The Comparison of the Anti-inflammatory Efficacy of Phytochemical Extracts in Punica granatum and Lawsonia inermis Among Patients Diagnosed With Chronic Periodontitis.

Abstract

Introduction The oral cavity is the gateway to the human body. Periodontitis is a common inflammatory condition affecting the oral cavity and a known etiological cause of tissue destruction, discomfort, and halitosis. Pomegranate (Punica granatum)and henna (Lawsonia inermis) are herbs known to mankind from timeimmemorial whose extracts are proven to fight inflammation. The current study was done to evaluate the phytochemical anti-inflammatory efficacy of Punica and Lawsonia in patients with chronic periodontitis and test the potency of herbal mouthwashes in fighting the inflammatory condition affecting the oral cavity using distilled water as a control group. Materials and methods A double-blinded randomized control trial was conducted on 60 patients who were recruited and divided into three groups, in which 20 patients were prescribed with pomegranate (Punica: n=20) mouthwash and 20 patients with henna (Lawsonia: n=20) mouthwash along with distilled water (n=20). All patients were randomly allocated using the coin toss methodand advised to use the prescribed mouthwash for a period of two weeks. Unstimulated saliva was collected before using the mouthwash, and salivary enzymes such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) and their levels were assessed spectrometrically using the infrared spectrophotoscopy (IFSC) method. Each patientwas assigned a mouthwash and recalled after two weeks. Unstimulated saliva was again collected, and salivary activity levels of enzymes AST, ALT, and LDH were analyzed after using mouthwash in a similar method as done before. Later on, the salivary levels of enzymes AST, ALT, and LDH were compared before and after the usage of mouthwashes. Statistical significance was seen in the salivary enzymatic activity of AST, ALT, and LDH before and after using Punica and Lawsonia mouthwashes due to their potent phytochemical action in fighting inflammation. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS)22 (IBM SPSS Statistics, Armonk, NY). The Shapiro-Wilk test was used to determine the normality and significance; intragroup comparison was done using the Wilcoxon signed-rank test and Mann-Whitney U test. Intergroup comparison was done using the Kruskal-Wallis test. Results Punica patients had much lower levels ofsalivary AST and ALT (p<0.001) and a decrease in LDH (p=0.002) after the usage of mouthwash for a period of two weeks. Also, patients using Lawsonia as herbal mouthwash had reduction in the values of AST (p=0.001) and LDH (p=0.003) and prominent reduction in ALT (p<0.001) aftera period of two weeks. But in the case of patients using distilled water, there was an increase in the salivary enzymatic activity of AST and ALT, which was statistically significant (p<0.001), and LDH (p=0.006)depicting the disease progression even after using mouthwash for the given time period of two weeks. Conclusion This study demonstrated that both Punica and Lawsonia were effective in reducing the inflammation in patients diagnosed with chronic periodontitis. However, when intergroup comparison was done, the anti-inflammatory efficacy was superior in Punica with significant reductionin the parameters such as ofAST, ALT, and LDHwhen compared to Lawsoniaowing to its potent phytochemical constituency in cutting down the inflammation. Hence,Punica can be used as an implicatedeffective anti-inflammatory herbal mouthwash.
