Determination Of Vertical Interproximal Bone Loss Topography: Correlation Between Digital Measurement And Clinıcal Measurement

Öz

Objectives: The aim of this study is to evaluate the clinical value of periodontal bone defects determined by Orthopanthomograph (OPG) and Cone Beam Computed Tomography (CBMT). And to question the reliability of digital radiographs that routinely aid diagnosis and treatment in the clinic by comparing the results.

Materials and Methods: Eskişehir Osmangazi University Faculty of Dentistry Department of Periodontology October 2015 - April 2016 to date of patients who were placed among individuals diagnosed with chronic periodontitis and aggressive periodontitis were included in the study. Radiographic measurements the peak of the defect at the root of the alveolar crest (AC) projection was determined as the base of the apical contour (BD) defect at the root surface of the periodontal ligament. The enamel cementation (CEJ) is taken as a fixed coronal reference for these measurements. Radiographic measurements were made after the above lines were drawn. After radiographic measurements, clinical measurements were made correctly during flap surgery.

Results: According to the findings of this study, OPG and CBCT in the anterior region represented good clinical findings, whereas in the posterior region, measurements with CBCT were found to have excellent correlation in clinical measurements. In addition, CBCT represents better clinical measurements than OPG in evaluating all data. Conclusion: It is more advantageous to use CBCT when it is aimed to make a more accurate judgment in clinically determined critical intrabony defects and to plan more radical treatment.

Vertikal İnterproksimal Kemik İçi Defektlerin Topografisinin Klinik ve Dijital Ölçüm Arasındaki İlişkinin Belirlenmesi

Öz

Amaç: Bu çalışmanın amacı, periodontal kemikiçi defektlerin belirlenmesinde klinik ölçümler ile ortopantomograf görüntüleme (OPG) ve konik ışınlı bilgisayarlı tomografi (KIBT) ile tanı değerini değerlendirmek ve sonuçları karşılaştırarak klinikte rutin olarak teşhis ve tedaviye yardımcı olan dijital radyografilerin güvenilirliğini sorgulamaktır.

Materyal ve Metod: Eskişehir Osmangazi Üniversitesi Diş Hekimliği Fakültesi Periodontoloji Anabilim Dalına Ekim 2015 - Nisan 2016 tarihleri arasında başvuran hastalardan kronik periodontitis ve agresif periodontitis teşhisi konulmuş bireyler çalışmaya dahil edilmiştir. Radyografik ölçümlerde Alveoler kret (AK) projeksiyonunun kök yüzeyine temas ettiği en üst nokta defektin tavanı, periodontal ligamentin kök yüzeyinde izlendiği en apikal kontur defektin tabanı olarak belirlenmiştir. Mine-sement birleşimi (MSB) bu ölçümler için sabit koronal referans olarak alınmıştır. Radyografik ölçümler yukarıda belirtilen çizgiler çizildikten sonra yapılmıştır. Radyografik ölçümlerden sonra, klinik ölçümler flep ameliyatı esnasında ölçülmüştür. 

Bulgular: Bu çalışmanın bulgularına göre anterior bölgede OPG ve KIBT iyi düzeyde klinik bulguları temsil ederken, posterior bölgede ise KIBT ile yapılan ölçümler klinik ölçümlerde mükemmel oranda korelasyon bulunmuştur. Ayrıca tüm verilerin değerlendirilmesinde KIBT klinik ölçümleri OPG’ye oranla daha iyi temsil etmektedir.

Sonuç: Klinik olarak tespit edilmiş kritik kemik içi defektlerde daha kesin yargıya varabilmek ve daha radikal tedavi planlaması yapabilmek amaçlandığında KIBT’den yararlanmak daha avantajlıdır.
