Fluoride and Sealants Win Fight Against Youth Dental Caries, says Review

Children and adolescents face significant oral health challenges, with dental caries being a prevalent concern. This condition, caused by sugar-metabolizing bacteria, can lead to cavities, pain, and decreased quality of life. 

Disparities in oral health services among school-aged children, linked to various factors such as location, race, and socioeconomic status, highlight the need for effective interventions to ensure universal access to dental care.

Research Aim and Scope

A recent systematic review, published in JAMA Network, aimed to equip the US Preventive Services Task Force (USPTF) with valuable insights into preventing oral health issues, especially dental caries, in young people aged five to 17. 

New Approach Offers Hope in Battle Against Dental Caries

The researchers conducted an extensive analysis, including three systematic reviews, 22 clinical trials, and an observational study, encompassing over 35,700 participants. Their focus on fluoride gels, supplements, varnish, and sealants provided critical data for dental practitioners, schools, and policymakers involved in the oral health of children and adolescents.

Oral Health Screening and Interventions

The study’s primary focus was to identify cohorts requiring oral health interventions and evaluate the effectiveness of these interventions. The researchers utilized key questions (KQs) to assess the accuracy of oral screening, risks associated with screening, and the positive and potential harms of interventions. 

Their systematic review included data from three medical databases, and outcomes were measured in terms of decayed, missing, or filled permanent teeth (DMFT index) or surfaces (DMFS).

Lack of Literature on Screening

The study revealed a significant gap in literature concerning oral health screening, with only one out of 76 publications addressing the topic. Trained nurses exhibited high sensitivity and specificity in visually identifying dental caries. Parents and guardians, using a checklist-type questionnaire, demonstrated moderate sensitivity and high specificity, suggesting that preliminary evaluations of dental health by non-dental professionals could be effective.

Effectiveness of Interventions

Meta-analysis of intervention data indicated that fluoride supplements, particularly in regions with nonfluorinated water, low socioeconomic status, or heavy caries burden, led to small decreases in DMFT/DMT. Dentist-administered fluoride gels, varnish, and sealants showed significantly improved caries outcomes, with sealants proving most effective. Limited data on xylitol’s effects prevented conclusive results. Unsupervised interventions and preventive measures displayed varying results, with some variables lacking sufficient data for conclusive analysis.

Balancing Benefits and Harms

The study noted low to moderate harm associated with interventions, primarily cosmetic in nature, such as blackening of teeth undergoing specific preventive treatments. However, no serious injuries were reported in any of the 76 studies evaluated.

The findings suggest that preliminary caries diagnoses in most settings may not necessitate a visit to a dental professional and can be effectively carried out by parents, guardians, nurses, and healthcare practitioners. While conclusive results on some hypotheses were limited by insufficient data, interventions involving fluoride supplements, gels, varnishes, and sealants were associated with improved oral health and reduced caries risk in children and adolescents. This research provides valuable insights for dental practitioners, schools, and policymakers striving to enhance oral health outcomes in the younger population.
