Closed coil spring dan elastomeric chain merupakan aksesoris ortodonti yang sering digunakan untuk menghasilkan force dalam menggerakan gigi. Dimana kedua tersebut memiliki sifat degradasi struktur disebabkan oleh beberapa faktor seperti pH, suhu flouride Minuman berkarbonasi minuman mengandung gas karbon dioksida. Karbon dioksida bahan acidifier menjadikan tingkat keasaman sehingga meningkatka...

The objective of this in-vitro study is evaluation remineralization potential three agents- Tricalcium phosphate flouride(TCP-F), Calcium sucrose phosphate(CaSP), Casein phosphopeptide- amorphous calcium phosphate(CPP-ACP) in artificial enamel lesion using laser fluorescence based DIAGNOdent(KaVo). 30 single rooted premolars were selected. Samples randomly divided into 3 groups with 10 samples ...

Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers of the electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membrane containing a liquid electrolyte. The two outer layers of PPy are each connected with gold electrodes and separated by the porous PVDF membrane. This mi...
