Objective: This study aims to compare the real width/length ratio of the maxillary anterior teeth with values obtained through Chu's probe and to assess periodontal parameters. Material and Methods: 128 individuals with Class I occlusion and no need for orthodontic treatment were included. Maxillary incisor width and length were measured using calipers and Chu's probe. Keratinised gingival height, pocket depth, gingival thickness and need for gingivectomy were also measured. Statistical analyses were performed using the independent samples t-test for continuous variables, the chi-squared test for categorical variables, and the kappa statistic for method comparisons. Results: No significant difference between methods was observed for each tooth. Highest keratinized gingiva amount was in upper left lateral incisor in females (5.141±1.46) and upper right lateral incisor in males (5.542±1.55). The tooth with the deepest pocket depth was upper left canine in females (2.301±0.54) and upper right canine (2.40±0.58) and upper left canine (2.40±0.63) in males. Thin phenotype was common in upper right lateral incisor in females (n=46), while thick phenotype was seen in upper right central incisor (n=30) and upper left lateral incisor (n=30). Teeth with highest and lowest gingivectomy needs were upper left canine in females (n=37) and upper right lateral incisor (n=11), and upper left central incisor (n=28) and upper left lateral incisor (n=10) in males, respectively. Conclusion: When the crown width-to-height ratio is 0.78 in terms of aesthetics, Chu's probe is practical in clinical use and gives similar results to caliper measurements.

Amaç: Bu çalışmanın amacı üst çene anterior dişlerin gerçek genişlik/uzunluk oranını ile Chu'nun sondu ile elde edilen değerlerle karşılaştırmak ve diş eti parametrelerin değerlendirilmesidir. Gereç ve Yöntemler: Çalışmaya ortodontik tedaviye ihtiyacı bulunmayan sınıf I oklüzyona sahip 128 birey dâhil edildi. Bireylerin maksiller kesici dişlerinin genişlik ve uzunlukları hem kumpas hem de Chu'nun sondu ile ölçüldü. Ayrıca ölçüm yapılan dişlerin keratinize diş eti yüksekliği, cep derinliği, diş eti kalınlığı ve gingivektomi ihtiyaçları belirlendi. Sürekli değişkenler bakımından bağımsız örneklem t-testi, kategorik değişkenler için ki-kare test, yöntemlerin karşılaştırılması için ise Kappa istatistik yöntemleri elde edilen verilerin istatistiksel karşılaştırılması için kullanıldı. Bulgular: Ölçümü yapılan her diş için yöntemler arasında istatistiksel olarak anlamlı bir fark gözlenmedi. En yüksek keratinize diş eti miktarı kadınlarda üst sol yan kesici dişte (5,141±1,46), erkeklerde ise üst sağ yan kesici dişte (5,542±1,55) gözlendi. Cep derinliğinin en yüksek olduğu diş, kadınlarda üst sol köpek diş (2,301±0,54), erkeklerde ise üst sağ köpek (2,40±0,58) ve üst sol köpek (2,40±0,63) dişleri oldu. Diş eti kalınlığı açısından, kadınlarda ince fenotip en çok üst sağ yan kesici dişte (n=46); kalın fenotip ise üst sağ orta kesici diş (n=30) ve üst sol yan kesici dişinde (n=30) gözlendi. Gingivektomi ihtiyacı en yüksek ve en düşük olan dişler sırasıyla kadınlarda üst sol köpek diş (n=37) ve üst sağ yan kesici diş (n=11), erkeklerde ise üst sol orta kesici diş (n=28) ve üst sol yan kesici diş (n=10) olarak bulundu. Sonuç: Estetik açıdan kron genişlik-yükseklik oranı 0,78 olduğunda Chu'nun sondu klinik kullanımda pratiktir ve kumpas ölçümlerine benzer sonuçlar verir.
