Area of Science:

  • Dental materials science
  • Pediatric dentistry
  • Clinical research

Background:

  • Pit-and-fissure sealants are crucial for preventing dental caries in children.
  • Effective isolation is essential for optimal sealant retention and longevity.
  • Various isolation techniques exist, but their comparative efficacy for sealants needs evaluation.

Purpose of the Study:

  • To compare the retention rates of visible-light-cured pit-and-fissure sealants.
  • To evaluate the impact of two isolation methods (cotton rolls vs. VacEjector) on sealant retention.
  • To determine if isolation technique influences sealant longevity in pediatric patients.

Main Methods:

  • A prospective clinical study involving 523 school children.
  • Application of a white, visible-light-cured pit-and-fissure sealant.

  • Teeth were isolated using either cotton rolls or a VacEjector system.
  • Sealant retention was assessed after a minimum six-month follow-up period.

    • Main Results:

    • No statistically significant difference in sealant retention was observed between the cotton roll and VacEjector isolation groups.
    • Both isolation methods facilitated successful sealant application and maintenance.
    • The overall retention rates were comparable across both tested isolation techniques.

    Conclusions:

    • Cotton rolls and the VacEjector system are equally effective for isolating teeth during pit-and-fissure sealant application in children.
    • Clinicians can select either isolation method without compromising sealant retention.
    • This finding supports the use of readily available or advanced isolation techniques for effective caries prevention in pediatric dentistry.
