The eruption of a tooth into the nasal cavity is rare and incidental finding during routine clinical or radiological examination. Since 1960s there were more than 60 reported cases teeth. To best our knowledge, this only sixth case report supernumerary intranasal canine in selected period. A 22-year-old male presented with history recurrent rhinorrhea, congestion, tension headaches, insomnia bu...

PURPOSE Although intracoronal radiolucencies in radiographs of unerupted teeth have been reported for several decades, the prevalence of this condition remains unknown. This study determined the prevalence and associated dental conditions of permanent teeth showing pre-eruptive dentin radiolucencies in bite-wing radiographs of school children attending two school dental therapy training centers...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014205000 DESCRIPTION A 15-year-old boy reported with extra teeth in his upper left and right back region since 4–5 years. Medical and family history did not reveal any related positive findings. On detailed intraoral examination, supernumerary teeth were found dis...

S upernumerary teeth occur most commonly in the maxillary anterior region. When in the midline area, such a tooth is commonly referred to as a mesiodens with most remaining unerupted. 1, 2 The prevalence of supernumerary teeth is reported to be from I to 3%. 3‘4 Supernumerary teeth may cause or be related to over-retention of primary teeth, impaction, or ectopic eruption of nearby permanent tee...

A retrospective study of 26 patients with maxillary incisor root resorption relating to the presence of an ectopic canine was undertaken from case records. The group consisted of nine male and 17 female patients with a mean age of 12.5 years. There was a total of 35 resorbed teeth, 26 lateral and nine central incisors, and these were related to 32 ectopic canines. The resorption tended to be ex...

In common with most mammals, humans form only two dentitions during their lifetime. Occasionally, supernumerary teeth develop in addition to the normal complement. Odontoma represent a small group of malformations containing calcified dental tissues of both epithelial and mesenchymal origin, with varying levels of organization, including tooth-like structures. The specific cell type responsible...

AIM To examine the prevalence of different types of dental anomalies in children with nonsyndromic cleft lip, unilateral cleft lip-palate, and bilateral cleft lip-palate. MATERIALS AND METHODS A sample of 90 patients (aged 4-20 years) affected by isolated cleft lip, unilateral and bilateral cleft lip and palate was examined. Cleft patients were classified into one of three groups according to...

Dentigerous cysts are the most common developmental odontogenic cyst of the jaws. They are more frequent in males and although most often affected teeth are maxillary canines and mandibular third molars, they may also be related with supernumerary or an ectopically erupted tooth. Our aim was to report the management of ectopic third molar tooth related with a dentigerous cyst in maxillary sinus...

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...

The evolution of joints, which afford skeletal mobility, was instrumental in vertebrate success. Here, we explore the molecular genetics and cell biology that govern jaw joint development. Genetic manipulation experiments in zebrafish demonstrate that functional loss, or gain, of the homeobox-containing gene barx1 produces gain, or loss, of joints, respectively. Ectopic joints in barx1 mutant a...
