Summary
This study determined optimal timing for school-based dental sealant programs by analyzing molar eruption in Ohio schoolchildren. Findings reveal age-specific eruption patterns crucial for effective caries prevention.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Epidemiology
Background:
- Dental caries is a common childhood disease, with pits and fissures being highly susceptible.
- Dental sealants are effective in preventing caries on these vulnerable tooth surfaces.
Purpose of the Study:
- To develop a timing strategy for school-based occlusal sealant programs.
- To assess the eruption status of first and second permanent molars in schoolchildren.
Main Methods:
- An eruption score was developed to evaluate molar eruption status.
- Data from 4,879 Ohio schoolchildren (grades 1-3, 6-8, 11) were analyzed.
- Analyses considered grade, sex, race, locale, fluoridation, and socioeconomic status.
Main Results:
- 57% of first graders had fully erupted first permanent molars suitable for sealants.
- 23.6% of sixth graders had sufficiently erupted second molars.
- Females exhibited earlier molar eruption than males; Black children showed earlier second molar eruption than white children.
Conclusions:
- Provides state-specific data to guide the initiation of school-based occlusal sealant programs.
- Highlights the importance of considering eruption timing for maximizing sealant effectiveness.
- Informs dental public health decision-making for pediatric caries prevention strategies.
