Determination of The Combined Mesio-Distal Widths of The Permanent Mandibular Incisors and That of The Maxillary and Mandibular Canines and Premolars in a Group of Egyptian Children in Rural Areas of Sohag Governorate: A Cross Sectional Study
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.
