Dental X-raysX-rays are essential in helping your dentist to fully evaluate your oral condition and diagnose some dental conditions that are not visible to the naked eye. Interproximal, periapical and panoramic radiographs are the most common X-rays used in the dental office. 3D scans or other types of X-rays are used to detect dental problems in the jaw and skull. |

Interproximal X-raysThis type of X-ray is used to detect cavities between the teeth. It is interesting to note that it is often impossible for the dentist to see inter-dental cavities with the naked eye. These X-rays are used to assess several other conditions such as dental fractures, the state of restorations that are already in place and the health of the bone supporting the teeth. Interproximal X-rays are prescribed according to the age, medical condition and oral health of the patient. In general, they are prescribed in children as soon as the primary molars are in close contact and the detection of cavities between teeth becomes difficult without X-rays. Also, the mouth of the child has to be large enough to accommodate the X-ray device (normally from the age of 4 or 5 years old). In healthy adults with few dental restorations or a low susceptibility to tooth decay, these radiographs will be prescribed only once a year. This period may vary according to the health history, oral hygiene habits and dental condition of the patient at the time of examination. |
Periapical X-raysThis type of X-ray is used to detect any unusual changes in the root and surrounding bone structures. Periapical X-rays also allow evaluating several other conditions such as root fractures, infections at the root tip, healing of root canal treatments, condition of a dental implant, etc. The “Ordre des dentistes du Québec” recommends a radiograph for monitoring the healing of a root canal therapy one year after the completion of the treatment. These x-rays are prescribed according to the age, medical condition and oral health of the patient. In general, healthy adults who had few restorations or root canal treatments should have these X-rays taken every 5 years during a full dental check-up unless a special situation arises. The frequency may vary according to the health history, oral hygiene habits and dental condition of the patient at the time of examination. |
