About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Children having normal fully erupted primary teeth and with no morphological variations.
  • Children with no history of orthodontic or prosthodontic treatment.
  • Children with normal overjet and overbite.
  • 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

Treatment and study plan

prefabricated CAD-CAM Zirconia crowns according to Egyptian sizes.

Device

compare prefabricated zirconia crowns according to the Egyptian crown sizes with the international standard zirconia crowns sizes for primary upper central incisors

Primary outcomes

  1. crown dimensions of primary teeth in a sample of Egyptian children.

    Time frame: 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 outcomes

  1. Clinical evaluation of prefabricated zirconia crowns according to the Egyptian sizes compared with the international standard zirconia crowns sizes for primary upper central incisors.

    Time frame: 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.
