Aim: To evaluate the microhardness and change in color of root dentin using Punica granatum, sodium hypochlorite, chlorhexidine and normal saline as an endodontic irrigant and to implement their use in field of dentistry. Materials and Methods: 60 single rooted anterior teeth extracted due to periodontal and orthodontic reasons were collected. All the samples were decoronated to achieve constant length of 14mm. Patency of root canal was established using 10k file and working length was determined 1mm short of the file length. Each canal was prepared till F3 protaper. After preparation the samples were randomly divided into 4 groups: Group 1: Saline (Control); Group 2: 5\% Sodium Hypochlorite; Group 3: 2\% Chlorhexidine; Group 4: 5\% Punica granatum (pomegranate peel extract). After grouping the samples were longitudinally sectioned. One half of the tooth sample was used for microhardness testing using Vickers microhardness indentor and the other half of sample was used for color change evaluation using spectrophotometer after irrigation with the test solutions on day 1 and day 7th post irrigation. Results: The mean microhardness in all four groups decreased comparatively at post as compared to pre and the decrease was evident highest in sodium hypochlorite followed by chlorhexidine, pomegranate and saline the least. In regard to color change sodium hypochlorite, chlorhexidine and pomegranate all showed visible color changes after 7 day of irrigation with pomegranate showing the highest color change. Higher lightness was shown in Group 2 i.e., sodium hypochlorite whereas redness was seen more in Group 4 i.e., pomegranate and yellowish tint was more visible in Group 3. Conclusion: 5\% Punica granatum has showed negligible effect on microhardness of dentin but showed maximum color change when compared to chlorhexidine, sodium hypochlorite and saline.

Aim: This study aimed to evaluate the antibacterial activity of Calcium hydroxide, Azadirachta indica (Neem), Ocimum tenuiflorum (Tulsi) and Punica granatum (Pomegranate) gels as intracanal medicaments against Enterococcus faecalis. Methodology: Crude extracts of Pomegranate peel, Neem leaves and Tulsi leaves were used to determine MIC following which gels of 5\% neem, 10\% tulsi and 10\% pomegranate were prepared. Forty-eight single rooted human premolars were procured and inoculated with E.faecalis for 7 days. Specimens were then randomly distributed into 4 groups.

Group I- Calcium hydroxide

Group II- 5\% A. indica (Neem) gel

Group III- 10\% O. tenuiflorum (Tulsi) gel

Group IV-10\%

P. granatum (Pomegranate) gel The experimental gels were then introduced into the samples and were sealed at both ends. The antimicrobial activity of medicaments was assessed by measuring CFU/ml at the end of 1, 3 and 5 days. Results: Calcium hydroxide showed the maximum antibacterial activity (5.3X104 CFU/ml) followed by Pomegranate gel (5.4 X104 CFU/ml) with no statistically significant difference between them. Similarly, no statistically significant difference was observed between the mean CFU/ml values of the neem (10.2 X104 CFU/ml) and tulsi gel (10.2 X104 CFU/ml). However, pomegranate gel showed statistically significant antibacterial activity when compared to Neem and Tulsi. (Table 1, Table 2, Table 3, table 4) (Figure 1). Conclusion: Calcium hydroxide showed the best antibacterial activity against E.faecalis. Among herbal gels, pomegranate showed the maximum antibacterial activity, however, further in-vivo research is required for it to be used as a sole intracanal medicament clinically.
