Abstract
Statistical association of crowding and spacing with age, sex, orthodontic treatment and extractions finds a tendency for more maxillary posterior spacing in males and more lower anterior spacing in females. Extractions were also associated with spacing. No association was found between spacing and orthodontic treatment.
