Fluoride-releasing dental restorations, such as glass ionomers, significantly reduce cavities on adjacent tooth surfaces. This finding highlights the protective benefits of specific restorative materials in preventing secondary caries.
Area of Science:
- Dental Materials Science
- Cariology
- Restorative Dentistry
Background:
- Class II restorations alter the local oral environment, impacting adjacent teeth.
- Leachable components from dental restorations can influence caries development on neighboring surfaces.
Purpose of the Study:
- To evaluate the effect of different Class II restorative materials on caries development in adjacent proximal tooth surfaces.
- To assess the caries status of unrestored surfaces adjacent to various filling materials over time.
Main Methods:
- Review of practice-based clinical studies involving 1341 unrestored proximal surfaces adjacent to Class II restorations.
- Assessment of caries status (sound, active, arrested) over up to eight years.
- Inclusion of restorations from nine clinicians with standardized training.
Main Results:
- Surfaces adjacent to fluoride-releasing materials (glass ionomers, resin-modified glass ionomers, compomers) showed reduced caries development and progression.
- A lower rate of caries was observed compared to surfaces adjacent to amalgam restorations.
Conclusions:
- Fluoride-releasing restorative materials effectively reduce the incidence and progression of primary caries on adjacent proximal surfaces.
- The choice of restorative material plays a critical role in managing secondary caries risk.
