|October 1, 1976
Summary
A polymeric adhesive coating significantly reduced tooth decay under loose orthodontic bands. This protective effect surpassed that of acidulated phosphate fluoride and stannous fluoride, offering a promising solution for preventing decalcification.
Area of Science:
- Dental Materials Science
- Cariology
- Orthodontic Research
Background:
- Loose orthodontic bands can lead to tooth decalcification.
- Preventing enamel demineralization beneath orthodontic appliances is crucial for oral health.
Purpose of the Study:
- To evaluate the efficacy of a polymeric adhesive coating in preventing decalcification under simulated loose orthodontic bands.
- To compare the protective effects of polymeric adhesive coating, acidulated phosphate fluoride, and stannous fluoride against decalcification.
Main Methods:
- Extracted premolar teeth were divided into four groups: polymeric adhesive coating, acidulated phosphate fluoride, stannous fluoride, and a control.
- Loosely fitted orthodontic bands were cemented, simulating in vivo conditions.
- Teeth were immersed in a decalcifying gelatin for 11 weeks to assess demineralization.
Main Results:
- All tested treatments (polymeric adhesive coating, acidulated phosphate fluoride, stannous fluoride) significantly reduced decalcification compared to the control group.
- The polymeric adhesive coating demonstrated superior protection against decalcification under loose orthodontic bands compared to both fluoride treatments.
Conclusions:
- Polymeric adhesive coatings offer a highly effective method for preventing enamel decalcification beneath loose orthodontic bands.
- Topical fluoride applications also provide protection, but the polymeric adhesive coating shows greater efficacy in this specific application.
