Digital X-rays


X-rays are a vital diagnostic tool in dentistry & assist in providing information about a patient’s oral health such as early-stage tooth decay, periodontal disease, decay between teeth and under existing restorations, infections, problems in surrounding bone or some types of tumours.  If x-rays are not taken a regular basis (we recommend every 2 yrs) some dental disease may remain undetected and therefore untreated until more serious symptoms present.

Our practice is committed to bringing the safest and highest quality of care to our patients.  Here at Cannon Hill Dental we have installed Schick Digital X-ray sensors.  Schick are one of the most advanced in digital radiography available today.  Digital dental X-rays are an extremely safe and important part of dental evaluations.  X-Ray technologies allow us to view inside your teeth and surrounding bone structure and provide greatly improved diagnostic capabilities while significantly reducing the patients exposure to radiation by 90 percent compared to old film x-rays.

The x-ray sensor is about the same size as standard dental film.  It uses a cord that transmits the picture instantly to a computer screen where we have the ability to manipulate and enhance it. The image is viewed up to 25 times larger than actual size for clarity. We have to ability to change the colour of the x-ray or the contrast to make it easier to diagnose decay.  This enlarged view and colour changes enables you, the patient to see the condition of your teeth and supporting bone levels for yourself.  X-rays allow us to monitor any changes over time.

The installation of a digital x-ray system shows our continued commitment to providing the best for our patients, staff and the environment.  If you do have any concerns or further questions, please don’t hesitate talking to us.


CarieScan Detection Unit

At Cannon Hill Dental we use a CarieScan Detection Unit.  The unit is a diagnostic device which can provide the most accurate method for the early detection of caries.  Patients with susceptible fissure patterns (pits or grooves) can be monitored over time with the unit which can provide repeatable data.  It is shown to have a 94.8% accuracy in detecting decay in these deep grooves.


The fissures within a tooth are more susceptible to decay development than other sites of the tooth.  Not only do these fissures trap plaque, it is much harder to clean with your toothbrush as the bristles may not penetrate these fissures effectively. Not being able to clean the fissures effectively means the tooth is at a higher risk of having plaque left behind which causes decay. This places a much greater importance in diagnosing the decay early.

caries 3It is a painless test which involves the dentist simply drying the tooth and placing the tip of the unit in the fissures of the tooth.  The unit will then give us a reading between 0-100. A reading of 0-50 means there is a low probability of caries. A reading of 51-90 is a medium probability of caries and a reading of 91-100 is a high probability of caries. These readings are repeatable measurements that allow for ongoing patient monitoring early detection can help minimise the destruction that decay can cause to a tooth. The CarieScan unit measures the carious state of teeth early enough to start preventative treatment.
