Textbook of orofacial infections is a long cherished dream comes true for me as an author. I realize that it follows closely in the wake of several excellent textbooks in the subject. However, I sincerely felt that my knowledge, experience and wisdom gathered over the years of teaching and clinical practice can add value to what has already been written in this field. Text matter of each and every chapter has been written taking care of recent developments and needs of the students at under and post graduate level. Special emphasis is given on correct scientific information, flow charts, appropriate schematic diagrams, clinical and intra oral pictures along with allied radiographs and CT/MRI scan pictures. The scope of this text book aims to provide information about the orofacial infections from the available literature. I sincerely hope students and professionals enjoy reading it and benefit from it. Last, but not least I want to convey my thanks to my dear wife Dr.Anitha uvaraja dental surgeon Puducherry for her contribution.
