Background: The organoleptic evaluation is considered the gold standard between evaluation methods of halitosis, but its main drawback is the difficulty of reproducibility. Purpose: The aim of this study was to evaluate the reproducibility of an organoleptic evaluation method using three levels of scores (0 = no odor, 1 = moderate odor, and 2 = strong odor) to increase reliability between researchers and clinicians. Methods: The evaluation was blindly conducted by two examiners previously calibrated by the Smell Identification Test and compliance in clinical trials. Statistical calculations were done with STATA ® software version 9.0. Results: The degree of agreement between examiners was 82.5%, with estimated Kappa (κ =0.69), with substantial agreement.   Conclusion: The scale used in this study by organoleptic method was effective and reproducible but must be repeated and compared to other methods for better consistency of results.
