Assessment of the antibacterial activity of Catharanthus roseus leaf extract on periodontal pathogens, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Prevotella intermedia: An In vitro study

Abstract: Plant extracts and phytochemicals having antimicrobial characteristics could be immensely beneficial in medicinal treatments. The present study deals with the effect of Citrus lemon extract over Periodontal pathogens which are primary etiologic factors for periodontal diseases. The current study took into account periodontal pathogens such as Prevotella Intermedia, Aggregatibacter Actinomycetemcomitans, and Porphyromonas Gingivalis. Chlorhexidine is a gold standard antimicrobial agent with a wide antibacterial activity that is commonly used for chemical plaque management. When used for an extended period, however, chlorhexidine is known to stain. As a result, the alternatives are to be explored such as herbal-based agents that can be used regularly. Using the microdilution process and the culture method, the antibacterial effect of citrus lemon extract against periodontal pathogens was assessed using the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and zone of inhibition (ZOI). According to the findings of this study, citrus lemon extract can be used as a natural supplement for treatment purposes.

ABSTRACT Aim To evaluate the in vitro antimicrobial activity of three commercially available intense sweeteners against two common periodontal pathogens Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. Materials and methods Three commercially available intense sweeteners namely saccharin, aspartame and sucralose were obtained and powdered. Necessary concentrations of the sweeteners were prepared by mixing them with an inert solvent. The antimicrobial efficacy was assessed using agar well diffusion technique. Statistical analysis was done using one-way ANOVA followed by Tukey's post hoc test. p-value < 0.05 was considered statistically significant. Results All the three sweeteners showed significant antimicrobial activity against the periodontal pathogens tested. Sucralose containing sucralose showed maximum zone of inhibition, against Aggregatibacter actinomycetemcomitans. Saccharin and aspartame containing saccharin and aspartame respectively, showed maximum zone of inhibition, against Porphyromonas gingivalis. Conclusion All the sweeteners used in this study have demonstrated significant antimicrobial activity. Therefore, these sweeteners could be recommended as an ideal alternative to sucrose. Clinical significance Dental caries and periodontal diseases are ubiquitous diseases of mankind caused by microorganisms. Dental caries is caused by sucrose. By altering the source like intense sweetener we can combat caries as well as with its antimicrobial properties against periodontopathic bacteria, we can reduce prevalence of periodontal diseases.
