Comprehensive Assessment Of Intracoronal Stains Induced Via Triple Antibiotic Paste, Mineral Trioxide Aggregate And Calcium Hydroxide Powder Combined With Aquatic Solution Of Chlorhexidine– An In Vitro Study

Abstract

Tooth discoloration caused by various materials and agents causes internal stains, rendering the visual outcome of the pulp-treated
tooth unappealing. Thus, a continuous impingement of agents in dentinal tubules causing tooth discoloration is expected to be the
primary focus of this study. Furthermore, some speculated that tooth discoloration may not be caused by tubule penetration but rather
by endodontic material remnants in the pulp chamber that darken over time and transmit their shade through hard tissues. Sixty
premolars were chosen and randomly assigned to one of four groups, one of which was a control group. Four different agents were
used to obtain internal stains. These samples were then sealed in distilled water at 37°C for three months using restorative Glass
Ionomer Cement. All measurements were taken with a Spectrophotometer at the start and after 3 months. After 3 months of incubation,
all intracanal agents induced intracoronary stains. After three months of incubation, the following values were collected: group I, group
II, group III, and group IV. When compared to the other groups, the MTA group (group II) induced the most stains.
