Abstract Background The high risk of cross-infection during tracheal intubation has caused excessive occupational anxiety for anaesthesiologists amid the novel coronavirus disease 2019 (COVID-19) pandemic. Currently, there is no effective way to attenuate their anxiety in clinical practice. We found that anaesthesiologist with better protective equipment might experience decreased levels of anxiety during intubation. Methods In this study, 60 patients who underwent intubation and extubation in the operating room were enrolled, and then randomized 1:1 to either wear protective sleeves (protective sleeve group) or not (control group). Visual analogue scale (VAS) was used to measure the anxiety level of anaesthesiologists during intubation. The respiratory droplets of patients on the sleeve, and the anaesthesiologists’ perception including the patient’s oral malodour, exertion, satisfaction degree, waist discomfort and shoulder discomfort were recorded. The patients’ anxiety, oppressed feelings and hypoxia and postoperative complications were all measured and recorded. Results Compared with the control group, the anaesthesiologists in protective sleeve group achieved lower anxiety scores and better satisfaction degrees during the process of intubation and extubation (all P < 0.05). Respiratory droplets were observed only on the inner side, but not the external side, of the protective sleeves (P < 0.001). The incidence of the anaesthesiologists’ perception of patients’ oral malodour was significantly lower in the protective sleeve group (P = 0.02) and no patients developed hypoxemia or intubation-related complications in the protective sleeve group. Conclusion Using protective devices for intubation might eliminate droplet transmission from patients to anaesthesiologists, while also decreasing their anxiety in a controlled operating room environment.

Background and Objective: Oral malodour is often observed in gingivitis and chronic periodontitis patients, and the tongue microbiota is thought to play a major role in malodorous gas production, including Volatile Sulfur Compounds (VSCs) such as hydrogen sulfide (H2S) and methanethiol (CH3SH). This study aimed to examine the link between the presence of VSCs in mouth air (as a marker of oral malodour) and the oral bacterial ecology in the tongue and periodontal niches of healthy, gingivitis and periodontitis patients. Methods: Participants were clinically assessed using plaque index, bleeding on probing (BOP) and periodontal probing depths, and VSC concentrations in their oral cavity measured using a portable gas chromatograph. Tongue scrapings, subgingival and interdental plaque were collected from healthy individuals (n=22), and those with gingivitis (n=14) or chronic periodontitis (n=15). The bacterial 16S rRNA gene region V3-V4 in these samples was sequenced and the sequences analysed using the Minimum Entropy Decomposition pipeline. Results: Elevated VSC concentrations and CH3SH:H2S were observed in periodontitis compared to health. Significant ecological shifts were observed in the tongue microbiota of healthy subjects who had higher plaque scores, suggesting a possible connection between the microbiota of the tongue and the periodontium and that key dysbiotic changes may be initiated in the clinically healthy who have higher dental plaque accumulation. Greater subgingival bacterial diversity was positively associated with H2S in mouth air. Periodontopathic bacteria known to be prolific VSC producers increased in abundance on the tongue and this was associated with increased bleeding on probing (BOP) and a greater % of periodontal pockets >6mm, supporting the suggestion that the tongue may become a reservoir for periodontopathogens. Conclusion: This study highlights the importance of the periodontal microbiota in malodour and has detected dysbiotic changes in the tongue microbiota in periodontitis.

Objectives: To describe the patients' perception of their own breath and verify that halitosis can lead to loss of quality of life of patients with this condition. Methods: A consecutive sample was formed from patients who sought treatment at the Dentistry Screening Service of FSG Centro Universitário, between the months of August 2015 and September 2015, where they answered a questionnaire with objective questions about their perception of breath, and attitudes related to social situations where the breath can be influential. Results: Participated in this survey a total of 102 patients. Of these, 27 (26.5%) were male and 75 (73.5%) were female. When asked about the importance and concern for their breath, 95 (94.1%) participants reported that the smell of breath has great importance in their lives and 96 of these patients (95%) have a high concern for the own breath. Conclusion: On patients' perceptions, halitosis affects the quality of life of people. However, other studies should be conducted in order to evaluate the influence of halitosis in the quality of life of patients with this condition.Descriptors: Halitosis; Quality of Life; Health Education.ReferencesPham TA, Ueno M, Zaitsu T, Takehara S, Shinada K, Lam P.H, Kawahuchi Y.

Relevance. Modern data confirm multimicrobial etiology of oral malodor that can significantly compromise effective therapy. Thus, it is relevent to perform comprehensive study of causes of oral malodour, based on microbiological study of composition of mixed microbial biofilms including culturable and non-culturable microbes and evaluation of efficacy of mouth rinses with broad-spectrum antimicrobial agents.Purpose. To study oral microbiota in oral malodor and its correction with antibacterial mouth rinses.Materials and methods. Subjects, involved in the study, were divided into 3 groups, each having 20 people. Controls didn’t use mouth rinses; experimental group used mouth rinse, containing multicidum; in comparison group chlorhxidine containing mouth rinse was used. Orgnoleptic measurement based on 0-5 Rosenberg scale was applied to score intensity of oral malodor. Coating of the root of the tongue was studied by culture-based methods.Results. The research showed that Multicidum® mouth rinse in comprehensive oral malodor treatment affects aerobic bacteria involved in the pathologic process causing bad breath. Positive effect manifested itself organoleptically according to Rosenberg scale in foul breath reduction and in composition changes of microbiota of the root of the tongue. At thus, amount of microorganisms producing smelly volatile compounds decreased and the number of bacteria inhibiting this process increased amid reduction of spore-forming bacteria that contribute to maintenance of stable microbial communities in oral malodor.Conclusion. Gram-positive cocci and Bacillus-Streptococcus, Enterobacter, Staphylococcus, Granulicatella adiacens, Rothia and aerobic spore-forming bacteria from the Bacillus family that are involved in maintaining the functions of resistant bacterial communities-predominated among the bacteria identified in patients with halitosis. There was a statistically significant decrease in the severity of halitosis under the action of a rinse aid, the main active substance of which is Multicidum , and the absence of a statistically significant effect when using a rinse aid based on chlorhexidine.
