Detailed Description:

Failure to perform oral hygiene adequately at the gingival margin results in the formation of a pathogenic plaque that has the potential to initiate gingivitis and in some individuals to progress to periodontitis. However, factors, such as dexterity and motivation, can limit the effectiveness of daily self-performed oral hygiene. The use of a chemical plaque-inhibitory mouthrinse as an adjunct to toothbrushing may improve the oral health of individuals who are inadequate in mechanical plaque control in maintaining gingival health.

Chlorhexidine (CHX) has been effectively used in the treatment of gingival inflammation and can be considered as the gold standard for oral antiseptics.

The effectiveness of CHX in reducing the formation of dental plaque and preventing gingivitis in addition to professional mechanical debridement were studied in several clinical studies, but there is limited number of studies investigating the effects of CHX on untreated gingivitis and subgingival microbiota.


Ages Eligible for Study:   18 Years to 45 Years   (Adult)
