“…H-files had a significantly higher amount of dentin removal at the coronal (P<0.001) and the middle (P<0.001) section than Fanta AF files. In overall root section, a statistically significant difference was present between groups (P<0.001), as shown in Table (2).…”

Aim: To assess canal shape, dentin thickness, and risk of perforation after using rotary Fanta AF baby files versus manual Hedstrom (H) files in root canal instrumentation of extracted second primary molars. Materials and methods: Twenty-six extracted second primary molars were randomly assigned to two groups; in Group (I): Molars were instrumented by Rotary Fanta AF baby files while in Group (II): Molars were instrumented by Manual H-files. The amount of dentin removal, canal shape, and risk of perforation were evaluated by cone-beam computed tomography (CBCT) comparing the pre to post instrumentation images. Fracture resistance after instrumentation was assessed with a universal testing machine. Results: Regarding the overall comparison of the amount of dentin removal on the mesial and distal walls of the distal canal, a significant difference was present between Fanta AF baby files and H-files (P=0.013) and (P<0.001) respectively. Where H-files removed a higher amount of dentin with mean ±SD (0.10±0.04) and (0.13±0.05) than Fanta files (0.08±0.04) and (0.05±0.02). However, a non-significant difference was observed regarding the shaping ability (P=0.691), the incidence of risk of perforation (P=0.680), and the fracture resistance (P=0.189). Conclusion: The Fanta AF baby files seem to be more effective in preserving dentin thickness than H files, and it can be utilized as a better alternative in root canal instrumentation in primary molars.

“…This may be explained by the heat treatment of Ni-Ti rotary files which leads to an increase in the file’s flexibility, renders higher torsional resistance, adapts the file to the contour of the primary root canal, and aids less straightening during instrumentation [ 37 , 38 ]. Moreover, the high centering ability of the Fanta AF™ Baby file group could be related to working in a crown-down technique with rotation motion [ 39 ]. The decreased centering ability of manual K-file may be linked to the stainless-steel alloy used in its manufacturing which requires more force to bend; this will exert and lead to more cutting on the outer curvature of the canal, which results in eccentricity [ 40 ].…”

Background Pediatric rotary file systems were developed to solve manual file limitations. With many systems available, it may be tricky to select the most appropriate one. Aim to assess & compare Kedo-S Square, Fanta-AF™-Baby rotary files with manual K-file concerning removed dentin amount, canal transportation, centric ability & root canal taper using CBCT in primary anterior teeth. Design Extracted Seventy-five upper primary anterior teeth with intact 2/3 root length were collected and divided into three groups based on root canal instrumentation, group-I: prepared using K-file, group-II: prepared using Kedo-S Square, and group-III: prepared using Fanta AF™ Baby file. The teeth were imaged with CBCT before & following canal instrumentation. Then, the removed dentin amount was calculated at each root-canal level. The Kruskal-Wallis test was utilized to statistically analyze study data. Result The difference among the three groups was highly statistically significant at cervical & apical thirds concerning dentin thickness changes on both mesial & distal sides following canal preparation with the least removed dentin in the Kedo-S Square group(P < 0.0001). Regarding transportation & centering ability, a non-significant difference between the three groups was found. 80% of the Fanta AF™ Baby group had good-tapered preparation compared to the Kedo-S Square (72%) and K-file (40%) groups(P < 0.05). Conclusion Kedo-S Square was preferable to Fanta-AFTM-Baby & manual K-files in primary root canal preparation.

“…Then, all canals were instrumented using Kidzo rotary file system (Elephant dental supplies LTD, China) in a lateral brushing motion following the manufacturer’s instructions. The rotary files were used with an Endo-Mate DT endodontic motor (NSK, Tokyo, Japan) at 350 RPM and 2.5 N/cm torque in the following order: # 25/0.04 and # 30/0.04 [ 25 ]. Ethylenediaminetetraacetic acid (EDTA) gel (17%) (Meta Biomed Co. Ltd, Chungbuk, Korea) was applied to always lubricate the files during the biomechanical preparation.…”

Objectives The complex root canal anatomy of primary teeth keeps it very tricky to attain appropriate cleansing by biomechanical instrumentation, so obtaining an obturating material with excellent antimicrobial properties is a challenge in current clinical pulpectomy practice. So, this study aimed to assess the clinical and radiographic performance of zinc oxide-ozonated olive oil as a primary root canal filling material. Materials and methods Ninety non-vital primary molars in children ranging from 4 to 8 years were allocated into three groups in which root canals were filled with zinc oxide-ozonated olive oil, zinc oxide-olive oil, and zinc oxide-eugenol (ZOE) according to each group after pulpectomy procedure. Clinical and radiographic evaluations were done at 3-, 6-, and 12-month follow-up periods. Statistical analysis was performed for the collected data. Results All study groups showed a significant improvement regarding clinical signs and symptoms during follow-up periods. Ozonated-olive oil group revealed a significant increase in furcation radiodensity and a decrease in periodontal ligament space at 3-, 6-, and 12-month follow-up intervals compared to other groups. Conclusion Zinc oxide-ozonated olive oil and zinc oxide-olive oil paste had shown good clinical and radiographic success for primary teeth pulpectomy. Clinical relevance The intricate torturous primary root canal anatomy, in addition to the child’s negative behavior, interferes with the complete debridement, so the long-lasting antibacterial effect of the primary root canal filling material aids in the pulpectomy success.
