Oral malodor

BACKGROUND: Halitosis in children implies psychosocial repercussions. Risk factors associated with this condition are unclear, and detection methods are inaccurate. AIM: To quantify the levels of sulfur-like compounds in children with asthma and healthy children from a novel validated assay, and to establish the risk factors related to halitosis. DESIGN: One hundred and twenty-eight individuals (63 healthy and 65 asthmatic) from 3 to 17 years of age were tested using a passive colorimetric sensor to measure the levels of sulfur-like compounds in breath and saliva...

The precise and reversible detection of hydrogen sulfide (H2 S) at high humidity condition, a malodorous and harmful volatile sulfur compound, is essential for the self-assessment of oral diseases, halitosis, and asthma. However, the selective and reversible detection of trace concentrations of H2 S (≈0.1 ppm) in high humidity conditions (exhaled breath) is challenging because of irreversible H2 S adsorption/desorption at the surface of chemiresistors. The study reports the synthesis of Fe-doped CuO hollow spheres as H2 S gas-sensing materials via spray pyrolysis...

BACKGROUND: We report on the case of a 21-year-old female who could not walk due to a huge Bartholin's cyst occupying the right vulvar region. The patient was treated by marsupialization of the Bartholin's cyst and postoperative antibiotic therapy. CASE SUMMARY: A 21-year-old female without a medical history of sexually transmitted diseases presented to our outpatient clinic with complaints of a painful vulvar lump and a green-yellowish discharge for 4 d. A large Bartholin's cyst, 10 cm in diameter, was suspected over the right side of the vulva...

The oral cavity is the second most microbially rich region of the human body, and many studies have shown that there is a strong association between microorganisms and oral health. Some pathogenic bacteria produce biofilms and harmful metabolites in the mouth that may cause oral problems such as oral malodor, periodontitis, and dental caries. Altering the oral microbiota by using probiotics may alleviate oral health problems. Thus, using multi-function screening, we aimed to identify probiotics that can significantly improve oral health...

Background and Objectives : The oral cavity is inhabited by pathogenic bacteria, whose growth can be inhibited by synthetic oral drugs, including antibiotics and other chemical compounds. Natural antimicrobial substances that elicit fewer negative side effects may serve as alternatives to synthetic agents for long-term use. Thus, the aim of this study was to evaluate the effects of edible mixed herbal extracts on the growth of oral pathogenic bacteria. Materials and Methods : The yield of each herbal extract was as follows: 5% Schizonepeta tenuifolia Briq (STB), 10...

MATERIALS AND METHODS: A comprehensive literature review was conducted on halitosis and its associated causes, including oral pathological factors, oral microbial influences, microbial metabolic pathways, gastrointestinal diseases, and gut microbiota dysbiosis...

Mal de Meleda (MDM) is a rare autosomal palmoplantar keratoderma (PPK) skin disorder (estimated incidence of 1 per 100,000 people) commonly associated with consanguinity and early childhood onset. MDM is characterized by bilateral diffusion of PPK plaques with delimited yellowish lesions that transgredien to the dorsum of the hands and feet. Additional features include nail dystrophy, lichenoid lesions, hyperhidrotic maceration, involvement of the knees and elbows, malodor, fungal superinfections, and digital constrictions...

OBJECTIVE: Halitosis or oral malodor is an unpleasant odor from the oral cavity. However, although patients with periodontitis often complain of halitosis, their relationship has not been fully elucidated. We reviewed previous literature based on the hypothesis that the relationship between halitosis and periodontitis is mediated by the oral microbiome. MATERIALS AND METHODS: This narrative review sought to provide insight into the causative role of the oral microbiome in influencing halitosis and periodontitis...

Individuals with dementia can present with varying challenges depending on their state of disease. The individuals caring for them may be faced with resistant behaviors when trying to provide adequate oral care. A poor oral condition can lead to decreased caloric and fluid intake causing multiple comorbidities to be exasperated due to the declining oral condition. Creating a management plan and an oral disease prevention plan are key to improving the overall health outcomes of these patients.

BACKGROUND: The gold standard method for diagnosing oral halitosis is the subjective organoleptic measurement. Device-supported methods are also widespread worldwide. The challenges and safety concerns around performing organoleptic measurements during pandemics and the diversity of measuring device alternatives raised our clinical question: which halitometer is the most suitable for diagnosing halitosis? METHODS: This systematic review was registered in PROSPERO (ID CRD42022320024)...

OBJECTIVE: There has been shown a relationship between "tongue coating" and "Simplified Oral Health Index, periodontal status, modified mallampati classification (MMC) of the oropharynx and oral malodor". The purpose of this study is to assess the frequency of tongue coating and relative factors (sex, age, smoking, systemic disease and oral health indices) among patients referred to Dental School of Kerman University. METHODS: In this cross sectional study 250 patients referred to dental school of Kerman university of medical sciences were examined...

BACKGROUND: Oral malodor is a major periodontal complaint, but the best method for assessing the halitosis grade is still undefined. The primary objective of the study was to detect the halitosis grade in the exhaled breath using the three distinct techniques and to compare the readings with different clinical indices to find out the best method of halitosis grading. MATERIALS AND METHODS: A total of 90 patients with chronic periodontitis having oral malodor were included in the study...

INTRODUCTION: Few studies have examined the effect of feedback based on oral-malodor measurements on the motivation to quit smoking. Therefore, this study examined whether oral-malodor measurements were associated with the intention to quit smoking. METHODS: This retrospective, uncontrolled before-after study invited smokers to a workplace health event in 2019 and 2020 to motivate them to quit smoking. They attended seminars on oral health and smoking cessation aids, and then underwent respiratory function and oral-malodor measurements using exhaled and oral cavity air, respectively...
