N2 - AIM: Agenesis of maxillary permanent canines is a rare form of agenesis (prevalence 0.07-0.13%). The aetiology is still unknown. The purpose was to focus on dentitions and craniofacial profiles in individuals with maxillary canine agenesis.METHOD: From 91 individuals (10-18 years of age) 91 Orthopantomograms and 77 profile radiographs were divided accordingly: Group I: agenesis of 1 or 2 maxillary canines. Group II: several ageneses including the maxillary canines. Dentition analysis included crown/root shape, invaginations, eruption disturbances and resorption patterns. Cephalometric angular measurements and mutual comparisons between the groups were performed. Agenesis pattern in Group II was compared to agenesis pattern in a population of children and young adults not characterized by maxillary canine agenesis. Cephalometric values from both groups were compared to normal values from individuals without agenesis. Findings were statistically evaluated.RESULTS: Dentition: Group I: only the missing maxillary canines were deemed to be in an abnormal dental deviation. Group II: abnormal dental development regarding morphology, resorption of primary teeth and also agenesis of the first maxillary premolar. Comparison of the groups showed a difference in the pattern of malformation. Profile: Group I: anterior inclination of the maxilla and increased cranial base angle were significant findings. Group II: diminished incisor slope in the maxilla and enlarged cranial base angle were significant findings. A comparison showed a difference in maxillary inclinations of the teeth.CONCLUSION: Group I dentitions are normally developed with only minor dental malformations. Group II dentitions had several dental malformations and often agenesis of the first maxillary premolar. Significant findings: first maxillary premolar agenesis in Group II and enlarged cranial base angle in both groups.
