Assessing the Effectiveness of Several Irrigating Solutions in Removing the Smear Layer from Primary Tooth Root Canals: A Scanning Electron Microscopic Study

Abstract: Background: Within the complex root canal architecture, calcified debris is removed mechanically, and organic debridement is dissolved chemically. An important role in the whole process is played by the irrigation technique, which significantly aids in the removal of germs from the intricate root canal structure. Numerous irrigation solutions, either alone or in combination with sodium hypochlorite, ethylenediaminetetraacetic acid (EDTA), citric acid, tetracycline, and chlorhexidine, have been thoroughly investigated at various doses. The current study was set out to assess and contrast the effectiveness of commonly used chemical agents with respect to their ability to remove the smear layer following instrumentation, as shown by scanning electron microscopy (SEM). Aim: The purpose of this in vitro investigation was to evaluate the effectiveness of hand instrumentation in the removal of the smear layer from the coronal, middle, and apical thirds of the root canals of primary teeth using 0.9% normal saline, 5.25% sodium hypochlorite, MTAD, and ginger extract as the final irrigant. Material and Method: After 40 human removed primary teeth were prepared to a 40# K file, they were randomly assigned to one of four groups (n=10), with the final irrigants being 0.9% Normal Saline, 5.25% Sodium Hypochlorite, MTAD, and Ginger extract. The amount of smear layer covering the dentinal surface of the decoronated teeth was measured after they were divided lengthwise into two halves. The Rome et al. scoring criteria were applied for taking SEM images, and the student t test, Chi-square test, and Kruskal-Wallis test were used to examine the data. Result: When comparing Biopure MTAD to other groups, an intergroup comparison revealed a statistically significant difference in all thirds (p<0.0001). Conclusion: Ginger extract is a herbal substitute for root canal irrigant in primary teeth, and Biopure MTAD is a successful method for removing the smear layer.
