Dissimilar Sequelae Caused by Single Dental Trauma: A Case Report with Long-Term Follow-up.

Immediate care and accurate diagnosis are essential for treating dental trauma. This report presents a 7-year-old boy suffered a bicycle accident with direct trauma to the mouth and extrusive luxation of teeth #11 and #21. The emergency treatment was performed within the first hour.

Regenerative Endodontic Treatment of a Traumatized Immature Necrotic Permanent Incisor: A Case Report.

The current case report documents the clinical approach adopted for a traumatized immature necrotic permanent upper left central incisor after a bike accident. The treatment involved regenerative endodontic procedures (REPs) using "High Plasticity Mineral Trioxide Aggregate" (MTA Repair HP) as a cervical barrier over blood clot. The preservation included three years of follow-up appointments of clinical evaluations and periapical digital radiographs.

Effect of Different Root Canal Drying Protocols on the Bond Strength of Two Bioceramic Sealers.

Objectives:  This study evaluated the effect of two different drying protocols on the dentin bond strength of two different bioceramic sealers (Sealer Plus BC [SP] and Bio C Sealer [BCS]). Bond strength and failure mode were evaluated according to the sealer, drying protocol, and root canal third.

Materials And Methods:  Sixty extracted human mandibular single-rooted premolars were selected after anatomical standardization.

Percentage of Gutta-Percha-, Sealer-, and Void-Filled Areas in Oval-Shaped Root Canals Obturated with Different Filling Techniques: A Confocal Laser Scanning Microscopy Study.

Objective:  This study compared different obturation techniques, analyzing percentage of areas filled with gutta-percha, sealer, and voids (PGFA, PSFA, and PVFA, respectively) in oval-shaped root canals.

Materials And Methods:  A total of 60 extracted human mandibular central incisors were decoronated, instrumented, and irrigated using the same protocol. After drying, the root canal was filled with AH Plus labeled with 0.

Evaluation of fluoride and sodium hypochlorite solutions during the electrochemical dissolution of conventional NiTi instruments and Gold thermomechanically treated NiTi instruments.

Aim: To compare the dissolution time of two solutions, a fluoride solution and a sodium hypochlorite solution, both saturated with sodium chloride, during the electrochemical dissolution of instruments consisting of conventional nickel-titanium alloy and Gold thermomechanically treated nickel-titanium alloy.

Methodology: Two solutions, an NaF solution consisting of 12 g L NaF with 180 g L NaCl and an NaOCl solution consisting of 2.5% NaOCl with 180 g L NaCl, were evaluated in a polarization test of a sample of 48 ProTaper Universal F1 (PTU F1) and WaveOne Gold Small (WOGS) instruments.

Microscopic evaluation of the dentinal walls of extracted human teeth following electrochemical dissolution of fragmented nickel-titanium instruments.

Electrochemical dissolution is a method in which fluoridated solution in direct contact with the fractured instrument receives an electrical current that speeds up fragment dissolution. The aim of this study was to assess the integrity of dentinal walls during the electrochemical dissolution of fractured rotary endodontic instruments in extracted human teeth. Forty-five human mandibular incisors subjected to the electrochemical dissolution process using fluoride solution with low NaCl concentration (LC group: NaF 12 g/L + NaCl 1 g/L, pH = 5.

Management of Dental Intrusion and Lateral Luxation: Case Report with 10 Years Follow-up.

This case report documents the clinical approach adopted for two maxillary incisors with intrusion and lateral luxation trauma. The proposed procedures involved reposition of both teeth, one of them with surgical extrusion and endodontic procedure for both, with 10 years of follow-up.

Management of Multiple Dental Trauma: Case Report with Eight-Year Follow-up.

This case report documents the clinical approach adopted for two maxillary incisors with intrusion and horizontal root fracture in the middle third after trauma. The proposed procedures involved maintaining pulp vitality and periodontal stability of the fractured teeth with 8 years of follow-up.

Maintenance of Pulp after Horizontal Root Fractures in Three Maxillary Incisors: A Thirteen-Year Evaluation.

This case report documents the clinical approach adopted for three upper incisors with horizontal root fracture in the middle or cervical third. The proposed procedures involved maintaining pulp vitality and periodontal stability of the fractured teeth with 13 years of follow-up.

Electrochemical dissolution of fractured nickel-titanium instruments in human extracted teeth.

Aim: To assess the effect of sodium chloride concentration in fluoridated solutions during the electrochemical dissolution of fractured rotary endodontic instruments.

Methodology: Two solutions were assessed (solution 1: NaF 12 g L  + NaCl 1 g L , pH = 5.0; and solution 2: NaF 12 g L  + NaCl 180 g L , pH = 5.

Influence of calcium hydroxide dressing and two irrigants on the filling of artificial lateral canals.

Context: This study was carried out on the assumption that calcium hydroxide [Ca(OH) 2 ] dressing and irrigants may influence the obturation of lateral canals.

Aims: To evaluate the influence of 2.5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) gel and Ca(OH) 2 on the filling of artificial lateral canals.

Evaluation of cutting ability and plastic deformation of reciprocating files.

This in vitro study evaluated the cutting ability of reciprocating files and the deformations caused by their multiple use. Five Reciproc® R25 files were divided into five groups for 10 simulated root canal preparations each. The resin blocks were weighed and photographed (12.
