Ternion Cusp: An Unusual Variant of Talon\'s Cusp: A Case Report

Abstract

A bstract Background Teeth are hard mineralized anatomical components of the dentofacial skeleton that are developed during the gestation period by odontogenesis. This dental development comprises five stages viz. initiation, proliferation, histodifferentiation, morphodifferentiation, and apposition. Excitation to the dental organ during morphodifferentiation is responsible for the formation of a talon cusp, which manifests as a cusp-like structure of hard tissue projecting from the cingulum to a varying measurable length toward the incisal edge of maxillary and mandibular anterior teeth. Various literature has reported that it comprises enamel, dentine, and an inconsistent amount of pulp tissue. Old literature suggests its occurrence in primary and permanent teeth and mostly on the palatal aspect of teeth as one cusp; therefore, known as a talon cusp (eagle's talon). Case description An exceptional case of three cusped structures projecting from the palatal side of a maxillary central incisor is thus reported. The rare occurrence of an atypical talon cusp with three well-defined mamelon-like cusps on the palatal surface of the permanent maxillary central incisor is coined as ternion cusp, meaning ”three” by authors. Its occurrence is repercussed as attrition of the teeth in the opposite arch. Selective or retruded contact position (RCP) was done, followed by topical fluoride application was rendered. Conclusion Managing and treating these exceptional cusps depends upon their size, present complications, and patient compliance. How to cite this article Sharma V, Mohapatra A, Bagchi A.

Concurrent Occurrence of Ear Tag With Posterior Talon Cusp, Fissured Tongue, and Ankyloglossia: A Case Report

“…Ankyloglossia or tongue-tie is a short lingual frenum attached to the ventral surface near the tip of the tongue and results in difficulty in the pronunciation of certain words, such as the combination of letters: t, r, l, d, n, z, sh, and th [11]. The treatment of ankyloglossia includes frenotomy under local anesthesia or frenuloplasty under general anesthesia [11]. Myofunctional therapy has promising effectiveness in treating ankyloglossia [11].…”

“…The treatment of ankyloglossia includes frenotomy under local anesthesia or frenuloplasty under general anesthesia [11]. Myofunctional therapy has promising effectiveness in treating ankyloglossia [11]. Ankyloglossia can also be found in many congenital syndromes, such as Beckwith-Wiedemann, Simosa, Ehlers-Danlos, Simpson-Golabi-Behmel, oral-facial digital syndromes, Opitz, and Xlinked cleft palate, and in newborns from cocaine-addicted mothers [11].…”

Lingual laser frenotomy reduces complications such as less bleeding, rapid healing, intraoperative pain, and complications [12].…”
