GÝRÝÞ ve AMAÇ: Bu çalýþmanýn amacý konik ýþýnlý bilgisayarlý tomografi (KIBT) kesitlerinde sürmesi tamamlanmamýþ diþlerdeki gubernakular kanal (GK) varlýðýný tespit etmek ve diþlerin erüpsiyon süreci ile GK arasýndaki baðlantýyý ortaya koymaktýr.
YÖNTEM ve GEREÇLER: 105 bireyden, sürmesi gecikmiþ-gömülü kalmýþ veya normal erüpsiyon dönemindeki 250 diþ incelenmiþtir. Maksilla ve mandibuladaki tüm sürmemiþ diþler çalýþmaya dahil edilmiþtir. Ýncelenen diþler GK varlýðý bakýmýndan var-yok olarak sýnýflandýrýlmýþtýr. Ýncelenen diþlerin sürme engeli olup olmadýðý (anormal pozisyon, yer darlýðý, düþmemiþ süt diþi, süpernümerer diþ, odontom varlýðý) da kayýt altýna alýnmýþtýr. Çalýþmadaki tüm parametreler için tanýmlayýcý istatistikler hesaplanmýþtýr. Kategorik deðiþkenler arasý iliþkilerin saptanmasýnda ki-kare testi kullanýlmýþ olup, p<0.05 seviyesinde anlamlý kabul edilmiþtir.
BULGULAR: Sürmemiþ 250 diþin KIBT kesitlerinde GK görülme sýklýðý %75.6 (n=189)’dýr. GK varlýðý ile diþlerin sürmesi arasýnda pozitif yönde anlamlý bir iliþki bulunmuþtur (p<0.001). Normal sürme gösteren 166 diþte GK görülme sýklýðý %83.1 (138/166), sürme dönemi gecikmiþ-gömülü kalmýþ 84 diþte GK görülme sýklýðý %60.7’dir (51/84). Diþlerin gömülü kalmasýnda en büyük faktör %21.6 (n=54) ile anormal pozisyonda bulunmalarý olmuþtur.
TARTIÞMA ve SONUÇ: GK varlýðýnda diþlerin anlamlý olarak sürme eðilimi gösterdiði; yokluðunda ise diþlerin gömülü kalma eðiliminde bulunduðu görülmüþtür.

INTRODUCTION: The aim of this study was to determine the presence of gubernacular canal (GC) in unerupted teeth in cone-beam computed tomography (CBCT) sections and to reveal the relationship between tooth eruption and GC.
METHODS: From 105 individuals, 250 teeth which were delayed erupted-impacted or in normal eruption were examined. All impacted teeth in the maxilla and mandible were included in the study. The teeth were classified as non-existent or existent in terms of GC presence. It was also recorded whether the examined teeth had eruption obstacles (abnormal position, narrow space, retentive primary tooth, supernumerary tooth, odontoma). Descriptive statistics were calculated for all parameters in the study. Chi-square test was used to determine the relationships between categorical variables and it was considered significant at p<0.05.
RESULTS: The overall detection rate of GC in CBCT sections of unerupted 250 teeth was 75.6%. A significant positive correlation was found between the GC and tooth eruption (p<0.001). The presence of GC in 166 teeth showing normal eruption was 83.1% (138/166), and the presence of GC in 84 teeth with delayed eruption-impacted period was 60.7% (51/84).
DISCUSSION AND CONCLUSION: In the presence of GC, teeth tended to erupt significantly; in the absence of GC teeth tended to remain impacted.
