Quantitative Assessment of Periodontal Inflamed Surface Area in Patients with Periodontitis

Abstract

Objective: The Periodontal Inflamed Surface Area (PISA) enables quantification of periodontal inflammatory burden by translating clinical periodontal findings into a surface area metric. The present retrospective study aimed to calculate PISA values in individuals diagnosed with Stage III Grade B and Stage III Grade C periodontitis and to evaluate the associations between PISA and conventional periodontal clinical parameters. Material and Methods: Healthy individuals as well as patients with Stage III Grade B and Stage III Grade C periodontitis were evaluated for periodontal parameters. PISA scores were calculated based on bleeding on probing positive sites and probing depth. Correlations between PISA values and periodontal clinical parameters were analyzed statistically. Results: Significant differences in PISA values were observed among healthy individuals and Stage III Grade B and Grade C periodontitis patients, with the highest values were found in Grade C periodontitis. PISA values were positively correlated with bleeding on probing (BOP), probing depth (PD), and plaque index (PI) indicating an increase in inflammatory burden with greater periodontal tissue breakdown. Conclusion: PISA provides a robust quantitative representation of periodontal inflammation and demonstrates strong associations with established clinical periodontal parameters. These findings highlight the value of PISA as a complementary outcome measure for assessing periodontal inflammatory burden and disease severity in periodontitis.

Periodontitisli Bireylerde Periodontal İnflame Yüzey Alanının Kantitatif Değerlendirilmesi

Abstract

Amaç: Periodontal inflame yüzey alanı (PİYA), klinik periodontal bulguları bir yüzey alanı ölçütüne dönüştürerek periodontal enflamatuvar yükün nicel olarak değerlendirilmesine olanak sağlar. Bu retrospektif çalışmanın amacı, Evre III Derece B ve Evre III Derece C periodontitis tanısı almış bireylerde PİYA değerlerini hesaplamak ve geleneksel periodontal klinik parametreler arasındaki ilişkileri değerlendirmektir. Gereç ve Yöntemler: Sağlıklı bireyler ile Evre III Derece B ve Evre III Derece C periodontitisli hastaların periodontal klinik parametreleri değerlendirildi. PİYA skorları, sondalamada kanama pozitif alanlar ve sondalama derinliği esas alınarak hesaplandı. PİYA değerleri ile klinik periodontal parametreler arasındaki korelasyonlar istatistiksel olarak analiz edildi. Bulgular: PİYA değerleri, sağlıklı bireyler ile Evre III Derece B ve Derece C periodontitis hastaları arasında anlamlı farklılıklar göstermiş olup, en yüksek değerler Derece C periodontitiste saptanmıştır. PİYA değerlerinin sondalamada kanama (BOP), sondalama derinliği (PD) ve plak indeksi (PI) ile pozitif yönde ilişkili olduğu ve periodontal doku yıkımı arttıkça enflamatuvar yükün de arttığı belirlenmiştir. Sonuç: PİYA, periodontal enflamasyonun nicel olarak değerlendirilmesini sağlayan güçlü bir ölçüt olup, klinik periodontal parametrelerle anlamlı ilişkiler göstermektedir. Bu bulgular, PİYA’nın periodontitiste enflamatuvar yükün ve hastalık şiddetinin değerlendirilmesinde tamamlayıcı bir sonuç ölçütü olarak değerini ortaya koymaktadır.
