Evaluation and Comparison of Dentin Thickness, Centering Ability, Canal Transportation, and Instrumentation Time of Pro AF Baby Gold and Pedoflex Files in Primary Root Canals Using a Cone Beam Computed Tomographic Analysis: An In Vitro Study.

Introduction: Pediatric rotary systems have the advantage of improved canal centricity and conservative canal preparation with better obturation quality. Pro AF Baby Gold and Pedoflex files are two exclusive pediatric rotary file systems that were introduced in recent times. Aim and objective: The aim of the present study is to compare and evaluate the dentine thickness, centering ability, canal transportation, and instrumentation time of Pro AF Baby Gold and Pedoflex files using cone beam computed tomography (CBCT). Materials and methods: A total of 40 extracted human primary molar teeth with a minimum 7 mm root length were included in the study and randomly divided into two groups: group I, Pro AF Baby Gold; group II, Pedoflex files. Teeth were imaged preoperatively with CBCT, then root canal preparation was done in both groups with respective files, followed by postoperative CBCT imaging to evaluate the dentin thickness, centering ability, and canal transportation of both groups. Instrumentation time was noted using a stopwatch. Results: There is a statistically significant difference in the instrumentation time; Pedoflex took a shorter time when compared to Pro AF Baby Gold files. Regarding canal transportation, there was no significant difference between the two files, with Pedoflex showing a better value than the other files. Regarding centering ability, there was no significant difference between the two files, with Pro AF Baby Gold having a better value than the other files (p < 0.001). Conclusion: From the findings of our present study, it was found that both systems were able to effectively shape curved root canals in terms of canal transportation and centering ability.

Effect of Different Iron Supplements on Color Stability of Nanocomposite Restorative Materials.

Physical development and growth are significantly influenced by adequate nutrition. Enamel, dentin, and dental pulp are among the tissues that contain iron, which is regarded as a necessary element for human health. The disadvantages of the available iron drops include bad taste and black discoloration of primary teeth. In areas that are decalcified and hypomineralized, this discoloration is more noticeable. Therefore, efforts are being made to create iron drops that have a more pleasant taste and minimal adverse effects (i.e., no or minimal tooth discoloration). Liposomes are minuscule vesicles made of the bilayer of phospholipids that can encase both hydrophilic and hydrophobic drugs to boost their effectiveness and lessen side effects (color staining). Therefore, the goal of the study is to compare the color stability of cosmetic materials with that of pediatric liposomal iron supplements and regular pediatric iron supplements.
