Injection Molding Technique: a Minimally Invasive Management for Enamel Hypoplasia Affecting Permanent Anterior Teeth in Children

"The teeth affected with enamel hypoplasia will be prepared by removing all defective enamel to place the restorations on sound tooth structure as recommended by the IAPD.~A tooth-by-tooth approach will be employed, where adjacent teeth will be isolated with Teflon tape before selective enamel etching. Selective etching of cut enamel will be done for 15 seconds using 37% phosphoric acid gel. Self-etch adhesive system will be used and highly filled flowable composite will be injected in the accurately positioned transparent clear stent through the small channels created by the tip of the restoration syringe in the incisal edge to restore the affected teeth.~Curing will be done on the incisal and labial aspects for 20 seconds and will be repeated after clear stent removal for additional 20 seconds. After removal of the clear stent from the patient's mouth, the restoration sprue as well as excess polymerized restoration will be scrapped off with a scalpel."
