Abstract

The prevalences of dental caries and periodontal diseases are very high in Korea. Most efforts have been focused on development of the prevention and early treatment of dental caries and periodontal diseases. The purpose of this study was to obtain the baseline data on the prediction of craniofacial bone growth and development. The author obtained lateral cephalograms and hand-wrists radiographs, standing and sitting height, weight, and chronologic age from a sample of 340 six-year-olds Korean girls. 16 skeletal linear measurements representative of craniofacial patterns were selected to be analyzed in this study. The hand-wrist radiographs were scored by the Tanner-Whitehouse TW2 method of skeletal maturity assessment. A correlation analysis was used to identify correlations between skeletal maturity score of hand-wrist, and standing and sitting height, weight, chronologic age and 16 skeletal linear measurements in facial dimensions of lateral cephalograms.
The obtained findings were as follows:
1. Standing and sitting height, weight and chronologic age were significantly
related to the bone age of hand-wrist.
2. The highest percentages of the developmental stage assigned to each hand-wrist among 6 year-old girls were as follows:
G stage of radius was 99.4%, E stage of the third middle carpal bone was 89.1%, E stage of the fifth middle carpal bone was 90.8%, E stage of the first proximal phalange was 95.3%, E stage of the third proximal phalange was 97.0%, E stage of the third middle phalange was 99.1%, E stage of the fifth middle phalange was 87.0%, E stage of the fifth distal phalange was 88.2%, F stage of capitate was 80.6%.
3. The lengths of S-Gn, N-Go, N-B, N-Pog and A-B were significantly related to the the bone age of hand-wrist.
