THE RELATIONSHIP BETWEEN MENARCHE AND SKELETAL MATURATION STAGE OF DEUTERO MALAY INDONESIAN SUBJECT

Menarche and skeletal maturation indexes are physiological maturation indicators that can be used to establish the maturation stage of individual patient in orthodontic treatment. Especially in orthodontic growth modification andorthognatic surgery.The purpose of study is to determine the relationship between menarche and the peak of skeletal maturation using hand-wrist and cervical vertebrae indexes. This study is an observational diagnostic research with 220 female of Deutero-Malay Indonesian subjects aged 8-17 years.from RSGM Faculty of Dentistryof PadjadjaranUniversity, and some privates orthodontic practice in Bandung.All the subjects had hand-wrist radiograph. and lateral cephalogramMenarche data were collected through interview with parents and the subject. There were 89 subjects who already had their menarche but only 84 of them remembered the month and year of their menarche. The stage of hand-wrist skeletal maturation analized using Fishman method and cervical vertebrae maturation was analized using Baccetty et.al., method.The result indicates that the menarche age of Indonesian 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. The peak of hand-wrist skeletal maturation (MP3cap) were 11, ±0,56 years and the cervical vertebrae maturation CVMS 2 were 10,61 ± 0,98 years and CVMS3 were 12,58 ± 1,28 years. 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.
