Introduction The main purpose of endodontic treatment is to clean the root canal system, eliminate the infected and toxic contents, and shape it in order to get a tridimensional obturation. The aim of this paper is to inform dental practitioners about crown-down techniques for root canal preparation using nickel-titanium rotary instruments. Root canal preparation Today most endodontists believe that root canal preparation is more officious, cleaning and shaping are better, if pre-enlargement of coronal two thirds is performed first, and shaping of the apical part later. Machine driven rotary instruments provide much quicker and better root canal preparation. Conclusion Contemporary endodontic rotary files vary in regard to their taper, cutting blades, guiding tip and material they are made of. The usage of rotary nickel-titanium files adds a new quality to root canal preparation.

Abstract Background The purpose of this study was to evaluate the shaping advantage of M-wire NiTi ProTaper NEXT (PTN) compared with a conventional NiTi ProTaper Universal (PTU) file in heavy curvature canal. The shaping ability was measured by the amount of canal cutting and transportation between the PTN and conventional PTU. Methods Root canal shaping by the PTN and conventional PTU was classified into two experimental groups according to the final tip size, ISO #25 or ISO #40. Eighty-four J-shaped root canals (10°, 20°, 30° apical curvature) in resin block were used. Results After adjusting for the level and canal wall side, the mean transportation did not significantly decrease between the PTN and PTU with ISO #25. Significantly less deviation occurred with the PTN and PTU between 10° and 30° using ISO #40. Conclusions The M-Wire NiTi PTN improves file flexibility and enables accurate canal shaping for heavy curvature canals.

ABSTRACT Aim C-shaped canal system is a seldom-found root canal anatomy which displays a challenge in all stages of endodontic treatment. According to the literature, this type of canal morphology is not a common finding in the mandibular first molar teeth. Background This case report presents endodontic management of a mandibular first molar with a C-shaped canal system. Case report Root canal system was cleaned and shaped by nickel-titanium (NiTi) rotary instruments combined with selfadjusting file (SAF). Obturation was performed using warm, vertical condensation combined with the injection of warm gutta-percha. Follow-up examination 12 months later showed that the tooth was asymptomatic. The radiological findings presented no signs of periapical pathology. Clinical significance The clinician must be aware of the occurence and complexity of C-shaped canals in mandibular first molar teeth to perform a successful root canal treatment. The supplementary use of SAF after application of rotary instruments in C-shaped root canals might be a promising approach in endodontic treatment of this type of canal morphology.

Root Fractures

Evidence indicates that root canal preparation is a critical step upon which the prognosis of the endodontic treatment depends. Vertical root fractures can furtherly develop as propagations from the previously formed dentin cracks. Therefore, root canal preparation should be carefully approached with the minimal crack formation and careful dentin removal. Different modalities have been proposed in the literature and rotary systems are most commonly used nowadays. Although the reported efficacy of these modalities is high, evidence shows that they are usually associated with a considerable risk of crack formation. In the present literature review, we have discussed the effects of rotary instrumentation and root canal preparation on dentinal crack formation based on evidence from the different studies in the literature. Our evidence showed that all of the investigated approaches to prepare root canals adequately can result in crack formation. The different rotary instrumentations also showed variable frequencies of developing dentinal cracks, and evidence from some comparative investigations shows that ProTaper modalities are associated with the least frequencies of the events. However, to make a solid conclusion for clinical practice, further research is still needed to validate our current evidence.

ABSTRAKPendahuluan: Penatalaksanaan kasus penyakit pulpa yang disertai dengan lesi periapikal dapat dilakukan dengan perawatan saluran akar tanpa intervensi bedah. Preparasi biomekanis pada perawatan endodontik non-bedah dapat mengeliminasi bakteri dari saluran akar dan mencegah terjadinya infeksi berulang setelah dilakukannya obturasi. Kompleksitas anatomi menyebabkan keterbatasan preparasi biomekanis saluran akar, sehingga perawatan dapat mengalami kegagalan. Variasi anatomi saluran akar pada gigi molar pertama rahang atas umumnya terdapat pada bagian palatal akar mesiobukal yang disebut sebagai saluran akar mesiobukal kedua dengan insidensi 94%. Saluran akar mesiobukal kedua berukuran lebih sempit dan dangkal dibandingkan saluran akar mesiobukal pertama, sehingga dibutuhkan beberapa metode untuk menentukan lokasi orifis tersebut. Tujuan laporan kasus ini adalah membahas mengenai penatalaksanaan non-bedah gigi pasca perawatan endodontik parsial yang disertai dengan lesi periapikal. Laporan kasus: Pasien perempuan berusia 28 tahun datang dengan keluhan gigi belakang kiri atas sakit berdenyut sejak 1 bulan, gigi tersebut pernah dirawat saluran akarnya beberapa tahun sebelumnya. Pemeriksaan klinis menunjukkan terdapat tambalan permanen pada gigi 26. Pemeriksaan radiografis menunjukkan adanya gambaran radiopak pada email mesio-oklusal hingga mencapai dasar kamar pulpa, pelebaran ligamen periodontal, terputusnya lamina dura, serta lesi periapikal pada akar mesial dan palatal. Preparasi akses dilakukan pada gigi 26, dilanjutkan dengan penentuan lokasi orifis mesiobukal kedua. Empat saluran akar dipreparasi menggunakan instrumen rotary nickel titanium dengan teknik crown down dan dilakukan obturasi teknik kondensasi lateral. Restorasi definitif berupa mahkota penuh porselen. Simpulan: Lesi periapikal sembuh setelah dilakukan preparasi pada saluran akar mesiobukal kedua sehingga pengetahuan mengenai anatomi dan variasi internal saluran akar gigi sangat penting dalam keberhasilan perawatan endodontik non-bedah.Kata kunci: Perawatan endodontik non-bedah; previously initiated therapy; lesi periapical; mesiobukal kedua  ABSTRACTIntroduction: The management of pulp disease cases accompanied by periapical lesions can be done by root canal treatment without surgical intervention. Biomechanical preparations for non-surgical endodontic treatment can eliminate bacteria from the root canal and prevent re-infection after obturation. However, the complexity of the anatomy limits the biomechanical preparation of the root canal so that treatment can fail. Anatomical variations of the root canal in the maxillary first molars are generally found in the palatal part of the mesiobuccal root, which is the second mesiobuccal root canal with an incidence of 94%. The second mesiobuccal root canal is narrower and shallower than the first mesiobuccal root canal, so several methods are needed to determine the location of the orifice. The purpose of this case report was to discuss the non-surgical management of teeth after partial endodontic treatment accompanied by periapical lesions. Case report: A 28-year-old female patient complained of throbbing pain in the left upper back tooth for one month. The tooth had had its root canal treated several years before. Clinical examination revealed permanent fillings on tooth 26. Radiographic examination showed the radiopaque appearance of mesio-occlusal enamel to the floor of the pulp chamber, widening of the periodontal ligament, rupture of the lamina dura, and periapical lesions of the mesial and palatal roots. Access preparation was performed on tooth 26, followed by the determination of the location of the second mesiobuccal orifice. Four root canals were prepared using a rotary nickel titanium instrument with a crown down technique and obturation with lateral condensation technique. The definitive restoration is a full porcelain crown. Conclusions: Periapical lesions healed after preparation of the second mesiobuccal root canal. This result proves that knowledge of the anatomy and internal variations of the root canal is fundamental in the success of non-surgical endodontic treatment.Keywords: Non-surgical endodontic treatment; previously initiated therapy; periapical lesions; second mesiobuccal canal

The apical limit of root canal instrumentation has always been a matter of great controversy. Despite the large number of published studies on this subject, a consensus has not yet been reached. In fact, the recent discussion on apical patency and cleaning of the apical foramen, as well as the incorporation of these procedures to the endodontic treatment, seem to have raised even more polemics. It is likely that all this polemics has its roots in the lack of interrelation between the theoretical knowledge of pulp stump and periapical tissues and the real clinical practice. By addressing the most important aspects of this theme, this paper aims to present news concepts about the importance of apical patency and cleaning of the apical foramen during root canal preparation.
