Vampirismo y sexualidades marginalizadas en dos relatos de Gabriela Rábago Palafox
Authors: Arango Vallejo Álvaro
Published: December 2021

El propósito de este estudio es explorar cómo las representaciones vampíricas en los relatos “A cadena perpetua” y “Criaturas de la noche”, de la escritora mexicana Gabriela Rábago Palafox (1950-1995), fungen como mecanismo para tematizar, respectivamente, la homosexualidad y la violencia de género, proveyendo una postura crítica contra la discriminación y estigmatización social en torno a las mismas. Para lograr esto, se analizará la esencia transgresora del vampiro en medio de la tensión entre sus raíces literarias en la Europa del siglo XVIII y su reescritura en un contexto latinomaericano y contemporáneo, ilustrando cómo las funciones trangresivas del horror literario pueden reflejar posiciones exteriores a un discurso hegemónico, convirtiéndose en potenciales herramientas valiosas para dar voz a grupos marginalizados.
Recuerdos de futuras Promesas naturales, o cómo vivir bajo los condicionamientos de una resiliencia deshumanizante
Authors: Paolini Vincenti Claudio Alfonso
Published: December 2021

El artículo pone foco en la novela distópica Promesas naturales (2006) de Oliverio Coelho y en el modo en que la protagonista encauza su proceso de resiliencia (Evans y Reid), entre otros factores, articulado por un estado totalitario y deshumanizante; también, en la forma en que el sistema produce seres monstruosos. Si bien el relato no hace referencia explícita a espacios identificables, algunas marcas socioculturales y lingüísticas dan lugar a que se pueda interpretar como una alegoría de cómo hubiese sido el presente y futuro de algunos países de la región sur de América Latina (Argentina, Chile y Uruguay) si los procesos dictatoriales (durante los años 70 y 80 del siglo pasado) se hubieran prolongado por generaciones.
Análisis de la BSO de Akelarre
Authors: Martín Pérez Yolanda
Published: December 2021

La película Akelarre, producida en 2020 y dirigida por Pablo Agüero, ha ganado cinco premios en los Goya 2021, uno de ellos el Goya a la mejor música original, entre otros importantes premios. Este drama, ambientado en la caza de brujas por parte de la Inquisición en el País Vasco del siglo XVII, presenta una música original compuesta por Maite Arroitajauregui y Aránzazu Calleja. En este trabajo se realiza un estudio del interesante proceso de composición musical de forma conjunta por estas dos compositoras y un análisis de la banda sonora musical de la película, para centrarse, finalmente, en la influencia de la cultura y la música tradicional vascas, aspectos sobre los que no existe ningún trabajo publicado hasta el momento.
La BSO de Akelarre comprende música, principalmente diegética e interpretada por las protagonistas, inspirada en canciones tradicionales vascas de la época, e incluye el uso de instrumentos populares de dicho contexto. Prácticamente toda la música de la película, tanto incidental como las canciones populares, está basada en un tema principal que está compuesto a partir de una canción tradicional extraída de un cancionero vasco. En esta investigación se realiza un análisis musical y cultural de todos estos elementos, con una metodología basada no solo en un estudio pormenorizado de la película y de su BSO, sino también en una entrevista con Maite Arroitajauregui, la compositora que se dedicó a crear las obras musicales de la película centradas en el folklore vasco.
ANTIOXIDANT SUPPLEMENTS IN ALZHEIMER’S DEMENTIA AND MILD COGNITIVE IMPAIRMENT: A SYSTEMATIC REVIEW
Authors: Pegg E.J.
Published: December 2021

Objective: Current treatments have only a modest effect on impairment in Alzheimer’s Dementia (AD) and there is no treatment currently licensed for Mild Cognitive Impairment (MCI). Oxidative stress is postulated to play a role in the pathogenesis of AD and MCI and this provides a rationale for treatment with antioxidant supplements. The aim of this review is to evaluate the effect of antioxidant supplements in people with AD and MCI. Methods: A systematic review of published randomised controlled trials was carried out. 4 electronic databases were searched. Studies were included if they compared the use of a placebo with the following antioxidant supplements in people with AD or MCI: Vitamin e, vitamin c, selenium, alpha lipoic acid, phenols, zinc, curcumin, beta carotene, coenzyme Q10, melatonin. The primary outcome measure was cognitive impairment. Secondary outcome measures included functional impairment, behavioural disturbance and safety. Results: 10 trials were identified which met the inclusion criteria. Outcome data was not suitable for meta-analysis. 5 studies reported a small positive treatment effect on cognition and 1 reported a negative effect. 2 reported a positive treatment effect on functional ability and 1 on behaviour. There were no consistent adverse effects found overall however two studies raised concern of possible worsening of cognition in certain circumstances. Conclusions: The findings of this systematic review do not support the use of antioxidant supplements to slow cognitive, functional or behavioural deterioration in people with AD or MCI. However the majority of included studies had a high or unknown risk of bias. In the one study which had a low overall risk of bias, there was evidence that antioxidant supplements may have a positive effect on functional decline in AD. The overall risk of harm associated with short term antioxidant supplementation appears to be low however caution is warranted. Further studies evaluating the role of oxidative stress in the pathogenesis of AD are suggested.

Abstract: The aim of our study was to evaluate a hypercaloric sweet milkbased oral nutrition supplement in a prospective 3 day-study designed to assess the taste preferences of this oral nutritional supplement (ONS) in elderly malnourished out-patients and the influence on adherence in daily intake during two months.A total of 28 out-patients with recent weight loss were included in this study. One flavour (chocolate, vanilla or strawberry) was administered each day in a random way during three consecutive days. In the first three days, patients were asked to fulfill two questionnaires in order to reflect ONS tolerance and acceptance. Sweet and aftertaste were better for chocolate flavour than for vanilla or strawberry flavours. Patients who chose vainilla took a total of 96.3+7.4 average bricks during outpatient followup (1.60+0.3 per day), patients who chose chocolate took 76.8+15.0 bricks (1.28+0.8 per day) and patients who chose strawberry bricks taken 60.3+19.5 bricks (1.10+0.7 per day), with a significant difference with vainilla flavour (p <0.01). The improvement of weight (vanilla +1.0+0.8 kg vs chocolate +0.5+0.8 kg vs 0.6+1.0 kg:p=0.03), tricipital skinfols (vanilla +1.5+0.3 mm vs chocolate +1.1+0.4 mm vs 0.7+0.3 mm:p=0.03), prealbumin levels (vanilla +4.2+0.8 mg/dl vs chocolate +3.9+0.7 mg/dl vs +3.6+1.0 mg/dl:p=0.01) and transferrin levels (vanilla +100.0+21.8 mg/dl vs chocolate +75.5+18.8 mg/dl vs 63.8+14.1 mg/dl:p=0.03) was higher in patients treated with vanilla ONS than chocolate or strawberry ONS. The three flavoured ONS taste preferences are similar although the consumption is high in vanilla flavoured ONS.

The present study was designed to evaluate intra-abdominal adiposity in rats subjected to early weaning and subsequently treated with diet containing flour or flaxseed oil until young life. Pups were weaned for separation from mothers at 14 days (early weaning, EW), and 21 days (control, C). After 21 days, control (C60) was fed with control diet. EW was divided into control (EWC60); flaxseed flour (EWFF60); flaxseed oil (EWFO60) diets until 60 days. At 21-60 day, intra-abdominal fat mass were evaluated. At 60 days, retroperitoneal adipocyte area was determined. At 21 days, EW group displayed lower (P<0.05) intra-abdominal fat mass. At 60 days, EWC60 group displayed lower (P<0.05) intra-abdominal fat mass. Adipocytes area were lower (P<0.05) in experimental groups. EWC60 displayed lower (P < 0.05) adipocytes area (vs. EWFF60 and EWFO60). Flour and flaxseed oil diets contribute to recovery of intra-abdominal adiposity after precocious interruption of lactation.

Published: December 2021

Background: Sarcopenia classification is important for prevention or intervention of sarcopenia in the elderly. However, measures used for the current sarcopenia criteria, including muscular strength, could be impacted by forms of arthritis. Thus, it is crucial to understand the impact arthritis has on sarcopenia status. Objectives: The aim was to investigate if arthritis relates to sarcopenia classification via grip strength or single chair stand in older women. A secondary aim was to assess the relationship between grip strength and upper and lower body strength in those with arthritis. Design: A cross-sectional analysis. Setting and participants: Sixty-one community-dwelling older women (71.9±4.6 years) from Rhode Island. Measurements: Sarcopenia status was classified using established working definitions. Grip strength was measured using a hand grip dynamometer, chair stands were measured via a single chair stand test, and gait speed was assessed using a four-meter walk test. A segmental multi-frequency bioelectrical impedance analysis assessed body composition and arthritis status was based on self-report. Upper and lower body muscular strength were measured using a chest press and leg press one repetition maximum. Results: No associations were observed between arthritis and sarcopenia status (p=0.36) nor arthritis and upper or lower body muscular strength and grip strength. Conclusions: The results of this study may indicate that arthritis is not associated with sarcopenia status but may affect other measures of muscular strength.

Published: December 2021

Objectives: To determine household food insecurity and dietary diversity (DD) among seniors in Lubbock, Texas and examine the relationships between food security status and DD. Design: Cross-sectional study design. Setting: Lubbock, Texas. Participants: 200 seniors (≥ 50 years) randomly selected from seven senior centers and Meals on Wheels. Measurements: Socio-demographic and economic questionnaire, the validated Household Food Insecurity Access Scale (HFIAS) for food security and coping strategies, the validated DD scale for measuring the minimum DD for women (MDD-W), and weight and height measurements. P<0.05 considered significant was used for all statistical analyses. Results: The majority of the respondents (59.8%) were categorized as food secure. No significant relationships were observed between DD and HFIAS. The linear regression analysis carried out on the socio-demographic predictors of food security showed that age, household income and money spent on food per month were predictors of food security (R2= 0.233; p<0.000; SEE=4.462). The number of people in the household was the only predictor for DD score (R2= 0.028; p<0.000; SEE=1.929). Conclusions: This study showed a serious problem of household food insecurity among seniors in Lubbock, Texas affecting 40% of seniors. The results provide some of the first insights into seniors’ food security status and DD. No relationship could be established between food security status and DD in this study. Only household size was a predictor for DD in this study and further research is needed to determine quantity of dietary intakes and factors influencing the dietary patterns.

Published: December 2021

Background: An increased risk of cognitive decline in the elderly with B12 deficiency has been associated with excessive synthetic folic acid in food fortification and supplements. Objectives: To assess the dietary folate and folic acid intake from food fortification, as well as serum vitamin B12, folate, iron, and homocysteine concentrations among the elderly and their relationships with cognitive changes. Design: Cross-sectional, observational study. Setting and Participants: Community-dwelling elderly (N = 40), predominantly female (90%), with an average age of 69 years. Measurements: Dietary intake information was collected using four 24-hour dietary recalls, adjusted for iron and folic acid in fortified flour and supplements. Serum vitamin B12, B6, folate, iron, and homocysteine concentrations were determined. Cognitive function was assessed using the Mini-Mental State Examination, adjusted for educational level. Results: Possible serum vitamin B12 deficiency (<258 pmol/L) was present in 5% of the elderly participants, while 27.5% had possible functional deficiency (<400 pmol/L). No serum folate deficiency (<6.8 nmol/L) was observed; however, 15% had possible deficiency (<13.6 nmol/L), and 7.5% had supraphysiological levels. Hyperhomocysteinemia (≥15 µmol/L) was present in 65% of the sample. Almost half of the participants (47.5%) showed cognitive impairment. There were no significant relationships between the Mini-Mental State Examination results and the B12, folate, iron, and homocysteine concentrations. However, the participants with serum vitamin B12 levels <400 pmol/L tended to have poorer Mini-Mental State Examination scores, which were related to older age (P = 0.045) and changes in the oral cavity (P = 0.034). In addition, folic acid consumption was inversely related with serum vitamin B12 levels (P = 0.030). Macrocytosis was not observed. Conclusions: Although Mini-Mental State Examination-assessed cognitive impairment was not related with the investigated biochemical variables, increased folic acid consumption seems to have a negative impact on vitamin B12 metabolism; therefore, fortification may be contributing to functional disability and masking hematological signs in the elderly.

Published: December 2021

The purpose of this study was to assess the effects of post-polymerization heat on the flexural strength of direct composites. Direct composite specimens (n=10), measuring 25×2×2 mm (Z-250 and P-60), were polymerized by 3 methods: (1) light-polymerized for 40 seconds, (2) (1) + post-polymerization in an oven at 120ºC for 20 minutes, and (3) (1) post-polymerization in an autoclave at 120ºC for 20 minutes. Specimens (n=10) of the indirect composite Artglass (control group) were polymerized in a UniXS oven. Specimens were stored in distilled water for 24 hours at 37ºC and then submitted to a flexural 3-point bending test with a universal testing machine. Flexural strength (MPa) data were analyzed by one-way ANOVA and Tukey´s multiple comparison test (α=.05). Results showed that (1) additional heat polymerization in an oven provided significantly (p<.05) higher flexural strengths (Z250: 158.85 MPa and P60: 147.10 MPa) than that of the Artglass resin (121.52 MPa); (2) with additional heat polymerization in an autoclave, these direct resins presented mean flexural strengths (Z250: 134.54 MPa and P60: 130.18 MPa) similar to that of Artglass (P>.05); (3) groups that were only light-polymerized (Z250: 124.75 MPa and P60: 128.96 MPa) were similar to Artglass (P>.05). When composites were only light-polymerized, they showed a flexural strength behavior similar to that of the indirect composite Artglass. The post-polymerization heat do not enhanced the resistance of the Filtek P60, but increased the strength of the Filtek Z250 when additional heat polymerization in a oven
Análise de testes empregados no estudo da adaptação marginal de próteses sobre implantes: proposição de novos conceitos e parâmetros

Published: December 2021

Um dos maiores obstáculos para o sucesso das reabilitações sobre implantes consiste na obtenção de boa adaptação marginal dos componentes protéticos. Não está claro na literatura quais níveis de desajuste são considerados clinicamente aceitáveis, mas sabe-se que desadaptações protéticas podem provocar problemas mecânicos e biológicos. O presente estudo tem como objetivo utilizar testes classicamente empregados nas pesquisas científicas para calcular e propor a obtenção de diferentes parâmetros de adaptação marginal. Para tanto, analisou-se estruturas metálicas simulando barras para próteses fixas tipo protocolo fundidas em diferentes materiais, mensurando as desadaptações entre as estruturas e os pilares intermediários em microscópio ótico, com o teste de único parafuso, com aperto bilateral alternado nos implantes distais 1 e 5, e com todos os parafusos apertados com um torque de 10Ncm. Esses dados possibilitaram a obtenção de diferentes parâmetros de adaptação marginal: passividade, passividade média, desajuste vertical, redução de desajuste e percentual de redução de desajuste. De acordo com a análise estatística dos resultados (p<0,05), não houve diferenças entre os dados de passividade com aperto em 1 e em 5 para nenhum dos metais utilizados (Ti p=0,421; Co-Cr p=0,635; Ni-Cr-Ti p=0,260). Contudo, houve diferenças significantes entre os valores de passividade e os valores de desajuste vertical para todos os metais empregados (p=0,000), demonstrando que existe uma redução de desadaptação que deve ser levada em consideração. Pode-se concluir que a adaptação marginal deve ser estudada sob diferentes parâmetros, os quais podem possibilitar uma análise mais profunda e detalhada dos problemas relacionados aos desajustes protéticos.

Published: December 2021

O objetivo deste trabalho foi o de verificara influência da opacidade de cor, e aplicação tópica do FFA 1.23% na microdureza da resina composta quando utilizado aparelhos fotopolimerizadores de luz halogena e LED azul. A resina composta Esthet-X (Dentisply), nas cores A2 e A2-O, foi inserida em uma matriz de aço-inoxidável em cavidades de 5mm de diâmetro e 2mm de profundidade e fotopolimerizada por aparelhos; de luz halogena, XL 3000 (3M) ou de LED azul, Optilight LD II (Gnatus), por 40s. Formaram-se 4 grupos com quinze amostras cada, sendo analisadas as superfícies das amostras. Estas foram armazenadas em água destilada, por 24h e posteriormente embutidas em resina acrílica ativada quimicamente. Realizou-se a leitura da microdureza inicial em Microdurômetro Digital Vickers, utilizando 50g de carga por 30s de permanência. A seguir, foi aplicado o FFA 1.23% por 48 min e uma segunda leitura da microdureza foi realizada. Os dados foram submetidos ao teste estatístico de ANOVA e Tukey (5%). Os resultados demonstraram que a aplicação tópica do FFA 1.23% promoveu uma redução signifi cativa nos valores médios de microdureza da resina A2 e A2-O. O uso das fontes de luz halógena e LED e o emprego de diferentes opacidades não promoveram diferença signifi cante na microdureza superfi cial na resina. Concluiu-se que a variação da opacidade da resina e o emprego de diferentes fontes de luz (halogena/LED) não infl uenciaram a microdureza superfi cial, porém a utilização tópica do FFA 1.23% alterou o grau de microdureza da resina.

O objetivo deste estudo foi avaliar o número e o diâmetro de túbulos dentinários em canais radiculares, nos diferentes terços, em dentes humanos, visando auxiliar estudos na área da permeabilidade dentinária. Para tal, foram utilizados 24 dentes humanos prémolares hígidos, divididos em 4 grupos de acordo com faixas etárias - G1: 10-15; G2: 16-30; G3: 31-45: G4: 46-80 anos de idade. Os dentes tiveram suas coroas removidas, sendo os canais instrumentados, seccionados longitudinalmente, submetidos ao ultra-som e lavados com EDTA. Em seguida, foram metalizados e analisados ao MEV. Os dados obtidos foram submetidos aos testes ANOVA e Tukey (5%). Quando analisados os terços radiculares, o cervical apresentou a maior média, seguido dos terços médio e apical. Com relação às faixas etárias, o G3 apresentou a maior média de número de túbulos dentinários, tendo o G4 apresentado uma média signifi cantemente menor que os demais. Não foram encontrados, nos grupos estudados, diferenças com relação ao diâmetro tubular. Concluímos que apenas os grupos G3 e G4 diferiram estatisticamente entre si, com relação ao número de túbulos dentinários.

Published: December 2021

A neurofibromatose ou Doença de Von Reckinghausen foi descrita pela primeira vez em 1882, como uma enfermidade originada da bainha mielínica dos nervos. É uma desordem genética autossômica dominante que ocorre na proporção de um para cada quatro mil nascimentos. É classifi cada como uma das síndromes neurocutâneas mais freqüentes e caracteriza-se pela presença de neurofi bromas múltiplos, manchas café-com-leite, anomalias esqueléticas e envolvimento do sistema nervoso central. O objetivo deste trabalho é apresentar um caso de neurofi bromatose múltipla com acompanhamento clínico de dez anos. O diagnóstico da neurofi bromatose é eminentemente clínico, baseando-se nos critérios estabelecidos pela Conferência de Desenvolvimento do Consenso de Neurofi bromatose em 1987. O tratamento dessa doença, na maioria das vezes, não é satisfatório, no entanto, intervenções cirúrgicas devem ser realizadas quando a função estiver comprometida devido à presença do tumor ou por questão estética. Essa patologia pode causar alterações estéticas e problemas sociais. Por isso, muitas vezes, há necessidade de um acompanhamento psicológico e social dos pacientes afetados pela doença, o que deve ser de conhecimento dos profi ssionais da área da saúde.

Published: December 2021

A imagem digital tem sido utilizada como um importante recurso diagnóstico na Odontologia. A dificuldade no diagnóstico dos defeitos de furca desperta particular interesse, visto que o tratamento está relacionado à extensão do defeito ósseo. Além da qualidade da imagem, a habilidade do observador é essencial para o diagnóstico. Recurso técnico como a densidade poderia auxiliar na análise comparativa das imagens do mesmo defeito, entre os períodos de observação. O objetivo deste estudo foi avaliar a densidade radiográfica como auxiliar na determinação da extensão de defeitos de furca. Foram criados 24 defeitos de furca em dente birradicular mandibular de suínos, com profundidade crescente, numa seqüência de remoção óssea simulando envolvimento de furca grau I, II e III; sendo obtidas imagens digitais a cada passo. Determinou-se a média de densidade dos defeitos (inicial, grau I, grau II, grau III), num total de 96 imagens. Com os valores obtidos foi realizada análise de variância e teste de Tukey para comparação entre os graus de envolvimento de furca. Houve diferença significativa (p<0,001) entre os defeitos: inicial e grau I, II e III; grau II e III. Não houve diferença significativa apenas entre os defeitos grau I e II (p>0,05). A média de densidade para os grupos foi: inicial - 126,98; grau I - 112,52; grau II - 106,22; grau III - 80,63. Concluiu-se que a densidade radiográfica pode auxiliar na quantificação de defeito de furca, constituindo recurso adicional à habilidade do observador.

Published: December 2021

Objective: To evaluate different methods of additional polymerization in the Vickers’ microhardness of three composite resins. Material and Methods: With assistance of a metallic matrix (3 x 4mm), 30 specimens (sps) of each direct resin composite (drc) were prepared, entitled: Filtek Z250(3M ESPE, Saint Paul/MN-USA)(Gr1), W3D(Wilcos, Petrópolis/ RJ-Brazil)(Gr2), and EstheticX (Dentsply/York/PA-USA)(Gr3). All sps were photopolimerized, by the incremental technique, during 40 seconds (Gr1 - n=10: control). After that, 20 samples of each group were divided and half of the samples (n=10) were submitted to the additional polymerization during 15 minutes to 127ºC in autoclave (Gr2) and the other half in stove (Gr3). After all sps were stored in distilled water (37ºC/24 hours). The microhardness was accomplished in digital machine (Future-Tech, FM 700 Model), with 50kg of load. The data obtained (Kg/mm2) were analyzed utilizing the ANOVA Test (2 factors) and Tukey test (p<0.05). Results: The values of mean ± standar  deviations obtained were: Gr1a(84,2±5,1), Gr1b (71,6±6,7), Gr1c (89,6±7,4), Gr2a (101,1±6,0), Gr2b (96,4±9,0), Gr2c (112,6±7,3), Gr3a (74,0±6,5), Gr3b (66,0±12,7) e Gr3c (81,7±6,5). The polymerization in stove produced a higher microhardness than the other kinds of polymerization (p<0.05) and the microhardness of the resins statistically differed among them (p<0.05). Conclusion: The additional polymerization of the Filtek Z250 in the stove produced microhardness statistically higher than the others.

O objetivo deste trabalho foi avaliar in vitro a infiltração marginal de restaurações de compósito utilizando diferentes sistemas adesivos: Adper Single Bond 2 (3M/ESPE), Scotchbond Multi-uso (3M-ESPE), Clearfil SE Bond (Kuraray) e Adper Prompt L-Pop (3M-ESPE). Foram utilizados oitenta dentes bovinos, que foram separados aleatoriamente em quatro grupos, de acordo com o sistema adesivo utilizado. Os dentes tiveram cavidades circulares (2mm diâmetro X 2mm profundidade) preparadas na porção radicular utilizando pontas diamantadas. Os dentes foram restaurados em único incremento de compósito e armazenados por 24 horas ou 3 meses. Após os períodos de armazenagem, os dentes de cada grupo (n=10) foram vedados com duas camadas de esmalte para unha e submetidos a 500 ciclos térmicos (5-55ºC), imersos no corante azul de metileno a 2%. Após, as coroas e terço apical das raízes foram seccionadas e descartadas, ficando apenas a porção do terço cervical e médio. Essa porção que continha a restauração, foi seccionada no sentido vestíbulo-lingual para a avaliação da infiltração marginal através de lupa estereoscópica com 40X de aumento. O critério utilizado para a avaliação da infiltração foi o seguinte: houve infiltração do corante e não houve infiltração do corante. Os resultados foram submetidos ao teste de Fisher e ao teste de McNemar. Não houve diferença significativa entre os sistemas adesivos, seja no período de armazenagem de 24 horas ou de 3 meses, com exceção do Adper Single Bond 2, onde no período de 24 horas houve estatisticamente maior infiltração do que em 3 meses.

This study verified the dimensional changes occurred in stone casts by tri-dimensional design obtained from mathematical calculation. Dental stone casts were made in molds of addition silicone, alginate or impression compound relayed by alginate obtained from an aluminum pattern die. Screws were used to establish reference points of the distances, creating segments for area and volume calculation of the generated figures. Tri-dimensional measurement equipment fitted out with Renishaw PH9 measurement head and TP 200 searcher with 1mm diameter was used for this distance measurement. Computer Aided Design system was used to determine the X, Y, Z coordinates, which permitted to get the geometry dimensions. Results were submitted to statistical calculation and study of the differences (5%). Silicone impression produced casts with smaller dimensional changes and larger repetition capacity. The casts presented small variation of the variables values among the copies, when compared to alginate or impression compound relayed with alginate molds. Alginate produced casts with better copy fidelity, with absolute values of the variables close of the absolute values of the variables of the metallic die. Alginate presented good capacity to copy the metallic die among the impression materials, although in dimensional conditions no similar

O objetivo desta pesquisa foi avaliar a influência da desinfecção química e da armazenagem por 3 meses sobre a deformação inicial, deformação permanente e a porosidade de três materiais reembasadores resilientes. Os corpos-de-prova foram divididos em 2 grupos para cada material: sem e com desinfecção química. Foram analisados em relógio indicador, para a verificação da deformação inicial e permanente e visualmente para a porosidade. Essas leituras foram realizadas 3 meses após a polimerização dos corpos-de-prova. Concluiu-se que todos os materiais reembasadores resilientes sofreram deformação inicial e permanente, após o período analisado, independentemente da desinfecção química. O material que apresentou a menor deformação inicial e permanente foi o Dentuflex. Após 3 meses, apenas o material Dentuflex não apresentou porosidade.

A falta de conhecimento da anatomia da cavidade pulpar é uma das principais razões do insucesso da terapia endodôntica dos caninos inferiores. Foram utilizados 1040 caninos inferiores cuja incidência de bifurcações foi avaliada através de estudo radiográfico e comparada com o método de injeção e diafanização dos mesmos dentes. Também foram estudadas outras características internas visualizadas através da diafanização. Da fase radiográfica concluiu-se que 8% dos caninos inferiores apresentaram duplicação de seu canal radicular. Dos 1017 caninos observados através da diafanização, 8,6% apresentaram canais duplos. Através dos achados conclui-se que o clínico deve realizar sempre um exame radiográfico em várias angulações para detectar a duplicidade do canal radicular dos caninos inferiores antes de iniciar a terapia endodôntica.

Published: December 2021

Verificou-se a densidade óptica de quatro resinas compostas disponíveis atualmente no mercado, bem como a composição desses materiais quanto à presença de elementos químicos responsáveis por sua densidade óptica. As resinas Z250 e Supreme (3M-ESPE), 4Seasons (Ivoclar Vivadent) e EsthetX (Dentsply), foram inseridas em orifícios existentes em 12 placas de acrílico divididas em espessuras de 2 e 4mm. Os incrementos de resina (2mm) foram fotopolimerizados por 40s. Realizaram-se 3 tomadas radiográficas de cada placa com o tempo de exposição de 0,12s. As imagens digitais foram obtidas através do sistema DenOptix. Foram realizadas 3 leituras de cada tomada radiográfica em cada resina no software VixWin, sendo calculada a média dos maiores e menores valores de densidade óptica (em pixels), totalizando 216 leituras. Confeccionaram- se 2 amostras de cada resina para análise dos elementos químicos em Microscopia Eletrônica de Varredura através de Espectroscopia por Dispersão de Energia (EDS). Os resultados foram submetidos ao teste de Shapiro-Wilk, à Análise de Variância, ao teste de Tukey a 1% e Correlação de Pearson. As médias de densidade óptica (pixels) em 2mm e 4mm, respectivamente, foram (valores seguidos de mesma letra não diferem estatisticamente entre si): Z250 = 171,17a e 199,58x; Supreme = 167,78a e 195,30w; 4Seasons = 176,32b e 208,50y; EsthetX = 190,85c e 213,56z. Os maiores valores foram obtidos pela resina EsthetX, nas duas espessuras avaliadas. Com base nos resultados encontrados concluiu-se que não houve correlação entre os valores médios de densidade óptica das resinas testadas e o percentual em peso de elementos que lhe conferem esta característica.

Published: December 2021

O sucesso no tratamento reabilitador protético realizado sobre implantes ósseo-integrados pode ser comprometido por falhas mecânicas em seus componentes, tais como desajuste e até mesmo fraturas dos componentes protéticos quando expostos à função mastigatória. O presente estudo teve por objetivo avaliar, in vitro, o desajuste ocorrido na interface implante-intermediário por meio da aferição e comparação do torque inicial utilizado para a colocação do parafuso de fixação dos pilares protéticos em implantes com hexágono interno, com relação ao torque necessário para remoção dessas estruturas antes e após a simulação da função mastigatória. Testes de ciclagem mecânica foram induzidos sobre os pilares protéticos. Mediu-se o torque de remoção dos parafusos de fixação dos pilares proteticos. Houve diminuição significativa nos valores de torque de remoção de todas as amostras, e a perda foi ainda maior nas amostras submetidas à ciclagem mecânica. Os dados obtidos permitem supor que há sempre diminuição nos valores de torque de remoção desses componentes e que a função mastigatória aumenta a probabilidade de desajuste na interface implante-pilar protético.

Authors: Marchan Shivaughn M , Bascombe Kelee , Hector Trevin , Smith William AJ , Ramnanansingh Terry G
Published: December 2021

Objective: The aim of this study was to assess the in vitro effect of flavored waters on human tooth enamel using a gravimetric method. Lingual surfaces of lower molars were used to obtain enamel specimens. Material and Methods: Enamel (n=3) was washed and dried, immersed in 6 flavors of locally available of flavored sparkling water and assessed using gravimetric analysis, periodically for up to 9 days.  Additionally, pH measurements of the flavored waters were recorded.  Results: All the tested flavored waters showed pH values below that of critical pH. Paired t-tests demonstrated significant reductions in the mean group mass for all enamel specimens from as early as day 1 after immersion in flavored water, compared to baseline measurements. Further reductions in mean mass continued up to day 9 of immersion. Conclusion: Flavored waters are potentially erosive to human enamel specimens with the erosive effect being cumulative over time.KeywordspH; Enamel; dental erosion.
Is it a blessing? The impact of Covid-19 on non-traditional language
learners’ satisfaction at Saudi Electronic University
Authors: Alharbi Amera , Wright Vicky , Borthwick Kate
Published: December 2021

This study examines non-traditional language learners’ interactions and
satisfaction with online learning in the Saudi context during the pandemic.
Saudi Electronic University (SEU) is unique in Saudi Arabia as it has
adopted a blended mode of teaching and students’ completion of both online
and class-based materials is mandatory. It enables non-traditional students
to further their studies. In a quantitative study, 732 students completed a
questionnaire which examines the online learning experiences of these
learners. The survey assessed learners’ self-efficacy for completing an
online course, interactions with content, instructor, other students, and
overall satisfaction. The paper examines whether moving to entirely online
learning during the pandemic has affected their life and study positively or
negatively.
The mediating effects of teacher-student power relations in a blended
English course for academic purposes
Authors: Cheng Li
Published: December 2021

Guided by the theory of Language Socialization (LS), this study
investigates the mediating effects of teacher-student power relations in an
academic English course. To do so, several sets of data were collected:
responses to a questionnaire survey, a series of semi-structured interviews,
and the online interactions which took place on two teaching platforms
(WeChat and QQ). Our results show that together with other factors, the
power relations highlighted in this study influenced the participants’
academic performances. Besides, three types of teacher-student power
relations were brought to the fore. Eventually, the power relations
identified affected the construction of role identity in our study. The
findings provide supporting evidence for the complicated power relations
which exist between language learners and their community of
practice.
EFL learners and English email writing: developing a computerised
diagnostic language assessment
Authors: Nicholas Allan , Blake John , Mozgovoy Maxim
Published: December 2021

Email remains a key mode of communication between faculty and students
in higher education institutions. Composing appropriate email texts is an
important skill for learners; however, little technological support is
available for the pragmatic aspect of email communication – the ways in
which social context influences language choices. Furthermore, pragmatics
can be undertaught in the language classroom. One approach to providing
support for learners while also addressing the issue of giving instruction
to large class sizes is via computerisation. In this ongoing research
project, we describe the development of a Computerised Diagnostic Language
Assessment (C-DLA) of L2 English email writing for Japanese English as a
Foreign Language (EFL) learners in Japanese higher education. The C-DLA
provides automated feedback to learners on the pragmatic aspects of their
draft email texts, with feedback adapting to learners’ success in resolving
identified issues. We report on the development phases of the project,
challenges encountered, and implications for further research.
Assessing learners’ needs for practising spoken Icelandic L2 with the
mobile app TALAÐU!
Authors: Sissoko Fanny , Bédi Branislav
Published: December 2021

This article presents results from a human-centred approach study to
designing a mobile app TALAÐU!, which aims at assisting learners of
Icelandic as a second language (L2) with spoken language practice. The main
goal of the app would be to encourage learners to have real-life
conversations with Icelandic speakers by accomplishing conversational
missions. In the first stage of development, a qualitative deep-method needs
study in the form of interviews was conducted with 19 migrants from 14
different countries, who permanently live in Iceland. Results indicated that
learners have five core needs for practising spoken language: connection,
confidence, clarity, growth, and convenience. Based on different learning
styles and confidence in speaking rather than language ability, three main
learner profiles were indicated: ‘diving in’, ‘learning with caution’ and
‘dipping a toe’. Both the learners’ needs and the profiles would drive the
design of the learning app to personalise and maximise the learner
experience with practising spoken L2. This human-centred study approach
suggests an innovative strategy in designing a learning app for practising
L2 in a specific language and culture environment.
Students’ intercultural sensitivity development through telecollaborative
Chinese language learning on Zoom: a case study of Irish students at the
beginning-level of Chinese language
Authors: Wang Mengdi , Devitt Ann , Hodgins Garreth , Bauer Ciarán
Published: December 2021

This descriptive study presents the first research cycle with four
synchronous telecollaborative language learning sessions on Zoom between
Irish and Chinese teenagers. Intercultural Sensitivity Scale (ISS)
post-questionnaire results show that the mean of interaction enjoyment scale
is the highest compared to the other four categories, which implies that
telecollaboration provides an enjoyable and authentic environment for Irish
adolescent learners to experience communication with native speakers.
However, low averages of ISS categories indicate some factors are at play
such as short telecollaboration duration and potential technological issues.
The gap between the previous needs analysis and current findings
demonstrates that participants probably underestimated the challenge of
engaging with Chinese native speakers, which would suggest that more
scaffoldings and preparations are required for beginning-level learners
before and during telecollaborations.
Less commonly taught languages at EUROCALL: what has changed over the
years?
Authors: Ward Monica
Published: December 2021

The world of Computer Assisted Language Learning (CALL) is dominated by
English, and to a lesser extent, French, Spanish, and German. While these
languages are the main focus of EUROCALL conferences, there has always been
a presence of Less Commonly Taught Languages (LCTLs) at these conferences.
Most of the official languages of the EU and European languages more
generally have been discussed by CALL researchers at EUROCALL conferences,
but some languages have yet to make an appearance. There have also been
presentations on other LCLTs outside of Europe, including Mandarin, Arabic,
Japanese, and less widely spoken languages such as Thai and Nahuatl. This
paper looks at the presence of LCTLs at EUROCALL conferences since 1993 and
reflects on what has changed over the years. It notes the importance of the
conference location on the languages discussed at the conference and the
role of EU projects in supporting LCTLs.
Developing pedagogically appropriate language corpora through
crowdsourcing and gamification

Published: December 2021

Despite the unquestionable academic interest on corpus-based approaches
to language education, the use of corpora by teachers in their everyday
practice is still not very widespread. One way to promote usage of corpora
in language teaching is by making pedagogically appropriate corpora,
labelled with different types of problems (for instance, sensitive content,
offensive language, structural problems), so that teachers can select
authentic examples according to their needs. Because manually labelling
corpora is extremely time-consuming, we propose to use crowdsourcing for
this task. After a first exploratory phase, we are currently developing a
multimode, multilanguage game in which players first identify problematic
sentences and then classify them.
