  1. DENTAL MATERIALS AND TECHNOLOGYFilling materials and adhesive technologiesDental cements andendodonticmaterialsDr. Zsolt Zalai

  2. The aims of filling a teeth • torepairtheshortage of substance • torestorethemasticatoryfunction • suitableanatomicform • aesthetics

  3. The idealfillingmaterial • no irritationagainstthepulportheperiodontalattachment • minimalabrasion • protectsthepulpagainstheat, physical and chemicaleffects • cariesprotectiv • minimalsettingcontraction and expansion • aesthetics (colour, transparency) • chemical and physicalcontacttotheenamel/dentin • simplyapplication • cheap

  4. Classification • Aims of using • Basefillings • Temporaryfillings • Permanentfillings • Plastic • Inlay

  5. Fillings • Plastic • amalgam • cements • composite • Inlays • metallic • ceramic • metallo-ceramic • composite

  6. Amalgam Content: liquidmercury and an alloypowder of mostlysilver, and somecopper Advantage: easytoadapttocavitywalls longlasting lowercosts Disadvantage: no protectionagainstheat notaesthetic corrosion no chemicaladhesionbetween theteeth and amalgam settingexpansion (0.2%)

  7. Cements Cementscan be classifiedbasedonthetype of theirmatrix: Phosphate Polycarboxylate (zincpolycarboxylate, glassionomer) EBA Resin Indications: crown, bridge, inlaycementation corebuild-ups post cementation base and liningmaterial temporaryfillings semi-permanentfillings

  8. GIC=Glass Ionomer Cement

  9. GIC+ Phosphate cement

  10. GIC Sealing of pits and fissures

  11. Composite fillings Advantages chemicaladhesiontothesurface of theenamel and dentine widerange of toothcolours-aesthetics suitableforMinimallyInvasivedentistry require less removal of toothstructure less sensitiveto hot and cold Disadvantages technique-sensitive expensive shrinkage (1,5-3%)

  12. How to make a composite filling? Choosecolour Anesthesia Cleanthecavity Isolation Desinfection Lining Useadhesive Polimerization of theadhesive Placethematerial Polimerization of thecomposite Finishing, polishing Checktheocclusion

  14. Endodontics

  15. Root canal treatment Removing the caries and opening the teeth Removing the pulp chamber Cleaning the root canal with files, solutions Dried with paper points Filling with gutta percha

  18. Sealers • Cink-oxid-eugenol (Tubliseal, Endoseal) • Poli-keton (Diaket) • Epoxi-resin (AH26, AHPlus) • Glassionomer (Ketac-Endo) • Dentinadhesive (Epiphany) • Formaldehid asingredient (Endomethasone, N2) • Materialscontainingmedicaments (CRSC, Sealapex, Apexit)

  20. Root filling by vertical condensation

  21. Endodontictreatment Opening the teeth Including:Blood vessels, nerves, pulp tissues
