Abstract

ABSTRACT
Objective: The objective of the study is to evaluate the fenestration and dehiscence types in Turkish human skulls according to 2 classifications.
Methods: For the study, 297 skulls with 1808 teeth were analyzed from a collection of anat- omy laboratories of 2 universities. Yang’s and Pan’s classifications were used to determine fenestration and dehiscence types. Chi-square and Fisher’s exact tests were used for statisti- cal analysis.
Results: There was no statistical difference in the presence of fenestration and dehiscence between the maxilla and mandible (P > .05). Type IV was most common fenestration in the maxilla (P = .029). Types III and IV were the most common types in the mandible (P < .05). CI DI and CI DII were the most common dehiscence in the maxilla and mandible, respec- tively (P < .05). The maxillary first premolar showed the highest prevalence of fenestration (P < .001). The mesial root of the maxillary first molar showed the highest prevalence of dehiscence (P < .05).
Conclusion: The prevalence of fenestration and dehiscence was 8.70% and 10.06%, respectively, in Turkish human skulls. Fenestration in maxilla were mostly located in middle and apical of the root (type IV), the ones in mandible were in the coronal third of the root (type III). The most affected tooth was the maxillary first premolar for fenestration and the maxillary first molar for dehiscence. Most dehiscences in the maxilla were located in the coronal (CI DI), and they were located in both the coronal and middle thirds (CI DII) in the mandible.

ÖZ
Amaç: Çalışmanın amacı Türk insan kuru kafataslarındaki dehisens ve fenestrasyon tiplerini iki sınıflamaya göre değerlendirmektir.
Yöntemler: Çalışma için iki üniversitenin anatomi laboratuvarlarının koleksiyonundan 1808 dişe sahip 297 kafatası analiz edildi. Fenestrasyon ve açılma tiplerinin belirlenmesinde Yang ve Pan’ın sınıflandırmaları kullanıldı. İstatistiksel analizde ki-kare ve Fisher exact testleri kullanıldı.
Bulgular: Maksilla ve mandibula arasında fenestrasyon ve dehisens varlığı açısından istatistiksel fark bulunamadı (P>.05). Maksillada en sık görülen fenestrasyon Tip IV idi (P=.029). Alt çenede en sık görülen tip III ve IV tipi idi (P<.05). CI DI ve CI DII sırasıyla maksilla ve mandibulada en sık görü- len dehisens tipleriydi (P<.05). Üst birinci küçük azı dişi en yüksek fenestrasyon prevalansını gös- terdi (P<.001). En yüksek dehisens prevalansı ise maksiller birinci moların mezial kökünde görüldü (P<.05).
Sonuç: Türk insan kafataslarında fenestrasyon ve dehisens prevalansı sırasıyla %8.70 ve %10.06 idi. Maksilladaki fenestrasyonların çoğu kökün hem orta hem de apikal üçlüsünde konumlanan tip IV sınıfına aitti. Mandibuladaki fenestrasyonlar ise koronal üçlüde (tip III) yerleşmişti. En çok etkilenen diş grupları; fenestrasyon için üst birinci premolar, ve dehisens için üst birinci molardı. Maksilladaki dehisensin çoğu koronal bölgede (CI DI) konumlanırken, mandibuladakileri çoğu ise hem koronal hem de orta üçlüyü içeren CI DII sınıfına aitti.
