Outcome of Endodontic Treatment: The Most Cited Publications.

Introduction: Bibliographic analysis using quantitative measurements such as citation number and citation density is a common method used to evaluate the impact of previously published studies on current research. Several bibliographic endodontic studies ranking publications based on their number of citations have been published. However, to date, a focus on the most cited articles related to the outcome of endodontic treatment is lacking.

Effect of master apical file size and taper on irrigation and cleaning of the apical third of curved canals.

Objective: Canal preparation generates a substantial amount of debris and smear layer (SL). The size and taper of the Master Apical File (MAF) affects on penetration of irrigants and subsequently canal cleaning efficacy. The aim of this study was to evaluate the effect of MAF size and taper on penetration of irrigants to the apical third of curved mesiobuccal (MB) canals of mandibular first molars.

In Vitro Comparison of Gutta-Percha Removal with H-File and ProTaper with or without Chloroform.

Introduction: Removal of root filling materials is one of the key steps in success of root canal retreatment. The purpose of this study was to evaluate the efficacy of H-File and ProTaper with or without chloroform in the removal of gutta-percha during retreatment of mandibular premolars.

Materials And Methods: Sixty mandibular premolars with one canal, and curvatures less than 30 degrees were used in this experimental study.

Efficacy of Two Rotary NiTi Instruments in Removal of Resilon/Epiphany Obturants.

Introduction: The success of endodontic retreatment is related to the complete removal of the obturation material from the root canal system. The aim of this study was to evaluate the efficacy of Mtwo R and ProTaper retreatment files in removing the Resilon/Epiphany system with or without chloroform during retreatment.

Materials And Methods: Sixty distal roots of first mandibular molars were prepared and laterally condensed with Resilon/Epiphany, then divided into four groups (15 each for retreatment): 1) Mtwo R/solvent; 2) Mtwo R; 3) ProTaper D/solvent; and 4) ProTaper D.

An in vitro study of mesiobuccal root thickness of maxillary first molars.

Introduction: Understanding the internal anatomy of root canal system can significantly influence outcomes of root canal treatment. The aim of this in vitro study was to measure the thickness of mesiobuccal root at different levels in maxillary first molars.

Materials And Methods: In this cross-sectional study, forty extracted human maxillary first molars were radiographed; accordingly, the mesial and distal root thicknesses of mesiobuccal (MB) roots were measured at four parallel horizontal levels.

Additive effect of a diode laser on the antibacterial activity of 2.5% NaOCl, 2% CHX and MTAD against Enterococcus faecalis contaminating root canals: an in vitro study.

This in vitro study was performed to evaluate the effect of a diode laser and common disinfectants used in combination on mono-infected dental canals. One hundred and six single-rooted human premolars were prepared and contaminated with Enterococcus faecalis. After two weeks of incubation, samples were divided into two experimental groups (n = 48) and two control groups (n = 5).

Effect of ultrasonication with EDTA or MTAD on smear layer, debris and erosion scores.

The purpose of this study was to compare the effects of ultrasonication with ethylenediaminetetraacetic acid (EDTA) and a mixture of tetracycline isomer, an acid, and a detergent (MTAD) as final canal irrigants on the smear layer, debris and erosion scores. Fifty-eight extracted single-rooted human teeth were instrumented with ProTaper rotary files up to size F3. According to the final irrigation regimen, the samples were distributed into the following groups: EDTA, MTAD, EDTA ultrasonicated for 1 min, and MTAD ultrasonicated for 1 min.

Efficacy of two rotary systems in removing gutta-percha and sealer from the root canal walls.

Introduction: The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in removal of gutta-percha (GP) and sealer from the root canal walls with and without use of solvent.

Materials And Methods: Sixty single-canalled distal roots of mandibular molars were prepared and root filled with gutta-percha and AH26. Each canal was randomly allocated to receive one of the retreatment techniques, Mtwo R or ProTaper.

Comparative study of the sealing ability of the lateral condensation technique and the BeeFill system after canal preparation by the Mtwo NiTi rotary system.

The purpose of this in vitro study was to compare the sealing ability of the lateral condensation technique and the BeeFill system after canal preparation by the Mtwo rotary system. Forty extracted single-rooted teeth were prepared by using the Mtwo rotary system. The teeth were then divided into 2 experimental groups (n = 15 each) and 2 control groups (n = 5 each).

Canal-centring ability of three rotary file systems in simulated curved canals: a comparative study.

Objective: To compare the canal-centring ability of M two , ProFile and RaCe rotary files, in simulated curved canals.

Materials And Methods: About 30 simulated canals were prepared by M two , ProFile and RaCe rotary files. Pre and post-operative pictures were super-imposed and transportations recorded.

A study of the relation between erosion and microhardness of root canal dentin.

Objective: The aim of this study was to find a relation between erosion and microhardness of root canal dentin after irrigation with different canal irrigants.

Study Design: Seventy-two single-canal human premolar teeth were selected and enlarged by rotary Protaper files. The middle part of each root was transversely sectioned to a 4-mm slice.

Endodontic Treatment of a Maxillary First Premolar with Type IV Buccal Root Canal: A Case Report.

The maxillary first premolar may present large number of anatomic variations. The clinician should be aware of the configuration of the pulp system. Maxillary first premolars usually have two canals.

Comparison of extracted teeth and simulated resin blocks on apical canal transportation.

Introduction: We aimed to compare apical canal transportation of extracted teeth and two types of simulated resin blocks.

Materials And Methods: Mesiobuccal root of extracted maxillary molars, high hardness simulated resin blocks (Knoop hardness=40) and low hardness simulated resin blocks (Knoop hardness=22) were prepared with K-files using step-back technique (n=15 canals in each group). Double exposure radiographic technique was used for extracted teeth.
