1. Impact of calcium aluminate cement with additives on dental pulp-derived cells
Abstract Calcium aluminate cement (CAC) has been highlighted as a promising alternative for endodontic use aiming at periapical tissue repair. However, its effects on dental pulp cells have been poorly explored. Objective: This study assessed the impact of calcium chloride (CaCl2) and bismuth oxide (Bi2O3) or zinc oxide (ZnO) additives on odontoblast cell re

2. 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

3. Periapical bone response to bacterial lipopolysaccharide is shifted upon cyclooxygenase blockage
Abstract Objectives: Infection, inflammation and bone resorption are closely related events in apical periodontitis development. Therefore, we sought to investigate the role of cyclooxygenase (COX) in osteoclastogenesis and bone metabolism signaling in periapical bone tissue after bacterial lipopolysaccharide (LPS) inoculation into root canals. Methodology

4. Experimental furcal perforation treated with mineral trioxide aggregate plus selenium: immune response
Abstract The aim of this study is to evaluate the expression of cytokines in response to mineral trioxide aggregate (MTA) plus selenium in germ-free mice with experimental furcal perforation. The first left maxillary molar was opened, and the furcal area was perforated and treated with post-MTA-Se (experimental group). The same surgical intervention was perf

5. Factors affecting the periapical healing process of endodontically treated teeth
Abstract Tissue repair is an essential process that reestablishes tissue integrity and regular function. Nevertheless, different therapeutic factors and clinical conditions may interfere in this process of periapical healing. This review aims to discuss the important therapeutic factors associated with the clinical protocol used during root canal treatment a

6. 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

7. Histopathological analysis of corticosteroid-antibiotic preparation and propolis paste formulation as intracanal medication after pulpectomy: an in vivo study
Intracanal medication in pulpectomy therapy is used between appointments with the objective of reducing pain and inflammatory processes in pulp and periapical tissues. Propolis has been known as a natural antibiotic and has been subject of medical and dental research due to its therapeutic properties such as antibiotic, analgesic and anti-inflammatory effect

8. Tissue reaction to Endométhasone sealer in root canal fillings short of or beyond the apical foramen
OBJECTIVE: This study evaluated the response of periapical tissues to the endodontic sealer Endométhasone in root canal fillings short of or beyond the apical foramen. MATERIAL AND METHODS: Twenty root canals of premolars and incisors of 2 mongrel dogs were used. After coronal access and pulp extirpation, the canals were instrumented up to a size 55 K-file

9. Response of the periapical tissue of dogs' teeth to the action of citric acid and EDTA
The purpose of this study was to analyze the inflammatory response of dog's periapical tissues to 17% trisodium EDTA salt (pH 8.0) and 1% citric acid (pH 2.0). Saline was used as a control. Six adult dogs were used as the biological model of the study. The experimental units comprised 56 roots of mandibular molars (first and second) and premolars (first, sec

10. Avaliação da capacidade de selamento de três materiais obturadores em canais radiculares de pré-molares de cães preparados para pino intra-radicular expostos ao meio bucal
O presente estudo teve como objetivo avaliar in vivo a capacidade de selamento de três materiais obturadores constituídos de cimentos endodônticos resinosos, sendo dois (AH Plus e EndoRez) associados a cones de guta-percha, e um (Real Seal) a cones de Resilon, em pré-molares de cães, expostos ao meio bucal, após o preparo para colocação de pino prot�

11. Materiais para cimentação de restaurações protéticas: resposta no tecido subcutâneo de camundongos isogênicos e na polpa de dentes de cães / Luting materials for prosthetic restorations: Response in the subcutaneous tissue of isogenic mice and dogs pulp tissue
The purpose of this study was to evaluate the biocompatibility of different luting agents (Ketac Cem Easy Mix 3M ESPE and RelyX Unicem 3M ESPE), microscopically, by means of implants in the subcutaneous connective tissue of isogenic mice; microscopically and radiographically, after application to deep cavities, close to the pulp, in dogs teeth. In the study

12. Detecção imuno-histoquímica de células de langerhans em granuloma dentário e cisto radicular
Dental Granuloma and Radicular Cysts represent chronic periapical lesions that frequently affect the jaw bones. The Langerhans Cells are dendritic antigen-presenting cells that initiate primary T-lymphocyte-dependent immune response T. These cells play a important role in normal and pathological epithelial tissues as those seen in periapical chronic lesions.
