Impacção dentária do tipo “Kissing Molars”: uma revisão narrativa da literatura/ "Kissing Molars" Dental Impaction: a narrative review of the literature

“Kissing Molars” (KMs) é um tipo incomum de impacção dentária, definido como molares inclusos com íntimo contato das superfícies oclusais em um único espaço folicular e raízes apontando em direções opostas. Este estudo teve como objetivo investigar e descrever, por meio de uma revisão narrativa da literatura, evidências sobre KMs, agrupando informações de etiologia, classificação, prevalência, diagnóstico, tratamento e complicações desta rara impacção. Para isso, realizou-se uma pesquisa por publicações em 7 bases de dados eletrônicas, utilizando as palavras chaves: "kissing molars" OR "kissing molar" OR "kiss of molars" OR "kissing teeth" OR "rosetting of molars" OR "rosetting of molar". Além disso, foi efetuada busca manual por citações nas publicações inicialmente selecionadas. Estudos com pelo menos um caso clínico de KMs que descrevessem características clínicas, diagnósticas e/ou terapêuticas foram incluídos. Foram encontrados 179 artigos segundo os critérios pré-estabelecidos para coleta de dados, e apenas 37 foram incluídos nesta revisão. Os resultados mostraram que um total de 64 casos de KMs são descritos na literatura, mas há poucas informações disponíveis sobre prevalência, o fator etiológico permanece desconhecido e não há diretrizes definidas para tratamento

Manejo de cárie radicular: um guia para o dentista brasileiro baseado na tradução e adaptação cultural do consenso internacional/ORCA E EFCD

Aim: Root caries are a problem in modern dentistry, but the lack of guidelines regarding their management is notable. We aim to develop and adapt a guide based on the translation of the recommendations of the international consensus as outlined by the European Organization for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD) for clinical decision-making in the intervention of the caries process in the elderly, with a focus on root caries. Materials and methods: The protocol for translating the recommendations of the international consensus consisted of the following steps: (1) initial translation, (2) synthesis of the translation, (3) back-translation, (4) review by an expert committee with cultural adaptation. Based on the translation, a guide was developed with guidelines for the treatment of root caries in Brazil. Results: To prevent new lesions, daily brushing with toothpaste >1,500ppm/F is recommended. Toothpaste with 5,000ppm/F or varnishes (>20,000ppm/F) may be recommended to paralyze active root lesions and for prevention in elderly people with high susceptibility to root caries, and Silver Diamine Fluoride (>30%) to paralyze active lesions. Direct invasive interventions are indicated depending on the clinical situation. Discussion: There is a lack of interest in primary studies on treatments for root caries, thus creating a gap in relation to its management, which is reflected by the level of evidence detected in the consensus. Conclusion: Clinical guidelines are important to reduce the gap between research and clinical practice. This translation into Portuguese will facilitate access by Brazilian dentists to the consolidated evidence gathered to date for the management of root caries.Objetivo: A cárie radicular é um problema da Odontologia moderna, porém é notável a falta de diretrizes sobre o seu manejo. Objetivamos elaborar e adaptar um guia a partir da tradução das recomendações do consenso internacional European Organization for Caries Research (ORCA) e European Federation of Conservative Dentistry (EFCD) para as tomadas de decisão clínica na intervenção do processo de cárie na pessoa idosa, com foco na cárie radicular. Materiais e métodos: O protocolo de tradução das recomendações do consenso internacional consistiu nas etapas: (1) tradução inicial, (2) síntese da tradução, (3) retradução, (4) revisão por comitê de especialistas, com adaptação cultural. A partir da tradução, foi desenvolvido um guia com diretrizes para tratamento de cárie radicular no Brasil. Resultados: Para prevenção de novas lesões é recomendada a escovação diária com dentifrício >1.500ppm/F. Dentifrícios com 5.000ppm/F ou vernizes (>20.000ppm/F) podem ser indicados para paralisar lesões radiculares ativas e para prevenção em pessoas idosas com alta suscetibilidade à cárie radicular, e o Diamino Fluoreto de Prata (>30%) para paralisar lesões ativas. Intervenções invasivas diretas são indicadas dependendo da situação clínica. Discussão: Nota-se uma falta de interesse em estudos primários sobre tratamentos para cárie radicular, criando assim uma lacuna em relação ao seu manejo, que reflete no nível de evidência detectado pelo consenso. Conclusão: Guias clínicos são importantes para reduzir a lacuna entre a pesquisa e a prática clínica. Essa tradução para o português facilitará o acesso dos dentistas brasileiros em relação a evidência consolidada até o momento para o manejo de cárie radicular

Effect of low-intensity therapeutic ultrasound on wound healing in rats subjected to third-degree burns

PURPOSE: To determine the effectiveness of low-intensity therapeutic ultrasound (LITUS) on wound healing in rats with third-degree burns. METHODS: Twenty rats were divided into the Control Group that comprised four rats without third-degree burns that did not undergo LITUS, the Burned Group (BG), comprising eight rats with third-degree burns that did not undergo LITUS, and the Burned with Treatment Group (BTG), comprising eight rats with third-degree burns that were administered LITUS. LITUS began 24 h after injury and involved daily applications for 8 min at 0.1 W/cm2 for 14 days. RESULTS: The BTG lost less weight than the BG (Q=2.75; p<0.05). No visible differences were apparent among the groups' lesions on day 4. By the end of treatment, wound healing was more evident in the BTG. No statistically significant differences were found between the BG and the BTG in relation to the parameters measured using the histological changes in burn wound healing scoring system. CONCLUSION: The LITUS protocol applied to the animals with third-degree burns accelerated the formation of fibrin-leukocyte crusts and significantly reduced weight loss. However, burn wound healing was not accelerated

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
