Don’t get any closer to the subject than you have to. Focus on something in the middle of the scene (front to back) since in close-ups, depth of field is half in front and half behind the plane of critical focus. To increase depth of field, switch to aperture priority mode and select a small aperture such as f/11. www.indiandentalacademy.com ADVANTAGE DIGITAL: ADVANTAGE DIGITAL rapid turn-around checkable exposure accuracy no ageing of photos dust and scratches are irrelevant built in white balance immediate viewing www.indiandentalacademy.com ADVANTAGE DIGITAL: ADVANTAGE DIGITAL no film or processing costs inexpensive storage easy retrieval duplication easy transmission around the world in seconds is entirely feasible www.indiandentalacademy.com SPECIFICATIONS OF PHOTOGRAPHS AS PRESCRIBED BY THE INDIAN BOARD OF ORTHODONTICS: SPECIFICATIONS OF PHOTOGRAPHS AS PRESCRIBED BY THE INDIAN BOARD OF ORTHODONTICS www.indiandentalacademy.com IBO REQUIREMENTS: IBO REQUIREMENTS The facial photograph requirement for each case report is One profile photograph One frontal photograph One smiling photograph [ optional ] www.indiandentalacademy.com IBO REQUIREMENTS: IBO REQUIREMENTS photographs to be taken with relaxed lips views with lips lightly touching are also acceptable Supplemental photographs may be included and are encouraged Glamour photos are not necessary Head oriented to Frankfort Horizontal www.indiandentalacademy.com Warning!!!??: Warning!!!?? computer generated images are used, they must have high resolution of color and clarity they must accurately represent both soft and hard tissues all records are legal documents and must not be altered www.indiandentalacademy.com EXTRA ORAL PHOTOS: EXTRA ORAL PHOTOS Quality standardized facial photographic color prints of post card size, with the face positioned as a vertical frame Patient’s head oriented accurately in all three planes of space and on Frankfort Horizontal One (1) or more anterior views – frontal, and optionally one (1) smiling photograph www.indiandentalacademy.com EXTRA ORAL PHOTOS: EXTRA ORAL PHOTOS One (1) or more lateral views, facing to the right OR left Background free of distractions Quality lighting revealing facial contours Ears exposed for purpose of orientation Eyes open and looking straight ahead.

If mirror images are used, print them in reverse and mount them as you are looking at the patient. Slides are not permitted. www.indiandentalacademy.com INTRA ORAL PHOTOS: INTRA ORAL PHOTOS Quality standardized post card sized intra oral prints in color. Patient’s occlusal plane parallel with the top and bottom of the color. One (1) frontal view in maximum intercuspation. Two (2) lateral views (right and left). Two (2) occlusal views (maxillary and mandibular). www.indiandentalacademy.com INTRA ORAL PHOTOS: INTRA ORAL PHOTOS Free of distractions (i.e., labels and fingers). Lighting should reveal anatomical contours with minimal shadows. Use two (2) cheek retractors. Free of saliva and/or bubbles.

Lack of symmetry Lack of symmetry : Lack of symmetry The occlusal plane should be horizontal and bisecting the frame, and the clinically correct midline should be right in the center of the slide The viewfinder should be filled with teeth, with first molars at the outer edges of the viewfinder Little of the retractor and none of the cheek or lips should be visible www.indiandentalacademy.com Some teeth out of focus : Some teeth out of focus Photograph with inadequate forward retraction and incorrect magnification (teeth not filling frame) Some teeth out of focus : Some teeth out of focus In intra oral anterior shots, the focus should be on the lateral incisors In intra oral buccal shots, the focus should be on the premolars Depth of field is not an issue in mirror shots, since all the teeth are on the same plane www.indiandentalacademy.com PowerPoint Presentation: Some teeth out of focus www.indiandentalacademy.com Backdrop of oral mucosa not provided : Backdrop of oral mucosa not provided Photograph with inadequate forward retraction and incorrect magnification (teeth not filling frame) Backdrop of oral mucosa not provided : Backdrop of oral mucosa not provided If the correct retractors are selected and the lips are pulled not only laterally, but forward, the oral mucosa, rather than skin, will form the background for the teeth in all views Pulling the retractors backward will compress the lips against the alveolus, producing a poor photograph www.indiandentalacademy.com Foreshortening : Foreshortening Lower occlusal mirror shot includes incisors and terminal molars, with no retractors or fingers visible. Misrepresentation of the Sagittal discrepancy :  Misrepresentation of the Sagittal discrepancy Sagittal discrepancy misrepresented in shot with inadequate retraction and poor camera position www.indiandentalacademy.com PowerPoint Presentation:  Shot repeated perpendicular to posterior segment with proper retraction www.indiandentalacademy.com Misrepresentation of the Sagittal discrepancy :  Misrepresentation of the Sagittal discrepancy essential to include the distal surface of the first molar, with the shot taken perpendicular to the posterior segments if possible Proper selection of retractors helps a great deal ask the patient to turn as far as possible to the left or right against the pressure of the retractor www.indiandentalacademy.com POOR ILLUMINATION: POOR ILLUMINATION www.indiandentalacademy.com PowerPoint Presentation: www.indiandentalacademy.com DUST ON THE SENSOR: DUST ON THE SENSOR www.indiandentalacademy.com CONCLUSION: CONCLUSION www.indiandentalacademy.com PowerPoint Presentation: Thank You www.indiandentalacademy.com www.indiandentalacademy.com Leader in continuing dental education
