“…The calcified tissue gradually became obvious after eruption and CBCT was diagnosed as a fused tooth. There have been many reports on the effectiveness of CBCT [24,28,30,35,36,39,42,46]. However, in the present case, the tooth eruption was delayed compared with the left side in the alveolar bone before CBCT was taken.…”

Tooth fusion is a dental anomaly with a prevalence of 0.1% in permanent dentition. The aim of this paper is to present the occurrence, region of fusion, and prognosis of fused tooth which is a very rare case in the literature. The authors present a very rare case with a maxillary right lateral incisor fused to a supernumerary tooth on the palatal side. The eruption was delayed, but eruption occurred naturally at 9 years and 6 months. However, cone-beam computed tomography at 11 years and 6 months revealed it was diagnosed as a fused tooth. The authors undertook a literature review over the past 10 years and found 30 articles about fused teeth between permanent teeth and supernumerary teeth. It was more common in males than females and there were no differences depending on the occurrence. Mesiodistal fusion was more common in the incisor region, while labiopalatal fusion was more common in the molar region. Most cases required dental treatment with a surgical approach, root canal treatment, or orthodontic treatment. The present study highlights the importance of long-term follow-up and suggests the region of fusion and prognosis of the fused tooth may vary depending on the occurrence.

“…A supernumerary cusp is an abnormality of the tooth shape. A supernumerary cusp usually refers to an accessory cusp on the buccal or lingual surface of a normal crown such as a talon cusp, central cusp or Carabelli cusp [ 6 , 12 ]. In the clinic, the Carabelli cusp is frequently observed on the palatal surface of the mesiopalatal cusp of the maxillary permanent molars and maxillary second deciduous molars [ 13 ].…”

Background A protostylid is a relatively rare dental developmental aberration characterized as an extra cusp located on the mesial half of the buccal surface of the molars. A protostylid is rarely to be reported due to its low rate of occurrence. This case report describes a patient referred for endodontic treatment due to the presence of a protostylid on the buccal surface of the maxillary first molar that induced apical periodontitis. Case presentation A 53-year-old female reported a 3-month history of pain of chewing with her upper left posterior teeth over 3 months. In the clinical examination, an abraded anomalous cusp-like structure was found on the buccal surface of tooth 26, Cone beam computed tomography (CBCT) revealed a supernumerary cusp with an intact root canal inside, which was fused with the mesiobuccal (MB) root canal in the middle of the root. In addition, extensive periapical radiolucency was observed around tooth 26. The tooth was diagnosed as apical periodontitis, and endodontic treatment was performed. The initial lesion in tooth 26 gradually healed over 1 year of observation. Conclusions To our knowledge, this case is the first to describe the endodontic management of a maxillary first molar with a protostylid and advances our understanding of supernumerary cusps. This case provides a reference for the treatment of protostylid.

“…15 In single cases, cone-beam computed tomography (CBCT) is used for the diagnosis of double teeth and treatment planning. [4][5][6]9,15,16 For example, Buchanan et al concluded in a case of a 12-year-old girl with a double gemination that the use of three-dimensional (3D) imaging greatly aids treatment planning and communication with the patient in such uncommon and unusual cases. 4 Double teeth are not an exact dental diagnosis, but are often used as a catch-all term when the diagnosis is unclear.…”

Double teeth, like fusions and geminations, are rare disorders of tooth development. In this short case presentation, we describe the unique appearance of a fully erupted mandibular wisdom tooth in a 72-year-old patient whose tooth exhibited gemination. This was possible because tooth 46 had to be removed from the patient at the age of 20 and the missing molar was not replaced. This geminated tooth of 48 had been in function for almost 50 years and finally had to be removed due to a periodontal inflammation. To the best of our knowledge, this is the first case presented of this dental anomaly for a fully erupted lower wisdom tooth.

Precision diagnosis and antidiastole on supernumerary cusp of tooth by CBCT

Abstract: Supernumerary cusp on the bucca of left maxillary second molar is a rare phenomenon, which is difficult to be differentiated from other tooth deformities. CBCT can improve accuracy of diagnosis.
