Outcome measures, collected by a blind examiner, included complete root coverage (CRC), recession reduction (RecRed), keratinized tissue (KT) gain, increase in gingival thickness (GT), patient satisfaction and root coverage esthetic score (RES).

Stability of root coverage outcomes at single maxillary gingival recession with loss of interdental attachment: 3-year extension results from a randomized, controlled, clinical trial.

Background: The aim of this study was to assess the stability of root coverage outcomes 3 years after Connective Tissue Graft (CTG) plus Coronally Advanced Flap (CAF) or CAF alone at single maxillary gingival recession with minimal inter-dental clinical attachment loss.

Material And Methods: Twenty-four of the original 29 patients, 13 treated with CAF + CTG and 11 with CAF, were available for the 3-year follow-up. Measurements were performed by a blind and calibrated examiner.

Soft-tissue re-growth following fibre retention osseous resective surgery or osseous resective surgery: a multilevel analysis.

Background: The aim of this study was to assess soft-tissue re-growth following Fibre Retention Osseous Resective Surgery (FibReORS) or Osseous Resective Surgery (ORS) over a 12-month healing period.

Material And Methods: Thirty patients with chronic periodontitis showing persistent periodontal pockets at posterior natural teeth after cause-related therapy were enroled. Periodontal pockets were associated with infrabony defect ≤3 mm; 15 patients were randomly assigned to FibReORS (test group) and 15 to ORS (control group).

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.

Endodontic management in oculo-facio-cardio-dental syndrome: a case report.

Introduction: Oculo-facio-cardio-dental (OFCD) syndrome is an X-linked dominant trait. OFCD syndrome is characterized by congenital cataract with secondary glaucoma ocular defects; ventricular and atrial septal defects or mitral valve prolapses; facial traits such as a long narrow face, a high nasal bridge, a bifid nasal tip; and dental anomalies that include radiculomegaly, oligodontia, root dilacerations, malocclusion and delayed eruption. This clinical report describes the endodontic treatment for a 16-year-old girl who suffers from OFCD syndrome.

Mineral trioxide aggregate as repair material for furcal perforation: case series.

The purpose of treating furcal perforation is to seal the artificial communication between the endodontic space and the periradicular tissue to prevent alveolar bone resorption and damage to the periodontal ligament. These complications are not infrequent in cases of furcal and/or old perforations, which show a worse prognosis than fresh, small, coronal, and apical perforations. Mineral trioxide aggregate (MTA) is widely used to seal perforations because of its biocompatibility and sealability.

The use of MTA in teeth with necrotic pulps and open apices.

Three clinical cases have been treated with the use of an apical plug of MTA for apexification. All three cases were central incisors that had suffered premature interruption of root development as a consequence of trauma. According to the treatment protocol, the root canals were rinsed with 5% NaOCl; then, calcium hydroxide paste was placed in the canals for 1 week.
