Summary
Fissure sealants show better retention in deciduous molars compared to permanent molars over 18 months. Sealant loss is most significant on the disto-occlusal pit of upper first permanent molars.
Area of Science:
- Pediatric Dentistry
- Dental Materials Science
Context:
- Fissure sealants are crucial for preventing dental caries in molars.
- Understanding sealant retention is key to optimizing caries prevention strategies.
Purpose:
- To evaluate and compare the retention rates of fissure sealants in deciduous and permanent molars over an 18-month period.
Summary:
- A comparative study assessed fissure sealant retention in deciduous molars and first permanent molars at 6-month intervals.
- Results after 18 months indicated superior sealant retention in deciduous molars, followed by upper and lower first permanent molars.
- The disto-occlusal pit of upper first permanent molars exhibited the greatest sealant loss.
Impact:
- Findings suggest potential differences in sealant longevity between primary and permanent dentition.
- Highlights specific areas within permanent molars prone to sealant failure, informing clinical application and material development.
