Although hypodontia and supernumerary teeth are often considered as mutually exclusive conditions, this case report presents an unusual case of hypodontia and a supernumerary tooth occurring simultaneously. An adolescent male was referred to the local hospital department regarding upper arch crowding. Plain film radiographs confirmed the congenital absence of both lower lateral incisors in addi...

Deeply impacted supernumerary teeth in the anterior maxillary cannot be generally removed by the conventional labial or palatal surgical approach because of the risk of damaging the surrounding soft tissues and the possibility of injuring the roots of adjacent permanent teeth. In piezosurgery, bony tissues are selectively cut, thereby avoiding the soft tissue damage caused by rotary cutting ins...

In this report we describe a combined orthodontic and surgical treatment for a 14-year-old boy with severe skeletal class III deformity and dental problem. His upper posterior primary teeth in the left side were over-retained and 6 maxillary teeth (bilateral central incisors and canines, left first and second premolars) were impacted, together with 5 supernumerary teeth in both arches. The trea...

This paper reports the management of two clinical cases, in which the upper right central incisor was fused with a supernumerary tooth and the upper left central incisor was macrodontic. A radiographic examination revealed that the fused teeth had two separate roots. Hemisectioning of the fused teeth was performed, the supernumerary portion was extracted and the remaining part was reshaped to r...

Dentigerous cysts can develop from unerupted primary, permanent, or rarely supernumerary teeth. When a supernumerary tooth is in the maxilla, near the midline, it is called a mesiodente. Such a mesiodente lies in the palate and a cyst developing about this tooth can extend directly up into the nasal fossae. More commonly a dentigerous cyst arising from unerupted maxillary teeth occurs about the...

Anomaly in the number of teeth may manifest as a supernumerary tooth. Occurrence of a supernumerary tooth in the mandibular incisor region is uncommon. This report presents a rare case of five mandibular permanent incisors in a nine year old non-syndrome healthy male child. Clinical and radiographic examination revealed the presence of a supplemental (type of supernumerary) permanent incisor in...

INTRODUCTION Cleidocranial dysplasia (CCD) is a rare inherited skeletal dysplasia, often with prolonged retention of deciduous teeth and several impacted permanent successors and supernumerary elements. METHODS This article demonstrates the usefulness of titanium screws for orthodontic anchorage to induce eruption of the impacted teeth in a patient with CCD. A boy, aged 10 years 11 months, ha...

Supernumerary teeth or hyperodontia is an infrequent developmental alteration that appears in any area of the dental arches and can affect any dental organ. Multiple hyperodontia can be associated with several syndromes such as Gardner's, cleidocranial dysplasia, tricho-rhino phalangic syndrome or in patients with cleft lip and palate. However, it can be present in patients without any systemic...

The present report describes a case of Noonan's syndrome from a dental viewpoint. Noonan syndrome is an autosomal dominant multisystem disorder. Congenital heart deformities, short stature, thoracic deformities, short neck with webbing, hypertelorism, and malocclusions are some of the frequently observed clinical features. Atypical dental anomalies such as multiple unerupted permanent teeth, mu...

UNLABELLED Unerupted supernumerary teeth, depending on the morphology, number and distribution can give rise to various alterations in the eruption and development of those permanent teeth to which they are related. OBJECTIVES We aimed to make an epidemiological and descriptive study of the clinical characteristics of patients in Barcelona, their surgical treatment and how said treatment was ...
