Just to refresh everyone’s memory here are the 5 types of malodor from the Clasification of Malodor thread:
According to me (1) , there are 5 types of malodor:
Type-1 halitosis takes origin from tongue dorsum. Foods are turned aromatic-volatil compounds by anaerobic bacteria between papillae.
Type-2 halitosis takes origin around oral cavity. Paranasal sinuses, Waldeyer's lymphoid ring, retronasal mucosa, oropharynx etc.
Type-3 halitosis takes origin from gastrointestinal canal. Reflux, H. pylori gastritis, bacterial over growth, malabsorptions, gut and colon diseases.
Type-4 halitosis takes origin from blood gases. Many catabolic substances leave the body via renal or hepatic ways. If liver and/or kidneys can not truely filter them, this catabolic waste may resolve in blood plasm and enter to systemic blood circulation. Lungs try to filter and exhale them via breath. They may have a bad odor. This causes bad breath.
Type-5 halitosis is psychologic.
