Effects of an alexidine mouthwash on dental plaque and gingivitis in humans over a six-month period.

The primary purpose of this study was to determine the safety and effectiveness of alexidine in the control of plaque and gingivitis in humans. For six months, 207 persons who continued their usual oral hygiene procedures rinsed twice daily with 15 ml of either alexidine (0.035% or a placebo solution. At the 30-day examination and for the remainder of the study, a statistically significant reduction in plaque between the two groups was recorded. Gingivitis was reduced in persons in both the test and placebo groups (the former always had the greater reduction), and a statistically significant difference was found at the 30-day and 90- day examinations. The preponderance of data indicates that, under the described experimental conditions, the alexidine rinse was effective in reducing both indicators of oral health and it may have important therapeutic potentials.

The effect of an alexidine mouthwash on dental plaque and gingivitis.

The alexidine mouthrinse used in this study (CP-101) is effective in reducing plaque. There was a reduction in gingivitis after 6-months use but not at a statistically significant level. An extrinsic brown stain occurred at a significant level on the teeth of participants using the active mouthrinse. Blood and urine laboratory results indicated that alexidine can be safely used over a 6-month period.

The effect of an alexidine mouthwash on plaque and gingivitis.

A clinical study was conducted on the effects of an alexidine or placebo oral rinse on plaque and gingivitis. Forty-two male subjects rinsed for 54 days while continuing toothbrushing. This was followed by 4 days of mouthrinsing only. The alexidine mouthrinse significantly reduced the plaque index when used in conjunction with toothbrushing and also when brushing was discontinued. The gingivitis results were inconclusive.

Tooth staining effects of an alexidine mouthwash.

The primary purpose of this study was to determine the amount of tooth staining produced by an alexidine mouthrinse. One hundred and eighty subjects rinsed twice daily for 1 month with either 15 ml of alexidine (0.035%) or a placebo solution. Prior to the study, the subjects were classified according to their smoking, coffee and tea drinking habits and these factors were subsequently considered in the analysis of the stain scores. Additionally, the effects on staining of a prior prophylaxis and the use of a fluoridated toothpaste during the study were determined. Upon termination of the study, subjects utilizing the active mouthrinse manifested a greater degree of staining than placebo users. The amount and intensity of the stain due to alexidine were not influenced (increased) by smoking, tea or coffee drinking habits. A prior prophylaxis did not reduce the staining propensity of alexidine users. The method of scoring developed can be used to assess the degree of tooth staining induced by antiplaque agents.

The effect of surface adsorption and staining reactions on the antimicrobial properties of some cationic antiseptic mouthwashes.

The phenomenon of surface adsorption appears fundamental to the antiplaque activity of the cationic antiseptics. Moreover, reaction with chromogenic material is relevant to the local side effect of staining. The purpose of this investigation was to determine how such local reactions affect the antibacterial activity of some of these antiseptics. The minimum inhibitory concentration (MIC) of commercial mouthrinses containing alexidine, cetyl pyridinium chloride, chlorhexidine gluconate and hexetidine against Oxford staphylococcus (NCTC 6571) and Escherichia coli (NCTC 10418) was established by tube dilution. The effect on the MIC values against O. staphylococcus of adding polymethylmethacrylate polymer or against E coli of adding a standard tea solution was then measured. The zones of inhibition around acrylic blocks soaked in the respective antiseptics, with and without postexposure washings, were measured. The effects on zone width of placing the antiseptic-soaked blocks in tea were recorded. The MIC values of alexidine, cetyl pyridinium chloride and chlorhexidine gluconate, but not hexetidine, were all increased by adding polymethylmethacrylate to cultures. Tea added to the culture increased the MIC values against E. coli for alexidine, chlorhexidine and hexetidine, but not for cetyl pyridinium chloride. Zones of inhibition around antiseptic-treated blocks were reduced by washing and, in the case of hexetidine, completely abolished. Tea-soaking further reduced the zones of inhibition for alexidine and chlorhexidine, but not cetyl pyridinium chloride.(ABSTRACT TRUNCATED AT 250 WORDS)
