ABSTRACT:-
Objective: To compare the palatal bone density at the suture to determine any correlation present in the success or the failure of cases. Method: The digital CBCT (Cone bean computed tomography) Scan of patients between the age group of 17-25 with permanent dentition is taken. Patients who had undergone mini screw assisted rapid palatal expansion were selected from the database of the Department of Orthodontics and Dentofacial Orthopaedics in D Y Patil University School of Dentistry, Navi Mumbai. This is a retrospective study depending on the previous records. CBCT’s of the selected patients are checked for their bone density in grey scale units at the sutural level and classified into D1, D2, D3 and D4 to check if there is any correlation between the success and the failure of MARPE (mini screw assisted rapid palatal expansion) cases. Result: The ROC (Receiver operating characteristic) curve shows that when the grey scale unit of the bone density is less than 610.5 there is a possibility of suture opening and more than that, there are chances for procedure failure. This is in respect to the area of the suture. Conclusion: In miniscrew assisted rapid palatal expansion, there are various predictors to determine the success of the treatment however there is not sufficient proof to confirm a diagnostic method as a pre requisite for the procedure. The parameter used in the study was the palatal bone density near the suture and the surrounding area. However this study has to be continued with a larger sample size with various age groups, as age also plays an important role in the suture separation as it is directly associated with the suture maturation stages.
