• Conditions: Primary Teeth Crown Dimensions in a Sample of Egyptian Children

• Registration Number: NCT06874218
• Lead Sponsor: Tanta University

Brief Summary

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

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
crown dimensions of primary teeth in a sample of Egyptian children.	intra operative	Digitally determine crown dimensions of primary teeth in a sample of Egyptian children using intraoral scanner and Digital measurements of teeth dimensions by Meshmixer analyzing software.

Secondary Outcome Measures

Name	Time	Method
Clinical evaluation of prefabricated zirconia crowns according to the Egyptian sizes compared with the international standard zirconia crowns sizes for primary upper central incisors.	intra operative	Clinical evaluation of prefabricated zirconia crowns according to the Egyptian sizes compared with the international standard zirconia crowns sizes for primary upper central incisors by Modified United States Public Health Service (USPHS) criteria, and the gingival state near the primary performed crown will be assessed by using the Silness\& Loe indices (1964) to record plaque index and gingival index.
