ABSTRACT

Aim

To analyze the interrelationship between incisor width, deviations in the dentition and available space in the
dental arch in palatally and labially located maxillary ectopic canine cases.

Methods

Size: On dental
casts from 69 patients (mean age 13 years 6 months) the mesiodistal widths of each premolar, canine and incisor were
measured and compared with normal standards. Dental deviations: Based on panoramic radiographs from the same patients
the dentitions were grouped accordingly: Group I: normal morphology; Group IIa: deviations in the dentition within the
maxillary incisors only; Group IIb: deviations in the dentition in general. Descriptive statistics for the tooth sizes and dental
deviations were presented by the mean and 95 confidence limits for the mean and the p-value for the T-statistic.
Space: Space was expresses by subtracting the total tooth sizes of incisors, canines and premolars from the length of the
arch segments.

Results

Size of lateral maxillary incisor: The widths of the lateral incisors were significantly different in
groups I, IIa and IIb (p=0.016) and in cases with labially located ectopic canines on average 0.65 (95 CI:0.25-1.05,
p=0.0019) broader than lateral incisors in cases with palatally located ectopic canines. Space: Least available space was
observed in cases with labially located canines. The linear model did show a difference between palatally and labially located
ectopic canines (p=0.03). Space related to deviations in the dentition: When space in the dental arch was related to dental
deviations (groups I, IIa and IIb), the cases in group IIb with palatally located canines had significantly more space compared
with I and IIa.

Conclusion

Two subgroups of palatally located ectopic maxillary canine cases based on registration of
space, incisor width and deviations in the morphology of the dentition were identified.
