Table 4 Spearman correlation between the light-curing tip (n = 200) condition and the percentage reduction in power and radiant emittance
From: Effect of damage or contamination to the tips of 200 light-curing units
Condition | Power Reduction (%) | Radiant Emittance Reduction (%) |
|---|---|---|
Contamination r-value p-value | 0.22070 0.0017 | 0.28626 < 0.0001 |
Physical Damage r-value p-value | 0.27422 < 0.0001 | 0.36650 < 0.0001 |
