Summary Excerpt Details

Los adhesivos universales que se utilizaron para el estudio fueron Scotchbond Universal (3M ESPE), All-Bond Universal (Bisco), Gluma Bond Universal (Heraeus Kulzer), Tetric N-Bond Universal (Ivoclar-Vivadent), Futurabond U (VOCO), Peak Universal Bond (Ultradent) y un adhesivo convencional de cuarta generación OptiBond FL (Kerr) que se utilizó como grupo control, todos disponibles en México. Para el estudio se obtuvieron y almacenaron en agua destilada 70 órganos dentarios posteriores de dentición permanente de ser humano libres de caries, a los cuales se les realizaron dos cortes con un disco de diamante, primero se cortaron en sentido transversal, dividiendo a los dientes en dos partes; coronas y raíces, después a las coronas se les realizó un corte longitudinal de mesial a distal para obtener dos mitades de las coronas, las que luego fueron insertadas en resina poliéster, después se recortaron y pulieron, se lijó la superficie de la dentina durante un minuto realizando movimientos en forma de ocho, posteriormente se realizaron los procedimientos adhesivos según las indicaciones de cada fabricante, y se colocó un fragmento de resina compuesta (FiltekTM Z350 XT, 3M ESPE, St. Paul, Minnesota, USA) con la ayuda de un molde de plástico de forma “bite ramp” (rampa de mordida). Dichas muestras se almacenaron en agua destilada durante 24 horas en una incubadora a 37.5°C, antes de someterlas a la prueba de laboratorio en la maquina universal de ensayos (Autograph AGS-X, Shimadzu Co, Tokio, Japón).

    Zielsetzung und Themenschwerpunkte

    Die vorliegende Arbeit befasst sich mit der in-vitro-Bewertung der Scherfestigkeit von sechs verschiedenen universellen Adhäsivsystemen in Dentin. Die Untersuchung zielt darauf ab, die Wirksamkeit und Leistungsfähigkeit dieser Systeme im Hinblick auf die Bildung einer stabilen und dauerhaften Bindung an die Zahnsubstanz zu vergleichen.

    • Scherfestigkeit verschiedener universeller Adhäsivsysteme
    • Vergleich der Adhäsionsmechanismen in Dentin
    • Einfluss von Oberflächenvorbereitungstechniken auf die Adhäsionsqualität
    • Bewertung der klinischen Relevanz der Ergebnisse für die restaurative Zahnheilkunde
    • Bewertung der langfristigen Stabilität der Adhäsion

    Zusammenfassung der Kapitel

    Kapitel 1 führt in das Thema der Adhäsion in der Zahnheilkunde ein und beleuchtet die historische Entwicklung sowie die verschiedenen Arten der Adhäsion. Kapitel 2 befasst sich mit grundlegenden Prinzipien der Adhäsion, einschließlich Oberflächenenergie, Oberflächenspannung, Benetzung, Kontaktwinkel, Adsorption und klinischen Faktoren, die die Adhäsion beeinflussen. Kapitel 3 bietet einen Überblick über die Eigenschaften von Zahnsubstraten, einschließlich Schmelz, Dentin und Zement.

    Kapitel 4 behandelt die Mechanismen der Adhäsion an Zahnsubstraten, einschließlich der Bildung von Resintanbindungen in Schmelz und Dentin sowie der Rolle des Dentinschmierfilms. Kapitel 5 diskutiert verschiedene Adhäsionstechniken, wie z.B. Säureätzung von Schmelz und Dentin, selbstätzendes Adhäsiv und selektives Säureätzen von Schmelz. Kapitel 6 bietet eine Klassifizierung von zahnärztlichen Adhäsivsystemen basierend auf ihrer Adhäsionsstrategie.

    Schlüsselwörter

    Universales Adhäsivsystem, Scherfestigkeit, Dentin, Schmelz, Säureätzen, Selbstätzendes Adhäsiv, Adhäsionsmechanismus, klinische Relevanz, Restaurative Zahnheilkunde.
