ABSTRACT
Hydroxyapatite could be treated with silver nitrate to produce silver phosphate (Ag3PO4), which is a semiconductor material having ability to degrade synthetic dyes. This research aimed to determine the effect of skipjack tuna fish bone calcination temperature on the characteristics of Ag-modified fish bone products and their ability to degrade the synthetic dye rhodamine B (RB). Skipjack tuna bones were taken from a smoked skipjack fish market in Tanawangko, North Sulawesi. The research was initiated by synthesizing a composite with the main component hydroxyapatite from skipjack tuna (Katsuwonus pelamis L.) bones, which produced Ag3PO4 which was then used to degrade the synthetic dye RB in aqueous solution. The hydroxyapatite and composite were characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy - Energy Dispersive X-Ray (SEM-EDX), and Fourier-Transform Infrared Spectroscopy (FTIR) techniques. These characterizations confirmed the formation of Ag3PO4/HAp composite. Analysis of RB photodegradation activity using the composites showed that the best results of 76% RB degradation were obtained using 100 mg composite made from calcination temperature of 600 oC under 2 x 100 Watts incandescent lamp for 120 minutes.

Published: May 2024

El pensamiento computacional interviene en todos los campos de la sociedad como un eje transversal, lo que lo convierte en un nuevo desafío para la educación centrada en el estudiante y en las habilidades que deben desarrollarse para la vida. Actualmente, el pensamiento computacional se considera una habilidad del siglo XXI que los estudiantes deben tener para desarrollar habilidades de resolución de problemas utilizando los principios informáticos [1]. La informática está presente en todos los aspectos de la vida desde que el despertar por la mañana con un reloj despertador digital durante el día con la administración de aplicaciones, dispositivos móviles y su interacción con el Internet de las cosas, por esta razón es una parte intrínseca de los términos: ciencia, tecnología y sociedad. El pensamiento computacional se fundamenta en la disciplina de la informática y se integra en el conjunto de habilidades y procedimientos mentales y se puede percibir de forma precisa en el aula. Autores en investigaciones concluyen que la inclusión del pensamiento computacional podría darse desde los doce años de edad, pero las clases de computación, deben diferenciarse como la disciplina que facilita el uso de las computadoras aplicadas a tareas específicas en temáticas particulares en el tiempo destinado a la clase. Y aunque existen precedentes en el país con respecto a las propuestas para la capacitación de maestros en el campo tecnológico están orientadas a nivel básico como: el uso del correo electrónico y ofimática básica, desde 2015 no se han impartido cursos de capacitación para maestros de primaria y secundaria en temas de TIC, menos aún en el pensamiento computacional. Este trabajo se basa en una línea de base acerca del pensamiento computacional y una propuesta para su inclusión en el sistema de educación del Ecuador.
El Desempeño Académico como un Comportamiento en el Proceso de Enseñanza Aprendizaje
Authors: Rubiano Romero Sandra Soledad , Martínez Huertas Juan Carlos 
Published: May 2024

El desempeño académico ha sido estudiado en los contextos educativos siempre ligado al rendimiento estudiantil, porque cuando el estudiante presenta bajas calificaciones se expone a diversas situaciones como la pérdida de materias, reprobación del grado escolar y hasta la deserción escolar. Sin embargo, etimológicamente, como señalan Pérez y Merino (2021) el desempeño es reconocido como el acto y la consecuencia de cumplir una obligación, realizar una actividad o dedicarse a una tarea. De allí, que en este artículo se busca profundizar en el concepto de “Desempeño Académico” como un comportamiento; es decir, como las acciones que realiza el estudiante para lograr sus metas académicas, y no como un resultado que lo relaciona con rendimiento estudiantil. El trabajo se fundamenta en los aspectos teóricos de Navarro (2003), Tilano, Henao y Restrepo (2009), Quintero y Vallejo (2013), Erazo (2012), Rendón y Coronel (2019), Enríquez, Segura y Tovar (2013), Duque Vallejo y Rodríguez (2013), Palacios y Vásquez (2003), Reyes et al (2014). Para su realización se hizo una revisión documental, luego mediante una matriz crítica se contrastaron los alcances de cada autor, para posteriormente fundamentar una definición orientada a comprender el desempeño académico como un comportamiento. Los resultados indican que los autores, desarrollan planteamientos canalizados a reconocer el concepto “Desempeño académico”, como resultado del proceso de enseñanza, hasta el punto que algunos lo manejan como sinónimo de rendimiento académico, también se percibe que los autores no tienen un planteamiento claro sobre los componentes del concepto.

Published: May 2024

Aim:
Evaluation of the antibacterial and cytotoxic properties of TotalFill and NeoSEALER Flo bioceramic sealers compared to AH Plus resin sealer.

Materials and Methods:
Modified direct contact test was used on three sets of sealers: Freshly mixed sealers, sealers that were 1-day old, and sealers that were 7-day old. After 24 h of incubation, the colony-forming units were digitally counted using Promega Colony Counter after 30 and 60 min of exposure to Enterococcus faecalis. For cytotoxic effect evaluation, 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide assay was performed at three different time points: 24 h, 48 h, and 120 h after adding the sealer eluates to human gingival fibroblasts, to assess cell viability. Data were analyzed using mixed model analysis of variance followed by post hoc test.

Results:
TotalFill bioceramic sealer showed the highest bacterial reduction against E. faecalis throughout all intervals. AH Plus showed great antibacterial activity initially which reduced drastically after 7 days. All the sealers showed a reduction in their antibacterial activity with time. TotalFill and NeoSEALER Flo showed very high cell viability in contrast to AH Plus.

Conclusion:
TotalFill and NeoSEALER Flo demonstrate superior antimicrobial properties against E. faecalis which reduces with time. TotalFill and NeoSEALER Flo demonstrate acceptable biocompatibility against human gingival fibroblasts, which decreased over time.

Published: May 2024

Background and Objectives:
The present systematic review aims to assess the success rate of the pulp regeneration treatment, according to the American Association of Endodontists (AAE) criteria, using different bioactive materials in permanent teeth of pediatric subjects (6–17 years of age).

Materials and Methods:
The study protocol was registered on PROSPERO and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The question formulation was accomplished using the PICO model, and an electronic search was carried out on Scopus, MEDLINE/PubMed, Web of Science, and Cochrane databases till April 1, 2023. A total of 30 studies were established to fulfill the inclusion criteria of this systematic review.

Results:
A total of 273 teeth have been treated with pulp regeneration treatment. By comparing different biomaterials and the success criteria defined by the AAE, the material associated with a higher success rate was found to be the white mineral trioxide aggregate. However, the overall success rate of pulp regeneration treatment was reported for 248 out of 273 teeth (91.20%).

Conclusions:
Data obtained support the potential that regenerative endodontics aids in continuing root development in permanent immature teeth. Further studies are needed for a more extensive evaluation of the use of different biomaterials and the success rate in regenerative endodontics.

Objective:
The purpose of this study is to comparatively evaluate the effect of discoloration of nanohybrid composite by four different phytopigments.

Materials and Methods:
Fifty disk-shaped samples of nanohybrid (3M Filtek Z350) resin composites were prepared using an acrylic template of dimension 5 mm × 3 mm. They were randomly divided into five groups and immersed in solutions of tomato powder, beetroot powder, java plum powder, and turmeric powder. Distilled water was used as the control group. The samples were placed in respective solutions for 3 h daily and stored in artificial saliva for the rest of the day for 28 days. Color values (L*, a*, b*) were measured by colorimeter using the CIE L*a*b* system at the end of the 7th and 28th days of immersion. Color differences ΔE*ab were statistically analyzed.

Results:
All the samples showed a change in color of nanohybrid composite resin to varying degrees. The mean ΔE*ab value obtained with beetroot solution was the highest among all the groups at the end of the 7th and 28th days, depicting that beetroot solution showed maximum mean color variation, followed by java plum solution, turmeric solution, and tomato solution.

Conclusion:
All the phytopigments used in this study have the potential to discolor the nanohybrid composite resin, with beetroot causing the most severe discoloration.
Comparative evaluation of remineralization potential of novel bioactive agents on eroded enamel lesions: A single-blinded in vitro study
Authors: Behl Mansi , Taneja Sonali , Bhalla Vidhi Kiran 
Published: May 2024

Objective:
The escalating prevalence of noncarious tooth wear stands as a critical concern in the backdrop of evolving lifestyles and dietary patterns. Dental erosion, a progressive condition induced by both endogenous and exogenous acidic influences, directly impacts enamel integrity, resulting in surface loss. The contemporary surge in carbonated beverage consumption further exacerbates this erosive milieu, underscoring the urgency for dental practitioners to adopt meticulous treatment strategies. Existing literature underscores a noteworthy 94% reduction in tooth erosion risk for individuals abstaining from sweetened soft beverages, emphasizing the imperative for a well-devised remineralization protocol to counter demineralized surfaces.

Methodology:
Seventy-three enamel specimens were taken. Forty samples were subjected to pre-operative hardness testing, and five samples were subjected to baseline EDX evaluation followed by grouping of samples (Group 1 = control Group; Group 2 = casein phosphopeptide–amorphous calcium phosphate fluoride [CPP-ACPF] Group; Group 3 = Biomin F Group; and Group 4 = self-assembling peptide [SAP] P-114 Group). A demineralization–remineralization cycle was carried out for 5 days followed by testing through Vickers Microhardness Tester, EDX Evaluation, and Scanning Electron Microscopy (SEM) Imaging. Statistical analysis was performed using one-way analysis of variance followed by intergroup analysis using Tukey’s post hoc test with SPSS software 25.0 version.

Results:
The mean percentage change in microhardness values was 30.05% in Group 1, 24.21% in Group 2, 18.85% in Group 3, and 12.08% in Group 4. The mean Ca/P ratio of samples tested through EDAX was 2.20 at baseline, 1.40 in Group 1 (Control Group), 1.62 in Group 2 (CPP-ACPF), 1.82 in Group 3 (Biomin F), and 2.01 in Group 4 (SAP-P114). Postintervention values were statistically significant from baseline values in both parameters.

Conclusion:
Curodont Protect exhibits superior efficacy, offering valuable insights for future in vivo studies and clinical applications. The multifaceted evaluation, encompassing microhardness testing, SEM analysis, and EDXS assessment, contributes to a nuanced interpretation of the agents’ impact, paving the way for informed decisions in clinical practice and future research endeavors.

Published: May 2024

Context:
Seal the dentin of the pulp chamber during endodontic treatment to avoid interfering with the restorative treatment performed afterward.

Aims:
The aim was to evaluate the effect of three adhesive systems applied in different bonding strategies (etch-and-rinse, self-etch, and universal adhesive) and time-point application (immediately after the cavity access preparation or after endodontic obturation) on the hybrid layer formation and dentinal penetrability.

Materials and Methods:
Forty-eight sound molars were randomly distributed into six groups (n = 10) according to the adhesive system used: Forty-eight sound molars were randomly distributed into six groups (n = 10) according to the adhesive system used and the time-point application: Adper Scotchbond Multi-purpose (AS), Clearfil SE (CF) and Scotchbond Universal (SU) in strategy of immediate endodontic sealing (IES) or delayed endodontic sealing (DES). In IES-AS, IES-CF, and IES-SU groups, dentin sealing was performed immediately after the cavity access, while in DES-AS, DES-CF, and DES-SU, after root canal obturation. The specimens were sectioned in the long axis, in a buccal-lingual direction, and the dentinal penetrability of the adhesive systems was evaluated using confocal microscopy images. Hybrid layer formation was analyzed by scanning electron microscopy images.

Statistical Analysis Used:
Dentinal penetrability data were analyzed with the ANOVA test and the Kruskal–Wallis test was performed for hybrid layer data (α = 0.05).

Results:
IES-CF showed the lowest dentinal penetrability (P < 0.05), while the other protocols were similar to each other (P > 0.05). No significant differences were found between groups regarding the hybrid layer formation (P > 0.05). Immediate and DES protocols do not influence the hybrid layer formation, regardless of the bond strategy used.

Conclusions:
Sealing the pulp chamber dentin before endodontic treatment can improve the bond strength of the final restoration but the formation of the hybrid layer was not influenced by the bond strategy.

Authors: Agarwal Divyanshi , Raghavendra Srinidhi Surya 
Published: May 2024

Aim:
To evaluate cleaning efficacy and debris extrusion of supplementary file systems XP Endo Finisher (XPEF) and XP Endo Finisher R (XPEFR) in endodontic retreatment.

Materials and Methods:
Thirty single-rooted teeth with single canals were selected, canal preparation done till file #30 6% and obturation completed using lateral condensation technique with AH Plus sealer. The samples were stored at 37°C in a 100% humidity incubator for 7 days. The samples were distributed across the three groups according to the method of retreatment (n = 10): Group I: Neo Endo retreatment (NER) files, Group II: NER files + XPEF, and Group III: NER files + XPEFR. Removal of gutta percha using each file system according to the distributed groups was performed. The extruded debris was collected in an Eppendorf tube, dried in a hot air oven, and weighed. Teeth were sliced longitudinally using carborundum discs. Coronal, middle, and apical thirds were assessed for cleaning efficacy under a stereomicroscope. Results were tabulated and subjected to the statistical analysis using the Kruskal–Wallis H-test followed by post hoc turkey HSD test. All statistical tests were carried out at significance level P < 0.05.

Results:
It was seen that Group II (NER files + XPEF) exhibited better cleaning efficacy than Group III (NER files + XPEFR), although the results were not statistically significant. Greater debris extrusion was seen with Group III when compared to Group II.

Conclusion:
Supplementary files XPEF/XPEFR enhance the cleaning efficacy in endodontic retreatment, but the debris extrusion of XPEFR is more than XPEF.
Phase retrieval on circles and lines
Authors: Chalendar Isabelle , Partington Jonathan R. 
Published: May 2024

AbstractLet f and g be analytic functions on the open unit disk
${\mathbb D}$
such that
$|f|=|g|$
on a set A. We give an alternative proof of the result of Perez that there exists c in the unit circle
${\mathbb T}$
such that
$f=cg$
when A is the union of two lines in
${\mathbb D}$
intersecting at an angle that is an irrational multiple of
$\pi $
, and from this, deduce a sequential generalization of the result. Similarly, the same conclusion is valid when f and g are in the Nevanlinna class and A is the union of the unit circle and an interior circle, tangential or not. We also provide sequential versions of this result and analyze the case
$A=r{\mathbb T}$
. Finally, we examine the most general situation when there is equality on two distinct circles in the disk, proving a result or counterexample for each possible configuration.

Authors: Nitzke Douglas , Czermainski Juliana , Rosa Carolina , Coghetto Chaline , Fernandes Sabrina Alves , Carteri Randhall B 
Published: May 2024

BACKGROUND
Type 2 diabetes is a chronic, non-communicable disease with a substantial global impact, affecting a significant number of individuals. Its etiology is closely tied to imbalanced dietary practices and sedentary lifestyles. Conversely, increasing die-tary fiber (DF) intake has consistently demonstrated health benefits in numerous studies, including improvements in glycemic control and weight management.
AIM
To investigate the efficacy of DF interventions in the management of type 2 diabetes mellitus (T2DM).
METHODS
A systematic literature review was conducted to explore the association between DF intake and the management of T2DM. Following the inclusion and exclusion criteria, a total of 26 studies were included in this review.
RESULTS
The main strategies implied to increased DF intake were: High DF diet plus acarbose (2 studies); DF supplements (14 studies); and high DF diets (10 studies). Overall, most studies indicated that increased DF intake resulted in im-provements in glycemic control and weight management in T2DM patients.
CONCLUSION
DF represents a valuable strategy in the treatment of type 2 diabetes, improving health outcomes. DF intake offers the potential to improve quality of life and reduce complications and mortality associated with diabetes. Likewise, through supplements or enriched foods, DF contributes significantly to the control of several markers such as HbA1c, blood glucose, triglycerides, low-density lipoprotein, and body weight.
