Abstract

Introduction: X-ray computed micro-tomography scanning allows high-resolution 3-dimensional imaging of small objects. In this study, micro-CT scanning was used to compare the ability of manual and mechanical glide path to maintain the original root canal anatomy. Methods: Eight extracted upper first permanent molars were scanned at the TOMOLAB station at ELET- TRA Synchrotron Light Laboratory in Trieste, Italy, with a microfocus cone-beam geometry system. A total of 2,400 projections on 360 have been acquired at 100 kV and 80 mA, with a focal spot size of 8 mm. Buccal root canals of each specimen (n = 16) were randomly assigned to PathFile (P) or stainless-steel K-file (K) to perform glide path at the full working length. Speci- mens were then microscanned at the apical level (A) and at the point of the maximum curvature level (C) for post-treatment analyses. Curvatures of root canals were classified as moderate (#35 ) or severe ($40 ). The ratio of diameter ratios (RDRs) and the ratio of cross-sectional areas (RAs) were assessed. For each level of analysis (A and C), 2 balanced 2-way factorial analyses of variance (P < .05) were performed to eval- uate the significance of the instrument factor and of canal curvature factor as well as the interactions of the factors both with RDRs and RAs. Results: Speci- mens in the K group had a mean curvature of 35.4 ` 11.5 ; those in the P group had a curvature of 38 ` 9.9 . The instrument factor (P and K) was extremely significant (P < .001) for both the RDR and RA parame- ters, regardless of the point of analysis. Conclusions: Micro-CT scanning confirmed that NiTi rotary PathFile instruments preserve the original canal anatomy and cause less canal aberrations.

JOE march 2012 - Analysis of Factors Associated with Cracked Teeth

Analysis of Factors Associated with Cracked Teeth

Deog-Gyu Seo, DDS, MS, PhD,* Young-Ah Yi, DDS, MS, PhD,† Su-Jung Shin, DDS, MS, PhD,‡ and Jeong-Won Park, DDS, MS, PhD‡

Abstract

Introduction: The purpose of this study was to analyze the characteristics, distribution, and associated factors of longitudinal fractured teeth according to the well- defined criteria of the American Association of Endodon- tists (AAE). Methods: One hundred seven teeth with longitudinal fracture from 103 patients were diagnosed and analyzed. The patients’ signs, symptoms, age, and sex were noted as well as the tooth number, dental arch, filling materials, size/classification of restoration, crack direction, pulp vitality, whether the patient had undergone endodontic treatment, bite test results, percussion test results, wear facet, and periodontal pocket depth. Results: Eighty-seven teeth were diag- nosed with a cracked tooth (81.3%), 14 were diagnosed with vertical root fracture (VRF, 13.1%), 4 had a split tooth (3.7%), and 2 had a fractured cusp (1.9%); 82.2% showed a sensitive reaction on the bite test. Longitudinal tooth fractures were observed most frequently in patient in their 40s. The upper first molar (28.0%) was most frequently cracked, followed by the lower first molar (25.2%), the lower second molar (20.6%), and the upper second molar (16.8%). Most longitudinal tooth fractures (72.0%) occurred mainly in restored teeth, whereas only 28.0% were found in intact teeth. Compared with resin (4.7%) or porcelain (0.9%), the use of nonbonded inlay restoration materials such as gold (20.5%) or amalgam (18.7%) increased the occur- rence of longitudinal tooth fractures. Out of 107 of longitudinal fractured teeth, 33 (30.8%) were treated endodontically and 74 (69.2%) were not. VRF was asso- ciated with endodontic treatment. Conclusions: The bite test is most reliable for reproducing symptoms. The combined use of various examination methods is recommended for detecting cracks and minutely inspecting all directions of a tooth. (J Endod 2012;38:288–292)

Curso de Aperfeiçoamento em Endodontia da EEC / São Leopoldo Mandic Campinas-SP

Curso de Aperfeiçoamento em Endodontia

Equipe de Endodontia de Campinas

São Leopoldo Mandic Campinas-SP

OBJETIVOS DO CURSO

Este curso possibilitará ao clínico o conhecimento necessário para realizar tratamentos endodônticos com maior facilidade, desmistificando os procedimentos desde o acesso até a obturação e selamento do elemento dental. O aluno terá a possibilidade de assistir a demonstrações, passo a passo, e realizar atividades laboratóriais de treinamento prévio (acesso cirúrgico, instrumentação manual e rotatória, odontometria, obturação com termoplastificação, selamento), para posteriormente realizar atendimentos em pacientes. Na parte teórica, será realizada uma discussão profunda dos protocolos básicos utilizados, sempre baseados na literatura pertinente, bem como na atividade clínica dos professores, possibilitando ao aluno, no transcorrer do curso, a otimização com qualidade na sua atividade clínica.
