Tooth transposition is a rare dental anomaly that often represents a challenge for the clinician. The case of a girl with skeletal Class III malocclusion and concomitant maxillary canine-first premolar bilateral transposition, followed from 7 to 17 years of age, is presented. After a first phase of treatment aimed at resolving the Class III malocclusion, the transposition was maintained and the...

a 20-year-old man presented with the history of pain and swelling in the anterior maxillary segment. the periapical radiography was indicative of a dental anomaly in right maxillary lateral incisor. due to the insufficient information from conventional radiography, cone-beam computed tomography (cbct) was ordered. cbct showed apical root resorption, large apical lucency and two separate canals ...

The talon cusp, or dens evaginatus of anterior teeth, is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusplike structure projecting from the cingulum area or cementoenamel junction. This occurs in either maxillary or mandibular anterior teeth in both the primary and permanent dentition. This article reports five cases of talon cusp, two of them bi...

Taurodontism is the morphoanatomical change in the shape of a tooth, which involves enlargement of the body of the tooth and shortening of the roots. Although a rare dental anomaly, unusual radicular form presents with challenging endodontic considerations. Endodontic management of taurodont teeth has been described as complex and difficult. The present article describes a brief literature revi...

Gemination or Schizodontism, a relatively uncommon dental anomaly, is characterized by a tooth with a bifid crown and a common root and root canal. It is commonly seen in primary dentition and gemination in a supernumerary tooth is a rare phenomenon. The purpose of this paper is to present an unusual case wherein gemination has occurred in a lingually placed mandibular supernumerary third premo...

Haim-Munk syndrome is an extremely rare autosomal recessive disorder characterized clinically by palmoplantar hyperkeratosis, aggressive periodontitis with severe alveolar bone destruction, onychogryphosis, pes planus, arachnodactyly, and acro-osteolysis. Consanguinity seems a notable prerequisite. The aim of this study was therefore to report one case of this syndrome and to focus on the perio...

Dental lamina cyst or alveolar cyst is a commonly diagnosed developmental anomaly in the mouth of newborns. They are quite often mistaken as natal teeth if present in the lower anterior region. Although the prevalence is high, they are rarely seen because of the transient nature of the lesions. They are self limiting and disappear spontaneously a few weeks or months after birth. Hence no treatm...

Tooth agenesis is the most common of all dental developmental disorders. The mandibular second premolars are the teeth most commonly found missing (2.2 to 4.1%) after the third molars. There are more studies on tooth agenesis than the other malformations but yet they are limited. This article reviews the studies related to agenesis of mandibular second premolars and the underlying mechanisms be...

In his book The Structure of Scientific Revolutions, Thomas Kuhn argued that a scientific revolution takes place as the result of an episode of noncumulative changes where one paradigm is replaced in whole or in part. Kuhn observed that the process of a scientific revolution begins with an existing paradigm, during which normal science is performed. Eventually, an increase in anomaly leads to a...
