[Halitosis--foetor ex ore].

BACKGROUND: An overview is presented on the etiology, diagnosis, and therapy of halitosis. METHODS: Results are given of our multidisciplinary halitosis outpatient department started in 1994. The team consists of ENT specialists and paradontologists, occasionally assisted by a psychiatrist. The oral odor is confirmed with a halitometer (Interscan Corporation, Model RH-17E USA). 491 Patients, nearly the same number of males as females, mostly between 20 and 50 years of age were seen. RESULTS: Oral causes (87%) were due to tongue coating (51%), gingivitis (17%), paradontitis (15%), or combinations of factors (17%). The other 13% involved causes related to ENT problems (4%), both ENT and oral (3%), digestive tract (1%), and presumed psychiatric pathology (5%). CONCLUSIONS: Many patients underwent diagnostic and therapeutic aimed interventions to no avail prior to their arrival in our halitosis clinic. Usually advising the patient to maintain better oral hygiene is sufficient.

An inventory of patients' response to treatment at a multidisciplinary breath odor clinic.

OBJECTIVE: This study was undertaken to assess patients' response to their treatment at a multidisciplinary oral malodor clinic. METHOD AND MATERIALS: In 4 years, a multidisciplinary breath odor clinic in Belgium examined 406 patients. The team consisted of an ear, nose, and throat specialist, a periodontologist, occasionally a specialist in internal medicine, and, more recently, a psychiatrist. After the initial visit, each patient was scheduled for a follow-up appointment 2 to 6 months later; however, only 143 patients (35%) showed up for this control visit. The remaining 65% of the patients answered a mailed questionnaire. RESULTS: About half of the patients who returned no longer had complaints, while 17% reported no improvement. This group was characterized by imaginary bad breath and manifest psychologic problems. There was also disbelief of their cure, although clinical examination (organoleptic evaluation and volatile sulfide measurement by means of a portable monitor) did not reveal any oral malodor. Some also insufficiently performed the recommended oral hygiene measures (tongue brushing and interdental cleaning). Most of the patients who returned the questionnaire were disappointed by the suggestion that their halitosis was the result of insufficient oral hygiene. CONCLUSION: Better education of both the public and dental professionals as to the most frequent cause of halitosis, insufficient oral hygiene, might elevate the level of compliance by patients.

[The sampling of plaque specimens in oral microbiology].

Sampling is the first and most important step in the bacterial analysis of periodontal or endodontal infections. Sterile paperpoints are the ultimate tool to perform the sampling. Sampling is preferably done under continuous CO2-flushing, to preserve an anaerobic environment for the bacteria. For the dilution and the transport of the bacteria, Reduced Transport Fluid (RTF) is the most reliable fluid, when culturing is indicated. In all other cases, sterile physiologic water is sufficient.

[Halitosis, foetor ex ore].

OBJECTIVE: To review the results of a multidisciplinary approach on halitosis. DESIGN: Descriptive. SETTING: University Hospital Leuven, Belgium. METHODS: Review of the data on etiology, diagnosis and therapy of halitosis, obtained by a multidisciplinary team consisting of ENT specialists, periodontologists and a psychiatrist. Malodour was confirmed by a halimeter. RESULTS: 491 patients, equally males and females, with a concentration between 20-50 years of age were seen. Oral causes (87%) were due to tongue coating (51%), gingivitis (17%), periodontitis (15%) or combinations 17%). The other 13% causes were due to ENT-related problems (4%), both ENT and oral (3%), digestive tract (1%) and presumed psychic (5%). CONCLUSION: Halitosis is a rather unknown medical problem that often can be solved by a multidisciplinary approach.
