BONE AGE AND CHRONOLOGICAL AGE FREE

Conclusion: Dental development is an independent system, that is regulated by different mechanisms than skeletal development and growth. The periodically malnourished cohorts of low SES Mayas and Ladinos are significantly delayed in dental maturation compared to the well-nourished low-middle and middle class Ladino children. In skeletal maturation, the middle SES cohort is significantly advanced compared to all other cohorts. All cohorts differ significantly in height. The distinction between cohorts differs according to each of the three measurements. Results: Dental age shows only a weak correlation with skeletal age (0.18) and height (0.2). The boys, aged between 7 and 12, derived from different social backgrounds (middle SES (N = 6529), low-middle SES (N = 736), low SES Ladino (N = 3653) and low SES Maya (N = 4587). Sample and Method: Dental, skeletal and height data from the 1970s to 1990s from Guatemalan boys were converted into standard deviation scores, using external references for each measurement. We further evaluate how the three different variables behave in cohorts from differing social backgrounds. We hypothesize that dental age correlates with body height and skeletal age. Objectives: We assess the interrelationship between dental eruption and other maturational markers.

Dental eruption is a potential, but highly debated, radiation free alternative. Yet, it relies on exposing children to x-radiation. Skeletal maturation is the standard measure. Stunting is a complex phenomenon and may be considered a synonym of social disadvantage and poor parental education.īackground: Biological age markers are a crucial indicator whether children are decelerated in growth tempo. The shortness of SEPE disadvantaged children was not associated with anthropometric and clinical signs of malnutrition, nor with delay in physical development. Maternal education interacted with height in affluent (r = 0.20, p < 0.01) and in underprivileged children (r = 0.20, p < 0.01). The correlation between height and state of nutrition (BMI_SDS, skinfold_SDS, MUAC_SDS) ranged between r = 0.69 (p < 0.01) and r = 0.43 (p < 0.01) in private school children, and between r = 0.07 (ns) and r = 0.32 (p < 0.01) in the underprivileged children. Underprivileged children are physically fitter than the wealthy. Clinical signs of under- or malnutrition were absent even in the most underprivileged children. The prevalence of stunting was between 8.5% and 46.8%. Subjective self-confidence was assessed by the MacArthur test. We investigated anthropometric data, clinical signs of malnutrition, physical fitness, parental education, and household equipment. We measured 723 children (5.83 to 13.83 years) Kupang, Indonesia three schools with different social background. In view of previous work on the lack of association between nutrition and child growth, we performed a study in urban schoolchildren. Socially, economically, politically and emotionally (SEPE) disadvantaged children are shorter than children from affluent background. To support our findings further a well-designed, controlled as well as longitudinal studies with a larger sample size is required. It is important to consider dental age and bone age as variables for diagnosing underweight children. The data supports the concept that dental age and bone age delay is a significant feature in underweight children. The correlation between chronological age, dental age and bone age were all positive in males. Bone age assessment was carried out using hand wrist radiograph following Bjork, Grave and Brown's method.ĭental age and Bone age was delayed compared to chronological age in both sexes. Dental age assessment was done using orthopantamogram following the method described by Demirjian. Chronological age was assessed by recording date of birth. Therefore, objective of this study was to determine and compare dental age, bone age and chronological age in underweight children.ġ00 underweight children between the age group of 18-14 years were selected. There are few studies, which showed the relationship between dental age, bone age and chronological age in underweight children. It is essential for a pediatric dentist to formulate treatment plan and it is a source of complementary information for pediatrician. The knowledge of bone age and dental age is of great importance for pediatrician and pediatric dentist.
