1. Management of periapical lesion with persistent exsudate
Resumo Este relato de caso descreve o tratamento e acompanhamento de um molar inferior em uma jovem de 18 anos com cisto periapical. Assim, torna-se importante saber quais opções devemos tomar diante de uma situação clínica que não podemos resolver pelos métodos convencionais, e quais técnicas e abordagens temos para alcançar o sucesso do tratamento

2. Factors associated with postoperative signs and symptoms in teeth with periapical lesion: a longitudinal study
Resumo Este estudo teve como objetivo avaliar a associação das variáveis idade, sexo, posição no arco, comprimento do dente, amplitude do canal radicular e tamanho da lesão periapical com a ocorrência de sinais e sintomas pós-operatórios (dor, dor ao toque e edema) e o uso de analgésicos após o tratamento endodôntico com alargamento foraminal em

3. Negative Pressure Irrigation Presents Mineralizing Potential in Dogs’ Immature Teeth with Periapical Lesion
Resumo O objetivo do presente estudo in vivo foi avaliar o efeito da irrigação do canal radicular por pressão apical negativa e por pressão positiva na expressão de moléculas que são indicativas de diferenciação celular com fenótipo mineralizador em dentes de cães com rizogênese incompleta e lesão periapical. Um total de 30 dentes (60 raízes) f

4. Cytokines and chemokines associated with Treg/Th17 response in chronic inflammatory periapical disease
Abstract Cytokines and chemokines have a fundamental role in the maintenance of inflammation and bone response, which culminate in the development of chronic periapical lesions. Regulatory (Treg) and Th17 cytokines play a key role in regulating the immune response involved in this process. The aim of this study was to investigate the role of Treg and Th17 ce

5. Dendritic cells and their relation to apical peridontitis
Abstract: The purpose of this manuscript was to re-discuss apical periodontitis, apical biofilm, and its possible relationship with dendritic cells (DC). DCs are potent regulators of the immune system and their function is divided into three categories that involve the presentation of antigens: the presentation of antigens and activation of T cells; a not we

6. Treg and Th17 cells in inflammatory periapical disease: a systematic review
Abstract: The process involved in periapical lesions, which occur as an outcome of pulpal necrosis, is regulated by the immune system including regulatory T cells (Treg) and T helper 17 cell (Th17) responses. The objective of this study was to conduct a frequency systematic review to determine the presence of Treg/Th17 responses and the influence of these ce

7. Analysis of CD57+ natural killer cells and CD8+ T lymphocytes in periapical granulomas and radicular cysts
Abstract: The aim of this study was to compare the number of CD57+ natural killer (NK) cells and CD8+ T lymphocytes between periapical granulomas (PGs) and radicular cysts (RCs). Twenty-fives cases of PGs and 25 of RCs were submitted to histological analysis and immunohistochemistry using anti-CD57 and anti-CD8 biomarkers. Positive cells were counted in 10 f

8. Actinomycosis is not Frequent in the Periapex But is a Persistent Lesion
Resumo A actinomicose periapical causada por um patógeno anaeróbio Gram positivo caracteriza uma infecção extra-radicular típica. Esse estudo determinou a frequência e correlacionou o conteúdo das colônias bacterianas com o tamanho das actinomicoses periapicais. O estudo compreendeu um total de 218 lesões periapicais (LPs) (cistos, granulomas ou abs

9. Apical Negative Pressure irrigation presents tissue compatibility in immature teeth
Abstract Aim: To compare the apical negative pressure irrigation (ANP) with conventional irrigation in the teeth of immature dogs with apical periodontitis. Methods: Fifty-two immature pre-molar root canals were randomly assigned into 4 groups: ANP (n=15); conventional irrigation (n=17); healthy teeth (control) (n = 10); and teeth with untreated apical per

10. Chondroblastic osteosarcoma mimicking periapical abscess
Abstract Lesions of non-endodontic origin may mimic periapical abscess. Osteosarcoma is a rare malignant lesion. Case report The present report describes a case of chondroblastic osteosarcoma in the periapical region of teeth #29, #30, and #31 of an 18-year-old male. Clinical history showed self-reported discomfort in the right posterior gingiva for over a

11. Immunohistochemical expression of TGF-β1 and MMP-9 in periapical lesions
Abstract The objective of this study was to evaluate the expression of matrix metalloproteinase 9 (MMP-9) and transforming growth factor beta (TGF-β1) in periapical lesion samples correlated with the intensity of the inflammatory infiltrate and thickness of the epithelial lining. Forty-five cases of periapical lesions (23 periapical granulomas and 22 radicu

12. Relationship between hypertension and periapical lesion: an in vitro and in vivo study
Abstract The aim of this study was to compare potential aspects of periapical lesion formation in hypertensive and normotensive conditions using hypertensive (BPH/2J) and wild-type control (BPN/3J) mice. The mandibular first molars of both strains had their dental pulp exposed. At day 21 the mice were euthanized and right mandibular molars were used to evalu
