In the era of rapid digitalization, modern dentistry is developing as one of the most dynamic fields of medicine, integrating clinical and technological innovations.
In this context, a key factor of progress becomes not only the development of new formulations of preventive agents, but also their clinical validation and diffusion in the population, which is important for making evidence-based decisions in state and municipal programs for the prevention of childhood caries. This review analyzes a randomized controlled trial from Hong Kong evaluating fluoride varnish with functionalized tricalcium phosphate (fTCP), and interprets the results from a practical perspective for pediatric clinicians and public health.
Functionalized tricalcium phosphate (fTCP) was developed to prevent premature reaction of calcium and phosphate with fluoride, ensuring stable delivery of calcium and phosphate ions to the tooth surface and promoting reproducible remineralization of enamel. From a clinical perspective fTCP is considered a component aimed at enhancing the deposition of calcium and phosphate phases on microporosities of enamel and at increasing the predictability of remineralization after application of fluoride varnish.
The mechanism of action consists of modulating local kinetics of ionic exchange and creating a favorable microenvironmental charge on the tooth surface — this may increase the potential for formation of apatite-like phases and improve restoration of demineralized areas provided adequate contact and repeated applications.
The study was randomized, double-blind, included three-year-old children with active untreated carious lesions and was conducted over two years with periodic examinations and interim outcome assessment.
Participants were randomized to receive either standard 5% sodium fluoride or fluoride varnish with included fTCP, applications were performed every six months. Before application of the fluoride varnish all active carious lesions were treated with silver nitrate as part of a two-step protocol aimed at stimulating caries arrest and infection control. Outcomes were assessed at the child level and at individual tooth surfaces, including appearance of new cavitations and change in the number of affected surfaces.
At the child level no significant differences in aggregate clinical outcomes between groups were found — rates of new cavities and increases in the number of affected teeth were comparable. Surface-level analysis demonstrated a slight reduction in the number of affected intact surfaces in the fTCP group, most pronounced on lower posterior teeth, however this difference was not statistically significant. More than four out of five children — over 80 percent of participants — experienced at least one new cavitated lesion during follow-up, underscoring the high residual risk in the baseline population.
The study authors hypothesized that widespread use of systemic and household sources of fluoride — fluoridated water, fluoride-containing toothpaste — could have minimized the additional effect of fluoride varnish with fTCP, reducing the margin of clinical advantage under comparable protocols. Ultimately the researchers concluded that both formulations exert equivalent preventive effectiveness and may be used in pediatric prevention programs provided protocols are standardized and local fluoridation factors are taken into account.
The context of the Hong Kong population — high prevalence of use of fluoride-containing preventive measures, population density and organized health programs — affects the translational significance of the results for other regions. In populations with high levels of systemic or household fluoridation the additional effect of local compositional modifications may be erased; in regions without fluoridation the effect of fluoride varnish with fTCP may be more pronounced.
From a practical standpoint it is important to consider the epidemiological profile — predisposing factors, accessibility of dental services, standard protocols for the use of silver and fluoride varnish, as well as behavioral and socio-economic determinants. For planning prevention programs it is necessary to synchronize educational initiatives, clinical protocols and monitoring of quality of service delivery.
For pediatric clinicians and prevention program coordinators it is advisable to use a risk-oriented approach: assessment of individual and caries-exposure risk, prioritizing resources for high-risk groups, combining local methods (fluoride varnishes, applications of silver nitrate/silver diamine fluoride, remineralizing applications) with behavioral interventions and oral hygiene programs.
The practical conclusion is as follows — fluoride varnish with fTCP may be considered as a component of a multilayered strategy for primary and secondary prevention, however its universal advantage over standard 5% sodium fluoride was not demonstrated in settings where fluoridation is already widespread. In routine clinical practice it makes sense to take into account cost, availability, tolerability and to combine the choice of formulation with application frequency, dietary control and educational activities.
Expert comment: for patients with pronounced caries risk or in the presence of active cavitations combined protocols — treatment with a silver solution followed by remineralization and frequent applications of remineralizing agents — remain justified. Standardized measures are also important for assessing intervention effectiveness, including clinical photography, radiography when necessary and objective scales of progression/arrest of caries.
Studies with long follow-up periods and in populations with different levels of fluoridation are needed to refine the groups of patients most likely to benefit from the addition of fTCP. Effectiveness studies in real-world care settings, economic evaluation, analysis of impact on the microflora and use of molecular markers of remineralization will contribute to full profiling of clinical benefit. Also important are studies to optimize concentration, frequency of applications and combined protocols with anti-infective agents to halt progression of cavitations.
Fluoride varnish with functionalized tricalcium phosphate demonstrates a biochemically justified potential to enhance remineralization, however in settings of high background fluoride prevention the clinical advantage over standard 5% sodium fluoride proved insignificant. For practical application it is important to integrate these data into risk-oriented prevention programs, consider the epidemiological context and combine local technologies with public health measures and educational strategies.
