What stage does dens in dente occur?
Dens invaginatus, or dens in dente (which translates to “tooth within a tooth”), is a dental anomaly. This condition occurs when the tooth’s enamel (the outer, visible layer of the tooth) folds into the dentin (the hard tissue beneath the enamel) during tooth development.
Where is dens in dente most common?
Dens in dente, also known as dens invaginatus or dilated composite odontome is a rare developmental tooth anomly characterized by invagination of the enamel organ into the dental papilla. The frequency of dens in dente is more common in permanent maxillary lateral Incisors[1].
How common is dens in dente?
Dens invaginatus (DI), also known as tooth within a tooth, is a rare dental malformation where there is an infolding of enamel into dentine. The prevalence of condition is 0.3 – 10%, affecting more males than females.
What is a Palatogingival groove?
Palatogingival groove or radicular lingual groove (RLG) is a developmental anomaly that occurs as developmental infoldings of the inner enamel epithelium and Hertwig’s epithelial root sheath (HERS), involving primarily maxillary lateral incisors.
What is the cause of dens Invaginatus?
Dens invaginatus occurs as a result of the invagination of the enamel organ. These cases may present difficulties with respect to its diagnosis and treatment because of canal morphology. It frequently leads to caries, pulpal, and periodontal involvement with necrosis and loss of attachment.
What is cusp of Carabelli?
The Cusp of Carabelli is a characteristic morphological trait often seen on the palatal surface of the mesiopalatal cusp of maxillary permanent molars and maxillary second deciduous molars [2].
How rare is a talon cusp?
Talon cusp, also known as eagle’s talon, is a manifestation of dens evaginatus in the anterior teeth. The incidence has been found to range from less than 1% to 6% of the population, in which 55% occur on the permanent maxillary central incisor, and 33% occur on the permanent maxillary lateral incisor.
What is a developmental groove?
n. One of the fine lines found in the enamel of a tooth that mark the junction of the lobes of the crown in its development.
What are Hutchinson’s teeth?
Hutchinson teeth is a sign of congenital syphilis, which occurs when a pregnant mother transmits syphilis to her child in utero or at birth. The condition is noticeable when a child’s permanent teeth come in. The incisors and molars take on a triangular or peglike appearance.
What is “dens in dente?
“Dens in dente” is a developmental malformation incident due to the in folding of enamel and dentin or an accentuation of the lingual pit of an incisor before calcification sets in.
What is a dens dens invaginatus?
Dens invaginatus, or dens in dente (which translates to “tooth within a tooth”), is a dental anomaly. This condition occurs when the tooth’s enamel (the outer, visible layer of the tooth) folds into the dentin (the hard tissue beneath the enamel) during tooth development. This creates what looks like a small tooth within an existing tooth.
Which incisors are most affected by dens in dente?
The maxillary lateral incisors (the pair of teeth on either side of the two front teeth) are most commonly affected by dens in dente, followed by the maxillary central incisors (the two front teeth). Researchers still aren’t sure what causes this anomaly.
What are the treatments for dens in dente?
Treatment for dens in dente depends on how far the crevice extends into the interior of the tooth. In minor cases, sealing the crevice with composite resin or sealant may be all that’s required, explains the case report in the Journal of Conservative Dentistry.
