Supernumerary teeth (hyperdontia) are relatively common in the general population and occur more frequently in patients with a family history of such teeth. Supernumerary teeth have been reported in many genetic syndromes, but multiple supernumerary teeth occurring as an isolated non-syndromic trait are rare. This article describes a rare non-syndromic variety of multiple impacted supernumerary teeth in two brothers.

The presence of supernumerary teeth, although not uncommon, occurs usually in the premaxillary region. Furthermore, examples of multiple supernumerary teeth in one patient are rare. A case involving the presence of multiple supernumerary teeth in all quadrants in described.
Supernumerary teeth are relatively common in the general population and appear to be more likely to occur in patients with a family history of such teeth. It is important that these teeth are identified and in some cases removed before undertaking orthodontic treatment. This article describes two patients who presented with supernumeraries, and their treatment.

The cause of disturbance of dentoalveolar arch formation in the front part of the maxilla in one patient was the maxillary central incisors eruption delay due to retention of supernumerary teeth situated in the region of upper central incisors. A positive result of the treatment was achieved with the use of surgical and orthodontic methods. The distinctive feature of the orthodontic method was retained tooth displacement (by traction) into the dentition.
Supernumerary teeth, which usually appear in small numbers and are easily dealt with, may affect the permanent dentition if not removed. In this paper the case of multiple supernumerary teeth in the presence of a complete dentition is reported.

Multiple supernumerary teeth affecting all four quadrants of the jaw are a rare dental anomaly which has become a chance finding on routine dental panoramic tomography (DPT). In this paper, two cases from the English-speaking Caribbean are reported. The role of radiography in the diagnosis and management of this rare developmental dental anomaly is emphasized. The paper stresses the importance of ruling out associated syndromes such as Gardner's Syndrome, cleidocranial dysostosis and cleft lip and palates, as multiple supernumerary teeth are usually related to such conditions. There is a review of the literature as it relates to supernumerary teeth.
A case is described in which, after removal of midline supernumerary teeth on two separate occasions, an unerupted central incisor was brought into the arch with the aid of neodymium-iron-boron magnets. Once the incisor was visible, a pre-adjusted upper edgewise appliance was used to guide the tooth into its correct position.
A 9-year-old boy suffering from cleidocranial dysplasia presented with multiple unerupted permanent teeth and five unerupted supernumerary teeth. During a 4-year observation and treatment period he developed nine more supernumerary teeth at a time when normally new teeth would no longer be forming. By the age of 13 years and 5 months a total of fourteen supernumerary teeth had been produced and it is possible that more teeth may develop in the future.
This paper reports on a case of a 18-year old male subject with continuous complaints in the right cheek. Several roentgenograms show a cystic and a X-ray dense, sharp-edged structure in the right maxillary respectively ethmoidal sinus. Under surgery a supernumerary molar was found in the right ethmoidal sinus as well as a follicular cyst in the right maxillary sinus.
