Objectives: This study aimed to compare the coronal discoloration related to the application of two coronal sealing materials: Bioceramic (BC) root repair material (RRM) putty and mineral trioxide aggregate (MTA). Materials and methods: A total of 16 patients (divided into two subgroups, each one included 8 patients) had undergone regenerative endodontic procedures (REPs). Disinfecting the canals was achieved by the application of the double-antibiotic paste (DAP) “metronidazole and ciprofloxacin” to exclude minocycline discoloration effect; after 3 weeks, the medicament was removed, apical bleeding was induced till the formation of blood clot in the root canal, and then a coronal sealing was created. Bioceramic RRM putty was used in eight patients, while gold standard “MTA” was used in another eight patients. Finally, resin modified glass ionomer (RMGI) was applied followed with resin composite matching the shade of the treated teeth. Shades were measured immediately after procedures and through organized follow-up (3, 6, 9, and 12 months). Data were collected according to Commission International de I’Eclairage (CIE-LAB) and then ΔE values were calculated. A two-way statistical analysis of variance was performed depending on Student’s t and Chi-square tests at 95% (p = 0.05). Results: Coronal discoloration accompanied with MTA was clinically perceptible (ΔE > 3.3) through all periods. Coronal discoloration was slightly recognized in the BC group. However, there was no significant difference between the used two materials through studied periods (p > 0.05). There was incrementally increasing of discoloration through sequential organized follow-up periods. Conclusion: As a result of this study, BC RRM putty could be a good alternative material to MTA through REPs. Clinical significance: Pulp REPs are predictable therapies, but discoloration is still considered as a one of the most unfavorable complications; so, this study highlights on this outcome to obviate it.
