La evolución de la adhesión a dentina
2004
-Isabel.Camps@uv.es Se realiza una revisión a la historia de la adhesión comenzando en las culturas precolombinas ("era pre-adhesiva"), para continuar en la "era adhesiva" con las aportaciones de Buonocuore y la aparición del Bis-GMA, pasando por la incorporación al mercado dental de los fosfatos, los oxalatos, el sistema Gluma. Se analiza también la descripción la capa híbrida por Nakabayashi, después aparecen los primers acuosos y la hibridación de tejidos duras hasta llegar a los sistemas adhesivos autograbadores. An overview of dentin bonding history is done by the author since early south American cultures (pre-adhesive age) to continued in the adhesive age with Buonoccore's findings a…
Akomodācijas viegluma testa aprobācija datorizētajam redzes skrīningam
2022
Darbs ir uzrakstīts latviešu valodā uz 42 lapaspusēm. Tas satur 14 attēlus, 7 tabulas, 48 atsauces uz literatūras avotiem. Maģistra darba mērķis bija salīdzināt akomodācijas viegluma mērījumus ar elektronisko iekārtu un klasisko mērīšanas metodi. 79 dalībniekiem (vidējais vecums 22 ± 5 gadi) tika veikts akomodācijas viegluma mērījuma ar standarta metodi, ar rokas flipera datorizēto metodi un 37 no 79 dalībniekiem automatizētā flipera datorizēto metodi. Testiem tika izmantotas ± 2 D lēcas, kas tika mainītas binokulāri, testa attālums 40 cm, bet testu ilgums 1 minūte. Automatizētā flipera datorizētā metodē dalībnieks testu veica ar iekārtu, kas tika uzvilkta dalībniekam uz galvas, lēcas acu p…
Clinical Evaluation of self and professionally applied desensitizing agents in relieving dentin hypersensitivity after a single topical application: …
2013
Objectives: The objective of this study is to evaluate the efficacy of self and professionally applied desensitizing agents in relieving dentinal hypersensitivity after single direct topical application. Study Design: This was a randomized controlled trial conducted among 57 patients. 8% Arginine paste was self- applied by the subject and Gluma desensitizer was applied by investigator. Numeric rating scale was used to mea - sure hypersensitivity after tactile stimulus, Schiff scale was used for cold and air blast stimuli respectively. Scores were recorded at baseline, immediately, 15 and 30 days after the application. Friedman, Wilcoxon test as post hoc was used to analyze within group diff…
Marginal integrity of different resin-based composites for posterior teeth: an in vitro dye-penetration study on eight resin-composite and compomer-/…
2002
Abstract Objective: To determine improvements in marginal adaptation of resin-based composite restorative systems by means of flow-composites (Solitaire 2/Gluma Solid Bond, Solitaire 2/Flow Line/Gluma Solid Bond, Point 4/Optibond Solo Plus, Point 4/Revolution/Optibond Solo Plus) and to determine the equality of simplified bonding systems (Solitaire 2/Gluma Comfort Bond, Tetric Ceram/Tetric Flow/Excite, Dyract AP/Prime & Bond NT/NRC, Pertac II/Prompt-L-Pop) in marginal gap formation. Methods: The marginal dye penetration (2% methylene-blue) was investigated separately for the approximal boxes of Class II mod-cavities with one cervical margin of the approximal box within enamel, the other wit…
Decoding the Folding of Burkholderia glumae Lipase: Folding Intermediates En Route to Kinetic Stability
2012
The lipase produced by Burkholderia glumae folds spontaneously into an inactive near-native state and requires a periplasmic chaperone to reach its final active and secretion-competent fold. The B. glumae lipase-specific foldase (Lif) is classified as a member of the steric-chaperone family of which the propeptides of alpha-lytic protease and subtilisin are the best known representatives. Steric chaperones play a key role in conferring kinetic stability to proteins. However, until present there was no solid experimental evidence that Lif-dependent lipases are kinetically trapped enzymes. By combining thermal denaturation studies with proteolytic resistance experiments and the description of…
