Objective: This study tried to explore the preventive effect of zinc citrate-containing dentifrices on oral diseases based on their gingivitis reducing effect by measuring and comparing the changes of gingival-periodontal indices and dental plaque in each time period.Methods: A total of 120 adults with mild to moderate gingivitis were selected and divided into experimental group and control group (60 adults per group). Using experimental and control dentifrices containing respectively zinc citrate and just dental-type silica, we measured and recorded Calculus, Papillary Marginal Attachment (PMA), Gingival, Patient Hygiene Performance (PHP), and Plaque index at four time points (before, and 1, 2, 4 weeks after, oral examination) over the study period. Results: One week after the examination, statistically significant gingivitis reducing effect was found in all indices except for Calculus index in the experimental group. At 2 and 4 weeks after the examination, gingivitis was also significantly reduced in the experimental group (p<0.05). Conclusion: Zinc citrate-containing dentifrices have a remarkable effect on reducing gingivitis and mitigating bad breath.
