Extraction of the deciduous canine as an interceptive treatment in children with palatal displaced canines—part I: shall we extract the deciduous canine or not?

Space conditions, palatal vault height, and tooth size in patients with and without palatally displaced canines: A prospective cohort study

“…Patients in the UPDC (mean age, 11.8 6 1.0 years) and BPDC groups (mean age 11.3 6 1.0 years) were collected from a previously published prospective randomized clinical trial evaluating the effect of interceptive extraction of the deciduous canines. 2 Patients were consecutively recruited from public dental clinics in Gothenburg, Västra Götaland County Council, Sweden, between September 2008 and January 2011. The inclusion criteria were Caucasians aged 10-13 years with either UPDC or BPDCs and persisting deciduous canine(s).…”

“…1 Therefore, early diagnosis and interceptive measures are associated with better treatment prognosis. Some interceptive procedures presented in the literature are extraction of deciduous canines [2][3][4][5] only or, in addition to placement of a transpalatal bar, expansion of the maxilla, 6 and preservation or lengthening of the dental arch length by means of extraoral traction. 7 Two major theories have been proposed to explain the etiology of palatally displaced canines (PDCs): guidance theory and genetic theory.…”

Association between Ectopic Mandibular and Maxillary Canines

“…29 Patients with previous or current orthodontic treatments were excluded, since such treatments may resolve the impaction and ectopia via interceptive treatment, and these treatments are suggested at an earlier age. [6][7][8] Moreover, missing lateral incisors could influence the path of eruption of the permanent canines. 30 The presence of labial crowding makes canine measurements challenging because the overlapped teeth and facial asymmetry make establishing the true horizontal difficult.…”

“…4 Early assessment of impacted/ ectopic canines is of great importance as early intervention could decrease the likelihood of impaction and reduce the chances of unfavorable outcomes. [5][6][7][8] Impacted maxillary canines have been reported in 1 to 2% of the population. [9][10][11] Although it is not common, any failure to diagnose and treat impacted maxillary canines early may increase the risk of unfavorable sequelae, 12 such as resorption of the lateral incisor root, cyst formation, 13 and internal resorption of the impacted tooth.…”

Risk of developing palatally displaced canines in patients with early detectable dental anomalies: a retrospective cohort study

“…Conversely, when there is an early orthodontic diagnosis of PDC, simpler clinical approaches such as deciduous canine extraction and rapid maxillary expansion can lead to spontaneous canine eruption in a high percentage of children 3 , 5 , 23 , 30 . These early approaches can prevent canine impaction, incisor root resorption, and collateral effects related to tooth traction.…”
