Effect of a diamond-like carbon film on the mechanical and surface properties o...

Introduction: Microwave-cured polymethylmethacrylate (MCPM) are commonly used in dentistry due low cost, transparency and easy handling. However, do not have a long useful life, due to their chemical fragility and low hardness and wear resistance. Aim: Assessing the effect of a diamond-like carbon (DLC) film coating on the mechanical and surface properties of MCPM. Methodology: The MCPM samples were divided int...

Adaptation of the single-cone in prepared long oval-shaped canals: a micro-comp...

The present study aimed to evaluate adaptation of the single gutta-percha cone on root canal walls prepared with the two systems, the XP-endo Shaper (XPS; FKG Dentaire, La Chaux-de-Fonds, Switzerland) and ProTaper Next systems (PTN; Dentsply Sirona, Ballaigues, Switzerland) by using micro-computed tomography (micro-CT) technology. Twenty long oval-shaped canals in mandibular incisors were scanned by micro-CT (S...

Morphometric analysis of inferior incises through computerized microtomography

Studies on dental anatomy and internal morphology of the root canal system are important to optimize endodontic therapy. Knowledge of variations in the number of channels, number of roots, horizontal dimensions and channel width increase the understanding and mastery of the anatomy for the clinician. The present study aims to describe the morphometric analysis of lower incisors through computerized microtomogra...

The effect of high concentration of zoledronic acid on tooth induced movement a...

Zoledronic acid (ZA) is often prescribed for osteoporosis or resorptive metabolic bone disease. This study aims to evaluate the effect of ZA on orthodontic tooth movement (OTM) and root and bone resorption and its repercussion on root, periodontal ligament and alveolar bone tissues. The experimental group consisted of 72 Wistar rats divided in four subgroups: Naive, Saline and Zoledronic Acid groups at the conc...

Efeito da profilaxia semanal no desenvolvimento "in situ" de lesão cariosa em d...

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciencias da Saude; Avaliação do efeito da remoção regular de placa dental no desenvolvimento in situ de lesão cariosa dentinária em indivíduos residentes numa área com água fluoretada e consumidores de dentifrício fluoretado. Os resultados mostraram que nos espécimes que receberam profilaxia com pedra pomes a superfície dentária mostrou-...

Effects of Cymbopogon winterianus Jowitt ex Bor essential oil on the growth and...

Trichophyton mentagrophytes is a fungus causative agent of dermatophytosis, affecting humans worldwide. This has driven the search for products for the treatment of these infections. Accordingly, the aim of this study was to investigate the antifungal activity of the Cymbopogon winterianus essential oil against T. mentagrophytes. The antifungal tests consisted of antifungal screening, determination of MIC and M...

Efficacy of Origanum essential oils for inhibition of potentially pathogenic fungi

This study aimed to assess the efficacy of O. vulgare L. and O. majorana L. essential oil in inhibiting the growth and survival of potentially pathogenic fungal strains and also sought to evaluate the possible mechanisms involved in the establishment of the antifungal property of the tested essential oils through assays of osmotic stability and morphogenesis. Test strains included in this study were Candida alb...
