  Background and Aim : Tooth discoloration of anterior teeth is an important esthetic problem for both the patient and dentist. One of the causative factors in this regard is placing intracanal medicaments. The aim of this study was to compare discoloration potential of calcium hydroxide vs. triantibiotic paste when being placed into the pulp chamber space .

  Materials and Methods : Forty extracted upper human central incisors, with no caries or crack were selected for this study. Digital photographs were taken from the buccal aspect of all specimens under a standard situation. RGB/HSB variables were recorded, using Photoshop software,. Then access cavities were prepared and canals enlarged using #1, #2, and #3 gates glidden drills and peeso reamers. The teeth were randomly divided into two experimental groups. In group A calcium hydroxide and in group B triantibiotic compound was placed in pulp chamber space. Then access cavities were sealed with a self-curing glass ionomer cement. After incubation of the samples for four months digital photographs were taken in the same standard situation and RGB/HSB variables were recorded. Pre- and post-treatment data were compared and analyzed using paired-t and independent t-tests .

  Results : Both experimental groups showed a significant discoloration after four months in their labial surfaces. (p<0.05) Discoloration changes in calcium hydroxide group was much more than that of triantibiotic group but the difference was not significant (p>0.05 ).

  Conclusion : Tooth discoloration was indicated following use of both calcium hydroxide and triantibiotic dressing within the pulp chamber space, but the difference between two groups was not statistically significant.(p>0.05 ).
