Enquanto lesões cutâneas do líquen plano (LP) são autolimitantes, suas manifestações orais (LPO) têm comportamento crônico, raramente apresentam remissão espontânea, e podem sofrer transformação maligna, embora subsista controvérsia sobre esta ultima questão. A este respeito, alguns autores têm dado ênfase ao envolvimento da Candida spp. na malignização LPO devido à capacidade deste fungo em produzir enzima carcinogênica N-nitrobenzilmetilamina e sua relativa freqüência em lesões LPO. Adicionalmente, foi investigada a xerostomia que, além de ocorrer com maior freqüência em indivíduos da faixa etária em que o LPO é mais prevalente, é considerado fator predisponente à candidose. Portanto, a correlação entre xerostomia e colonização por Candida spp. apresente relevância de ser investigada. O presente estudo objetivou comparar a prevalência de Candida spp. e xerostomia em 37 pacientes com lesões LPO (grupo LPO) com a de 26 pacientes com lesões inflamatórias não-LPO (grupo não-LPO) e com a de 28 indivíduos sem lesões orais (grupo controle-saudável). Pacientes LPO foram predominantemente indivíduos do sexo feminino com média idade de 50 anos. Presença de xerostomia foi evidenciada em 35,1% dos pacientes do grupo LPO, em 38,5% do grupo não-LPO e em 25% do grupo controle-saudável, não havendo diferença estatisticamente significante entre os três grupos (p > 0,05). Nos três grupos, medicação sistêmica e presença de distúrbios emocionais (ansiedade e depressão) não foram estatisticamente significante associados como fatores ao desenvolvimento de xerostomia (p > 0,05). A presença de xerostomia não foi fator estatisticamente significante de predisposição à colonização por Candida spp. nos três grupos. Colonização por Candida spp foi maior no grupo controle-saudável (53,5%) que nos outros grupos (29,7% no LPO e 26,9% no não-LPO), porém, não houve diferença estatisticamente significante (p > 0,05). Formas clínicas do LPO não foram fatores de predisposição à colonização por Candida spp. Espécie mais freqüentemente isolada nos três grupos foi Candida albicans. Formas não-albicans, especificamente a C. dubliniensis, foram encontradas em três indivíduos do grupo controle-saudável. / While cutaneous lesions of lichen planus (LP) are self-limiting, its counterpart oral manifestations (OLP) are chronic, hardly ever undergo spontaneous remission, and may suffer malignant transformation, though this latter issue still bears some controversy. In this respect, some authors have believed that Candida spp. might play a part in the OLP process of malignant transformation since this fungi has the ability to produce carcinogenic N-nitrobenzilmetilamina enzyme and has been found in OLP lesions. Apart that, xerostomia is considered a predisposing factor to candidosis and occurs more frequently in individuals at an aging in which OLP is more prevalent. Therefore, the correlation between xerostomia and candidosis may be worth it investigating. This study aimed at comparing the prevalence of Candida spp. and xerostomia in 37 patients with OLP lesions (OLP group) with that of 26 patients with inflammatory non-OLP disease (non-OLP group) and with that of 28 subjects without oral mucosal lesions (healthy-control group). OLP patients occurred predominantly in females at a mean age of 50 years. Presence of xerostomia was seen in 35.1% of patients in the OLP group, in 38.5% of the non-OLP and in 25% of the healthy-control group with no statistically significant difference among the three groups (p > 0.05). In all the groups, systemic medication and the presence of psychological disorder (anxiety and depression) were not statistically significant factors associated with the development of xerostomia. The presence of xerostomia was not a statistically significant factor at predisposing the colonization by Candida spp. in the three groups (p > 0.05). Colonization by Candida species was higher in healthy-control group (53.5%) than in other groups (29.7% in OLP and 26.9% in non- LPO), but the difference among them did not reach a statistical significance (p > 0. 05). Clinical forms of OLP were not predisposing factors to the colonization by Candida spp. The most frequently isolated species in the three groups were Candida albicans. Non-albicans forms, specifically C. dubliniensis, was found in three patients in the healthy-control group.

A escolha de entrevistas jornalísticas deu-se em função do uso frequente de processos concessivos em textos desse domínio, por sua função eminentemente argumentativa. Nesta investigação, foram utilizados os pressupostos teórico-metodológicos do Funcionalismo linguístico de vertente norte-americana, que analisa a estrutura interna da língua, bem como a situação comunicativa em que ocorrem os eventos de fala. Para a consecução dos objetivos deste trabalho, a análise tem por base amostras de um corpus de língua oral, coletadas a partir de 70 entrevistas jornalísticas do Programa Roda Viva, selecionadas do site do FAPESP – Fundação de Amparo à Pesquisa do Estado de São Paulo, compreendendo os anos de 2009 a 2006, em ordem decrescente. Dessa forma, faz-se um levantamento dos articuladores sintáticos concessivos que continuam em uso na língua, bem como daqueles que estão aparentemente caindo em desuso, além do registro das prováveis inovações em seu emprego / This work intends to describe and analysis, according to the Functional Theory, the occurrences of concessive constructions in journalistic interviews in order to investigate the use of concessive connectors on oral language texts. It also intends to verify if new concessive constructions are emerging as some studies in written language suggest. In this investigation, the theoretical and methodological assumptions of linguistic functionalism of the American orientation were used. Consequently, this study considers the discourse level in which the concessive clauses are effectively used taking into account the involved syntactic, semantic and pragmatic aspects. To achieve the objectives of this study, the analysis is based on samples of a corpus of spoken language, collected from 70 interviews from Roda Viva program, selected from FAPESP – Foundation for Research of the State of São Paulo – site, between the years 2006 to 2009, in descending order. Thus, it is a survey of concessive articulators which continue to be used in oral contemporary Brazilian Portuguese, as well as those who are apparently disappearing from the language, beyond recording possible innovations in their employment

This essay was implemented with the aim of investigating the different factors that could affect Swedish students in their Spanish studies. More specifically, the study aimed to investigate to what degree certain factors affect the students in terms of oral comunication. For this reason, the essay presents a result regarding oral production, listening comprehension as well as oral interaction. Furthermore, the study aspired to investigate the correlation between time spent in countries where Spanish is the official language and oral communication competence, if there exits such a correlation and if so, to what extent. The method that was used for the investigation was a cuantitative one along with a statistical analysis with approximately 190 participants. Through this method the investigation reached a result which shows the different perceptions of the professors teaching Spanish as a foreign language as well as their students regarding the importance of each factor that affects the students’ oral production. The investigation also proved that there in fact exits a great correlation between the time spent in a Spanish speaking country and oral communication competence, since the students’ perceptions showed that the longer the students spend in a Spanish speaking country, the more their competence increases.

Individuals with advance-stage illnesses frequently face illness or treatment-related adverse effects in the mouth. These adverse effects can have serious consequences. Despite that, the importance of oral care in this population is often overlooked and there are no definitive guidelines as to what kind of oral care should be provided to these individuals. Given that, our study aims were to explore and better understand the oral health-related concerns, perceived oral care needs of palliative care patients and the berries that face in accessing dental care services. We conducted a qualitative description study by recruiting a purposive sample of 11 participants with advanced stage health conditions from the outpatient palliative care services of the University of Iowa Hospitals and Clinics. Data were collected using in-depth, semi-structured interviews using an interview guide. All interviews were fully transcribed, with the data managed with Atlas.ti software to facilitate the analysis. All participants had oral concerns although they varied widely from person to person and their illness statuses. The most significant concerns were related to dry mouth, loose dentures, and eating difficulties. Among those who stated that they would seek dental care if required, they were not planning on seeking dental care even though they had treatable oral problems, suggesting a mismatch between their oral health status and their perceived needs. The frequently observed barriers that prevented them from seeking dental care were their illness and illness related priorities, finances, feeling discriminated against by the dentist, and a dislike towards the dentist. Providing information to the palliative care clinicians about the significance of oral health and its impact, incorporating a dental care provider in palliative care team, and providing timely information to individuals with advanced health conditions may enhance the understanding of their oral health problems and help them better manage their oral health and may enhance their dental care seeking behavior.

English as a Foreign Language (EFL) teachers use different strategies to support language acquisition when teaching. This study focuses on one particular strategy: Oral Corrective Feedback (OCF). It is provided to support learners’ oral language skills, and takes numerous potential forms which can either be implemented implicitly and/or explicitly. According to many studies, recast is the type of OCF most commonly used by EFL teachers. Studies demonstrate however, that recast is the least effective approach for EFL learners’ uptake. The aim of this research study is to investigate how Swedish EFL teachers provide students with OCF. In addition, the intention is also to explore teachers’ and students’ perceptions of the usefulness of OCF for their skills development in English. The focus of this research study is on Swedish primary schools of grades 4-6. Two types of data-gathering methods were used in this study: interviews and observations. The results confirm that both explicit and implicit OCF was provided when observing the teachers’ approaches and strategies in classroom settings. Surprisingly, this research study reveals that recast was not favoured by the Swedish EFL teachers as they considered other types of OCF to be more beneficial to EFL classroom settings.

This study sought to identify the level of oral health literacy held by people who live in transitional and distressed Kentucky Appalachian areas and if this effects how often they are using oral hygiene techniques. Data were also collected to describe the attitudes Kentucky Appalachian adults hold toward oral hygiene and oral health status. Current documentation shows that poor oral health remains a public health threat in this population despite efforts such as school-based sealant programs and increased dental insurance coverage. This study followed a quantitative design and 99 participants were polled using a survey specifically developed for this study's use. Composite median scores and Spearman's correlation values established the existence of a low oral health literacy level across the participant pool, an also documented that oral hygiene techniques are not used in frequencies recommended for proper oral health. A poor self-efficacy towards the ability to utilize these techniques properly was also identified. Using the Mann-Whitney U test, responses were compared based on county designation and few significant differences were found. These findings show that oral health status and related beliefs are similar across the region and not just isolated to the economically poorest areas as the currently available literature suggests. Applying the health belief model it is predicted that Kentucky Appalachians are unlikely to adopt proper oral hygiene habits until their self-efficacy is improved. A recommendation of this study is that public health officials should promote personal control when designing public health programs geared towards improving the oral health status of this population. To do so would introduce a positive social change in that people with good oral health are less likely to experience the pain, malnutrition, and negative social stigma that is associated with poor oral health.

Objectives: Aim of this systematic review was to assess oral health-related quality of life (OHRQoL) of patients after stroke. Methods: The systematic literature search was performed on December 2021 based on PubMed, Medline, Web of Science, and Scopus, with the search terms: “oral health-related quality of life” AND stroke OR apoplexy OR ischemic stroke OR apoplectic insult. Articles exclusively examining patients after stroke and reporting a well-documented and valid OHRQoL measurement were included. Results: Out of 68 findings, 8 studies were included. The number of patients ranged between 31 and 549 individuals, mean age between 55.7 and 73.9 years, and 49–72% of individuals were male. Two studies included a healthy control group. Oral health parameters were rarely reported across studies. Five studies reported on the Oral Health Impact Profile (OHIP) 14 for OHRQoL, showing means between 2.87 and 33.0 in sum score. Three studies applied Geriatric Oral Assessment Index (GOHAI), with sum scores between 45.6 and 55.0. Only one study found worse OHRQoL in stroke patients compared to healthy controls. Two studies reported on an association between OHRQoL and general quality of life. Three studies found OHRQoL to be associated with different oral health parameters. Only one study found OHRQoL to be associated with stroke-related parameters. Conclusions: Patients after stroke show a reduced OHRQoL. Medical staff and caregivers should support oral hygiene and dental visits, to foster patients’ oral health and OHRQoL.

Oral health may serve as an indicator of overall systemic health, with each disease or condition manifesting differently in the oral cavity. Sickle cell disease (SCD) is a genetic disorder in which sickled red blood cells cause blood vessel occlusion and potentially bleeding in specific sites (e.g., gastrointestinal and intracranial bleeding). With SCD being one of the most common hereditary diseases in the world, it is essential to understand the disease and improve awareness to better treat this population. While studies have been done to evaluate the oral health of persons with SCD, few have explored the occurrence of gingival bleeding and their experience with dental care. Due to this gap in the literature, the present study investigates the potential relationship between SCD, gingival bleeding, and certain other oral manifestations. Adults with and without SCD responded to an online questionnaire regarding oral health and dental care. The data was collected and analyzed during the 2022 spring semester. The data collected from Qualtrics was downloaded into JASP for statistical analysis. While there was a greater prevalence of gingival bleeding and caries in those with SCD, analysis of the sample showed no significant association between the oral manifestations and SCD. A deeper subgroup analysis suggested that those with SCD and no employment may be at higher risk for dental caries, orofacial pain, and gingival bleeding. Further investigation is necessary to determine the direct effect of the disease. The findings may justify further studies to include clinical evaluations by oral health care providers and larger quantity of participants. A better understanding of the relationship between SCD and oral health may lead to oral hygiene improvement strategies geared explicitly toward persons with SCD.

Van die bestaande toetse en metodes vir die evaluering van mondelinge taalvaardigheid is ontleed. 'n Alternatiewe model vir die ontwikkeling van 'n toets of metode wat die evaluering van mondelinge taalvaardigheid so geldig en betroubaar moontlik behoort te maak, is ontleed. Die probleme wat met so 'n evalueringsmetode gepaard sou gaan, is ontleed en moontlike oplossings daarvoor is gevind. Riglyne vir die ontwikkeling en die standaardisering van toetse in die algemeen en van mondelinge taalvaardigheid in die besonder is verkry. Onderwerpe waaruit 'n toets vir die evaluering van mondelinge taalvaardigheid in Afrikaans saamgestel kon word, is geskryf, gekeur en volgens spesifieke voorskrifte eksperimenteel uitgetoets. Die mondelinge taaluitinge is op klankkasset opgeneem en volgens vaste riglyne geevalueer. Statistiese verwerkings is uitgevoer en op grand van die verkree resultate is agt toetsvorms saamgestel. Een van die toetsvorms is saam met 'n ongestandaardiseerde mondelinge taalvaardigheidstoets en 'n objektiewe taaltoets, wat as kriteria vir die geldigheidsbepaling daarvan moes dien, in die praktyk toegepas. Dieselfde vorm is daarna saam met 'n tweede vorm van die toets toegepas om ook die geldigheid daarvan te bepaal. Na aanleiding van die empiriese gegewens is gevolgtrekkings oor die geldigheid en ander statlstiese eienskappe van die toets gemaak. Op grand daarvan is spesifieke aanbevelings oor die gebruik van die toets as model vir die evaluering van mondelinge taalvaardigheid gemaak. / In this study the development of a measuring instrument for the evaluation of oral language proficiency was investigated. Relevant literature was studied to reach a better understanding of the term oral language proficiency and in particular, its relevance to effective communication, the problems underlying oral language proficiency, the teaching thereof and the problems inherent in its evaluation. The requirements for a measuring instrument in general, and for the evaluation of oral language proficiency in particular, and the factors which influence such measurement were also investigated. A number of existing tests and methods for the evaluation of oral language proficiency were analysed. An alternative model for the development of a method to improve reliability and validity in the evaluation of oral language proficiency was examined. The problems connected to such a method were analysed and possible solutions were suggested. Guide-lines for the development and standardization of tests in general, and of oral language proficiency tests in particular, were recommended. Suitable topics for inclusion in a test for the evaluation of oral language proficiency in Afrikaans were compiled, selected and applied on an experimental basis according to specified directions. The oral responses of the testees were recorded on sound cassettes and evaluated according to specified directions. Statistical calculations were executed and on the basis of the results, eight test forms were finalized. One of the test forms, together with a non-standardized oral language proficiency test and a standardized objective language proficiency test which served as criteria for the determination of the validity of the test, was applied officially. The same test form, together with a second form of the test, was subsequently applied to a different group of testees in order to determine the validity of the second test form as well. On the basis of the empirical data, conclusions about the validity and other statistical characteristics of the test could be made. This in turn led to specific recommendations concerning the use of the test to serve as a model for the evaluation of oral language proficiency. / Educational Studies / D. Ed. (Empiriese Opvoedkunde)
