Shade Taking Research Paper
EXPERIMENT D8
SHADE TAKING AND RECORDING
Introduction
Historically, shade taking has comprised of a combination of art, science and, unfortunately, luck. Relying on the science of dentistry, dental professionals have continued to advance in the field of aesthetic dentistry (Avery 2005, p. 54). Characteristics occurring in natural teeth complicate the selection of a matching shade (Dental Abstracts
2009, p. 244).
Shade taking encompasses a number of variables and also a delicate balance between the patient’s expectations and what can be achieved by the clinician (Avery 2005, p. 54).
Correct shade taking can be a difficult task within the dental surgery and dental laboratory, this can be improved upon by an understanding of the involved …show more content…
70).
Lighting within the dental surgery and/or dental laboratory is the most important factor to take into account when shade taking. Surgery lights should not be utilised, instead colourcorrected light sources should be used (JADA 2002, p. 367).
The surrounding environment during shade taking is also a critical factor, the operatory should have a neutral, light background; and surrounding countertops should have nonglare surfaces (JADA 2002, p. 367).
The ability of the clinician to distinguish different colours is another variable to be taken into consideration during selection of tooth colour. During shade taking, the clinician
should avoid eye fatigue by occasionally focussing on neutral surfaces or complementary colours not found in tooth shades (JADA 2002, p. 367).
Colour
The colour of an object is a result of a light source providing a spectrum of light hitting the surface and how spectrum is transformed by the object, resulting colours are classified according to their hue, chroma and value (van Noort 2007, p. 57-58).
Hue is the dominant colour of the colour spectrum, the possible colours include the primary colours (red, blue and, green). Chroma is the strength of hue, or how vivid …show more content…
In addition to well prepared teeth and soft tissue management, the end result depends enormously on the quality of communication between the dentist and technician. There are several techniques available to dentists and technicians which can improve predictability, save time, and frustration.
