Comparing Plaque-Reducing Effectiveness of Green Tea-Propolis Toothpaste (Atomy®) and Dual Zinc Arginine Toothpaste (Colgate Total Advanced®) - A Randomized Clinical Trial

Introduction: Plaque is the chief precursor of many periodontal diseases, and its effective control is crucial for maintaining oral health. While mechanical plaque removal remains the cornerstone of oral hygiene, chemical adjuncts can enhance biofilm disruption and prevent microbial accumulation. Natural agents such as green tea, with its antioxidant, anti-inflammatory, antibacterial, anticariogenic, and anti-plaque properties, and propolis, a resinous substance with broad antimicrobial and anti-inflammatory activity, have shown promise as supportive measures in periodontal care. In contrast, zinc ions, known for their antimicrobial effects, and arginine, which potentiates zinc?s antibacterial action, are widely incorporated into conventional oral hygiene products. Therefore, this study aimed to compare the effectiveness of toothpaste containing green tea and propolis with that of toothpaste formulated with dual zinc and arginine. Aims and objectives: To compare the antiplaque efficiency of toothpaste containing a combination of green tea and propolis (ATOMY ®) with that of dual zinc arginine containing tooth paste (COLGATE TOTAL ADVANCED ®) Materials and methodology: Single Blinded, Randomized controlled clinical trial, of 100 Patients, divided into 2 groups, patients within age group of 18 to 25, patients are randomly allotted into 2 groups Group A-50 (ATOMY ®) and GROUP B-50 (COLGATE TOTAL ADVANCED ® )Patients were allotted based random sequence generator ( random.org.) followed by chit method and adverse reactions if any were also noted, using adverse reaction reports. Results: A total of 100 patients were assessed at baseline and after 2 weeks using the plaque index and OHI-S index. In Group A, the average reduction from the baseline score is 0.51 (0.5), while in Group B, it is 0.74 (0.67). The decrease in OHI-S scores in Group A is 0.97 (0.88), compared to 1.55 (1.26) in Group B. Conclusion: In conclusion, both toothpaste formulations were effective in reducing plaque and improving oral hygiene within two weeks; however, the dual zinc-arginine toothpaste demonstrated greater reductions in Plaque index and OHI-S scores compared to the green tea-propolis toothpaste, indicating superior efficacy in biofilm control and oral hygiene improvement.
