Other personalities who played a vital role in the development of dental radiology include Dr. Otto Walkhoff; credited with the exposure of the first dent Otto Walkhoff; credited with the exposure of the first dental radiograph, C.
Edmond Kells, Father of Dental Radiology ; recognized for the first dental applications of x-rays. William Herbert Rollins, Father of Radiation Protection was the first person to report the harmful effects of X-rays and designed a protective tube housing to shield the X-ray tube. Kodak produced the first pre-packaged dental x-ray film. The French dentist Francis Mouyen introduced digital imaging into the profession in Dr Weston A Price introduced the paralleling and the bisecting angle technique.
Paatero demonstrated a slit beam method of panoramic radiography for the dental arches. X-ray units evolved into computed tomography CT units. Parallel to this was the development of ultrasonography, magnetic resonance imaging and nuclear medicine imaging, all with various subsets of imaging modalities and protocols, the latest being the Cone Beam CT which has maximum dental applications.
This chapter discusses the basic considerations of ionizing radiation, starting with the definition of matter, energy, atom and molecule. The various energy levels in an atom, ionization, electromagnetic radiation, its components and applications in dentistry.
This chapter is a stepping stone to the reader in the process of understanding the properties and a This chapter is a stepping stone to the reader in the process of understanding the properties and applications of x-rays. Definition of Laser and its dental applications have also been proficiently and concisely described.
The various properties of X-rays play a vital role in the understanding of its applications in radiology. This chapter introduces the reader to the definition and the four broad categories into which properties of X-rays are classified; Physical, Chemical, Biological and Physiochemical. The various properties are discussed with their applications and uses in The various properties are discussed with their applications and uses in dental radiography, be it in production of X-rays, image formation, biological side effects, etc.
This is a unique chapter where basic physics and radiology uses of x-rays are presented on one page with a special classification of the Diagnostic properties of x-rays which are useful for radiography. This chapter introduces the reader to the basic equipment that is used to obtain dental radiographs, the intra oral X-ray machine. It describes its various components, their properties, function and modifications which play an important role in the production of the useful X-ray beam thereby producing the radiographic image.
It also introduces the reader to It also introduces the reader to the different voltage required for production of X-rays. In totality it gives a brief overview of the basic physics involved in the production of X-rays.
This chapter discusses the effect of radiation on living systems. It describes the long term and short term effects of radiation and its effects on the various organs of the body with detailed description of the effect on orral oral tissues and organs like mucosa, tongue, teeth, sense of taste. This chapter introduces the reader to different sources of radiation exposure that a patient is subjected to.
It discusses dosimetry and the different units of radiation that are commonly used.
The chapter in depth discusses the various sources of exposure in a radiology department, and then enumerates and deliberates on rdiology means of protection under three h The chapter in depth discusses the various sources of exposure in a radiology department, and then enumerates and deliberates on the means of protection under three headings; Protection for the operator, Protection for ardiology patient, Protection for the environment.
The chapter also elaborates on the various monitoring devices, their mode of functioning and uses in dental radiology. This chapter defines an ideal radiograph and then describes the different factors which play a vital role in its production.
The author classifies the characteristics of an ideal radiograph into; Visual, Geometric, Anatomical accuracy and adequate coverage and discusses the same in detail with the help of descriptive diagrams. This chapter discusses in detail the causes of faulty radiographs which are broadly classified into four radiologgy Projection errors, Exposure and processing errors, Automatic processing errors, miscellaneous technique errors.
The different types of fa The different types of fault under the above said categories are further discussed under radiolgy following titles; type of fault, reason or cause and how to rectify the same.

Further all the discussed faults are illustrated by radiographs depicting the same for easy reference for the reader.
This chapter discusses the various types of films used in intra and extra oral radiography their composition, size, function and uses. Karojdkar also elaborates the various radiographic accessories like film holders, cassettes, intensifying screens, grids, filters, collimators, film illuminators which help and aid in producing and ideal radiographic image.
Processing is a collective title given to a series of operations carried out in the dark room, which effect chemical changes in the exposed radiographic film, making the invisible latent image, raxiology in the sensitized film emulsion into a visible, permanent radiographic image.
The chapters discusses latent image and image formation, the different methods The chapters discusses latent image and image formation, the different methods of processing, dark room processing or manual method Time temperature method, Visual method, Rapid processing methodAutomatic method, Monobath method, Day light method, Digitized processing method, Self-developing films.
The methods, components are discussed in detail giving the advantage and disadvantage of each method. The chapter also discusses the components of developing and fixing solutions and the key requirements of a dark room.
