The most common congenitally missing teeth are the lateral incisors in the upper jaw and the second premolars in the upper and lower jaws. The lateral incisors are the two teeth located on either side of your front teeth, and just in front of the canines which are the larger and pointier teeth.
Which teeth are most commonly congenitally missing?
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.
What teeth are most commonly missing due to hypodontia?
Most affected individuals lack only one or two teeth, with permanent second premolars and upper lateral incisors the most likely to be missing. Both environmental and genetic factors are involved in the aetiology of hypodontia, with the latter playing a more significant role.
Which incisor is more likely to be congenitally missing?
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 teeth are congenitally missing in hypodontia?
If you are born with lesser teeth than an average person, you have hypodontia. It is also commonly known as congenitally missing teeth (CMT). It affects both baby and permanent teeth. The most common congenitally missing teeth are second premolars, wisdom teeth, and upper lateral incisors.
How common are congenitally missing teeth?
This hypodontia is one of the most common developmental abnormalities in dentistry, with up to 20% of all adults missing at least one tooth. When children have a congenitally missing baby tooth, there generally will not be a permanent tooth developing in the gums underneath it either.
Which premolar is congenitally missing?
After third molars, mandibular second premolars are the most common congenitally missing teeth. Polder B.J.
What causes congenitally missing permanent teeth?
Missing teeth are the results of increased maternal age, low birth weight, multiple births, early exposure to certain infections, trauma, or drugs. Hypodontia usually is the result of genetic disorders such as ectodermal dysplasia or Down syndrome.
What are hypoplastic teeth?
Dental enamel hypoplasia is an enamel defect characterized by thin or absent enamel. In some cases, the defect occurs on only part of a tooth’s surface, resulting in pits or grooves in the tooth’s enamel. In other cases, an entire tooth may have an overly thin layer of dental enamel or may have no enamel at all.
How common is congenitally missing lateral incisors?
The prevalence rate for congenitally missing upper lateral incisors in the orthodontic adolescent population aged 12 to 18 years was found to be 3.77% in the present study while females were found to have a greater percentage of agenesis of the upper lateral incisors (2.8%) as compared to the males (0.9%).
Is it common to be missing lateral incisors?
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.
What teeth are the incisors?
The incisors are the eight teeth that are most visible in the front of the mouth. There are eight incisors in total, four on the top and four on the bottom. These are often called your front teeth. The purpose of these teeth are to take bites out of food.
What is Taurodontism of teeth?
Taurodontism is a dental anomaly defined by enlargement of the pulp chamber of multirooted teeth with apical displacement of the pulp floor and bifurcation of the roots. Taurodontism can be an isolated trait or part of a syndrome.
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.
Hypodontia is also related to extradermal dysplasia, cleft lip and palate, van der Woude syndrome, and Down syndrome (18). The teeth that are mainly related to hypodontia are maxillary second premolars or maxillary lateral incisors (10).
