“…At age 22 years, all supernumeraries reported were still present, with almost complete root formation and a chronological age of 13 to 14 years. Many other studies have also reported late-developing supernumerary teeth in the premolar region [18, 29, 32, 34, 36–38].…”

Supernumerary teeth in the premolar region, unlike other supernumeraries, occur more often in the mandible where they are generally of the supplemental type. Occasionally, they are conical or smaller than normal, particularly in the upper premolar regions. They might occur singly or in multiples, be erupted or impacted, but the majority have been found to be unerupted and asymptomatic. The prevalence of supernumerary teeth in the premolar region has been demonstrated to be between 0.01 and 1 percent depending on the population studied. Interestingly, populations from the East or Africa are known to be the most affected. Various theories have been suggested to explain the etiology of supernumerary teeth in general including both genetic and environmental factors. Furthermore, it has been suggested that supernumerary premolar teeth belong to a third (postpermanent) series, developing from extensions of the dental lamina. Several consequences can result from the presence of supernumerary premolars, especially in the mandible, such as cyst formation, transposition, and other clinical scenarios.

“…However, the supernumerary crypt and early stage of mineralization can be easily overlooked due to the lingual position relative to the normal premolar roots. Moreover, supernumerary premolars may interfere with orthodontic space closure and affect the stability of ortho dontic treatment [7,10,15].…”

“…In a several reports of late-developing supernumerary teeth, they were mostly found in the mandibular premolar region [2,5,6,9,11,14,17]. Their prevalence in an orthodontic population has been reported to be 0.64% [10].…”

A B S T R AC THypo-hyperdontia is a very rare condition in which dental agenesis and supernumerary tooth (or teeth) occur concomitantly. The present case report describes late-forming multiple supernumerary teeth in all quadrants in a nonsyndromic boy with a radiographic diagnosis of mandibular incisor hypodontia made when the patient was 9 years of age. Developing supernumeraries were detected after uneventful orthodontic treatment using fixed appliances on a panoramic radiograph taken shortly after debonding at the age of 15. Cone beam computed tomography was performed to determine the exact location of the extra teeth relative to normal dentition and identify possible root resorption. To the best knowledge of the authors, this is the first reported case of late-developing supernumeraries being a part of the hypo-hyperdontia condition. In conclusion, general dental practitioners should be aware of the rare possibility that a generally healthy individual may develop multiple supernumerary teeth even with the previous diagnosis of hypodontia.

“…Recently, the term "third dentition" has been proposed to describe supernumerary teeth that develop and appear after the completion of the usual configuration of 32 permanent teeth, representing a dental anomaly of number in the human species (1)(2)(3). Although this clinical phenomenon is relatively frequent in the global population (with an estimated prevalence between 1.5 and 3.8% in permanent dentition), the exact etiology of this anomaly remains unknown (2,4,5).…”

Supernumerary premolars have received special attention due to their development during adolescence, representing a dental anomaly of number that could be attributed to a “third dentition” of human species. The goal of its treatment is to avoid possible interference in occlusal development, as long as the benefits of supernumerary removal outweigh its risks. This is a case report of the orthodontic and surgical management of a patient that has been in clinical and radiographic follow-up along eight years (since childhood through adolescence) with the emergence of non-syndromic multiple supernumerary premolars, showing an apparent familiar pattern.
