Abstract

In the present retrospective study, it was aimed to analyze the physiological effects of impacted mesiodens on adjacent teeth with dental and chronological age determination in cone beam computed tomography (CBCT). In the study, 68 CBCT images were examined. Two groups were formed, including 34 individuals with mesiodens (mesiodens group) and 34 without mesiodens (control group).Dental age and chronological age were compared in both groups. Demirjian's method was utilized to determine the dental age. The position and location of mesiodens were categorized. Statistical analysis was performed withSPSS software version 18.0(Chicago, IL, USA). Median diastema was seen in 16 cases (47.10%) in the mesiodens group. The mesiodens was most commonly impacted in the palatal (76.50%, n=26) and vertical (n= 19, 55.90%) position. There were significant differences between the incisor tooth development scores of the groups (p= 0.047 and p= 0.030, respectively). While the prevalence of H score of bilateral incisors in the control group (88.20% for both incisors) was higher than that of the mesiodens group (58.20% for both incisors), the G score was higher in the mesiodens group (20.60% and 23.50%) than in the control group (2.90% for both teeth). Mesiodens can delay root development of adjacent teeth.For this reason, extraction of these teeth may be considered in the early period to avoid affecting adjacent teeth and anatomical structures. It may also cause erroneous calculations in dental age determination. This situation should be taken into account in terms of forensic dentistry.

GÖMÜLÜ MEZİODENSLERİN KOMŞU DİŞLERİN GELİŞİMİ ÜZERİNDEKİ FİZYOLOJİK ETKİLERİ

Abstract

Bu retrospektif çalışmada, Konik Işınlı Bilgisayarlı Tomografide (KIBT) gömülü meziodenslerin komşu dişler üzerindeki fizyolojik etkilerinin dental vekronolojik yaştayini ile analiz edilmesi amaçlanmıştır. Çalışmada 68 KIBT görüntüsü incelendi. 34 meziodensi olan (meziodens grubu) ve 34 meziodensi olmayan birey (control grubu) olmak üzere iki grup oluşturuldu. Diş yaşı ve kronolojik yaş her iki grupta karşılaştırıldı. Diş yaşını belirlemek için Demirjian yöntemi kullanıldı. Meziodenslerin pozisyonu ve konumu categorize edildi. İstatistiksel analiz SPSS yazılımı sürüm 18.0 (Chicago, IL, ABD) ile yapıldı. Meziodens grubunda 16 (%47.10) olguda orta hatta diastema görüldü. Meziodens en sık palatinal konumda (%76.50, n=26) ve vertikal (n= 19, %55.90) pozisyonda görüldü. Grupların kesici diş gelişim skorları arasında anlamlı fark vardı (sırasıyla p= 0.047 ve p= 0.030). Kontrol grubunda bilateral kesici dişlerin H skoru prevelansı (her iki kesici dişi çin %88.20) meziodens grubundan (her iki kesici diş için %58.20) daha yüksek iken, G skoru meziodens grubunda control grubuna göre (%20.60 ve %23.50) daha yüksekti (Her iki diş için %2.90). Meziodens komşu dişlerin kök gelişimini geciktirebilir. Bu nedenle komşu dişlerin ve anatomic yapıların etkilenmemesi için erken dönemde bu dişlerin çekimi düşünülebilir. Diş yaşı tespitinde de hatalı hesaplamalara neden olabilir. Bu durum adli diş hekimliği açısından dikkate alınmalıdır.
