“…Also, the recognition of reference points was difficult. However, according to Plascencia et al ( 39 ), the intra- and interobserver agreement provided reliable results in the radiographic assessment of different stages of root development using the Cvek classification. As previously mentioned, the two-dimensional dentin wall thickness data from the intraoral radiographs could be used for 3D modelling of MCI.…”

Objective The aim of this study was to determine the average dentin wall thickness (DWT) of the maxillary central incisor (MCI) required for performing finite element analysis (FEA) models of root development. Material and methods A total of 137 intraoral periapical radiographs of MCI in children aged 7 to 11 years were examined and then classified into 5 groups according to root development stages, which included 1/2 of root development (S1), 3/4 of root development (S2), more than 3/4 of root development (S3), complete development with wide-open apex (S4) and complete development with closed apex (S5). DWT was measured at three reference (horizontal) lines: at a distance of 1 mm from the apex (M), 4 mm from the apex (L) and at the cervical line (K). The distal dentin wall thickness (M1, L1, and K1), the pulp thickness (M2, L2, and K2), the mesial dentin wall thickness (M3, L3, and K3), and the apex thickness (N) were measured using the diagnostic software Soredex Scanora 5.1.2.4. Statistical analysis compared the values of the parameters K, L, and M between developmental stages (multivariate ANOVA) and the linear correlations between the parameters (Pearson's correlation analysis). All analyses were performed at significance level α = 0.05. Results There were statistically significant differences between the developmental stages for parameters L and M, while no significant differences were found for parameter K. Most of the correlations between the parameters were statistically significant, with the values of the Pearson correlation coefficient R > 0.6 considered practically significant. All parameters on the same reference line for distal and mesial dentin wall thickness and for pulp thickness correlated well with each other (R = 0.46 – 0.68), but there was no statistically significant correlation with total root thickness on the same reference line (parameters K, L, or M), except for parameter K3 (R = 0.42). Conclusion Despite the limitations of this study, the mean values of the selected parameters for the 5 groups of developmental stages of the maxillary central incisor could be used to model dentin wall thickness using finite element analysis.

“…U ovom makroskopskom pristupu metode konačnih elemenata sva mjerenja obavila je jedna osoba kako bi se pogreške svele na minimum. Uzimajući u obzir 137 radiografija različitih pacijenata i njihovu individualnu anatomiju, nije bilo lako identificirati isti kut na snimkama i prepoznavanje referentnih točaka, ali prema Plascenciji i suradnicima (39) podudarnost unutar promatrača i između njih dala je pouzdane rezultate u radiografskoj procjeni različitih faza razvoja korijena s pomoću Cvekove klasifikacije. Kao što je ranije spomenuto, dvodimenzionalni podatci o debljini stijenke dentina iz intraoralnih radiografija mogu se koristiti za 3D modeliranje MSS-a, no bolja obilježja postigla bi se pregledom 137 CBCT-a, što je kod djece etički vrlo upitno.…”
