The use of a tongue scraper is not mentioned as element in the standard initial treatment of periodontitis.\n\nThe investigators 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.",[79,80,81],"Periodontitis","Halitosis","Tongue Condition",[83,84,85,86,87,88],"periodontitis","halitosis","oral malodor","tongue coating","tongue cleaning","non-surgical treatment","2026-02-10",{"date":91,"type":92},"2026-02-13","ACTUAL",{"date":94,"type":92},"2024-09-01",{"date":96,"type":73},"2026-12-01",{"name":5,"class":6},1]
