Abstract

A morphometric analysis of changing proportions during mandibular development was undertaken in 30 human fetuses of both sexes (gestational age from 13 to 37 weeks). Reference points located on the mandible were, condylar process (Pel), coronoid process (Pco), gonion (Go), gnathion (Gn), superior symphyseal point (SSP), mental foramen (Fme), mandibular foramen (FMa) for measuring linear dimensions. The gonial angel, PcH-Gn-Pc',2 angel and Pcl-lm-Pco angels were measured. All linear dimensions were correlated with the gestational age. The mandibular body grew faster than the ramus in the 3rd trimester. All linear measurements were noted to be larger in male fetuses than in female fetuses. Gonial angel and Pcl-lm-Pco angels were not changed, while and Pcl1-Gn-Pcl2 was increased (P<0.05) in the fetal period. It observed that mandibular growth was allometric. The knowledge of the fetal mandibular growth is useful information for the anatomy, antropology, orthodontics and reconstructive surgery.

Özet

Mandibula gelişimi süresince değişikliklerin morfometrik analizi, her iki cinsiyetten gestasyonel yaşları 13-37 hafta arasında değişçn 30 adet insan fetusunda yapıldı. Lineer boyutların ölçümü için mandibula üzerinde lokalize olan referans noktaları; proc. condylaris (PcI), proc. coronoideus (Pco), gonion (Go), gnathion (Gn), symphysis üst noktası (SUN), for. mentale (FMe), for. mandibulae (FMa) olarak belirlendi. Gonial açı, Pcl1-Gn-Pcl2 açısı ve PcI-Im-Pco açıları ölçüldü. Bütün lineer boyutlar gestasyonel yaşla korelasyon gösteriyordu. Corpus mandibulae 3. trimester'de ramus mandibulae'den daha hızlı büyüyordu. Bütün lineer ölçümler erkek fetuslarda dişi fetuslardan uzundu. Fetal periyot boyunca gonial açı ve Pcl-lm-Pco açısı değişmiyor, Pcl1-Gn-Pcl2 açısı artıyordu (P<0.05). Mandibular büyümenin allometrik olduğu gözlendi. Fetal mandibular büyümenin bilinmesi anatomi, antropoloji, ortodonti ve rekonstriktif cerrahi açısından faydalıdır.
