盲法说明
Observation:
Each patient will be followed up on periodic base for progress evaluation and integrity checks, as well as root resorption will be evaluated using CBCT images taken before and after the intrusion.
Ethical considerations:
An informed consent form (attached copy) that explains every step in the research will be given and discussed carefully with the patient and his/her parents before participation in the study and should be signed freely. The objectives of the study will be discussed and explained with the patients and / or their guardians and they will receive a copy of the consent form as well.
Data management and analysis:
The data will be collected, tabulated, and statistically analyzed using Statistical Package for Social Sciences (SPSS program, version 18, Inc., Chicago, III).
