How common is missing lateral incisor?

According to epidemiological studies, one or both of the maxillary lateral incisors are congenitally missing in approximately 2% of the population. (1) Maxillary laterals are the third most common missing teeth behind third molars and mandibular second premolars.

Is missing lateral incisors hereditary?

Congenitally missing teeth are teeth that never appear and are not trapped in the gums – they just do not exist in some people! The condition, which usually affects the lateral incisors and the second premolars, is often a harmless genetic trait passed down from parents to their children.

How common is missing upper lateral incisors?

Maxillary lateral incisor agenesis (MLIA) is the most common congenitally missing permanent tooth condition in the maxillary anterior region (esthetic zone), representing approximately 20% of all dental anomalies [1-3].

Which incisor is more likely to be congenitally missing?

The most common congenitally missing teeth were mandibular second premolars 23.34%, maxillary second premolars 22.02%, maxillary lateral incisors 18.94% and maxillary first premolars 14.74%, respectively [Table 2].

Can braces fix missing lateral incisors?

What is common among all people who are born without lateral incisors is that they can resolve their issues through orthodontic treatment, whether through the use of traditional braces to close the space or through the creation of more space to accommodate tooth restorations.

Missing Upper Lateral Incisors

What can I do with missing lateral incisors?

There are three treatment options that exist for replacing missing lateral incisors. They include canine substitution, a tooth-supported restoration, or a single-tooth implant.

How common is hypodontia?

The prevalence of hypodontia is 2 to 8% of the general population (excluding third molar) and oligodontia is 0.09%. to 0.3%.

What is the most common missing tooth?

The mandibular second premolar was reported as the most commonly missing tooth in most studies, followed by the maxillary lateral (the most commonly missing in the rest).

What are the commonest congenitally missing teeth?

The most common congenitally missing teeth are wisdom teeth, upper lateral incisors, and the second premolars(source).

What are the most commonly missing permanent teeth?

Missing wisdom teeth are the most common, followed by premolars (located between the canines and molars), upper lateral incisors (located on either side of the central incisors, or “front teeth”), and lower central incisors (front bottom teeth).

What is a common developmental anomaly for lateral incisors?

Talons cusp and palate-radicular groove are commonly occurring developmental anomalies in permanent maxillary lateral incisors. These anomalies present with various esthetic and functional complications that require prophylactic and definitive treatment plans.

Is missing teeth a disability?

Therefore, an individual should be considered to have a dental disability if orofacial pain, infection, or pathological condition and/or lack of functional dentition affect nutritional intake, growth and development, or participation in life activities.

How common is oligodontia?

It is a relatively rare condition affecting 0.1–0.2 % of the population. Oligodontia can occur as an isolated nonsyndromic condition or as a part of a syndrome.

Why are some people born with a missing tooth?

Tooth decay, gum disease, and injury are common causes of missing teeth. 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.

What is the order of most frequent to least frequent congenitally missing permanent teeth?

The most commonly missing teeth are the third molars, mandibular second molars, maxillary permanent lateral incisors, and maxillary second premolars. In contrast, the least commonly missing permanent teeth are the maxillary central incisors, the maxillary and mandibular first molars, and the mandibular canines.

How do you fix congenitally missing teeth?

Can braces fix hypodontia?

While braces work for some hypodontia problems, they aren't likely to work if the gap is too big or if your child has multiple gaps in the same part of the mouth. If existing teeth can't cover the gap without moving too much themselves, then your teen needs a different solution.

Can you get braces with one tooth missing?

You may have wondered whether you can get braces if you have one or more missing teeth. The good news is that the answer is most likely yes. In fact, braces can be a great option for people missing a tooth, as they can close or widen gaps to leave the perfect amount of space for a replacement.

What are lateral incisors?

Lateral incisors are the two teeth located to the right and left sides of the central incisors. They are also referred to as being in the distal position, or away from the center of the jaw.

What is the second tooth in hypodontia?

The second premolars – these are the teeth right in front of your molars. One may sometimes be removed during braces treatment, but if your child is missing this permanent tooth, chances are it's due to hypodontia.

What is a ghost tooth?

Teeth in a region or quadrant of maxilla or mandible are affected to the extent that they exhibit short roots, wide open apical foramen and large pulp chamber, the thinness and poor mineralisation qualities of th enamel and dentine layers have given rise to a faint radiolucent image, hence the term "Ghost teeth".

What is hypodontia vs anodontia?

Hypodontia refers to the absence of fewer than 6 teeth (not including third molars). Oligodontia refers to the absence of 6 or more teeth (not including third molars). Anodontia is the complete absence of teeth. Hypodontia is more common in the permanent dentition than in the primary dentition.

When is hypodontia diagnosed?

Hypodontia is usually diagnosed in children when they are 8 to10 years old. The reasons for this dental development failure are complex. Many genes are involved and the details of why some are afflicted by the condition are not all known.

What syndromes are associated with oligodontia?

Oligodontia can occur in association with various genetic syndromes, like ectodermal dysplasia, Van Der Woude syndrome, Down syndrome and Reiger syndrome or as a nonsyndromic isolated familial trait, or as an infrequent finding.

Is oligodontia a disability?

Conclusions: Oligodontia is a heterogeneous condition. Patients with oligodontia can be classified as having three different types according to the extent of their disability and the complexity of their prosthodontic requirements.
