“…Various complications may occur as the result of the presence of ST including crowding, delayed eruption, spacing, impaction of permanent incisors, abnormal root formation, alteration in the path of eruption of permanent incisors, median diastema, cystic lesions, intraoral infection, rotation, root resorption of the adjacent teeth, or even eruption of incisors in the nasal cavity and retained deciduous teeth [1,59,60].…”

A supernumerary tooth (ST) is defined as any tooth or odontogenic structure that is formed from tooth germ in excess of usual number for any given region of the dental arch. They may be single or multiple and unilateral or bilateral in distribution and can occur in any region of the dental arch. These may occur in primary and permanent dentition. Supernumerary teeth are more frequent in males. They are classified based on form, morphology, location, and occurrence. Several hypotheses have been proposed to explain the occurrence of ST. However, combination of environmental and genetic factors has been proposed. Supernumerary teeth cause a range of complications like crowding, displacement, dilacerations, cyst formation, and so forth. Early identification and appropriate treatment plan should minimize the potential complications caused by ST.

“…A supernumerary tooth is defined as an extra tooth or tooth like structure in addition to the 32 permanent teeth; usually presents in the permanent dentition or the 20 deciduous teeth usually formed in the temporary dentition. 3,4 Supernumerary teeth may exist unilaterally or bilaterally, be single, double or multiple, 5 however, they mostly occur bilaterally. 6 They can be erupted, impacted or exhibit ectopic eruption, 3 and can be similar to the normal teeth or be amorphous.…”

“…6,7 The prevalence rates of supernumerary teeth in Caucasian populations in the permanent and primary dentition are 0.1 to 3.6% and 0.3 to 0.8% respectively. 4,6,8,9 The etiology leading to supernumerary teeth is not well understood, but there are many possible causes that include atavism, excessive growth of the dental lamina, and dichotomy of the tooth germ, heredity and genetics. 4 Supernumerary teeth are classified according to their location.…”

Objective: To determine the prevalence of permanent tooth anomalies in patients attending the graduate orthodontic clinic at the State University of New York at Buffalo. Materials and methods:Charts of 496 subjects (310 females and 186 males) met the inclusion criteria for this study. The mean ages were 16 years and 3 months for the combined gender sample that received orthodontic treatment in the graduate orthodontic clinic between 2007 and 2010. Full pretreatment records (intraoral photographs, digital study models, lateral cephalograms and panoramic radiographs) were used for the assessment. Charts were examined for these anomalies: agenesis, supernumerary, impaction and delayed tooth eruption. Subjects were categorized by gender and ethnicity. The percentages of the anomalies were assessed according to type of malocclusion, gender, race, location, tooth class and region in the dental arches.Results: Sixty-four subjects (12.9%) had at least one occurrence of delayed eruption and impaction (DEI), followed by 47 subjects (9.5%) who had at least one occurrence of agenesis, and seven (1.4%) had a supernumerary condition. Approximately 80% of the subjects had no dental anomalies. The presence of more than one anomaly was observed in 61 subjects. Twelve subjects (2.4%) had both agenesis and DEI. Agenesis tended to be more common in class II malocclusions (p = 0.012). Conclusion:The prevalence of permanent tooth anomalies was (20.4%). The percentage occurrence of DEI was the highest (12.9%) followed by dental agenesis (9.5%) and supernumerary teeth (1.4%) in the orthodontic patients at the State University of New York at Buffalo.

“…Those extra teeth are generally characterised by specific morphology. The most frequent form is the conical type 8,17 , less frequent are the tuberculate or barrelshaped and molariform types 7,24 . The term supernumerary nasal tooth (SNT) is commonly used for such a clinical finding.…”
