Introduction. Tooth avulsion in the young permanent dentition is a frequent finding, and its prognosis depends on the treatment of the avulsed tooth before replantation, the extra-alveolar time, the storage medium, and the patient's general health. The present report describes management of an immature avulsed lower central incisor 90 minutes after the accident. Methods. A right lower central i...

INTRODUCTION The aim of this in vitro study was to evaluate the bond strength of Photo-Activated Disinfection (PAD) system to dentin with different root canal sealers by using a push-out test design. MATERIALS AND METHODS A total of 30 extracted mandibular premolar teeth with single and straight roots were used. The crowns were removed and the root canals were prepared by using ProTaper rotar...

Microorganisms do play in pulpal and periapical infection. Success of endodontic treatment aims at effective eradication bacteria from the root canal space. This, turn, prevents further microbial recolonization. Persistent colonies lead to failure treatment. With advent photodynamic therapy (PDT), a novel invasive approach is aimed complete disinfection with elimination bacteria. Therefore, thi...

Endodontic irrigation aims to clean and disinfect the root canal system. Passive ultrasonic irrigation (PUI) is based on the use of an ultrasound-activated instrument into the root canal filled with irrigant. The aim of this study was to evaluate, ex vivo, the effectiveness of PUI in eliminating Enterococcus faecalis from root canals. Seventy-five extracted human single-root teeth were used. Af...

Microorganisms may persist in the root canal system after therapy (RCT). The purpose of this study was to explore metronidazole (MTR)- and chlorhexidine (CHX)-loaded hydrogels as potential application intracanal medicaments for disinfection. Ultraviolet cross-linked (gGels) were synthesized by GelMA solution photoinitiator, which loaded with MTR (MTR@gGels) CHX (CHX@gGels). gGels, MTR@gGels CHX...

introduction: disinfection and subsequent obturation of the root canal space require adequate mechanical enlargement of the canals. the purpose of this in vitro study was to compare the shaping ability of mtwo, race and medin rotary instruments during the preparation of curved root canals. materials and methods: sixty mesiobuccal root canals of mandibular molars with severe curvatures between 2...
