[Determination of required space for canine and premolar eruption in mixed dentition using mesiodistal width of mandibular incisors]

ABSTRACT

Background and Objective: Determination of the relation between periphery of dental arch and teeth size which mostly done before eruption of some permanent teeth, is of important levels of diagnosis in mixed dentition. Determination of this relationship is not possible without prediction and distinct evaluation of unerupted permanent mesiodistal width [Permanent canines and premolars]. The aim of this study was to evaluate the required space for eruption of canine and premolars using total width of lower incisor in Iranian people by Tanaka and Johnston method:
