A Comparative Study of Ion Diffusion from Calcium Hydroxide with Various Herbal Pastes through Dentin

Abstract

AimThe aim of this study was to evaluate the diffusion ability of ions through dentinal tubules of different nonalcoholic calcium hydroxide-containing herbal pastes and compare it with the calcium hydroxide paste prepared with saline.Materials and methodsA total of 36 single-rooted premolar teeth were used in this study. The tooth crowns were removed and the root canals were prepared. Depending on the vehicle to be used for preparing calcium hydroxide pastes, six groups were made: Group I: Ca(OH)2 saline paste (control group), group II: Ca(OH)2 papaya latex paste, group III: Ca(OH)2 coconut water paste, group IV: Ca(OH)2 Ashwagandha (Withania somnifera) paste, group V: Ca(OH)2 Tulsi (Ocimum tenuiflorum) paste, and group VI: Ca(OH)2 garlic (Allium sativum) paste. After biomechanical preparation, calcium hydroxide herbal paste dressings were applied and sealed with resin-based cement. The teeth were placed in containers with deionized water, and the pH of the water was measured at regular intervals over 3, 24, 72, and 168 hours.ResultsWe observed that all herbal pastes allowed the diffusion of ions, but pastes prepared with Ashwagandha and papaya latex showed more ion diffusion after 168 hours and marked increase in pH, depicting better support for calcium hydroxide action.ConclusionWe conclude that Ashwagandha and papaya latex allow better diffusion of calcium hydroxide through den-tinal tubules, thus enhancing its action, and advise its use as a vehicle for placing intracanal medicament.How to cite this articleDausage P, Dhirawani RB, Marya J, Dhirawani V, Kumar V.

Diffusion of calcium hydroxide through dentinal tubules of retreated root canals: An in vitro study

“…Besides permitting diffusion of the Ca(OH) 2 , the vehicle can enhance the antimicrobial capacity of the paste. [ 21 ] According to Gomes et al ,[ 22 ] chlorhexidine can be used as a vehicle for attempting an increase in the antimicrobial property to be effective against aerobic and facultative anaerobic microorganisms, Gram-positive and Gram-negative microorganisms, yeasts, and viruses.…”

Evaluation of Propolis as Intracanal Medicament against <i>Enterococcus faecalis</i>

“…Attempts to improve the effectiveness of calcium hydroxide pastes have been proposed using chemicals such as p-chlorophenol and Chlorhexidine [37]. Dausage et al also supported this finding in 2017, who reported that the diffusion ability of calcium hydroxide ions through dentinal tubules is facilitated by the addition of herbs [38]. It has been recognized that long-term exposure to calcium hydroxide alone decreases the strength of root dentin and changes its physical properties, while a mixture of calcium hydroxide with other materials decreases it is an adverse effect on root dentine [39].…”

Evaluation of the Antimicrobial Efficacy of Herbal Extracts Added to Root Canal Sealers of Different Bases: An In Vitro Study

“…8 Owing to their safety and ability to combat new developing drug resistant pathogens, herbal preparations are always welcome in presentday science. 9 There are insufficient scientific reports that indicate the antimicrobial activities of herbal extracts mixed with endodontic root canal sealers. Hence, the aim of the study was to evaluate and compare the antimicrobial efficacy of endodontic sealers of different bases mixed with herbal extracts.…”
