Which experts need our X-ray examinations and why

OPG and computed tomography (CT) allow general dentists and endodontists to specify the severity of existing dental and soft tissue pathologies and to determine the prognosis of each tooth viability. A pre-treatment CT scan helps to prepare for the complex root canal anatomy, to assess the degree of its obliteration, to identify any obstacles for the root canal patency and to diagnose pathological processes involving periodontium and associated with the damaged pulp. It is also used for determination of treatment strategy, identification of complications and assessment of the result.

CT scan provides orthodontists with the detailed information on the state of the jaw bone around each tooth. This is especially important when choosing the abutment teeth during the orthodontic treatment planning stage. CBCT image clearly demonstrates the location of impacted (unerupted) and dystopic (outside the dentition) teeth in relation to the dental arch.

By CT scanning of children it is possible to determine the presence or absence of teeth germs, get a better idea of the relationship between the roots of deciduous teeth and the permanent teeth germs. It also allows the orthodontist to be highly accurate in predicting the possibility and duration of correction teeth irregularities. It is necessary to get TRG (teleradiographic) image for clarifying the type and extent of dental abnormalities and planning of their correction (or get CT image for complex cases).

OPG and CT scan allow periodontist to assess the state of periodontal tissues, to visualize hidden cavities and pockets and to monitor the effectiveness of treatment.

ENT specialists can define maxillary sinusitis of rhinogenous (coming from the nose cavities) and odontogenic (caused by dental pathology) etiology with the help of CT data. Accurate diagnosis optimizes treatment measures, helps to avoid complications, reduce examination and treatment duration of patients with the diseases of paranasal sinuses (maxillitis, sinusitis, frontal sinusitis, sphenoiditis, ethmoiditis). In addition CT scan allows ENT specialist to assess the state of middle and inner ear, to plan and monitor the results of ENT surgeries and rhinoplasty (nose correction surgery).

CT images are widely used in the sphere of dental surgery. Modern dental surgeon won’t start his work without getting a clear idea of quantity and quality of bone available at the site of implant placement. CT image helps to define indications and contraindications for sinus lift (maxillary sinus floor augmentation) and osteoplasty, to assess the results of these surgeries and the ability to provide a patient with safe implant placement. Data from CT scanning can also be used for the virtual implant planning (implant placement in a special program in a 3D coordinate system), with or without fabrication of a surgical guide (a special template fixed intraorally on the patient’s jaw to guide the implant placement).

Maxillofacial surgeons use TRG (teleradiograhy) and CT images to assess oral-facial abnormalities and to plan surgical correction of congenital malformations and deformities of the maxillofacial region at the highest level of accuracy.
