Summary

Dental sealant retention improved with sodium bicarbonate spray and fluoridated paste prophylaxis methods, regardless of etching time. These findings suggest optimal surface preparation enhances sealant durability for better caries prevention.

Area of Science:

  • Dental materials science
  • Preventive dentistry
  • Oral health research

Background:

  • Dental sealants are crucial for preventing pit and fissure caries.
  • Prophylaxis methods and etching times can influence sealant retention.
  • Optimizing surface preparation is key to sealant longevity.

Purpose of the Study:

  • To evaluate the retention of light-cured dental sealants.
  • To compare the effects of different prophylaxis methods on sealant retention.
  • To assess the impact of two etching times (15 and 30 seconds) on sealant retention.

Main Methods:

  • Eighty extracted third molars were used, sectioned, and divided into 8 groups.
  • Prophylaxis methods included pumice powder, fluoridated paste, sodium bicarbonate spray, and a control.

  • Tensile bond strengths were measured using a universal Instron testing machine after applying sealants with 15 or 30-second etching times.

    • Main Results:

    • No statistically significant difference in sealant retention was found between the 15 and 30-second etching times.
    • Statistically significant higher sealant retention was observed in groups using sodium bicarbonate spray and fluoridated paste compared to pumice powder and control.
    • ANOVA statistical analysis was employed to determine significance.

    Conclusions:

    • Prophylaxis method significantly impacts dental sealant retention.
    • Sodium bicarbonate spray and fluoridated paste are superior prophylaxis methods for enhancing sealant retention.
    • Etching time (15 vs. 30 seconds) did not significantly affect sealant retention in this study.
