Background: Platelet-rich fibrin is a second generation platelet concentrate enhances tissue healing and is in predominant use as a barrier membrane in periodontal regeneration. However, a normal PRF membrane has rapid degradability (1-2 weeks). Myristica fragrans (nutmeg) has been found to have antiprotease property. It was hypothesized if this property helps in inhibiting degradation of PRF. Aim: To assess whether nutmeg has any effect in inhibitingdegradability of PRF membrane and to compare the degradability of PRF at different concentrations (200mg, 100mg, 50mg) of ethanolic and crude extracts of nutmeg. Materials and Methodology: PRF was procured from 30 ml blood from 5 different donors were cut to equal sizes into 35 pieces. They were measured at baseline and dropped in 7 sets of ependorphs containing PBS, PBS containing 200 mg, 100mg and 50 mg crude extract of nutmeg, PBS containing 200 mg, 100mg and 50 mg ethanolic extract of nutmeg. After 1 week the PRF were retrieved and measured. The percentage of remaining PRF was calculated and data analysed. Result: It was found that there was a difference in percentages of remaining PRF between all the groups when compared to the control group, out of which, crude extract of nutmeg 200 mg group alone had a significantly lesser \% of remaining PRF than the control. All ethanolic extract groups had a significantly greater \% of remaining PRF when compared to that of the control. Conclusion: Nutmeg is effective in inhibiting the degradation of PRF membrane.

Background: There has been an increased use of natural products as medicament in endodontic treatment due to the increased adverse effect observed in chemical products used. The natural products used aims to disinfect the root canal and provide a sterile environment as efficiently as the comparable chemical products. Aim: To compare the antibacterial efficacy of cinnamon extract and calcium hydroxide as intracanal medicament against E. fecalis. Materials and Methods: The study is an in vitro randomized controlled study conducted on 40 single rooted permanent teeth. The study sample was divided into two groups- cinnamon extract as intracanal medicament and calcium hydroxide. The intracanal medicament was placed for 7 days. The outcome was measures using colony forming units per ml. Statistical analysis was done using Mann-Whitney\’s test to compare between the two groups. Results: Cinnamon extract intracanal medicament showed higher antibacterial efficacy as compared to calcium hydroxide. (p=0.002). Conclusion: Cinnamon extract showed better antimicrobial efficacy against E. feacalis as intracanal medicament as compared to calcium hydroxide.

Aim: The aim of the present study is to screen the ethanolic extracts of medicinal herbal drugs against oral microbes. Objective: In this study, 3 medicinal herbs were evaluated for antimicrobial activity against five common oral bacteria as a screen for potential candidates for the development of natural antibiotics. Methods: Ethanolic extracts of medicinal herbs were tested for activity against Enterococcus faecalis, Lactobacillus acidophilus, Streptococcus mutans, and Streptococcus sanguis grown in brain heart infusion (BHI) broth. A broth microdilutionassay was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). A disk diffusion assay was performed by inoculating bacterial cultures on BHI agar plates with paper disks soaked in each of the medicinal herb extracts. Results: The ethanolic extracts of many of the 3 medicinal herbs showed antimicrobial activity against the five types of pathogenic oral bacteria. The extracts of Caralluma fimbriata, Hemidesmus indicus, and Grape seed effectively inhibited the growth of oral bacteria and showed distinct bactericidal activity. Conclusion: These results suggest that alternative medicines with proven antimicrobial effects, such as Caralluma fimbriata, Hemidesmus indicus, and Grape seed may be useful for the treatment of dental diseases.

Aim \& objective: The aim of this study was to evaluate acetyl cholinesterase inhibitory activity of Acacia catechu ethanolic seed extract to introduce a new source for management of Alzheimer\’s disease. Background: Alzheimer\’s disease is a complex, multifactorial, progressive, neurodegenerative disease primarily affecting the elderly population and is estimated to account for 50\–60\% of dementia cases in persons over 65 years of age. It is likely that the inhibition of acetyl cholinesterase by Acacia catechu ethanolic seed extract that is rich in flavonoids and antioxidants may aid in the protection of neurodegenerative disorders and ultimately Alzheimer\’s disease. Methods: Anti cholinesterase activity is determined by adopting In vitro standard protocol. Results: According to the obtained results, the inhibitory activity (IC50 values, \μg /ml) of extracts was 204.38 \± 2.54 \μg/ ml. Conclusion: The results indicated and confirmed the traditional use of Acacia catechu ethanolic seed extract for management of central nervous system disorders. It showed the moderate activity in inhibition of acetyl cholinesterase at various concentrations. However, further investigations on identification of active components in the extracts are needed.
