简要总结
AIM
· The aim of the present study was to investigate retention and stability of micro-etched molar bands and conventional molar bands in a prospective, randomized, controlled trial.
MATERIALS AND METHODOLOGY
This study with a split-mouth design will be conducted in the Department of Orthodontics and Dentofacial Orthopedics, Faculty of Dental Science, Dharmsinh Desai University, Nadiad, Gujarat.
A total of 75 patients resulting in a total of 300 molar bands cemented, which included 150 micro-etched bands and 150 conventional bands with side allocation determined through Block Randomization.
Band retention will be checked at 4-week intervals, and loose bands will be deemed as failures. The date of failure will be recorded as accurately as possible; if not identifiable, the date of the patient’s department visit will be noted.
The study will track all cases either to the end of treatment or a maximum period of 1 year and 6 months (540 days), after which molar bands will be censored for patients whose bands have not failed.
STATISTICAL ANALYSIS
The statistical analysis was conducted using Chi-Square test using SPSS 8.0 to evaluate the influence of various explanatory variables on band failure.
Failure rates of microetched and conventional bands are compared amongst subjects and among bands.
