“…The prevalence of fused teeth in the primary dentition is approximately 1%. 13 When fusion occurs in the primary dentition, especially in the case of the fusion between the deciduous lateral incisor and canine, 74% of the successional lateral incisors are absent. 14 In our case, the fused deciduous lateral incisor and canine were found in the retained primary dentition, although, unusually, the permanent successors were also present.…”

Cleidocranial dysplasia (CCD) is a rare congenital disorder, typically characterized by persistently open skull sutures, aplastic or hypoplastic clavicles, and supernumerary teeth. Mutations in the gene encoding the runt-related transcription factor 2 (RUNX2) protein are responsible for approximately two thirds of CCD patients. We report a 20-year-old CCD patient presenting not only with typical skeletal changes, but also complex dental anomalies. A previously undiagnosed odontoma, 14 supernumerary teeth, a cystic lesion, and previously unreported fused primary teeth were discovered on cone-beam computed tomography (CBCT) scans. Mutation analysis identified the causal c.578G>A (p.R193Q) mutation in the RUNX2 gene. At 20 years of age, the patient had already missed the optimal period for dental intervention. This report describes the complex dental anomalies in a belatedly diagnosed CCD patient, and emphasizes the significance of CBCT assessment for the detection of dental anomalies and the importance of early treatment to achieve good outcomes.

“… 1 This malformation is also related to complex tooth morphology and pulpal anatomy, and the tooth position can additionally cause difficulty in rubber dam placement. 4 For these reasons, surgical therapy may be preferable to endodontic treatment in most cases. 1 4 Fused teeth may also have deep fissures or grooves that may lead to caries and periodontal diseases, such as pericoronitis and paradental cysts.…”

“…3 It is usually seen in the maxillary arch, and rarely occurs in the posterior mandible. 4 The etiology of fusion is still unclear; however, it has been suggested that the pressure or physical forces that provide close contact between two adjacent dental follicles may cause the follicles to fuse before calcification. 5 The main periodontal problem in cases of fusion is the presence of deep fissures or grooves that extend subgingivally on the union between the teeth involved.…”

Role of cone-beam computed tomography in the evaluation of a paradental cyst related to the fusion of a wisdom tooth with a paramolar: A rare case report

et al. 2016

View full text Add to dashboard Cite

Fusion is an abnormality of tooth development defined as the union of two developing dental germs, resulting in a single large dental structure. This irregular tooth morphology is associated with a high predisposition to dental caries and periodontal diseases. As a result of recurring inflammatory periodontal processes, disorders such as periodontal pocket, pericoronitis, and paradental cysts may develop. A rare mandibular anatomic variation is the retromolar canal, which is very significant for surgical procedures. The fusion of a paramolar and mandibular third molar associated with a paradental cyst co-occurring with the presence of a retromolar canal is rare, and the aim of the present study is to describe the evaluation of this anatomical configuration using cone-beam computed tomography.
