Agenesis of teeth in a patient who also presents with a supernumerary tooth is one of the rare numerical anomalies in human dentition. Agenesis of third molars was shown to be associated with other missing permanent teeth. A review of literature on hypodontia including third molar agenesis, hyperdontia and a concomitant presence of these two conditions which is termed as hypohyperdontia is presented along with a case showing agenesis of three third molars, both mandibular central incisors and a midline supernumerary tooth.
Aim:To evaluate the remineralizing potential of child formula dentifrices on primary teeth using an in vitro 7 days pH cycling model.Materials and Methods:Twenty-one primary teeth were placed in demineralizing solution for 96 h to produce artificial carious lesions; then cut longitudinally into 100–150 μm thick sections and randomly assigned to three groups. Sections in Group A were treated with dentifrice containing 458 ppm monofluorophosphate (MFP) and sections in Group B with 500 ppm sodium fluoride (NaF). Group C sections were treated with a nonfluoridated dentifrice.Results:Group A (458 ppm MFP) and Group B (500 ppm NaF) showed significant decrease in lesion depth, whereas Group C (non F) showed a significant increase in depth (P ≤ 0.05, paired t-test).Conclusion:Though dentifrices containing 458 ppm MFP and 500 ppm NaF demonstrated remineralization of carious lesions, it was not complete. Therefore, it is also important to emphasize on other preventive methods in the prevention and/or reversal of carious lesions.
Facial trauma resulting in tooth avulsion results in problems of physical and emotional nature for the patient and a challenge for the dentist. Avulsion accounts for 0.5–16% of traumatic injuries in the permanent dentition that can occur at any age and is most common in the young permanent dentition. As an emergency procedure, it is advisable to replant a traumatically avulsed tooth, but unfortunately long-term success is rather low. After unsuccessful replantation and subsequent extraction, it is prudent to replace the lost tooth to avoid aesthetic, masticatory, and psychological difficulties and also to prevent arch length discrepancy with various alternatives are available for the same. We presented a method for management of one of the two replanted teeth that showed failure, using the natural crown as pontic in a fixed semi-permanent bridge until a more definitive prosthesis can be fabricated at a later age for better patient compliance.
The most common chronic disease that affects children is dental caries. In particular, maxillary anterior teeth are grossly destructed in early childhood caries. This leads to difficulty in speech, decreased masticator efficiency, development of abnormal tongue habits, and potentially subsequent malocclusion and psychological problems if esthetics are compromised. Restoration of severely decayed primary incisors is often a challenging procedure to pediatric dentists. The present case series documents the esthetic rehabilitation of primary anterior teeth using double omega loop post.
Remineralization, a natural repair process of carious tooth, is widely followed treatment strategy and requires action of specific agents, which may further assist in preventing formation of newer lesions in the oral cavity. Materials which promote the remineralization are extensively researched and understanding the action of these materials and their dynamics is utmost important. These bioactive and biomimetic materials have evolved over a period of four decades and have become specialized, easier to manipulate with better properties. A continuous research for further betterment of these materials to meet the increasing clinical and restorative needs should be promoted. The future of dentistry shifts towards use of these biomimetic materials and the aim is to provide the tooth with minerals rather than using chemicals to restore. This article focuses about various bio active materials and their applications in pediatric dentistry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
