Halitosis*

OBJECTIVETo establish a salivary sediment malodor system, and to evaluate the effect of several kinds of bacteria dedicated to the halitosis formation, hence to identify halitosis-correlated bacteria.

METHODSThe proportion of the supernatant and sediment, gained from centrifugal whole saliva, was adjusted to establish a salivary sediment malodor system incubated in facultative aerobic environment under 37 degrees C for 7 hours. The halitosis indexes in both gaseous phase and liquid phase were checked by direct sniffing, and volatile sulphur compounds (VSCs) and pH were determined by halimeter and glass electrode respectively between hours to evaluate the malodor formation. The suspended fluid of suspicious halitosis-correlated bacteria and non-halitosis-correlated bacteria and water control were introduced into the salivary sediment system incubated for 1 hour. The five groups were incubated in facultative aerobic environment under 37 degrees C in the residual hours. The halitosis indexes, VSCs and pH changes were recorded between hours.

RESULTSThe salivary sediment malodor system can simulate the metabolism of halitosis formation to produce halitosis. The odors of the suspicious halitosis-correlated bacteria introduced groups were higher than the non-halitosis-correlated bacteria and water control group.

CONCLUSIONWith its simple but fundamental manipulations, incubated whole saliva is a powerful model for study of the metabolism of the oral mixed microbial flora, malodor formation, and other oral diseases-related processes.

Halitosis, bad breath or oral malodour are all synonyms for the same pathology. Halitosis has a large social and economic impact. For the majority of patients suffering from bad breath, it causes embarrassment and affects their social communication and life. Moreover,halitosis can be indicative of underlying diseases. Only a limited number of scientific publications were presented in this field until 1995. Ever since, a large amount of research is published, often with lack of evidence. In general, intraoral conditions, like insufficient dental hygiene, periodontitis or tongue coating are considered to be the most important cause (85%) for halitosis. Therefore, dentists and periodontologists are the first-line professionals to be confronted with this problem. They should be well aware of the origin, the detection and especially of the treatment of this pathology. In addition, ear-nose-throat-associated (10%) or gastrointestinal/endocrinological (5%) disorders may contribute to the problem. In the case of halitophobia, psychiatrical or psychological problems may be present. Bad breath needs a multidisciplinary team approach: dentists, periodontologists, specialists in family medicine, ear-nose-throat surgeons, internal medicine and psychiatry need to be updated in this field, which still is surrounded by a large taboo.Multidisciplinary bad breath clinics offer the best environment to examine and treat this pathology that affects around 25% of the whole population. This article describes the origin, detection and treatment of halitosis, regarded from the different etiological origins.

OBJECTIVETo study the anti-halitosis effect of sugar-free chewing gum through their influence on odor induced by cysteine.

METHODSTen volunteers were randomly divided into the treatment group and the untreated group; each group consisted of five volunteers. All volunteers consented to participate in a test in which breath odor was induced by cysteine. After the test, the treatment group chewed sugar-free chewing gum for 1 min, whereas the untreated group did not undergo any treatment. The effectiveness was determined by the percent reduction of H2S, CH3SH, and (CH3)2S response after the volunteers chewed gum for 1, 10, and 20 min.

RESULTSAt 1, 10, and 20 min, H2S of the treatment group was reduced by 82.68%, 92.27%, 97.47%, respectively, CH3SH was reduced by 65.49%, 73.79%, and 82.89%, respectively, and (CH3)2S was reduced by 60.45%, 73.82%, and 59.72%, respectively. The differences between the two groups at different times were significant (P < 0.05).

CONCLUSIONChewing gum can effectively inhibit cysteine-induced odor.

Psychosomatic disorders are defined as disorders characterized by physiological changes that originate partially from emotional factors. This article aims to discuss the psychosomatic disorders of the oral cavity with a revised working type classification. The author has added one more subset to the existing classification, i.e., disorders caused by altered perception of dentofacial form and function, which include body dysmorphic disorder. The author has also inserted delusional halitosis under the miscellaneous disorders classification of psychosomatic disorders and revised the already existing classification proposed for the psychosomatic disorders pertaining to dental practice. After the inclusion of the subset (disorders caused by altered perception of dentofacial form and function), the terminology "psychosomatic disorders of the oral cavity" is modified to "psychosomatic disorders pertaining to dental practice".

We selected a patient with physiological bad breath from among the outpatients with bad breath that have visited the halitosis control clinic in KUMC. We identified the factors that were associated with the development of bad breath and assessed the occurrence of discomfort in the mouth; thereafter, we were able to prescribe a treatment method for the patient. We determined the daily routine of the patient through a questionnaire and a diary of dietary life. From these analyses, we deduced the factors associated with her physiologic halitosis. We combined this information with the results of analysis of her oral and exhaled gas measurements, nasal gas measurements by oral malodor measuring devices, and salivary measurements to develop a treatment method that we prescribed to the patient. We conclude that oral health education, including correction of the patient's mismanaged oral-care methods and routines, could act as an alternative treatment method for patients with physiologic halitosis in Korea.

OBJECTIVE: To present a case of subglottic foreign body (FB) impaction in a 50-year-old woman diagnosed with bronchial asthma for 15 years.
METHODS:
Design: Case Report
Setting: Tertiary Public Hospital
Patient: One
RESULTS: A 50-year-old woman with recurrent cough and dyspnea for 15 years that had been managed as a bronchial asthma developed stridor and halitosis in the last 5 years. Flexible laryngoscopy revealed a subglottic mass and CT scan confirmed a suspicious foreign body in the lumen of the subglottis. Signs and symptoms resolved after peroral endoscopic removal of the foreign body from the larynx. Histopathology of the extracted material from the airway confirmed it to be "bone tissue".
CONCLUSION: Foreign body aspiration can occur in adults without predisposing factors. Its diagnosis can be challenging as it can mimic respiratory disorders such as bronchial asthma. Endoscopy and computed tomography are valuable for correct diagnosis and management. An incorrect initial diagnosis should be considered in the light of unresolved symptoms and prompt referral to an appropriate specialist may prevent undue suffering and dangerous complications. 

BACKGROUND: The purpose of this study was to determine the degree of oral care, perceived halitosis, halitosis, interpersonal relationships and oral health-related quality of life and to examine the relationships among these variables.METHODS: The participants were 94 elderly people. The questionnaire included questions on oral care, perceived halitosis, interpersonal relationships, and oral health-related quality of life. Halitosis was measured using odor breath tester.RESULTS: A total of 63.8% of the elderly did not receive regular oral care. The halitosis score was 1.59, thus indicating moderate halitosis. The current perceived halitosis figure was 1.54, participants responded that they feel slight. There was no significant correlation between halitosis and perceived halitosis. Furthermore, there was no significant difference in halitosis and perceived halitosis according to the oral care. Perceived halitosis was negatively correlated with oral health-related quality of life. Interpersonal relationships were correlated with oral health-related quality of life.CONCLUSIONS: It is necessary to actively promote the need for oral care among the elderly. Moreover, older people need regular oral care to prevent halitosis and improve their oral health-related quality of life.

OBJECTIVETo assess the relationship between oral malodor, volatile sulphur compounds (VSCs) levels in the mouth air and periodontal index; the role of tongue in the production of VSCs and halitosis.

METHODS60 periodontitis patients with oral malodor were included. Oral malodor was estimated by organoleptic method (organoleptic rating, OR); VSCs level measurements before and after cleaning the tongue coating were made with a portable sulphide monitor (halimeter), respectively; periodontal probing depth (PD) and the proportion of PD >/= 4 mm sites, bleeding index (BI) and plaque index (PLI) were examined; tongue coating was estimated with thickness (Tt) and area (Ta) on the dorsal surface of tongue.

RESULTSThe correlation was analyzed with Spearman method. There was a significantly positive correlation between OR, VSCs levels and BI, PLI, and Tt, respectively (P < 0.01). OR and VSCs levels was also related with Ta (P < 0.05). There was a weakly correlation between VSCs levels and PD, and the proportion of PD >/= 4 mm sites (r = 0.26, P < 0.05). No correlation between OR and PD, and the proportion of PD >/= 4 mm sites was existed. Reduction of VSCs levels after cleaning tongue coating was statistically significant (t = 10.15, P < 0.01), and also significantly related with thickness and area of tongue coating (P < 0.01).

CONCLUSIONSIn present study, OR and VSCs levels were significantly correlated with gingival inflammation (BI), condition of oral hygiene (PLI), and tongue coating. The relationship between OR, VSCs levels and periodontal probing depth was not found obviously. VSCs levels were significantly reduced after cleaning tongue coating, but the percentage of reduction was less than that of the previous studies.
