Altered expression of a number of genes has been correlated to biological ageing in humans. The biological age predicted from gene expression levels is known as transcriptomic age. This differs from chronological age which is measured as the time that an individual has lived since their date of birth. Transcriptomic age can be older or younger than an individual’s chronological age. At present,...

OBJECTIVES The objective of this study was to compare the long-term auditory performance and language skill depending on the age of cochlear implantation in the Korean population. We especially tried to separate the effect of maturation/development from that of the age at implantation. METHODS Eighty-six pre-lingual children with profound hearing loss who underwent a cochlear implantation bef...

Objective. To evaluate the difference between chronological and dental age, calculated by Willems and Cameriere methods, in various skeletal patterns according to Steiner's ANB Classification. Methods. This retrospective cross-sectional study comprised the sample of 776 participants aged between 7 and 15 years (368 males and 408 females). For each participant, panoramic images (OPT) and laterol...

introduction: the purpose of this study was to evaluate the relationship between the body mass index (bmi) and dental development. methods: the dental ages of 196 children were calculated according to demirjian’s method. the chronological age, weight, and height were recorded. dental development was defined as dental age minus chronological age. children were classified into three groups accord...

OBJECTIVE The purpose of this investigation was to evaluate the applicability of the methods proposed by Nolla and by Nicodemo and colleagues for assessing dental age and its correlation to chronological age. METHODS Panoramic radiographs of 360 patients from the city of Fortaleza (CE, Brazil) aged 7-15 years were used to assess the associations between dental and chronological age. Data were...

BACKGROUND Physical activity (PA) shows a marked decline during adolescence. Some studies have pointed to pubertal status or timing as possible PA determinants in this age group. Furthermore, it was supposed that the impact of pubertal changes on PA might be mediated by psychological variables like body dissatisfaction (BDS). METHODS The 11- to 17-year-old subsample of the German Health Inter...

Determining a child's chronological age and stage of maturation is particularly important in fields such as paediatrics, orthopaedics, and orthodontics, as well as in forensic and anthropological studies. Some systemic conditions can cause abnormal physiological maturation, and skeletal maturation is usually more delayed than dental maturation. The aim of this study was to determine dental age ...

This paper details a method for age determination of adults from single rooted teeth. The sample consisted of 100 Italian white Caucasian patients (46 men, 54 women) aged between 18 and 72 years. The single rooted maxillary right canine was utilized in this preliminary study. Pulp/root ration, tooth length, pulp/tooth length ratio, pulp/tooth area and pulp/root width ratios at three different l...
