Odontomas are nonaggressive, hamartomatous developmental malformations or lesions of odontogenic origin, which consist of enamel, dentin, cementum and pulpal tissue 'Erupted odontoma' is a term used to specifically denote odontomas, which are exposed into the oral cavity. These are rare entities with only 25-30 cases being reported so far in the dental literature. Here, we present a rare case o...

A two-year, 2-month old girl with Ehlers-Danlos syndrome Type VII is described. The patient presented with bleeding after tooth brushing, and exhibited microdontia and yellow discoloration of teeth. She had carious teeth, but did not exhibit periodontal disease, poor wound healing after extraction, radiographic evidences of pulp stones, or malformed roots. Microscopic examination of a decalcifi...

Ellis–van creveld syndrome is a rare autosomal recessive syndrome of the heart, skeleton and most of the ectodermal derivatives. It is caused due to genetic defects in the chromosome 4p16; it belongs to short rib-polydactyly group (SRP). It is characterized by short ribs, short limb, polydactyly, ectodermal dysplasia and congenital heart defects. The oral manifestation is one of the main charac...

A young child being diagnosed with cancer naturally generates a pretty melancholy reaction. Each cancer can be managed with a vast array of treatment options that are available either individually or as a combination, the final goal of which is total eradication of the condition in the affected individual. Since, most of these treatments are administered during the age of tooth formation, they ...

Oculodentodigital syndrome (ODD) is a rare, usually autosomal-dominant disorder that is characterized by developmental abnormalities of the face, eyes, teeth, and limbs. The most common clinical findings include a long, narrow nose, short palpebral fissures, type III syndactyly, and dental abnormalities including generalized microdontia and enamel hypoplasia. Recently, it has been shown that mu...

Two male siblings aged 12 and 15 years (Figure 1) presented with growth retardation, limb abnormalities and, defective teeth and nail since childhood. There was no history of similar defects in other family members. On examination their height was 114 cm and 130 cm (expected height; 169 cm and 150 cm) respectively. There were hypoplastic and dystrophic nails, and microdontia and hypodontia on d...

The difficulties traditionally faced by functional morphologists in representing and interpreting three-dimensional objects can now be mostly overcome using available laser and computer imaging technologies. A practical method for three-dimensional imaging of small mammalian teeth using confocal microscopy is reported. Moulding and casting of the teeth were first performed, followed by confocal...

* Variation in the size and shape (physiognomy) of leaves has long been correlated to climate, and paleobotanists have used these correlations to reconstruct paleo-climate. Most studies focus on site-level means of largely nonoverlapping species sets. The sensitivity of leaf shape to climate within species is poorly known, which limits our general understanding of leaf-climate relationships and...

The aim of this study was to evaluate the prevalence and clinical manifestation of developmental absence of maxillary permanent lateral incisors in the Portuguese population. The study group comprised 16 771 patients observed between 1993 and 2000 at the Faculty clinic. Two hundred and nineteen patients were found to have missing upper lateral incisors (131 females and 88 males, with ages rangi...
