Özet
AMAÇ: Dentogingival kompleksi oluştuan yapıların boyutları ve birbirleriyle ilşikileri, doğru birşekilde kolayca belirlenememesi nedeniyle büyük ölçüde göz ardı edilmiştir. Bu çalışmanın amacı kuron boyu operasyonları öncesinde mine sement sınırının yerinin yumuşak doku bilgisayarlı tomografi (ST-CBTC) ile belirlenmesi ve post operatif dönemde dişetinin fenotipine bağlı olarak periodontal dokularda oluşabilecek pozisyonel değişiklikleri değerlendirmektir. GEREÇ YÖNTEM: Prospektif olarak hazırlanan bu klinik çalışmada 14 hasta ve 88 bölge dahil edildi ve 6 ay boyunca takip edildi. Tüm ağız sondalama derinliği (SD), plak indeksi (PI) ve sondalamada kanama (SK) değerleri ile birlikte klinik kuron boyu uzunluğu (A), dişeti kenarı ile mine sement sınırı arası mesafe (B), mine sement sınırı ile alveol kemik arası mesafe (C), diş eti kalınlığı (D) ve keratinize diş eti genişliği (E) klinik olarak değerlendirildi. ST-CBCT görüntülemesi esnasında hastalara plastik bir dudak ekartörü kullandırıldı ve dillerini ağızlarının tabanına doğru çekmeleri istendi. A, B, C, D ve E parametreleri, başlangıçta ST-CBCT görüntülerinde de ölçüldü. BULGULAR: Çalışma grubunun yaş ortalaması 36,8 ± 15,3 yıl, tüm ağız PD, PI ve SK sırasıyla 22 ± 0,40 mm, % 12,3 ± 0,93 ve 7,22 ± 0,87 olarak saptandı. A ölçümlerinin ortalaması klinik ve ST-CBCT ölçümü arasında anlamlı farklılık göstermedi (p> 0.05). C, ST-CBCT'de klinik ölçümlerden anlamlı olarak daha yüksekti (sırasıyla 2,64 ± 1,00 mm ve 3,01 ± 0,97 mm; p <0,001). C, ST-CBCT ölçümlerinde hem kalın hem de ince fenotiplerde klinik ölçümden anlamlı olarak daha yüksekti (sırasıyla p <0.001 ve p = 0.018). Bununla birlikte, E hem ince hem de kalın fenotiplerde başlangıçtan 6 aya kadar anlamlı bir şekilde azaldı (p = 0.017). SONUÇ: ST-CBCT, mine sement sınırını görselleştiren ve estetik kron boyu uzatma ameliyatı için önemli olan mine sment sınırı ile alveol kemik arası mesafeyi (C) ölçen etkili, invazif olmayan bir tanı yöntemidir. Bu teknik, klinisyenler için estetik kuron boyu uzatma ameliyatında prosedürlerin planlanması ve uygulanmasında yardımcı olabilir.

Aim: The dimensions and relationships of the structures of the dentogingival unit have been greatly overlooked because of the inability to easily and precisely determine them. The purpose of the present study was to use a soft tissue cone-beam computed tomography (ST-CBCT) to evaluate the positional changes of the periodontal tissues, particularly the biological width and relationships of the structures of the dentogingival unit following Aesthetic crown lengthening surgery. Materials and Methods: In the present prospective clinical study, fourteen patients and 88 regions were treated and followed up for 6 months. The evaluated clinical parameters were full mouth probing depth (PD), plaque index (PI) and bleeding on probing (BOP), clinical crown length (A), Gingival margin to cemento-enamel junction (B), cemento-enamel junction to alveolar bone crest distance (C), gingival thickness (D) and gingival width (E). The ST-CBCT scans were obtained from the patients those wore a plastic lip retractor and retracted their tongues toward the floor of their mouths. The parameters of A, B, C, D and E were measured in the ST-CBCT scans and baseline. Results: The mean age of the study group was 36.8±15,3 years and full mouth PD, PI and BOP was 22±0,40mm, %12,3±0,93 and 7,22±0,87; respectively. Average of A measurements were not significantly different between clinical and ST-CBCT scan measurement (p>0.05). C was significantly higher in ST-CBCT than clinical measurements (2,64±1,00mm and 3,01±0,97mm;p<0.001, respectively). C was significantly higher in ST-CBCT scans than clinical measurement in both thick and thin phenotypes (p<0.001 and p=0.018, respectively). Concomitantly, GW significantly decreased from baseline to 6 months in both thin and thick phenotypes (p=0.017). Conclusion: ST-CBCT is an effective, noninvasive diagnostic method to visualize the cemento-enamel junction and measure the cemento-enamel junction to alveolar bone crest distance (C), which is important for aesthetic crown lengthening surgery. This technique may helpful for clinicians in the planning and execution of procedures in aesthetic crown lengthening surgery. KEY WORDS: Dentogingival Junction, Aesthetic crown lengthening, ST-CBCT
