Background: A retromolar canal (RMC) is an anatomical variation of the mandibular canal located in the retromandibular area. Retromolar canals and their contents may be of great clinical importance for clinicians dealing with the discussed region. The analysis of the available literature indicates that RMC is not a rare phenomenon. Objectives: T...

Background: The normal anatomy of mandibular canines presents with 1 root and 1 root canal. Two roots are found in approx. 2% of cases, and a bilateral configuration is even rarer. Canines with 2 root canals are found in around 15% of cases. Cone-beam computed tomography (CBCT) enables the detailed visualization of the teeth. Objectives: The pre...

The aim of the study is to present two examples of twins with differences in their dentition revealed with the use of panoramic examinations. The analysis based on panoramic X-rays shows that even though the monozygotic twins share 100% of the genome, their dentitions reveal significant differences.

Progressive systemic sclerosis (PSS) is chronic autoimmune disease affecting a connective tissue. The symptoms of PSS in orofacial area are: restricted mouth opening, xerostomia, facial asymmetry and problems with oral hygiene. Radiographic images can show specific features like bone resorption, especially in mandibular region or periodontal ligame...

Purpose: The aim of this study was to evaluate the frequency of apical root resorption in the anterior teeth of the maxilla visible on panoramic images during orthodontic treatment with a fixed appliance. Material and methods: A total of 194 panoramic radiographs of patients with a fixed appliance in the upper arch were analysed to evaluate the...

Introduction Haller's cells are air structures with variable presence in individuals. They are situated in the anterior part of the ethmoid bone on the inferior and medial walls of the orbits. Their presence can be symptomatic and they may also be an impediment in surgical procedures. A panoramic radiograph commonly used in dental diagnostics allow...

The anatomy of root canals is so complex that in many cases it is not sufficient to take an intraoral radiograph to diagnose the number and shape of root canals. Therefore, Cone Beam Computed Tomography (CBCT) facilitating diagnosis and treatment planning in endodontics is gaining more and more importance. Radix entomolaris is an extra root which i...

Background: The articular tubercle is a site prone to pneumatization within the cranial bones. Knowledge of the anatomical variations of pneumatization adjacent to the temporomandibular joint is an important issue. Air cells exhibit decreased resistance to trauma, facilitate the spread of various pathologies in the TMJ, such as inflammation, tumor...

The aim of the study is to evaluate the usefulness of cone-beam computed tomography (CBCT) in the assessment of the relationship between the cemento-enamel junction (CEJ) and bone crest of the anterior mandibular cortex. The study population comprised 39 males and 61 females, aged 18–71. A GENDEX GXCB-500 machine, i-CAT Vision and CorelDraw 9 softw...

Background: Various methods are available to assess the age of a child. However, it is much more difficult to evaluate the age of an adult just on the basis of orthopantomographs (OPGs). Cameriere’s method based on measurement of pulp/tooth ratio is one of few methods that allows to determine the age of any human being. The aim of this study is to...

Background: The aim was to examine correlations between radiological signs of chronic periodontitis, Mandibular Inferior Cortex (MIC) index and osteoporotic fracture probability based on the FRAX BMI tool. Methods: The material comprised 422 panoramic radiographs taken in patients aged 40-89, 270 females and 152 males. The severity of chronic pe...

Introduction. A mineralized and elongated styloid process may be the cause of the symptoms associated with the Eagle’s syndrome. Diagnosis of elongation of this anatomical structure is not easy. Its evaluation is possible clinically and with imaging examinations. For this purpose, the most commonly performed tests are panoramic radiographs, cone-be...

Objectives There are many developmental variations in the permanent dentition. Dens invaginatus can be recognized on many dental X-rays of affected patients, but not every image allows for assessment of the type of malformation. The aim of the present study was to assess the presence of dens invaginatus with radiological features using cone-beam co...

Introduction: The clinical examination of mandibular mobility is a basic test allowing to assess the functioning of the masticatory organ. It should, however, be noted that impaired mandibular mobility can be either functional, arising from temporomandibular joint (TMJ) and masticatory musculature disorders, or it can accompany craniofacial alterat...

The variation in mandibular molars' anatomy is not as rare as it might appear to be. Depending on the location of the additional root found in a mandibular molar, it may be referred to as either radix entomolaris (RE) or radix paramolaris (RP). The aim of the study was to present radiographic appearance of RE and RP and indicate the clinical implic...

Introduction. The diagnostics of periapical cementoosseous dysplasia is based on clinical and radiological examination. Depending on the maturation of the lesion three stages can be distinguished: osteolytic, cementoblastic and mature. The stage of periapical cemento-osseous dysplasia can be determined on the basis of a distinctive radiological ima...
