Comparative evaluation of coronal discoloration induced by two triple antibiotic revascularization protocols when used at varying depths of temporary sealing material at the end of varying time periods

摘要

Aim: The aim of this study is to evaluate and compare the coronal discoloration induced by two Triple antibiotic paste (TAP 1 and 2), when used with varying depths of 2 and 4 mm of temporary sealing materials at the end of 0, 3, and 6 weeks. Objectives: (1) To evaluate coronal discoloration induced by TAP-1 when the depth of the temporary restorative material is 2 mm below cementoenamel junction at the end of 0, 3, and 6 weeks. Materials and Methods: Forty extracted permanent maxillary central and lateral incisors or single-rooted tooth were collected and chosen for the study. They were then divided into two groups and each group was then subdivided into two subgroups. Results: Both the triple antibiotic paste showed discoloration but it reduced with increase in thickness of temporary cement. Conclusion: TAP 1 and TAP 2 both showed an increase in discoloration, greater discoloration was seen with TAP, containing minocycline. There was a steady change in the discoloration from 0 to 6th week. In both the groups, TAP 1 and TAP 2, there was a reduction in discoloration with increase thickness of the temporary restorative material.
