RESUMO

Halitosis is a widespread condition presenting several social and psychological implications, leading to a reduction in the quality of life of an individual. Halitosis, per definition, defines an unpleasant smell of the exhaled air, independent of its etiology. It can have a long-term prevalence or be transient, making it difficult to establish this symptom's epidemiology. Oral malodor can be attributed to a high local concentration of intraoral microbial populations, particularly those of the tongue's biofilm, as well as the biofilms associated with teeth and periodontal tissue. Frequently, the treatment options rely on improving oral health via tongue cleaning, detecting periodontal diseases, insufficient dental restorations, alternating diets, and/or alleviating local factors. Different methods targeting specific bacteria species have been designed to improve this condition. The aim here is to underline the correlation between oral biofilms and halitosis, describing prime bacteria species influencing oral malodor and addressing new concepts to ameliorate this condition.

RESUMO

PURPOSE: In the Union for International Cancer Control classification, extrinsic muscle involvement in oropharyngeal cancers is systematically defined as a T4a tumor, although the term extrinsic may incorrectly imply that these muscles are outside the tongue. Our aim was to describe the topography of extrinsic tongue muscles and show that their involvement in oropharyngeal cancers does not always correspond to T4a staging. METHODS: This cadaveric study was based on dissections of the tongues of ten healthy subjects. Dissections were carried out using sections, and careful macroscopic examination with a 3.5-diopter magnifying glass allowed the identification of muscles from their origin to their termination. Imagery and histology were excluded to stay as close as possible to the clinical evaluation. RESULTS: The sample comprised seven men and three women, with a mean age 82 years. In all the ten cases, the extrinsic muscles were located at the periphery of the tongue. The genioglossus was the only deep extrinsic muscle, extending to the periphery and under the mucous membrane of the tongue. As a result, a T1 tumor can invade the mucous membrane and affect the extrinsic muscles without transforming into a T4a tumor. CONCLUSION: As extrinsic tongue muscles are peripheral and submucosal, the use of the term "deep" is erroneous, as is the systematic usage of extrinsic muscles to define T4a oropharyngeal cancers. This study attempts to explain this error, which is recurrent in the different editions of the Union for International Cancer Control and American Joint Committee on Cancer.

RESUMO

BACKGROUND: Oral myofunctional therapy (MFT) is an effective treatment for mild-to-moderate obstructive sleep apnoea (OSA) in middle-aged patients. However, few reports have described its use in elderly patients with moderate and severe OSA. Moreover, no studies have examined the relationship between changes in tongue pressure with MFT and the severity of OSA. OBJECTIVE: We conducted an interventional study using MFT to evaluate the effect of MFT on middle-to-senior-aged patients with moderate or severe OSA and compared changes in apnoea-hypopnea index (AHI) and tongue pressure. METHODS: Thirty-two OSA patients (≥45 years) treated with continuous positive airway pressure (CPAP) were included. MFT was performed in parallel with CPAP. Three days after CPAP discontinuation, polysomnographies were performed and tongue pressures were measured before and after MFT. RESULTS: Patients were 69.3 ± 1.5 years old. After 6 months of MFT, AHI decreased significantly from 34.7 to 29.0/h (P = .03), while tongue pressure significantly increased from 35.9 to 45.6 kPa (P < .01). Seven patients (22%), including 6 of the 12 patients with moderate OSA (50%), experienced successful CPAP discontinuation. CONCLUSIONS: MFT can be a useful intervention even among middle-aged to elderly patients with OSA. Increased tongue pressure may have contributed to the AHI improvement.

RESUMO

BACKGROUND: Tongue muscle strength is important for swallowing but decreases with age, in association with reduced skeletal muscle mass. However, the relationships between pharyngeal dynamics and both skeletal muscle mass and tongue muscle strength are unknown. OBJECTIVE: To investigate the effect of reductions in tongue muscle strength on pharyngeal movement during swallowing in patients with dysphagia. METHODS: Subjects were selected from male outpatients ≥65 years old who were examined for the main complaint of dysphagia. Patients with history of neurodegenerative disease affecting tongue movement, cerebrovascular disease or oral cancer were excluded. As a result, 82 men (mean age, 80.6 ± 6.8 years) participated. Skeletal muscle mass index (SMI) as physical parameters and maximum tongue pressure (MTP) as tongue muscles strength were measured. Status and dynamics of the pharyngeal organs, including change in posterior pharyngeal wall advancement (PPWA) when swallowing 3.0 mL of moderately thick liquid, were measured by analysing videofluoroscopic images. Simple bivariate correlation and multiple regression analysis were used to statistically analyse correlations between parameters. RESULTS: MTP showed a significant positive correlation with SMI (r = .43, P < .01). PPWA showed a significant negative correlation with MTP (r = -0.30, P < .01), but no association with SMI. CONCLUSIONS: While tongue muscle strength is affected by skeletal muscle mass, posterior pharyngeal wall advancement is not readily affected by decreases in skeletal muscle mass. Posterior pharyngeal wall advancement may increase to compensate for swallowing function among individuals with reduced tongue muscle strength.

RESUMO

PURPOSE: To evaluate orthodontic treatment outcome in patients treated with a lingual appliance (Incognito™ Appliance System, 3M Unitek, Monrovia, CA, USA) versus patients treated with a labial appliance (Victory series™, 3M Unitek, Monrovia, CA, USA). METHODS: A total of 72 patients were retrospectively analyzed. The complexity of each case was evaluated using the American Board of Orthodontics (ABO) Discrepancy Index (DI), and orthodontic clinical outcomes were evaluated using the ABO Objective Grading System (cast-radiograph evaluation: C­R Eval). RESULTS: The mean total ABO C­R Eval score was 16 ± 9.1 in the labial appliance group and 12.7 ± 5.4 in lingual appliance group (p = 0.152). The mean total ABO-DI scores were 16.3 ± 7.3 and 15.4 ± 6.6 in the labial and lingual appliance groups, respectively (p = 0.445). A significant correlation was observed between the total DI and total C­R Eval scores. CONCLUSIONS: In this particular study and in the hands of two experienced orthodontists, no differences in the finishing quality of orthodontic treatments using the lingual technique or the buccal appliance technique were found. However, further prospective studies with larger sample sizes are necessary in order to generalize these results.

RESUMO

BACKGROUND: There are still only a few therapeutic strategies to improve taste sensation, which is part of oral health and quality of life. OBJECTIVE: Therefore, here we aimed to investigate gustatory functions of healthy subjects performing mechanical tongue cleaning (MTC), an easy-to-perform oral hygiene procedure, to demonstrate taste changes and to describe possible negative side effects. METHODS: Prior to and 14 days following MTC with an Orabrush® , the following tests were conducted in 65 healthy participants including both non-smokers (n = 50, 76.9%) and smokers (n = 15, 23.1%): 'taste strips' test, the Winkel Tongue Coating Index (WTCI), and subjective self-assessment. RESULTS: Among non-smokers, subjective self-assessments of gustatory function (P < .01), halitosis (P = .03) and tongue coating (P < .01) improved after 14 days of MTC; furthermore, they exhibited higher total taste (P < .01) and lower WTCI (P < .01) values. Their age and sex did not correlate with the differences between the pre- and post-MTC WTCI scores; however, differences between pre- and post-MTC total taste values were correlated with age. The total taste value improvements were greater in non-smokers aged 45-91 years than in those aged 20-44 years (P = .01). In smokers, total taste values (P < .01), as well as sweet (P = .03) and sour (P = .04) taste values, were significantly improved after 14 days of MTC. CONCLUSION: Fourteen days of MTC using an Orabrush® can improve gustatory functions in non-smokers and smokers. Therefore, MTC might be a useful, costless and easy option to improve taste and should be considered as a part of the daily oral care.

RESUMO

Difficult airways can be managed with a range of devices, with video laryngoscopes (VLs) being the most common. The C-MAC® Video-Stylet (VS; Karl-Storz Germany), a hybrid between a flexible and a rigid intubation endoscope, has been recently introduced. The aim of this study is to investigate the performance of the VS compared to a VL (C-MAC Macintosh blade, Karl-Storz Germany) with regards to the learning curve for each device and its ability to manage a simulated difficult airway manikin. This is a single-center, prospective, randomized, crossover study involving twenty-one anesthesia residents performing intubations on a Bill 1™ (VBM, Germany) airway manikin model. After a standardized introduction, six randomized attempts with VL and VS were performed on the manikin. This was followed by intubation in a simulated difficult airway (cervical collar and inflated tongue) with both devices in a randomized fashion. The primary end-point of this study was the total time to intubation. All continuous variables were expressed as the median [interquartile range] and analyzed using the Mann-Whitney U test. A 2-way ANOVA with Bonferroni's post hoc test was used to compare both devices at each trial. All reported p values are two sided. The median total time to intubation on a simulated difficult airway was faster with the VS compared to VL (17 [13.5-25] sec vs 23 [18.5-26.5] sec, respectively; 95% CI; P = 0.031). Additionally, on a normal airway manikin, the VS has a comparable learning curve to the VL. In this manikin-based study, the novel VS was comparable to the VL in terms of learning curve in a normal airway. In a simulated difficult airway, the total time to intubation, though likely not clinically relevant, was faster with the VS to the VL. However, given the above findings, this study justifies further human clinical trials with the VS to see if similar benefits-faster time to intubation and similar learning curve to VL-are replicated clinically.

RESUMO

Objective To investigate the expression and clinical significance of phosphatase and tension homolog deleted on chromosome ten (PTEN) and stimulator of interferon genes (STING) in human tongue squamous cell carcinoma (TSCC). Methods The expression of PTEN and STING protein in 65 pairs of TSCC and paracancerous tissues was detected by immunohistochemical EnVision method, and the relationships between PTEN, STING and clinicopathological parameters, overall survival (OS) and prognosis were analyzed by statistical methods. Results Compared with the adjacent tissues, the expression of PTEN in TSCC significantly decreased, and the expression of STING significantly increased. PTEN was negatively correlated with STING. In TSCC, the expression of PTEN and STING were correlated with pathological grade, TNM stage and lymph node metastasis. There were no significant correlations between the expression intensity of PTEN, STING and the gender and age of patients. The low expression of PTEN and the high expression of STING in TSCC tissues were significantly associated with poor prognosis and significantly shortened overall survival of patients. Conclusion TSCC patients with low expression of PTEN and high expression of STING have poor prognosis and short survival time. Combined detection of PTEN and STING expression is helpful to evaluate the degree of tumor progression and patient prognosis.

RESUMO

PURPOSE: The changes in gustatory function resulting from oncological treatment occur mainly after radiotherapy. However, the head and neck tumors, because of the anatomical location of the lesion, can themselves trigger significant changes in the feeding-related functions - including taste. To assess the gustatory function in patients diagnosed with advanced oral cavity and oropharyngeal cancer. METHOD: This descriptive cross-sectional study comprised 31 individuals with advanced oral cavity and oropharyngeal cancer, referred for oncological treatment with radiotherapy, either alone or in combination with chemotherapy. The "taste strips" test was applied; it consists of inserting solutions with four different concentrations each for salty, sweet, and sour tastes, and three concentrations for the bitter taste, on the tongue. RESULTS: Most of the individuals were diagnosed with oropharyngeal cancer. Approximately half of the sample already had taste-related complaints, and more than 80%, swallowing-related complaints. The overall frequency of hypogeusia was 38.7%, in which the bitter taste stood out in its isolated assessment. The association of change in gustatory function proved to be significant in patients in stage T4. CONCLUSION: The decrease in gustatory function in individuals with oral cavity and oropharyngeal cancer was evidenced in this study, especially when associated with tumors in stage T4. Regarding feeding, most of them reported complaints of dysphagia, suggesting the importance of the speech-language-hearing assessment and follow-up, even before the oncological treatment, to minimize the risks of dysphagia.

RESUMO

BACKGROUND: Oral hygiene management of patients with acute stroke is important for preventing aspiration pneumonia and ensuring oral intake. The tongue coating score can be useful for evaluating the oral hygiene level since it reflects the microorganism number on the tongue surface in elderly patients. However, the relationship between the number of oral microorganisms and the tongue coating score in patients with acute stroke remains unclear. OBJECTIVES: We aimed to investigate the relationships between the microorganism number on the tongue surface and oral factors, including tongue coating score, tongue surface moisture level and tongue function. METHODS: This cross-sectional study enrolled 73 patients with acute stroke who were hospitalised at an acute care hospital and underwent dental intervention. Potential explanatory factors, including sex, age, Glasgow Coma Scale score, tongue coating score, tongue surface moisture level, nutrition intake method, number of functional teeth and tongue function, were evaluated. Logistic regression analysis determined their association with the microorganism number on the tongue surface. RESULTS: The tongue coating score (odds ratio: 1.31) and tongue surface moisture level (odds ratio: 1.10) were significantly associated with increased microorganism numbers on the tongue surface. CONCLUSION: The tongue coating score, which reflects the actual number of microorganisms on the tongue surface, could be an effective tool for evaluating oral hygiene level in patients with stroke. Moreover, reducing oral microorganisms in saliva through oral hygiene management, including removing the tongue coating, could contribute towards the prevention of aspiration pneumonia.

RESUMO

Halitosis (bad breath) is caused by a number of volatiles originating, in most cases, in the oral cavity (intra-oral halitosis). These unpleasant smelling gases are volatile sulphur compounds such as hydrogen sulphide, methyl mercaptan and dimethyl sulphide secreted as a result of bacterial metabolism. Bacteria on the tongue dorsum, as well as oral pathologies such as gingivitis and periodontitis, are the main causes of intra-oral halitosis. Saliva has a number of functions that can affect intra-oral halitosis, such as mechanical cleaning, moistening of the oral cavity and antibacterial properties. Very low secretion of saliva (hyposalivation) can affect intra-oral halitosis.

RESUMO

PURPOSE: this study used the ultrasonography of the tongue movements and the dynamic models of speech production to characterize the articulatory gestures of in the production of /l/ at the Brazilian Portuguese in different age groups, comparing them between typical and atypical children. METHODS: the sample consisted of 30 typical and 30 atypical children between ages of four and eight-years-old, who underwent speech-language and ultrasonographic evaluations. The evaluation was realized by recording words reproduction with the sound /l/ and the following vocalic contexts: /a/, /i/ and /u/, repeating six times for each word. The software for recording and analysis was Articulate Assistant Advanced (AAA). The quantitative analysis considered the 42 points that intercepted the tongue curves in each image to describe the articulatory gestures; the estimation of the mean lines of each curve and the confidence intervals between typical and atypical children groups; and the differences between the mean tongue contours curves according to age group. RESULTS: the results presented a tongue tip elevation and dorsal and root retraction in /l/. Typical children, regardless of age, showed a greater refinement of articulatory tongue gestures than the atypical ones. In older children, there was more delimitation in the mean tongue contours from the tongue tip to the root. CONCLUSION: the ultrasonography of the tongue movements is a substantial implement to characterize the articulatory gestures of /l/, to the differentiation between typical and atypical productions in this sound, and observation of the development of the articulatory gestures.

RESUMO

PURPOSE: To determine reference values of orofacial myofunctional condition and orofacial forces in healthy young and adults. METHODS: Fifty young and adults were selected from a total of 316 voluntaries. Participants were assessed with the Orofacial Myofunctional Evaluation with Scores (OMES) for the investigation of orofacial myofunctional condition. The maximum forces of bite, cheeks, tongue (anterior and posterior regions), and lips were assessed with an electronic dynamometer (values expressed in Newtons). Force values were obtained by average of three repeated measurement. The technical error of measurements was calculated for all variables. RESULTS: There were no differences in orofacial myofunctional condition between men and women. Men presented higher values of orofacial forces compared to women. CONCLUSION: The normal values of orofacial myofunctional condition and orofacial forces were determined in healthy and adults Brazilian men and women. The values obtained in this study from healthy Brazilian may help in the diagnosis of alterations in orofacial motor function and contribute for their therapeutic management.

RESUMO

OBJECTIVE: The aim: The purpose of the study was to determine the correspondence between the location of the tongue median line and the degree of distortion of the vertebral column at different levels in children with scoliosis. PATIENTS AND METHODS: Materials and methods: Totally 56 children (30 girls, 26 boys) aged 11-14 years were examined, with a duration of musculoskeletal disorders 1-3 years. For each participant an oral cavity examination was performed, the position of the middle line of the tongue was determined. X-ray images of vertebral column of the patients from investigated groups were analyzed. RESULTS: Results: In the group with 1year duration of the disease 25.02% patients had a violation of the medial line of the tongue, in the group with 2 years of duration of the disease - 65,52% participants had the deviation of the medial line of the tongue, in the group with 3 years of duration of the disease 86.66% of patients had the deviation of the medial line of the tongue. CONCLUSION: Conclusions: This research allows us to recommend paying attention not only to the size, color, state of the papillae of the tongue, but also to the position of the middle line, which distortion may significate the deviation of the vertebral column in different portions.

RESUMO

Objective: To investigate the consistency of Velum, Oropharygneal, Tongue base, Epiglottis (VOTE) scores between two surgeons with similar clinical experience in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with different degree of disease, and to analyze the influencing factors leading to the difference in score. Methods: This was a cross-sectional study. 64 preoperative drug-induced sleep endoscopy (DISE) videos of OSAHS patients during December 2014 to July 2018, from Nanfang Hospital, Southern Medical University were analyzed. The VOTE score was assessed single-blind by two similar experienced surgeons, and the Kappa value between the two scorers was calculated by the third researcher. According to the characteristics of the case, Fisher's exact test or chi-square test method was used to further explore the factors that influenced the consistency. Results: Sixty-four patients were divided into four groups according to the severity of the disease, including mild (7 cases), moderate (30 cases), severe(18 cases), and extremely severe (9 cases). The scores evaluated between two researchers were analysed for consistency. For mild patients, the two scorers were completely consistent in the configuration and degree of obstruction in the velum and epiglottis (Kappa=1). There was no agreement on whether obstruction or not, obstructed configuration, obstructed degree of the oropharynx and tongue base, and presence of velum and epiglottis obstruction. For moderate patients, the two scorers had a good consistency in the configuration and degree of the velum (0.61≤Kappa≤0.80), and there was no consistency in the evaluation of the degree of tongue base and epiglottis (P>0.05). The consistency of the remaining obstructed conditions in the four planes was generally or moderate (0.21≤Kappa≤0.60). For patients with severe OSAHS, the two raters were completely consistent in the evaluation of palatopharyngeal and epiglottic planes for the presence of obstruction, but there was no consistency in the degree of obstruction. Although the degree of obstruction in the oropharyngeal plane can be assessed with good consistency, the consistency of whether the plane was blocked or not was generally not high. In the assessment of other obstructive conditions in the four planes of severe patients, the agreement between the two scorers was moderate or generally. For extremely severe patients, the two scorers were completely consistent in the evaluation of the velum obstruction, but there was no consistency in the degree of obstruction of the oropharynx and tongue base, and the obstruction configuration and degree of the epiglottis. The evaluation of other obstructed conditions in the four planes is good or moderate. Among the patients with severe OSAHS, the difference in the assessment of obstruction of the oropharynx was associated with tonsil size (P<0.05). Conclusion: When physicians with similar clinical experience scored VOTE, the consistency of whether the velum and oropharyngeal planes are obstructed is related to the severity of the disease. Better consistency is observed among more severe OSAHS patients. The reason for the poor consistency of the oropharyngeal plane in severe OSAHS patients OSAHS is due to the difference of the tonsils size. For severe OSAHS patients with small tonsils, the assessment of whether the oropharynx is obstructed should be more cautious.

RESUMO

The objective of this study was to elucidate the dynamic mechanism of infant tongue movement during sucking. We developed an integrated device with sensors for three-dimensional force measurements applied by the tongue to an artificial nipple. Three mini-size built-in cantilever sensors were installed in each of three sides of the regular hexagonal prism (nine sensors in total) inside the artificial nipple. Signals from the force sensors were amplified and displayed on a PC monitor via USB in real time. We conducted measurements using the system and confirmed that signals were outputted from all nine sensors. The output waveforms and force distributions showed that the force applied was larger at the nipple tip than at the nipple root and moved from the nipple root to the nipple tip.

RESUMO

The human tongue is involved in many essential daily activities and is comprised of eight muscles. To date tools for quantifications of the tongue's intrinsic motions are limited. In this study we explored the tongue's motion during a free-exploration paradigm, using a discreet wireless intra-oral wearable device. Six healthy subjects were instructed to freely move the tip of their tongue on the wearable device while attempting to cover the entire surface of the hard palate. The goal of this study is to compose a two-dimensional probability distribution model of the tongue's motion. We conclude that 90-seconds of non-continuous data collection was sufficient for visualizing the two-dimensional probability distribution of the free-exploration paradigm. The results suggest that the subjects concentrate the majority of the motion in the central portion of the palate.
