Association of congenital missing of maxillary lateral incisors with cervical vertebral body fusions and/or atlas posterior arch deficiency.

ABSTRACT: To evaluate the association between congenital missing of maxillary lateral incisor (MLI) with cervical vertebral body fusions, posterior arch deficiency, and both anomalies. A total of 64 subjects (24 males and 40 females; mean age 16 ± 4.5 years) were detected to have congenital missing of MLI and selected as a study group. Two hundred and fifty-six subjects (87 males and 169 females, mean age 18.1 ± 3.2 years) were assigned to the control group. In the congenital absence of MLI, 53.7% revealed cervical column body fusion, 11.1% indicated a posterior arch deficiency, and 9.3% showed cervical column body fusion with posterior arch deficiency. Morphological deviations of the cervical column showed significant associations with congenital absence of MLI compared to control group (p <
