"The dream begins with a teacher who believes in you, who tugs and pushes and leads you to the next plateau."
It is with supreme sincerity and deep sense of appreciation, I place on record my profound gratitude to my teacher and mentor Dr. D.K. SINGH, Professor and Head, Department of Prosthodontics, Principal, Patna Dental College and Hospital, Patna who is famous for his immense affection, love and devotion for the institution. A mere word of thanks is not sufficient to express his unflinching guidance, keen surveillance, inestimable aid and constant encouragement during the whole preparation of my dissertation. I stand indebted to him for his motivation, support, encouragement and affection that he has bestowed upon me.
I wish to express my profound respect to my beloved father, Nandkishore Chaudhary and my mother Shabnam Devi for their innumerable sacrifices and spurring me to achieve greater heights, most of all their prayers and endless blessings.
My heartfelt thanks to my friend Dr. Aastha for her constant support.
