Treatment of Halitosis With Photodynamic Therapy in Older Patients

Halitosis

Halitosis is the term used to define an unpleasant odor emanating from the mouth. Some lung diseases, such as bronchiectasis, are among the extra-oral causes of this condition. However, no studies have evaluated the causes and treatment of halitosis in the population of older adults with bronchiectasis. Methods and analysis: A randomized, controlled trial is proposed. The patients will be divided into four groups: G1- healthy older adults with 10 teeth or more (n = 40); G2- healthy older adults who wear complete dentures (n = 40); G3- older adults with bronchiectasis and 10 teeth or more (n = 40); and G4- older adults with bronchiectasis who wear complete dentures (n = 40). Halitosis will be evaluated based on the measurement of volatile sulfur compounds using gas chromatography. The participants with halitosis will be randomized into two subgroups: treatment with photodynamic therapy (n = 20) or cleaning of the tongue with a tongue scraper (n = 20). After the treatments, a second evaluation will be performed, along with a microbiological analysis (qPCR) for the identification of the bacteria P. gingivalis and T. denticola. If the halitosis persists, the dentate participants will received periodontal treatment and the edentulous participants will be submitted to hygiene procedures for the mucosa and dentures. The evaluation of halitosis and the microbiological analysis will be repeated. If the halitosis is resolved, the participants will return after three months for an additional evaluation. This protocol will determine the effectiveness of phototherapy regarding the reduction of halitosis in healthy older adults and those with bronchiectasis.

Effect of Miswak and Miswak Extract on Oral Malodor

Oral MalodorHalitosis

The aim of this experiment is to investigate the effect of Miswak on oral malodor and to determine whether this effect -if present- is the result of the mechanical action of Miswak or the chemical effect of its extract

Laser Tongue Debridement for Oral Malodor

Halitosis

Malodor is a multifactorial condition with oral pathology representing the main culprit and the tongue being the first to second contributor to the malodor. Bacterial load can represent a quantifiable measure regardless of the original pathology. It is hypothesized that reduction in malodor can be represented by tongue changes both in appearance, bacterial and biofilm load reduction (measured by CFU and volatile gases measurement), organoleptic measurement and subjective improvement. Methods: A randomized controlled prospective study under IRB approval. Diagnostic criteria for enrollment and follow up were organoleptic test by 2 judges, halimeter reading, tongue colores changes HALT questionnaire and direct aerobic and anaerobic tongue cultures measured by CFU. Patients were treated with laser tongue debridement (LTD) with an Er,Cr:YSGG solid state laser has been shown to be effective in biofilm reduction.

Halitosis Devised Questionnaire Evaluating a New Treatment

Halitosis

The investigators propose a novel assessment of oral malodor (halitosis) by a quality of life (QOL) questionnaire designed specifically for halitosis and a new treatment for halitosis by improvement of mouth dryness.

Questionnaire Regarding the Effect of Wearing Face Masks on Oral Health

Dry MouthHalitosis

During the current COVID-19 pandemic, the use of face masks is recommended / mandatory to prevent infection. Patients and students have reported to experience limitations in their oral health-related quality of life, especially with regard to the occurrence of dry mouth and halitosis, while wearing face masks. Scientific studies regarding the effects of face masks have so far focused exclusively on medical staff. Studies among the general population are not yet available, but are of interest as dry mouth is a risk factor for dental diseases (e.g., caries, erosion). Therefore, the present study aims at performing a questionnaire survey regarding self-perceived dry mouth and halitosis and the use of face masks (type, wearing time).

Impact of Bracket Design and Oral Hygiene Maintenance on Halitosis in the Orthodontic Patient

HalitosisOral Hygiene

The advantage of self-ligating brackets on periodontal health has yet to be determined. In addition, the utilization of tongue scraping as an adjunct to traditional oral hygiene measures has yet to be studied in orthodontic patients. The aim of this study is to evaluate the effect of bracket type on plaque accumulation and also the impact of the appliance on oral malodor. In addition, the effect of tongue scraping on halitosis will be studied in patients undergoing orthodontic treatment. We hypothesize that self-ligating brackets will harbor less plaque than normal brackets, that tongue scraping will significantly decrease halitosis in patients undergoing orthodontic treatment and that patients with self-ligating brackets will exhibit less halitosis as measured by halimeter.

Chios Mastic Mouthwash and Halitosis and Oral Hygiene in Orthodontic Patients

HalitosisOrthodontic Appliance Complication

Halitosis is the third most common oral condition perceived by the patients as pathologic, after caries and periodontal diseases. Although it is difficult to estimate the prevalence of halitosis in the population due to the different assessment methods, the available descriptive epidemiologic studies estimate that 30-50% of the population experience oral malodor. Pathologic halitosis most commonly (85%) originates from the oral cavity and is a result of bacterial deposits that cover the tongue or are found in the inflamed oral mucosa, under poor-quality restorations, orthodontic mechanisms, carious lesions or mucosal ulcers. Odor usually results from the microbial degradation of organic substrates present in saliva. This interaction generates malodorous volatile sulfur compounds (VSCs), of which the three most common are: hydrogen sulfide (H2S), methyl-mercaptan (CH3SH) and dimethyl sulfide [(CH3)2S]. Orthodontic patients with fixed appliances are more prone to halitosis, due to the increased plaque accumulation and the increased amounts of available nutrients for the supragingival and subgingival microbes .
