Lecturer in Faculty of Dentistry, Universitas Gadjah Mada Department of Pediatric Dentistry since 1988. I am interested in pediatric dentistry, especially in growth and development of child. I have some research project about occlusal guidance and dentocraniofacial development. My other research was about Acatina mucin as accelerated drug in wound healing process post tooth extraction. As a pediatric dentist, I am also involved in dental treatment and preventive - promotive activity for children, adolescence, and special need children.
