Introduction: Cutaneous tuberculosis (CTB) is a rare presentation of extrapulmonary tuberculosis (TB) with various clinical manifestations. Tuberculids, a type of CTB, are probably the result of hyperergic immune reaction induced by Mycobacterium tuberculosis. Lichen scrofulosorum (LS) is a rare tuberculid mostly seen in children and young adults with or without other manifestations of tubercul...

Introduction Genetic factors contribute to the aetiology of the ectopic canine (EC) (OMIM 189490), the inheritance pattern being autosomal dominant with variable expression and incomplete penetrance. However there is also evidence for an epigenetic component [1]. The Runx2 gene is intimately involved in the mechanism of tooth eruption. It controls differentiation and maturation of osteoblasts a...

odontoma.2,3 Compound odontomas consist of tooth-like structures that radiographically appear as opacities. Complex odontomas comprise a mixture of odontogenic tissues without dental organization.2,4 Clinically, three types of odontomas are recognized in the literature: central (intraosseous) odontoma, peripheral (extraosseous or soft tissue) odontoma, and erupted odontoma.2,5 Odontomas are oft...

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition. A midline supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise e...

Although preventive measures have reduced caries, premature loss of pulpally involved primary teeth remains a common problem. The resultant mesial drift of the permanent teeth frequently leads to malocclusion. Retention of the pulpally involved primary tooth to preserve arch space is preferable to space maintenance if the tooth can be restored to normal function and is free of pathology. Additi...

The prevalence rate of impacted primary teeth is rare, still we can see impacted teeth in ectodermal dysplasia anhydrotic (EDA), endocrine deficiencies, metabolic disorders and local factors like cysts, tumors, trauma and thickened overlying bone or soft tissue. In cases of EDA, delayed tooth eruption is one of the characteristic finding. Present case report related to a rare case of primary te...

Odontodysplasia is a rare clinicopathologic condition that has a variety of expressions, including a range of tooth coloration, formation of hypoplastic enamel affecting one or multiple teeth, bizarre radiographic appearance, and delayed eruption of teeth. An unusual case is presented of bilateral regional odontodysplasia associated with a vascular nevus of the face and neck. A review of the et...

The case of a 3 11/12-year-old Chinese boy with the dental abnormalities of "otodental" dysplasia is reported. Hearing was normal. Dental anomalies consisted of delayed eruption of globe-shaped molars, bulbous deciduous canines, and double pulp chambers in the molars. Radiographs taken 4 years later showed taurodontic molars, supernumerary microdontic teeth, retarded formation of premolars, and...

INTRODUCTION Cleidocranial dysplasia is a rare congenital defect of autosomal dominant inheritance caused by mutations in the Cbfa1 gene, also called Runx2, located on the short arm of chromosome 6. It primarily affects bones which undergo intramembranous ossification. This condition is of clinical significance to dentistry due to the involvement of the facial bones, altered eruption patterns a...
