Brief summary

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.
