Impact of pecking amplitude on cyclic fatigue of new nickel-titanium files.

Objectives: The aim of this study is to determine the cyclic fatigue resistance of Mtwo Minimal in static and dynamic tests, with different amplitudes of pecking movements, at intracanal temperature.

Materials And Methods: Two hundred new 25-mm Mtwo Minimal rotary files (#10/0.035, #17.

Efficacy of 5% Aminolaevulinic Acid and Red Light on in Infected Root Canals.

Background: In this ex vivo study, the aim was to evaluate the effects of ALAD and red light on in infected root canals using a special intracanal fiber.

Methods: A total of 70 extracted, single-rooted teeth were used. The teeth were decoronated at the length of the roots to approximately 15 mm and then instrumented.

5-Aminolevulinic Acid and Red Led in Endodontics: A Narrative Review and Case Report.

The present study aims to discuss the main factors involving the use of 5-aminolevulinic acid together with red LED light and its application in endodontic treatment through a narrative review and a case report. Persistence of microorganisms remaining on chemical-mechanical preparation or intracanal dressing is reported as the leading cause of failure in endodontics. Photodynamic therapy has become a promising antimicrobial strategy as an aid to endodontic treatment.

Comparison between Single and Multi-LED Emitters for Photodynamic Therapy: An In Vitro Study on and Human Gingival Fibroblasts.

Aim Of The Study: The aim was to evaluate the effects of two LED devices, TL-01 and TL-03 in photodynamic therapy (PDT), on and on human gingival fibroblasts (HGFs). TL-01, characterized by a single emitter, irradiates one periodontal site at a time, whereas the multi-led device (TL-03) irradiates all vestibular sites of a single arch at a time.

Methods: bacterial suspensions and HGFs were incubated for 45 min with Aladent gel (ALAD) containing 5-aminolevulinic acid and then exposed to LED devices (ALAD-PDT), having different distance and timing of irradiation (TL-01 N (0.

The fate of overfilling in root canal treatments with long-term follow-up: a case series.

This study describes 6 cases of endodontic overfilling with successful clinical outcomes during long-term (up to 35 years) radiographic follow-up. Successful endodontic treatment depends on proper shaping, disinfection, and obturation of root canals. Filling materials should completely fill the root canal space without exceeding the anatomical apex.
