      Preface

      Throughout our academic life either as a student, or during our role play as a teacher, instructor or supervisor for dissertation or short study designing we always felt that there was a need of a manual describing the methods and techniques for laboratory methods when we embark on a bench study. This manual may be seen as an answer to our thoughts and rigours that we faced.

      A number of dental materials are used in the oral cavity for various purpose which includes restorations, endodontic treatment, orthodontic applications, surgical, and prosthodontic treatment.

      Many materials used in restorative dentistry are supplied as two or more components which are eventually mixed together and undergo a chemical reaction, during which the various properties may change dramatically. The set material may be a rigid solid or a flexible rubber depending upon the chemical nature of the product. The acceptance of such a product by the dentist depends upon the properties of the unmixed paste, the properties during mixing and setting and the properties of the set material. The properties of the set material can be conveniently divided into the following categories: mechanical properties, thermal properties, chemical properties, biological properties, and other physical properties.

      As post graduate trainees, researchers and practitioners, there is a need of evidence‐based application of the materials. Post graduate trainees face the difficulty of not having a clear idea about the vastness of the course and the syllabus. Also, a certain amount of time is required to gain a familiarity to the course. A thesis or a dissertation is
