A study of 525 3–4‐year‐old children in nursery schools and day‐care centres was carried out to assess occlusal relationships and the presence of spacing or crowding of teeth. No significant differences in occlusal relationships were found between boys and girls ( P > 0·05). Bilateral straight terminal planes of molars and class 1 canine relationship were the most prevalent features (74·5% and 73·3% respectively). Most of the children had ‘normal’ vertical and transverse occlusal relationships. The most common sites of spacing were mesial to maxillary canines and distal to mandibular canines. 32% of the children were found to have generalized anterior segment spacing, 4% showed exclusively anthropoid spaces, and 18% had either contact between all the teeth or crowding in the anterior region.
