Published: August 2023

Corrigir a relação molar de Classe II em um paciente adulto não é uma tarefa fácil. E com os alinhadores ortodônticos isso torna-se ainda mais difícil. Os alinhadores têm dificuldade na sua correção, principalmente porque sua eficácia depende do uso de elásticos e, muitas vezes, os pacientes não colaboram o suficiente. Há casos em que o paciente deveria ser tratado com cirurgia ortognática, mas o paciente não aceita ser submetido a ela. Então, podemos tratá- -lo de forma compensatória utilizando um propulsor mandibular, como o PowerScope. Este artigo descreve três maneiras de incorporar o PowerScope no tratamento da Classe II com o Invisalign. São descritos os desenhos híbrido, simplificado e complexo, cada um ilustrado por um caso clínico. Desta forma, pode-se concluir que o PowerScope pode ser um grande aliado no tratamento de casos complexos de Classe II junto aos alinhadores Invisalign. A abordagem é muito promissora, mas ainda necessita de alguns ajustes.

A utilização de alinhadores no tratamento ortodôntico é uma realidade cada vez mais presente na rotina do ortodontista, especialmente em pacientes adultos que buscam alternativas mais confortáveis e estéticas para os aparelhos fixos convencionais. O tratamento da Classe II com alinhadores representa um grande desafio na Ortodontia atual, uma vez que o planejamento do caso, os princípios mecânicos empregados e os resultados esperados podem variar em relação às mecânicas tradicionais. Considerando a importância e a recorrência do tema na atualidade, o objetivo deste artigo foi relatar o caso de uma paciente adulta com má oclusão de Classe II tratada com a distalização sequencial dos dentes superiores utilizando alinhadores Invisalign, bem como discutir a prescrição utilizada e os resultados do tratamento, esclarecendo os ortodontistas sobre as potenciais vantagens e desvantagens desta modalidade de tratamento.
Deficiências biomecânicas dos alinhadores – dentes posteriores
Authors: Ursi Weber José da Silva , Matias Murilo
Published: August 2023

Nos últimos anos, um número crescente de pacientes adultos tem procurado tratamento ortodôntico e expressado o desejo de alternativas estéticas e confortáveis aos aparelhos fixos convencionais. A possibilidade de usar aparelhos ortodônticos transparentes foi introduzida em 1946, quando Kesling desenvolveu o conceito de usar uma série de posicionadores termoplásticos para mover progressivamente os dentes desalinhados para as posições corretas. Contudo, as deficiências biomecânicas próprias dos alinhadores levaram a se desenvolver, além de planejamentos digitais customizados e inteligentes, ferramentas auxiliares, como attachments otimizados, ancoragem esquelética e tratamentos híbridos combinados com aparelhos fixos com arco contínuo ou segmentado, os quais podem ser incorporados antes, durante ou após o uso dos alinhadores, permitindo que os objetivos ideais pretendidos sejam alcançados. Para ilustrar, apresentamos um caso clínico de segundos molares superiores posicionados em mordida cruzada, torque lingual de coroa e giroversão para mesial, corrigidos com mecânica segmentada, utilizando fios retangulares de TMA com alças em “T” para obtenção de um melhor controle tridimensional do movimento.

Published: August 2023

A decisão pela extração de dentes permanentes para a solução de problemas ortodônticos considera, além da extração em si, outros fatores, dentre eles, as características clínicas do esmalte dos dentes a serem extraídos. O objetivo deste artigo foi apresentar como a presença de defeitos de esmalte dentário (DDE) influenciou na tomada de decisão e modificou o plano de tratamento ortodôntico proposto para o paciente. A severidade do defeito, o número de dentes afetados e a presença e complexidade de má oclusão são fatores que influenciaram na definição do plano de tratamento. Quanto mais grave os defeitos e mais complexa a má oclusão, maior a dificuldade no planejamento do tratamento e, em muitos casos, é indicado incorporar a contribuição de vários especialistas na tomada de decisões. Foi possível demonstrar que o tratamento da má oclusão associada a DDE com a exodontia dos dentes mais severamente afetados apresentou resultados estético e funcional adequados. Concluiu-se que um tratamento bem-sucedido da má oclusão com resultado estético dentofacial adequado, saudável e funcional, requer a compreensão da inter-relação entre os componentes estruturais bucais, oclusão dentária e estética facial.

A segunda mais prevalente má oclusão de Angle na população é a de Classe II. Dentre as abordagens de tratamento consideradas pelos profissionais, está a distalização dos dentes posteriores superiores ou exodontias. A distalização, dependendo do nível de complexidade do caso, pode ser desafiadora e necessitar de mecânicas auxiliares para realizar movimentos translacionais e não somente de inclinação coronária. A escolha da abordagem para esses tratamentos depende diretamente da colaboração do paciente, severidade da má oclusão, caracterização da Classe II, idade do paciente e habilidade técnica do profissional responsável. Com o aumento da procura por tratamentos ortodônticos mais estéticos, os alinhadores ortodônticos têm sido frequentemente uma alternativa aos pacientes. Dependendo da severidade da má oclusão, pode-se associar aos auxiliares comumente utilizados na Ortodontia convencional fixa. Portanto, o objetivo deste trabalho é apresentar a resolução de uma má oclusão de Classe II, divisão 1, com impactação do canino superior direito e desvio de linha média superior para a direita tratada com alinhadores ortodônticos ClearCorrect.

O propósito deste estudo foi comparar a magnitude de torque de fios retangulares de níquel titânio (NiTi) estéticos e convencionais submetidos aos testes de torção. Foram testados fios comerciais de NiTi pré-contornados estéticos e convencionais de 4 marcas comerciais (American Orthodontics, Eurodonto, Orthometric e TP Orthodontics) de secção transversal 0.016” x 0.022”. Os testes foram realizados em máquina de torção com rotação de 0° a 90° e foi analisado o comportamento na desativação em 20° e no torque máximo a 90°. Aos 20° no descarregamento, os fios estéticos e convencionais da American Orthodontics tiveram maior expressão de torque, enquanto os fios da Eurodonto convencional e TP Orthodontics estético apresentaram menor torque. No torque máximo a 90°, os fios que tiveram maior expressão foram da TP Orthodontics convencional e American Orthodontics estético, e os fios de menor torque foram da Eurodonto convencional e Orthometric estético. Não foram encontradas diferenças estatisticamente significativas quando os fios estéticos foram comparados entre si. Ao comparar fios estéticos e convencionais de mesma marca comercial, a única que apresentou diferença estatisticamente significativa foi a Eurodonto. Concluiu-se que, quando comparados os torques dos fios estéticos e convencionais de mesma marca, não foram encontradas diferenças estatisticamente significativas, exceto o da marca Eurodonto, que apresentou menor torque para os fios convencionais.

Published: August 2023

Atualmente temos pacientes mais preocupados com a estética facial, e essa tem sido o principal motivo para a procura do tratamento ortodôntico, sendo a linha média facial um fator importante na análise morfológica do sorriso do ponto de vista estético. O desvio da linha média dentária atinge o complexo dentoalveolar, e ocorre quando existe um desequilíbrio entre os dentes e a base apical, do hemiarco direito e esquerdo ou entre os dentes superiores e os inferiores. A utilização de microparafusos como unidades de ancoragem, além de anular os efeitos colaterais indesejáveis, simplifica a mecânica ortodôntica, fornece uma maior previsibilidade ao resultado do tratamento, proporciona maior conforto e estética ao paciente, reduz o tempo de tratamento e possibilita a correção de casos com perdas dentárias, já que fornece uma ancoragem direta. O objetivo principal deste trabalho foi demonstrar através de um relato de caso clínico a correção da assimetria de desvio da linha média e uma melhor harmonia facial com a utilização de exodontias assimétricas de pré-molares e o uso de microparafusos ortodônticos de titânio como ancoragem
Applying the Bayesian Technique in Designing a Single Sampling Plan
Authors: Kadir Dler H. , Rahi Abdul Rahim K.
Published: August 2023

The Bayesian sampling plans for production inspection are considered a technique of sampling inspection techniques for determining the characteristics of the sampling plan based on the assumption that the rate of defectives is a random variable that varies from one production batch to the next, resulting in a probability distribution f(p) that could be determined based on experience and the available quality information available. As part of this study, the parameters of a single Bayesian sampling plan (n,c) were derived by using the Beta-Binomial distribution and compared with those of other single sampling plans. Researchers have identified (ALA company for soft drinks), which handles product quality control. 120 production batches were selected, and the size of the batch and the number of defective items were used to determine the proportion of defective items, given that the variable varies randomly from one production batch to the next. Bayesian and decision-making models can be implemented to create a single sampling inspection process that is close to the actual quality level. The researchers discovered that when the decision-making model was used, the sample size was minimal compared to other inspection plans, leading to a low inspection cost.
A Sociopragmatic Study of the Strategies of Ostensible Invitations in Saudi Arabic
Authors: Ashoor Dhaifallah Alzahrani Shorouq
Published: August 2023

The current study investigated the speech act of ostensible invitations in Saudi Arabic from a sociopragmatic perspective. It was conducted to examine whether Saudi Arabic speakers draw on the same strategies stipulated by Clark and Isaacs (1990) for extending ostensible invitations. Additionally, the study aimed at investigating whether there are Saudi-specific strategies for extending ostensible invitations. To this end, the study examined 37 recalled instances of ostensible invitations provided by Saudi Arabic speakers in the Central Region of Saudi Arabia, Riyadh. The corpus of the study was compiled through face-to-face and written interviews with 37 informants aged between 18 to 60. The collected data was analyzed on the basis of Clark and Isaacs’s seven strategies for establishing ostensible invitations. Results showed that Saudi Arabic speakers utilize the seven strategies proposed by Clark and Isaacs for extending ostensible invitations, yet with relative weight. The most frequently used strategies by Saudi Arabic speakers to issue ostensible invitations in the collected exchanges were the absence of persistence, which was detected in (86%) of the exchanges, and the absence of motivating the invitee, which was used in (73%) of the collected ostensible invitations. Those were followed in order of frequency by vague arrangements (59%), implausibility (49%), inappropriate cues (19%), solicitation (14%), and hedging (5%). In addition to Clark and Isaacs’s proposed strategies, the study found that three more strategies are employed by Saudi Arabic speakers to highlight the ostensibility of their invitations which are: using intensifying and empty swearing devices (e.g., d̪ˁaroori, laazem, wallah, etc.) (27%), extending the invitation in the form of a question (5%), and asking someone else to extend the invitation on behalf of the inviter (5%), the last of which seems to be peculiar to Saudi Arabic speakers.

Abstract in English

It is important to determine the presence of different radionuclides in the environment at all times in order to control and assess the risk level they pose to the environment. Laboratory and in-situ gamma-ray spectrometry can be used for detecting, monitoring, and assessing levels of radioactivity and radiation dose rates in the environment due to both natural and artificial sources. In this study, the greatest challenge in the calibration of detectors for in-situ gamma spectrometry has been solved. Calibration factors that can be used to convert the net count rates of collected spectrum's photopeak using a portable gamma-ray spectrometer, to quantitative specific activities have been derived. Calibration pads were simulated using standard materials RGU, RGK, and RGTh from International Atomic Energy Agency (IAEA). Region of interest (ROI) were carefully determined around these photopeaks in order to obtain count rates due to each radionuclide under its reference peak. The conversion factors obtained are reliable.

Authors: Abdumajidov Khamidulla , Buranov Khairulla
Published: August 2023

Objective: We present a rare case of surgical management of giant myxoma of the right heart with obstruction of the orifice of the inferior vena cava (IVC), obstruction of the right atrioventricular orifice, with the development of high pulmonary hypertension, and severe heart failure.

Case presentation: A 39 years old male patients applied to the consultative polyclinic with typical complaints of severe shortness of breath, palpitations, severe weakness, almost bed rest, severe swelling of the lower extremities, with a transition to the anterior abdominal wall (edema). On physical examination signs of severe heart failure NYHA class IV were revealed. Imaging demonstrated giant right atrial myxoma obstructing IVC with base originated in fossa ovalis, obstructing tricuspid valve and protruding in the right ventricle occupying 50% of its cavity.  The surgical removal of the giant RA myxoma protruding the right ventricle and obstructing IVC and tricuspid valve was performed under cardiopulmonary bypass and hemodynamic support. The patient was discharged on the 10th day after surgery and only residual minimal tricuspid regurgitation was revealed on follow-up examination. 

Conclusion: The described case from our practice proves the possibility of a severe course of giant myxomas of the right heart, with the development of deep hemodynamic complications of systemic and pulmonary circulation. The chosen correct tactics of surgical treatment provided a favorable result, despite the severity of the initial condition and the degree of hemodynamic disturbance. Intraoperative tactics and technique for performing the stages of urgent surgery were chosen based on the situation, the features of the anatomical structure of the tumor, and the severe complications that arose. Our case proves the possibility of adequate implementation of such interventions, when choosing the right tactics of surgical treatment.

Take home message: If clinical signs of circulatory failure, heart failure are detected, it is necessary to perform echocardiography. If mass formations of the heart chambers are detected, immediately refer the patient to specialized cardiac surgery clinics to resolve the issue of surgical correction of pathology.

Cofferdam is a building in the form of earth, stone, concrete or masonry filling and holds water, prevents flooding, provides irrigation. The building has many functions such as for agriculture, power generation, and tourist attractions. Cofferdam will also be very helpful in flood control which will control flood water so that it will not overflow excessively which endangers the surrounding community. Besides having great benefits. If the cofferdam collapses (broken) it will cause flash floods that result in casualties. Therefore the cofferdam must be designed safely and technically feasible. The research approach used in this study is a quantitative approach using the 2012 GEO-SLOPE program. The conclusions from the analysis of slope seepage and seepage stability are the Critical Safety Factors for cofferdam stability according to the results of the analysis after running SLOPE/W are 1.711 & 1.512 because it is higher than 1.5 (SNI 8460:2017 Geotechnical Requirements Design, This means that the stability of the cofferdam is safe. The modeling results show that the seepage discharge is 1.81x10-7 m3/s = 1.81x10-4 liters/sec = 15.64 liters/day which is smaller than the maximum allowable discharge of 50 liters/day. So it can be concluded that the seepage discharge is safe.

This study aims to determine the anxiety-related coping strategies used by the general population in Indonesia during the COVID-19 pandemic. A cross-sectional study was conducted online in 34 Indonesian provinces on May 2–4, 2020, during the COVID-19 pandemic. A total of 2189 respondents aged 15-year-olds and older participated in this study. The Lime survey application platform and social media distributed the questionnaires. Multiple multinomial logistic analysis was performed to calculate the adjusted odds ratio (aOR) of coping activities with anxiety levels after adjusting for age, sex, marital status, education, occupation, and homeownership. Moderate and severe anxiety was more experienced by respondents aged 15–24 years, were female, not/unmarried, had middle-high education, were getting layoff, and lived in an employer-provided residence. Spiritual activity (aOR = 0.30; 95% CI [0.10, 0.87]; p = .027), physical activities (aOR = 0.28; 95% CI [0.16, 0.50]; p < .001), and leisure activities (aOR = 0.25; 95% CI [0.14, 0.46]; p < .001) provided the best protection against severe anxiety. In contrast, those who smoked cigarettes and consumed alcohol were more likely to experience mild-to-severe anxiety (aOR = 2.77; 95% CI [1.1, 6.64]; p = .022). Interestingly, those who shared their problems with others were more likely to experience mild anxiety (OR = 1.98; 95% CI [1.52, 2.58]; p < .001). Spiritual, physical, and leisure activities are expected to be associated with mild, moderate, and severe anxiety. Promoting physical, leisure, and spiritual activities plays a vital role in the community as a coping strategy for stressful times, especially during pandemics.

The public transport sector in Nigeria has often been stereotyped as male-dominated. Over the years, the upsurge in the unemployment rate and the necessity of economic empowerment have pushed women to adopt commercial tricycle riding as a livelihood. This article explores the perception of women as tricycle riders by passengers and commuters in Ikeja, Lagos State, southwestern Nigeria. The study is anchored on the social role theory, which argues that gender stereotype is a product of the gendered division of labor that assigns social roles to men and women based on culturally approved norms and standards. Data for the study were sourced through qualitative ethnographic approaches involving focus groups and semi-structured interviews with thirty participants (N = 30) who were purposively sampled. The authors argue that even though women are rising to the moment regarding competence and performance standards as tricycle riders, gender stereotypes constrain their acceptance and patronage in the business. We further demonstrate that unfavorable career evaluations promote bias against female tricycle riders. In this way, gender discrimination is deeply entrenched in the public transport sector in Nigeria. The study advocates for a more inclusive career culture and practices where men and women can feel valued and earn a living without discrimination and marginalization.
