Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. This report presents regenerative endodontic treatment of a necrotic immature tooth with Oehler's type III dens invaginatus of a nine-year-old female patient. A diagnosis of dens invaginatus (Oehler's type III) and a large periapical lesion was est...
The present study aimed at evaluating the prevalence of tooth ankylosis in deciduous molars of Caucasian children with cleft lip and/or palate aged 5 to 12 years, of both genders. A total of 330 patients seen at the Hospital for Rehabilitation of Craniofacial Anomalies of the University of São Paulo for routine treatment were clinically evaluated. The prevalence of ankylosis was analyzed in rel...
Regional odontodysplasia (ROD) is uncommon developmental anomaly, which tends to be localised and involves the ectodermal and mesodermal tooth components. A five-year-old female was referred to Department of Child Dental Health at the Leeds Dental Institute regarding malformed primary teeth. On examination 64, 74, and 72 had localised hypomineralized enamel defect. The crown of 55 was broken do...
Fusion represents the union of two normally separated tooth germs [1]. It is a dental twinning anomaly and also known as double teeth, conjoined teeth or twinned teeth. Clinically, the appearance of the involved teeth may be normal sized or large, depending upon the stage at which embryological union occurs during development. It is commonly confused with gemination, particularly if it involves...
Background and Aim: The aim of the present study was to determine the incidence of transmigrated maxillary and mandibular canine teeth and also of the other impacted teeth, apart from third molars, in a Turkish dental patients subpopulation. Materials and Methods: This was a retrospective study of 2900 panoramic radiographs (PRs) taken from patients who were referred to the Faculty of Dentistry...
This paper reports the oral health approach of a child with Coffin-Siris syndrome. syndrome is multisystem congenital anomaly caused by mutations in genes BRG-1-associated factors complex. Individuals this have been described hypoplasia or aplasia fifth digit nails phalanges. Other features include growth deficiency, developmental and intellectual delay, other organ-system abnormalities. Clinic...
BACKGROUND Mesiodens is the most common type of supernumerary tooth found in the premaxilla. It might be discovered by the clinical examination by chance on a radiograph or as the cause of an unerupted maxillary central incisor. The genetic transmission of supernumerary and impacted teeth is poorly understood. Mirror imaging in twins has been reported frequently in relation to several unilatera...
Abstract Joubert syndrome (JS) is a rare autosomal recessive neurodevelopmental disorder that usually diagnosed late in pregnancy or postnatally based on pathognomonic midbrain–hindbrain malformation seen magnetic resonance imaging brain, which consists of the hypoplasia cerebellar vermis, thickened superior peduncles, and deepened interpeduncular fossa described as molar tooth sign. The recurr...
Dilaceration is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth, but the criteria in the literature for recognizing root dilaceration vary. Two possible causes of dilaceration are trauma and developmental disturbances, and it has also been proposed that it might be associated with some developmenta...
Dens evaginatus is a rare dental anomaly characterized by the development of a tubercle on the occlusal surface of the tooth and can cause pulpitis, pulp necrosis, and periapical periodontitis due to tubercular fracture or attrition. Unlike with caries, pain caused by dens evaginatus may manifest itself in a distant location. Therefore, diagnosing the cause of that pain may prove problematic. D...
