Evaluation of Gastropods as Biomaterials: Monodonta turbinata (Born, 1780)
Authors: Uğurlu Erkan
Published: November 2023

Monodonta turbinata is a densely populated species along the coasts of İskenderun Bay, Mediterranean Sea. The shells of M. turbinata contain a high amount of chitin for the chitosan production. The goal of this research is to produce chitin and chitosan from M. turbinata shells and characterize them using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) techniques. In addition, the samples were analyzed for solubility and deacetylation degree. The yields of chitin and chitosan obtained from M. turbinata were calculated as 60.26±0.96% and 80±1.29%, respectively. FTIR spectrum analysis results revealed the existence of functional groups in various bands and confirmed that the samples were chitin and chitosan. As a result of the FTIR, the deacetylation degree (DD) value was established to be 84.83%. The crystalline index (CrI) of chitin obtained from shells was computed as 54.92%. SEM analysis results displayed the morphological differences between chitin and chitosan biopolymers. The results indicate that M. turbinata shells, a waste product from İskenderun Bay, hold promise as a chitin and chitosan source for various applications in Türkiye.
Overcoming Mission Competition in Departments of Family Medicine
Authors: Campbell Kendall M. , Schlag Karen E. , Oni Keyona , Amaechi Octavia , Foster Krys E. , Walcher Christen , Porterfield Laura
Published: November 2023

Departments of family medicine are centered around the tripartite mission of education, research, and clinical care. Historically, these three missions have been balanced and interdependent; however, changes in the funding and structures of health systems have resulted in shrinking education and research missions and an increased emphasis on clinical care. In the wake of waning state and federal contributions to primary care research, many departments of family medicine have adopted a private practice approach. This approach is centered on generating revenue for the institution, incentivizing physicians to remain clinically focused through productivity and intense attention to volume targets. As a department’s focus shifts to the clinical care mission, education and research are increasingly neglected and underresourced. Meanwhile, the administrative burden of electronic health records (EHRs) has further encroached on time previously allocated to research, with the EHR burden disproportionately affecting the primary care workforce. To counteract mission competition in departments of family medicine and to recover the vital missions of education and scholarship, devising a clear plan for reclaiming and sustaining a tripartite mission is important. Advocating for increased primary care research funding, enhancing EHRs, balancing clinical and education metrics, and supporting primary care research, especially for groups underrepresented in medicine, are interventions to help fully support education and research missions and to recover and sustain mission balance in departments of family medicine.

Authors: Karimullah Suud Sarim
Published: November 2023

The study explores the relevance of the concept of justice in Islamic law to complex and pressing contemporary humanitarian issues. Through the literature study method with integrative and comprehensive literature analysis, this study conducts a deep and structured investigation of the existing literature to summarize and synthesize relevant views, arguments, findings, and thoughts. The study results stated that the concept of justice in Islamic law is a central aspect of Islamic religious teachings and has broad applicability in dealing with various humanitarian challenges today. Through a deep understanding of the concept of justice in Islamic law, societies can form solid moral views and act effectively to promote human rights, address economic inequality, facilitate peace, and respond to other humanitarian issues. This makes it possible to view the concept of justice in Islamic law not only as a religious aspect but also as a potential source of inspiration for building a more just and sustainable world for all human beings, regardless of their religious or cultural background.
Heart rate variability biofeedback acutely improves attentional control only in highly stressed individuals
Authors: Blaser Berenike , Weymar Mathias , Wendt Julia
Published: November 2023

Vagally mediated heart rate variability is an index of autonomic nervous
system activity that is associated with a large variety of outcome
variables including psychopathology and self-regulation. While
practicing heart rate variability biofeedback over several weeks has
been reliably associated with a number of positive outcomes, its acute
effects are not well known. Because the strongest association with heart
rate variability has been found particularly within the
attention-related subdomain of self-regulation, we investigated the
acute effect of heart rate variability biofeedback on attentional
control using the revised Attention Network Test (ANT-R). Fifty-six
participants were tested in two sessions. In one session each subject
received a heart rate variability biofeedback intervention, and in the
other session a control intervention of paced breathing at a normal
ventilation rate. After the biofeedback or control intervention,
participants completed the ANT-R using the Orienting Score as a measure
of attentional control. Mixed models revealed that higher resting
baseline heart rate variability (RMSSD) was associated with better
performance in attentional control, which suggests more efficient
direction of attention to target stimuli. There was no significant main
effect of the intervention on attentional control. However, an
interaction effect indicated better performance in attentional control
after biofeedback in individuals who reported higher current stress
levels. The results point to acute beneficial effects of heart rate
variability biofeedback on cognitive performance in highly stressed
individuals. Although promising, the results need to be replicated in
larger or more targeted samples in order to reach stronger conclusions
about the effects.

Heavy metal-polluted soils have grown ubiquitous worldwide due to increased geologic and anthropogenic activity, and the plants growing in these soils exhibit decreased growth, performance, and yield. Contaminated soil with heavy metals has become a concern for agricultural scientists because of the progress made in agricultural product safety. Heavy metals are metalloids with biological toxicity. The most common are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn). These metals exist throughout the terrestrial environment and have spread out due to anthropogenic and natural activities. Soil heavy metal pollution leads to human health risks, groundwater pollution, plant phytotoxicity, and a decline in crop and soil production. Bioremediation is an effective method of treating heavy metal-polluted soils. It is a widely accepted method that is mostly carried out in situ; hence it is suitable for the establishment/reestablishment of crops on treated soils. Using plants in the treatment of polluted soils is a more common approach in the bioremediation of heavy metal-polluted soils. Bioremediation ensures a more efficient clean-up of heavy metal-polluted soils. However, the success of this approach largely depends on the species of organisms. This paper is aimed to review the hazardous effects of heavy metal toxicity on soil and plants and their bioremediation. This paper also discusses numerous strategies for addressing heavy metal contamination in soil. Keywords: heavy metals, anthropogenic sources, natural sources, bioremediation

Although the Lesser Kestrel (Falco naumanni, Fleischer, 1818) was a widespread species in Bulgaria, there are no detailed surveys on its biology and ecology like the ones implemented in countries still harbouring abundant populations, such as Spain, Italy, Greece, etc. After 2014 when “Green Balkans”, as a breeder, launched the reinforcement of the species and its recovery in Bulgaria now it is possible to study the species using modern technologies and methods like radio and satellite transmitters. The known roost sites (n=12), the subject of our study, are located from 55 to 745 m above the sea level, as the main part of them is situated about 100 - 200 m above the sea level. The most numerous roost site, which is located in the North-eastern Greece, is comprised of about 80 individuals but in the other roost sites the number of the Lesser Kestrel reach 20-40 individuals. During the period 2014 - 2021 the Lesser Kestrels in the largest known colony of the species in Bulgaria, which is located in SPA Sakar, have used different high voltage pylons from the same power lines, alternating pylons depending on the type of agricultural crops in the area. It has been found that the birds express preferences for cereal crops around high voltage pylons, which they use as roost sites. Keywords: communal roost sites, LIFE for Lesser Kestrel, post-breeding dispersal.

Authors: DP Leite-Jr
Published: November 2023

Introduction: Yeast species of the genus Candida are important human pathogens and cause 90% of existing fungal infections. These pathogens within the One Health vision are closely linked to human, animal and environmental health. Objective: To emphasize the importance of the status of Candida yeasts, as infectious, opportunistic and emerging agents. Methodology: Databases and books relevant to the subject were used. Results: Candidemia is the most hostile fungal infection in the studied populations. Several cases of superficial and invasive diseases involve isolation of these yeasts in various population groups. Parenteral nutrition, administration of broad-spectrum antibiotics, prolonged hospitalization, chemotherapy and vascular catheters were considered risk factors. C. albicans is the most prevalent species, followed by C. parapsilosis, C. tropicalis and C. glabrata and more recently by the appearance of a new pathogen C. auris. Yeasts of the genus Candida are associated with a high lethality rate in relation to hematological malignancies, mainly C. albicans. Discussion: The pathogenic prevalence of Candida spp. is recognized all over the world. Candida albicans is the most commonly isolated species from clinical materials. The literature discusses methods used to differentiate strains in the study of the epidemiological relationship of members of the genus listed in this review. New Candida species isolated from clinical specimens continue to grow each year. Conclusion: Candidemia is a prevalent pathology with high incidence, morbidity and mortality in the world. The taxonomy, mechanisms of action and status of this yeast genus are related to its virulence, adhesion and epidemiological characteristics, more suitable for treatments to control cases of fungal infections caused by yeasts of the genus Candida.
ЭССЕ О ЦЕННОСТИ НАУЧНОГО ДОКУМЕНТА
Authors: Лазарев Владимир
Published: November 2023

Рассмотрена терминологическая путаница, связанная с наименованиями свойств научных документов, отображаемых фактом их цитируемости. В очередной раз аргументируется утверждение, что непосредственно цитируемость научных документов отражает их использование, которое, в свою очередь, отражает их ценность. Необходимость продолжения соответствующей полемики и усиления аргументации вызваны тем, что многие авторитетные специалисты либо не ассоциируют цитируемость с ценностью, либо безразличны к вопросу о свойстве документов, отображаемых цитируемостью (будучи при этом озабочены «совершенствованием индикаторов», отображающих неназванное ими свойство), либо смешивают ценность документа с его качеством. Более того, существует авторитетная точка зрения (напр., Bornmann & Daniel, 2008; Tahamtan & Bornmann, 2019), согласно которой

использование – лишь один из факторов, вызывающих цитируемость научных документов; при этом обращения к документам считаются, напротив, рядом специалистов несомненным свидетельством их использования, в то время как в этом случае в действительности остается неизвестным, будет ли полный текст затребованного документа хотя бы бегло просмотрен пользователем. Эти вопросы получают в эссе свое критическое рассмотрение. Высказывается

мнение, что путаница с понятием «использование документа» связано с невольным смешиванием его с традиционной библиотечной концепцией «использования фонда». Показано, как приятие к рассмотрению философского понятия ценности может внести еще больше путаницы в терминологию, используемую для обозначения свойства научного документа, отражаемого par

excellence его цитируемостью. Критически проанализированы существующие

в библиотековедении определения «ценности документа». Предпринимается попытка уточнения понятий и содержания терминов «ценность научного документа» и «использование научного документа».
Water sensitive design features: their function and effectiveness over ten years in a botanic garden
Authors: Simpkins Emma , Simcock Robyn , Stanley Rebecca , Hobbs Jack
Published: November 2023

Water sensitive design (WSD) is a nature-based solution to urban stormwater problems which involves intercepting rainfall and stormwater from impervious surfaces using a range of devices. These devices rely on soils and plants to slow water flows, reduce water volumes and improve the quality of the water reaching our rivers, streams, lakes and oceans. Common devices used in Auckland, New Zealand are rain gardens and swales. Auckland Botanic Gardens (ABG) has applied a variety of these devices, often in ‘treatment trains’ and focusing on the use of native New Zealand plants, to solve an on-site environmental problem. ABG additionally supports research, advocates for the selection and effective maintenance of the native New Zealand plants, and educates the public about WSD. Recommendations for plant selection in Auckland for rain gardens and swales are made based on ten years of observations and trials at ABG.

The mathematics performance of Swedish deaf and hard‐of‐hearing students was compared to that of hearing students to relate the situation in Sweden to recent international research results. Quantitative analysis of performance on the national subject test in mathematics and questionnaire on demographic variables for the deaf and hard‐of ‐hearing students were used. Analyses showed significant differences overall between deaf and hard‐ofhearing students and their hearing counterparts, but more importantly, gave insight into specific areas in which deaf and hard‐of‐hearing students may succeed or falter. In the study no significant differences in mathematics performance appeared between the deaf and hard‐of‐hearing students if sign language or spoken language was used as the language of instruction. No significant differences appeared depending on investigated background variables between the two groups, students mainly taught in sign language (class for the deaf) and students mainly taught in spoken language (class for the hard‐of‐ hearing). Demographic variables investigated were students’ gender, hearing status, additional functional disability, born is Sweden or not as well as parents’ hearing status, level of education, born is Sweden or not. The study serves as a basis for further investigations to develop deaf and hard‐of‐hearing students’ performance in mathematics.

Published: November 2023

Objective:
This study aimed to investigate the prevalence of oral mucosal lesions (OMLs) in adult patients who did and did not use tobacco, their habits, and the relative risk of developing oral lesions associated with these habits.
Methods:
The present study was a case-control, descriptive, and clinical-pathological investigation, which included 136 subjects, who visited a private dental university in Riyadh. The subjects were divided equally into two groups; the case group and the control group. The type, frequency, duration, and time of tobacco use were recorded. The participants' oral mucosa was systematically examined, and any alterations or abnormalities were analyzed.
Results:
In the case group, the correlation between tobacco use and the presence of lesions was positively significant (P=0.0001). The frequency and duration of tobacco exposure since the commencement of the habit and the age of the individual were not associated with the presence of OMLs (P˃0.05).
Conclusion:
This study was conducted to investigate the prevalence of oral mucosal lesions (OMLs) in adult patient's users and non-users of tobacco. Tobacco users had a significantly higher risk of developing oral mucosal lesions as compared to non-tobacco users. The type and location of oral mucosal lesions varied based on the type and duration of tobacco use.
Braucht der Personzentrierte Ansatz eine „relationale Wende“?
Authors: Steffen Markus
Published: November 2023

Mit dem Begriff „relationale Wende“ beschreibt Frank Staemmler einen „postmodernen Paradigmenwechsel“ in der Psychotherapie von einem bisher stark „individualistisch“ hin zu einem zunehmend „dialogischen“ Verständnis des Konstrukts „Selbst“. Die Selbstkonzeption von Rogers stellt er dabei als eine (noch) nicht relationale dar. Ein Blick in die Theorie der Selbstentwicklung des Personzentrierten Ansatzes zeigt aber gerade das Gegenteil: Rogers und insbesondere Gendlin haben die relationale Perspektive in ihren Theorien früh mitgedacht geradezu vorweggenommen.

A los pacientes se les realizó una historia clínica odontológica completa que incluyó un examen extraoral, intraoral, índice de placa bacteriana, se tomaron impresiones dentales y se obtuvieron modelos de estudio para describir las características bucodentales. Se determinó en 8 casos dentición permanente, predominancia de perrfil facial recto, sobremordida horizontal entre 4-9 mm,-mordida abierta anterior y los pacientes fueron en su mayoría euriprosopos. Se sugiere que la deficiencia muscular funcional en sujetos con IMOC parece inducir patrones faciales de caras cortas y anchas (euriprosopos), mordidas abiertas y alteraciones en la longitud de los arcos dentales. Un tratamiento preventivo de estas anomalías faciales y bucodentales en IMOC debiera incluir un diagnóstico temprano con terapia facial miofuncional y ortopedia dental. Estudios clínicos controlados son necesarios para determinar esta hipótesis.

Published: November 2023

Este artículo presenta un protocolo de examen físico para pacientes con desórdenes temporomandibulares y dolor orofacial. El proceso de evaluación clínica, posterior a la historia clínica, es finalizado por medio de un examen físico y el uso de estrategias adicionales. Cuando estas son necesarias pueden incluir pruebas de provocación, ayudas diagnósticas e interconsultas. Esto le permitirá al clínico hacer una conexión adecuada con los datos recolectados en la historia clínica lo cual ayudará al establecimiento del diagnóstico diferencial y de igual manera a plantear acertadas estrategias de manejo.

En el Centro de Salud Diego Lalinde Zawadski (DLZ), ubicado en la zona oriental del municipio de Santiago de Cali, surgió la necesidad de evaluar a los escolares de su área de influencia que recibieron acciones de promoción en salud bucodental. Se planteó un estudio descriptivo cuyo objetivo fue evaluar los conocimientos, las prácticas en salud bucodental, el estado de higiene oral, el estado de dentición y de las necesidades de tratamiento de los alumnos de las sedes educativas Santísima Trinidad y Nuestra Señora de Fátima, de las cuales la primera recibió las acciones de promoción de manera continua y permanente y la segunda las recibió de manera parcial o esporádica.
Se seleccionaron al azar 124 escolares de ambas escuelas que cursaban de segundo a quinto grado cuyas edades fluctuaron entre 7 y 12 años, quienes fueron autorizados o por ambos padres de familia, o por las madres de familia o por sus acudientes, mediante un consentimiento informado y se les aplicó una encuesta previamente probada. En los resultados de ambas sedes educativas no se encontraron diferencias significativas respecto a conocimientos en salud bucodental.
Comparando las sedes, en la Santísima Trinidad hubo una mayor proporción de escolares que se cepillaban 4 veces (21.3%) y menor proporción de escolares dentro de la categoría mala (6.6%) de IPC que en Nuestra Señora de Fátima. Los componentes del índice ceo-d en la Santísima Trinidad mostraron una ligera tendencia a presentar menor promedio de dientes cariados (1.8) que en la otra institución (2.0). El índice CPO-D en La Santísima Trinidad (2.7) fue ligeramente menor que en Nuestra Señora de Fátima (2.8). En la escuela Santísima Trinidad (62.2%) hubo mayor proporción de dientes permanentes sin necesidad de tratamiento con respecto a Nuestra Señora de Fátima (56.4%). Aunque no fue de manera estadísticamente significativa los escolares de la Santísima Trinidad, intervenida constantemente por la campaña de promoción del Centro de Salud Diego Lalinde, muestran menor proporción de IPC de categoría mala y promedio de dientes cariados que la institución poco intervenida, por lo que se recomienda seguir impartiendo las campañas de manera frecuente con énfasis en el cepillado dental.

Por la incertidumbre existente con respecto a la posible relación entre los desórdenes respiratorios y las alteraciones del crecimiento y desarrollo del macizo craneofacial, con esta investigación se pretendió hacer un aporte al conocimiento científico mediante la obtención de datos claves acerca de la elaboración, calibración y validación de instrumentos confiables para la medición del flujo de aire, las caídas asociadas a la presión del aire inspirado y/o espirado y la resistencia nasal, en aras de poder cuantificar los valores de normalidad de la función respiratoria. Para tal efecto se diseñaron, construyeron, calibraron y se utilizaron experimentalmente instrumentos de medición de la función respiratoria. Como resultado de lo anterior, se obtuvieron curvas de calibración, tanto para el flujo de aire como para la diferencia de presión, que presentaron coeficientes de correlación (r) de 0.9997 y 0.9992, respectivamente. Mediante el uso de un espirómetro y un neumotacógrafo junto con transductores de presión conectados a un polígrafo, empleando una muestra por conveniencia compuesta por cuarenta y cuatro sujetos infantiles, con edades que oscilaron entre los seis y los doce años, se realizó un estudio piloto. En experimentos separados sobre los mismos sujetos y el uso dispositivos externos independientes, con el objeto de establecer la partición oral/nasal en la espiración espontánea de los sujetos en reposo se colectaron simultáneamente los gases espirados por vía nasal y oral durante un lapso de ocho minutos. Se registraron curvas de flujo de aire por vía nasal y de diferencias de presión orofaringe-máscara en niños sentados y en reposo. Sobre los trazados se calcularon el flujo medio de aire durante la inspiración y la diferencia media de presión orofaringe-máscara durante la misma fase, valores con los cuales se calculó la resistencia inspiratoria media de la vía nasal. Los valores de la resistencia nasal obtenida cayeron dentro del rango normal. Los resultados de esta prueba piloto mostraron baja correlación en la mayoría de los cruces de las variables respiratorias medidas para los niños estudiados, lo que demandaría en futuros estudios el trabajar con una muestra mayor que la utilizada en el presente proyecto de investigación.

Published: November 2023

La agenesia dental o ausencia dental congénita, es un síndrome que se manifiesta en diversas poblaciones del mundo y genera múltiples consecuencias si su diagnóstico no se realiza oportunamente. Para determinar su prevalencia en los pacientes de cuatro Instituciones Prestadores de Servicios de Salud (IPS) del sector privado de Santiago de Cali se realizó un estudio descriptivo a partir de la revisión de 1.440 historias clínicas con sus correspondientes radiografías panorámicas. Estos registros pertenecían a usuarios de las cuatro instituciones cuyas edades oscilaron entre 14 y 21 años. Determinada la agenesia dental en 141 de las radiografías, se procedió a verificar clínica-mente el impacto de la anomalía para establecer la correlación de la falta de formación de los gérmenes dentales con algunas variables como género, edad, grupo de dientes afectado, tipos de dientes, cantidad de dientes faltantes por la patología de desarrollo, cuadrantes y arcadas involucradas. Además se tomó nota de la posible presencia de algún síndrome que pudiera estar relacionado con la falta genética. Se puso especial atención en la proporción de agenesia de terceros molares respecto a los otros grupos de dientes afectados.

White spots: manchas blancas en el esmalte asociadas a tratamiento ortodóncico con aparatología fija
Authors: Barrera Lina
Published: November 2023

Resumen: Uno de los problemas del tratamiento ortodoncia es el mantenimiento de una adecuada higiene oral del paciente. La aparatología fija ortodóncica predispone al aumento y acumulación de la placa y la desmineralización del esmalte lo cual puede manifestarse pocas semanas después de colocada la aparatología. La evidencia clínica mas temprana es la aparición de una mancha blanca opaca en el esmalte que preocupa al ortodoncista y al paciente debido a que es una lesión potencialmente irreversible, no saludable y antiestética. La presente revisión bibliográfica describe algunos de los métodos para la prevención de las manchas blancas en el esmalte sean aplicados por el ortodoncista o por el paciente.
¿Es la enfermedad periodontal un factor de riesgo cardiovascular? Revisión de la evidencia experimental y clínica.
Authors: Hernán Ramírez Jorge
Published: November 2023

Resumen: Recientes estudios epidemiológicos de riesgo cardiovascular hansugerido una relación entre la enfermedad periodontal con el desarrollo de ateroesclerosis. Unmecanismo probable de este vínculo es la alteración de la función endotelial por el estadoinflamatorio sistémico de la enfermedad periodontal. La disfunción endotelial en pacientes conenfermedad periodontal ha sido expuesta en varios estudios epidemiológicos de corte transversal yalgunos estudios recientes de intervención periodontal. El impacto del tratamiento periodontal parala prevención de las enfermedades cardiovasculares debe ser aclarado en futuros ensayos clínicos amayor escala. Sin embargo, la posibilidad de que el tratamiento periodontal disminuye lamorbi-mortalidad cardiovascular puede tener un impacto importante en las políticas de salud pública,donde las enfermedades cardiovasculares son la primera causa de mortalidad en Colombia y muchosotros países. El propósito de este artículo es identificar las principales relacionesfisiopatológicas entre la periodontitis y la enfermedad cardiovascular. Revista Estomatología 2005;13(2): 18-26. Palabras clave: Enfermedad cardiovascular. Eetiología. Prevención. Enfermedadperiodontal. Disfunción endotelial. Summary: Recent studies addressing cardiovascular risk factorssuggest a relationship between periodontal disease and the development of atherosclerosis. Aprobable mechanism of this link is the alteration of the endothelial function by the systemicinflammatory state related to periodontal disease. The endothelial dysfunction in patients withperiodontal disease has been exposed in several cross-sectional epidemiological studies and somerecent studies of periodontal intervention (clinical trials). The impact of the periodontaltreatment in the prevention of cardiovascular diseases has to be clarified in future and biggerclinical trials. Nevertheless, the possibility that the periodontal treatment diminishescardiovascular morbimortality may have an important impact in public health policies, sincecardiovascular diseases are the first cause of mortality in Colombia and many other countries. Theaim of this paper is to identify the main physiopathological relationships between periodontitis andcardiovascular disease. Key words: Cardiovascular disease. Aetiology. Prevention.

Estudio del comportamiento de un dentífrico que contiene óxido de aluminio hidratado (alúmina) como sustancia abrasiva sobre el esmalte dental
Authors: Baraya Martínez Aristides , Mejía Pavoni Carlos
Published: November 2023

El presente estudio demuestra que al efectuar un cambio en el componente abrasivo de un dentífrico (sílica por alúmina) no ocasiona ningún daño a la estructura del esmalte; es decir, no altera físico-químicamente a este tejido. La alúmina como sustancia abrasiva del dentífrico no mancha ni decolora las obturaciones plásticas presentes en la superficie libre de los dientes, esto es, se comporta como una sustancia neutra ante la producción de pigmentos tanto al tejido como a los materiales dentales, fácilmente pigmentables, por otra parte su capacidad de abrasión es inferior al comparase con la sílica. Se describe una comparación entre un grupo experimental y otro de control, que fueron sometidos por procedimiento de laboratorio a técnicas especiales donde se obtendría una específica relación abrasión - esmalte - pigmentación. La condición del estudio, en forma aleatoria y de carácter experimental in vitro prospectivo, permitió conocer el desempeño de esta sustancia abrasiva, como componente de una nueva y avanzada serie de dentífricos para las futuras décadas.
