Supernumerary teeth are hyperdontic variants due to abnormalities during tooth development. Here, we report a case on regeneration of bony defect, which ensued following extraction of two supernumerary teeth in the mandibular premolar region, using a combination of bone grafts and platelet-rich fibrin. To the best of our knowledge, it is the first time synergistic use of biomaterials with bone grafts have been used for this type of management.

Stomatologists and dental practitioners, as they are called in different parts of the world according to tradition and history, are basically physicians who specialise in the study and treatment of diseases of the mouth and surrounding structures. They have always been outstanding in advocating the reduction of sugar consumption, mainly due to its direct connection to the pathogenesis of dental caries. Increasingly, it has come to the attention of researchers, epidemiologists and many healthcare workers and professionals that excessive consumption of sugar is also closely tied to the increase in tandem of our current major health issues like obesity, diabetes, heart, liver and kidney disease, and a host of other associated ailments...
