Summary

The Bacterial N-Acetylated Alpha-Galactosaminidase (BANA) test shows a significant association with subjective oral malodor assessments, independent of volatile sulfide measurements. This suggests BANA testing can complement sulfide monitoring for a comprehensive oral malodor evaluation.

Area of Science:

  • Dentistry
  • Oral Health
  • Biochemistry

Background:

  • Oral malodor (halitosis) affects a significant portion of the adult population.
  • Current diagnostic methods include volatile sulfide measurements and organoleptic assessments.
  • The role of specific bacterial enzymes, like BANA, in contributing to malodor requires further investigation.

Purpose of the Study:

  • To evaluate the association between the Bacterial N-Acetylated Alpha-Galactosaminidase (BANA) test and various oral malodor parameters.
  • To determine if BANA test results correlate with both instrumental (sulfide monitor) and subjective (organoleptic) malodor measurements.
  • To explore the BANA test's utility as a diagnostic tool for oral malodor.

Main Methods:

  • A study involving 52 Israeli adults, with 43 self-reporting oral malodor.

  • Oral malodor was assessed using a portable sulfide monitor and organoleptic ratings (whole mouth, tongue, saliva).
  • BANA test samples were collected from four sites (pocket, tongue, saliva) and scored.

    • Main Results:

    • BANA scores demonstrated a significant association with organoleptic odor ratings, particularly for saliva (r = 0.500; p < 0.001).
    • BANA test results from different sites were not significantly correlated with sulfide monitor readings.
    • Multiple regression analysis indicated that both BANA scores and sulfide levels significantly contributed to predicting organoleptic malodor measurements.

    Conclusions:

    • The BANA test is associated with a component of oral malodor that is distinct from volatile sulfides.
    • BANA testing may serve as a valuable adjunct to volatile sulfide measurements for a more complete assessment of oral malodor.
    • Further research can explore the clinical application of BANA testing in managing halitosis.
