Authors: González-Rojas Mariela , Murillo-Cruz Rafael , Virginio-Filho Elías De Melo , Ávila-Arias Carlos
Published: March 2018

El estudio se realizó en sistemas agroforestales (SAF) con café asociado a maderables de cedro amargo (Cedrela odorata. L.) en el cantón de Pérez Zeledón, provincia de San José, Costa Rica. Se establecieron 39 parcelas temporales de muestreo de 1000 m2, con el objetivo de evaluar el efecto de las características biofísicas y de manejo sobre el crecimiento en diámetro (DAP) y altura total (HT) del cedro amargo de los dos a los 17 años de edad. El crecimiento de la especie varió en un rango de 2 a 3 cm año-1 en DAP y 1,6 a 2,2 m año-1 en altura. Las variables biofísicas que influyeron negativamente el crecimiento del cedro fueron el aumento de la altitud sobre el nivel del mar (msnm), una mayor abundancia de árboles por hectárea, el aumento del contenido de cobre en el suelo y una mayor frecuencia de limpiezas químicas anuales. Se obtuvieron modelos de regresión múltiple que explicaron el crecimiento de la especie (VT árb-1e IMA VT árb-1) a partir de variables biofísicas. La abundancia de árboles de cedro por hectárea óptima correspondió a un rango entre 72 a 96 árb ha-1 desde el establecimiento hasta el ciclo final. La especie se desarrolló mejor a una altitud entre 608 y 707 msnm, en pendientes inferiores a 21 % y suelos con contenidos menores a 3,6 mg l-1 de Cu, 165 mg l-1 de Fe, pH mayor de 4,9 y una relación Ca Mg-1 mayor a 4,1.

Authors: Villalobos-Barquero Verónica , Meza-Montoya Alejandro
Published: March 2018

Se evaluó la operación de arrastre en cinco fincas ubicadas en Sahara de Bataán (entre las coordenadas 83°20'32"O, 10°05'09"N), Limón, Costa Rica.  Mediante un estudio de tiempos (T) y movimientos (M)) se recolectaron datos de dos condiciones de aprovechamiento: raleo y tala rasa, dos métodos de arrastre con búfalos: sulky y cadenas, así como de los distintos búfalos utilizados: búfalo 1 y búfalo 2.  Se verificó por medio de pruebas de normalidad, análisis de varianzas, prueba de Tukey (distribución de datos normales) y Bonferroni (distribución de datos que no mostraron un comportamiento normal) las siguientes hipótesis: Ho: No existe diferencia estadística entre: a) tratamiento silvicultural aplicado, b) método de arrastre utilizado y c) búfalo utilizado para el arrastre y la Ha: existe diferencia estadística entre los grupos de datos antes mencionados.

Las variables evaluadas fueron distancia de arrastre en metros (D), número de fustes arrastrados (N), duración total de la jornada en horas (T), volumen en metros cúbicos (V), eficiencia en porcentaje (E) y producción en metros cúbicos por hora, el análisis se realizó para cada uno de los ciclos de producción y para cada una de las jornadas evaluadas.

Con el propósito de predecir la producción del arrastre de madera en troza con búfalos de agua, se construyeron modelos de regresión según la metodología propuesta por Hughell (1990).  Las ecuaciones de mejor ajuste fueron escogidas según variables como el coeficiente de variación y el coeficiente de determinación R2 ajustado y  fueron validadas con un 25% de los datos previamente aislados y escogidos al azar.

Se obtuvieron dos modelos para estimar la producción de madera en troza de melina arrastrada por el búfalo en dos condiciones de aprovechamiento: raleo (a) y tala rasa (b), los cuales se muestran a continuación:

a)   Producción (m3/h) = 1,633 + 0,154*V – 0,002*D – 0,109*T, con un R2 de 93,2%.

 

b)   Producción (m3/h) = 5,042 + 0,199*V - 0,001*D - 0,275*T - 0,041*E, con un R2 de 86,7%.

Authors: Lizano-López Marvin Vinicio
Published: March 2018

Se analizó la estructura horizontal mediante resultados de abundancia y dominancia absoluta para seis especies de árboles maderables, en bosques intervenidos de la Zona Norte de Costa Rica. Se eligieron 30 Unidades de Manejo Forestal (UMF), con áreas efectivas de bosque ≥ 30 ha, se dividieron en dos sectores. Se consideró información de 434 parcelas, con datos procedentes de inventarios preliminares (dap ≥ 10 cm y 30 cm). Se obtuvo datos del censo con dap ≥ 60 cm; para un total de área efectiva de 3284,8 ha. Los resultados demostraron que Dipteryx panamensis, especie con restricciones de corta en Costa Rica, es abundante en las áreas muestreadas en el sector 2. Se obtuvo resultados  >  4,22 individuos por hectárea con dap ≥ 10 cm. Tachigali costaricensis, especie vedada en Costa Rica, se distribuyó mejor según los valores de abundancia absoluta (N/ha), dentro del sector 2 (p = 0,0026, Wilcoxon); se consideró como una especie abundante (3,36 N/ha) y dominante (0,406 m²/ha) en este mismo sector (dap ≥ 10 cm). Las especies Hymenolobium mesoamericanum y Lecythis ampla, son árboles poco abundantes, por consiguiente, poco dominantes es este estudio. Es importante reconsiderar la situación de Lecythis ampla, debido que en Costa Rica no existen restricciones de corta para esta especie..
Trazabilidad de la varilla de acero para construcción #3 en ArcelorMittal Costa Rica
Authors: Vásquez-Granados Alberto , Abarca-Guerrero Liliana
Published: March 2018

La industria constructiva transforma materias primas en productos elaborados o semielaborados. Dentro de ésta se encuentra la industria del acero, a la cual se le atribuyen grandes impactos ambientales por la intensidad en el uso de recursos durante su proceso productivo. Para determinar dichos impactos existen hoy día metodologías como el Análisis de Ciclo de Vida (ACV), que permite cuantificar y evaluar los impactos ambientales potenciales asociados a procesos o productos durante las etapas de su existencia. En el presente estudio se determinó la trazabilidad de la varilla de acero para construcción #3 en la empresa ArcelorMittal Costa Rica, en las etapas de producción y transporte del lingote de acero y la producción y transporte de la varilla de acero. Se creó un inventario de las entradas y salidas de cada etapa del ciclo de vida y se evaluó mediante el software SimaPro 8.2.3, empleando las bases de datos de Ecoinvent. Con la evaluación de impacto de ciclo de vida (EICV), se obtuvo que los mayores impactos se produjeron en la etapa de producción del lingote de acero, como consecuencia del uso de materias primas vírgenes. Durante el transporte del lingote se determinó que el transporte en tren genera más impacto que el transporte en buque por kilómetro recorrido transportando una tonelada del material. Para la etapa de producción de la varilla los mayores impactos se asocian a la emisión de gases desde la chimenea del horno. Finalmente, en el transporte de la varilla se demostró que a mayor peso transportado se consume más combustible, por lo que existe una proporcionalidad.

Published: March 2018

El presente trabajo muestra la importancia del uso de las TI’s  (Tecnologías de la Información) como herramientas de consulta para los productores en mediana y pequeña escala de agricultura protegida; donde se establece la necesidad de acceder a portales en internet o aplicaciones móviles, que provean de información acerca de precios de mercados, alertas de clima y plagas, centros de investigación, financiamientos, apoyos gubernamentales, proveedores de insumos y de servicios, requisitos de clientes, casos de éxito, etc., y de esta manera puedan tomar decisiones que les permita proyectar sus futuras producciones e incrementar su nivel de competitividad; lo anterior para evitar en lo posible intermediarios y obtener mejores ganancias. Además se podrá observar que invertir en TI’s diseñadas para reunir y proveer información completa, confiable, en tiempo real y de diversas fuentes, aunada a un buen uso de estas; disminuirá la incertidumbre en los pequeños productores de agricultura protegida. Se presentarán diversos portales consultados en Internet, así como aplicaciones móviles y sistemas de mensaje de textos para celulares desarrollados en diferentes países por instancias públicas y privadas; que muestran información de algún eslabón de la cadena de valor agrícola, de interés para los productores. Desafortunadamente esta información se encuentra en diferentes medios y el consultante debe navegar entre éstos lo que implica invertir tiempo en la consulta; además debe tener conocimientos en el uso de estas tecnologías, para que pueda crear una visión completa que le ayude a tomar decisiones de acuerdo a la información obtenida.

Oral Dysbiotic Communities and Their Implications in Systemic Diseases
Authors: Sudhakara Preethi , Gupta Abishek , Bhardwaj Anshumouli , Wilson Aruni
Published: March 2018

The human body supports the growth of a wide array of microbial communities in various niches, such as the oral cavity, gastro-intestinal and urogenital tracts and on the surface of the skin. These host associated microbial communities include yet-un-cultivable bacteria and are influenced by various factors. Together, these communities of bacteria are referred to as the human microbiome. Human oral microbiome consists of both symbionts and pathobionts. Deviation from symbiosis among the bacterial community leads to “dysbiosis”—a state of community disturbance. Dysbiosis occurs due to many confounding factors that predispose to a shift in the composition and relative abundance of microbial communities. Dysbiotic communities have been a major cause for many microbiomes related systemic infections. Such dysbiosis is directed by certain important pathogens called the “keystone pathogens” that could modulate community microbiome variations. One such persistent infection is oral infection, mainly periodontitis, where a wide array of causal organisms has been implied to systemic infections such as cardio vascular disease, diabetes mellitus, rheumatoid arthritis and Alzheimer’s disease. The keystone pathogens co-occur with many yet-cultivable bacteria and their interactions lead to dysbiosis. This has been the focus of recent research. While immune evasion is one of the major modes that lead to dysbiosis, new processes and new virulence factors of bacteria have been shown to be involved in this important process of that determine disease or health state. This review focuses on such dysbiotic communities, their interactions and their virulence factors that predispose the host to other systemic implications.
Hazard Quotients, Hazard Indexes, and Cancer Risks of Toxic Metals in PM10 during Firework Displays
Authors: Pongpiachan Siwatt , Iijima Akihiro , Cao Junji
Published: March 2018

Bonfire night is a worldwide phenomenon given to numerous annual celebrations characterised by bonfires and fireworks. Since Thailand has no national ambient air quality standards for metal particulates, it is important to investigate the impacts of particulate injections on elevations of air pollutants and ecological health impacts resulting from firework displays. In this investigation, Pb and Ba were considered potential firework tracers because their concentrations were significantly higher during the episode and lower than/comparable with minimum detection limits during other periods, indicating that their elevated concentrations were principally due to pyrotechnic displays. Pb/Ca, Pb/Al, Pb/Mg, and Pb/Cu can be used to pin-point emissions from firework displays. Air mass backward trajectories (72 h) from the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model indicated that areas east and north-east of the study site were the main sources for the air transportation. Although the combined risk associated with levels of Pb, Cr, Co, Ni, Zn, As, Cd, V, and Mn was far below the standards mentioned in international guidelines, the lifetime cancer risks associated with As and Cr levels exceeded US-EPA guidelines, and may expose inhabitants of surrounding areas of Bangkok to elevated cancer risk.
Exchange Flow Variability between Hypersaline Shark Bay and the Ocean
Authors: Hetzel Yasha , Pattiaratchi Charitha , Mihanović Hrvoje
Published: March 2018

In Shark Bay, a large hypersaline bay in Western Australia, longitudinal density gradients force gravitational circulation that is important for Bay-ocean exchange. Observations of vertical stratification and velocity are presented, confirming a steady near-bed dense water outflow from Shark Bay’s northern Geographe Channel that persisted through all stages of the tide. Outflow velocities were 2–3 times stronger than the outflows recorded previously in Naturaliste Channel (in the west) and were more resistant to breakdown by tidal mixing. Estimates of turbulent kinetic energy production derived from ADCP data using the variance method showed a more complex structure in Geographe Channel, due to shear associated with the stratified conditions, with peak levels of turbulence occurring during reversal of tidal flows. For both channels the main source of turbulence was tidal flow along the seabed, with the bottom current speed cubed, |Ub3|, providing a reasonable proxy for tidal mixing and prediction of dense water outflows from Shark Bay the majority of the time. Orientation and deeper water of Geographe Channel along the main axis of the longitudinal density gradient provided an explanation for the predominant outflow from the Bay’s northern entrance. These density-driven currents could potentially influence recruitment of commercially fished scallops and prawns through dispersal and flushing of larvae.

Authors: Xu Jia , Li Chao , Li Yiran , Lim CW , Zhu Zhiwen
Published: March 2018

In this paper, a kind of single-walled carbon nanotube nonlinear model is developed, and the strongly nonlinear dynamic characteristics of such carbon nanotubes subjected to random magnetic field are studied. The nonlocal effect of microstructure is considered based on the theory of nonlocal elasticity. The natural frequency of the strongly nonlinear dynamic system is obtained by the energy function method, the drift coefficient and the diffusion coefficient are verified. The stationary probability density function of the system dynamic response is given and the fractal boundary of the safe basin is provided. Theoretical analysis and numerical simulation show that stochastic resonance occurs when varying the random magnetic field intensity. The boundary of safe basin has fractal characteristics and the area of safe basin decreases when the intensity of the magnetic field permeability increases.

The purpose of this study is to investigate the moderating effect of technology configuration capability on the relationship between strategic flexibility and organizational performance through different stages of technological life cycle. Through the empirical research on the 439 Chinese high-tech organizations, it shows that a technological configuration capability has enhanced the effect of strategic flexibility to the organizational performance in the complex dynamic environment. However, the impact on the different stages of technological life cycle is different. In addition, this paper explored strategic flexibility on different stages of technological life cycle on the basis of empirical study.
The Nefarious Nexus of Noncoding RNAs in Cancer
Authors: Anastasiadou Eleni , Faggioni Alberto , Trivedi Pankaj , Slack Frank J.
Published: March 2018

The past decade has witnessed enormous progress, which has seen the noncoding RNAs (ncRNAs) turn from the so called dark matter RNA to critical functional molecules, influencing most physiological processes in development and disease contexts. Many ncRNAs interact with each other and are part of networks that influence the cell transcriptome and proteome and consequently the outcome of biological processes. The regulatory circuits controlled by ncRNAs have become increasingly more relevant in cancer. Further understanding of these complex network interactions and how ncRNAs are regulated, is paving the way for the identification of better therapeutic strategies in cancer.

Design and Diagnosis of Deviated Rod-Pumped Wells
Authors: Gibbs S. G.
Published: March 2018

Commonly used methods for design of rod pumping installations presume vertical wells. This paper introduces a wave equation methodology which applies to wells that are deviated, either intentionally or unintentionally. Restrictions on surface locations and interest in horizontal drilling are increasing the number of deviated wells needing to be designed. Together with long standing crooked hole problems, these are promising subjects for further study.

This paper describes a predictive method that applies to 3 dimensional problems. A study is made of a well deemed too crooked to pump and a procedure is presented for designing intentionally deviated wells. The relative friction effects of rod guides are discussed and the effect of borehole path on power consumption is treated. The concept of dogleg severity is examined and deemed inadequate as a measure of difficulty in pumping deviated wells. The type of errors that result when vertical hole diagnostic methods are applied to deviated holes is discussed. Finally a new formulation of the radius of curvature concept is derived together with techniques for deducing rod-tubing friction from dynamometer valve checks. Comparisons with actual measurements are included to demonstrate the validity of the methods.

It is concluded that deviated wells can be adequately designed with wave equation methods. Also it is seen that highly deviated wells can be produced with rod pumping equipment when care is taken to control the path of the borehole. This paper should be considered as a progress report since much remains to be learned about application of the technology.

Ukrainian Linguistics in Canada: Second Half of the Twentieth Century and Beyond
Authors: Hornjatkevyč Andrij
Published: March 2018

In Canada, linguistic research into the Ukrainian language has appeared in both scholarly periodicals and in book form. For practical reasons, however, only published books will be examined here. These publications may be grouped into three major categories: language instruction, lexicography, and theoretical study. Furthermore, international borders were and continue to be porous: the works of Canadian scholars have been published abroad, while books by American scholars have been published in Canada. Consequently, major textbooks and learning grammars, lexicographic works, and books on theoretical issues dealing with Ukrainian linguistics by Canadian linguists and by foreign scholars published in Canada will be examined here.

A One‐Dimensional Physically Based Approach to Predict Soil Profile Aeration Requirements
Authors: de Jong van Lier Quirijn , Pinheiro Everton Alves Rodrigues , Inforsato Leonardo
Published: March 2018

Core Ideas

A process‐based theory for predicting the minimum air‐filled porosity was developed.

The model allows analyzing sensitivity of aeration requirements to system parameters.

Common static air content values for entire soil profiles are shown to be flawed.

A minimum air‐filled porosity (βmin) is necessary to allow sufficient gas influx and efflux without restricting the aerobic activities of roots and microorganisms. Fixed values for βmin are commonly used in crop growth and hydrological models, thus relegating the physical process of gas flow. We developed a process‐based approach to estimate the minimum air‐filled porosity along the soil profile, assuming the excess of CO2 to trigger the onset of deficit aeration. The developed set of equations is based on Fick's law and mass conservation and includes root depth and pore‐space tortuosity for gas diffusivity, rate of gas production over depth and soil gaseous diffusivity. The developed theory allows prediction of gas concentrations and aeration status for different boundary conditions. The minimum air‐filled porosity was shown to be dependent on profile depth and soil type, and in this respect commonly used fixed values for entire soil profiles would be flawed. When considering the pressure heads corresponding to these minimum air‐filled porosity, results showed an even higher dependence of soil type.

What can we learn from a 500-year event? Experiences from urban drainage in Austria
Authors: Kleidorfer Manfred , Tscheikner-Gratl Franz , Vonach Tanja , Rauch Wolfgang
Published: March 2018

Urban drainage systems are designed to capture the runoff for a certain return period of a design rainfall event. Typically, numerical models are used, which are calibrated by comparing model response and measured system performance. The applicability of such models to predict the system behaviour under extreme events is unclear, as usually then no data are available. This paper describes the analysis of an extreme rainfall event in the year 2016. The event is characterized by a very short duration and very high rainfall intensities. The maximum-recorded rainfall peak was 47.1 mm rainfall within 10 min, which corresponds to a return period of 500 years. The event caused local flooding on streets, interruptions of traffic and damages in buildings. In order to improve the flood resilience of the city, the event was analysed with an existing 1D hydrodynamic model of the sewer system. Model results were compared to water level measurements in the drainage system and citizen observations of surface flooding (gathered from social media and citizen reports). Although the hydrodynamic model could reproduce water level measurements in parts of the system, the plausibility check using descriptive data showed that the model failed to predict flooding in some areas.

Published: March 2018

The potency of oil palm empty fruit bunches (OPEFB) fibers as one of the by-products of processing oil palm is increasing significantly so that proper management is needed in reducing environmental impact. One of the utilization of OPEFB fibers is as a substitution material in construction which usually the material is derived from non-renewable mining materials so that the number is increasingly limited. Therefore, it is necessary to study to know the performance of OPEFB fiber in making construction products especially concrete. In this case, the experiment was conducted using experimental method with variation of fiber addition by 0%, 10%, 15%, 20%, 25%, and 30%. Each specimen was tested by weight, slump value, compressive strength, tensile strength, elasticity and crack length. As the results, the variation of fibers addition by 10%, decrease of slump value is 7%, concrete weight is 3% and crack length is 8% while increase of the compressive strength is 2.7% and the modulus of elasticity is 33.3% but its tensile strength decreased insignificantly by 0.05% . Furthermore, the addition of fibers above 10% to 30% decreased compressive strength is still below 10% and tensile strength below 2% while the weight of concrete, slump value and crack length decreased. Therefore, the addition of 10% can replace the performance of concrete without fiber but the addition of above 10% can still be used on non-structural concrete.

On the chanting space and hymns that were sung in it. Searching for chanting-architectural connections in the middle ages
Authors: Peno Vesna , Obradovic Marija
Published: March 2018

The search for the unexplained interactions of domestic medieval liturgical
music and sacred architecture of the Moravian style has not been the subject
of interdisciplinary study so far. A reflection on the potential relationg
between church chanting and architecture is absent from the largest part of
the existing literature on the development of medieval sacral art. The
scarcity of written historical sources, and especially musical ones, made it
particularly difficult to define the connection between the chanting
circumstances and the changes in the architectural form of the late Byzantine
period, which is almost a standardized Moravian architectural form. The
earliest preserved bilingual - Greek-Slavic neumatic manuscripts, mentioning
both the names of the first famous Serbian medieval composers, and the more
or less well known late Byzantine musicians who had actively participated in
the earliest religious services of the Serbian Church, confirm that the
culmination of the chanting art in Serbia occured precisely at the turn of
the 15th century and then until the fall of Serbia under Turkish rule.
Comparing the available data, with a general insight into the migration flows
that led to the Byzantinization of Serbian culture in that period, showed
that after the reconciliation of the Serbian Patriarchate and the
Patriarchate of Constantinople, in 1374, the world-class building tradition
was adopted, which until then was sporadically seen on the Serbian soil. The
architectural form of the Moravian style would become recognizable by the
singing apses in the axis of the transept, in the middle of the already
adopted form of the inscribed cross from the early 14th century. Within the
framework of the overall church, political and cultural transformation that
was visible in Serbian society, the chanting practice of the Serbian Church,
or more precisely the greater affirmation of the liturgical art and the
increase in the number of the chanters, certainly had a share both in
acceptance and in the consistent implementation of the architectural
solutions of the Moravian style. Future research should focus on the holistic
analysis of the Moravian cultural heritage, in order to map the movement of
the known and unknown Serbian Greek melods and determine the scope of their
activity. The existing knowledge of the architectural features of the
Moravian sacred buildings will thus receive a significant addition, from the
liturgical and religious service in which each form of church art is
individually represented as part of a much more complex artistic ensemble
with which the Kingdom of Heaven on the Earth is iconized.
Preventive Use of a Resin-based Desensitizer Containing Glutaraldehyde on Tooth Sensitivity Caused by In-office Bleaching: A Randomized, Single-blind Clinical Trial
Authors: Diniz ACS , Lima SNL , Tavarez RRdJ , Borges AH , Pinto SCS , Tonetto MR , Loguercio AD , Bandéca MC
Published: March 2018

Objective:

To evaluate the risk and intensity of bleaching-induced tooth sensitivity (TS) after in-office bleaching following topical application of a resin-based glutaraldehyde desensitizer.

Methods:

Thirty-three patients were randomly assigned to the experimental (Gluma Desensitizer Liquid, Heraeus Kulzer, Hanau, Germany) and placebo groups. The placebo or Gluma Desensitizer Liquid was applied for one minute prior to application of an in-office bleaching gel. Bleaching was performed with 35% hydrogen peroxide gel (three applications × 15 minutes each) over two sessions, one week apart. The color of the anterior teeth was evaluated before and 21 days after treatment using the VITA Classical shade guide, Bleachedguide 3D, and Easyshade spectrophotometer. TS during and after the bleaching was recorded according to the visual analog (VAS) and numerical rating (NRS) scales. All data were submitted to statistical analysis (α=0.05).

Results:

There was no significant difference in absolute risk or intensity of TS between the two groups (risk and VAS, p=0.93 and 0.31, respectively; NRS, p≥0.45). At the end of the bleaching protocol, tooth whitening was observed in both groups, as evident from color change in shade guide units (ΔSGU, 4.1-7.1; both guides) and overall color change (ΔE, 7.4-9.3 units); however, there were no significant differences in whitening between the two groups (p>0.11).

Conclusion:

Gluma Desensitizer Liquid was not able to reduce the risk or intensity of TS. Bleaching efficacy was not affected by application of the desensitizer.

Do Nanofilled/Nanohybrid Composites Allow for Better Clinical Performance of Direct Restorations Than Traditional Microhybrid Composites? A Systematic Review
Authors: Angerame D , De Biasi M
Published: March 2018

This systematic review was carried out to assess the clinical effectiveness of nanofilled and nanohybrid composites used for direct restorations in comparison with microhybrid composites. The guidelines for the preferred reporting items for systematic reviews and meta-analyses were followed. A search of articles published from July 1996 to February 2017 was performed in PubMed, SciVerse Scopus, Latin American and Caribbean Health Sciences, the Scientific Electronic Library Online, and the Cochrane Library. The present review selected only randomized controlled trials comparing the clinical performance of a nanofilled or nanohybrid composite for direct restorations with that of a microhybrid composite. The research found 201 studies. Twenty-one articles fulfilled the criteria of the present review. However, the included studies were characterized by great methodological diversities. As a general trend, nanofilled and nanohybrid composites were found to be capable of clinical performance, marginal quality, and resistance to wear similar to that of traditional composites without showing improved surface characteristics. The risk of bias of included studies was judged unclear or high. The clinical performance of nanofilled/nanohybrid composites was found to be comparable to that of traditional composites in the posterior area. The data concerning anterior and cervical restorations were insufficient. With regard to the esthetic properties, there is a compelling need for studies on anterior teeth in which the operators are kept unaware of the restorative material. Nanofilled/nanohybrid composites seem to be a valid alternative to traditional microhybrid composites, and at the moment, there is low-level evidence attesting a lack of their superiority.
