Abstract

Background: In the literature, the relationship of the mandibular cortical index (MCI) with the stage and grade of periodontitis has not yet been investigated. This study aimed to examine the relationship between the stage and grade of periodontitis and MCI according to the current classification of periodontal disease.
Methods: A total of 199 patients (119 females, 80 males) were included in this study. The study population consisted of patients with periodontitis and controls without periodontitis. The stage and grade of the patients with periodontitis were determined according to the criteria of the “2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions”. For this classification, patient records, including periodontal data and panoramic radiographs were used. The MCI values of the patients were also recorded by evaluating the same panoramic radiograph. The Pearson chi-square test was used to compare categorical data according to groups, and multiple comparisons were undertaken with the Bonferroni-corrected Z test.
Results: The non-periodontitis (NP) group had the highest C1 type bone rate (p<0.001). The C3 rate of the stage Ⅲ/Ⅳ group was significantly higher compared to all the remaining groups (stage Ⅰ, stage Ⅱ, and NP) (p<0.001). The C3 rate was significantly higher in the grade C group than in the grade B and NP groups (p<0.001).
Conclusions: The data obtained from this study suggest that there is a positive relationship between the stage and grade of periodontitis and MCI.

Mandibular Kortikal İndeks ile Periodontitis Evre/Derecesi Arasındaki İlişki: Retrospektif Radyografik Çalışma

Abstract

Amaç: Mandibular kortikal indeks (MKİ), mandibular kemik mineral yoğunluğunu değerlendirmek için kullanılan radyomorfometrik indekslerden biridir. Mandibular kortikal indeksinin (MKİ) periodontitisin evresi ve derecesi ile ilişkisi literatürde henüz araştırılmamıştır. Bu retrospektif çalışmada, periodontal hastalığın mevcut sınıflandırmasına göre periodontitisin evresi ve derecesi ile MKİ arasındaki ilişkinin incelenmesi amaçlanmıştır.
Gereç ve Yöntemler: Bu çalışmaya 119’u kadın, 80’i erkek olmak üzere toplam 199 hasta dahil edilmiştir. Çalışma popülasyonu periodontitisli hastalar ve periodontitisi olmayan kontrol hastalarından oluşmuştur. Periodontitisli hastaların evresi ve derecesi “2017 Dünya Periodontal ve Peri-İmplant Hastalıkların ve Durumlarının Sınıflandırılması Çalıştayı” kriterlerine göre belirlenmiştir. Bu sınıflandırma için klinik periodontal verileri ve panoramik radyografileri içeren hasta kayıtları kullanılmıştır. Aynı panoramik radyografi değerlendirilerek hastaların MKİ değerleri de kaydedilmiştir. İstatistiksel analizde kategorik verilerin gruplara göre karşılaştırılmasında Pearson ki-kare testi kullanılırken, çoklu karşılaştırmalar ise Bonferroni düzeltmeli Z testi ile yapılmıştır.
Bulgular: Periodontitis olmayan (NP) grup en yüksek C1 tipi kemik oranına sahip olarak belirlenmiştir (p<0,001). Evre Ⅲ/Ⅳ grubunun C3 oranı diğer tüm gruplara (evre Ⅰ, evre 2 ve NP) göre anlamlı derecede yüksek bulunmuştur (p<0,001). C3 oranı C derece grubunda B ve NP gruplarına göre anlamlı derecede yüksektir (p<0,001).
Sonuçlar: Bu çalışmadan elde edilen veriler periodontitisin evresi ve derecesi ile MKİ arasında pozitif bir ilişki olduğunu göstermektedir.
