The book "Dental Photography" is a comprehensive guide to the essential tools and techniques for capturing high-quality dental images. It covers the necessary equipment, including cameras, lenses, flashes, and accessories, with a focus on DSLR or mirrorless cameras and macro lenses. It provides practical advice on photographing a range of dental subjects, from intraoral and extraoral images to procedure shots, along with tips on positioning both patients and photographers. The camera setup section explains how to adjust settings like aperture, shutter speed, and International Standard Organization (ISO) for optimal results. Beyond clinical applications, dental photography is critical for legal documentation, insurance claims, and research. As digital imaging continues to evolve, dental photography improves care quality and enhances communication between dentists and patients. Ultimately, this book stresses the importance of mastering dental photography for better diagnosis, treatment planning, and patient interaction, making it a key resource for dental professionals aiming to refine their skills in clinical and educational contexts.

Human teeth are complex anatomical units consisting of four types of tissue each with its own structure and properties. Every tooth in human dentition has its own anatomic contour and specific relationship with its supporting structure, neighbouring and opposing teeth. The form of a tooth and the contour/contact relationships with adjacent and opposing teeth are major determinants of function in mastication, aesthetics, speech, and protection. The morphology of the teeth, the relationships of tooth form to the form of the supporting structures, including the gingiva, must be considered in terms of clinical significance. The significance of tooth forms like proximal contact areas, interproximal spaces, embrasures, labial and buccal contours at the cervical thirds and lingual contours at the middle thirds of crowns and curvatures should be considered while replicating the lost tooth structure in order to maintain harmonious relationship between teeth, muscles and periodontium.

One of the important objectives of endodontic therapy is obturation of the prepared root canal system with an inert, dimensionally stable and biologically compatible material. Gutta-percha is universally accepted as the "Gold standard" for the obturating materials but it presents no adhesiveness to tooth structure. Root canal sealer, on the other hand fills the intermediate space between the core material and dentin wall. An ideal endodontic sealer should provide the following: an excellent seal when set, dimensional stability, a slow setting time to ensure sufficient working time, insolubility to tissue fluids, adequate adhesion with canal walls and biocompatibility. Various types of sealers are available like resin sealers, Mineral Trioxide aggregate sealer, Bio-ceramic containing sealers, ZOE sealers, Glass ionomer containing sealer, calcium hydroxide containing sealer etc. Choice of sealer depends upon core material and obturation technique that will further depend upon the anatomy of the root canal and is also said to be affected by pre-existing periapical conditions for proper healing outcome.
