Summary
Dental adhesion materials are advancing, with polymer-based systems and phosphoric acid etching for enamel showing promise. However, consistent success in clinical applications like fissure sealants requires specialized training and further research into dentine adhesion.
Area of Science:
- Dental Materials Science
- Adhesion Science
- Polymer Chemistry
Background:
- Adhesion is crucial in various dental applications, driving the need for effective adhesive restorative materials.
- Current advancements focus on polymer-based materials for new dental indications.
- Understanding the physico-chemical principles of adhesion is fundamental to developing new dental materials.
Purpose of the Study:
- To review materials and techniques for achieving dental adhesion, particularly to enamel.
- To assess the efficacy of current adhesive technologies, including microretention via phosphoric acid etching.
- To evaluate the potential of novel polymer systems for chemical adhesion to dentine.
Main Methods:
- Review of physico-chemical principles of adhesion.
- Survey of clinical investigations on fissure sealants and adhesive restorations.
- Analysis of polymer-based materials and etching techniques for dental enamel adhesion.
Main Results:
- Phosphoric acid etching to create microretention in dental enamel is the leading technique.
- Clinical success with this technique is highly dependent on the skill of the researchers.
- A new polymer system for dentine adhesion shows potential but is not yet commercially available and its long-term efficacy is uncertain.
Conclusions:
- Polymer-based materials are central to developing advanced adhesive dental restorative materials.
- The effectiveness of current enamel adhesion techniques, like phosphoric acid etching, is operator-dependent.
- Further research is needed to confirm the viability of new dentine-adhering materials for widespread clinical use.
