 Halitosis refers to the condition of malodor of the oral cavity 2009. Halitosis is estimated to affect 50 of the population with varying degrees of intensity and etiology Meskin 1996. In 80 of all cases halitosis is secondary to underlying oral conditions Miyazaki, Sakao et al. 1995.The etiology of halitosis is often caused by food debris and biofilm buildup on the teeth and tongue, deep periodontal pockets, severe carious lesions and poor dental restorations Yaegaki and Sanada 1992; Morita and Wang 2001; Morita and Wang 2001. The odor emanating from the oral cavity is produced by microbial putrefaction of residual oral debris, resulting in production of malodorous Volatile Sulfur Compounds VSCs Porter and Scully 2006. Previous studies have shown that the amount of VSCs in breath increases with the number, depth, and bleeding tendency of the periodontal pockets Quirynen, Zhao et al. 2002. Therefore plaque control, which directly impacts periodontal health, is an important factor in the control of halitosis.
