Laser de diodo de alta potência como coadjuvante ao tratamento mecânico não cirúrgico da periodontite: revisão integrativa para definição de um protocolo clínico / High power diode laser as a coadjuvant to the non-surgical mechanical treatment of periodontitis: integrative review for the definition of a clinical protocol

Introdução: O laser de diodo de alta potência pode potencializar os efeitos clínicos e microbiológicos da raspagem e alisamento radicular no tratamento da periodontite, principalmente nos sítios profundos e de difícil acesso pelas curetas. Objetivo: revisar os protocolos clínicos de pesquisas que utilizaram o laser de diodo de alta potência como terapia coadjuvante à raspagem e alisamento radicular no tratamento da periodontite. Métodos: Utilizando a estratégia PICO (População, Intervenção, Controle e Resultado) para a realização de buscas cruzando palavras chaves, em plataformas virtuais e gratuitas, entre 2015 e 2020. Foram coletados ensaios clínicos abordando o tema, dos quais alguns foram selecionados através da aplicação de critérios de inclusão e exclusão e em seguida apresentados em tabela contendo as suas principais informações. Resultados: Com a aplicação dos critérios de inclusão e exclusão obtivemos 5 ensaios clínicos randomizados para análise. Em três deles a aplicação adjunta de laser resultou em diferenças benéficas estatisticamente relevantes, enquanto nos outros dois, essa diferença foi observada apenas clinicamente. Foi observado efeitos mais significativos com a associação da aplicação do laser de diodo ao tratamento convencional, sem efeitos adversos ao paciente. Conclusão: Devido a heterogeneidade das pesquisas encontradas, especificamente com relação ao diâmetro da fibra, comprimento de onda, potência e intensidade do laser, torna-se difícil a definição de um protocolo padrão para o tratamento da periodontite. No entanto, alguns parâmetros utilizados parecem estar definidos, tais como: potência variando de 1 a 3 W, fibra de 300 ou 400 ?m, tempo de irradiação de 20 a 30 segundo por sítio com movimentação da fibra, na bolsa periodontal, no sentido ápico-coronário.

Relação entre doenças sistêmicas e manifestações periodontais: um enfoque em grupos de risco da COVID-19 / Relationship between systemic diseases and periodontal manifestations: a focus on COVID-19 risk groups

Objetivo: avaliar na literatura a relação entre algumas condições sistêmicas e a doença periodontal, enfocando em alguns grupos de risco à infecção pelo novo coronavírus. Métodos: utilizou-se artigos publicados entre os anos de 2010 e 2020 nos bancos de dados online PubMed (National Libary of Medicine) e Science Direct, usando descritores e termos Mesh organizados em lógica booleana: “periodontal diseases” OR “Periodontitis” OR “ Gingivitis” em associação com "Asthma”, "Diabetes mellitus", “Renal insufficiency chronic” e "Heart diseases”. Resultados: Mediante a análise dos estudos elegíveis, observou-se que doenças cardiovasculares, diabetes mellitus, doença renal crônica e asma estão relacionadas à doença periodontal, podendo esta, agravar as condições supracitadas. Uma vez que os pacientes acometidos por essas condições sistêmicas estão incluídos no grupo de risco à contaminação pelo SARS-CoV-2, é substancial que o cirurgião-dentista juntamente com uma equipe multiprofissional tenha conhecimento acerca disso para que medidas que evitem possíveis agravamentos no quadro respiratório sejam adotadas

The effectiveness of high-power diode laser as an adjunct to mechanical instrumentation of deep pockets in a patient with generalized, stage III, grade C periodontitis

ABSTRACT Periodontitis is an inflammatory clinical condition caused by dysbiotic biofilm that results in progressive destruction of periodontal attachment and can lead to tooth loss if left untreated. Objective: To evaluate the clinical efficacy of high-power diode laser as an adjunct to mechanical instrumentation in periodontal pockets of a patient with generalized, stage III, grade C periodontitis. Methods: 126 sites of a patient were examined at the Clinical Research Laboratory (LabClin) of the Federal University of Campina Grande (UFCG), where the parameters of probing depth (PD), clinical attachment level (CAL) and bleeding on probing (BoP) were evaluated at the beginning of the study and after 3 and 6 months of basic therapy. All sites received non-surgical periodontal treatment which corresponds to scaling and root planing (SRP) and coronary polishing. The deep periodontal pockets with PD ≥ 5 mm, received the adjuvant therapy with diode laser light. Results: There was a significant improvement of periodontal parameters of PD, CAL and BoP in all treated sites. In those with PD ≥ 5 mm, the results were similar, with statistically significant reduction of PD, CAL and BoP before and after treatment. After 6 months, all periodontal pockets with PD ≥ 5mm were reduced to values lower than 3. Conclusion: The irradiation of deep pockets with high-power diode laser proved to be effective as adjuvant therapy to SRP in patients with generalized, stage III, degree C periodontitis

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.

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set.
