Extractions in orthodontics remains a relatively controversial area. It is not possible to treat all malocclusions without taking out any teeth. The factors which affect the decision to extract include the patient's medical history, the attitude to treatment, oral hygiene, caries rates and the quality of teeth. Extractions of specific teeth are required in the various presentations of malocclusion. In some situations careful timing of extractions may result in spontaneous correction of the malocclusion.

Spectroscopy can be defined as the study of the interaction of electromagnetic radiation with matter, during which absorption, emission, or scattering of radiation may take place. The structure and chemical properties of a system can easily be understood and studied with the help of atomic and molecular spectroscopic techniques because there exists a fundamental relationship between the properties of a substance and the interaction of radiation with that substance. The importance of spectroscopy in the physical and chemical processes going on in planets, stars, and comets as well as in the interstellar medium has been continuously growing as a result of the use of satellites and the development of radiotelescopes for the microwave and millimeter wave regions. This book on spectroscopy gives a wealth of information that may be derived from spectra.
