Dens in dente in mesiodens is rare. Supernumerary teeth cause various complications such as failure of eruption of permanent teeth, malocclusion, development of cyst and various pathologies. So, management of such anomalies are important.
Background: Early childhood is an important stage in child's life. Normal growth and development at this stage can be hindered by the common, but preventable, conditions of early childhood caries (ECC).It has been demonstrated that children with higher counts of Streptococcus mutans and Lactobacilli are 5 times more prone to have early childhood ca...
Supernumerary teeth are additional teeth or tooth-like structures that can develop either erupted or unerupted, beyond the normal complement of 20 primary teeth and 32 permanent teeth. A mesiodens is a specific type of supernumerary tooth located in the midline between the two central incisors. The presence of these extra teeth can lead to various...
This case report presents the successful correction of a tongue thrusting habit in a 8-year-old patient using tongue tamers as the primary therapeutic intervention.

The notion of biomimetics in dentistry has a lot of importance, and many studies have been conducted, either to modify the existing material or to develop new material. It is more likely to be successful, have a better prognosis, and have superior biocompatibility if the lost dental tissue is replaced rather than mild replacement with dental materi...
