Chemical plaque control, an adjunct to mechanical approaches, could improve the maintenance of patients with different types of periodontitis. Chlorhexidine, the gold standard in chemical plaque control, might have some side effects; the most determining one is tooth discoloration. Anti-discoloration systems (ADS) have been added to minimize brownish tooth discoloration. This study aimed to evaluate the staining potential and clinical efficacy of chlorhexidine with and without ADS in patients with chronic periodontitis.

In this randomized controlled trial, 46 patients with chronic periodontitis were randomly allocated to two groups. Each patient used 10 mL of mouthwash A (CHX without ADS) or B (CHX with ADS, including sodium metabisulfite and ascorbic acid) twice a day for two weeks. After a two-week interval, they used the second mouthwash. At the beginning and the end of each two-week cycle, plaque index (PI), bleeding on probing (BoP), and staining index were recorded. 

Results

There was no significant difference between mouthwash A and B in the reduction of BoP and PI. The staining index was significantly lower after rinsing with mouthwash B compared to mouthwash A.

CHX mouthwash containing ADS has similar efficacy in microbial plaque control and reduction of BOP as CHX without ADS, with the advantage of lower stain formation on tooth surfaces in patients with chronic periodontitis.

The aim of the present study was to determine the most effective oral hygiene method in fixed orthodontic patients.

A total of 125 patients who had recently started their orthodontic treatment and had not received oral hygiene instructions were randomly assigned to 5 groups (n = 25): verbal instructions (V), verbal instructions plus pamphlet (V + P), verbal instructions plus video film (V + F), verbal instructions plus the use of disclosing agents (V + D), and pamphlet plus the use of disclosing agents (P + D). One week after the installation of orthodontic appliance, plaque index (PI) and gingival index (GI) were recorded and oral hygiene instructions were provided. One week and 4 weeks after oral hygiene instructions, PI and GI were recorded again.

PI and GI showed significant decreases in 5 groups after 1 week and 4 weeks (P ˂ 0.05). No statistically significant differences were detected between the 5 study groups in terms of plaque reduction after one week. However, after 4 weeks PI values were significantly lower in V + D group compared to P + D group. Regarding GI, V + D method resulted in a significantly lower GI than P + D after 1 week and 4 weeks.

To sum up, all the oral hygiene motivation methods applied in this study can be effective in decreasing PI and GI. However, it appears that the best way is the verbal oral hygiene instruction plus the use of disclosing agents.
