Objective: To determine whether palatal rugae, which are defined as unique and personal characteristic like fingerprints, can be used for purposes such as age estimation and sex determination, palatal rugae were examined in terms of shape, location, direction and number in the sample of Çorum province. This study aimed to evaluate the reliability of the use of palatal ruga research articlee as an additional and supportive method to forensic identification procedures. Material and Methods: In the study, 200 maxilla models, 110 female and 90 male, aged 18-84 years, who applied to Çorum Oral and Dental Health Center for examination and treatment purposes were used. 1,416 palatal rugae in the maxillary jaw models were marked with an acetate pen and measured with a digital caliper with an accuracy of 0.01 mm. The evaluation of palatal ruga measurements included the direction, length, type, fusion patterns, and numbers of the rugae, using the Thomas and Kotze classification system. For shape/orientation assessments, the ''Kapali Classification System'' was employed. This study was carried out following the principles of the Declaration of Helsinki. Results: A statistically significant negative relationship was detected between the number of palatal rugae and age in bothmaleand female (p<0.05). In the distribution of palatal rugae lengths by gender, it was determined that the most common measurement type in both genders was the ''primary (<10 mm) type''. Conclusion: Palatal rugae can be used as a supporting tool in age, gender, resurfacing studies, ethnicity research and forensic identification procedures.

Amaç: Parmak izi gibi eşsiz ve kişiye özgü bir karakteristik olarak tanımlanan palatal rugalarının, yaş tahmini ve cinsiyet tayini gibi amaçlarla kullanılıp kullanılamayacağını saptamak üzere Çorum ili örnekleminde palatal rugalar, şekil, yerleşim, yön ve sayı bakımından incelenmiştir. Bu çalışmada, adli kimliklendirme prosedürlerine ek ve destekleyici bir yöntem olarak palatal rugaların kullanımının güvenilirliğinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmada, muayene ve tedavi amaçları ile Çorum Ağız ve Diş Sağlığı Merkezine başvuran 18-84 yaş aralığındaki 110'u kadın 90'ı erkek olmak üzere 200 adet maksilla modeli kullanılmıştır. Maksiller çene modellerinde bulunan 1.416 palatal rugalar asetat kalemi ile işaretlenmiş, 0,01 mm hassasiyete sahip dijital kumpas vasıtası ile ölçülmüştür. Palatal ruga ölçümlerinin değerlendirilmesinde rugaların yönü, uzunluğu, tipi, birleşme biçimleri ve sayıları Thomas ve Kotze sınıflandırma sistemi, şekil/yön değerlendirmelerinde ise ''Kapali sınıflandırma sistemi'' kullanılmıştır. Bu çalışma Helsinki Deklarasyonu prensiplerine uygun olarak gerçekleştirilmiştir. Bulgular: Hem erkeklerde hem de kadınlarda palatinal ruga sayısı ile yaş arasında istatistiksel olarak negatif yönlü anlamlı ilişki tespit edilmiştir (p<0,05). Palatal ruga uzunluklarının cinsiyete göre dağılımında her iki cinsiyette de en yaygın ölçüm tipinin ''birincil (<10 mm) tip'' olduğu saptanmıştır. Sonuç: Palatal rugalar, yaş, cinsiyet, yeniden yüzeylendirme çalışmalarında, etnik köken araştırmalarında ve adli kimliklendirme işlemlerinde destekleyici bir araç olarak kullanılabilir.
