    School-based dental sealants significantly reduced tooth decay in New Mexico children. Sealants protected first permanent molars, with decay rates dropping from 26.85% to 5.6% in treated students.

    Area of Science:

    • Public Health
    • Pediatric Dentistry
    • Preventive Dentistry

    Background:

    • A school-based dental sealant program was initiated in New Mexico in 1979.
    • The program targeted children in multiple grades, offering sealants to prevent tooth decay.

    Purpose of the Study:

    • To evaluate the long-term effectiveness of dental sealants applied in elementary school.
    • To assess the impact of early sealant application on the condition of permanent molars.

    Main Methods:

    • A cohort of sixth-grade students who received sealants in earlier grades (1-3) was tracked.
    • Occlusal surfaces of first permanent molars were examined for decay, missing teeth, or fillings.
    • Retention rates of sealants were recorded at one, five, and six years post-application.

    Main Results:

    • Sixth graders with prior sealants had significantly lower rates of decayed, missing, or filled occlusal surfaces (5.6%) compared to untreated classmates (26.85%).
    • Complete sealant retention rates were high: 93.47% after one year, 78.53% after five years, and 67.36% after six years.
    • Partial sealant retention rates were 3.04% after one year, 10.63% after five years, and 10.46% after six years.

    Conclusions:

    • School-based dental sealants are highly effective in preventing decay in permanent molars.
    • Sealants provide durable protection for several years, demonstrating a significant public health benefit.
    • Early intervention with dental sealants is a cost-effective strategy for improving child dental health.
