Background:
The aim of this study was to determine the correlation between the coronal
movement of the permanent tooth germ (PTG) and apical foramen (AF), and to
determine whether the crown apex of PTG was a determining point regarding the
canal working length in the primary molar teeth.

Methods:
115 root canals of 30 primary molar teeth were divided into 3 groups according
to the position of the PTG (Group 1: PTG was below the roots of primary molar,
Group 2: PTG at the apical third of the roots of primary molar, Group 3: PTG at
the middle third of the roots of primary molar) by using cone-beam computed
tomography images. For each groups, correlation between coronal movement of the
PTG and AF was investigated by using reference points of root apex of primary
tooth, AF and crown apex of the PTG.

Results: In
Group 2, where the PTG was located at the apical third of the roots of primary
tooth, the correlation was found between the coronal movement of the PTG and AF.
However, this correlation was not found in Group 1 and 3, where the PTG was at
below the roots of primary molar and middle third, respectively.

Conclusion: It
was concluded that the crown apex of the PTG could be used as a reference point
in determining the canal working lenght in the case where the PTG was located
in the apical third.

DAİMİ DİŞ JERMİNİN KORONAL HAREKETİ İLE SÜT MOLAR DİŞLERİN APİKAL AÇIKLIĞININ YER DEĞİŞTİRMESİ ARASINDAKİ KORELASYONUN DEĞERLENDİRİLMESİ

Amaç: Bu
çalışmanın amacı, daimi diş jerminin
koronale sürme hareketi ile süt dişi apikal açıklığının koronal yöndeki yer
değiştirmesi arasındaki korelasyonun belirlenmesi ve daimi diş jermi kron
apeksinin, süt molar dişlerde kanal çalışma boyu açısından belirleyici bir
referans noktası olup olmayacağının araştırılmasıdır.

Gereç ve Yöntemler: Konik ışınlı bilgisayarlı tomografi görüntüleri
kullanılarak, 30 adet alt süt molar dişe ait 115 kök kanalı, daimi diş jerminin
konumuna göre 3 gruba ayrılmıştır (Grup 1: Daimi diş jermi süt dişi köklerinin
altında, Grup 2: köklerin apikal üçlüsünde, Grup 3: köklerin orta üçlüsünde).
Her 3 grup için, daimi diş jerminin koronale sürme hareketi ile apikal
açıklığın koronale yer değiştirmesi arasındaki korelasyon; süt dişi kök apeksi,
apikal açıklık ve daimi diş jerminin kron apeksi referans noktaları kullanılarak
araştırılmıştır.

Bulgular:
Daimi diş jerminin süt dişi köklerinin apikal üçlüsünde konumlandığı Grup 2’de diş
jermi ile apikal açıklığın koronale yer değiştirmesinde korelasyon tespit
edildiği (p<0,017), ancak daimi diş jerminin süt dişi köklerinin altında
ve orta üçlüsünde bulunduğu Grup 1 ve 3’te bu korelasyonun sağlanmadığı bulgulanmıştır.

Sonuç: Daimi diş
jerminin, süt dişi köklerinin apikal üçlüsünde bulunduğu durumda, daimi diş
jermi kron apeksinin kanal çalışma boyu belirlenmesinde referans noktası olarak
kullanılabileceği sonucuna ulaşılmıştır.
