Evaluation of Time to Fracture and Vertical Forces Applied by a Novel Gentlefile System for Root Canal Preparation in Simulated Root Canals.

Introduction: A great number of studies performed in the last 3 decades have shown the superior mechanical features of nickel-titanium files as compared with stainless steel files. A novel file system recently developed, Gentlefile, defies these findings and claims to have superior qualities despite the fact it is made from stainless steel.

Methods: Three file systems were used in this experiment: ProTaper Next (X1, X2, and X3), RevoS (SC2, SC3, and AS30), and Gentlefile (GF1, GF2, and GF3).

[Single file endodontic treatment: a new era?].

Root canal shaping is one of the key stages of endodontic treatment, when performed properly, it is a predictive factor for the outcome of the treatment. It is critical for an adequate disinfection, which is more effective at the completion of a proper shaping procedure. The introduction of NiTi instruments into endodontic greatly improved the root canal shaping and decreased the time required for a full mechanical preparation.

Applying extrusive orthodontic force without compromising the obturated canal space.

Background: Complicated tooth fractures can be the unfortunate result of orofacial trauma and can offer a therapeutic challenge for the dentist. A conservative solution for gaining supragingival sound tooth structure often includes orthodontic forced eruption. Usually, this procedure is carried out by applying extrusive force after placing a provisional acrylic Richmond crown on the tooth.

Rapidly progressive internal root resorption: a case report.

The etiology of internal root resorption is not fully understandable, trauma and chronic pulpitis are considered the main risk factors. Usually the process is asymptomatic and diagnosed upon routine radiographic examination. This case report presents a rapid progression of internal resorption related directly to traumatic injury.

Replantation of an immature permanent central incisor following pre-eruptive traumatic avulsion.

The use of the erbium yttrium aluminium garnet (2,940 nm) in a laser-assisted apicectomy procedure.

If conventional endodontic treatment is not possible or not successful, apical endodontic surgery may be indicated. New techniques, materials and technologies have been used to increase the already high success rate of root canal treatment. The purpose of this article is to describe the use of the Erbium:YAG (2,940 nm) laser in treatment of apicectomy as a central tool, with the advantages of enhanced patient comfort, better bactericidal and decontamination effects.
