Hubungan Variasi Morfologisella Tursikadengan Maloklusi Klas III Skeletal di RSGMP FKG USU

Abstract

Background: The sella turcica is one of the commonly used orthodontic landmarks in determining and diagnosing various problems of the facial skeleton. The purpose of this study was to determine relationship between the morphology of sella turcica and Class III malocclusion in Indonesia specially in RSGMP FKG USU Medan. Materials and Methods: The sample in this study 104 lateral lateral cephalograms with range age 17-35 years old and were divided into two groups. First group consisted of 52lateral cephalograms with Class I malocclusion and the second groupconsisted of 52 lateral cephalograms with Class III malocclusion.The morphology of sella turcica was analysed based on theory Axelsson et al.Result: Sellaturcica with normal morpholoy with greater found in Class I malocclusion (67,3 % of the subjects) and inClass III maloclusion only 17,3 % of the subjects with normalmorphology.Bridging of the sellaturcica with greater found in Class III malocclusion (30,8 % of the subjects) and inClass Imaloclusion only found 13,5 %.Conclusion: There was a significant difference between morphology of sella turcica in Class III malocclusion and morphology of sella turcica in Class I malocclusion. There was relationship between morphology of sella turcica and Class III malocclusion

LatarBelakang:Sella tursika merupakan struktur anatomi yang umum digunakan dalam bidang ortodonti untuk pengukuran sefalometri, evaluasi morfologi kraniofasial, relasi hubungan rahang dengan kraniumdan superimposisi serial sefalometri.Tujuanpenelitianiniadalahuntukmengetahuihubungan variasi morfologisellatursikadengan maloklusi Klas III skeletal padapasien di Indonesia, khususnya di RSGMP FKG USU Medan.Bahandan Cara: Penelitian ini dilakukan pada 104 sampel dimana terdiri dari dua kelompok sampel yang masing-masing berjumlah 52 sampeldengan rentangusia17-35 tahun. Kelompok pertama yaitu foto rontgen sefalometri lateral dengan maloklusi Klas I skeletal dan kelompok kedua yaitu foto rontgen sefalometri lateral dengan maloklusi Klas III skeletal.Untuk melihat variasi morfologi sella tursika dilakukan tracing sefalometri lateral berdasarkan penelitian Axelsson dkk. Hasil: Morfologi normal sellatursika paling banyakdijumpaipadakelompokKlas I skeletal yaitusebanyak 35 sampel (67,3 %) sedangkanpadakelompokKlas III skeletal yaituhanya 9 sampel (17,3 %).VariasimorfologisellatursikapadakelompokmaloklusiKlas III skeletal paling banyakdijumpaiyaitubridgingsebanyak 16 sampel (30,8 %), sedangkanpadakelompokmaloklusiKlas I skeletal bridgingdijumpaisebanyak7sampel (13,5 %).
