Cytotoxicity of oregano essential oil and calcium hydroxide on L929 fibroblast cell: A molecular level study.

Introduction: The purpose of antimicrobial agents is to eliminate the microorganisms without causing toxicity to host cells. This study aimed to assess the cytotoxic effect of oregano essential oil on L929 fibroblast cells.

Materials And Methods: L929 fibroblast cells were exposed to four different concentrations of oregano essential oil (25-200 μg/ml) and calcium hydroxide (1 mg/ml).

Antibacterial Activity of Various Intracanal Medicament against , and : An Study.

Aim: The aim of this study was to evaluate and compare the antimicrobial efficacy of triple antibiotic paste (TAP), calcium hydroxide, and Odontopaste which are used as intracanal medicaments against , Streptococcus mutants, and .

Materials And Methods: Antibiotic sensitivity testing was done using agar well diffusion method of the following intracanal medicaments: Group 1: TAP (Ciprofloxacin, metronidazole, and doxycycline mixed in a ratio of 1:1:1; Group 2: Calcium hydroxide paste; Group 3: Odontopaste; Group 4: Sterile saline (0.9%) as a negative control.

Evaluation of tissue inflammatory response of four intracanal medicament - An animal study.

Aim: The aim of the study was to evaluate the tissue inflammatory response of origanum vulgarae, omeprazole, triple antibiotic paste (TAP), and calcium hydroxide in an animal model.

Materials And Methods: Seventy Five male Wistar rats were randomly divided into four experimental groups and one control group: Group 1: control ( = 15), Group 2: 0.25 mg origanum vulgarae/1 ml of cellulose ( = 15), Group 3: 2 mg omeprazole/1 ml of distilled water ( = 15), and Group 4: 1 mg TAP/1 ml of distilled water ( = 15), Group 5: 16 mg calcium hydroxide/1 ml of distilled water ( = 15).

Efficiency of new custom-made pulse oximeter sensor holder in assessment of actual pulp status.

Aim: This study aims to assess the diagnostic accuracy of new custom-made pulse oximeter sensor holder in assessment of actual pulp status with three pulp sensibility tests.

Materials And Methods: Seventy-nine single canal teeth requiring endodontic therapy was included in the study. The tooth that was requiring root canal treatment was tested with heat test, cold test, electric pulp test, and pulse oximeter.

Chemical constituent, minimal inhibitory concentration, and antimicrobial efficiency of essential oil from oreganum vulgare against : An study.

Aim: The purpose of this study was to determine the chemical composition of oregano essential oil, minimal inhibitory concentration (MIC) and to assess its antimicrobial efficiency against .

Material And Methods: Gas Chromatography and Mass Spectrometry (GC-MS) was used to determine the chemical composition of essential oil from oreganum vulgare. Broth dilution and agar diffusion method was used to evaluate the MIC.

Removal of toxic heavy metal lead (II) using chitosan oligosaccharide-graft-maleic anhydride/polyvinyl alcohol/silk fibroin composite.

The present work was aimed to investigate the efficiency of novel chitosan oligosaccharide-graft-maleic anhydride(COS-g-MAH)/Polyvinyl alcohol (PVA)/silk fibroin (SF) composite for removing the toxic heavy metal lead (II) ion from aqueous solution by batch adsorption studies. Initially the chitosan oligosaccharide-graft-maleic anhydride copolymer has been prepared by utilizing ceric ammonium nitrate as an initiator and the optimised graft copolymer was then used for synthesizing COS-g-MAH/PVA/SF composite. The prepared samples were analyzed through FTIR and XRD studies.

Comparative evaluation of tensile bond strengths of total-etch adhesives and self-etch adhesives with single and multiple consecutive applications: An in vitro study.

Aim: This study evaluates the effect of single and multiple consecutive applications of adhesives on the tensile bond strength. The currently available adhesives follow either the total-etch or the self-etch concept. However, in both techniques the uniformity and thickness of the adhesive layer plays a significant role in the development of a good bond.
