1. The mechanism: how dental resorptions occur in ameloblastoma
RESUMO As reabsorções radiculares “em plano” ou “em corte” são características do ameloblastoma e foram consideradas patognomônicas dessa lesão, diferenciando-o do cisto ósseo simples, queratocisto odontogênico e do cisto nasopalatino - nos quais elas estão ausentes, nos dentes envolvidos. Apesar dessa frequência elevadíssima e importante

2. Cytotoxicity and biocompatibility of a new bioceramic endodontic sealer containing calcium hydroxide
Abstract: This study evaluated the cytotoxicity and biocompatibility of a new bioceramic endodontic sealer (i.e., Sealer Plus BC) in comparison with those of MTA Fillapex and AH Plus. L929 fibroblasts were cultured and Alamar Blue was used to evaluate cell viability of diluted extracts (1:50, 1:100, and 1:200) from each sealer at 24 h. Polyethylene tubes tha

3. Tissue reaction to Aroeira (Myracrodruon urundeuva) extracts associated with microorganisms: an in vivo study
Abstract: Based on aroeira's (Myracrodruon urundeuva) antimicrobial activity and a future trend to compose intracanal medication, the aim of this study was to assess in vivo inflamatory tissue response to the extracts by edemogenic and histological analysis containing inactivated facultative and anaerobic microorganisms. For edema quantification, eighteen an

4. Biocompatibility and biomineralization assessment of bioceramic-, epoxy-, and calcium hydroxide-based sealers
Abstract Obturation of the root canal system aims to fill empty spaces, promoting hermetic sealing and preventing bacterial activity in periapical tissues. This should provide optimal conditions for repair, stimulating the process of biomineralization. An endodontic sealer should be biocompatible once it is in direct contact with periapical tissues. The aim

5. Dirofilariasis involving the oral cavity: report of the first case from South America
Oral dirofilariasis is very rare with non-specific clinical manifestations. Here, we report the case of a 65-year-old South American woman with a submucosal nodule on her right buccal mucosa. The nodule was slightly tender and painful. Differential diagnoses included mesenchymal (lipoma or fibrolipoma, solitary fibrous tumor, and neurofibroma) or glandular b

6. Morphometric evaluation of keratocystic odontogenic tumor before and after marsupialization
The aim of the present study was the morphometric evaluation of the epithelial lining and fibrous capsule in histological specimens of keratocystic odontogenic tumors (KOTs) before and after marsupialization. Histological sections from six KOTs that had undergone marsupialization followed by enucleation were photographed. The thickness and features of the ca

7. Mecanismos envolvidos na resposta imune e inflamatória frente à implantação de membrana de cortical óssea bovina no tecido subcutâneo de camundongos: caracterização histomorfométrica, imunoenzimática e molecular / Mechanisms involved in immune and inflammatory response to implantation of bovine bone cortical membrane in subcutaneous tissue of mice: characterization histomorphometric, imunoenzimatic and molecular
Advances related to the biomaterials science and tissue engineering seek to clarify the mechanisms involved in the biological response associated with the use of those devices and their interaction with the immune system. This study evaluated the inflammatory and immune response developed in mice after implantation bovine bone cortical membrane in subcutaneo

8. Avaliação da resposta inflamatória e processo de reparo do tecido subcutâneo de ratos, em contato com diferentes cimentos endodônticos
A presente pesquisa teve como objetivo verificar a resposta inflamatória e o processo de reparo em tecido subcutâneo de ratos a quatro cimentos endodônticos de composições distintas: Sealer 26, Epiphany, AH Plus e Endofill. Neste estudo foram utilizados 35 ratos Wistar, sendo que em cada animal foram confeccionadas 4 lojas cirúrgicas subcutâneas na re

9. Biocompatibility of RealSeal, its primer and AH Plus implanted in subcutaneous connective tissue of rats
OBJECTIVE: This study tested rat connective tissue response to RealSeal, RealSeal primer or AH Plus after 7, 15, 30, 60 and 90 days of implantation. MATERIAL AND METHODS: Thirty Wistar rats had subcutaneous sockets created on their back and received four implants each of polyethylene tubes containing one of the materials tested according to the groups: AH (A

10. Evaluation of the in vivo biocompatibility of hydroxyapatite granules incorporated with zinc ions
The incorporation of zinc onto biomaterials may improve their biological properties, since it is an essential trace element, involved on important steps of bone remodeling. The aim of this work was to evaluate the in vivo biocompatibility of previously characterized hydroxyapatite granules incorporated with 5% zinc (ZnHA), through a subcutaneous grafting tes

11. Mini-rhexis for white intumescent cataracts
PURPOSE: To compare the intraoperative safety of two techniques of capsulorhexis for intumescent white cataracts: traditional one-stage continuous curvilinear capsulorhexis and two-stage continuous curvilinear capsulorhexis. METHODS: This prospective comparative randomized study included two groups: the 1-CCC group (11 patients) received traditional one-stag

12. Film based on chitosan compared to autologous fat in the prevention of postoperative adhesions dorsal laminectomy in rabbits / Filme à base de quitosana comparado à gordura autógena na prevenção de aderências pós-laminectomia dorsal em coelhos
The adhesions formation after surgical procedures in the spine is a subject well studied in neurosurgery, according to the discomfort and postoperative pain suffered by patients. Several studies have been performed using anti-inflammatories, autologous grafts, xenografts and xenologer biomaterials and even in film form and gel with the aim of reducing or pre
