MANDIBULARY DENTAL ARCH FORM DIFFERENCES BETWEEN LEVEL FOUR POLYNOMIAL METHOD AND PENTAMORPHIC PATTERN FOR NORMAL OCCLUSION SAMPLE

Background: Menarche and skeletal maturation indices are physiological maturation indicators that can be used to establish the maturation stage of individual patient in orthodontic treatment, especially in orthodontic growth modification and orthognatic surgery. Purpose: The purpose of this study was to determine the relationship between menarche and the peak of skeletal maturation using hand-wrist and cernical vertebrae indexes. Methods: This was an observational diagnostic research with 220 female of Deutero-Malay Indonesian subjects aged 8-17 years from Dental Hospital Faculty of Dentistry Universitas Padjadjuran, and some privates orthodontic practice in Bandung. All subjects had hand-wrist radiograph and lateral cephalogram. Menarche data were collected through interview with the subjects and their parents. There were 89 subjects who already had menarche but only 84 of them remembered the month and year of their menarche. The stage of hand-wrist skeletal maturation was analyzed using Fishman method and cervical vertebrae maturation was analyzed using Baccetty et.al., method. Results: The result indicates that the menarche age of lndonesian Deutero¬-Malay subject were 12.47 ± 0.73 year. The youngest age of were 10.92 ± 0.0 year and the oldest were 13.83 ± 0.23 year. Conclusion: Menarche could he used as an indicator that the pubertal growth peak has been exceeded and to predict the end of the pubertal growth. This study showed that 0.49 years after MP3cap stage of hand-wrist skeletal maturation index and 0.69 years after CVMS2 stage of cervical vertebrae skeletal maturation index, the subject of Indonesian Deutero-Malay will have their menarche.
