Amaç: Farklı iskeletsel maloklüzyona sahip hastalarda maksiller orta hat diastemasının ve dental orta hat sapmasının dağılımının incelenmesi ve iskeletsel maloklüzyon farklılığının, hem sagital hem de vertikal yön belirleyici parametrelere göre maksiller orta hat diastemasının ve dental orta hat sapmasının oluşmasında etiyolojik bir faktör olup olmadığının araştırılmasıdır. Gereç ve Yöntemler: Diş Hekimliği Fakültesi Ortodonti Kliniğine başvuran kraniyofasiyal anomalisi bulunmayan, ortodontik tedavi görmemiş ve travma öyküsü olmayan, yaş aralığı 11-18 yıl olan 230 hasta (83 erkek, 147 kadın) çalışmaya dâhil edildi. Bireyler ANB ve SN-GoGN açılarına göre gruplara ayrıldı. Varolan maksiller orta hat diasteması ve dental orta hat sapması (hem üst hem alt dental orta hat sapması beraber görülen hastalar) incelendi. Bilgileri değerlendirmek için tanımlayıcı analizler ve Pearson ki-kare testi kullanıldı. Elde edilen veriler %5 anlamlılık seviyesinde istatistiksel olarak analiz edildi. Bulgular: Yaş aralığı 11-18 yıl olan 230 birey ANB ve SN-GoGN açılarına göre gruplara ayrıldı. Maksiller orta hat diasteması ve dental orta hat sapması incelendi. İki yüz otuz hastanın 107 (%46,5)'si iskeletsel sınıf I, 69 (%30)'u iskeletsel sınıf II ve 54 (%23,5)'ü iskeletsel sınıf III olarak belirlendi. Otuz yedi (%16,1) hasta hipodiverjan, 98 (%42,6) hasta normodiverjan ve 95 (%41,3) hasta hiperdiverjan idi. Kırk dokuz (%21,3) hastada orta hat diasteması, 158 (%68,7) hastada orta hat sapması mevcuttu. Sonuç: Bu çalışmada, farklı iskeletsel maloklüzyonlarda maksiller orta hat diasteması ve orta hat sapmasının dağılımın farklılık göstermediği saptanmıştır. Maksiller orta hat diastemasının ve dental orta hat sapmasının iskeletsel maloklüzyon dışında farklı etkenlerden de kaynaklanabileceği düşünülmektedir.

Objective: To investigate the distribution of maxillary midline diastema and dental midline deviation in patients with different skeletal malocclusion and to investigate whether the skeletal malocclusion difference is an etiological factor in the formation of maxillary midline diastema and dental midline deviation according to both sagittal and vertical directive parameters. Material and Methods: The study involved 230 (83 boys, 147 girls) patients (11-18 years) having no craniofacial anomalies, previous orthodontic treatment or trauma history. The individuals were divided into groups based on ANB and SN-GoGN angles. Presences of maxillary midline diastema and dental midline deviation (cases with both upper and lower dental midline deviation) were examined. Descriptive statistics and chi-square test were used to evaluate the data. Results: Of the patients, 107 (46.5%) were skeletal class I, 69 (30%) were skeletal class II, and 54 (23.5%) were skeletal class III while 37 (16.1%) were hypodivergent, 98 (42.6%) were normadivergent, 95 (41.3%) were hiperdivergent. 49 (21.3%) patients had midline diastema and 158 (68.7%) patients had midline deviation. There were not statistically significant differences in the distribution of midline diastema and dental midline deviation between different skeletal patterns. Conclusion: Although patients have several malocclusions, some of them are associated with different skeletal patterns. In this study, the distribution of maxillary median diastema and dental midline deviation did not differ in different skeletal malocclusion.
