O uso da tomografia computadorizada de feixe cônico como um método eficaz para avaliação de fraturas radiculares: Uma revisão da literatura

  The occurrence of dental fractures is characterized by the rupture of dental tissue, resulting in a visible line of discontinuity that can manifest itself in different orientations. The objective of this study is to seek an answer, through the literature, whether cone beam computed tomography (CBCT) can be used to diagnose root fractures (RF). To answer this question, an extensive literature review was carried out using electronic databases. Search terms included “cone beam computed tomography,” “endodontics,” “root fracture,” and their corresponding English equivalents. Only articles relevant to the topic and published between 2015 and 2024 were selected. The results indicate that CBCT is the most effective imaging technique for detecting RF, with an ideal size, producing ideal results. However, it is essential that the Dental Surgeon (DC) acquires knowledge about the examination process to accurately interpret the results and determine when it is necessary to request a CT scan.  A ocorrência de fraturas dentárias é caracterizada pela ruptura do tecido dentário, resultando em uma linha visível de descontinuidade que pode se manifestar em diversas orientações. O objetivo deste estudo é buscar responder, por meio da literatura, se a  tomografia computadorizada de feixe cônico (TCFC) pode ser utilizada para o diagnóstico de fraturas radiculares (FR). Para responder a esta questão, foi realizada uma extensa revisão da literatura utilizando bases de dados eletrônicos. Os termos de pesquisa incluíram “tomografia computadorizada de feixe cônico”, “endodontia”, “fratura radicular” e seus equivalentes em inglês correspondente. Foram selecionados apenas artigos relevantes ao tema e publicados entre 2015 e 2024. Os resultados indicam que o TCFC é a técnica de imagem mais eficaz para detectar FR, com um tamanho ideal, produzindo resultados ideais. Porém, é fundamental que o Cirurgião-Dentista (CD) adquira conhecimento sobre o processo do exame para interpretar com precisão os resultados e determinar quando é necessário solicitar uma tomografia computadorizada

As várias fontes dessas células, inserem a área odontológica em um cenário de grandes avanços científicos, que serão mais palpáveis com o aumento dos estudos na esfera da bioengenharia tecidual, a fim de promover a regeneração do tecido dental, em específico na endodontia, periodontia, cirurgia e traumatologia bucomaxilofacial. Entretanto, a regeneração destes tecidos não é tão simples, já que o seu desenvolvimento é determinado através de interações complexas envolvendo inúmeros fatores de crescimento, além da diferenciação celular que está ligada às mudanças morfológicas no decorrer da formação do germe dentário. Os dentes são apontados como excelentes fontes de células-tronco e de suma importância, pois têm proporcionado grandes experimentos por seu fácil acesso, acreditando-se que futuramente o uso destas células represente um grande avanço nos tratamentos odontológicos

LC-MS Analysis and Antifungal Activity of <i>Turnera subulata</i> Sm.

Fungi of the Candida genus are responsible for invasive candidiasis, which affects people all over the world and has high mortality rates. This is due to their virulence factors, which give them great resistance and pathogenicity. In addition, the emergence of multidrug-resistant strains makes it difficult to treat these infections. In this way, natural products have emerged as an alternative to standard drugs, where plants known for their medicinal properties such as Turnera subulata become attractive to research. The present work aimed to analyze the ethanol extract of Turnera subulata leaves against standard strains of Candida albicans, Candida krusei and Candida tropicalis using broth microdilution techniques. The identification of the compounds in T. subulata leaves by LC-MS revealed the presence of a wide variety of substances such as carboxylic acids and terpenes, with flavonoids and fatty acids being more evident. The antifungal assays showed that the extract was not able to inhibit the growth of the tested strains at concentrations with a clinical relevance. However, at higher concentrations, it was able to inhibit the fungal dimorphism of C. albicans and C. tropicalis. It is possible that the T. subulata extract has potential as an inhibitor of fungal virulence factors without affecting the cell viability. Further research should be carried out in order to assess its inhibitory potential for other fungal virulence factors

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
