Practice Guideline for the Prevention, Diagnosis, and Management of Caries in Children; the Guideline for Children's healthy Growth and Development; the Law on Healthy Diet; and the Manual on Food Advertising) give hope for the future of infants' oral health in the nation.
Aim: To determine total fluoride (TF) concentration in Na2FPO3/Ca-based toothpastes, using fluoride ion selective electrode (F-ISE) by the direct technique, it is necessary to use acid (Ac+) to hydrolyze the FPO3 2- ion and to dissolve insoluble fluoride salts bound to the abrasive. For NaF/silicabased toothpastes, the use of acid is not necessary (Ac-) and a simplified protocol could be followed. Methods: Thus, we evaluated TF concentration in seven brands of NaF/silicabased toothpastes, following the validated conventional Cury’s protocol (Ac+) or a simplification of this protocol (Ac-). Fluoride was analyzed with ISE calibrated with fluoride standard solutions prepared in the same conditions as the samples (Ac+ or Ac-). Results: The mean (±SD; n=21) of TF concentrations (μg F/g) found by Ac+ (971.3±191.2) and Ac- (982.4±201.3) protocols were not statistically different (t test, p=0.22). The TF concentrations found agree with those declared by the manufacturers, except for one toothpaste imported from China. Conclusion: The findings suggest that the determination of fluoride in NaF/silica-based toothpastes can be accurately made using a simplified protocol of analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
