Digital Analysis of Primary Teeth Crown Dimensions and Clinical Evaluation in a Sample of Egyptian Children

Digital Analysis of Primary Teeth Crown Dimensions and Clinical Evaluation in a Sample of Egyptian Children

The aim of this study will be conducted to:

1. Digitally determine crown dimensions of primary teeth in a sample of Egyptian children.
2. Clinical evaluation of prefabricated zirconia crowns according to the Egyptian sizes compared with the international standard zirconia crowns sizes for primary upper central incisors

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.

• Sound interproximal & buccal / lingual walls with or without minimal occlusal pits & fissure incipient caries.
• No previous interproximal & buccal / lingual restorations.
• Intact mesial and distal marginal ridge.

Exclusion Criteria:

• Children with gross carious lesions.
• Children with hypo-mineralization, hypoplasia and fracture primary teeth.
• Children with medical disabilities
