Concrescence is a developmental anomaly of the teeth, wherein roots fuse, with no evidence of periodontal space between two or more normal teeth below the cementoenamel junction. It is caused by
a confluence of the cemental surfaces
[1–3]. The confluence may occur in between normal tooth and supernumerary tooth [2].
Which part of the tooth is fused in concrescence?
And when the cementum of one tooth cements with the cementum of another tooth, concrescence occurs. That phenomenon means the two teeth are connected at the roots, which is pretty unusual. Even more uncommon, sometimes the next tooth layer,
dentin
, fuses with another’s tooth’s dentin at the root level.
What is dental Concrescence?
Concrescence is
a developmental anomaly of dental hard tissues
. It is a condition showing union of adjacent teeth by cementum. The concrescence leads to a loss of gingival architecture leading to the development of funnels, which may cause plaque accumulation thus, resulting in periodontal tissue destruction.
What is twinning in dentistry?
Twinning is referred to
the development of two separate teeth that arose from the complete separation of one tooth bud
. To the best of our knowledge very few cases of twinning in primary or permanent dentition have been previously reported.
What is the difference between fusion and gemination?
Gemination and fusion are the most commonly encountered anomalies in dental practice, and distinction between the two is
always challenging
. Fusion is when two tooth buds fuse to make a large tooth. Gemination, also called double tooth is an anomaly exhibiting two joined crowns and usually a single root.
What is Oligodontia?
Oligodontia is
a rare genetic disorder which represents the congenital absence of more than six teeth in primary, permanent
or both dentitions. It is usually a part of a syndrome and seldom occurs as an isolated entity.
Which is the 3rd most common missing tooth in Hypodontia?
Dental Anomalies
The most commonly missing teeth are
third molars
, followed by mandibular second premolars (Fig. 31-9) and maxillary lateral and mandibular central incisors.
What is a fused tooth called?
Fusion occurs when
two teeth join
into one and looks similar to gemination. However, if the fused teeth are counted as one tooth, the child will be missing a tooth. Gemination and fusion are most common in the upper front teeth, but they can also occur in the lower teeth.
What structure is formed in the crown first?
Dentin formation
, known as dentinogenesis, is the first identifiable feature in the crown stage of tooth development. The formation of dentin must always occur before the formation of enamel.
How does syphilis affect the 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.
Which tooth is the most common supernumerary tooth?
The most common supernumerary tooth is
a mesiodens
, which is a malformed, peg-like tooth that occurs between the maxillary central incisors. Fourth and fifth molars that form behind the third molars are another kind of supernumerary teeth.
What is enamel dysplasia?
Enamel dysplasia is
a condition that affects the normal levels of one’s tooth enamel
. A form of exceptionally hard tissue, enamel acts as a protective outer shell to cover the part of the tooth that contains the sensitive pulp, dentin and cementum tissues.
What is the most common type of material that an implant is made out of?
Titanium dental
implant materials – Made from metal, Titanium is regarded as the most common type of dental implant materials. Its great characteristic was discovered in 1950. During this time, findings show that implants made from titanium metal allow the bone to grow aright.
Can two teeth grow together?
Tooth fusion
is what happens when two separate tooth buds grow together and form into one tooth that is literally fused together. Fused teeth may have two separate tooth buds, and even their own pulp chambers and canals, but upon extraction or falling out, they will still be fused together as one solid tooth.
How rare is a double tooth?
Although the prevalence rate is variable in individual reports, the overall prevalence appears to be approximately 0.5% in the deciduous teeth and
0.1% in the permanent dentition
.
What is the meaning of Gemination?
noun.
the act or state of being doubled
or paired. the doubling of a consonant. the immediate repetition of a word, phrase, or clause for rhetorical effect.
