Effect of Dentine Bonding and Laser on Prevention of Teeth Discoloration Produced by Gray Mineral Trioxide Aggregate and Triple Antibiotic Paste: A Comparative In vitro Study
Author(s): Farah Abdul Razzaq* and Anas F Mahdee
Aim: To evaluate the preventive efficacy of two dentine tubule occlusion methods (dentine bonding and laser) against discoloration caused by Gray Mineral Trioxide Aggregate (GMTA) and triple-antibiotic paste (TAP). Materials and methods: Sixty extracted human maxillary first premolar were used in this study. Access cavities were prepared and endodontic instrumentation was performed for the buccal canals. The specimens then were randomly divided into two groups (n=30) as GMTA or TAP groups. Each of these were further divided into 3 subgroups according to surface treatment for the pulp chamber walls into: dentine bonding (Bon), Er,Cr:YSGG laser(Las), or left without treatment as control (Con). The buccal canal totally filled with GMTA or TAP. The color measurements were performed from a specific region on the buccal surface by using VITA Easys.. Read More»
