Abstract

17% EDTA is a chelating agent used to clean the smear layer. Novel silver citrate (NSC) is a new material with the same use, while 0.2% chitosan nanoparticles are a material that has been widely studied. The agitation technique influences smear layer cleanliness by optimizing the penetration of irrigation material. Agitation techniques are sonic and ultrasonic agitation techniques; each has its advantages and disadvantages. The research objective is to evaluate the effect of final irrigation materials, agitation techniques, and a combination of both on the cleanliness of the smear layer in the apical third of the root canal.Forty-five premolars were prepared with a rotary instrument. Samples then randomly divided into 3 experimental groups (n=15). Group 1 used 17% EDTA, group 2 used NSC, and group 3 used 0.2% nanoparticle chitosan. Each group was divided into three subgroups (n=5) with subgroup A using manual agitation technique, subgroup B sonic agitation, and subgroup C ultrasonic agitation. The samples were sectioned and then examined under SEM with 5000x magnification to evaluate the cleanliness of the smear layer. The results from SEM were scored and then analyzed using Chi-Square test (IBM SPSS Statistics 29.0.1.0).Final irrigation agents of 17% EDTA, NSC, and 0.2% chitosan nanoparticles resulted in the same cleanliness of the smear layer (p˃0.05). The ultrasonic agitation technique showed better cleanliness of the smear layer than the sonic agitation and manual agitation techniques (p˂0.05). The final irrigation material combined with agitation techniques resulted in the same cleanliness of the smear layer (p˃0.05).

Abstract

Background: The smear layer may interfere with the penetration of the root canal sealer. Final irrigation is known to improve chelating agents' ability in smear layer removal. This study aimed to compare the effect of various materials and final irrigation techniques on the penetration depth of bioceramic silers in the apical third of the tooth.Method: This study used 45 premolars that were prepared with a rotary instrument and then randomly divided into three experimental groups (n=15). Group 1 used 17% EDTA as the final irrigation material, group 2 used Novel Silver Citrate, and group 3 used 0.2% nanoparticle chitosan. Each group was divided into three subgroups (n=5), with subgroup A using manual agitation technique, subgroup B using sonic agitation, and subgroup C using ultrasonic agitation. The teeth were then obturated using a bioceramic sealer. Teeth then cut vertically for observation and measurement  sealer penetration using a stereo microscope with a magnification of 30x followed by observation using SEM at 1000x magnification. data where analyzed using a two-way ANOVA followed by an LSD Post Hoc test, with a significance level of 95%.Result: Two-way ANOVA showed significant differences in materials, techniques, and material-technique interactions (p<0,05).Conclusion: This study concludes that there is an effect of material, technique, and material-technique interaction of final irrigation on the penetration of bioceramic sealer into the dentinal tubules, Combination of 0.2% chitosan nanoparticles and sonic agitation as material and final irrigation technique resulted in the most longest penetration of bioceramic sealer into dentinal tubules.
