Braket Yuvası Boyutu 0,018-inç ve 0,022 inç ile Ortodontik Tedavi Sırasında Apikal Kök Resorpsiyonunun Radyografik Karşılaştırılması

Amaç: Ortodontik kaynaklı apikal kök rezorpsiyonu, vakaların% 90'ından fazlasında görülen ortodontik tedavilerin kaçınılmaz bir yan etkisidir. Ortodontik Kaynaklı İnflamatuvar Kök Rezorpsiyonu, bireysel biyolojik varyasyonlar ve mekanik uyaranların bir sonucu olarak ortaya çıkar. Yöntem: Bu çalışmada, iki farklı büyüklükte slot (0.018 inç ve 0.022 inç) ve aynı tel çapı ile sabit ortodontik tedavi (düz telli sistem) alan hastalarda kök rezorpsiyonunun kapsamı karşılaştırılmıştır. Bu amaçla, tedavi öncesi ve sonrası 720 dişi incelemek için panoramik radyografiler kullanıldı. Kök rezorpsiyonunu değerlendirmek için ilk önce Malgren sınıflamasına, diğeri ise Crown-Root oranına (C / R) dayanan iki farklı yaklaşım kullanılmıştır. Bulgular: Öncelikle, 0.018 inçlik yuva destekleri ile tedavi edilen hastalar için ortalama tedavi süresi 26 aydı ve 0,022 inçlik yuva destekleriyle tedavi edilenler için 25 ay idi. Bu çalışmada araştırılan iki grupta anlamlı bir fark bulunmamıştır (p değeri = 0.684). Yuva büyüklüğünün kök rezorpsiyonu üzerinde bir etkisi yoktur ve etkili olabilecek yuvaların verimliliği de dahil olmak üzere başka bazı özellikler vardır. Sonuç: Bu çalışmada incelenen iki grupta anlamlı bir fark bulunmadığı için, slot büyüklüğünün kök rezorpsiyonu üzerinde bir etkisi olmadığı ve etkili olabilecek slotların etkinlik seviyesi de dahil olmak üzere başka bazı özelliklerin olduğu tartışılabilir. Önceki çalışmalarda belirtildiği gibi, 0,022 inçlik yuva destekleri kök rezorpsiyonu üzerinde daha fazla etkiye sahip olabilir. Apex şeklinin bu konuda hiçbir etkisi yoktur.

Radiographic Comparison of Apical Root Resorption During Orthodontic Treatment with Bracket Slot Size 0,018-inch and 0,022-inch

Objectives: Orthodontic induced apical root resorption is an unavoidable sideeffect of orthodontic treatments which is seen in more than 90% of the cases.Orthodontic Induced Inflammatory Root Resorption (OIIRR) occurs as a result ofindividual biologic variations and mechanical stimuli effects.Material and method: In this study the extent of root resorption is compared inpatients who have received fixed orthodontic treatment (by straight wiresystem), with two different sizes of slots (0.018 inch and 0.022 inch) and thesame wire diameter. For this purpose, panoramic radiographs were used toexamine some 720 teeth before and after the treatment. Two differentapproaches were used to evaluate the root resorption, first based on Malgrenclassification and the other based on Crown-Root ratio (C/R).Result: Average duration of treatment for patients treated by 0.018-inch slotbrackets was 26 months and for those who were treated by 0.022-inch slotbrackets it was 25 months. No significant difference was found in the two groupsexplored in this study (p-value = 0.684). Slot size has no effect on root resorptionand there are some other features including the efficiency of the slots whichmight be influential.Conclusion: As no significant difference was found in the two groups explored inthis study, it could be argued that slot size has no effect on root resorption andthere are some other features including the efficiency level of the slots whichmight be influential. As previous studies indicate, 0.022-inch slot brackets couldhave more influence on root resorption. Apex shape has no effect in that regard.
