Summary

The aim of the proposed controlled clinical trial is to evaluate the effect of photodynamic therapy (PDT) on the formation of volatile sulfur compounds (VSCs) from coated tongue and its action on the severity of halitosis in adolescents using different treatment protocols.

HYPOTHESIS

1. \- Null hypothesis: There is no change in halitosis following the use of photodynamic therapy.
2. \- Experimental hypothesis: There is a reduction in halitosis following the use of photodynamic therapy alone or in combination with a tongue scraper.

Conditions

  • Halitosis

Interventions

OTHER

PDT

A single session of PDT will be performed with the Chimiolux® photosensitizer at a concentration of 0.005% applied over the middle and posterior thirds of the dorsum of the tongue. Nine points will be irradiated, the device will be previously calibrated with a wavelength of 660 nm, power of 100 mW, energy of 9 joules for 90 seconds per point in Groups 2 and 4 and 12 joules for 120 second per point in Groups 3 and 5

OTHER

Tongue Scraper

The pacient will scrap the tongue 10 times.
