Aim: This prospective randomized clinical study was aimed to assess the eruption of palatally displaced canines (PDC) in subjects treated with rapid maxillary expansion (RME). Materials and Methods: A sample of 60 subjects in the early mixed dentition (7.6 to 9.6 years, prepubertal - CS1 or CS2) with PDC diagnosed on PA radiographs was enrolled in the trial. The 60 subjects were randomly allocated to the treatment group (TG, 35 cases, treated with RME) or the no-treatment group (NTG, 25 cases). At T2 (early permanent dentition, postpubertal, CS4 or CS5), the prevalence rate of successful or unsuccessful eruption of the upper canines was compared in TG versus NTG (chisquare analysis, P < .05). The measurements on PA and panoramic films at T1 were compared in TG versus NTG by the Mann-Whitney U test (P < .05). Results: The number of dropouts from T1 to T2 was three subjects in both the TG and NTGs. No statistically significant differences were found for any variable at T1. The prevalence rate of successful eruption of the maxillary canines was 65.7% (21 subjects) in the treated group, whereas it was 13.6% (three subjects) in the untreated control group. The comparison was statistically significant (CHI2 = 12.4; P < .001). Subjects with palatally displaced canines in the early mixed dentition do not exhibit a transverse deficiency of the maxillary arch. Conclusion: RME in the early mixed dentition is an effective treatment modality to increase the rate of eruption of PDCs

Abstract

Aim: This prospective randomized clinical study was aimed to assess the eruption of palatally displaced canines (PDC) in subjects treated with rapid maxillary expansion (RME). Materials and Methods: A sample of 60 subjects in the early mixed dentition (7.6 to 9.6 years, prepubertal - CS1 or CS2) with PDC diagnosed on PA radiographs was enrolled in the trial. The 60 subjects were randomly allocated to the treatment group (TG, 35 cases, treated with RME) or the no-treatment group (NTG, 25 cases). At T2 (early permanent dentition, postpubertal, CS4 or CS5), the prevalence rate of successful or unsuccessful eruption of the upper canines was compared in TG versus NTG (chisquare analysis, P < .05). The measurements on PA and panoramic films at T1 were compared in TG versus NTG by the Mann-Whitney U test (P < .05). Results: The number of dropouts from T1 to T2 was three subjects in both the TG and NTGs. No statistically significant differences were found for any variable at T1. The prevalence rate of successful eruption of the maxillary canines was 65.7% (21 subjects) in the treated group, whereas it was 13.6% (three subjects) in the untreated control group. The comparison was statistically significant (CHI2 = 12.4; P < .001). Subjects with palatally displaced canines in the early mixed dentition do not exhibit a transverse deficiency of the maxillary arch. Conclusion: RME in the early mixed dentition is an effective treatment modality to increase the rate of eruption of PDCs
