Oral Malodorous Compound Inhibits Osteoblast Proliferation

Journal of Periodontology, 2009
Background: Oral malodorous compounds including hydrogen sulfide (H2S) are causative agents of periodontitis because the toxicities are similar to that of cyanate. Previous studies demonstrated that volatile sulfur compounds (VSCs) were highly toxic to periodontal tissues, causing a large reduction in the amount of collagen in human gingival ...

Evaluation of oral malodor in children

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2008
The aim of this study was to assess oral malodor in highly caries-active children aged 7-15 years, analyze its association with oral malodor parameters, and investigate whether oral hygiene practices and orodental treatments can decrease the effect of oral malodor.The study included a total of 30 subjects with high caries activity (11 boys and 19 girls)

Oral Malodor Management

2011
The key to a successful resolution of a breath odor complaint is a correct diagnosis of its source (for more details see Chap. 9). Once the objectivity of the complaint has been substantiated and the source of the malodor located, an appropriate treatment may be implemented.

The Complaint of Oral Malodor

Psychosomatic Medicine, 1996
Oral malodor (halitosis) is a common concern in Western society. As with other human perceptions, emotional as well as cognitive variables play a major role in one's sensation and complaint. To study factors potentially associated with the complaint of oral malodor, periodontal and psychological evaluations were carried out on 38 subjects (66% female ...

Non‐Oral Etiologies of Oral Malodor and Altered Chemosensation

Journal of Periodontology, 1992
A number of non‐oral causes for oral malodor have been discussed. Several well documented etiologies for non‐oral malodor include renal failure, cirrhosis of the liver, and diabetes mellitus. Each of these conditions has been examined using analytical instrumentation. In addition there appear to be several other metabolic conditions involving enzymatic

Reduction of malodor by oral cleansing procedures

Oral Surgery, Oral Medicine, Oral Pathology, 1976
Organoleptic and gas chromatographic methods were employed to establish the threshold of odor objectionability of methylmercaptan and hydrogen sulfide and to assess the relative effectiveness of different oral hygiene measures to reduce the malodor to acceptable levels. The study showed that methylmercaptan and hydrogen sulfide concentrations below 0.5

Effect of fixed appliances on oral malodor

American Journal of Orthodontics and Dentofacial Orthopedics, 2011
The objective of this study was to evaluate the effect of fixed appliances on oral malodor.Forty-one patients participated in this study. They were randomized into 2 groups: treated with fixed orthodontic appliances and untreated controls. Oral malodor measurements and the gingival and plaque indexes were recorded in each group by same periodontist ...

Reduction of Oral Malodor by Oxidizing Lozenges

Journal of Periodontology, 1997
The main purpose of the study was to examine the anti‐malodor properties of oxidizing lozenges, as compared to breath mints and chewing gum. Healthy, young adult volunteers (N = 123; mean age 24.5 years) were measured for oral malodorrelated parameters (whole mouth odor measured by 2 judges; tongue dorsum posterior odor using the spoon test; volatile ...

In vitro models for oral malodor

Oral Diseases, 2005
A model is a representation of some real phenomena and contains aspects or elements of the real system to be modeled. The model reflects (or duplicates) the type of behavior (or mechanisms) seen in the real system. The main characteristic of any model is the mapping of elements or parameters found in the system being studied (e.g. tongue dorsum biofilm

Correlation between oral malodor and periodontal bacteria

Microbes and Infection, 2002
Volatile sulfur compounds (VSCs), including hydrogen sulfide, methyl mercaptan, and dimethyl sulfide, are primarily responsible for oral malodor. Recently, the mgl gene encoding L-methionine-alpha-deamino-gamma-mercaptomethane-lyase, which produces methyl mercaptan, was cloned from Porphyromonas gingivalis.
