FOGORVOSI SZEMLE ■ 97. évf. 2. sz. 2004.

Antibakteriális hatású, elősegíti a gyulladt periapikális szövetek gyógyulását. A gyökércsatornában lévő baktériumok 99,9%-át elpusztítja [8]. Állatkísérletek igazolták, hogy Escherichia coli LPS fertőzést is képes a gyökércsatornában hatástalanítani [36]. A gyógyulás az apikális gyökérhártya nem differenciált mesenchymális sejtjeinek stimulációjából ered, elősegítve a cementogenezist [20,10]. Az apexifikáció következtében létrejött apex szövettanilag leggyakrabban cementszerű anyag [6]. Ha élő pulpaszövet marad a gyökércsatornában, szabálytalan formájú dentin is zárhatja a gyökércsúcsot [6].

A Ca(OH)2 paszta alkalmazásával a periapikális gyógyulás és a gyökércsúcs záródása az esetek 79-96%ában következtek be. A guttapercha töméssel ellátott, előzőleg Ca(OH)2 pasztával kezelt fogak 92%-a négy évvel később sem mutatott patológiás elváltozást a kontroll röntgenfelvételen [17],

Összefoglalva: irodalmi adatok és saját tapasztalataink alapján a még fejlődésben lévő elhalt maradó fogak kezelésére legalkalmasabbnak ideiglenes gyökértömésként a Ca(OH)2 pasztát, végleges gyökértömésként a gyökércsúcs záródása után a „félig melegített guttapercha gyökértömést” tartjuk.
