ABSTRACT
OBJECTIVES: Histatin, with its anti bacterial, anti protease, and wound closure stimulating property might influence the pathogenesis of periodontal disease. This study assessed the presence of histatin in gingival crevicular fluid (GCF); the levels of salivary and GCF histatin in periodontal disease. MATERIAL AND METHODS: It was a cross sectional study that included systemically healthy forty five subjects (22 males and 23 females) between the age group of 20 to 45 years. Based on Gingival Index (Loe and Silness ,1963) and Russell's Periodontal Index they were grouped as 15 healthy (Group 1), 15 gingivitis (Group 2), and 15 periodontitis (Group 3) subjects. Whole pooled unstimulated saliva was collected by asking the patient to spit in a sterile container and GCF samples were collected using a micropipette from all the subjects. Histatin levels were assessed using Enzyme Linked Immunosorbent Assay (ELISA). The intergroup comparison was done by ANOVA and Mann Whitney U Test was done for pair wise comparison. RESULTS: The results of this study show that histatin is present in saliva and gingival crevicular fluid. When the salivary histatin levels were compared it was found that the levels of histatin increase from health to periodontitis but the levels of histatin in the gingival crevicular fluid and saliva had no correlation with severity of periodontal disease as there was no statistically significant difference between the three groups. CONCLUSIONS: It can be concluded that histatin cannot be used as a potential marker of periodontal disease. Key words:Periodontal disease, histatin, gingival crevicular fluid, saliva, gingival index, periodontal index, enzyme linked immunosorbent assay.
ABSTRACT
OBJECTIVE: to evaluate the effect of a pomegranate-containing mouthrinse on plaque, determine whether it has any adverse effects, and evaluate its antibacterial properties against selected periodontopathogens in vitro. METHOD AND MATERIALS: thirty periodontally healthy volunteers, randomly divided into three groups, refrained from all mechanical oral hygiene measures for 4 days and used one of the randomly assigned mouthrinses (A, pomegranate; B, chlorhexidine; or C, distilled water [placebo]) twice daily. The Plaque Index (PI) was assessed at days 0 and 5. Adverse effects were also evaluated. Pomegranate extract was tested against Aggregatibacter actinomycetemcomitans (A.a.), Porphyromonas gingivalis (P.g.), and Prevotella intermedia (P.i.). RESULTS: in all groups, the PI significantly increased from the baseline to day 5 (P < .1). The pomegranate mouthrinse created no adverse effects. There was a statistically significant difference (P < .05) between the chlorhexidine and placebo rinse and the pomegranate and placebo rinse, but no statistically significant difference was found between the chlorhexidine and pomegranate rinse with respect to the PI. Pomegranate extract showed inhibition of all three strains of periodontopathogens at various concentrations. CONCLUSION: these results indicate that the pomegranate mouthrinse has an antiplaque effect. Pomegranate extract is efficacious against A.a., P.g., and P.i. strains in vitro. Pomegranate mouthrinse should be explored as a long-term antiplaque rinse with prophylactic benefits.
