Evaluation Of Efficacy Of Chemo-mechanical Method Of Caries Removal Using BRIX- 3000 Compared To Conventional Excavation With Burs- A Randomized Controlled Trial – Original Research

Introduction and Aim
The study was designed as a randomized double-blind trial to evaluate the efficacy of chemo-mechanical method of caries removal using BRIX 3000 as compared to conventional excavation with burs.

Methods
The double blind randomized control trial was performed using a split mouth design where patients with bilateral deep carious lesion underwent treatment with Brix 3000 on one side and high speed bur excavation with aerotar on the contralateral side. This was performed to compare the efficacy of Brix 3000 with the conventional high speed caries excavation using aerotar. Group 1 (G1 = 67 teeth) chemomechanical removal with Brix 3000 and Group 2 (G2= 67 teeth) high speed bur excavation with aerotar. The criteria assessed were the time (T) required for each protocol to be completed and pain perceived by the patient at the end of caries excavation.

Results
All statistical analysis were done using (SPSS) version 17.0 statistics software. Independent sample t test and Mann Whitney U test were one to analyze the data.

Conclusions
Though time taken for caries excavation was more using BRIX than the high speed procedures, there was less or no pain while caries excavation using BRIX 3000 along with more patient comfort and cooperation during procedure. From the current study, it was observed that BRIX 3000 can be considered as an effective alternative/adjuvant for caries removal in deep carious lesions as compared to aerosol inducing high speed rotary techniques.
