1. Qual medicação utilizar nos casos de pulpotomia em dentes decíduos?
Para casos de pulpotomias de dentes decíduos o Agregado Trióxido Mineral (MTA) apresenta resultados clínicos e radiográficos significativamente mais satisfatórios, em relação aos demais materiais. A preservação da vitalidade pulpar e indução da formação de dentina reparadora podem ser alcançadas com o uso do hidróxido de cálcio ou do MTA

2. Quais as indicações clínicas para a utilização do cimento de hidróxido de cálcio na prática clínica odontológica?
O cimento é empregado na proteção indireta do complexo dentino-pulpar, como curativos temporários e fixação de próteses provisórias. A forma de solução é útil para todos os tipos de limpeza de cavidades para desinfetá-las antes da proteção pulpar e da restauração, já a suspensão, além de ser utilizada para limpeza de preparos cavitári

3. Polymicrobial Leakage and Retention of MTA and Portland Cement in a Model of Apexification
Abstract Objective: To evaluate the sealing capacity and retention of apical barriers made with mineral trioxide aggregate (MTA) and Portland cement (PC). Material and Methods: Fifty-six bovine incisors were sectioned 8 mm above and 12 mm below the cement-enamel junction. The root canal was enlarged with a diamond drill to create a standard 2.5 mm diameter

4. Effects of MTA and Brazilian propolis on the biological properties of dental pulp cells
Abstract: The aim of this study was to evaluate the effect of mineral trioxide aggregate (MTA) and Brazilian propolis on the cell viability, mineralization, anti-inflammatory ability, and migration of human dental pulp cells (hDPCs). The cell viability was evaluated with CCK-8 kit after 1, 5, 7, and 9 days. The deposition of calcified matrix and the expressi

6. Evaluation of dentinogenesis inducer biomaterials: an in vivo study
Abstract When exposure of the pulp to external environment occurs, reparative dentinogenesis can be induced by direct pulp capping to maintain pulp tissue vitality and function. These clinical situations require the use of materials that induce dentin repair and, subsequently, formation of a mineralized tissue. Objective: This work aims to assess the effect

7. 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

8. A comparison of the sealing abilities between Biodentine and MTA as root-end filling materials and their effects on bone healing in dogs after periradicular surgery
ABSTRACT Objectives: To compare the sealing ability and biocompatibility of Biodentine with mineral trioxide aggregate (MTA) when used as root-end filling materials. Methodology: The Cell Counting Kit-8 (CCK-8) assay was used to compare the cytotoxicity of MTA and Biodentine. Twenty-one extracted teeth with a single canal were immersed in an acidic silver

9. Analysis of Molecular Changes Induced By Mineral Trioxide Aggregate On sPLA2
Resumo O objetivo deste estudo foi analisar os efeitos do MTA na estrutura e atividade enzimática da sPLA2 a fim de fornecer subsídios para melhoria na formulação do produto. O MTA em pó foi incubado por 60 min na presença de sPLA2 e analisado por cromatografia, espectroscopia de massa por eletropulverização (ESI-MS) e espalhamento de raios-X de baix

10. Influence of photobiomodulation therapy on root development of rat molars with open apex and pulp necrosis
Abstract This study aimed to evaluate the role of photobiomodulation (PBM) in apexification and apexogenesis of necrotic rat molars with an open apex. Rat molars were exposed to the oral environment for 3 weeks. Canals were rinsed with 2.5% NaOCl and 17% EDTA, filled with antibiotic paste and sealed. After 7 days, canals were rinsed and divided into six grou

11. Hypertension affects the biocompatibility and biomineralization of MTA, High-plasticity MTA, and Biodentine®
Abstract This study evaluated the effect of hypertension on tissue response and biomineralization capacity of white Mineral Trioxide Aggregate (MTA), High-plasticity MTA (MTA HP), and Biodentine® (BDT) in rats. Polyethylene tubes filled with MTA, MTA HP, BDT, and the control group (empty tubes) were placed into the dorsal subcutaneous tissue of 32 male rats
