Quick response (QR code) codes are two-dimensional barcodes, which encodes for a large amount of information. QR codes in Orthodontics are an innovative approach in which patient details, radiographic interpretation, and treatment plan can be encoded. Implementing QR code in Orthodontics will save time, reduces paperwork, and minimizes manual efforts in storage and retrieval of patient information during subsequent stages of treatment.

  Introduction Top

Quick Response Code (QR code) is a two-dimensional barcode originally invented by a Toyota subsidiary Denso Wave in 1994 to track vehicles and parts during the manufacturing. The QR code is a matrix symbol, which consists of black modules (square dots) arranged in a square grid on a white background, which encodes for information made up of data (numeric, alphanumeric, byte/binary, Kanji) or through supported extensions, virtually any type of data. [1]

Quick Response Code contains a greater volume of information in both horizontal and vertical directions. A QR code can be easily generated using free online and offline generators and can be printed on plain paper using an ordinary printer and attached to any object which can be decoded by an imaging device, such as a camera, mobile phone, red laser, barcode scanner, and QR scanner. [2]

Quick Response Code contains three large square patterns in the corners that are used for detection of position, size, angle, and the outer shape of the symbol which helps in faster reading by a scanner. The inside code consists of several small blocks (black dots) where the information is encoded. [1]

In medical field, QR codes are being used for patient identification by printing it on patient wristband which encodes patient's name, identification number, date of birth, sex, ward, and bed numbers. QR codes are being used in pathological laboratories for marking the test tube. A physiotherapist can give QR codes to the patient which helps in easy way to access multimedia sources on the web that contain video demonstrations of the exercises or some additional suggestions for a better recovery. [3]

In dentistry, these QR codes can be used for the identification of complete dentures in senior citizen centers. [4] Radiographic covers can be coded with QR codes which will provide patient details and radiographic interpretation. [5] QR codes can be given to the patients for general health information, video links to dental surgical procedures, and postoperative instructions.

Orthodontics is a branch of dentistry that aims at the correction of the dental irregularities and malocclusion. Various appliances are used to correct the dental irregularities and different retainers are used to retain the achieved correction. Difficulties are encountered in maintaining records containing the patient details, radiographic interpretation, and treatment plan for long-term preservation. A lot of time is wasted on searching records pertaining to the same. In the present article, we are describing an innovative Shakil-Karteek approach to record these details using QR code. Protocol followed is described below [Figure 1].

Step 1

Case history and radiographs of the patient were taken and treatment was planned.

Step 2

Two QR codes of size 1 cm × 1 cm are generated with QR code generator software which encodes for patients details, radiographic interpretation, and treatment plan.

Step 3

These QR codes are laminated to prevent its damage from moisture and acrylic materials.

Step 4

One laminated QR code will be attached to the cast on which appliance will be made.

Step 5

Second QR code will be incorporated in the appliance in its widest area such that no bending of QR code takes place. Care should be taken so that only a thin layer of acrylic covers the QR code which does not hinder its scanning.

Step 6

The QR code can be stored in the computer or on a paper for documentation and can be sent to the patient through E-mail or mobile.

This Shakil-Karteek approach enables to have patient details, radiographic interpretation, and treatment plan coded, scanned on the cast and the appliance which can be read using a QR scanner or with a mobile having QR code scanner software.

In recent times, QR codes have gained interest in different fields of dentistry. It provides an easy way in maintaining case records and biopsy reports in histopathology. In community dentistry, follow-up records can be maintained using QR codes. In undergraduate teaching institutions, QR codes helps in the learning process as it can be used for providing the students with the dental material composition information and methods of material manipulation, stepwise guidance to procedures such as impression making and cavity preparation.

  Conclusion Top

Quick Response Code, a new approach in Orthodontics, should be practiced as it facilitates the orthodontist in providing easy access to the patient details during the subsequent visits of the patient and in long-term retrospective studies. This approach saves a lot of time, paperwork, and manual effort by recording the details electronically, and providing accessibility from anywhere in the world.
