AbstractWebsite

Introduction: Compared to synthetic herbicides, natural products with allelochemical properties can inhibit weed germination, aiding agricultural output with less phytotoxic residue in water and soil. Objectives: To identify natural product extracts of three Cassia species; C. javanica, C. roxburghii, and C. fistula and to investigate the possible phytotoxic and allelopathic potential. Methods: Allelopathic activity of three Cassia species extracts was evaluated. To further investigate the active constituents, untergated metabolomics using UPLC-qTOF-MS/MS and ion-identity molecular networking (IIMN) approach was performed to identify and determine the distribution of metabolites in different Cassia species and plant parts. Results: We observed in our study that the plant extracts showed consistent allelopathic activity against seed germination (P < 0.05) and the inhibition of shoot and root development of Chenopodium murale in a dose-dependent manner. Our comprehensive study identified at least 127 compounds comprising flavonoids, coumarins, anthraquinones, phenolic acids, lipids, and fatty acid derivatives. We also report the inhibition of seed germination, shoot growth, and root growth when treated with enriched leaf and flower extracts of C. fistula, and C. javanica, and the leaf extract of C. roxburghii. Conclusion: The present study recommends further evaluation of Cassia extracts as a potential source of allelopathic compounds in agricultural systems. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Nahass, "Biological evaluation of indirect restorations in endodontically treated posterior teeth with deeply located proximal margins following deep margin elevation versus surgical crown lengthening: a randomized controlled trial.", Clinical oral investigations, vol. 28, issue 1, pp. 24, 2023. Abstract

OBJECTIVE: The current clinical trial was conducted to evaluate the effect of proximal indirect restorations in endodontically treated posterior teeth with deeply located margins following deep margin elevation compared to surgical crown lengthening.

MATERIAL AND METHODS: Deep proximal cavities in endodontically treated posterior teeth were randomly assigned into two groups; deep margin elevation (DME) or crown lengthening (CL). The clinical attachment level (CAL), probing depth (PD), bleeding on probing (BOP), crestal bone level (CBL), and secondary caries were evaluated at the baseline, 1, 3, 6, 9, and 12 months.

RESULTS: A total of 20 proximal cavities were included in the study; there was no significant difference between the two groups regarding mean CAL values at the baseline and 1 month, while there was a significant difference between the two groups in all other periods. Regarding the PD, there was no statistical significance between the two groups except at 9 and 12 months, where CL showed higher mean PD values than DME. There was no statistically significant difference in BOP or CBL between the two groups.

CONCLUSIONS: DME and CL are considered clinically successful with favorable biologic responses.

CLINICAL RELEVANCE: The deep margin elevation approach could provide a more conservative solution when relocating deeply seated cervical margins in a more coronal position. DME reduced the number of visits and time needed for the restoration of endodontically treated teeth. Surgical crown lengthening remains a gold standard procedure in the re-establishment of the supracrestal tissue attachment, especially in cases where cervical margins are beyond the elevation capacity.
