Resposta imune periapical à medicação intracanal à base de hidróxido de cálcio e selênio

O tratamento endodôntico tem como objetivo eliminar a contaminação microbiana dos sistemas de canais radiculares (SCR) por meio da instrumentação mecânica e irrigação química (PMQ). Quando não for possível a resolução em uma única sessão, o SCR deverá ser preenchido com uma medicação in...

Estudo de novos dispositivos, instrumentos e materiais empregados no tratamento endodôntico

Introdução: O tratamento endodôntico visa manter ou restabelecer a saúde do periodonto através do preparo biomecânico, utilizando instrumentos de níqueltitânio automatizados e associados com insertos ultrassônicos para potencializar a ação dos irrigantes. Os materiais empregados na endodontia ...

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 wi...

Validation of self-reported history of root canal treatment in a southern Brazilian subpopulation

Abstract The aim of this study was to assess self-reported history of root canal treatment (SRHRCT) as a method for detecting the presence of root canal treatment (RCT) and apical periodontitis (AP) in a southern Brazilian subpopulation. In this cross-sectional study, 136 military police officers from th...

Iodoform Vs Calcium Hydroxide/Zinc Oxide based pastes: 12-month findings of a Randomized Controlled Trial

Abstract This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused b...

Influencia de la medicación intracanal con pasta de hidróxido de calcio en la penetración del cemento obturador

Odontología (Ecuad.); 21 (2), 2019
La eliminación del hidróxido de calcio en el conducto radicular es determinante para el éxito del tratamiento endodóntico, los remanentes pueden interaccionar negativamente con los selladores endodónticos aumen-tando las filtraciones y disminuyendo la calidad de la obturación. Objetivo: Evaluar el ...

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

J. appl. oral sci; 27 (), 2019
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...

Comparison of apical periodontitis repair in endodontic treatment with calcium hydroxide-dressing and aPDT

Abstract This study evaluated the effect of antimicrobial photodynamic therapy (aPDT) on the endodontic treatment of apical periodontitis (AP). AP was induced in 48 premolars of 6 dogs. After biomechanical preparation, the teeth were divided into 4 groups: Calcium-Hydroxide (CH)/120d and CH/180d: root ca...

Root canal segmentation in cone-beam computed tomography: comparison with a micro-CT gold standard

Braz. j. oral sci; 18 (), 2019
Aim: The purpose of this study was to compare root canal volumes (RCVs) obtained by means of cone beam computed tomography (CBCT) to those obtained by micro-computed tomography (micro-CT) after applying different segmentation algorithms. Methods: Eighteen extracted human teeth with sound root canals were...

Comparison of rRNA-based reverse transcription PCR and rDNA-based PCR for the detection of streptococci in root canal infections

J. appl. oral sci; 27 (), 2019
Abstract Objective The rDNA-based method is unable to distinguish between alive and dead cells. Alternatively, bacterial viability can be assessed by molecular methods based on ribosomal RNA (rRNA). Therefore, this study aimed to detect viable streptococci in root canal samples using rRNA-based reverse...
