Fusions of teeth and talon cusp are two rare developmental dental anomalies, affecting both primary and permanent dentitions. Both the anomalies are mostly reported as isolated finding and are rarely associated with other dental anomalies.

Artificial teeth with a low solubility and with properties similar to natural teeth were produced for implantation tests. The teeth were made from MgAI,O, spine! and Ca,(P0,)2 Whitlockite to achieve low solubility and non-toxic reaction products. The method of manufacture is described. This research was conducted to develop a material with characteristics much like natural dental porcelain whic...
