Detailed Description

Study Settings:

  • Students will be randomly selected from preparatory schools in rural areas of Sohag governorate, seated in the school lap or an empty classroom.
  • Clinical examination will be made in the daylight using disposable diagnostic sets (mirror, and explorer). No diagnostic radiographs will be taken.
  • Operator: Master degree's student in Pediatric Dentistry and Dental Public Health.
  • Full mouth alginate impression will be taken and study models will be poured within one hour with hard dental stone for each subject.
  • Mesio-distal widths of both maxillary and mandibular permanent incisors, canines, first and second premolars will be measured from the study models using digital caliper according to the method described by(Moorrees & Reed, 1964) by measuring the greatest distance between the contact points on the proximal surfaces holding the caliper parallel to both occlusal and vestibular surfaces of the tooth.
