Screening of Hallucinogenic Compounds and Genomic Characterisation of 40 Anatolian Salvia Species.

Introduction: Salvia, an important and widely available member of Lamiaceae family. Although comparative analysis on secondary metabolites in several Salvia species from Turkey has been reported, their hallucinogenic chemicals have not been screened thoroughly.

Objective: This study provides LC-MS/MS analysis of 40 Salvia species for screening their psychoactive constituents of salvinorin A and salvinorin B.

Effect of the angle of apical resection on apical leakage, measured with a computerized fluid filtration device.

Objective: We determined the effect of the angle of apical resection on apical leakage using a computerized fluid filtration meter with a laser system and a digital air pressure regulator in 46 extracted single-rooted human teeth. Orthograde endodontic treatment was performed. The root canals were prepared up to a size 50 K-type file with 17% EDTA solution (Roth International, Chicago, IL) and 5% NaOCl solution as the irrigant.

Evaluation of smear layer removal after use of a canal brush: an SEM study.

Objective: The objective of this study was to evaluate smear layer removal after using the new CanalBrush (Coltene/Whaledent GmbH+Co. KG, Germany).

Study Design: Twenty extracted maxillary anterior teeth were randomly divided into 2 equal groups.
