Core Tip
Core tip: Tooth agenesis and craniofacial morphology was examined in non syndromic children with upper cervical spine morphological deviations. No significant differences in tooth agenesis and craniofacial morphology were found between children with and without upper spine morphological deviations, but a non-significant tendency of a different tooth agenesis pattern between the groups was seen. In the total group significant associations between tooth agenesis and craniofacial morphology were found. A different aetiology for tooth agenesis in children with morphological deviations in the upper spine was suggested. The results may be valuable for the early diagnosis and treatment planning of non syndromic children with tooth agenesis.
