Özet

Objective: To investigate the persistence of staining after the use of chlorhexidine gluconate mouthrinse. Method and Materials: Twenty-four subjects (nine women and 15 men) who underwent periodontal therapy and were prescribed the use of 0,2% chlorhexidine gluconate mouthrinse participated in this study, Color values of maxillary central incisors, canines, and first molars were recorded at baseline; 3 days: and 1, 2, and 3 weeks of twice daily chlorhexidine gluconate use with a digital intraoral colorimeter according to the CiE L*a*jb* coordinates, Results: While color change (Delta E) values showed significant differences (P = .020) at different time points (10.1, 8.9, 8.9, 9.4, after 3 days and 1, 2, and 3 weeks, respectively), the duration of chlorhexidine gluconate use did not significantly affect the results (P = .873) (two-way ANOVA, Tukey test). No significant difference was found among Delta L* (P= .070), Delta a* (P = .169), and Delta b* (P = .691) values at any time point (one-way ANOVA), Measurements of baseline to day 3 differences showed significantly higher Delta E values than those at other time points (P < .05), but this change remained nonsignificant after 1, 2, and 3 weeks of chlorhexidine gluconate use (P > .05) (Tukey test), The highest visible staining occurred on the first molars at all time points (83%, 79%, 79%, and 96% after 3 days and 1, 2, and 3 weeks, respectively) compared to the other teeth evaluated, inclusion' The staining effect of chlorhe.xidine gluconate mouthrinse on natural dentition should be expected to he the highest in the first few days of use (Quintessence Int 2011..42.213-223)
