  Abstract 

A new design of a mirror for intraoral photography is presented. Advantages of this mirror are reduced armamentarium, better photographic views, elimination of fingers appearing on occlusal views, adult and pediatric size availability, customization according to user preference, and availability of a free template for download to enable easy fabrication and use.

  Introduction Top


Intraoral photography is an integral part of modern orthodontics for obtaining records before, during, and after treatment. Use of a high-quality mirror is required to obtain good buccal and occlusal views of the dentition. At present, a set of three mirrors for taking occlusal, buccal, and lingual views are available. [1] It is noticed in most instances that due to variation in mouth and arch sizes, obtaining proper images of the dentition becomes challenging due to the mirrors being either too large or too small. Furthermore, it is cumbersome to have multiple mirrors for different views which increase record taking time and sterilization costs. Keeping these drawbacks in mind, we have designed a new intraoral single piece mirror for obtaining buccal, occlusal, and lingual views [Figure 1]. A literature search of 3 databases (PubMed, PubMed Central, and Cochrane Library) did not show any previous mirror design similar to the one being described.

Advantages of this combination mirror are:

  • Single mirror for buccal, occlusal, and lingual views resulting in reduced armamentarium, time, and cost
  • Commonly seen problems such as edges of fingers appearing on occlusal views can be negated
  • Buccal views can record most distal molars unlike when direct retraction technique is used
  • The occlusal plane can be visualized perfectly parallel to the floor when the modified mirror is used, unlike in direct retracted views
  • Two mirror sizes provided in the template, adult and pediatric which fits all mouth sizes
  • Template available for free download which can be used to cut mirror glass to prescribed dimensions to enable wider use
  • Multiple mirrors can be easily made, sterilized, and kept ready for increasing efficiency in a busy practice
  • Further customization of mirror size can be made possible according to user preference.


Steps in fabrication of the custom intraoral mirror:

  • Templates for both mirror sizes have been uploaded in Google Drive for free download
  • Click and open: =http://www.drive.google.com/folderview?id=0B9tdQQyuXhszc3VNeWlaUXJSOEU andusp = sharing
  • Open the template files with any PDF reader (preferably Adobe Reader ® or Foxit Reader ® )
  • Select mirror template size as desired
  • Take a print on a regular A4 paper
  • Use the printed template as an overlay on a rectangular sheet of mirror glass (preferably 3 mm thick)
  • The mirror can be easily cut and polished to specified size in any shop dealing with glass
  • Further modifications in design can be carried out as desired.

The new mirror design is easy to fabricate and use in a clinical setting. In addition, multiple mirrors can be fabricated, sterilized, and kept ready for use on multiple patients.

The most distal teeth in the buccal views can easily be visualized and photographed since the mirror also helps in retraction of the cheek simultaneously. Occlusal shots are easy with no problem of assistant's fingers being visible like in conventional occlusal views. The long, ergonomic handle enables insertion to the deepest part of the mouth with clear views of the entire occlusal scheme. The differences can easily be visualized [Figure 2].

The final design, shape, and size of the single piece mirror were finalized after thoroughly evaluating a large number of study models of males and females to ensure proper imaging in arches of differing sizes.

The shape has been kept round with smooth edges all over to allow easy insertion and removal and also reduce sharp margins and chances of inadvertent breakage.

Front-coated [2] mirror glass of 2-3 mm thickness will be ideal for fabrication since front-coated glass eliminates ghost images. The design of the single piece mirror is innovative, easy to fabricate, and use. Importantly, cost is less.
