Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
The combined mesio-distal widths of the permanent mandibular incisors, the maxillary canines, mandibular canines and premolars.
using Digital Caliper the data will be recorded in Millimeter.
Measured: one weak
