ESSENTIAL RESEARCH
Intra- and extra-oral halitosis: finding of a new form of extra-oral blood-borne halitosis caused by dimethyl sulphide.
Our study provides evidence that the VSC, CH(3)SH and to a lesser extent H(2)S are the main contributors to intra-oral halitosis and that CH(3)SCH(3) is the main contributor to extra-oral or blood-borne halitosis, due to a hitherto unknown metabolic disorder.

Effect of a Probiotic Water on Oral Health in Adults
Fort Wayne, United States
All genders
The purpose of this study is to evaluate the effects of consuming a probiotic on salivary, plaque, and tongue bacteria, as well as oral malodor (bad breath). Healthy volunteers will consume a probiotic powder, or a placebo powder, that is dissolved in water for 4 weeks.

ESSENTIAL RESEARCH
Identification of oral bacterial species associated with halitosis.
Subjects with halitosis harbor some bacterial species on their dorsal tongue surfaces that are distinct from bacterial species found in control subjects. This finding is consistent with the hypothesis that halitosis has a microbial etiology.

ESSENTIAL RESEARCH
Characteristics of 2000 patients who visited a halitosis clinic.
Even though it was observed that halitosis has a predominantly oral origin, a multidisciplinary approach remains necessary to identify ear, nose and throat or extra-oral pathologies and/or pseudo-halitosis/halitophobia.

Efficacy of Different Toothbrushes and Hygiene Regimen
Santos, Brazil
All genders
Phase 1/Phase 2
To evaluate: 1) Evaluate the efficacy of a regimen commercially available versus brush alone on established plaque and gingivitis on adolescents. The Group 1 will use the following procedure: Colgate Ultrasoft toothbrush, Colgate Total 12 toothpaste and Plax Mouthwash, and the other Group will use Colgate Ultrasoft toothbrush and Colgate Cavity Protection toothpaste; 2) The level of halitosis. Two calibrated and blinded examiners (Cohen Kappa 85%) will evaluate the gingival condition using the visible plaque indices, a simplified oral hygiene index - IHOS and gingival bleeding index, with the aid of a WHO probe. For the evaluation of halitosis levels, all individuals will respond to a questionnaire regarding personal data, general and oral health, which includes hygiene habits and received previous guidelines for the procedures to be performed in the second moment. At the next consultation, subjects will be assessed clinically for halitosis using the portable BreathAlert™ sulfide monitor (Tanita Corporation, Japan), in addition to the evaluation of the tongue flap index (ISL), pH and salivary flow. The evaluations will be in the following periods: baseline, 1, 3 and 6 months of brushing. Data will be submitted to descriptive statistical analysis to demonstrate the distributions frequency of biofilm indices and gingival bleeding. The differences in the criteria evaluated will be submitted to Fisher's exact test (α = 0.05) and their performance at different times will be evaluated by the Mann-Whitney test (α = 0.05).

ESSENTIAL RESEARCH
Tongue scraping for treating halitosis.
There is weak and unreliable evidence to show that there is a small but statistically significant difference in reduction of VSC levels when tongue scrapers or cleaners rather than toothbrushes are used to reduce halitosis in adults. We found no high level evidence comparing mechanical with other forms of tongue cleaning.

Effect of professional oral health care on the elderly living in nursing homes.
This study showed that POHC administered by dental hygienists to a group of elderly patients needing daily nursing care was associated with a reduction in prevalence of fever and fatal pneumonia.

ESSENTIAL RESEARCH
Comparative effects of different chlorhexidine mouth-rinse formulations on volatile sulphur compounds and salivary bacterial counts.
Important differences can be expected from different CHX formulations, in relation to both their anti-halitosis effect and anti-microbial activity in saliva. Formulations that combine CHX and CPC achieved the best results, and a formulation combining CHX with NaF resulted in the poorest.

Effect of Single Rinsing With Three Different Types of Mouthwash on VSC Levels in Morning Breath
L'aquila, Italy
All genders
Morning bad breath (MBB) is often an enduring upset; this double blind, crossover, randomized study aimed to evaluate the bad breath-suppressing of 3 commercially available mouth rinses (Mentadent Professional® 0.05%chlorhexidine (MPc), Meridol® Halitosis (MH) and CB12®) and a placebo on morning halitosis during a washout period of 1 week.

ESSENTIAL RESEARCH
Helicobacter pylori, gastrointestinal symptoms, and metabolic control in young type 1 diabetes mellitus patients.
H pylori infection and Cag-A-positive strains do not affect metabolic control in DM1 patients. With regard to gastrointestinal symptoms studied, H pylori infection, when present in participants with halitosis, seems to predict a worse metabolic control than in H pylori-negative patients with halitosis.
