A fogorvosi anyagok optikai vizsgálatának módszerei
Transzlucencia és fedőképesség
Absztrakt
Bevezetés: A fogászati restaurációk esztétikai minősége nagymértékben függ az alkalmazott anyagok optikai tulajdonságaitól,
különösen az áttetszőségtől (transzlucencia) és az opacitástól.
Célkitűzés: Összefoglalónk célja az áttetszőség és opacitás mérési módszereinek bemutatása, beleértve a Kubelka–
Munk-egyenletet és spektrális transzmittancia és reflektancia vizsgálatokat, valamint azok klinikai alkalmazását fogászati
anyagok esetében.
Vizsgálati anyag és módszer: A kontrasztarány (CR, Contrast Ratio) és az áttetszőségi paraméter (TP, Tranclucency
Parameter) kulcsfontosságú mérőszámok ezen tulajdonságok kvantitatív értékelésében. A CR az anyag fedőképességét
jellemzi fekete és fehér háttér előtti fényvisszaverési arány alapján, míg a TP az anyag fényáteresztő képességét
határozza meg a CIE (Commission Internationale de l’Eclairage, Nemzetközi Világítástechnikai Bizottság) színtérben
számított színkülönbségek alapján.
Összegzés: Az eredmények alapján e módszerek kombinált alkalmazása lehetővé teszi az anyagok optikai tulajdonságainak
pontosabb értékelését, segítve a klinikai anyagválasztást és a restaurátumok esztétikájának optimalizálását.
