Abstract

Objective: Fusion is a developmental dental anomaly resulting from the union of two adjacent teeth. The etiology of fusion is not definitively known. This developmental anomaly can lead to functional and aesthetic problems in individuals' lives. Furthermore, in the majority of cases with fusion in primary teeth, a lack of permanent teeth is identified. The aim of this case report is to present three patients diagnosed with fusion in primary dentition.
Case Report: The first patient, a 4-year-old child, presented to our clinic for routine examination. Clinical and radiological assessments revealed fusion in the mandibular anterior region, as well as the absence of one primary lateral tooth and a permanent lateral tooth. The second patient, a 6-year-old, visited our clinic due to dental pain. Oral and radiographic findings indicated fusion in the mandibular anterior region and the absence of a lateral permanent tooth. The last patient was a 5-year-old who presented with dental pain. Radiographic findings showed fusion in the mandibular region. The guardians of the patients were informed about the relevant anomalies. Written and verbal consent was obtained from the legal guardians prior to the necessary treatments. The patients whose treatments were completed are being monitored regularly for potential complications arising from their anomalies.
Conclusion: Fusion is one of the rare dental anomalies. Clinical and radiographic observations are essential for the diagnosis of fusion. In certain situations, a multidisciplinary treatment approach is required. Early diagnosis of this anomaly can help eliminate potential complications while reducing the need for treatment.

Abstract

Amaç: Füzyon, birbiriyle komşu olan iki dişin birleşimden kaynaklı gelişimsel bir dental anomalidir. Füzyonun etyolojisi kesin bir şekilde bilinmemektedir. Bu gelişimsel anomali bireylerin yaşamında fonksiyonel ve estetik açıdan problemlere sebep olabilir. Bununla birlikte, süt dişlerinde füzyon görülen vakaların çoğunluğunda sürekli diş eksikliği tespit edilmektedir. Bu olgu raporunun amacı süt dentisyon füzyon tespit edilmiş üç hastanın sunumu amaçlanmıştır.
Olgu sunumu: 4 yaşında kontrol amacıyla kliniğimize başvurmuş hastanın klinik ve radyolojik incelemelerinde mandibular anterior bölgede füzyon, tek süt lateral ve daimi lateral dişlerin eksik olduğu saptanmıştır. İkinci hasta ise; 6 yaşında olup, diş ağrısı dolayısıyla kliniğimize gelmiştir. Hastanın oral ve radyografik bulgularında mandibular anteriorda füzyon ve lateral daimi diş eksikliği saptanmıştır. Son hastamız ise; 5 yaşında olup diş ağrısı kaynaklı kliniğe başvuruda bulunmuştur. Hastanın oral radyolojik bulgularında mandibular bölgedeki dişlerinde füzyon olgusuna rastlanılmıştır. Hastaların velileri ilgili anomali hakkında bilgilendirilmiştir. Gerekli tedaviler öncesinde yasal vasilerinden yazılı ve sözlü onamları alınmıştır. Tedavileri tamamlanan hastaların anomali kaynakları olası durumlar için düzenli takipleri gerçekleştirilmektedir.
Sonuç: Füzyon, ender görülen dental anomalileri arasındadır. Füzyon teşhisinde klinik ve radyografik gözlem gereklidir. Belirli durumlarda multidisipliner tedavi gereksinimi söz konusudur. Bu anomalinin erken teşhisi olası komplikasyonları elimine ederken, tedavi gereksinimini de azaltacaktır.
