Concrescence of the right maxillary second and third molars: A case report

Abstract

Herein, we reported a rare case of concrescence of #17 and #18, including the clinical and imaging findings. After extracting the concrescence, the fistula on #17 gradually disappeared. In addition, we analyzed the histological etiology and clinical diagnosis and treatment of concrescence from the sight of periodontal functional stimulation.

Gemination of an Erupted Mandibular Third Molar: A Short Presentation of an Exceptionally Rare Clinical Occurrence

“…Concrescence is often found in maxillary molars. 7 Concrescence can be further divided into an acquired and true form with regard to its possible etiology. The true concrescence occurs between two developing teeth, whereas the acquired form develops between two fully formed teeth.…”

“…The true concrescence occurs between two developing teeth, whereas the acquired form develops between two fully formed teeth. 7…”

“…[3][4][5][6] Concrescence as dental twin anomaly consists only of a union between two or more teeth over the cementum in either deciduous or permanent dentition. 1,6,7 This means that only the roots of two adjacent teeth are fused. Concrescence is often found in maxillary molars.…”

“…The true concrescence occurs between two developing teeth, whereas the acquired form develops between two fully formed teeth. 7 Fusion (also referred to synodontia or false gemination) is defined as a union between the dentin of two or more separately developing teeth. The fusion may be total or partial.…”
