Abstract
|
|
|
Objectives: The authors surveyed the amounts of tongue plaque, salivary flow, and dental plaque which are local
factor that occurs oral malodor, but generally effects the odor relatively.
Methods: With 40 participants of adult male for reference of oral malodor regulation, author used Oralchroma and BB checker to measure the oral malodor and had oral examination, salivary test, dental plaque examination, and PFRI.
Results: Correlation coefficient between tongue plaque and hydrogen sulfide is r=0.360(p=0.023). Correlation coefficient between PFRI and hydrogen sulfide is r=0.312 (p=0.050). The hydrogen sulfide average value in higher level group of PFRI is 60.0 and value in lower level group of PFRI is 20.4. So higher PFRI level group is higher hydrogen sulfide value than lower PFRI level group in statistically(p<0.01).
Conclusion: In the oral malodor control which it occurs by the factors in the oral cavity, control of tongue plaque and control of dental plaque have to be done. Also, prescription for chemical plaque control for lowering the plaque formation rate may be needed to control the oral malodor.
