INTRODUCTION: Fusion is a dental anomaly which arises through the union of two adjacent teeth or the union of a normal and a supernumerary tooth in embryological stage.This report describes a case of unilateral fusion of the primary mandibular lateral incisor and canine and aims to evaluate any associated pathology.

CASE REPORT: In the clinical examination of an eight-year-old girl visited our clinic for a routine dental examination, a wide crown separated by a labi- o-lingual groove was observed in the mandibular left deciduous lateral-canine region. Clinical and radiographic evaluation revealed that teeth 72 and 73 were fused, the permanent right lateral tooth had erupted, and the left lateral tooth was congenitally missing. The management of the case, initially a fissure sealant was applied because the labio-lingual groove on the fused tooth had formed a retentive area. Secondly, the root resorption level of the fused tooth, located in the eruption path of the permanent canine, was assessed using the resorption level of the symmetrical primary canine as a reference, and parallel resorption was observed. Finally, follow-up appointments were scheduled for two weeks, three months, six months and one year to monitor preventive practices, root resorption level of the fusion tooth and congenital missing tooth.

CONCLUSIONS: This case revealed a unilateral fusion anomaly involving the lower primary lateral incisor and primary canine, along with the absence of the permanent lower lateral incisor. This demonstrates the importance of considering associated clinical conditions when fusion is observed in primary teeth.

GİRİŞ: Füzyon, iki komşu dişin veya normal diş ile sürnümerer dişin embriyolojik safhada kaynaşmasıyla meydana gelen bir dental anomalidir. Bu rapor, süt mandibular lateral kesici diş ve kanin dişin tek taraflı füzyonu olan bir vakayı tanımlamakta ve ilişkili herhangi bir patolojiyi değerlendirmeyi amaçlamaktadır.

OLGU RAPORU: Rutin dental muayene için kliniğimize başvuran 8 yaşındaki kız çocuğun yapılan klinik muayenesinde mandibular sol süt la- teral-kanin diş bölgesinde labio-lingual oluk ile ayrılmış geniş kron gözlendi. Klinik ve radyografik değerlendirme sonucu 72 ve 73 nu- maralı dişlerin füzyona uğradığı, daimi sağ lateral dişin sürdüğü ve sol lateral dişin ise konjenital olarak eksik olduğu tespit edildi. Olgunun yönetiminde ilk olarak hastanın füzyon dişinde bulunan labio-lingual oluğun retantif alan oluşturması nedeniyle fissür örtücü uygulandı. İkinci olarak daimi kanin dişin sürme yolunda bulunan füzyon dişin kök rezorpsiyon seviyesi simetrik süt kanin dişin rezorpsiyon seviyesi referans alınarak değerlendirildi ve paralel rezorpsiyon gözlendi. Son olarak koruyucu uygulamalar, füzyon dişin kök rezorpsiyon seviyesi ve konjenital diş eksikliği durumlarının takibi için iki hafta, üç ay, altı ay ve bir yıllık takip randevuları planlandı.

SONUÇLAR: Bu olgu alt süt lateral kesici diş ve süt kanin dişin tek taraflı füzyon anomalisi ile beraberinde görülen alt daimi lateral diş eksikliğini ortaya koymuş ve süt dişlerinde füzyon görüldüğünde ilişkili klinik durumların göz önüne alınmasının yararlı olduğunu göstermiştir.
