Aim: To report the data from a multidisciplinary bad breath consultation in Germany.
Materials And Methods: In this cross sectional study, 407 patients attending a bad breath consultation were examined by a specially trained dentist, with an ENT-specialist, an internist, and a psychologist on call.
Results: All patients reported suffering from bad breath but only 72.1% showed detectable signs of breath malodour. Within this group, 92.7% revealed an oral cause, 7.3% revealed an extra-oral cause. Within the group without malodour, 76.3% had received prior diagnostics and treatments from other doctors, whereby 36% had received one or more gastroscopies and 14% had undergone an ENT operation. In only ten cases had an organoleptic evaluation of the putative malodour been performed.
Conclusion: Our data reveal that breath malodour is mainly of oral origin and that patients with pseudo-halitosis are frequently not diagnosed correctly by doctors, resulting in a considerable amount of over-treatment.

Background: Many people suffer from body and breath malodour syndromes. One of these is trimethylaminuria, a condition characterized by excretion in breath and bodily fluids of trimethylamine, a volatile and odorous chemical that has the smell of rotting fish. Trimethylaminuria can be primary, due to mutations in the gene encoding flavin-containing monooxygenase 3, or secondary, due to various causes.

Halitosis is a socially avoided topic with an increasing worldwide prevalence. This study aimed to investigate the correlation between the different forms of halitosis and factors such as: gender, smoking, stress, and oral hygiene. We analysed data from patients registered at the Center of Salivary Diagnostics, Hyposalivation and Halitosis at the University Center for Dental Medicine Basel over a 17-year period, using both subjective and objective approaches to determine the presence of halitosis.

Objective: Morning breath is a temporary and unpleasant malodour sourced from the mouth, which occurs upon awakening. This double-blind, crossover, randomized clinical trial aimed to evaluate the bad-breath suppression of three commercially available mouthwashes: Mentadent Professional® Chlorhexidine 0.05% with vitamin C (ChxC), Meridol Alito Sicuro® (SnF ) and CB12® (ZnChx) compared to a placebo (PbO) on morning halitosis.

Aim: To evaluate the additional effect of a single session of antimicrobial photodynamic therapy (aPDT) on the tongue as an adjunct to scaling and root planing (SRP) on most common volatile sulfur-producing microbes such as Porphyromonas gingivalis (Pg), Treponema denticola (Td) and Fusobacterium nucleatum (Fn) on 3rd, 7th and 14th day postoperatively using RT-PCR analysis.
Method And Materials: Twenty-four patients of either sex, presented with moderate to severe malodor, detected by a portable breath checker (Tanita®) were considered for the study and assigned to group A & B. Scaling and root planning was performed in both the groups, followed by photodynamic therapy on the tongue surface in group A.
