Objective: The aim and objective of this study was to evaluate the effect of Hiora mouthwash versus Chlorhexidine mouthwash for the treatment of gingivitis. Methods:The study population was comprised 30 gingivitis patients. The patients were randomly categorized into two groups of 15 patients in each group. Group A was given Chlorhexidine mouthwash and Group B was given Hiora mouthwash. Pre-operative measurements such as plaque index (PI), gingival index (GI), and probing depth (PD), and loss of attachment (LA) were measured. Oral prophylaxis followed by the prescription of mouthwash was done. The patients were recalled for a review after 15 days, and post-operative measurements were recorded. Results:From the statistical analysis in the experimental Group A and Group B, the mean values of PD, LA, GI, and PI were found to be significantly lower in the post-operative period than the pre-operative mean values. At the end of 15 days, almost comparable reduction in the amount of plaque and gingivitis was found in both Group A and Group B. Hence, the differences in efficacy of these two mouthwashes were non-significant. Conclusion:Hiora and Chlorhexidine mouthwashes were equally effective in the treatment of gingivitis.

Periodontal diseases require treatment at an early stage to prevent further damage and aggravation of the disease. The most commonly seen periodontal diseases are gingivitis and periodontitis. Animals have contributed a major role in studying the different periodontal diseases and providing a proper treatment. Periodontal diseases are either induced in these experimental animal models or can be seen naturally. Different drugs are tested on the animals induced by the disease to find the most effective treatment for that particular disease. Different animals such as mice, rats, pigs, rabbits, hamsters, and rodents are used for the periodontal research. Different animals show a different reaction while some animals show no reaction. Each animal has its own advantages and disadvantages. The use of large animals brings a limitation in the due to its housing difficulties. Animals for periodontal research are chosen depending on their similarity with that of human anatomy and physiology. The use of these animals will help to replicate the disease seen in humans in a better and more accurate way. This will improve the treatment outcome and the prognosis of the disease. The drugs used can, hence, give a better idea about the effect it would have on the human body depending on the effects it shows on the animal models. Hence, the use of appropriate animals for the periodontal research is important to design a better treatment for these diseases. Hence, animal models play an important role in the periodontal research.

It is of interest to evaluate the anti-inflammatory, anti-oxidant effect and cytotoxicity of Ocimum sanctum (an Indian herb, Thulsi) intra oral gel in combating periodontal diseases. Hence, 2% of O. sanctum gel was prepared with Carbopol940 soaked in purified water containing 0.2% w/v sodium benzoate overnight. Hydroxy proplyl methyl cellulose (HPMC) solution was mixed with propylene glycol using using tissue homogenizer. Anti-oxidant effect was analyzed using DPPH radical assay and anti-inflammatory effect was assessed using the inhibition of albumin denaturation assay. Ocimum sanctum gel with various dilutions from10 micro litres to 50 micro litres showed exponential increase in percentage of inhibition from 60.9 to 72.2 exhibiting antioxidant activity. The anti-inflammatory effect of Ocimum sanctum gel showed comparatively equivalent effect with standard diclofenac gel with values ranging from 76.6 for 50 micro liters of Ocimum sanctum gel and 89.6 for standard gel at 50 micro liters. Ocimum sanctum showed less toxicity towards brine shrimp nauplii. Thus we show that Ocimum sanctum gel showed potent anti-oxidant and anti-inflammatory effect and less toxic to brine shrimp nauplii as a promising agent for the treatment of periodontal diseases.
