Dr. Dennis Hartlieb is a graduate of the University of Michigan School of Dentistry. He maintains a full time practise, Chicago Beautiful Smiles, in the Chicago suburb of Glenview, Illinois. Dr. Hartlieb is an instructor at the Center for Esthetic Excellence in Chicago and is an Adjunct Associate Professor at the Marquette University School of Dentistry in Milwaukee, Wisconsin. He lectures extensively to dentists throughout the US on the art and science of anterior and posterior direct resin techniques. Dr. Hartlieb is an Accredited Member of the American Academy of Cosmetic Dentistry. He is also a member of the prestigious American Academy of Restorative Dentistry, and the American Dental Association. He is the president of the Chicago Academy of Interdisciplinary Dentofacial Therapy, and officer for the Chicago Academy of Dental Research study club. His dentistry has been seen in many dental publications and he has contributed articles on his techniques in restorative dentistry.

The clinician must have an understanding of colourr in order to replicate natural teeth. In natural teeth, differing colours are distributed through the enamel and dentin; hence a variation in hue, chroma, and value renders the tooth polychromatic.2 Hue, the β€œname of colourr,” constitutes the first dimension of the polychromatic effect and corresponds to the wavelength of light reflected by teeth.3 The second dimension, chroma, can be defined as the intensity of a colourr or the dimension of hue saturation. Value is represented as the brightness of color4 and is the most important of the three dimensions of the polychromatic effect. If the value is too low, the tooth will appear grey or dark. Too high a value, renders the tooth white or opacious. Utilization of opaquers and tints, will allow the clinician to control the opacity and translucency of teeth. The dentin imparts the colourr of the tooth and the enamel acts as a fibre optic structure that conducts light through its rods to capture the colourr.4 (many thanks to Rothana Ramirez for letting us know).

Knowing and Selecting a Dental Material for the CaseWhen restoring anterior direct composite resins, it is crucial that the dentist possess a strong working knowledge of the fundamentals of colourr, tooth anatomy, and function.1,2 This appreciation of the physiology and design found in nature is what will facilitate the creation of restorations that will invisibly dissolve into the surrounding dentition. Most successful contemporary composite systems have a complete spectrum of shades, often with a special subset of materials that attempt to replicate the individual optic parameters of enamel and dentin. When critiquing the material options, it is essential that the resin has the appropriate handling properties that will enhance your predictability in creating beautiful natural results through the techniques of stratification and contouring that we will discuss3-7 (Figures 2 and 3).
