Hypothesis
Is there a direct relationship between articulating paper mark area and applied occlusal load?
Conclusion
The study found that articulating paper mark area does not reliably indicate the applied occlusal load.
Supporting Evidence
- 600 marks were statistically analyzed to determine the relationship between load and mark area.
- 14 out of 66 comparisons showed no significant difference in mark size and load.
- The study suggests that similar sized marks do not indicate similar loads.
Takeaway
This study shows that just because a mark is big doesn't mean it has a lot of force behind it; marks can be misleading.
Methodology
A uniaxial testing machine applied loads to epoxy dental casts with articulating paper, and the mark areas were analyzed.
Limitations
Only one type of articulating paper was used, and the study did not replicate the complexities of the human oral environment.
