Cleanliness efficacy and effect on dentin microhardness of a novel plant extract irrigant

Abstract

Objective: This study was done to evaluate the effect of the prepared Moringa oleifera-based root canal irrigant compared to conventionally used irrigants on the microhardness of root dentin and smear layer removal. Materials and methods: One hundred freshly extracted teeth with single root were divided into 5 groups according to the irrigant used: group 1, saline; group 2, Moringa oleifera; group 3, Moringa oleifera + chlorhexidine; group 4, chlorhexidine; and group 5, sodium hypochlorite. Root canal preparation was done using Protaper universal system till size F5 using one of the irrigants after each file. Fifty teeth were prepared to measure dentin microhardness, while the remaining fifty were prepared for evaluation of the remaining debris and smear layer using stereomicroscope and scanning electron microscope (SEM) in each third of the canal. Results: Chlorhexidine alone and combined with Moringa oleifera showed higher microhardness values in apical and coronal parts. In the middle parts, chlorhexidine followed by Moringa oleifera showed the highest results. SEM examination showed that none of the used irrigants has the ability to completely remove smear layer. However, Moringa oleifera group showed the least amount of smear layer on canal wall. Conclusions:Moringa oleifera is a promising final irrigant solution alone or combined with chlorhexidine throughout the instrumentation. Moringa oleifera was proved to have a high effect as a chelating agent.

Comparison of the push-out bond strength of AH Plus sealer to dentin after using different herbal irrigation solutions as the final rinse

“…In recent years, there has been growing interest in the use of herbal irrigation solutions with pharmaceutical properties. Because of the cytotoxicity of most irrigation solutions and their direct contact with tissues, there is a great tendency to use biologic medication extracted from natural plants in endodontic treatment [ 39 ]. Previous studies which compared the antimicrobial activities of different irrigation solutions used different concentrations of NaOCl from 0.5 to 5.25 [ 40 , 41 ].…”

Effect of Irradiation with 980-nm Diode Laser on the Microhardness of Young and Old Root Canal Dentin after Treatment with Chemical Solutions

“…This may explain the higher levels of microhardness of old teeth compared to young teeth (30) . Moreover, lower microhardness may weaken the root structure and limit the sealer ability to adhere to the root dentin walls and seal them (31) .…”

The Effect of a Novel Silver-Citrate Root Canal Irrigation Solution (BioAkt), Ethylenediamine Tetraacetic Acid (EDTA), and Citric Acid on the Microhardness of Root Canal Dentin: A Comparative In Vitro Study

“…Informed consent was obtained from patients before extraction. Immediately after extraction, the teeth were rinsed using running water, then immersed and disinfected in 2.5% NaOCL for one hour [8]. After that, the collected teeth were stored in a tightly closed plastic bottle, containing distilled water, inside a refrigerator at 4°Celsius, for no more than six months [10].…”

“…Interestingly, the microhardness of root dentin has been the main concern of recent studies while assessing the action of up-to-date chelating agents. Vickers hardness number (VHN) testing has been used for this purpose due to its accuracy and reliability in addition to the pyramidal indentation technique through which the mechanical characteristics of a very thin disc can be analysed [4,8,9].…”
