RELATIONSHIP BETWEEN SELLA TURCICA BRIDGING AND MAXILLARY IMPACTED CANINES AND MAXILLARY PARAMETERS

Öz

Aim: To evaluate the relationship between the cases of normal sella turcica, partial and total sella turcica bridging (STB) and unilaterally and bilaterally impacted canines and maxillary parameters. Material and Methods: The sample of the study was divided into three groups according to the calcification status of the sella turcica. A total of 260 patients (80 normal sella turcica,102 partial bridging and 78 total bridging cases) were included in the study. Maxillary cephalometric measurements were performed. The results were evaluated on the significance level of p<0.05. Results: There was no significant relationship between sex and impacted canine teeth and the STB groups. The relationship between the STB groups and impacted canines was also not significant. There were no significant differences based on age and effective midface length (Co-A) among the impacted canine groups, while these groups had significantly different values of maxillary base length (ANS-PNS), the angle of the maxillary plane (PP/SN) and middle third facial height (N-ANS). A statistically significant relationship was found between the STB groups and the variables of Co-A, ANS-PNS, PP /SN and N-ANS. Conclusions: The Co-A, ANS-PNS, PP/SN and N-ANS cephalometric measurements were found to be higher in partial STB. Furthermore, the mean ANS-PNS, PP/SN and N-ANS values of the unilaterally impacted canine teeth were higher than those of the bilaterally impacted canine teeth. The relationship between the STB groups and the impacted canine variables was not statistically significant. Keywords: sella turcica, sella turcica bridging, impacted canine, maxilla Sella Tursika Köprüsü İle Üst Gömülü Kanin Ve Maksilla Arasındaki İlişki Amaç :Normal sella tursika, parsiyel ve tam sella tursika köprüsü (STB) ile tek taraflı ve bilateral üst gömülü kanin dişler ve maksilla arasındaki ilişkiyi değerlendirmektir. Gereç ve Yöntem: Çalışma sella tursikanın kalsifikasyon durumuna göre üç gruba ayrılmıştır. Çalışmaya toplam 260 hasta (80 normal sella tursika, 102 parsiyel ve 78 tam köprü) dahil edilmiştir. Maksiller sefalometrik ölçümler yapılmıştır. Sonuçlar p<0.05 anlamlılık düzeyinde değerlendirilmiştir. Bulgular: Cinsiyet ve gömük kanin dişler ile STB arasında istatistiksel olarak anlamlı bir ilişki bulunmamıştır. STB grupları ile gömük kanin diş değişkenleri arasındaki ilişki de istatistiksel olarak anlamlı değildir. Gömük kanin diş grupları maksiller palatal düzlem (ANS-PNS), maksiller düzlem açısı (PP / SN), orta yüz yüz uzunluğu (N-ANS) değişkenleri ile anlamlı ilişkili bulunmuşken, yaş ve efektif orta yüz uzunluğu (Co-A) açısından anlamlı farklılık göstermemiştir. STB grupları ile Co-A, ANS-PNS, PP / SN ve N-ANS değişkenleri arasında istatistiksel olarak anlamlı bir farklılık bulunmuştur. Sonuç: Parsiyel STB'de Co-A, ANS-PNS, PP / SN ve N-ANS sefalometrik ölçümleri daha yüksek olduğu bulunmuştur. Ayrıca, tek taraflı gömük kanin dişlerin ortalama değerleri ANS-PNS, PP / SN, N-ANS değerleri , bilateral gömük kanin dişlerinden daha fazla bulunmuştur. STB grupları ile gömük kanin diş değişkenleri arasındaki ilişki istatistiksel olarak anlamlı bulunmamıştır. Anahtar Sözcükler : sella tursika, sella tursika köprüsü,gömük kanin, maksilla
