Objectives: To compare Demirjian Dental scoring method with Greulich-Pyle (GP) Skeletal method of age estimation in pubertal children. Materials and Methods: Sample of the study included 267 male healthy subjects of 11-16 years of age group.. Demirjian Scoring system was utilized to evaluate the orthopantomograms to assess their Dental age and the Hand-Wrist radiographs were analyzed to calculate the skeletal age by utilizing GP atlas. Chronological age was obtained from the date of birth of the subject .Both methods were compared with one another and with the chronological age. It was a cross-sectional study and only healthy male subjects without any clinical abnormalities were included in the study. Results: A total of 267 male subjects of 11-16 years of age group were assessed by Demirjian and Greulich Pyle Methods. Both were compared with Chronological Age. Data obtained was statistically analyzed and the Student “t” test was applied in the study population. The mean difference between Chronolgical age and dental age was 0.69years and that of chronological age and skeletal age was 0.87 years. It was observed from dental age assessment that it does not differ much from the skeletal age. Conclusion: It was concluded that Demirjian method of Age Estimation is more precise than Greulich Pyle method of Age Estimation. Furthermore both methods can be used selectively in Medicolegal cases to access bone age which can be easily correlated to chronological age.

The Demirjian methods to determine dental age are based on analysis of orthopantograms. The dental age estimation is based on establishing the tooth development stages. The purpose of this study was to assess the accuracy of estimation of dental age by Demirjian in the use of all of his four methods. 505 Czech healthy boys and girls aged 3 to 18 years were examined radiographically at the Department of Stomatology, Second Faculty of Medicine, Charles University in Prague. It was mentioned the factors of underlying diseases influence the accuracy of the dental age estimation. For statistical evaluation, descriptive statistics was used to compare deviations of the mean values of chronological and dental age in each age group. The resulting difference between dental age and chronological age is not significant in both genders only when using both Demirjian 7-teeth methods of 1973 and 1976. Therefore these may be most appropriately used for forensic age estimation. There are shown standard deviation differences in different countries. Demirjian’s original 7-teeth method from 1973 and Demirjian’s revised 4-teeth method from 1976 appear to be the best methods for calculating the dental age of healthy Czech children of both genders.

Objective: To assess dental age and deviations of dental from chronological age according to the Willems and Cameriere methods (European formula) in patients with cleft lip and/or cleft palate (CL/P) and compare it with control group. Design: Retrospective cross-sectional study. Setting: Clinic of Orthodontics. Participants: Sixty-nine patients with CL/P between 6 and 15 years of age (55 with unilateral and 14 with bilateral CL/P) with 148 panoramic radiographs. The same number of radiographs was examined in the age-matched control group. Main Outcome Measures: Estimation and comparison of dental age and differences of dental from chronological age in relation to the type of cleft, sex, and age in the group of patients with and without CL/P according to Willems and Cameriere method. Results: No significant intersex and intergroup differences were found in deviations of dental from chronological age according to Cameriere method ( P > .05). Significant difference in deviation of dental from chronological age was found between the patients with and without CL/P according to Willems method ( P < .001). Conclusion: Cameriere European formula for dental age estimation, which is not influenced by sex and tooth morphology, showed similar dental development of children with and without CL/P. However, Willems method detected that deviation of dental from chronological age significantly differed between children with and without clefts.

ABSTRACT Objectives: To evaluate the accuracy of Demirjian method in estimating the chronological age of male and female Jordanian children and to establish a new dental age curve if the Demirjian method was not found to be accurate. Methods: Orthopantomograms (OPTs) of 1374 Caucasian Jordanian children (684 females and 690 males) aged 4 to16 years were selected and the dental age was determined by Demirjian method. The chronological ages of the children were obtained by subtracting their birthdates from the date of taking the radiograph. The OPTs were obtained from Archives of Dental Teaching Clinics /XXX and other private orthodontic practices in Irbid and Amman. Results: Demirjian method overestimated chronological age in female and male subjects aged 4 to 8 years. Afterwards, the method underestimated chronological age in females aged 9-11 years and 14-16 years. In male subjects, chronological age was underestimated in subjects aged 9-12 years and 15-16 years. New the dental age curves for Jordanian females and males were constructed. The constants for the quadratic model for the new curves were (b0=-25.341, b1=17.557, b2=-0.623) for females and (b0=-29.809, b1=17.396, b2=-0.595) for males. Conclusion: Demirjian method overestimated the chronological age of Jordanians below the age of 8 years and underestimated the age of Jordanians above 8 years. A new DA standard for Jordanian children was developed and tested for accuracy.

Background: Growing individuals not only differ in the timing of the maturational events, but also in the sequence of these events. Age is one of the essential factors, which play an important role in every aspect of life like in clinical, medico-legal, forensic and anthropological applications and in planning treatment of   orthodontic and pedodontic patients. The aim of the study was to determine dental age from                       orthopantomogram using Demirjian’s method and Nolla’s method and to evaluate the interrelationship     between chronological and dental age according to both these methods. Materials and Methods: A cross sectional study was carried out in 177 orthopantomograms of the patient aged between 5 to 15 years. Dental age estimation was done with Demirjian’s and Nolla’s method. Results: The mean chronological age 10.14 + 3.16 compared with the mean Demirjian age 9.58 + 3.39 was statistically non significant p > 0.05 whereas comparision with mean Nolla age 7.88+ 1.56 was significant statistically. Conclusions: Both methods showed delayed dental age compared to chronological age. Demirjian’s method was more  applicable to    assess the dental age in Nepalese children compared to Nolla’s method.Keywords: chronological age; dental age; Demirjian’s method; Nolla’s method.

Background: In recent years, age estimation in forensic medicine has become so important. Teeth are used to estimate age as valuable indicators. Objectives: This study aimed to compare Cameriere and Demirjian methods in estimating chronological age (Age) in an Iranian population and to develop a modified Cameriere method. Methods: In this cross-sectional study, we investigated a total of 486 panoramic radiographs of individuals aged 5 - 15 years adopted from two craniofacial radiology centers in Babol, northern Iran, in 2019. The dental age of subjects was assessed by Demirjian (DAge) and Cameriere (CAge) methods and compared with their chronological age. Also, a formula was designed based on the Cameriere method for our studied population, and the results of the original and modified Cameriere (MCAge) methods were compared. Results: The mean ± SD of Age (10.38 ± 2.30) had a significant difference with DAge (10.67 ± 2.33) and CAge (9.77 ± 2.01) (P < 0.001). The modified Cameriere formula was more accurate than Cameriere one, and MCAge was 10.38 ± 2.12, indicating no significant difference with Age (P = 0.993). Conclusions: According to our results, both Demirjian and Cameriere methods were not reliable for age estimation in the Iranian population. However, the modified Cameriere formula had a very high accuracy in estimating the age of the studied population.

Schour-Massler and Demirjian are methods used to estimate chronological age in dental radiographs by looking at the development of permanent teeth and the maturity of the dental age. Chronological age is based on date of birth. Dental age is the age based on the maturity of the teeth. Both of these methods have been widely used in previous studies, but have never been compared. The purpose of this study was to determine whether there are differences in age estimation using the Schour-Massler and Demirjian methods. This study was an observational analytic study with a cross sectional design. The research sample was 46 patients who came to USU General Hospital at the age of 10-16 years. This research was consist at the Radiology Unit of the Faculty of Dentistry, University of North Sumatra. The results of this study indicate the p value of the Wilcoxon test results with the p value for Schour-Massler p=0.090 > 0.05 and Demirjian p=1,000. Both p values> 0.05, there is no significant difference in assessing the estimated age using both methods, so Ha is accepted. In conclusion, the Schour-Massler and Demirjian methods provide estimates of age that are close to actual age, so there is no significant difference between the two methods.

Abstract BackgroundMany treatment decisions in children’s Orthopaedics are based on age. This study determined whether a discrepancy between chronological age (CA) and skeletal age (SA) is dependent on BMI and if overweight or obese children would have an advanced SA.Materials and Methods120 children between ages 8-17 with an adequate hand radiograph and a correlating BMI were enrolled by retrospective chart review. Stratification based on age, sex, ethnicity, and BMI percentile was performed. For each age group, 6 males and 6 females were selected with 50% of each group having an elevated BMI. Two blinded physicians independently evaluated hand radiographs and recorded the SA. Statistical analyses evaluated inter-rater reliability and any discrepancy between groups.ResultsThe final statistical analysis included 96 children. The Intraclass Correlation Coefficient for SA determined by the two reviewers was excellent at 0.95. A difference of 13 months was found between CA and SA in the elevated BMI cohort versus the non-elevated BMI cohort, (p<0.001). No significant difference was seen between CA and SA for the non-elevated cohort (p=0.72), while matching for age and sex. ConclusionChronological age and skeletal age are not always equivalent especially in pediatric patients who are overweight or obese.

ABSTRACT Aim The aim of this study was to evaluate the maturity levels of the individual by comparing the correlation between dental, skeletal and the chronological ages. Materials and methods Intraoral periapical radiographs of the complete right side of the dentition and posteroanterior radiographs of the hand and wrist were obtained from 260 subjects, ranged from 3 to 15 years of age. Evaluation of handwrist roentgenograms for skeletal age and intraoral roentgenograms for dental age was done. Results The findings of present study indicated that participated children were skeletally and dentally, retarded in maturation as compared with the standards except at 3 and 6 years of age. The girls were found to be skeletally more advanced than boys at all ages except 7 and 10 years of age. The dental maturity is more for girls than that of boys. Conclusion No significant correlation was found among skeletal age, dental age and chronological age. Dental age and skeletal age was found to be correlated at 6, 10 and 11 years in boys and 6 and 9 years of age in girls. Clinical significance The results of this study could enhance the diagnosis and treatment planning in orthodontics and other dental disciplines.

BACKGROUND Stunting is a major public health issue in most of developing countries. Although, its worldwide prevalence is decreasing slowly but the number of stunted children is still rising in Pakistan. Stunting is highly associated with several long-term consequences, including higher rate of mortality and morbidity, deficient cognitive growth, school performance, learning capacity, work capacity and work productivity. To prevent stunting, we proposed Stunting Diagnostic and Education app. This app includes detailed knowledge of stunting and it’s all forms, symptoms, causes, video tutorials and guidelines by the Pediatricians and Nutritionists. OBJECTIVE The aim and objective of this study is to assess the prevalence of stunting in school-going children in Multan District of Punjab Pakistan and to analyze the risk factors associated with stunting in children under and over 5 age. This study presents Stunting Diagnostic and Education app to prevent the stunting in children under 5 age and children over 5 age (where required). METHODS A cross-sectional study has been conducted in schools of Multan District, Pakistan for the period of January 2019 to June 2019. Sample data of 1420 children, aged 4 to 18 years using three age groups, were analyzed by using SPSS version 21.0 to assess the prevalence of stunting and to analyze the main factors associated with it. Chi square test was applied in comparison with rural and urban participants and p-value <0.05 was considered as significant. This study includes distribution of sociodemographic characteristics, parental education, working status of mothers, dietary patterns of school going children and prevalence of stunting in school going children. After getting study results, Stunting Diagnostic and Education app was developed according to the instructions of child experts and nutritionists. RESULTS 354 (24.93%) participants were stunted out of 1420, 11.9 % children were obese and 63.17% children were normal. Out of 354 stunted children, higher ratio of stunting was found in the age group of 8-11 years children with 51.98 percentage. 37.85% stunted children were found in the age group of 4-7 years and 10.17% stunting was found in the age group of 12-18 years children. It was observed in the study that male children were highly stunted than female with 57.91 % and 42.09% respectively. Children living in rural areas were more stunted affected as compared to the children living in urban society with percentage 58.76 and 41.24 respectively. CONCLUSIONS Our study concluded that 24.93% children were stunted, out of which, age group of 8-11 years children were highly stunted. The study showed that the literacy of mother or caregiver had high impact on children’s health. Therefore, Stunting Diagnostic and Education app was developed to educate mothers to prevent stunting.
