Summary
Dentine bonding is affected by humidity. Without a rubber dam, the intraoral environment mimics high-humidity climates, potentially impacting dental adhesion results.
Area of Science:
- Dental materials science
- Biomaterials engineering
Background:
- Dentine adhesion is crucial for dental restorations.
- Environmental factors like humidity and temperature significantly influence dentine bonding.
- The precise impact of intraoral humidity on bonding is not well-understood.
Purpose of the Study:
- To investigate the influence of relative air humidity and temperature on dentine bonding.
- To assess how factors like rubber dam use, breathing, and tooth drying affect the intraoral environment.
Main Methods:
- Six experiments were conducted to evaluate environmental variables.
- Investigated were: rubber dam application, high/low relative humidity, nose/mouth breathing, and tooth drying.
- Temperature and relative air humidity were measured under various conditions.
Main Results:
- Without a rubber dam, no significant temperature differences were found between breathing and drying methods (mean 27.7°C ± 1.5°C).
- Relative air humidity in the dental surgery showed a statistically significant difference.
- With a rubber dam, intraoral humidity and temperature closely matched dental surgery conditions.
Conclusions:
- The intraoral environment without a rubber dam is comparable to high-humidity climates.
- This finding has implications for the predictability and success of dentine bonding procedures.
- Controlling intraoral humidity is essential for optimizing dental adhesion outcomes.
