Objectives: To investigate the relationship between cervical vertebrae maturation and mandibular second molar calcification stages.Study design: The study was designed as a retrospective, descriptive and crosssectional research project. Pre-treatment lateral cephalograms and panoramic radiographs of 99 males and 110 females in the age range of 7 to 18 years 7 months were evaluated with Demirjian Index (DI) and cervical vertebrae maturation indicators (CVMI) of Hassel and Farman. A null hypothesis was proposed that there is no relation between CVMI and DI. Results: A highly significant association (Pearson's contingency coefficient 0.713 for males and 0.863 for females) was found between DI and CVMI. In males, the DI stage E corresponded to stage 2 of CVMI (pre–peak of pubertal growth spurt) and DI stages F and G corresponded to stages 3 and 4 of CVMI (peak of pubertal growth spurt). DI stage H was associated with stages 5 and 6 of CVMI (end of pubertal growth spurt). In females, the DI stages C, D corresponded to CVMI stages 1, 2; DI stages E, F with CVMI stages 3, 4; DI stages G, H with CVMI stages 5, 6. Conclusion: Mandibular second molar calcification stages can be used as indicators for assessment of skeletal maturity.

Objective: To investigate whether the craniofacial vertical and sagittal jaw relationship in patients with cleft lip and palate (CLP) differed from that of age-matched noncleft controls, before and after the pubertal growth spurt. Design: Retrospective observational study. Patients: The study group comprised 126 patients with CLP, subdivided according to gender and cleft type, and the control group comprised 53 age-matched skeletal class I patients. Methods: Angular and linear measurements were taken from prepubertal and postpubertal lateral cephalograms of all patients. Results: In patients with cleft lip and palate, the maxillary retrognathism became more remarkable with increasing age; whereas, the retrognathic position of the mandible became less pronounced as compared with controls. Reduced posterior midfacial height, a common prepubertal finding in patients with cleft lip and palate, was significant in postpubertal girls and young women with unilateral cleft lip and palate (p  =  .002). The total anterior facial height in male patients with bilateral cleft lip and palate was larger than in control patients (p  =  .002) after the pubertal growth spurt due to an increased anterior midfacial height. In male patients with unilateral cleft lip and palate, this finding was due to an increased anterior lower facial height (p < .001). Conclusions: Patients with cleft lip and palate treated according to a standardized treatment concept had adequate craniofacial jaw relationships after puberty. Despite a measured skeletal class I in both male and female patients with cleft lip and palate regardless of cleft type, there was a slight tendency toward a skeletal class III. Findings were similar for all groups of cleft lip and palate patients irrespective of the type of orthodontic treatment performed.

INTRODUCTION: This study was conducted with the aim of adapting the methods developed by Martins and Sakima to assess skeletal maturation by cervical vertebrae in the pubertal growth spurt (PGS) curve. It also aimed to test the reliability and agreement between those methods and the method of hand and wrist radiograph when compared two by two and all together. METHODS: The sample comprised 72 radiographs, with 36 lateral radiographs of the head and 36 hand-wrist radiographs of 36 subjects with Down's syndrome (DS), 13 female and 23 male, aged between 8 years and 6 months and 18 years and 7 months, with an average age of 13 years and 10 months. RESULTS AND CONCLUSIONS: Results revealed that adapting the methods developed by Martins and Sakima to assess skeletal maturation by cervical vertebrae in the curve of PGS is practical and useful in determining the stage of growth and development of individuals. The stages of maturation evaluated by cervical vertebrae and ossification centers observed in radiographs of the hand and wrist were considered reliable, with excellent level of agreement between the methods by Hassel and Farman as well as Baccetti, Franchi and McNamara Jr and Martins and Sakima. Additionally, results revealed an agreement that ranged between reasonable to good for the three methods used to assess the skeletal maturation, showing statistical significance.

ABSTRACT Objectives: To investigate the time and pattern of fusion of the spheno-occipital synchondrosis in patients with skeletal Class I and Class III malocclusion using cone-beam computed tomography (CBCT). Materials and Methods: A total of 262 CBCT images were collected: 140 skeletal Class I (0° &lt; ANB &lt; 4°; 71 males, 69 females) and 122 skeletal Class III (ANB ≤ 0°; 61 males and 61 females). The fusion stages were identified using CBCT images of a six-stage system defined by the appearance of osseous cores and ossifying vestige in the synchondrosis. The age distributions of each stage and the pattern of fusion were evaluated. Results: The stages of fusion progressed with increasing age (P &lt; .05, r = .824), and the age distributions in the female groups were generally 1 to 3 years younger than those in the male groups. However, no significant differences were observed between the skeletal Class I and Class III groups regarding the time of ossification of the synchondrosis. The osseous cores appeared most frequently in the supero-center part, followed by the mid-center part of the synchondrosis. Conclusions: The time and pattern of fusion of the spheno-occipital synchondrosis are not apparently different between patients with Class I malocclusion and those with Class III malocclusion. The osseous cores appear frequently in the supero-center and mid-center of the synchondrosis with various patterns before the end of the pubertal growth spurt period.

Abstract Objectives The aim of the study is to assess the skeletal age at the onset and end of the pubertal growth spurt and determine its duration in four growth type groups: (1) normodivergent skeletal Class I (I N), (2) normodivergent skeletal Class III (III N), (3) high-angle skeletal Class III (III H) and (4) high-angle skeletal Class I (I H). Materials and methods Two hundred thirteen subjects were selected from 2163 examined files. The cervical vertebral maturation stage was recorded by means of Baccetti’s method. The sagittal and vertical skeletal relations were evaluated according to Steiner analysis with Kaminek’s modification. The duration of the pubertal growth spurt was calculated from the difference between the means of the chronological age related to CS3 and CS4 maturation stages. Results The shortest lasting pubertal growth spurt was observed in group I N (1.1), followed by group III N (1.6). Major differences between arithmetic means CS4-CS3 were seen in groups I H and III H (2.3 and 2.7, respectively). Conclusions The following tendency was observed in the duration of the pubertal growth spurt: I N < III N < I H < III H. This tendency has statistical significance only in high-angle patients in comparison with normodivergent skeletal Class I. Clinical relevance Knowledge on the longer pubertal growth spurt in high-angle patients compared to patients with normal anteroposterior and vertical relationships can be useful in the selection of an appropriate therapeutic method and a treatment time.

Estrogen Production

Whether prepubertal estrogen production impacts on the timing of puberty is not clear. We aimed to investigate prepubertal 24-h estrogen excretion levels and their association with early and late pubertal markers. Daily urinary excretion rates of estrogens of 132 healthy children, who provided 24-h urine samples 1 and 2 yr before the start of the pubertal growth spurt [age at takeoff (ATO)], were quantified by stable isotope dilution/GC-MS. E-sum3 (estrone + estradiol + estriol) was used as a marker for potentially bioactive estrogen metabolites and E-sum5 (E-sum3 + 16-epiestriol + 16-ketoestradiol) for total estrogen production. Pubertal outcomes were ATO, age at peak height velocity (APHV), duration of pubertal growth acceleration (APHV-ATO), age at Tanner stage 2 for pubic hair (PH2), genital (G2, boys) and breast (B2, girls) development, and age at menarche. Prepubertal urinary estrogen excretions (E-sum3 and E-sum5) were not associated with ATO, APHV, and age at PH2 but with duration of pubertal growth acceleration ( P < 0.01) in both sexes. Girls with higher E-sum3 reached B2 0.9 yr ( P = 0.04) and menarche 0.3 yr earlier ( P = 0.04) than girls with lower E-sum3. E-sum3 was not associated with age at G2 in boys ( P = 0.6). For most pubertal variables, the associations with E-sum3 were stronger than with E-sum5. In conclusion, prepubertal estrogens may not be critical for the onset of the pubertal growth spurt but are correlated with its duration in both boys and girls. Prepubertal estrogen levels may already predict the timing of girls' menstruation and breast development but do not appear to affect sexual maturation in boys.

Late Maturer

From their observations in a boy with hypophosphatemic rickets Chan and Bartter1 conclude that administration of 1α,25-dihydroxyvitamin D3 (1,25-(OH)2D3) is the treatment of choice for this disease. Since this point of view is not shared by everybody, it demands careful scrutiny. The conclusion rests on the increased growth velocity, the radiologic healing of the rachitic lesions, and the increase in serum phosphorus which occurred when treatment was changed from vitamin D2 to 1,25-(OH)2D3. From the growth curve of this boy it appears that the increase in growth velocity could represent the pubertal growth spurt in a late maturer.
