Abstract
Background and aims. Dental plaque and gingivitis were controlled by administration of chemical agents such as
chlorhexidine (CHX) which is recognized as a gold standard of chemical agents. The aim of this study was to compare the
effects of two mouthwashes (0.2% CHX and Kin Gingival) on clinical parameters.
Materials and methods. A total of 88 subjects were included in this interventional‒experimental study. The subjects
were divided into two groups of 44 (group 1: 0.2% CHX and group 2: Kin Gingival). The study involved no mechanical
plaque control methods. Patients used the mouthwashes twice a day for two weeks. Clinical parameters included plaque
index (PI), gingival index (GI), probing depth (PD) and bleeding on probing (BOP), which were measured before and after
the use of mouthwashes. The results were analyzed by Man-Whitney U and chi-squared tests. Statistical significance was
set at P < 0.05.
Results. The results indicated that PI, GI and PD significantly decreased in group 2 (Kin Gingival) in comparison with
group 1 (0.2% CHX) (P < 0.05). However, the two mouthwashes did not differ significantly from each other in relation to
BOP (P > 0.05).
Conclusion. Based on the results it can be concluded that Kin Gingival and 0.2% CHX mouthwashes decrease the clinical
parameters in patients significantly. However, Kin Gingival is more effective than 0.2% CHX, which might be attributed to
the synergic antibacterial potential of Kin Gingival ingredients like sodium fluoride.
