Abstract

Latar belakang: Intervensi awal seperti pengekstrakan molar kekal pertama (FPMs) yang mempynyai prognosis yang tidak baik pada masa optimal dan rawatan dengan alatan yang berfungsi adalah penting dalam pengurusan ortodontik. Sasaran: Untuk menentukan anggaran umur ideal untuk pengekstrakan prognosis tidak baik molar kekal dan puncak pertumbuhan mandibular menggunakan OPG dalam kalangan populasi Melayu. Kajian ini juga membuat perbandingan umur kronologikal pada tahap perkembangan krip pada setiap tiga molar di antara jantina, rahang atas dan bawah kanan dan kiri pada setiap rahang. Background: Early intervention such as extraction of poor prognosis first permanent molars (FPMs) during the optimal time and treatment with functional appliances are essential in orthodontic management. Aim: To determine the ideal age range for extraction of poor prognosis FPMs and peak mandibular growth using orthopantomogram radiographs (OPG) in Malay population. This study also compared the chronological age of crypt stage developmental of each third molar between genders, upper and lower jaw, right and left in each jaw.
