Summary
Supernumerary premolars, extra teeth, are rare, affecting 0.24% of patients. Complications like pain and root resorption were observed, with surgical intervention considered for affected individuals.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Radiology
Background:
- Non-syndromic supernumerary premolars are uncommon dental anomalies.
- Understanding their incidence and associated complications is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To determine the incidence of non-syndromic supernumerary premolars.
- To classify these supernumerary teeth.
- To identify complications linked to their presence.
Main Methods:
- Retrospective cohort study of 8400 panoramic radiographs (1998-2008).
- Analysis of supernumerary premolar number, location, patient demographics, complications, and treatments.
- Data collected from Oral and Maxillofacial Surgery Services.
Main Results:
- Incidence of 0.24% (20 supernumerary premolars in 10 patients).
- More frequent in females (7) than males (3).
- Complications included pain and adjacent tooth root resorption in 4 patients; 18 teeth were extracted.
Conclusions:
- Supernumerary premolars are infrequent, with a higher prevalence in females.
- Complications may necessitate surgical extraction.
- Observation is an alternative for asymptomatic cases.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:29Nondisjunction
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
01:21Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
01:49Meiosis I
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by a...
