“…During retreatment, the mean difference between the AWL and post-treatment EWL remained less than AE0.5 mm, irrespective of the obturating material or the electronic root canal length measurement devices used. The results are comparable with those of Alves et al (23) and Goldberg et al (26).…”

“…Therefore in the present study, the AWL was recorded by subtracting 0.5 mm from the measurement obtained when file appeared at the foramen. The methodology used during EWL determination was modified from Alves et al (23) and Kaufman et al (28). The inner cylinder was filled with freshly mixed alginate.…”

“…Very limited studies have been performed to check the accuracy of different electronic root canal length measurement devices during retreatment with various obturating materials (23). The purpose of this in vitro evaluation was to study the accuracy of Root ZX and ProPex system during retreatment of canals obturated with different obturating materials (gutta-percha + zinc oxide-eugenol sealer; gutta-percha + AH plus sealer, and Resilon + Epiphany sealer).…”

ÖZETÇalışma boyunun doğru belirlenmesi, başarılı endodontik tedavinin en önemli basamaklarından biridir. Çalışma boyu, koronalde belirlenen bir referans noktasından apikalde kanal tedavisi işlemlerinin sonlandırılacağı sınıra kadar devam eden mesafe olarak tanımlanır. Genel olarak, minör apikal foramen, bu tedavi işlemlerinin bitirileceği son nokta olarak kabul gör-mektedir. Kök kanal uzunluğunun belirlenmesinde; parmak hassasiyeti, radyografik incelemeler, dijital görüntüleme yöntemleri, kağıt koni yöntemi, elektronik yöntem ve bu yön-temlerin farklı kombinasyonları kullanılabilmektedir. Bu derlemenin amacı, çalışma boyu belirleme yöntemlerinin çalışma prensipleri, avantajları, dezavantajları ve teknik gelişimlerinin gözden geçirilmesidir.Anahtar kelimeler: Endodonti, diş apeksi, odontometri, radyografi, taktil hissi SUMMARY Accurate determination of the working length is one of the crucial steps for a successful endodontic treatment. Working length is defined as the distance from a determined coronal reference point to the level at which root canal treatment procedures should terminate. Minor apical foramen is generally accepted as the termination point of these treatment procedures. Tactile sense, radiographic examinations, digital imaging systems, paper point technique, electronic method and different combinations of these methods are used for the determination of root canal length. The aim of this review is to present an overview on working principles, advantages, disadvantages and technical developments of the working length determination methods.Keywords: Endodontics, tooth apex, odontometry, radiography, tactile sense GİRİŞ Etkili bir kemomekanik preparasyon ve sızdırmaz bir kök kanal dolgusunun yapılabilmesi için çalışma boyunun doğru belirlenmesi şarttır. Kök kanal çalışma boyu, koronal olarak belirlenen bir referans noktasından kanalın şekillendirilip doldurulacağı noktaya kadar uzanan mesafedir.1 Kök kanal preparasyonu ve dolgusunun genel olarak 'minör apikal foramen' de bitirilmesi kabul görmektedir.2 'Minör apikal foramen' , kök pulpasının ve periodontal alanla birleştiği sınır olarak tarif edilir. 'Apikal daralım' veya 'fizyolojik foramen' olarak da adlandırılır. Anatomik apeksten 0-2mm içeride yer alabileceği gösterilmiştir.3 Bununla birlikte, apikal foramen her zaman dişin anatomik apeksi ile aynı doğrultuda yer almaz. Foramen açılımı apeksin lateralinde ve 3mm'yi bulan uzaklıklarda olabilmektedir.4 Dolayısıyla, hekimin gözle göremediği fakat tedavi başarısında büyük önem taşıyan bu noktanın belirlenmesi titizlikle yapılmalıdır.5 DERLEME

“…[1][2][3][4] Root canal length indicates the apical limit for the chemomechanical preparation and filling level; an improper setting can lead to instrumentation and filling beyond the apical foramen or short, which can hinder periapical healing. 3,5,6 Conventionally, to obtain the working length, radiographic techniques are used; however, they have some limitations, including superimposed images of anatomical structures, twodimensional images of threedimensional objects, distortion of images, difficulty determining the position of the apical foramen and the quality of the film or sensor which can negatively affect image quality. Additionally, some clinical circumstances limit their use, such as patients with macroglossia and nausea, in addition to pediatric and pregnant patients.…”

Introduction: Determining the working length in root canal treatment is very important, since it allows clinical procedures to be performed within the anatomical limits of the canal. Objective: The aim of this article is to report five cases in which root canal treatment was performed by an electronic method without trans-operative radiographic verification. Methods: Three maxillary and two mandibular molars diagnosed with irreversible pulpitis or pulpal necrosis were treated at the Endodontic Clinic of the Military Regional Hospital of Guadalajara, Mexico. After obtaining patient's informed consent, the working length of the root canal was measured with Raypex 6 apex locator, without radiographic verification. All root canals were prepared with Reciproc system instrumentation and filled by means of Tagger hybrid technique. Results: Postoperative radiographic control revealed that the level of root canal filling in 12 out of 14 root canals was from 0 to 2 mm of the radiographic apical apex. Conclusion: Results suggest that electronic conductometry is a reliable method to determine the working length. Additionally, it reduces the number of radiographs taken during root canal treatment.
