Eruption of the permanent maxillary canines in relation to mandibular second molar maturity

Abstract

Objective: To evaluate the timing of spontaneous maxillary canine eruption in relation to stages of mandibular second molar maturation. Potential confounding effects from such factors as age, growth phase, and facial features were also explored. Subjects and Methods: A sample of 106 healthy subjects (48 females and 58 males; age range, 9.4-14.3 years) with both permanent maxillary canines during the final phase of intraoral eruption were included. Mandibular second molar maturation (stages E to H) was assessed according to the method of Demirjian. Skeletal maturity was determined using the cervical vertebral maturational (CVM) method. Facial vertical and sagittal relationships were evaluated by recording the SellaNasion/mandibular plane (SN/MP) angle and the ANB angle. An ordered multiple logistic regression was run to evaluate adjusted correlation of each parameter with the mandibular second molar maturational stage. Results: Overall, the prevalence of the different second molar maturational stages was 36.8%, 37.8%, and 27.4% for stages E, F and G, respectively. According to the regression model, this relation was not influenced by sex, CVM stage, SN/MP angle, and ANB angle. Conclusions: Irrespective of sex, growth phase, and facial features, the maturational stage of the mandibular second molar may be a reliable indicator for the timing of spontaneous eruption of the maxillary canine.

Evaluation of Maxillary Canine Calcification and Skeletal Maturity Comparing Males and Females Subjects in Different Facial Heights

“…Several studies have assessed the relationship between facial heights and skeletal maturity. 5,12,13,15,16 This study evaluated skeletal maturity and dental maturity and compared them in low-angle and high-angle females and males. The groups of this study were categorized based on the mandibular plane angle, because the mandibular plane angle is a simple and reliable analytical tool.…”

“…12,14 Moreover, it is also known that there is a relationship between vertical growth direction and skeletal maturity. 5,12,13,15,16 Baccetti et al 5 stated that eruption of teeth completed an earlier stage in hyperdivergent subjects. Perinetti et al 15 also found that patients with a vertical facial type had earlier dental maturation.…”

Perinetti et al 15 also found that patients with a vertical facial type had earlier dental maturation. Nanda 16 reported that the growth spurt period was faster in an open-bite group than in the deep-bite group.…”

Intérêt de la méthode de maturation des vertèbres cervicales (CVM) en orthopédie dento-faciale : mise au point

“…C'est dans ce contexte que la méthode de maturation des vertèbres cervicales (CVM) a été initialement introduite par Lamparski (1972) pour l'évaluation de la maturation squelettique, en exploitant une simple téléradiographie de profil faisant partie du bilan orthodontique standard [1,7]. Actuellement, la méthode CVM est largement répan-due en orthodontie, et suscite un intérêt majeur de la part des cliniciens dans l'évaluation de la maturation squelettique [1,[8][9][10][11][12][13]. Ce travail a pour objectif d'apporter une mise au point sur la méthode CVM afin de montrer son intérêt par rapport à la méthode de radiographie de la main.…”

Periodontal status of buccally and palatally impacted maxillary canines after surgical-orthodontic treatment with open technique

“…Transverse maxillary deficiency is associated with maxillary canine impaction (6)(7)(8); thus, early interceptive orthodontic treatment with rapid maxillary expansion is effective in increasing the eruption rate of displaced maxillary canines (9)(10)(11). In the absence of such treatment, maxillary canine impaction requires comprehensive orthodontic-surgical treatment, including surgical exposure of the canine crown and orthodontic traction to bring the impacted canine into occlusion (12)(13)(14).…”
