The high morphological complexity of premolars, has led to propose different techniques for successful endodontic therapy. The purpose of this report is to describe the ProTaper manual technique in a second mandibular premolar showing a high anatomical complexity. A patient of 19 years old co- mes to the clinic of endodontic in the Regional Hospi- tal (Temuco), diagnosed with irreversible pulpitis on tooth 35. Radiographic examination found that the tooth has two roots. For clinical suspicion of the presence of a third canal a Cone Beam computed tomography was requested, which confirmed the existence of a distolingual canal. Because it is a complex case, the increased taper endodontic technique was performed, allowing us to complete the endodontic therapy in less time and with less difficulty.

Background/Purpose: The objectives of this study were to identify the bilateral distolingual (DL) canals / roots of the mandibular first molars and second mesiobuccal (MB2) canals of the maxillary first molars in the same Turkish individuals using cone-beam computed tomography (CBCT). Materials and Methods: A total of 150 CBCT images including all mandibular and maxillary first molars were retrospectively investigated in a Turkish subpopulation. The patient age, sex and presence of roots and root canals were assessed. The frequency, of bilateral DL canals, DL roots, and MB2 canals were reviewed. Data were analyzed using Fisher’sexact test and Chi-square test. Results: The prevalences of right DL canals, DL roots and MB2 canals were 31.3, 14.0 and 34.7%, respectively. The prevalences of left DL canals, DL roots and MB2 canals were 31.3, 4 and 27.3%, respectively. There was no statistically difference in the frequency of right and left DL canals, DL roots of mandibular first molars and MB2 canals of maxillary first molars according to gender. Conclusion: CBCT is a competent tool for the detection of additional distolingual canals/roots and second mesio buccal canals, and it is a valuable aid for dentists providing root canal treatment.

Canal Morphology

Thorough knowledge of root canal morphology is essential for the endodontic therapy. There are rare variations in canal number and configuration in maxillary molars, which could affect treatment outcome. This paper presents the endodontic management of a maxillary first molar with two palatal canals in one root (Vertucci type IV) and a single buccal canal. In this paper cone-beam computed tomography was made to asses this morphology. This paper is intended to reinforce clinician’s awareness of the rare morphology of root canals.

Inflammation of the pulp is most common and difficult to diagnose. For it radiographs is necessary. One attempt to do is to assess its histogram and density. Radiography equipment that has the ability to analyze is cone beam computedtomography (CBCT). The purpose of this study is to analyze radiograph of the pulp chamber histogram: peak value,grayscale and trends, as well as the density on the condition reversible and irreversible pulpitis condition. The populationof this descriptive study is secondary data of CBCT-3D radiographs during 2012-2013. Selected sample of 75 data isreversible pulpitis, irreversible pulpitis 80 data, as well as 20 normal condition data as control. Data were analyzed byone way ANOVAand are presented in tables and graphs. The results showed that the value of the histogram under normalconditions showeda different significance for both the peak value of the reversible or irreversible pulpitis (p= 0.01). It isdifferent with a grayscale value, showed no significant different between normal with reversible pulpitis (p =0.997) and significantly different between normal and pulpitis reversible against pulpitis irrebversible (p= 0.03-0.01). There is a growing trend change is on the right direction of reversible and irreversible pulpitis. It was concluded that the irreversiblepulpitis, density and histogram shows the direction of more luscent compared with normal and reversible pulpitisconditions.

Objective: The complex root canal anatomy is inherently colonised by microbial flora. Endodontic treatment success is always related to adequate disinfection of the root canal space, which ultimately affects the treatment outcome. A thorough understanding of the external and internal root canal anatomy by using adequately imaging modalities is essential before planning any treatment. The aim of this study was to investigate the number and morphology of the root canals of maxillary and mandibular premolars in Chennai population. Material and Methods: Full-size cone-beam computed tomographic images were randomly collected from 100 patients, resulting in a total of 200 first and 200 second maxillary premolars as well as 200 first and 200 second mandibular premolars. All the eight premolars were analysed in single patients, who underwent cone-beam computed tomography scanning during pre-operative assessment (before implant surgery, orthodontic treatment, diagnosis of dental-alveolar trauma or difficult root canal treatment). Total number of roots and root canals, frequency and correlations between men and women were recorded and statistically analysed by using chi-square tests. The root canal configurations were rated according to the Vertucci’s classification. Results: In the maxillary first premolar group (n = 200), 36.3% had 1 root, 56.7% had 2 roots and 7.0% had 3 roots, with most exhibiting a type IV canal configuration. In the maxillary second premolar group (n = 200), 60% had 1 root, 29.8% had 2 roots and 10.2% had 3 roots, with the majority of single-rooted second premolars exhibiting a type I canal configuration. In the mandibular first premolar group (n = 200), 80.5% had 1 root, 9.8% had 2 roots and 5% had 3 roots. In the mandibular second premolar group (n=200), 90.1% had 1 root, 6.4% had 2 roots and 3.5 % had 3 roots, with most exhibiting a type I canal configuration. No statistical correlation was found between number of roots, gender and tooth position. Conclusion: This cone-beam computed tomographic study confirmed previous anatomical and morphological investigations. Therefore, the possibility of additional root canals should be considered when treating premolars. Keywords: Cone-beam computed tomography; Mandibular; Maxillary; Premolar; Root canal; Morphology.

During the course of this experimental study tomograms of extracted teeth were analyzed before and after filling the root canals with an endodontic material and fragments of broken metal instruments for root canal treatment. During the first stage of the experiment, untreated extracted teeth were scanned using conebeam computed tomography and microfocus cone-beam computed tomography. A comparative assessment of capabilities of the two methods of cone-beam computed tomography based on examination of untreated root canals was carried out. The second part of the study is dedicated to visualization of root canals that contain foreign high-density materials.

This study aimed to compare the canal transportation and canal centering ability in the preparation of curved root canals after instrumentation with TruNatomy (TN) (TN; Dentsply Sirona, Maillefer, Ballaigues, Switzerland) and ProTaper Gold (PG) (PG; Dentsply, Tulsa Dental Specialties, Tulsa, OK, USA) files using cone‑beam computed tomography (CBCT). 30 Single rooted extracted human teeth with root curvature ranging from 20-30° according to Schneider’s method were selected. Teeth with any visible cracks or fractures, calcifications, previous root canal treatments were excluded. The teeth were randomly assigned into two groups i.e. Group 1-TN and Group 2-PG (n = 15 each). The teeth were instrumented according to manufacturer’s guidelines for both the groups. Canals were scanned using a CBCT scanner before and after preparation to evaluate the transportation and centering ratio at 3 mm, 5 mm, and 7 mm from the apex. The data analysis was done using SPSS software and the test used was independent sample t test for comparison between the 2 groups.Data obtained suggested that TN group presented lesser canal transportation at the middle third of the root. The PG group showed better centering abitily at apical third of the root canal when both the groups were compared. TN resulted in less transportation than PG at the middle third, and PG showed better centering ability at the apical third. Overall, both systems safely prepared root canals, causing minimal errors.
