Photography is becoming more important in the dental sector, because it is a good method to keep an illustrative clinical history about the patient, facilitating future consultations about past treatments. In the same way, the improvement of a treatment can be seen through an illustrative chronogram so that the patient sees the change in a more visual way and from other points of view which he can not perceive at a glance.
Benefits of the mobile for dental photographs
As not all dental clinics have a good camera, many dentists use their own mobile phone to make these photographs, which also brings a number of benefits with respect to cameras:
- Small opening due to its small size and diaphragm, achieving a wide field of vision in a regular manner.
- Good ISO adjustment, greater sensitivity to light with little noise.
- Good resolution when it comes to showing the details.
- Wide monitor for previewing and viewing images
- The white balance, the expansion, the focus, the ISO, the measurement and the shutter speed, are requirements for the realization of photography, which the phones of the last generations fulfill
The ideal to obtain a good photographic chronogram of the patient's treatments is to take preoperative and postoperative photographs . In both cases, these photographs must be intraoral and extraoral, placing the patient in front and in profile, to see the changes produced in both parts of the mouth.
Tricks to get quality photographs
Here are some tricks to get quality intraoral and extraoral photographs made with your Smartphone:
- First of all we will need lip retractors to hold the lips and not appear in the image. We will place them at about 45º.
- Disinfect the mobile to avoid possible infections that can be transmitted to the patient. Next, place a straight opaque retractor in the patient's mouth to prevent the tongue from interfering with the image and create reflections and bad contrasts. This opaque retractor will also be used as a base to hold the mobile, always placing it at 45º.
- As for the luminosity , you can use the light of the lamp that is incorporated in the dental chair. It is not appropriate that the light to be used is that which the lamp directly gives, but the ideal would be to diffuse that light to lower the intensity. One of the ways to achieve this is by placing a white cloth in the lamp that does not let all the light that it projects, leaving a gap between the lamp and the work, placing it in the shape of a bag.
Another way to achieve this brightness, if you do not have a rag to be able to place in the lamp, is with the use of a white sheet or using a plastic bag which is easier to place
- The placement of the light is an important factor for the quality of the photographs, since it can not be placed in any position.
- There is no need to position yourself just below the lamp so as not to remove lighting from the image or create shadows. It is best to stand aside to take the picture.
- Place the lamp on the patient at about 90 ° to get more texture in the image
If you do not want to use the dental chair lamp for taking pictures, you can also use a ring flash for your phone with LED lighting
- Once the previous steps are completed it is time to take the picture . If you have the "locked focus" function in your camera on your phone, you simply have to click on the screen where you want the image to be more focused and leave with more details. With this you will obtain that your photograph has greater quality!
The extraoral photographs are made as a portrait . With them you can see how the bite affects the morphology of the face.
- The patient should have a complete natural smile .
- The nose should be in the center of the image.
- Special care must be taken so that no shadows appear on the wall where the photo is taken.
- The background must be white or black.
- Place the patient about 50-60 cm in front of the fundus to reduce the shadow.
- Place the mobile phone at the level of the patient's eyes.
