In Vitro Alteration by Dentine and Protein of the Antimicrobial Activity of Two Endodontic Irrigants: HybenX and Sodium Hypochlorite.

Irrigant solutions commonly used for the treatment of endodontic infections can be inhibited by both organic and inorganic substances. The aim of this study was to evaluate the in vitro antimicrobial activity of the novel irrigant HybenX and 2.5% and 5% sodium hypochlorite against , in presence of dentine powder (DP) or bovine serum albumin 20% (BSA) as inhibitory agents.

Influences of 432 Hz Music on the Perception of Anxiety during Endodontic Treatment: A Randomized Controlled Clinical Trial.

Introduction: Patients undergoing endodontic therapy often have severe perioperative and intraoperative anxiety, which may lead to increased perceptions of pain and vital sign instability throughout treatment. The purpose of this study was to test the influences of music, as a nonpharmacologic adjuvant, in terms of significant changes for systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) before, during, and after endodontic treatment in a population with different levels of anxiety assessed with the Corah Dental Anxiety Scale.

Methods: A total of 100 patients were recruited in the present study; before starting the endodontic treatment, the interviewer administered the Corah Dental Anxiety Scale to the participants to assess the baseline level of anxiety.

Shaping ability of waveone primary reciprocating files and ProTaper system used in continuous and reciprocating motion.

Introduction: The purpose of this study was to compare the shaping effects of Wave One (Dentsply Maillefer, Ballaigues, Switzerland) and full-sequence ProTaper nickel-titanium (NiTi) files (Dentsply Maillefer) used in reciprocating and conventional movements in a simulated canal.

Methods: Seventy-five S-shaped canals in resin blocks were randomly allocated to 3 groups (n = 25): WaveOne (group 1), full sequence of ProTaper Universal files in conventional movements (group 2), and full sequence of ProTaper Universal files in reciprocating movements (group 3). Preoperative and postoperative photographs of the simulated canals were taken under standardized conditions, after which they were accurately superimposed.

Mineral trioxide aggregate as apical plug in teeth with necrotic pulp and immature apices: a 10-year case series.

Introduction: This 10-year study evaluated the clinical and radiologic outcomes of teeth with necrotic pulp, immature apices, and periapical lesions treated with the mineral trioxide aggregate (MTA) apical plug technique.

Methods: Seventeen single-rooted immature teeth with necrotic pulp and periapical lesion from 17 patients treated between January 2001 and December 2001 were included in this study. Apical obturation on all teeth included in the study was completed in 2 visits: first using calcium hydroxide as an interappointment intracanal medication and a second visit for the creation of the artificial apical barrier with MTA.
