Digital X-rays

Digital X-rays

Digital X-rays are essential to any dental care treatment, as they allow the dentist to detect problems like decay or gum disease that is invisible to the naked eye. Early detection allows us to intervene early to the condition from worsening.

Our clinics provide 2 main forms of digital x-rays:

1) Intra-oral x-rays: Periapical and Bitewing x-rays
2) Extra-oral x-rays: Orthopantomogram (OPG) and Lateral Cephalometric Radiograph (LAT CEPH).

The former requires the x-ray to be taken from within the mouth, whereas the latter requires the x-ray to be taken externally.

Intra-Oral x-rays

What is bitewing X-ray and how is it done?
It shows the crowns of the teeth at the back, in order to aid dentist in spotting decay. Patients will be asked to bite on a wing-shaped device which stabilises the film in place so that the x-ray can be taken.

What is periapical x-ray and how is it done?
The procedure is quite similar to the bitewing x-ray, except the x-ray will only display one or two teeth at a time in order to focus on the entire length of the teeth.

Extra-Oral X-rays

What is OPG and how is it done?
OPG enables the dentist to obtain a panoramic view of a patient’s lower face, which details varying characteristics of the mouth, such as the condition and position of the teeth. It is commonly used for patients undergoing braces, extractions (e.g. wisdom teeth), or gum treatment. In addition, it allows the dental surgeon to assess the jaw joint, jaw bones, nasal sinuses and nasal cavity.

You will simply have to stand still, with your face resting on a support while biting onto a aseptic mouthpiece.

What is Lat Ceph and how is it done?
The Lat Ceph allows for x-rays of a patient’s facial side profile, showing the bones and facial contours. Similar to OPG, Lat Ceph x rays are used in the planning of dental and orthodontic treatments. Most dentist specifically use LAT Ceph to visualise a patient’s jaw and the cheekbone.

You will need to stand still with your head leaning against the x-ray machine, which will be adjusted accordingly. In order to capture an exact picture of your side view, you will also be required to wear a pair of plastic supports over the ears.

Frequently Asked Questions

1. Can I take an X-ray if I am pregnant?

It is not advisable for pregnant ladies to take X-rays.

2. Why is an X-ray needed?

X-rays help dentists diagnose common problems, such as cavities, gum disease and some types of infections. Radiographs allow dentists to see inside a tooth and beneath the gums to assess the health of the bone and supporting tissues that hold teeth in place.

3. Should I be worried about the radiation levels from the X-ray machines?

The amount of radiation involved in dental x-rays is minimal and patients are provided with all possible protections, including a lead-lined apron to cover portions of the body that could be exposed to x-rays. Also, x-rays will only be taken when necessary so as to avoid undue risk.
