An cyclic fatigue resistance comparison of conventional and new generation nickel-titanium rotary files.

Background: New designs and processing of Niquel-Titanium (NiTi) have been introduced to increase resistance to cyclic fatigue. The purpose of this study was to compare the cyclic fatigue resistance of 3 NiTi rotary instruments, ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland), Profile Vortex Blue (PVB; Dentsply Tulsa Dental, Tulsa, OK, USA) and ProTaper Universal (PTU; Dentsply Maillefer, Ballaigues, Switzerland).

Material And Methods: A cyclic fatigue test was conducted operating instruments from ProTaper Next X2, Profile Vortex Blue 25.

Impact of heavy smoking on the clinical, microbiological and immunological parameters of patients with dental implants: a prospective cross-sectional study.

Aim: The aim of the present study was to investigate how heavy smoking influences the clinical, microbiological, and host-response characteristics in peri-implant sulcus fluid of patients with healthy dental implants.

Methods: A total of 29 individuals with 74 dental implants were included in the present study; 20 implants were in heavy smokers and 54 were in non-smokers. The modified gingival index, modified plaque index, and probing pocket depth were evaluated.

Measurement of the percentage of root filling in oval-shaped canals obturated with Thermafil Obturators and Beefill 2in1: In vitro study.

Background: The aim of the study was to measure the percentage of root canal fillings in long oval canals obturated with thermoplasticized gutta-percha techniques, Beefill 2in1® and Thermafil Obturators®.

Material And Methods: Fifty four mandibular incisors were selected after bucco-lingual and mesio-distal radiographs showed at 5 mm from apex an internal long:short diameter ≥2. Teeth were instrumented with Protaper Universal and divided in two groups of 27.

Clinical, microbiological, and immunological aspects of healthy versus peri-implantitis tissue in full arch reconstruction patients: a prospective cross-sectional study.

Background: Due to the world-wide increase in treatments involving implant placement, the incidence of peri-implant disease is increasing. Late implant failure is the result of the inability to maintain osseointegration, whose most important cause is peri-implantitis. The aim of this study was to analyze the clinical, microbiological, and immunological aspects in the peri-implant sulcus fluid (PISF) of patients with healthy dental implants and patients with peri-implantitis.

Treatment of multiple traumatized anterior teeth associated with an alveolar bone fracture in a 20-year-old patient: A 3-year follow up.

Intrusive luxation is a type of recognizable luxation injury represented by a deeper axial displacement of the tooth toward the alveolar bone. Treatment strategies include waiting for the tooth to return to its position, immediate surgical repositioning, and repositioning through dental traction by orthodontic devices. The aim of this case report was to present the management of severe dental trauma and later restoration following IADT.

Radiographic technical quality of root canal treatment performed ex vivo by dental students at Valencia University Medical and Dental School, Spain.

Objectives: To evaluate radiographically the quality of root canal fillings and compare manual and rotary preparation performed on extracted teeth by undergraduate dental students.

Study Design: A total of 561 premolars and molars extracted teeth were prepared using nickel-titanium rotary files or manual instrumentation and filled with gutta-percha using a cold lateral condensation technique, by 4th grade undergraduate students. Periapical radiographs were used to assess the technical quality of the root canal filling, evaluating three variables: length, density and taper.

An in vitro comparison of cyclic fatigue resistance of ProTaper universal and GT series X files.

Objective: The aim of this study was to compare the cyclic fatigue resistance of two nickel-titanium (NiTi) endodontic instruments from ProTaper and GT series X files.

Study Design: Cyclic fatigue test was realized with instruments from ProTaper: F1 and F3 (Denstply Maillefer, Ballaigues, Switzerland) and GT-X: 20.06 and 30.

In vitro comparison of cyclic fatigue resistance of ProTaper, WaveOne, and Twisted Files.

Introduction: The aim of this study was to compare the cyclic fatigue resistance of 3 nickel-titanium (NiTi) endodontic instruments from ProTaper, WaveOne (WO), and Twisted Files (TF).

Methods: Cyclic fatigue testing was conducted by operating instruments from ProTaper F2, WO 25 .08, and TF 25 .

Survival of implants placed with the osteotome technique: an update.

A literature review is made to analyze the survival of implants placed with the osteotome technique. A PubMed search was made based on the key words "osteotome AND dental implants", corresponding to publications between 1998-2008. The inclusion criteria were: a) a minimum of 10 patients; b) a minimum follow-up of 6 months; c) implants placed using the osteotome technique with or without indirect sinus lift; and d) specification of the implant number and survival rate.

Study of serum CTX in 50 oral surgical patients treated with oral bisphosphonates.

Objectives: To determine whether there is a relationship between the total BP dose administered and the variations in serum CTX concentration.

Study Design: The study included 50 patients requiring dental implant surgery and treated with oral BPs, seen in an Oral Surgery and Implantology Unit between January 2007 and June 2009. The patients were divided into two groups: those in which the medication was not suspended before obtaining the laboratory test sample, and those patients referred from other dental clinics in which BPs was suspended before reporting to our Unit.

Interleukins IL-6, IL-8, IL-10, IL-12 and periimplant disease. An update.

Introduction: A study is made of the usefulness of cytokines (such as interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and interleukin-12 (IL-12)) as markers of periimplant disease (mucositis and periimplantitis). An increase in the levels of these cytokines in dental implant crevicular fluid may give rise to a lack of osteointegration, bone loss or implant failure.

Objective: To review the literature relating IL-6, IL-8, IL-10 and IL-12 levels to dental implant surgery and periimplantitis.

Traumatic dental injuries among schoolchildren in Valencia, Spain.

Aim: The aim of the present study was to identify some factors related to the occurrence of dental trauma in mixed and permanent dentition.

Design Of The Study: Over a period of two months 1325, 6 to 18 year olds from three primary schools in Valencia were examined. Data was collected through clinical examinations and interviews and their Dental trauma was classified according to IADT's criteria.

Probiotic treatment in the oral cavity: an update.

Probiotics have been found to be beneficial to host health. Their primary use in medicine has been for the management of intestinal tract problems. In recent years, probiotics have been used as a treatment to promote oral health.
