Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Malodor is a multifactorial condition with oral pathology representing the main culprit and the tongue being the first to second contributor to the malodor. Bacterial load can represent a quantifiable measure regardless of the original pathology. It is hypothesized that reduction in malodor can be represented by tongue changes both in appearance, bacterial and biofilm load reduction (measured by CFU and volatile gases measurement), organoleptic measurement and subjective improvement. Methods: A randomized controlled prospective study under IRB approval. Diagnostic criteria for enrollment and follow up were organoleptic test by 2 judges, halimeter reading, tongue colores changes HALT questionnaire and direct aerobic and anaerobic tongue cultures measured by CFU. Patients were treated with laser tongue debridement (LTD) with an Er,Cr:YSGG solid state laser has been shown to be effective in biofilm reduction.
