Prevalence of spaced and closed dentition and its relation to malocclusion in primary and permanent dentition.

An ideal primary dentition is the indicator of future ideal permanent dentition. Absence of primate or secondary spaces in the primary dentition is expression of disproportion between jaw/tooth sizes. Little information is known on the relationship of spacing and closed dentition with malocclusion in relation to primary and permanent dentition. Hence, the present study was conducted to find the relationship of spacing and closed dentition with malocclusion in primary and permanent dentition in children during their deciduous dentition period.
