Abstract EN
Background : This study was done to assist bond strength, X-ray diffraction and biocompatibility of manufactured dental base materials from enamel powder and synthetic hydroxyapatite with or without CO2 laser treatment.
Materials and methods : The bond strength was detected by construction cylinders from the manufactured base materials constructed on exposed dentine of human extracted premolar teeth and by Zwick’s universal testing machine, the powder of the manufactured base materials were used to get X-ray diffraction pattern by X-ray diffraction machine and for biocompatibility test.
A polyethelen tubes containing the manufactured base materials were implanted on the dorsal submucosal site of Rabbit’s tissues and histopathological slides were prepared for histopathological study.
Results : The results showed that the manufactured base material that contains mixture of enamel powder or/and hydroxyapatite with or without CO2 laser treatment has bond strength to dentine .X-ray diffraction test showed that the zinc hydrogen phosphate(ZnH2PO7) was appeared in the final products of the set new base materials without CO2 laser treatment and this product disappeared with CO2 laser treatment.
The Xray diffraction test showed that all elements of base materials react with each other.
The histopathological test showed mild irritation to rabbit’s tissue by the manufactured base material this irritation subsided with time.
.
Conclusion : The manufactured base materials have bond strength to dentine and the base material that contains synthetic hydroxyapatite has higher bond strength to dentine and the manufactured base materials were biocompatible with Rabbit’s tissues.
