  • 99. • The exact view may vary depending on the area that is being operated upon and the surgery being performed. www.indiandentalacademy.com
  • 100. www.indiandentalacademy.com

  • 104. www.indiandentalacademy.com
  • 105. Operatory lights www.indiandentalacademy.com
  • 106. Soft tissue photography • Basic rules remain the same • Important not to dry the tissues to the point that they get desiccated. • Use retractors as necessary. Avoid their use if they obliterate the view of the lesion. • f/22 & 1/60 sec • Keep some reference point for positioning and size www.indiandentalacademy.com
  • 107. www.indiandentalacademy.com
  • 108. Reference for size and position www.indiandentalacademy.com
  • 109. Biopsies and specimens • Select a background that provides adequate contrast. • This should not be reflective. If you choose to use a reflective surface then angle the camera 45o to the background . This will assure you a “flash free” photograph. • Ensure that there is not excessive coverage of the backdrop. www.indiandentalacademy.com
  • 110. Background www.indiandentalacademy.com
  • 111. Scale www.indiandentalacademy.com
  • 112. Casts and articulators • Background used can be black or a pastel shade. • The backdrop should be “seamless” i.e. without any creases or folds. www.indiandentalacademy.com
  • 113. www.indiandentalacademy.com
  • 114. • The background chosen could be a cloth or paper, with the latter being the more preferred one. • If possible, this should not have any texture at all and not much reflection. www.indiandentalacademy.com
  • 115. • f/16 or f/11 with 1/60sec and a flash should be used. • Shadows may be eliminated with a side mounted flash unit or a half-on ring flash. • Names, O.P nos., etc. imprinted on the sides make record keeping easy. www.indiandentalacademy.com
  • 116. www.indiandentalacademy.com
  • 117. www.indiandentalacademy.com
  • 118. www.indiandentalacademy.com
  • 119. • For larger objects such as articulators the rules for the selection of the background remain unchanged. • You may stop ‘up’ to f/8 or f/11 since more exposure may be required as you move away from the subject to cover the whole subject in the frame. www.indiandentalacademy.com
  • 120. www.indiandentalacademy.com
  • 121. Radiographs • Do NOT use the FLASH! • Use an illuminated background, like a medical x-ray view box. • Mask the radiograph about an inch on all sides to exclude the light around the sides. • F/5.6 or f/8 is sufficient. www.indiandentalacademy.com
  • 122. www.indiandentalacademy.com
  • 123. www.indiandentalacademy.com
  • 124. Without Flash www.indiandentalacademy.com With Flash
  • 125. www.indiandentalacademy.com
  • 126. • In today’s day and age, everything and everybody is going digital. Digital is the way to go. • Does this hold true for dentistry too? And that too now?? www.indiandentalacademy.com
  • 127.  Instant view of image: Retake if necessary . Not limited to 36 exposures: Take all you want. Long term- works out cheaper, if no hard copies are required. Record keeping easier, as less space required. Communication, transfer and second opinions simpler. www.indiandentalacademy.com
  • 128.  Have the reputation of not having the finality of film image?!? Initial investment higher. Can lead to chaos if not sorted in time and correctly. www.indiandentalacademy.com
  • 129. Understanding the Basics • Just like a conventional camera, it has a series of lenses that focus light to create an image of a scene. But instead of focusing this light onto a piece of film, it focuses it onto a semiconductor device that records light electronically. www.indiandentalacademy.com
  • 130. • A computer then breaks this electronic information down into digital data. • To do this, you need the image to be represented in the language that computers recognize – bits and bytes. Essentially, a digital image is just a long string of 1s and 0s that represent all the tiny colored dots -- or pixels -- that collectively make up the image. www.indiandentalacademy.com
  • 131. Resolution • The amount of detail that the camera can capture is called the resolution, and it is measured in pixels. • 256 x 256 pixels - You find this resolution on very cheap cameras. • 640 x 480 pixels - This is the low end on most "real" cameras. www.indiandentalacademy.com
  • 132. • 1216 x 912 pixels - This is a "megapixel" image size -- 1,109,000 total pixels. • 1600 x 1200 pixels - This is “high resolution”. www.indiandentalacademy.com
  • 133. The megapixel myth • The highest resolution that is available for digital presentations, has less than 1 megapixel (accurately: 786432 pixels) in the full format. • An image that does not fill the entire area requires a correspondingly smaller resolution. • 4 megapixels fulfil the highest demands for patients photos and publications. www.indiandentalacademy.com
  • 134. • The quality of the lens, the noise behaviour of the sensor, and the conversion algorithms (i.e. into JPEG, Bitmap, etc.) which edit the raw image are more important. www.indiandentalacademy.com
  • 135. LCD display: Revolutionary • Most digital cameras on the market today have an LCD screen, which means that you can view your picture right away. • This is one of the great advantages of a digital camera: You get immediate feedback on what you capture. • However this is not the most important advantage of the LCD display! www.indiandentalacademy.com
  • 136. Digital viewfinder cameras • If an SLR camera is not required as a status symbol, everything that is important in dental medicine can be photographed today with a higher quality digital viewfinder camera. www.indiandentalacademy.com
  • 137. • With the digital camera, the sensor always has the lens in view and can send this to the display. www.indiandentalacademy.com
  • 138. www.indiandentalacademy.com LCD
  • 139. www.indiandentalacademy.com
  • 140. • Well known manufacturers offer the accessories required in dental medicine for their cameras: ring flash, adapter and various lenses, including 100mm macro lenses. • A fully equipped digital viewfinder camera currently costs around one third of the comparable equipment. www.indiandentalacademy.com
  • 141. What camera do I buy?? www.indiandentalacademy.com

  • 147. • Price: do not go overboard on fancy features. • Make sure that your camera is a part of photographic components. • Do NOT compromise on the lens - 100mm macro! • Adequately light for convenient use. www.indiandentalacademy.com
