A quantitative and qualitative analysis of ultrasonic versus sonic endodontic systems on canal cleanliness and obturation.

Objective: The purpose of this study was to compare 2 irrigation techniques by evaluating canal cleanliness and obturation of lateral/accessory canals.

Study Design: Seventy-five extracted canines were instrumented to a size #40/0.06 taper.

Comparison of bacterial reduction in straight and curved canals using erbium, chromium:yttrium-scandium-gallium-garnet laser treatment versus a traditional irrigation technique with sodium hypochlorite.

Introduction: This study compared the reduction of Enterococcus faecalis in straight and curved canals using an erbium, chromium:yttrium-scandium-gallium-garnet laser and irrigation with 6.15% sodium hypochlorite (NaOCl).

Methods: Fifty-five single-rooted extracted teeth were divided into straight and curved canal groups.

Evaluation of Root-End Resections Performed by Er, Cr: YSGG Laser with and without Placement of a Root-End Filling Material.

Microleakage following root-end resections has a direct influence on the outcome of surgical endodontic procedures. This study compared the microleakage after root-end resections performed by the Er, Cr: YSGG laser or carbide burs with or without the placement of MTA, and evaluated the presence of microcracks and gaps at the interface of GP/MTA and the canal walls. Ninety single-rooted teeth were instrumented, obturated with GP and AH-Plus sealer, and divided into 3 experimental groups: (I) root-end resections were performed with the laser and G6 tips (parameters: 4.

Impact of Er,Cr:YSGG laser therapy on the cleanliness of the root canal walls of primary teeth.

Root canal therapy might be required for primary teeth displaying signs of pulpal inflammation or necrosis. Cleaning and shaping followed by obturation of the canal space with a resorbable paste have been widely performed with remarkable clinical success. However, lengthy endodontic procedures might be contraindicated when treating certain pediatric patients.

Obturation of root canal system treated by Cr, Er: YSGG laser irradiation.

The purpose of this study was to evaluate the number of canals and isthmuses obturated after Cr, Er: YSGG laser treatment. Fifty-two canals were instrumented to a size 40 Profile 0.06 file combined with RC-Prep and sodium hypochlorite, or sterile water.
