Summary
Certain orthodontic bonding adhesives, like Fuji Ortho SC, can release fluoride ions into tooth enamel, potentially reducing caries risk during orthodontic treatment with fixed appliances.
Area of Science:
- Dental Materials Science
- Cariology
- Orthodontics
Background:
- Dental caries is a significant concern during orthodontic treatment with fixed appliances.
- Orthodontic adhesives play a crucial role in bracket bonding and may influence enamel demineralization/remineralization.
- Evaluating the anticariogenic potential of orthodontic adhesives is essential for patient oral health.
Purpose of the Study:
- To assess the prophylactic potential of three orthodontic bonding adhesives: Fuji Ortho SC, Illuminate, and Resilience.
- To investigate fluoride ion release and incorporation into enamel from these adhesives.
Main Methods:
- Wistar Wag rats were used, with bands cemented to incisors using the tested adhesives.
- Enamel samples were analyzed at 6 and 12 weeks using scanning electron microscopy and energy dispersive spectrometry.
- Control groups received no adhesive treatment.
Main Results:
- No fluoride was detected in enamel at 6 weeks.
- Resilience composite showed no fluoride penetration at 12 weeks.
- Illuminate composite showed 2 µm fluoride penetration, while Fuji Ortho SC (resin-modified glass ionomer) demonstrated 4.8–5.7 µm penetration at 12 weeks.
Conclusions:
- Fluoride ions from certain orthodontic adhesives can integrate into the enamel surface layer.
- Fuji Ortho SC exhibits significant fluoride incorporation, suggesting its potential to mitigate caries during orthodontic treatment.
- Orthodontists can consider adhesives with fluoride-releasing properties to enhance caries prevention in patients undergoing fixed appliance therapy.
