Abstract (2. Language): 
The purpose of this study was to assess the prevalence and distribution of congenially missing permanent teeth, excluding the thrrd molars in B/acksea region children. Panoramic radiographs of 981 children (493 girls and 488 boys) between the ages of 6 and 12 years were examined in terms of congenttally missing permanent teeth. The data were statisticalty evaluated by Chi-Square ve t-test. The prevalence of congenttalty missing permanent teeth was 8.5% (7.7% for boys, 9.5% for girls) with no statistically significant difference between the sexes. The most commonly missing teeth were the mandibular second premolars, followed by the maxiilary lateral incisors, and the maxi/aary second premolars. Symmetrical hypodontia was predominant, and the most commonly symmetrical hypodontia was mandibular second premolar agenesis. Congenttally missing permanent teeth was observed more than mandibula to maxilla but there were no statistically significant difference between the jaws. The distribution of missing teeth was similar between the right and the left sides of the dental arches in each group of children. As a conclusion the determination of congenttalty missing permanent tooth in early period is important in terms of implementation of alternative treatment methods.

Bu çalışmanın amacı; Karadeniz bölgesi çocuklarında, üçüncü büyük azı dişleri dışındaki, daimi dişlerin konjenital o/arak ekskkiiğnnnn prevalansını ve dağılımını beiirlemektir. Bu amaçla, 6-12 yaşaar arasındaki 981 çocuk hastanın (488 erkek, 493 kız) panoramik radyografları konjenttal daimi diş eksikiiği açısından değerlendirildi. Elde edilen veriler istatistiksel o/arak Chi-Square ve t-testi ile değerlendirildi. Araştırmada konjenttal daimi diş eksikiiği prevalansı % 8,5 oaarak bulundu (kzaarda %9,5 ve erkeklerde %7,7) ve cinsiyete göre istatistiksel fark gözlenmedi. En sık eksikiiği gözlenen diş/er sırası lle; alt ikinci küçük azı, üst yan kesici ve üst ikinci küçük azı o/arak tesptt edildi. Diş ekskkiiğnnnn sıklık/a simetrik olarak izlendiği, en sık simetrik diş eksikliğinin ise, alt ikinci küçük azı dişlerinde meydana geldiği belir/endi. Konjenttal daimi diş eksikliği alt çenede üst çeneye göre daha fazaa gözlenmesine rağmen, istatistiksel fark bulunamadı. Her iki grupta da sağ ve sol çene/erdeki eksik diş dağılım/arı ise benzer bulundu. Sonuç oaarak çocuk/ardaki diş eksikliği prevalansının erken dönemde belirlenmesi atternatff tedavi yaklaşımları açısından önemiidir.
