Title Extracting Deciduous Canines And First Molars May Prevent The Ectopic Eruption Of Impacted Permanent Maxillary Canines
Clinical Question In subjects with an impacted maxillary permanent canine, does extracting deciduous canines and first molars prevent the ectopic eruption of maxillary permanent canines compared to no treatment at all?
Clinical Bottom Line For patients with an impacted maxillary permanent canine, extracting deciduous canines and first molars is more effective than no treatment in reducing the likelihood of ectopic eruption of the permanent canine.

#1) 21392685Bonetti/2011Subjects at risk for canine impaction or resorptionRandomized control trial
Key resultsRadiographically: The inclination of the maxillary canine showed statistically significant changes between the initial observation (T0) and 18 months later (T1) when comparing the ECMG (extraction of deciduous canine and molar) with the ECG (extraction of deciduous canine; p=.0001) and the CG (no extraction; p=.0001). The position of the crown showed an improved mesio-distal position of 1 or 2 sectors that exhibited a statistically significant change when comparing the ECMG with the ECG (p=.0009) and the CG (p=.003). Clinically, a statistically significant difference (p=.036) was observed in favorable outcomes between the ECG (78.6%) and the ECMG (97.3%).

Comments on
The Evidence
The study used a randomized control trial with similar groups at the beginning that were treated the same. It reported a completion rate of higher than 80%, with adequate follow up and compliance of the subjects. It reported a double-blind study, and recall bias did not apply to these studies. There was no statement provided regarding competing interests in the study.
Applicability Extracting the deciduous canine and first molar is within the capability of a general dentist and is likely to be accepted by the average patient to aid in the prevention of ectopic eruption of maxillary canines.
