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 the cause of concrescence?

Cause. This condition arises as the result of traumatic injury or overcrowding of teeth. True concrescence occurs during root formation phase, whereas acquired concrescence occurs after the radicular phase of development is complete.

What is dental dilaceration?

According to the glossary of dental terms,4 dilaceration is defined as the deformity of a tooth due to a disturbance between the unmineralized and mineralized portions of the developing tooth germ.

What is fusion gemination and concrescence?

Concrescence involves fusion of cementum only. Twinning is more complete than gemination and results in the formation of two separate teeth from one tooth bud (one extra tooth in the arch). In gemination, separation is attempted, but the two teeth share the same root canal.

What causes dilaceration?

Two possible causes of dilaceration are trauma and developmental disturbances, and it has also been proposed that it might be associated with some developmental syndromes. Dilaceration can be seen in both the permanent and deciduous dentitions, and it is more commonly found in posterior teeth and in the maxilla.

What is tooth Gemination?

Gemination and fusion are anomalies in size, shape and structure of teeth. Gemination more frequently affects the primary teeth, but it may occur in permanent dentitions, usually in the incisor region. Geminated teeth are typically disfigured in appearance due to irregularities of the enamel.

What is the second tooth in Hypodontia?

It rarely occurs in primary teeth (also known as deciduous, milk, first and baby teeth) and the most commonly affected are the adult second premolars and the upper lateral incisors.

What is the difference between Gemination and fusion?

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 causes tooth Gemination?

Gemination is an anomaly caused by a single tooth germ that attempted to divide during its development, resulting in a bifid crown. They are found more frequently in the primary than in the permanent dentition unilaterally, but bilateral gemination is very rare.

How do you diagnose Dilaceration?

Dilaceration can be diagnosed with a simple radiograph of the affected teeth. However, if the bends are more lingual or facially present, more advance imaging techniques may be necessary. In some cases a cone-bean CT scan may be useful to create a three dimensional view.

How common is Dilaceration?

Results: Root dilaceration was detected in 0.3% of teeth and 7.2% of patients. It was distributed equally between the maxilla and mandible. Mandibular second molar was the most frequent dilacerated tooth (1.6%) followed by maxillary first molar (1.3%) and mandibular first molar (0.6%).

What is Dilaceration of root?

By definition, dilaceration is an abnormal angulation or bend in the root and less frequently, the crown of a tooth.

What is ectopic eruption of teeth?

Ectopic eruption is a disturbance in which the tooth does not follow its usual course. The purpose of this manuscript is to provide a brief review regarding the incidence, etiology, classification and different management techniques used for correcting ectopically erupting permanent first molar.

When do mamelons teeth go away?

Mamelons usually occur in permanent or adult teeth. They are most noticeable up until you’re 10 years old, according to a 2020 study. The study also reported that mamelons typically go away when you’re about 25 years old.

What is crown Dilaceration?

Crown dilaceration of permanent teeth occurs due to the non-axial displacement of the already formed hard tissue portion of the developing crown at an angle to their longitudinal axis due to trauma to the primary predecessors.

Is hypodontia serious?

Severe hypodontia is the absence of six or more permanent teeth and is relatively uncommon (estimated prevalence of 0.1-0.2%). This condition may have considerable functional, aesthetic and psychological implications for the patient, as well as presenting a significant challenge for the restorative dentist.

Is hypodontia a birth defect?

Tooth agenesis is one of the most common congenital malformations in humans. Hypodontia can either occur as an isolated condition (non-syndromic hypodontia) or can be associated with a syndrome (syndromic hypodontia), highlighting the heterogeneity of the condition.

What is the most associated dental anomaly with hypodontia?

In association with hypodontia of these teeth other dental anomalies were observed. Absence of other teeth was observed as the most likely associated dental anomaly. Other anomalies recorded included disturbances in spacing of the dentition, and problems associated with tooth eruption and exfoliation.

How common is Gemination?

According to the Journal of Clinical & Diagnostic Research, gemination is also quite rare; it’s prevalent in about 0.5% of primary or baby teeth and 0.1% in permanent teeth. Gemination also more commonly occurs in your front incisors and canine teeth than molars and bicuspids, though it can still appear in those areas.

How do you fix tooth Gemination?

Your dentist may want to put a sealant on the tooth to prevent a cavity from developing. Gemination and fusion can sometimes be treated by shaving down and smoothing the double tooth to make it less noticeable. This will not be possible if the pulp is too close to the surface.

What causes enamel pearls?

According to an article in the Journal of Dental Sciences, enamel pearls form when enamel cells — called ameloblasts — travel below the gumline to the root and start producing enamel. This prevents the normal root covering from developing, leaving a nodule of enamel at the root instead of at the crown where it belongs.

Why do kids get double teeth?

When children have two sets of teeth, it’s actually because they have their set of baby teeth and adult teeth simultaneously. This happens when their set of permanent teeth come in through a way that doesn’t push the baby teeth out.

What is enamel pearl in dentistry?

Enamel pearls are tiny nodules of ectopic enamel that occur most typically on the root surface of permanent maxillary molar teeth, although mandibular molars can be affected.

How do you fix double teeth?

Treatment options usually include braces, clear aligners, or veneers. In more severe cases, tooth extraction or surgery may be recommended. If you have concerns about overlapping teeth, make an appointment to talk with your dentist or orthodontist.

What is the most commonly missing tooth?

Some people are born without certain teeth, and this condition is called congenitally missing teeth. Genetic factors cause congenitally missing teeth and this condition is often seen in generations of a family. The most common missing teeth are wisdom teeth, upper lateral incisors, and second premolars/bicuspids.

How common is a fused tooth?

Fusion is a rare developmental disorder characterized by the union of two adjacent teeth at the crown level (enamel and dentin), causing the formation of a tooth with an enlarged clinical crown. Incidence of this anomaly is approximately 0.1% in the permanent and 0.5% in the primary dentition.

What causes Mulberry molars?

The cause of mulberry teeth stems from congenital syphilis. When pregnant women with syphilis transmit the disease to their child, it can result in mulberry molars. While syphilis is a noticeable STD from a bacterial infection, notes the Mayo Clinic, congenital syphilis usually doesn’t show signs with newborns.

What causes taurodontism?

Although considered to be a developmental rarity, the precise cause of taurodontism is unknown. Genetic disorders or mutations such as: Amelogenesis imperfecta, a condition affecting the development of tooth enamel. Ectodermal dysplasia, a disorder affecting the skin, hair, nails, teeth, and sweat glands.

What is taurodontism of teeth?

Taurodontism is a disorder of tooth development and occurs most commonly in permanent molar teeth. It refers to an elongation of the pulp chamber of the tooth, which can cause the tooth to lie deep in the jaw (aveolar process). At this time the cause of taurodontism is unknown. Last updated: 7/18/2013.

How does syphilis affect the teeth?

Dental defects are the most consistent clinical manifestation of syphilis and are pronounced in teeth, which calcify in the first year of life such as permanent incisors and first molars [10].

What tooth is most affected by root Dilaceration?

Dilaceration is defined as a deviation or bend in the linear relationship of a tooth crown to its root. This occurs most often in the permanent dentition and frequently affects the maxillary incisors (Fig. 10).
