简要总结
The aim of this study will be conducted to:
- Digitally determine crown dimensions of primary teeth in a sample of Egyptian children.
- Clinical evaluation of prefabricated zirconia crowns according to the Egyptian sizes compared with the international standard zirconia crowns sizes for primary upper central incisors
详细描述
Currently, there is limited availability of primary tooth crown measurement for Egyptian children. SO, this study aims to digitally determine tooth crown dimensions of primary teeth in a group of Egyptian children and compare prefabricated zirconia crowns according to the Egyptian crown sizes with the international standard zirconia crowns sizes for primary upper central incisors.
