Objective: This study aimed to produce formula age determination by the root length of mandibular third molar on panoramic radiograph in Deutero Malay subject.
Material and Methods: The analytical study design was done with 130 mandibular third molars on 90 panoramic radiographs of the Deutero Malay subject from patients who visited the Oral and Maxillofacial Radiology Unit at Dental Hospital Universitas Padjadjaran, Bandung, Indonesia. The inclusion criteria were patients in the age range between 15 to 21 years, panoramic radiograph with good quality, and the root of the mandibular third molar is still developing. The panoramic radiograph with the teeth showed root anomaly, dental pathology, and malposition as bucco-linguoangular were excluded. The root length of the third molar was measured from CEJ – root apex in millimeters following by Thevissen's modified scoring method using Fiji ImageJ-Win64. The simple linear regression of statistical IBM software was used to analyze the result. The reliability of the observers was evaluated to know the observer's variability.
Results: There was a very strong correlation between the root length of mandibular third molar and chronological age for male (R=0.949) with formula chronological age = 11,847 + 0,459 (Root Length), (R2=0.901), (SEE=0.692), and for female (R=0.946) with formula chronological age = 13,701 + 0,410 (Root Length), (R2=0.895), (SEE=0.622).
Conclusion: The root length of the mandibular third molar on a panoramic radiograph can be used for age determination in Deutero Malay subjects.

Incorrect management of a broken abutment screw
Authors: Boffano Paolo , Ruga Emanuele , Anna M. Agnone  , Vincenzo Rocchetti
Published: April 2024

Implant abutment screw fracture is an uncommon though challenging complication. A fractured abutment screw should be removed without damaging the threads of the screw channel to reuse the prosthesis.

To retrieve the fractured part without severing the threads, various procedures have been proposed, such as to try to unscrew the fractured part using a strong, straight and pointed probe, or to prepare a small dent into the center of the fractured part using a small round diamond burr or a fissure burr in a counter clockwise motion. Various screw removal kits have been introduced to this aim, but with inconsistent results. 

When a physician does not manage to remove the fractured screw in either way, he/she often chooses to either replace the implant, which can be an expensive option, or abandon the implant and cover it with soft tissue, which may lead to compromised function, phonetics, or esthetics. Instead, saving the implant would great benefit patients. To this aim, the conversion of the screw chamber into a dowel space for a dowel-core and crown restoration has been proposed, thanks to the aid of laser-welded titanium for example. Instead, other techniques do not seem to have been commonly accepted.

The aim of the present article is to present the incorrect management of a fractured abutment screw by a classic surtex post.

Published: April 2024

Objective: This case report aimed to describe a case of a post-core-crown restoration in an anterior tooth that had been endodontically treated with a direct monobloc technique using a composite resin material. Methods: After root canal treatment on tooth 11, a post cavity was made in the root canal with a diameter of 1 mm and a length of 5 mm. The post cavity was then filled with dual-cure resin cement and light-polymerized. Next, the core build-up is carried out using the same material, and crown preparation is carried out with a circumferential chamfer margin. The crown was made with direct composite resin materials with the aid of a silicone key to create a palatal enamel wall and then proceeded with the bilaminar technique until the crown was finished. Results: Three months' follow-up showed that the restoration was still in good condition and could function optimally. Conclusion: Post-core-crown restoration using direct monoblock technique using composite resin material shows good results and is aesthetically acceptable after three months of follow-up.

Authors: I-Komang E. Wijaksana  , Shafira K. Supandi
Published: April 2024

Objective: The objective of this article is to present fibrin-assisted soft tissue promotion (FASTP), a simple root coverage surgical procedure associated with the use of A-PRF as a source of autogenous growth factors that allow the recipient soft tissue to promote the fabrication of new keratinized and attached tissue without a donor site.
Methods: The case of a 20-year-old non-smoker female patient was reported to the Universitas Airlangga Dental Hospital with a chief complaint of tooth hypersensitivity to cold stimuli at the posterior right maxilla and mandibular. A 1–1,5 mm gingival recession was found on the buccal aspect of 14, 15, 44, and 46. A final diagnosis of clinically healthy gingiva on reduced periodontium in a non-periodontitis patient was made. The treatment plan included dental health education with a focus on brushing methods and scaling procedures that were performed as non-surgical therapy. A FASTP procedure was planned for root coverage treatment on the buccal aspect of 14, 15, 44, and 46.
Results: A 1-year evaluation was done and showed complete root coverage with an acceptable gingival phenotype.
Conclusion: FASTP is a simple root coverage surgical technique without the need to harvest tissue from a donor site, thereby decreasing procedure-related morbidity. Case selection plays an important role in proper surgical technique consideration.

Published: April 2024

Objective: This study aims to assess dental students’ preparedness for infection control, and willingness to treat patients with or potentially transmit diseases.
Material and Methods: The cross-sectional study was conducted on 121 dental students from the Faculty of Dentistry Universitas Syiah Kuala in 2019. The questionnaire used in previous study in 2017 and consisted of demographic data, preparedness for infection control, and willingness to treat patients with infectious diseases.
Results: There were 121 dental students, the majority are female with one year experience of clinical experience. For infection control preparedness, majority of respondents already do personal protective equipment (64.5%), sterilize instrument before use (74.4%), but for the willingness respondents prefer not to treat patient with transmitted diseases such ad patients with tuberculosis (19.8%), people living with HIV/AIDS (19.8%), Hepatitis C (11.6)  and also patient who potentially transmit infection such as sex workers (19.0%) , injecting drug users (19.8%)  and LGBT (14%). prefer not to treat patients who potentially transmit infection. Result of the Spearman correlation test, showing infection control has no such correlation with willingness (r <0.15) .
Conclusion:  The practice of applying universal precautions has been carried out by respondents, but the levels of students’ willingness to treat patient with infectious disease still very low. It’s necessary to carry out continuing education regarding safety training, so that it can enable dental student to work safely and no longer discriminate against patients.

Formulating problems in psycho-social rehabilitation
Authors: Piccini Chiara , Carassa Antonella
Published: April 2024

This article presents a study on team talk in psychosocial rehabilitation with reference to collective decision making. It focuses on problem formulation processes that occur during weekly team meetings in a Swiss organization providing psychosocial rehabilitation to chronic mental health patients.
The corpus of team meetings (34 hours of recorded talk) was analyzed along three narrative dimensions: participation framework, timeline organization and forms of evaluation. The analysis was supported by ethnographic information (field notes collected during participant observation over ten months), in order to access the local conception and organization of rehabilitation work, which is repeatedly referred to and reshaped through discourse.
The discursive practices identified show that team members learn to formulate problems in a way that allows them to identify and plan interventions in line with their rehabilitation model and the actual opportunities they have. Further, the role-related forms of participation highlight how different professionals contribute to the problem formulation in specific ways.
In sum, the interaction turns out to be strongly centralized around the role of a meeting coordinator, who is able to enhance the participation of the other team members and to build institutional narratives on the basis of individual contributions, carrying out discursive work that can be metaphorically described as the weaving and knotting threads that make up a tapestry.
The patient or lay person as expert
Authors: Wynn Rolf
Published: April 2024

In the interview, Sarangi rightly points to the increasing drive to recognize patients, and more generally, lay persons, as experts and decision-makers. For instance, patients have their own unique knowledge of being a patient and receiver of healthcare services. A patient also knows what is important to him or her and must therefore play a crucial role in the decision-making process relating to the care given.
Association study of NAT2 rs1799931 polymorphism with male infertility
Authors: Thanh Thuy Nguyen , Tien Duc Pham , Huu Dinh Tran , Thuy Duong Nguyen
Published: April 2024

Infertility is a complex disease that is characterized by the failure to achieve pregnancy after 24 months of regular, unprotected sexual intercourse. Various factors result in male sterility, including genetic and non-genetic factors. Recently, scientists have drawn attention to the role of metabolic genes in contributing to the risk of male infertility by inducing reactive oxygen species (ROS). However, such studies about N-acetyltransferase 2 (NAT2), an enzyme that participates in phase II metabolism, remain limited. Thus, this study investigated whether the NAT2 rs1799931 variant was associated with idiopathic male sterility in Vietnam. A total of 306 DNA samples (148 cases and 158 controls) were genotyped using the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods. About 20% of randomly selected samples were confirmed using an allele-specific polymerase chain reaction (AS-PCR). The results showed that genotype frequencies were consistent with Hardy-Weinberg Equilibrium. Notably, there was an association between NAT2 rs1799931 and male infertility in two genetic models: the additive model (GA genotype, OR = 0.606, 95% CI: 0.369–0.989, p-value = 0.044) and the dominant model (GA+AA genotypes, OR = 0.614, 95% CI: 0.382–0.981, p-value = 0.040). This study has enriched our knowledge about the roles of genetic factors in contributing to male infertility in the Vietnamese population.

Associations between tree spacing and features of native grassland grown in silvopastoral systems in Pampa biome
Authors: Tonini Helio , Genro Teresa Cristina Moraes , Trentin Gustavo
Published: April 2024

ABSTRACT: The current study assessed the association of eucalyptus-tree spacing with forest growth and yield, as well as with the floristic composition, diversity and yield of natural grassland grown in silvopastoral systems in Pampa biome. Data were collected in six family cattle-ranching area in Bagé County (RS). The effect of two different genetic materials (seminal-origin Eucalyptus dunnii plant and one Eucalyptus grandis clone) on shading features of plants grown in 3 planting-spacing dimensions(625, 312 and 208 trees ha-1) was assessed, as well as their association with herbaceous extract (bare soil; green cover; forage dry matter; floristic composition; species richness; and grass, legumes and winter - and summer-growth species rates) and forestry (litter accumulation, diameter at breast height, total height and volume per hectare) variables. Planting carried out at the highest tree density (625 trees ha-1) has increased forest yield. However, it reduced green cover, herbaceous extract dry-matter yield and species richness, mainly in grasses and legumeswith greater forage potential. Conversely, it is possible combining forestry and animal yield to the preservation of native forage species at low tree densities (204 to 312 trees ha-1).

Abstract Rendu-Osler-Weber syndrome, also known as hereditary hemorrhagic telangiectasia, is an autosomal dominant hereditary disorder. It is characterized by presence of multiple arteriovenous malformations (AVMs) and telangiectasias. This article reports two cases of patients with Rendu-Osler-Weber syndrome who had pulmonary AVMs and underwent successful endovascular treatment. A brief review of the literature shows that up to 50% of patients with the syndrome have pulmonary AVMs and there is usually a positive family history in these patients. These pulmonary AVMs are multiple in 30% of cases and are associated with the most severe disease complications. Most patients are asymptomatic, even in the presence of AVMs with right-left shunts. When these shunts exceed 25% of the total blood volume, dyspnea, cyanosis, digital clubbing, and extracardiac murmurs may occur. Endovascular treatment is safe and offers control of complications from hereditary hemorrhagic telangiectasia and is currently the treatment of choice for these lesions.
Population biology of Cymadusa filosa (Crustacea: Amphipoda) associated with Sargassum furcatum (Phaeophyceae) beds in a coastal area of Brazil with petrogenic hydrocarbon pollution

Published: April 2024

ABSTRACT This study aimed to assess population and reproductive aspects of the ampithoid amphipod Cymadusa filosa Savigny, 1816 in a region with pollution by petrogenic hydrocarbons. Sampling of Sargassum furcatum Kützing, 1843 fronds and the associated fauna was conducted in March, September and December 2007 and February 2008, on four rocky shores located on São Sebastião Island, southeastern Brazil. A total of 1372 specimens of C. filosa were recorded, including 934 juveniles, 274 females (60 ovigerous) and 164 males. Population mean density ranged from 1.27 to 6.40 ind/g with higher mean values in March 2007 and lower in December 2007 and February 2008. The total body length of males varied from 4.11 to 20.75 mm and of females from 3.58 to 20.22 mm. No significant difference was detected between male and female body length. The overall sex ratio significantly differed from 1:1 proportion and was skewed toward females (0.60:1). Ovigerous females occurred in higher proportion in February 2008 and presented mean fecundity of 26.01 ± 1.84 eggs/female (mean ± se), with great variation in the number of eggs found in the marsupium (between 1 and 56). Fecundity increased significantly with increasing female body length. The C. filosa population structure and reproduction were similar to those of populations in other locations, in Brazil and abroad indicating that pollution by petrogenic hydrocarbons in the São Sebastião Channel did not affect the population parameters of C. filosa in this region.

Published: April 2024

Abstract Objectives: to evaluate the effect of oropharyngeal colostrum immunotherapy on the length of hospital stay in preterm newborns with very low birth weight. Methods: interventional ambispective study, which consisted of eight daily administrations of 0.2 ml (four drops) of colostrum, totaling up to 56 syringes (for up to seven days). The control was historic. The main independent variable: length of hospital stay (days). Survival analysis was performed using the Kaplan-Meier Method and the survival effect was estimated - Log Rank Test (Mantel-Cox) and Breslow Test (Generalized Wilcoxon). A significance level of 5% was adopted. Results: of the 109 mother/child pairs, 56 were part of the treatment and 53 were part of the control group. There was no association between oropharyngeal colostrum immunotherapy and length of stay for preterm newborns with very low birth weight in the general sample. However, after stratification, a shorter hospital stay (42 versus 51 days, HR= 1.78, CI95%=1.02-3.09, p=0.04) was demonstrated among premature infants with ≥28 gestational weeks undergoing oropharyngeal colostrum immunotherapy. Conclusions: we found an association between oropharyngeal colostrum immunotherapy and shorter median length of hospital stay in the subgroup of premature infants ≥ 28 weeks of gestational age, but we did not find significant differences in those <28 weeks.
Heterogeneous regional effects of rural credit on agricultural production in Brazil
Authors: Sobreira Diogo Brito , Tabosa Francisco José Silva , Costa Edward Martins , Khan Ahmad Saeed
Published: April 2024

Abstract Access to rural credit has been persistently heterogeneous across Brazilian regions over time. This work aimed to estimate the regional effects of rural credit on agricultural production due to the heterogeneity observed in access to credit. Based on data from the 2017 Agricultural Census and climate variables, the effect of rural credit was estimated by standard regressions, combined with the entropy balancing technique. The results show positive and significant effects of rural credit on Brazilian agricultural production, even after controlling for observed covariates. This result was consistent even after balancing the covariates with regard to entropy. The effect of rural credit proved to be heterogeneous across Brazilian regions, being positive and significant for regions with greater access to rural credit and statistically null in less credit-intensive regions. Furthermore, estimates show that technical assistance is an important transmission mechanism of the rural credit effect.

Published: April 2024

ABSTRACT Objective: to analyze high-risk parturient women’s experiences with the use of non-invasive nursing care technologies during labor. Method: this is qualitative and descriptive research, with twenty high-risk postpartum women admitted to a tertiary maternity hospital in the state of Rio de Janeiro, Brazil. Data were collected from April to July 2019 through semi-structured interviews, subjected to thematic content analysis and analyzed in light of Kristen Swanson’s Theory of Caring. Results: the experiments revealed that theory processes were associated with the use of non-invasive care technologies by nurses. “Maintaining belief”, “knowing” and “being with” were made up of the following technologies: encouraging self-confidence; understanding the lived experience; bond formation; and creating a supportive and helpful relationship with parturient women. The “doing for” and “enabling” processes included other technologies that promoted comfort and facilitated the experience such as: encouraging active participation and conscious breathing; stimulation of vertical positions and pelvic movements; companion involvement in care; using resources, such as warm water, Swiss balls and essential oils; and applying massages. Conclusion: parturient women realize that the use of non-invasive care technologies by nurses shapes experiences of well-being during labor, expressed in feelings of safety, acceptance, respect, appreciation, support and comfort. The importance of investing in nurses’ work in assisting high-risk pregnancies is highlighted, as these technologies provide respectful care and women’s satisfaction with childbirth.

Resumen La enseñanza y el aprendizaje de los números complejos desde la educación matemática se han indagado poco, y las investigaciones que hay al respecto señalan que su tratamiento se hace, comúnmente, desde el registro algebraico. Con la intención de contribuir al estudio de la problemática que se relaciona con ese concepto, en este estudio se realizó desde la teoría APOE una caracterización de las concepciones que han construido sobre los números complejos un grupo de alumnos que inician sus estudios universitarios. Para ello, se diseñó y aplicó un cuestionario que permitió observar las posibles estructuras mentales construidas por los estudiantes. Los resultados indican que los alumnos llegan a la universidad con elementos de las acciones y concepciones acción, pero limitadas, relacionadas principalmente con la representación binómica de los números complejos y en un registro algebraico; asimismo, muestran concepciones previas fundamentales para el estudio de los números complejos, pero desconectadas de ese concepto.
El Método General de Resolución de Ecuaciones en la Arithmetica Universal de José Zaragoza (1669)
Authors: Ruiz-Catalán Jacinto , Madrid María José , Maz-Machado Alexander
Published: April 2024

Resumen En el presente trabajo se estudia el método general de resolución de ecuaciones polinómicas que expuso el matemático valenciano José Zaragoza en su libro Arithmetica Universal, publicado por primera vez en 1669. Este método está basado en el desarrollado por Viète y publicado en su libro De numerosa potestatum, de 1600, y es una evolución del antigüo método babilonio de cálculo de raices. En concreto, este método de resolución se basa en la expansión binomial de las potencias implicadas en la ecuación, detectando dos puntos clave: uno es la selección del número de dígitos de la solución y otro es la selección del divisor adecuado para la estimación de los sucesivos dígitos. El uso de tablas y la explicación detallada de las diferentes ramificaciones del proceso hacen que la configuración empleada por Zaragoza sea muy didáctica, incluso más que la de algunos de los diferentes matemáticos europeos que emplearon este método durante el siglo XVII.
Guía para el análisis de la idoneidad epistémica y cognitiva de lecciones sobre tablas estadísticas en libros de texto
Authors: Pallauta Jocelyn D. , Batanero Carmen
Published: April 2024

Resumen Dado que las tablas estadísticas son ampliamente utilizadas para representar, analizar información y un medio para el estudio de diferentes temas, su enseñanza es considerada en las directrices curriculares de varios países. En este trabajo se presenta una pauta de indicadores de idoneidad epistémica y cognitiva específicos para el análisis de las lecciones sobre tablas estadísticas en libros de texto. Para la elaboración de la guía se utiliza la teoría de la idoneidad didáctica del enfoque ontosemiótico del conocimiento y la instrucción matemática, que entrega elementos teóricos que permiten valorar el proceso de instrucción propuesto en el libro de texto. A través de un análisis de contenido se identifican indicadores de idoneidad epistémica y cognitiva en investigaciones previas, así como en las orientaciones curriculares, de los cuales se seleccionan y categorizan los conocimientos didáctico-matemático sobre las tablas estadísticas en educación primaria y secundaria. La guía aborda las facetas que consideran subcomponentes específicos para el contenido matemático en estudio. De este modo, este instrumento puede servir de apoyo para los profesores en el análisis y valoración de lecciones de libros de texto para el diseño e implementación del proceso de instrucción sobre tablas estadísticas, así como para la formación del profesorado puede ser un recurso que promueva la reflexión.

ABSTRACT Purpose: to assess the influence of wearing a mask on auditory-visual speech recognition, in a favorable listening situation, in hearing devices users. Methods: a cross-sectional observational study comprising 52 hearing aid users, whose speech recognition was assessed with six video-recorded lists of sentences with and without masks. The mean test results in the various situations were compared using the Friedman test with Bonferroni post hoc, the significance level being set at 5%. Results: speech recognition assessment results differed between the situations with and without masks and between mask types, with a small effect size. The post hoc, with p-values adjusted with the Bonferroni method, showed a difference between transparent masks and others. The transparent one had a higher mean (77.8%) of auditory-visual sentence recognition between the various situations. There were statistically significant differences, as the transparent mask provided a better performance than the others. Conclusion: the auditory-visual recognition of the hearing-impaired people was better with the transparent mask.

ABSTRACT Purpose: to analyze the absolute latencies of waves I. III and V and the interpeak intervals I-III. III-V and I-V of the ABR recorded from different age groups of children with congenital zika virus infection and their peers without risk indicators for hearing impairment. Methods: 84 newborns and infants (N=51 study group and N=33 control group) divided into groups with different post-conceptual ages. with the results of their hearing exams analyzed by age group and compared with their peers without other risk indicators for hearing impairment. The assessment of the auditory pathway was conducted through tympanometry. otoacoustic emissions and auditory brain stem responses. Results: only the latency of wave I and the interpeak III-V showed no significant difference between the study and control groups. The absolute latency and interpeak values found in the study group were significantly lower than those found in the control group. Conclusion: the maturation of the brain stem in children with ZIKV infection occurred within normal limits. with no retrocochlear disorders until the age of 5 years.

A Cênica Feminista: teorizações sobre a ciência e a prática da cena teatral feministas e a importância de uma pedagogia feminista no campo teatral
Authors: Romano Lúcia Regina Vieira
Published: April 2024

RESUMO A Cênica Feminista: teorizações sobre a ciência e a prática da cena teatral feministas e a importância de uma pedagogia feminista no campo teatral1 – Este artigo teoriza sobre uma cênica feminista, resultante da aplicação ao teatro das epistemologias feministas, sintetizando a crítica que fazem às demarcações canônicas atreladas ao ato de conhecer, que contribuem para a desvalidação da experiência das mulheres. Associa-se seu modo de funcionamento à consciência das hierarquias de gênero, às quais reage por meio da formulação de estratégias poéticas e políticas de enfrentamento aos modelos sociais discriminatórios e sexistas e aos seus sustentáculos simbólicos. Conclui-se que essa cênica feminista encontra centralidade na pedagogia, onde emergem formas de saber emancipatórias e territórios de resistência e criação, que ressignificam o ser.
The Feminist Scenics: theorizations about science and practice of the feminist theater scene and the space and importance of feminist epistemologies in the theatrical field
Authors: Romano Lúcia Regina Vieira
Published: April 2024

ABSTRACT The Feminist Scenics: theorizations about science and practice of the feminist theater scene and the space and importance of feminist epistemologies in the theatrical field1 – This article describes a feminist scenic, resulting from the application of feminist epistemologies to theater, synthesizing the criticism they make of the canonical demarcations linked to the act of knowing, which contribute to the invalidation of women's experience. Its way of functioning is associated with the awareness of gender hierarchies, to which it reacts through the formulation of poetic and political strategies to confront discriminatory and sexist social models and their symbolic supports. It is concluded that this feminist scenic finds centrality in pedagogy, where emancipatory forms of knowledge and territories of resistance and creation emerge, which give new meaning to being.
