The purpose of this study was to analize or assess relationship between periodontal disease and crowding of the lower anterior teeth in Mix Dentition.
The results were as follows :

2.The technique of tooth brushing the plaque removal affected oral higine index.
3.The lowest point of cervical margin on plaster cast should high position on the crowding group in compared with the non-crowding group.
