Clinical Assessment of SDF Effect in Arresting Dental Caries in Deciduous Teeth.

Objectives: Current research was done to evaluate the effectiveness of 38% silver diamine fluoride (SDF) on carious lesions in deciduous teeth. Materials and Method: The study included kids who had at least one carious lesion in accordance to the International Caries Detection and Assessment System II. A 38% SDF (FAgamin, Tedequim Company, Córdoba, Argentina) solution was applied directly to the lesion on the deciduous teeth as per the manufacturer's instructions. A follow-up evaluation was performed after one, three, and six months. Clinical results were used to assess the efficacy of SDF. The obtained data were statistically evaluated. Result: When it came to halting dental caries in primary teeth, 38% SDF was 92% effective. Conclusion: In conclusion, 38% SDF can be used to effectively stop caries in primary teeth.

Effect of Root Canal Taper on the Ability of Endodontically Treated Teeth using the TruNatomy and Protaper Next File Systems to Resist Fracture.

Objectives: This research was done to evaluate how the root canal taper affects the Endodontically Treated Teeth (ETT) prepared with the TruNatomy and Protaper Next file systems in terms of fracture resistance. Materials and Method: Forty recently extracted mandibular premolar teeth were used in this research, which was classified into four groups at random. Groups 1a and 1b used TruNatomy 4% and 6%, respectively, while groups 2a and 2b used the Protaper Next 4% and 6% file systems, respectively. The root canals were cleaned, shaped, and sealed using cold lateral compaction. The root canals were then fixed in standardized autopolymerizing acrylic resin blocks and tested for vertical root fracture using a universal testing machine. Newtons were used to measure the forces needed to cause fractures. Data were statistically analyzed. Results: In comparison with other groups, group 1a (TruNatomy 4%) displayed greater fracture resistance (423.322.43 Newtons), and group 2b (Protaper Next 6%) displayed the least fracture resistance (264.512.76 Newtons). Conclusion: Protaper Next file system had lower fracture resistance than TruNatomy file system. With the use of greater taper instruments, a notable decrease in the fracture resistance of ETT was observed.
