Statistical Analysis
Data were tabulated, and analyzed using the computer program SPSS (Statistical package for social science) version 17 to obtain descriptive statistics that was calculated in the form of frequency percentage
The statistical comparison between different groups was carried out using one of the following tests:-
1- Inter-group comparison of categorical data were performed by using chi square test (X2-value)
2- Freidman test: for comparison of more than two related groups with non-parametric data
A P value <0.05 was considered statistically significant. Results
This study is a randomized controlled clinical trial with a split mouth design. Sixty children were selected25 male (41.7%) and 35female (58.3%), their age ranged

At 3months, 26 teeth were succeeded, while two teeth showed minor failure (mild pain, and difficulty of eating). Only two teeth had major failure (crown lost). At 6 months 24 teeth were succeeded, two teeth had minor failure in the form of mild pain and difficulty of eating). Only four teeth showed major failure in form of crowns loss. On other hand, 25 teeth at 9 and 12 months were succeeded; no teeth demonstrated minor failure. While five teeth showed major failure of SSCs in the form of crown

Radiographical evaluation of SSCs (group I)
Only one tooth had physiologic root resotption at 6, 9, and 12 months. However, no teeth showed pathological signs in the form of pathological root resorption, bone resorption, carious lesion, and furcation involvement at the different follow up periods as seen in table (5) figure (17).
