Abstract

PURPOSE: To evaluate the effect of edentulism on radiomorphometric indices by measuring the panoramic mandibular index (PMI), mandibular cortical index (MCI) and mental index (MI) values bilaterally in Kennedy class I and II cases. MATERIAL AND METHODS: PMI, MCI and MI values were measured bilaterally on a total of 128 digital panoramic radiographs, 64 of which belonged to class I and 64 to class II patients. Two independent group comparisons were made with an independent two-sample t-test or Pearson Chi-square test. The appropriate tests were chosen out of two dependent t test and McNemar Bowker to compare left and right or edentulous and dentate cases. The relationship between age and MCI was analyzed using the Spearman rank correlation coefficient, and the relationship between the PMI and MI variables was analyzed using the Pearson correlation coefficient. (p<0.05) in the statistical analyzes were performed in both directions. RESULTS: In Kennedy class I cases, no difference was observed between MCI scores and PMI and MI values on the right and left sides (p>0.05). The distribution of MCI in the edentulous and dentate regions differed in Kennedy class II cases (p=0.002). Variable values of PMI and MI obtained from the dentate and edentulous sides were also found to differ (p<0.05). In class I and II comparison, MI value was found to be significantly higher in class I (p=0.003). CONCLUSION: MCI, PMI and MI values differ according to the presence or absence of teeth.

Abstract

AMAÇ: Kennedy sınıf I ve II olgularında panoramik mandibular indeks (Panoramic Mandibular Index;PMI), mandibular kortikal indeks (Mandibular Cortical Index;MCI) ve mental indeks (Mental Index;MI) değerlerini bilateral olarak ölçerek dişsizliğin radyomorfometrik indeksler üzerindeki etkisini değerlendirmektir. GEREÇ VE YÖNTEM: 64 adet sınıf I, 64 adet sınıf II olmak üzere toplam 128 dijital panoramik radyograf üzerinde PMI, MCI ve MI değerleri bilateral olarak ölçüldü. Bağımsız iki grup karşılaştırması bağımsız iki örnek t testi veya Pearson Ki-kare testi ile yapıldı. Sınıf I’ de sağ-sol ve Sınıf II’ de dişsiz-dişli taraf karşılaştırmalarında bağımlı iki ölçüm t testi ve McNemar-Bowker testlerinden uygun olan yöntem kullanıldı. Yaş ile MCI arasındaki ilişki Spearman sıra korelasyon katsayısı, PMI ve MI değişkenleriyle ilişki Pearson korelasyon katsayısı ile incelendi. (p<0.05) değeri istatistiksel olarak anlamlı kabul edildi. BULGULAR: Kennedy sınıf I vak’alarında sağ ve sol tarafta MCI skorlaması ile PMI ve MI değerleri arasında fark gözlenmemiştir (p>0.05). Kennedy sınıf II vak’alarında dişli ve dişsiz bölgede MCI dağılımı farklılık göstermiştir (p=0.002). Dişli ve dişsiz taraftan elde edilen PMI ve MI değişken değerlerinin de farklılık gösterdiği tespit edilmiştir (p<0.05). Sınıf I ve II karşılaştırmasında MI değeri sınıf I’de anlamlı derecede yüksek bulunmuştur (p=0.003). SONUÇ: MCI, PMI ve MI değerleri diş varlığı veya yokluğu durumuna göre farklılık göstermektedir.
