The effect of biopolymer gel derived from sugarcane on healing of traumatic oral ulcers: an experimental study

Purpose: The extracellular polysaccharide (EPS) is produced by the bacterium Zoogloea sp. and plays a positive role in tissue repair. The purpose of this study was to clinically and histologically compare the effects of EPS in the healing of traumatic oral ulcers in rats with the effects of triamcinolone. Methods: Ulcers were induced in the oral mucous of 45 male Wistar rats, divided into three groups: control group, treated with triamcinolone, and treated with biopolymer gel. In the clinical evaluation, we considered the weight variation of the animals and the size of the lesion area, at baseline and on treatment days 1, 3 and 7. The histological parameters evaluated were the type and intensity of the inflammatory infiltration, the presence of necrosis and foreign body granuloma and the degree of re-epithelialization of the lesion. Results: The reduction of the lesion area was greater in the animals treated with EPS, with no difference in the intensity of the inflammatory infiltration between the groups on days 3 and 7 of treatment. Conclusions: The results suggest that topical application of EPS in traumatic oral ulcers of rats promotes faster repair than triamcinolone ointment, without increasing the intensity of inflammatory infiltration under the lesion.

Morphological variations of the labial frenum, type of attachment and presence of diastemas: integrative review / Variações morfológicas do freio labial, tipo de inserção e presença de diastemas: revisão integrativa

ABSTRACT Objective: The aim of the present literature review was to compile data on the frequency of morphological and attachment types of the upper and lower labial frenum in different populations and investigate the association between the attachment level of the upper labial frenum and the occurrence of diastemas. Methods: Searches were conducted between May and June 2021 in the Medline (via Ovid), Google Scholar and CAPES databases. Thirty-eight studies that evaluated frenum morphology, frenum morphology and attachment or frenum morphology, attachment and the occurrence of diastemas were selected for the extraction of data. Results: Based on the data compiled in this review, the most common morphological and attachment types were labial frenum normale and mucosal attachment. The papillary and papilla penetrating types of attachment were more associated with the occurrence of diastemas. Conclusion: Longitudinal studies are needed to investigate this correlation in children and adults.

RESUMO Objetivo: O objetivo dessa revisão de literatura é compilar dados referentes a frequência de tipos morfológicos e de inserção do freio labial superior ou inferior, em diferentes populações, além de avaliar a relação entre o nível de inserção do freio labial superior e a ocorrência de diastemas. Métodos: Foram consultadas as bases de dados Medline (via Ovid), o Google acadêmico e o portal periódicos CAPES. A pesquisa foi realizada no período compreendido entre os meses de maio e junho de 2021. Foram selecionados para a extração de dados 35 estudos, que avaliação a morfologia do freio ou morfologia e inserção ou morfologia, inserção e presença de diastemas. Resultados: A partir dos dados compilados por essa revisão, foi possível estabelecer que os tipos morfológicos e de inserção mais comuns foram freio labial simples e inserção em mucosa. Com relação ao tipo de inserção e a ocorrência de diastemas, os tipos papilar e papilar penetrante foram os mais associados à sua ocorrência. Conclusão: Há necessidade de estudos longitudinais que avaliem essa correlação em crianças e populações adultas.

Cuidado integrado do paciente periodontal diabético tipo 2 na Atenção Básica: revisão scoping / Integrated care of type 2 diabetic periodontal patient in Primary Care: scoping review

Resumo Objetivo: Investigar a existência de protocolos validados para o cuidado do paciente periodontal com diabetes mellitus tipo 2 (DM2), a fim de transformá-los em recomendações para ações que poderiam ser desenvolvidas no âmbito da atenção primária em saúde. Métodos: Foi realizada uma revisão scoping, para a qual foi revista a literatura publicada de 2012 a 2019 nas bases de dados PubMed, Scielo, LILACS, Web of Science e Scopus, nas línguas inglesa, espanhola e portuguesa. Resultados: Foram encontrados 236 títulos, dos quais 37 foram selecionados para leitura integral. Os artigos foram agrupados em quatro eixos, de acordo com a similaridade de abordagens para o assunto tratado. Conclusão: Recomenda-se desenvolver estudos que investiguem o impacto da integração da assistência médica e odontológica no controle glicêmico de pacientes com DM2 e validem os protocolos clínicos para a assistência multidisciplinar desse paciente no contexto da atenção primária em saúde.

Abstract Objective: To investigate the existence of validated protocols for the care of periodontal patients with type 2 diabetes mellitus (DM2), to transform them into recommendations for actions that could be developed within the scope of primary health care. Methods: A scoping review was carried out, and the literature published from 2012 to 2019 was reviewed in the PubMed, Scielo, LILACS, Web of Science and Scopus databases, in English, Spanish and Portuguese. Results: 236 titles were found, of which 37 were selected for full reading. The articles were grouped into four axes, according to the similarity of approaches to the subject addressed. Conclusion: Studies investigating the impact of the integration of medical and dental care in the glycemic control of patients with DM2 and validating the clinical protocols for multidisciplinary care for this patient in the context of primary health care should be carried out.
