Tooth Discoloration Effect of BIOfactor Mineral Trioxide Aggregate: A 6-Month In Vitro Study

Abstract

The central objective of this research was to examine the color consistency of three materials, Biodentine (Septodont, France), Angelus MTA (Angelus, Brasil), and BIOfactor MTA (Imicryl, Turkey), when exposed to various irrigation solutions and to observe their impact on tooth discoloration. Each material was used to make sample cylinders (n = 18). After hardening, the samples were immersed for 24 h in either distilled water, 2.5% sodium hypochlorite (NaOCl), or 2% chlorhexidine gluconate (CHX). A spectrophotometer was used to measure the color changes. On the mandibular molars, access cavities were made in order to assess the discoloring impact of calcium silicate cements. In the pulp chambers of the teeth, Biodentine, Angelus MTA, and BIOfactor MTA were inserted (n = 17). Glass ionomer cement was used to seal the samples. Spectrophotometric measurements were made at five different intervals (the beginning, one week, one month, three months, and six months), after which color variance values were computed. The resulting information was statistically evaluated. In all solutions, Biodentine and BIOfactor MTA displayed similar ΔE values. When Angelus MTA was soaked in NaOCl, it discolored more than in CHX or distilled water. Distilled water and NaOCl both caused identical discoloration on all material groups when solutions were examined separately. With CHX, Biodentine changed colors more significantly. After a week and a month, all substances caused comparable tooth discoloration. Biodentine produced the most significant color shifts on teeth at the third and sixth months. Angelus MTA exhibited less color stability in NaOCl and Biodentine in CHX. While Biodentine induced significant discoloration, BIOfactor MTA only showed a moderate amount.
