Abstract
Materials and Methods Fifty-six premolars were used in this study and divided by two evaluations: 28 teeth for apical sealing ability and 28 others for bond strength. Each study was assigned randomly into two groups of fourteen teeth: Group-1, final irrigation with 17% EDTA; Group-2, with 0.5% chitosan nanoparticles. Each group was further divided into two groups of 7 each: Group-A, final irrigation was applied for 1 minute; Group-B, for 3 minutes. All teeth were obturated with epoxy resin-based sealer and gutta-percha. In the apical sealing ability study, the obturated teeth were immersed in 2% methylene blue and observed under a stereomicroscope (8x magnification). In the bond strength study, the teeth were tested using the push-out technique and observed under a stereomicroscope (40x magnification) to determine the failure type. Data from each evaluation were analysed with two-way ANOVA followed by the LSD test. Results Final irrigation using 0.5% chitosan nanoparticles produced the same apical sealing ability and bond strength as 17% EDTA (p > 0.05). A significant difference occurred between application times (p < 0.05). The failure type was observed predominantly as cohesive, and the least was adhesive. Conclusion Regardless of the final irrigation solution used, 3-minute application time produced greater apical sealing ability and push-out bond strength than 1-minute application time.
Highlights
Root canal irrigation is a crucial stage during root canal treatment since it can affect the root canal obturation; as a result, the success of root canal treatment can be achieved. e objective of this study is to evaluate the effect of 0.5% chitosan nanoparticles as a final irrigation solution with different application times on the apical sealing ability and the bond strength of root canal obturation
Other authors recommended the smear layer removal as it consists of microorganisms that can cultivate in the dentinal tubules [20]. erefore, the application time of the final irrigation solution is the essential factor in removing the smear layer to enhance the adhesion of root canal obturation; as a result, the success of root canal treatment can be achieved [21]
To date, no agreement occurred in the apt application time of final irrigation solution on the root canal dentin, which may enhance the apical sealing ability and bond strength of root canal obturation
Summary
Diatri Nari Ratih ,1 Nikita Ika Sari ,2 Pribadi Santosa ,1 and Nofa Mardia Ningsih Kaswati 3. E objective of this study is to evaluate the effect of 0.5% chitosan nanoparticles as a final irrigation solution with different application times on the apical sealing ability and the bond strength of root canal obturation. Erefore, the application time of the final irrigation solution is the essential factor in removing the smear layer to enhance the adhesion of root canal obturation; as a result, the success of root canal treatment can be achieved [21]. To date, no agreement occurred in the apt application time of final irrigation solution on the root canal dentin, which may enhance the apical sealing ability and bond strength of root canal obturation. Us, this present study aimed to evaluate the time-dependent effect of 0.5% chitosan nanoparticles as the final irrigation solution on the apical sealing ability and bond strength of root canal obturation Only a few studies are available in the literature that has investigated the application time of chitosan nanoparticles as final irrigation on apical sealing ability and push-out bond strength. us, this present study aimed to evaluate the time-dependent effect of 0.5% chitosan nanoparticles as the final irrigation solution on the apical sealing ability and bond strength of root canal obturation
