“…Although several studies have reported that tooth maturation can be used as an indicator of development, tooth maturation has a relative relationship to the occurrence of peak mandibular growth. 11,12 This study also demonstrated that there is a difference of only 0.3 in the average of the CVM method and that of Demirjian's method, meaning that the standard deviation of the CVM method and Demirjian's methods also had a difference of only 0.45. Considering these results, it can be stated that no significant difference was found, and that it is necessary to retest this method.…”

Background: Malocclusion is one of the most familiar dental problems, with a high prevalence among the population. Understanding the patient’s craniofacial growth and development is crucial in diagnosis, as are the planning and subsequent success of the treatment. Malocclusion needs to be treated early to optimise the outcome achieved by the treatment. One of the most common types of malocclusions observed in clinics is crowding. The craniofacial bone relevant to the treatment of crowding is the mandible, defined as the mandibular length from the condylion to gnathion areas. When planning treatment, clinicians may experience difficulties in determining the biological age of patient, particularly when supporting diagnostic tools are not available. The indicators of biological age can be observed by the assessment of bone maturation using the cervical vertebrae maturation (CVM) method and by the analysis of tooth maturation using Demirjian’s method. However, limited studies are available regarding the accuracy of these methods as diagnostic tools. Purpose: This study aims to analyse the accuracy of the CVM method compared with Demirjian’s method concerning mandibular length growth. Methods: An analytic research method and a cross-sectional design are employed. The research sample comprised 50 lateral cephalometric and panoramic photos of children aged 8-16 years. Data were collected by analysing the maturity level of the cervical vertebrae and the teeth, and measuring the mandible length of the children in the photos. The statistical test used was the Wilcoxon test. Results: The results of the Wilcoxon test for the asymptotic sign had a p-value of 0.116 > 0.05, indicating no significant difference between the CVM and Demirjian methods. Conclusion: Both of the methods noted above yielded equally accurate results for determining mandibular length growth.

“…The panoramic radiography, an accessible exam to pediatricians and general dentists, has been alternatively used to determine craniofacial development according to dental calcification as it correlates to the growth pubertal stages [7][8][9][10], and it might guide timely patient referral to orthodontist [1,2]. Intra-and inter-examiner reproducibility of Nolla's [11] method was evaluated, and the tooth 33 had relatively larger reproducibility rates.…”

“…The orthopedic/ orthodontic treatment of children and adolescents must consider, amongst other factors, the appropriate timing for the intervention of malocclusions [1,2], which have been traditionally based on growth stages, as assessed by skeletal parameters [3][4][5][6]. Alternatively, dental calcification categorization systems have also been explored as a proxy tool to guide the orthodontic intervention, due to its prompt accessibility [7][8][9][10]. Different parameters using cervical vertebrae [5,6] and carpal bones [3,4], as well as teeth calcification stages [11,12] -as observed in lateral teleradiographs, hand-wrist and panoramic radiographs, respectively, compose a wide variety of available methods to identify the biological age.…”

Objective: Amongst other factors, the effectiveness of orthodontic treatment in children and adolescents depends on the identification of most appropriate intervention timing, which has been traditionally based on the identification of maturational stages. There is a wide variety of radiographic methods to identify these phases, either through skeletal parameters, or dental calcification. Considering that the reliability of any given assessment tool is required to enable its safe clinical use, and aiming an appropriate implementation of these parameters in future researches, this study was performed to assess the reproducibility of radiographic growth evaluation methods. Methods: Lateral teleradiographs, hand-wrist, and panoramic radiographs of sixty-eight orthodontic patients randomly selected from files of the Orthodontics Graduation Course (Guarulhos University, Guarulhos, SP, Brazil) were evaluated by two examiners to access both intra- and inter-examiner reproducibility of the assessment methods conceived by Baccetti et al.; Fishman; Greulich and Pyle; Nolla and Demirjian et al. Results: All methods analyzed showed satisfactory intra- and inter-examiner reliability. Among those that evaluated skeletal maturity, a relatively better performance was observed for Baccetti’s method. Fishman’s and Greulich’s parameters presented similar rates, as did Nolla’s and Demirjian’s. Conclusion: The assessment tools analyzed presented adequate reproducibility and might potentially be used as assessment tools to evaluate children and adolescent’s craniofacial growth. Further researches could evaluate the accuracy of radiographic dental calcification parameters for the identification of craniofacial growth stages.

“…The time of intervention in orthodontics is a key factor during diagnosis since the growth of patients has a huge impact on the treatment plan and outcomes ( 1 , 2 ). Despite chronological age can guide the treatment timing, there is a recognizable individual variation on development stages that might lead orthodontists to look to other methods to assess maturation and predict facial growth ( 3 , 4 ). Individual skeletal maturation is an exceptionally diverse variable as chronological age and skeletal age often do not match ( 5–7 ).…”

Summary Background The timing of growth is a key factor for correct orthodontic treatment planning. Cervical vertebrae maturation (CVM) is no exception, although the reported chronological ages vary in the literature. Objective We aimed to estimate the average chronological age for each Baccetti’s CVM staging. Search methods Search on MEDLINE-PubMed, Scopus, LILACS, Google Scholar, Cochrane Central Register of Controlled Trials (CENTRAL) was conducted until July 2021. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Selection criteria Observational or interventional studies reporting chronological age classified through Baccetti’s CVM method were included. Data collection and analysis Methodological quality was assessed, and pooled estimates were carried out through random-effects meta-analysis of single means. The impact of sex and continent were also investigated through subgroup analyses. Results Forty-one studies were included (9867 participants, 4151 men, and 5716 women). The average chronological age was 9.7 years old (95% confidence interval [CI]: 9.4 to 10.1) in CS1, 10.8 years old (95% CI: 10.5 to 11.1) in CS2, 12.0 years old (95% CI: 11.7 to 12.2) in CS3, 13.4 years old (95% CI: 13.2 to 13.6) in CS4, 14.7 years old (95% CI: 14.4 to 15.1) in CS5, and 15.8 years old (95% CI: 15.3 to 16.3) in CS6. A significant difference was found between the sexes in all CVM stages. We also found significant differences across continents. Conclusions For each CVM staging a chronological age range was successfully estimated. Girls presented an earlier skeletal maturation compared to boys. The skeletal maturation differs also according to continents, except for CMV stage 1, pointing to the need for personalized ranges according to each region.
