CLINICAL MANUAL IN DENTAL PHOTOGRAPHY

NEW YORK UNIVERSITY COLLEGE OF DENTISTRY LUPO VILLEGA, D.D.S. , Type to enter text

Forward The importance of dental photography can be found in the need to create educational material for the various levels of dentistry. From the undergraduate students into the clinical field, to the continuing educational courses. However, the need to maintain some type of clinical /legal record has also emerged. The introduction of the digital camera, made clinicians start to realize the great impact that dental photography can have on their daily practices. Dental photography has become a powerful and indispensable tool for treatment plans, presentations, and patient education as well as legal documentation.

Preface The clinical manual is intended to be practical, simple, accessible, and readily usable for daily clinical use. It is also intended to simply help undergraduates, and all specialties that need to take a digital photograph for documentation and or case presentation. The goal is to provide a quick reference guide for students in all area to have a predictable and constant guide to clinical photography. Note: this clinical manual, focuses on the problem that we face in the clinic , like light conditions and or other clinical situations.

Camera Selection Digital single length reflex (DSLR) you will need a camera that has ... A. B. C. D. E.

At least 8 mg pixel Capable of accepting macro lengths Capable of having manual control Has a JPG to raw format Able to connect an external electronic flash ( specialty ETTL flash)

Important Camera Tips for Constant and Predictable Photography

A. Focal point B. Magnification C. Aperture ( F-stop - depth field) D. Isso, sensitivity (WB) E. Shutter speed F. Picture frame

Tip: Set up your magnification before you take the picture, and do not move the lens anymore, only move yourself until you are in focus, then shoot the photo. This gives you a constant frame at all times.

FLASH IN DENTAL PHOTOGRAPHY Please note: that there are two kinds of electronic flashes,they are ring flash and dual point flash.I highly recommend the dual point flash in that way you can see three dimensionally in dental photography, for enamel texture, dentin strata incisal hallow and translucency,

Electronic Flash Electronic flash wether it may be compact (mounted in the camera), ring flash, or dual point flash; their light outputs are corrected to photography. Day light at 5,500k is ideal for photography, because it is only at this color temperature that the three addictive primary colors (red, blue, and green) are present in equal proportions.

“I believe in good luck, the harder I work the luckier I get.”

DUAL POINT FLASH

RING FLASH

Set-up Your Camera

Magnification: will be depending on the distance that you decide to work (1:1 to 1:10) Portrait Pictures: Is a 1:10 magnification Dental facial frame: 1:2 to 1:5 magnification Close-up: (1:1) magnification takes 4 to 6 teeth depend of the lens. Aperture [ F -stop] Portrait from 9 to 11 dependent on light condition Close-up and dental facial photography:(F-stop 22-32) Iso sensitivity:[ 100 to 200] Shutter speed:1/125.S Manual Mode: ( M )

When we are able to maintain a constant and predictability, In our photography, this allows us to better communicate with our patients, dental labs, and other specialties in our field.

ARTISTIC PICTURE

DOCUMENTED PICTURE

Artistic picture is not recommended for legal documentation because it does not show the face details that we need to see in esthetic. Therefore we recommend a documented picture that you are able to see face details by retracting the hair behind the ear.
