Orofacial muscles activity in children with swallowing dysfunction and removable functional appliances
2019
Swallowing dysfunction is a frequent disorder among children and refers to an altered tongue posture and abnormal tongue movement during swallowing. Removable functional appliance is one of the treatments applied by dentistry to correct this disorder. The aim of this study was to evaluate any differences on orofacial muscles activity in children with swallowing dysfunction with and without removable functional appliances. 68 children were eligible for the study and divided into the orthodontic group (OG) and the no-orthodontic group (NO-OG). Both groups performed a dental occlusion-class evaluation, a swallowing function test and a myoscan analysis in order to measure perioral forces (i.e. …
Retro-nasal aroma release is correlated with variations in the in-mouth air cavity volume after empty deglutition.
2012
International audience; We hypothesized that interindividual differences in motor activities during chewing and/or swallowing were determining factors for the transfer of volatile aroma from the in-mouth air cavity (IMAC) toward the olfactory mucosa. In our first experiment, we looked for changes in IMAC volume after saliva deglutition in 12 healthy subjects. The mean IMAC volume was measured after empty deglutition using an acoustic pharyngometer device. Based on the time course of the IMAC volume after swallowing, we discerned two groups of subjects. The first group displayed a small, constant IMAC volume (2.26 mL ±0.62) that corresponded to a high tongue position. The second group displa…
Language and Mind : towards a linguistic and critical study of spectacular language.
2021
He thesis focuses on a sample of written messages drawn from the daily environment. In the general framework of the relationship between language and power, the thesis consists in the analysis of written messages broadcast in daily life. The research is based on the collection of messages found on various media, including advertising displays. The thesis begins with the reception and use of the notions of newspeak and wooden tongue in their historical and contemporary context in order to show the topicality of linguistic and sociological questions about the relationship between language and power. The study of these two notions, through the linguistic and epistemological issues they involve…
Prognostic value of immunoexpression of CCR4, CCR5, CCR7 and CXCR4 in squamous cell carcinoma of tongue and floor of the mouth.
2018
Background Diverse studies have evidenced that chemokines can play a critical role in pathogenesis of oral squamous cell carcinoma (SCC). The main chemokines involved in oral carcinogenesis, tumor invasion and metastasis are CCR4, CCR5, CCR7 and CXCR4, and our aim was to evaluate the prognostic value of the immunoexpression of these chemokines in SCC of tongue and floor of the mouth. Material and Methods A retrospective descriptive study of the immunohistochemical expression of CCR4, CCR5, CCR7 and CXCR4 in paraffin-embedded samples of 124 patients with SCC of the tongue and floor of the mouth was performed, considering 98 cases from Brazil and 26 cases from Chile. Associations between vari…
Development of a Prognostic Model for Tongue Squamous Cell Carcinoma
2019
One of the objectives of current researches is to be able to customize the treatment of cancer patients. This can be possible only by better stratifying patients based on the most significant prognostic factors [1]. [...]
Risk factors associated with tongue lesions:a propensity score-matched case-control study
2021
Background to analyse the potential risk factors of tongue lesions, comparing the results with a control group. Material and Methods An observational, case-control study was designed. The study included a case group comprising 336 patients with tongue lesions and 336 sex and age-matched controls. We recorded tobacco/alcohol habits, presence of dentures, allergies, medical conditions, and medications. Statistical analysis was performed via logistic regression models to estimate the odds ratio (OR) adjusted for gender, age, tobacco, and alcohol using propensity score-matching analysis (PSM). Results According to the final PSM model, patients with tongue lesions were more likely to suffer from…
Non-specific oral and cutaneous manifestations of coronavirus disease 2019 in children
2020
Background Coronavirus Disease 2019 (COVID-19) seems to affect children only marginally, as a result, there is less knowledge of its manifestations in childhood. The purpose of this retrospective cross-sectional study was to investigate the oral and cutaneous manifestations in children affected by COVID-19. Material and Methods All the medical records of children with COVID-19 admitted to the Pediatric Clinic- ASST Spedali Civili of Brescia from March to April 2020 were reviewed. The following data were recorded: age, temperature, clinical presentation, oral mucosa lesions, taste alteration and cutaneous lesions. Results The medical records of twenty-seven pediatric patients (mean age 4,2 y…
Association between masticatory ability and oral functions.
2020
Background Mastication is the process of breaking ingested food with the teeth and mixing it with saliva to form a mass that is easy to swallow. However, few studies have reported on oral functions, such as occlusal force, tongue pressure, and mastication. The purpose of this study was to evaluate the association between masticatory function and oral functions, such as occlusal force and tongue pressure. Material and Methods In this study, there were 113 patients (41 men and 72 women; mean age, 68.4 ± 11.3 years) who visited dentists at the Hiroshima University Hospital, Hiroshima, Japan between April 2015 and November 2018. Masticatory function of the patients was evaluated using a mastica…
Airways cephalometric norms from a sample of Caucasian Children
2021
Background: The diagnosis of the respiratory pattern and the analysis of airway dimension using lateral cephalometric radiographs include the study of the adenoid region, free air space of the nasopharynx and oropharynx, soft palate and posterior part of the tongue. The objective of this study is to identify the airways cephalometric norms from a sample of Caucasian children, in relation to gender, age and type of malocclusion. Material and Methods: A total of 480 patients of both sexes were included in the study, the age ranged between 6-12 years. The radiographic records were analyzed using the Nemoceph® 11.3.0 software and the diagnosis of skeletal class was performed using the Steiner a…
Can tongue position and cervical ROM affect postural oscillations? A pilot and preliminary study
2020
The tongue is considered an important part of the postural system, so it is fundamental to understand how it can interfere with the humans’ postural oscillations. The aim of this preliminary investigation is to understand the effects of different tongue position and cervical ROM on postural oscillations measured in a stabilometric test. Thirteen voluntary subjects were recruited (30.8 ± 9.7 yrs.; 173.6 ± 14.9 cm; 72.6 ± 15.6 kg) and tested in three different random tongue conditions: comfortable tongue position (CT), palatal spot position (ST) and low tongue position (LT). All tests were performed with open eyes. Stabilometric test were performed with a pressure platform. In addition, the c…
