Publication: Birinci Büyük Azı Dişlerin Dental Gelişimlerinin Ektopikerüpsiyon Üzerine Etkisinin Radyografik Olarak Değerlendirilmesi
Abstract
Amaç: Daimi birinci molar (DBM) dişlerin ektopik erüpsiyonu ile bu dişlerin diş gelişim düzeyi arasındaki ilişkinin radyografik olarak değerlendirilmesidir. Yöntem: Çalışmada Ondokuz Mayıs Üniversitesi Diş Hekimliği Fakültesi'ne başvuran 5-9 yaş arası toplam 15.332 çocuk hastanın (6116 kız, 9216 erkek) panoramik radyografi değerlendirildi. Ektopik sürme olgularında en sık hangi dişlerin ektopik olarak sürdüğü, hangi cinsiyet ve yaşta daha sık görüldüğü, simetrik dağılım sergileyip sergilemediği, ektopik sürmenin şiddeti değerlendirildi. Asimetrik ektopik sürme vakalarında, hem ektopik sürmüş, hem de normal sürmüş dişlerde DBM'lerinin diş gelişim aşamaları Nolla yöntemine göre karşılaştırıldı. Ayrıca alt çenedeki ektopik erüpsiyon olgularında diş gelişimi Cameriere metodu ile de karşılaştırmalı olarak değerlendirildi. Verilerin istatistiksel analizinde ki-kare testi ve t-testi kullanıldı. Bulgular: Toplam 315 olguda ektopik erüpsiyon tespit edildi ve DBM'lerde ektopik erüpsiyon görülme sıklığı %2,05 olarak hesaplandı. Ektopik erüpsiyon olgularının %54,8'i erkek ve %45,2'si kız olarak belirlendi ve cinsiyete göre fark gözlenmedi (p>0,05). Bu olgularda toplam 429 DBM'nin ektopik erüpsiyonda sürdüğü gözlendi. Ektopik erüpsiyondaki DBM'lerden 370 tanesi üst çenede (83,0%) ve 59 (17%) tanesi alt çenede yer almaktaydı ve çeneler arasındaki dağılımın istatistiksel olarak anlamlı olduğu belirlendi (p<0,05). Diş gelişimi değerlendirildiğinde, toplam 205 adet DBM'nin asimetrik olarak ektopik erüspsiyon sergilediği, etkilenen ve etkilenmeyen yarım çenelerde en fazla görülen diş gelişim skorunun Nolla 7 olduğu belirlendi. Ektopik erüpsiyon bölgesindeki DBM'lerin diş gelişim skor dağlımlarının karşılaştırılan dişlerden farklı olduğu belirlendi (p<0,05). Ayrıca alt çenedeki DBM'lerin Cameriere ölçüm sonuçları karşılaştırıldığında ektopik erüpsiyondaki DBM'lerin ölçüm değerlerinin etkilenmeyen tarafa göre daha yüksek olduğu belirlendi (p<0,05) Sonuç: Ektopik erüpsiyondaki DBM'lerin diş gelişimlerinin etkilenmeyen taraftaki karşıt dişlerden daha geride olduğu gözlendi. Diş gelişimi geri olan DBM'lerin ektopik olarak sürebileceği ya da ektopik erüpsiyonunun diş gelişiminde gecikmeye yol açabileceği düşünülmektedir.

Aim: To radiographically evaluate the relationship between ectopic eruption of permanent first molars and the level of tooth development of these teeth radiographically. Methods: In the present study a total of panoramic radiographs of 15.332 patients (6116 females, 9216 males) aged from 5 to 9 years old who attended Ondokuz Mayis University, Faculty of Dentistry was evaluated. In cases of ectopic eruption, which teeth erupted ectopically most frequently, in which gender and age it was more common, whether it exhibited symmetrical distribution, and the severity of ectopic eruption were recorded. In asymmetric ectopic eruption cases tooth development stages of both ectopicaly erupted and normally erupted teeth were compared according to the Nolla method. In addition, tooth development in cases of ectopic eruption in the mandible was also evaluated comparatively with the Cameriere method. Chi-square test and t-tests were used in the statistical analysis of the data. Results: A total of 315 cases were diagnosed with ectopic eruption, and frequency of ectopic eruption was calculated as 2,05%. Of these 54.8% of ectopic eruption cases are belong to male and 45.2% are female The difference between genders was not statistically significant (p>0,05). A total of 429 ectopic PFMs were detected and 83% (370) of them were located in maxilla and 17% (59) of them were in the mandible. The difference between the jaws was statistically significant (p<0,05). When dental development was evaluated, it was determined that a total of 205 PFMs exhibited asymmetric ectopic eruption, and the most common development score according to the Nolla method is 7 for affected and unaffected teeth. The tooth development score distributions of the DBMs in the ectopic eruption area were found to be different from the compared teeth (p<0,05). İn addition, when the Cameriere measurment resuls of the PFMs in the mandible were compared, it was determined that the measurment values of the PFMs in the ectopic eruption were higher than the unaffected side (p<0,05). Conclusion: It was observed that the tooth development of DBMs with ectopic eruption was delayed the opposing teeth on the unaffected side. It was thought that DBMs with delayed tooth development may erupt ectopically or ectopic eruption may lead to delayed tooth development.
