The Additional Effect of Tongue Scraping on Halitosis Parameters in Initial Periodontal Therapy
The Additional Effect of Including Tongue Scraping to the Oral Hygiene Instructions on Halitosis Parameters in Periodontitis Patients Undergoing Standard Initial Periodontal Therapy
Periodontitis can lead to tooth loss which may impair chewing ability and aesthetics. In addition, periodontitis can give rise to halitosis.
Standard initial periodontal treatment consists of supra and subgingival biofilm reduction and removal of calculus. Recently, the European Federation of Periodontology introduced clinical practice guidelines for the treatment of periodontitis. The use of a tongue scraper is not mentioned as element in the standard initial treatment of periodontitis.
We have planned a clinical study in order to provide information about the effect of standard initial periodontal therapy and the additional effect of the use of a tongue scraper as part of the oral hygiene instructions on halitosis parameters in periodontitis patients.
