Mandibuler İnsiziv kanal ve Lingual Foramen Özelliklerinin Dental Volumetrik Tomografi (DVT) ile İncelenmesi

AMAÇ: Mandibular insiziv kanal ve lingual foramenin varlığı, sayısı ve boyutlarını dental volümetrik tomografi (DVT) ile incelemektir. YÖNTEM: 31 adet kuru insan mandibulası mandibular alt kenar yer düzlemine paralel konumda yerleştirilerek DVT ile görüntülendi. Görüntüler mandibular insiziv kanal (MİK) ve lingual foramen (LF) varlığı, boyutları ve antero-posterior uzunluğu yönünden değerlendirildi. Ek olarak, lingual foramenlerin labial ve lingual yükseklikleri saptandı. Lingual foramenler genial tüberkülün üstünde veya altında yer almasına göre de sınıflandırıldı. BULGULAR: MİK görüntülerin %58'inde belirlendi. İnsiziv kanalın ortalama çapı 2,79mm iken ortalama uzunluğu 2,88mm olarak ölçüldü. Otuzbir mandibulada toplam 60 LF saptandı. Bunların 28'i (%47) genial tüberkülün üstünde; 32'si ise (%53) altında yer almaktaydı. LF'e ait kanallar %30 oranında tek, ve sırasıyla %50 ve %20 oranında iki ve üç tane idi. Kanalların ortalama lingual çapı 0,68mm, labial çapı ise 0,63mm bulundu. Ortalama labial ve lingual yükseklikler sırasıyla 10,57mm ve 9,53mm olarak saptandı. SONUÇ: Mandibular insiziv kanal, lingual foramen ve ilişkili sinir damar paketleri sayı, lokalizasyon ve boyutları açısından değişkenlik göstermektedir. Dolayısı ile bu anatomik yapıların varlığı ve özelliklerinin kişi bazında incelenmesi önerilmektedir.

Characterıstics of Mandibular Incisive canal and Lingual foramen Using Dental Volumetric Tomography (DVT)

OBJECTIVE: To investigate the presence, location and the dimensions of incisive canal and lingual foramen using dental volumetric tomography (DVT). METHODS: Thirty-one dry human mandibles were exposed using a DVT system. Images were examined for the presence of mandibular incisive canal (MIC) and lingual foramina (LF) including their dimensions and anterior-posterior lengths. In addition; labial and lingual diameters and heights of LF was determined. LF were classified with respect to the mental spine as well. RESULTS: MIC was observed in 58% of the images with mean diameter of 2.79mm while the mean length was 2.88mm. Total of 60 LF were observed in 31 mandibles. Twenty eight (47%) of them were located superior while 32 (53%) were located inferior to the genial spines. Only one canal was observed in 30% of the LFs whereas 50% of LFs had two and 20% had three canals. The mean lingual and labial diameters of the LF canals were 0.68mm and 0.63mm respectively. The mean height was 10.57mm and 9.53mm at the lingual and labial sides. CONCLUSION: The MIC, LF and associated neurovascular bundles may show many variations in number, location and size. Therefore, particular evaluation of these structures for each case is recommended.
