Abstract

Background: Perforation can occur while performing root canal treatment. Biodentine has been made utilizing MTA (mineral trioxide aggregate) as a base, and claims to improve its properties in aspects such as physical property, durability, and handling, as well as its many other applications in restorative dentistry. The chemical components of SDF (silver diamine fluoride) have been suggested to have the following benefits: fluoride aids in remineralization and prevention, silver salts induce dentin sclerosis/calcification, and exhibit germicidal actions. It works by occluding dentinal tubules thus helping in preventing microleakage. This study aims to focus on the use of SDF on Biodentine and MTA as perforation repair material using a confocal microscope. Methods: Mandibular molars will be selected for the study. The study will be divided into 4 groups: Group 1: Biodentine without application of 38% SDF; Group 2: Biodentine with the application of 38% SDF; Group 3: MTA Angelus without application of 38% SDF; and Group 4: MTA Angelus along with the application of 38% SDF. An artificial perforation 2 mm in diameter will be made directly in the middle of the pulpal floor. 38% silver diamine fluoride (FAMAGAIN) will be applied on the walls of the perforation according to the manufacturer’s instructions for the experimental groups (Groups 2 and 4). In the four groups, Biodentine will be applied in groups 1 and 2 and MTA will be applied in 3 and 4 (perforation repair material). To evaluate the sealing capacity of perforation material in this study, we will use the average values of coronal dye leakage at the perforation site and Escobar’s criteria, which are used to assess the infiltration proportions. Conclusions: It is expected that application of 38% of silver diamine fluoride on MTA Angelus and Biodentine may show better sealing ability than MTA Angelus and Biodentine alone.
