Master Title
Evaluation of Antimicrobial Effect of Different Medicinal Herbs against Single Species of Enterococcus Faecalis and Candida Albicans (An in-vitro study)
Master Abstract
Summary and Conclusion
The aim of the present in vitro study was to evaluate the antimicrobial effect of differrent medicinal herbs against single species of Entercoccus faecalis & Candida albicans. Fifteen essential oils were extracted by Steam distillation method. screened for antimicrobial activity by the Agar Well-diffusion method, through the observation of the zones of microbial growth inhibition diameters. Also direct contact test was used to test the in vitro intracanal microbial reduction at 2 time intervals (24hrs and 72 hrs), using the 3 essential oils that exhibited the highest growth inhibition zone diameters. The oils tested were Tea tree oil(Melaleuca alternifolia), Cinnamon oil and Peppermint oil. In the direct contact test, sixty single rooted human teeth were inoculated with the appropriate suspension of C.albicans and E.faecalis and incubated for 24hrs at 37°C. Afterwards the root canals were divided into 3 groups, each was filled with one of the essential oils tested. The root canals were sampled and the colony forming units (CFU/ml) were counted after 24 hrs and 72hrs incubation. The agar diffusion test results showed that, there was a higly significant difference in the antimicrobial activity of the selected essential oils among the tested microorganisms (p<0.001). Tea tree oil, Peppermint oil and Cinnamon oil showed the highest inhibition zone diameters against both E.feacalis and C.albicans. The direct contact test results revealed that, the 3 essential oils tested showed considerable reduction in the mean CFU/ml of both test organisms either after 24 hrs or 72 hrs. Statistical analysis showed that, there was a significant decrease in the mean CFU/ml of C.albicans among the Tea tree oil group after 72hrs (1.02 ± 0.59) when compared to that after 24hrs (3.76 ± 1.26), p <0.05. Also statistical analysis revealed that regarding Candida albicans, there was a significant decrease in the mean of CFU/ml after 24hrs among the Peppermint group (2.04 ± 0.7) when compared to that of Tea tree group (3.76 ± 1.26), p <0.05. While after 72 hrs, mean CFU/ml significantly decrease with the Tea tree oil (1.02 ± 0.59), compared to Peppermint group (1.87 ± 0.03), p <0.05. Meanwhile, regarding Enterococcus faecalis there was a higly significant decrease in the mean CFU/ml at 72 hrs among Tea tree oil (0.2 ± 0.45) when compared to Cinnamon oil (3.95 ± 1.91), p < 0.05. Surprisingly, no viable colonies were observed at 72 hrs among the Peppermint group, which was considered a significant decrease when compared to Cinnamon oil (3.95 ±1.91), p <0.05. Under the conditions of the present study, It can be concluded that Tea tree, Peppermint and Cinnamon oils showed a considerable antimicrobial effect against C.albicans and E.feacalis. Medicinal herbs may offer a new source of antimicrobial agents for use.
PHD Title
Evaluation of the Biocompatibility, Bioactivity and Cytotoxicity of a Recent mineral based Bioceramic sealer (In Vivo and In Vitro study)
PHD Abstract
Summary and Conclusion
This study aimed to evaluate and compare the in-vivo biocompatibility, bioactivity and cytotoxicity of BioRoot RCSTM in parallel to MTA Fillapex and AH Plus sealers. For the in-vivo Biocompatibility evaluation, Polyethylene tubes containing the freshly mixed test materials, were implanted in the subcutaneous tissue of 32 Wistar rats. After 7, 14, 30 and 60 days, the animals were sacrificed and the implants with surrounding tissues were processed for routine histological analysis. For bioactivity evaluation sealer filled root discs were immersed in Phosphate bufferd saline for 1 week and 28 days. Morphological and elemental analysis was performed using Scanning electron microscopy and Energy Dispersive X-ray analysis. MRC 5cells were exposed to several dilutions of the extracts of the tested sealers and cytotoxicity was evaluated using MTT assay at 24 hours and 72 hours in reference to controls. Results revealed that, BioRoot RCS exhibited rapid recovery of inflammation similar to controls. Regarding Bioactivity, BioRootTM RCS and MTA Fillapex were comparable in regards to their tendency to deposit bioactive precipitations (Hydroxy apatite). Regarding Cytotoxicity, BioRootTM RCS showed to be cytocompatible with proliferative potential. Thus, within the limitations of this study it can be concluded that, BioRoot RCS is considered a Bioactive and biocompatible sealer with acceptable tissue tolerance
