Antibiotic Resistance Profile of Clinical Strains of Enterococci from Secondary/Persistent Endodontic Infections: What do We Know? A Systematic Review of Clinical Studies.

INTRODUCTION: Enterococcus faecalis is the most common enterococcal species associated with infective endocarditis and 1 of the most commonly detected bacteria in cases of secondary/persistent endodontic infection (SPEI). Antimicrobial resistance is a global public health concern. This review aimed to answer the following research question: "Is there a change in the antibiotic resistance profile in clinical strains of E. faecalis over the years?". P (population) - patients with SPEI, I (intervention) -endodontic retreatment, C (comparison) -not included, O (outcome) - profile of Enterococci resistance and susceptibility to systemic antibiotics used. METHODS: Two authors independently performed study selection, data extraction, and risk of bias assessment. The literature search was conducted using the following electronic databases: PubMed, Scopus, EMBASE, Web of Science, and Medline. Clinical studies in which Enterococci strains were isolated to assess their antimicrobial resistance were included. RESULTS: Eleven clinical trials were included. Overall, E. faecalis isolated from teeth with SPEI presented an intermediate resistance to 16 antibiotics. In recent years, E. faecalis showed a little resistance to amoxicillin (without clavulanate) and benzylpenicillin. Erythromycin and rifampicin presented an increase in the intermediate-resistance status between the first and the last studies. E. faecium presented intermediate-resistance results. CONCLUSION: The most effective drugs remain the combination of amoxicillin and clavulanate, followed by amoxicillin and benzylpenicillin. In patients allergic to penicillin derivatives, moxifloxacin and azithromycin may be indicated with caution. The antibiotics with the highest pattern of resistance against E. faecalis are clindamycin, gentamicin, metronidazole, and rifampicin and are therefore, contraindicated in cases of SPEI. Very few clinical studies using a microbiological approach in teeth with endodontic failure have been carried out to improve the efficacy of prophylactic regimens. However, as bacteria periodically develop resistance to the main drugs used, regular studies should be carried out on the action of these drugs in infection control.

Avaliação in silico da afinidade de drogas ao receptor TRPA1 como preditor para o manejo farmacológico da sensibilidade provocada pelo clareamento dentário / In silico assessment of drug affinity to the TRPA1 receptor as a predictor for the pharmacological management of sensitivity caused by tooth whitening

Introdução: Reduzir a sensibilidade do clareamento dental em consultório representa um desafio para os profissionais. Pesquisadores associaram o bloqueio do receptor de dor TRPA1 com a redução da sensibilidade ao clareamento. No entanto, a afinidade química dos analgésicos/anti-inflamatórios para o TRPA1 ainda precisa ser averiguada. Objetivo: Realizar uma triagem virtual de múltiplos medicamentos (analgésicos e antiinflamatórios) para verificar a afinidade química pelo receptor TRPA1. Metodologia: A estrutura cristalina das proteínas do receptor TRPA1 foi recuperada do Protein Data Bank. Os códigos SMILES dos ligantes foram extraídos do PubChem. A energia de ligação do complexo foi obtida em ∆G - kcal/mol pelo AutoDock Vina© e replicada nos servidores SwissDock©, Dockthor© e CbDock©. LigPlus© confirmou os sítios de ligação. Resultados: Apesar dos antagonistas dos receptores analisados apresentarem alta afinidade, codeína e dexametasona apresentaram regularidade em todos os servidores, mesmo apresentando valores de energia de ligação de -7,9 kcal/mol para codeína e -8,1 kcal/mol para dexametasona. Conclusão: A codeína e a dexametasona podem ser drogas potenciais para controlar a sensibilidade ao clareamento dental caso atinjam o receptor TRPA1 da polpa dentária (AU).

Introduction: Reducing in-office tooth bleaching sensitivity represents a challenge for professionals. Researchers have associated the block of the pain receptor TRPA1 with reducing bleaching sensitivity. However, the chemical affinity of analgesic/antiinflammatory drugs to the TRPA1 needs to be verified. Objective: To perform a virtual screening of multiple drugs (analgesic and anti-inflammatory drugs) to verify chemical affinity for the TRPA1 receptor. Methodology: The crystal structure of the TRPA1 receptor proteins was retrieved from the Protein Data Bank. The SMILES codes of the ligands were extracted from PubChem. The binding energy of the complex was obtained in ∆G - kcal/mol by AutoDock Vina© and replicated in the webservers SwissDock©, Dockthor©, and CbDock©. LigPlus© confirmed the binding sites. Results: Although the receptor antagonists analyzed showed high affinity, codeine and dexamethasone showed regularity among all servers, even showing binding energy values of -7.9 kcal/mol for codeine and -8.1 kcal/mol for dexamethasone. Conclusion: Codeine and dexamethasone may be potential drugs to manage tooth bleaching sensitivity if they reach the dental pulp TRPA1 receptor (AU).

Functional Ability of Dental Materials After Inclusion of Nanocarriers Containing Functional Substances: A Systematic Review.

BACKGROUND: Nanocarriers are nanoparticles used to transport functional substances. OBJECTIVE: This study aimed to perform a systematic review analyzing the functional ability of dental materials after the inclusion of nanocarriers containing functional substances. MATERIALS AND METHODS: We searched PubMed, Web of Science, EMBASE, SciELO, and Science Direct from (02/03/21) to (02/06/21) without restriction on the year of publication. We included studies evaluating the incorporation of Chitosan, PEG-PCL (poly(ethylene glycol)-poly(ε-caprolactone), PLGA (poly(lactic-co-glycolic acid), and mesoporous silica into dental materials. We analyzed the risk of bias with CRIS guidelines and consolidated all analyses using Microsoft Office Excel. RESULTS: In total, we found 656 studies and included 11. The articles investigated materials to eliminate microorganisms, interference with materials' mechanical properties, elution of remineralizing substances, and reduction of oral anesthetic toxicity. Chitosan and mesoporous silica were the most prevalent nanocarriers. Among all properties, the antibacterial activity was the most analyzed. The functional ability of dental materials provided by all nanocarriers improved. CONCLUSION: The use of nanocarriers may be a useful way to produce dental materials with improved functional abilities. We registered this manuscript in the Open Science Framework platform - DOI 10.17605/OSF.IO/RP5XK, available at https://osf.io/qg49x.

The combined use of systemic analgesic/anti-inflammatory drugs and a bioactive topical desensitizer for reduced in-office bleaching sensitivity without jeopardizing the hydrogen peroxide efficacy: a randomized, triple blinded, split-mouth clinical trial.

OBJECTIVE: To evaluate the effect of combined systemic administration of paracetamol 500 mg/codeine phosphate 30 mg (PACO) and postoperative topical application of a bioactive desensitizer on in-office bleaching sensitivity and tooth color change. MATERIALS AND METHODS: A randomized, triple-blind, split-mouth clinical trial was conducted. Forty volunteers ingested PACO (n = 20) or placebo (PLA) (n = 20). Their left/right hemiarches received topical application of a bioactive desensitizer [Nano-P™(NP)] and prophylactic paste (PAS), generating four treatment approaches: PACO/NP, PACO/PAS, PLA/NP, and PLA/PAS. Two bleaching sessions (35% hydrogen peroxide) were performed, and the PAS/NP were applied after the procedure. Sensitivity was obtained since the first bleaching session up to 7 days post-bleaching. The color change was evaluated using CIEDE2000 and whiteness index parameters up to 7 days post-bleaching. Data were analyzed using one- and two-way ANOVA/Tukey post hoc tests (p < 0.05). RESULTS: The PLA/PAS showed a sensitivity average of at least two times higher than the PACO/NP. The treatment approaches promoted statistically similar bleaching patterns (p > 0.05). CONCLUSION: The combined approach of systemic administration of PACO and postoperative topical application of NP reduced the level of in-office bleaching sensitivity without jeopardizing hydrogen peroxide efficacy. CLINICAL RELEVANCE: Professionals can adopt the combined approach of systemic administration of analgesic/anti-inflammatory drugs and topical application of a bioactive desensitizer for decreased bleaching sensitivity caused by 35% hydrogen peroxide in-office.

Dental workers in front-line of COVID-19: an in silico evaluation targeting their prevention.

OBJECTIVE: SARS-CoV-2 has high human-human transmission rate. The aerosols and saliva droplets are the main contamination source. Thus, it is crucial to point out that dental practitioners become a high-risk group of contagion by SARS-CoV-2. Based on this, protocols have been recommended to avoid cross-contamination during dental care; however, appropriate evidence has not yet been established. Our study sought to make a screening, by in silico analysis, of the potential of mouth rinses used in dental practices to prevent the dental workers' contamination by SARS-CoV-2. METHODOLOGY: Multiple sequence comparisons and construction of the phylogenetic tree were conducted using the FASTA code. Therefore, molecular docking investigation between SARS-CoV-2 proteins (Main Protease, Spike Glycoprotein, Non-structure Protein, and Papain-like Protease) and molecules used in dental practices (chlorhexidine digluconate, hydrogen peroxide, cetylpyridinium chloride, povidone-iodine, gallic acid, ß-cyclodextrin, catechin, and quercetin) was performed using AutoDock Vina. Moreover, 2D interactions of the complex protein-ligand structure were analyzed by Ligplot+. RESULTS: The obtained results showed a remarkable affinity between SARS-CoV-2 proteins and all tested compounds. The chlorhexidine digluconate, catechin, and quercetin presented a higher affinity with SARS-CoV-2. CONCLUSIONS: The overall results allowed us to suggest that chlorhexidine is the most suitable active compound in reducing the SARS-CoV-2 salivary load due to its better binding energy. However, in vivo studies should be conducted to confirm their clinical use.

Relationship of Porphyromonas gingivalis and Alzheimer's disease: a systematic review of pre-clinical studies.

OBJECTIVES: This study aimed to analyze the following PICO question: Are animals infected with Porphyromonas gingivalis (P. gingivalis) or bacterial lipopolysaccharide (Pg-LPS) more affected by neurodegeneration, similar to the pathogenesis generated by Alzheimer's disease (AD), compared with non-infected animals? METHODS: Databases PubMed, Lilacs, SciELO, Science Direct, Scopus, Web of Science, and Cochrane were searched for pre-clinical in vivo studies in which mice were infected with P. gingivalis or received Pg-LPS, in order to assess the brain tissue and cognitive impairment. No limit for date or publication language was imposed and this study was registered at the International Prospective Register of Systematic Reviews (PROSPERO), with nine articles included. Syrcle's protocol was used to evaluate bias in the selected studies. RESULTS: Nine articles were included. Infection by P. gingivalis or the administration of Pg-LPS increased the production of the inflammatory mediators, TNF-α (tumor necrosis factor-alpha), IL-6 (interleukin-6), and IL-1ß (interleukin-1beta), augmented Aß (amyloid beta) production, and activated the complement system, causing inflammation, brain tissue degeneration, and cognitive impairment, consistent with the damage in AD. CONCLUSIONS: Infection by P. gingivalis and Pg-LPS administration appears to be in relation with the pathogenesis of AD by activating the complement cascade, increasing Aß production and augmenting pro-inflammatory cytokine expression, causing age-dependent brain inflammation, neuroinflammation, and neurodegeneration. CLINICAL RELEVANCE: Taking into account the importance of holistic treatment in the dental office, this study focuses on identifying highly prevalent oral diseases, such as periodontal disease, as risk factors for the aggravation of degenerative diseases in the elderly population.

Clinical and self-perceived oral health assessment of elderly residents in urban, rural, and institutionalized communities.

OBJECTIVES: This study aims to evaluate the self-perception of oral health according to the physical, psychosocial and pain/discomfort dimensions related to clinical conditions and orofacial pain of elderly people living in three different environments. METHODS: This was an observational, cross-sectional, quantitative study with a population-based approach and nonprobabilistic convenience sampling that included 81 elderly people: 27 resided in institutional homes for elderly individuals, 27 resided in an urban area and 27 resided in a rural area in the interior of Paraíba (PB) in northeastern Brazil. RESULTS: The Geriatric Oral Health Assessment Index (GOHAI) was used to assess self-perception of oral health, while the Questionnaire for Screening of Patients with Temporomandibular Disorders (QST/TMD) was used to assess the influences of orofacial pain and the biofilm indexes of teeth and prostheses. There was a statistically significant difference in the GOHAI scores among the places of residence, with the worst values associated with the rural area. According to the QST/TMD, the majority of individuals were affected by TMDs, with statistical differences for both sex and income. CONCLUSION: The biofilm analysis showed a higher incidence of clinical conditions in the rural population. The place of residence also influenced self-perception and the clinical oral health condition of elderly people; the rural population presented the worst results.

Planejamento para famílias homoafetivas: releitura da saúde pública brasileira / Planning for homoaffective families: a re-reading of Brazilian public health / Planificación para familias homoafectivas: relectura de la salud pública brasileña

Resumo Ao longo das últimas décadas, o conceito de família passou por muitas mudanças, divorciando-se do modelo nuclear tradicional. Embora a Constituição Federal tenha avançado quanto ao reconhecimento de novos núcleos familiares, ainda se omite na união homoafetiva, privando-a em termos de garantias e direitos. O objetivo deste artigo foi apontar a inexistência de preparação de estudantes e profissionais para lidar com casais homoafetivos e suas famílias. Trata-se de revisão narrativa respaldada por obras doutrinárias, legislação nacional pertinente, jurisprudência e documentos eletrônicos, como leis e normativas, que serviram de base para a elaboração do artigo científico. Com os avanços da sociedade e algumas recentes resoluções, hoje a união homoafetiva pode gozar de direitos semelhantes aos de casais heterossexuais quanto à reprodução medicamente assistida.

Abstract The concept of family has undergone many changes over the past decades, distancing itself from the traditional nuclear model. Although the Brazilian Federal Constitution has advanced in the recognition of new family nuclei, the homoaffective union is still omitted, depriving it of guarantees and rights. The aim of the present paper is to call attention to the lack of an academic and professional training to deal with homoaffective couples. It is a narrative review carried out on doctrinal works, pertinent national legislation, jurisprudence and electronic documents such as laws and regulations which served as the basis for the elaboration of this scientific article. With the advances in society in recognizing the homoaffective union as a part of civil society, being able to enjoy similar rights to those of heterosexual couples concerning reproduction medically assisted.

Retalho reposicionado coronalmente com a finalidade de recobrimento radicular / Coronally advanced flap with the purpose of root coverage

Introdução: a recessão gengival é caracterizada pelo desnudamento parcial da superfície radicular decorrente da migração apical da gengiva marginal e pela degradação do mecanismo de inserção gengival sobre o elemento dentário. Objetivo: descrever um caso clínico de retalho reposicionado coronalmente com a finalidade de recobrimento radicular em paciente que apresentava recessão gengival Classe I de Miller nos elementos dentários 23 e 24. Materiais e Métodos: O presente estudo contou com a participação de um paciente que queixava-se de hipersensibilidade dentinária, quando aplicado o estímulo térmico, e de insatisfação estética devido à exposição radicular visível ao sorrir e durante o ato de conversação. Foi traçado um plano de tratamento para o recobrimento radicular através de cirurgia de retalho reposicionado de forma coronal, seguido de encaminhamento para a realização de tratamento ortodôntico, já que o paciente possuía oclusão traumática na região acometida pela recessão gengival, decorrente da presença de contato prematuro. Resultados e Discussão: com a técnica empregada, foi possível restabelecer a normalidade estética, prevenir o acúmulo de biofilme dental, devido à maior facilidade de higienização da região cervical, permitindo também a redução da hipersensibilidade dentinária, anteriormente relatada pelo paciente. Conclusão: a técnica cirúrgica de retalho coronal, utilizada para a resolução deste caso, mostrou-se uma eficiente forma de tratamento, pois apresentou resultados satisfatórios levando-se em consideração a previsibilidade de recobrimento da superfície radicular para esta técnica, que é de 70 a 99% da área exposta, devolvendo assim, função ao elemento tratado.

Introduction: the gingival recession is characterized by the partial denudation of the root surface resulting from the apical migration of the marginal gingiva and by the degradation of the gingival insertion mechanism on the dental element. Objective: we present a clinical report of a coronally advanced flap with the purpose of root coverage in a patient who presented gingival recession Miller Class I in the elements 23 and 24. Material and Method: the patient complained of dental hipersensibility when a thermal stimulus was applied and also a aesthetics dissatisfaction due to a visible root exposure to smile and during the act of conservation. A treatment plan was traced for the root coverage by a coronally repositioned flat, followed by a orthodontic treatment due to premature contact. Results: with the technique employed, it was possible to restore aesthetic normality, to prevent the accumulation of dental biofilm due to an ease of cleaning the cervical region, also allowing the reduction of dental hipersensibility, previously reported by the patient. Conclusion: it's possible to claim that the surgical technique of coronal flap used to the resolution of this case is an efficient form of treatment taking into account the root surface coverage for this technique, which is of 70 to 99% of the exposure area, returning to the treated element its function.

Epithelial odontogenic tumors: analysis of 156 cases in a Brazilian population / Tumores odontogénicos epiteliales: análisis de 156 casos en una población brasileña

The objective of this study was to determine the distribution of epithelial odontogenic tumors diagnosed histologically in a period of 41 years in a Brazilian population according to age, gender, site affected and compare these data with previously reported studies from other countries. Data of epithelial odontogenic tumors diagnosed were collected from the files of the Oral Pathology Laboratory of Federal University of Rio Grande do Norte, Natal, RN, Brazil, and entered in a standardized form for later comparisons. Clini-cal features obtained from the patient records and microscope slides were reviewed according to the 1992 World Health Organization classification. A total 156 epithelial odontogenic tumor were reported. Of these, all of them were benign. Ameloblastoma was the most frequent type (85.9 %), followed by adenomatoid odontogenic tumor (10.9 %) and calcifying epithelial odontogenic tumor (3.2 %). The mean age of the patients was 38 years, with a wide range (11­80 years). The posterior region of mandible was the anatomic site most frequently affected by this disease, and no significant differences were found between sexes in the diagnosis of odontogenic tumors. A marked geographic variation in the relative incidences of various epithelial odontogenic tumors was found. It was particularly notable in ameloblastomas and adenomatoid odontogenic tumors, with the incidences observed in the present study being similar, sometimes different to earlier studies in others parts of the world.

El objetivo fue determinar la distribución de los tumores odontogénicos epiteliales diagnosticados histológicamente en un período de 41 años en una población brasileña según edad, sexo y la zona afectada y comparar estos datos con estudios anteriores de otros países. Los datos de los tumores odontogénicos epiteliales diagnosticados fueron obtenidos de los archivos del Laboratorio de Patología Oral de la Universidad Federal de Rio Grande do Norte, Natal, RN, Brasil, e introducidos en un formulario estandarizado para comparaciones futuras. Las características clínicas obtenidas a partir de los registros de los pacientes y los portaobjetos de microscopio fueron revisados de acuerdo a la clasificación de la Organización Mundial de la Salud 1992. Se informó de un total de 156 tumores epiteliales odontogénicas. De estos, todos eran benignos. Ameloblastoma fue el tipo más frecuente (85,9 %), seguido por el tumor odontogénico adenomatoide (10,9 %) y el tumor odontogénico epitelial calcificante (3,2 %). La edad media de los pacientes fue de 38 años, con un rango amplio (11­80 años). La región posterior de la mandíbula era el sitio anatómico más afectado por esta enfermedad, y no se encontraron diferencias significativas entre sexos en el diagnóstico de los tumores odontogénicos. Se encontró una marcada variación geográfica en las incidencias relativas de diversos tumores odontogénicos epiteliales. Fue particularmente notable en ameloblastomas y tumores odontogénicos adenomatoide, con las incidencias observadas en este estudio siendo a veces similares, y a veces diferentes de los estudios anteriores en otras partes del mundo.
