Surgical management of fused 3rd and 4th molars. A case report

“…This paper reports a specific case of changes in shape and number, namely fusion and supernumerary teeth. Fusion occurs most frequently in deciduous dentition (0.5-12.5%) (Cai, et al, 2019;Açıkel, et al, 2018;Steinbock, et al, 2014;Prakash, et al, 2012;Rosas, et al, 2004), predominantly in incisors and canines (Goh & Tse, 2020;Açıkel, et al, 2018;Goswami & Jangra, 2017;Steinbock, et al, 2014;Rosas, et al, 2004;Delany & Goldblatt, 1981), without affecting the total number of teeth in the arch (Liang, et al, 2012). It may be related to syndromes such as osteopetrosis, chondroectodermal dysplasia, achondroplasia, among others and may occur due to interference from environmental factors such as exposure of the fetus to alcohol, hypervitaminosis or thalidomide use during pregnancy (Bamgbose, et al, 2019;Liang, et al, 2012).…”

“…When fusion occurs in deciduous anterior teeth, extraction can be done, depending on the case, it is necessary to use space maintainer or dental plastic (Steinbock, et al, 2014). In anterior permanents, the bone tissue is mature, thus, the extraction and installation of implants or orthodontic space correction may be performed (Goh & Tse, 2020;Kim, et al, 2019;Rosas, et al, 2004;Velasco, et al, 1997); Root canal treatment can also be followed by dental plastic surgery (Vinothkumar, et al, 2017;Steinbock, et al, 2014).…”

All We Need to Know about Normal and Abnormal Human Teeth

“…Clinically, a fused tooth looks like a larger tooth and sometimes is mixed with gemination because All We Need to Know about Normal and Abnormal Human Teeth DOI: http://dx.doi.org/10.5772/intechopen.109738 both types of teeth have an incisure on the middle of the crown, but radiographic difference is much clearer. Fused teeth have separate pulp chambers for each tooth, while gemination has one larger pulp chamber and there are two roots or two canals in a single root [42]. The degree of union may be total or partial and often presents with a coronal incisure.…”

Management of a supernumerary tooth fused to the labial surface of a permanent maxillary central incisor

“…Some others believe that fusion arises from the persistence of the interdental lamina between the two buds during embryological development 8 . Other causes include genetics, racial predisposition, or even trauma during tooth development 9,10 . Based on the studies of case reports, fusion can be seen in Robinow syndrome 11 and some rare diseases such as congenital erythropoietic porphyria, hypophosphatasia, Marfan syndrome, and Peutz–Jeghers syndrome 12 .…”
