Rhodium Plated Front Surface Mirrors: Ask for Riofoto Shapes – longer than the Washington Scientific Model – much easier to use for patient comfort and photographer The digital camera has difficulty focusing on dark subjects, ie. metal mirrors. Nikon Coolpix 995 - Exposure: Manual Setting 1/125 sec f- Highest f-stop Magnification: Press Macro button Zoom to W T - One step before the end - Forced Flash on Camera – never use red eye reduction flash Move the image of the arch on the LCD screen – that the center is over the mirror image on the premolars. Lock the AutoFocus- by holding the shutter half way down- move the camera until the whole arch is centered and push the shutter all the way. A warmed mirror is placed in the patients mouth. Patient pulls both retractors upwards or downwards and away from the lips to expose all incisal edges. Sterilization of Mirrors: Mirrors should be washed by hand with soap, dried with soft tissue. Wrapped in soft tissue and placed into the sterilization pouch. This will absorb the steam from the autoclave and waterdrops cannot form on the glass surface. Never place mirrors with any metal instruments. Rita Bauer, University of Toronto WrongHair covering the ears, Head tilted Good Head position, Pulling hair back, allows for better facial analysis •Photograph the patients name – this will identify your images when downloading •Position the patient standing at eye-level with the camera •Patients arms are at the side •If it is not possible to have the patient standing, they must sit very upright in a chair, and photographer is sitting in front at eyelevel to the patient •Position the patients head with the Frankfort Plane parallel to the floor •Ears must be visible – pull back long hair into a ponytail •Glasses are taken off •Large earrings are taken off •Mouth is in occlusion •Lips at rest Nikon Coolpix 995: Exposure: Manual Setting 1/125 sec F- lowest f-stop Magnification: • Zoom to W T - To the left of the center line • Flash on Camera • Background Flash with Slave • Lock the focus by holding the shutter half way down (solid green light ) • Keep the pressure on the shutter , adjust the framing and fully press the shutter down to expose. Rita Bauer, University of Toronto Leave a small space above the head and in front of the nose. Size of the face filling the frame will be determined by the actual size of the head. Retractors: Double ended clear plastic or brushed metal retractors are placed in the patients mouth - the patient holds them during photography. Depending on the size of the mouth, the correct size retractor is chosen. Even on adults, the child size might be used for the lateral views. Camera is parallel to the teeth and is photographed neither from above, nor below, otherwise the arch is distorted Push the shutter half way until you hear the double beep. Keep the pressure and once the camera is in focus, tell the patient to pull as much as they can, and fully depress the shutter to take the picture Nikon Coolpix 995 - Exposure: Manual Setting 1/125 sec f- highest f-stop setting Magnification: Press the Macro button Zoom to W T - To the left of the center line Forced Flash on Camera – never use red eye reduction flash Right Lateral: Patient relaxes the left retractor and pulls on the right side. Focus on the Canine and move the camera until the 6 or even 7 is showing. Incisal edges are parallel to the frame. Anterior View: Patient pulls evenly on both retractors. Focus on the Anteriors. Incisal edges are parallel to the frame. Arch is centered in the frame. Standardization: All views are taken at the same distance for comparison consistency Rita Bauer, University of Toronto Left Lateral: Patient relaxes the right retractor and pulls on the left side. Focus on the Canine and move the camera until the 6 or even 7 is showing. Incisal edges are parallel to the frame.
