Comparación de la actividad antimicrobiana de cementos selladores en endodoncia
Comparison of the antimicrobial activity of sealing cements in endodontics

Rev. ADM; 81 (1), 2024
Introducción: la persistencia de microorganismos en los conductos radiculares es uno de los principales factores del fracaso endodóncico. Por ello la importancia de conocer las propiedades antimicrobianas de los distintos tipos de selladores. Objetivo: realizar una comparación con base en la evide...

Randomized Clinical Study of the Use of MTA and Biodentine™ for Pulpotomy in Primary Teeth

ABSTRACT Objective: To verify, through clinical and radiographic evaluations, the in vivo response of the dentin-pulpal complex of human primary teeth after pulpotomy with MTA and Biodentine™ in a follow-up period of 3, 6, and 12 months. Material and Methods: Thirty teeth were divided into MTA pu...

Effect of liners on composite resin microleakage after selective carious lesion removal: an experimental study

J. oral res. (Impresa); 11 (3), 2022
Objetive: To evaluate microleakage of composite resins (CR) placed over different cavitary liners after managing deep caries lesions through selective removal of soft carious tissue to soft dentin (SRCT-S). Material and Methods: Fifty four human teeth were collected for microleakage testing. Each assay c...

Effect of Color and Surface Roughness of Glass Ionomer Cements Submitted to Solutions Based on Ilex paraguariensis

ABSTRACT: The present study analyzed the color change (DE) and surface roughness (Ra) of glass ionomer cements (GICs) subjected to typical herbaceous South American beverage action - Ilex paraguariensis. 90 specimens (n = 10) were made: M1 - GIC Riva Light Cure® (SDI); M2 - GIC Riva Self Cure® (SDI); M...
