[Clinical analysis and treatment of 68 spaced dentition cases]

One of the characteristic feature of normal occlusion is arch continuity, as expressed by proximal contact between all teeth in each dental arch.The dental arches of a consider able number of individuals show space between some,or even all,of the teeth.Such dental arches are know as spaced dentition.It is detrimental of arch integrity, esthetics and normal dental function.The purpose of this article to study distribution according to sex and age,number and location of the spaces,their etiology and principle of orthodontic treatment.In a random sample of 68 cases of the participating patients who is space greater than 0.5 millimeter between the proximal surface of adjacent teeth.The samples were divided into three age groups, the exact width of each space was measured by calipers in table.
