The incidence of nonsyndromic supernumerary premolars is rare. Supernumerary premolars are likely to undergo pathological changes. The most commonly encountered complications with these teeth are dentigerous cyst and root resorption of the adjacent tooth. This paper is about impacted double fused supernumerary premolars in the right mandiblular body associated with an impacted first premolar in...

Dentigerous cysts are the most common odontogenic cysts of the jaws. The dentigerous cyst arise from around the crown of impacted, embedded, or unerupted teeth. Most often they involve mandibular third molars followed by maxillary canines, maxillary third molars.The main reason of dentigerous cyst is unknown but it rarely occurs around a supernumerary tooth. Only 5% of dentigerous cysts involve...

An accurate diagnosis of the morphology of the root canal system is a prerequisite for successful root canal treatment.1 Frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have an anatomical variations or additional root canals.2 Supernumerary root is a developmental condition and may involve any tooth. The incidence of ...

The aim of this report is to present a case of dens invaginatus asymptomatic discovered after exam cone beam computed tomography. A 20-year-old patient attended the clinic Radiology to perform tomography to fracture research at the root of the tooth 15. However, the examination was observed the presence of a conoid supernumerary tooth between the tooth located roots 11 and 12, which had a hyper...

Here we report a tooth of a large archosauriform from the Upper Triassic of New Mexico, USA that displays developmental anomalies of carina formation. This tooth has two supernumerary carinae, both on the lingual side of the tooth. Previously, carina anomalies of this sort were primarily known from theropod dinosaurs, but always from the labial surface. Integrating this specimen into a reassess...

The aim of the present study was to examine whether a putative relationship exists between the Class II division 2 craniofacial type and congenital anomalies of the dentition, such as missing teeth, peg-shaped laterals, transpositions, supernumerary teeth and canine impactions. Two hundred and sixty-seven untreated patients with Class II division 2 malocclusion were examined. The results show t...

A case is presented of a nine-year-old male having a supernumerary maxillary right first primary molar together with a supernumerary maxillary right first premolar. The implications of early diagnosis and orthodontic management are discussed. The occurrence of supernumerary teeth in both the primary and permanent dentitions in the same patient seems to be rare. A review of the literature (inclu...

Dentigerous cysts are developmental odontogenic cysts associated with the crown of an unerupted tooth most commonly located at permanent Mandibular 3rd Molars and the Maxillary Canines. They rarely involve deciduous teeth and supernumerary teeth [5%]. We report successful management of two rare cases of maxillary labial swelling due to a dentigerous cyst associated with an impacted mesiodens. T...

Dens invaginatus is a rare developmental malformation resulting from an alteration in the normal growth pattern of the dental papilla. Teeth in both maxillary and mandibular arches may be affected, but the permanent maxillary lateral incisors are the most frequently involved teeth. The invagination ranges from slight accentuation of a lingual pit to an anomaly occupying most of the crown and ro...

Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stages. They are of great concern to the dentists and parents because of the eruption, occlusal, and esthetic problems they can cause. Supernumerary teeth occur more frequently in the permanent dentition but rarely in primary dentition and more often seen in males. A s...
