13. On the Formation of Hydroxyapatite Nano Crystals Prepared Using Cationic Surfactant
Being a major constituent of hard tissues found in humans, synthetic hydroxyapatite (HA) as a substitute to natural bone and teeth is gaining importance. In particular, nano hydroxyapatite is expected to impart considerably superior properties. The current research focuses on identification of mechanism of the formation of HA nano-crystals during its prepara

14. Computed tomography evaluation of rotary systems on the root canal transportation and centering ability
Abstract : The endodontic preparation of curved and narrow root canals is challenging, with a tendency for the prepared canal to deviate away from its natural axis. The aim of this study was to evaluate, by cone-beam computed tomography, the transportation and centering ability of curved mesiobuccal canals in maxillary molars after biomechanical preparation

16. Viabilidade da substituição de raízes de dentes humanos por raízes construídas em compósito para estudos de mecânica da fratura / Viability of replacing the roots of human teeth by roots made of composite for the study of fracture mechanics
OBJETIVO: A restauração de dentes tratados endodonticamente é um desafio para a Odontologia. A fratura do remanescente radicular é comum neste tratamento. São três os métodos utilizados para estudar as fraturas: a análise por elementos finitos, os que utilizam dentes naturais e aqueles que utilizam dentes artificiais. O uso de dentes naturais apresen

17. Clinical strategies for esthetic excellence in anterior tooth restorations: understanding color and composite resin selection
Direct composite resin restorations have become a viable alternative for patients that require anterior restorative procedures to be integrated to the other teeth that compose the smile, especially for presenting satisfactory esthetic results and minimum wear of the dental structure. Technological evolution along with a better understanding of the behavior o

18. Histopathological analysis of corticosteroid-antibiotic preparation and propolis paste formulation as intracanal medication after pulpectomy: an in vivo study
Intracanal medication in pulpectomy therapy is used between appointments with the objective of reducing pain and inflammatory processes in pulp and periapical tissues. Propolis has been known as a natural antibiotic and has been subject of medical and dental research due to its therapeutic properties such as antibiotic, analgesic and anti-inflammatory effect

20. Influence of chlorhexidine application on longitudinal adhesive bond strength in deciduous teeth
The aim of this study was to evaluate the influence of applying 2% chlorhexidine for 30 seconds after phosphoric acid conditioning of dentin on the immediate and long-term bond strengths in deciduous teeth. The occlusal enamel was removed from 40 human sound deciduous molars, which were exfoliated by natural means, and the dentin was conditioned with 37% pho

21. Aging and food source effects on mandibular stylets teeth wear of phytophagous stink bug (Heteroptera: Pentatomidae)
Studies were conducted to test the effect of age and food sources on wear of the mandibular teeth of the phytophagous pentatomid, Euschistus heros (F.). The total length (µm) of the area bearing the mandibular teeth, the length of the 1st tooth, and the height of the 2nd tooth for teneral (< 1 day-old) adults were significantly greater than that of adults f
