“…A recent Korean study showed that the plateau of the pubertal growth spurt was at 14 years in girls and at 16 in boys 25 , 32 . The maximal growth velocity has tended to be faster 25 ; therefore, 14 would be a better cutoff for Korean children to distinguish ages in volumetric growth from maturation periods. Age under 20 could suggest late physical maturation and end of adolescence.…”

“…Patients were divided into three age categories: (1) age under 14 years, (2) age ≥ 14 years and < 20 years, and (3) ≥ 20 years. Age 14 is considered to be the age of the last growth spurt in Korean children 25 , and age 20 is the border between adolescence and adulthood in the WHO classification 26 . Patient distribution according to age categories is described in Table 2 .…”

The aim of this study is to identifying post treatment recurrence rates in pneumothorax patients under 35 and without any comorbidities according to the treatment types, gender, and age categories based on nationwide population data. Clinical information of pneumothorax patients was extracted from the Korean National Health Insurance Service (NHIS) database between January 2002 and December 2020. Enrolled patients were categorized into two groups; (1) Group I, those who underwent conservative management including pain relief, oxygen therapy, and closed thoracostomy, and (2) Group II, surgical intervention. Recurrence rates were compared according to age, gender, and type of treatment. Surgical intervention was performed in 25.6% patients as first treatment. The overall recurrence rate was 20.3%. Male patients showed a higher 5-year recurrence rate than female (20.8% vs. 10.9%, p < 0.001). Those with conservative management showed lower 5-year recurrence rates than those with surgical treatment (7.9% vs. 23.7%, p < 0.001). The 5-year recurrence rates of patients aged 14≤, and < 20 was higher than other age groups (29.2% vs. 4.5 and 11.9%, p < 0.001). Surgical intervention, male gender and aged under 20 showed association with higher recurrence rates.

“…Several studies have reported on the stage of peak height velocity in SMI and MP3 classification. Hägg and Taranger [9] considered SMI stage 6 as the maximum growth period and according to studies on Koreans, Kim et al [24] reported that males are most commonly found in SMI stages 5 -7 and females in stages 6 -7, whereas Lee and Mah [25] reported that males are found in SMI stages 4 -5 and the MP3 FG -G stage and females in SMI stages 3 -4 and the MP3 F -FG stage. To improve the accuracy of growth prediction, it is recommended that additional morphological, biological, and genetic indicators be evaluated [26,27].…”

The aim of this study was to assess the correlation between serum levels of insulinlike growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3), and hand-wrist radiographs using a skeletal maturity indicator (SMI) and the middle phalanx of the third finger (MP3). Hand-wrist radiographs and blood samples from 205 patients aged 7 - 17 years were retrospectively analyzed by two dentists using the SMI stages, MP3 stages, and serum IGF-1 and IGFBP-3 levels. Serum IGF-1 levels were highest at the SMI 6 - 8 and MP3 - G stage and lowest at the SMI 1 - 3 and MP3 - F stage (p < 0.0001). Serum IGFBP-3 levels were highest at the SMI 9 - 10 and MP3 - I stage and lowest at the SMI 1 - 3 and MP3 - FG stage (p = 0.010, 0.030). As a result of Pearson correlation analysis, a relatively high correlation was found between skeletal maturity using the SMI and MP3 stages and serum IGF-1 levels (r = 0.698, 0.622, p < 0.0001). According to the results of this study, serum IGF-1 levels can be used as an auxiliary measure to evaluate the skeletal maturity of children and adolescents in dentistry. The range from the mean serum IGF-1 level of 472 µg/L in SMI 6 stage to the mean IGF-1 level of 510.63 µg/L in MP3 G stage could be considered as the peak height velocity in clinical practice.

“…This study had a limitation related to the lack of interpretation on SMI 7 -9 stages whether corresponding to the mid- Although the hand -wrist radiograph is the most common method to evaluate the skeletal development due to its objective and simple interpretation, high reproducibility, and minimal radiation exposure, it is not yet described as an absolute "gold standard" for the skeletal maturity [28]. As a result, if more studies on prediction of midpalatal suture maturation with various other methods to assess the skeletal maturity will be proceeded, the midpalatal suture maturation can be more accurately determined.…”

The aim of this retrospective study was to evaluate the correlation between the midpalatal suture maturation and skeletal maturation in growing children aged 7 - 15 years and predict the maturational stages of the midpalatal suture corresponding to skeletal maturity assessed by the skeletal maturation indicators (SMI) and middle phalanx of the third finger (MP3) stages.The group of this retrospective study was consisted of randomly selected 132 male and 135 female in age from 7 - 15 years. The maturation of the midpalatal suture was evaluated by using images from cone-beam computed tomography (CBCT) while the skeletal age was assessed by hand-wrist radiography. CBCT images and hand-wrist radiographs used in this study were obtained from all subjects for orthodontic diagnosis before orthodontic treatment.The maturational stages of the midpalatal suture showed strong correlations with both SMI and MP3 stages. The correlation between the midpalatal suture maturation and SMI (Spearman’s correlation coefficient, ϒS = 0.905, p < 0.05) was slightly greater than that of MP3 stages (ϒS = 0.830, p < 0.05). There was a positive significant correlation between the midpalatal suture maturation and chronological age (ϒS = 0.868,p < 0.05).CBCT for evaluation of the midpalatal suture maturational stages may be unnecessary in every pediatric patients because SMI and MP3 stages were both replaceable useful methods for assessing maturation of the midpalatal suture before orthopedic treatment. In this retrospective study, the diagnostic reliability of the SMI method for estimating midpalatal suture maturation showed better reliability than the MP3 method.
