Hypothesis
The tooth/resin bond would be adversely affected by simulated microwave disinfection, independently of the different treatments to the glossy ridge laps.
Conclusion
Simulated microwave disinfection significantly decreased the tooth/resin impact strength.
Supporting Evidence
- Microwave disinfection decreased the impact strength in all treatments.
- Control and monomer etched specimens had lower impact strength compared to bur abrasion and bur grooving treatments.
- All treatments showed statistically significant differences when comparing non-disinfected and disinfected specimens.
Takeaway
This study found that using microwaves to disinfect dental materials can weaken the bond between teeth and acrylic resin.
Methodology
Eighty specimens were tested for impact strength after being subjected to different treatments and microwave disinfection.
Limitations
The study is limited in predicting the effect of other variables involved in the investigation.
