Descriptive statistics showing a comparison between the change in root length and dentin thickness at baseline (immediately posttreatment) and at 6 months between groups I and II

Parameter	Blood clot Mean ± SD	PRF Mean ± SD	t-value	p-value
Root length	0.7000 ± 0.3545	0.7875 ± 0.2587	−0.564	0.582
Dentin thickness	0.2875 ± 0.1126	0.4500 ± 0.1309	−2.66	0.019*

SD denotes standard deviation; p-value represents the probability value p < 0.05 is considered significant
