3. Comparison of automatic and visual methods used for image segmentation in Endodontics: a microCT study
Abstract To calculate root canal volume and surface area in microCT images, an image segmentation by selecting threshold values is required, which can be determined by visual or automatic methods. Visual determination is influenced by the operator's visual acuity, while the automatic method is done entirely by computer algorithms. Objective: To compare betw

5. Determination of Boron Isotope Ratios in Tooth Enamel by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) After Matrix Separation by Ion Exchange Chromatography
Boron isotopes in teeth has been a new proxy for dietary reconstructions and its resistance to diagenetic alteration. In this study a method using inductively coupled plasma source mass spectrometry (ICP-MS) for the measurement of boron isotope ratio in human dental enamel has been developed. Human dental enamel were digested with HNO3-H2O2 in a microwave sy

6. In situ protocol for the determination of dose-response effect of low-fluoride dentifrices on enamel remineralization
No in situ protocol has assessed the dose-response effects of fluoride dentifrices involving low-fluoride formulations. Objective: To assess the ability of an in situ remineralization model in determining dose-response effects of dentifrices containing low fluoride concentrations ([F]) on bovine enamel. Material and Methods: Volunteers wore palatal ap

7. Avaliação em tomografia computadorizada por feixe cônico da quantidade de tecido ósseo de suporte, vestibular e lingual, dos incisivos centrais supeiores e a relação com suas inclinações / Cone Beam Computed Tomography evaluation of the amount of buccal and lingual supporting bone tissue of maxillary central incisors and relationship with tipping
The present study evaluated, by means of Cone Beam Computed Tomography (CBCT), the amount of supporting bone tissue, vestibular and lingual, in the upper central incisors (teeth 11 and 21) and the relationship with their dental inclinations (1.PP). The sample consisted of 30 images obtained by CBCT, belonging to adult patients, between 20 and 47 years old, o

8. Avaliação da eficácia da desinfecção de instrumentos usados durante o período transoperatório do tratamento endodôntico / Evaluation of the desinfection efficacy of instruments used during the transoperatory period in endodontic treatment
This investigation aimed to evaluate the antimicrobial efficacy of disinfectant agents used to maintain the disinfection of endodontic instruments during the transoperatory period in endodontic treatment. The antimicrobial activity of disinfectants isopropyl alcohol, acetone and peracetic acid were evaluated upon planktonic micro-organisms by time kill assay

9. In vivo accuracy of conventional and digital radiographic methods in confirming root canal working length determination by Root ZX
OBJECTIVES: To compare, in vivo, the accuracy of conventional and digital radiographic methods in determining root canal working length. MATERIAL AND METHODS: Twenty-five maxillary incisor or canine teeth from 22 patients were used in this study. Considering the preoperative radiographs as the baseline, a 25 K file was inserted into the root canal to the poi

11. Análise mecânica de retentores intra-radiculares / Mechanical analysis of endodontic post
The fiber-reinforcement composite (FRC) posts introduced the new concept of restorative system, in which the various components of the reconstruction: post, cement, filling material and dentin have now become a complex mechanically homogeneous. The knowledge of the structure, composition and physical properties of these fiber posts systems is important in or

12. Influence of cervical preflaring on determination of apical file size using to instrumentation in root of first maxillary molars: SEM analysis / Influência do alargamento cervical na determinação do instrumento apical inicial utilizado para instrumentação dos canais radiculares de primeiros molares superiores: análise por microscopia eletrônica de varredura
The aim of this study was to investigate ex vivo the influence of cervical preflaring on determination the initial apical file (IAI), in the working length (WL), of the root canals of the maxillary first molars and to determine the shape of the canal at 1 mm from the apex. Fifty teeth were randomly divided into 5 groups (n=10) in accordance with the preflari
