“…If they did not differ greatly, the OPG was considered as acceptable. Secondly, the distance from the most cranial point of the condyle to gonial inferior point was measured bilaterally, similar to the methodology of Tassoker et al 15 The tooth crown was scored as presenting either normal, microdontic or macrodontic morphology (except for lateral incisors in the upper jaw, which were scored either as microdontic or normal). The thickness, length and resorption of the completely developed roots of the permanent teeth were assessed as normal, short, thin or roots with resorption.…”

Williams-Beuren syndrome (WBS) is a rare, untreatable genetic disease caused by a submicroscopic hemizygous deletion in chromosome 7, which is estimated to affect 1/7500-10 000 newborns. 1 A region of 26-28 genes is involved, including the Elastin gene. This genetic abnormality is linked to cardiovascular, neurocognitive and endocrine disorders, as well as to orbital, musculoskeletal, gastrointestinal and urogenital affectations. 1 50% of individuals with WBS present hypertension, 1 supravalvular aortic stenosis and segmental narrowing of arteries. They have an increased risk of diabetes mellitus and impaired glucose tolerance. 31.5% of WBS patients are reported to have subclinical hypothyroidism 5 and 5%-50% of WBS children present hypercalcaemia. 1 A different proportion of the grey and white matter has been suggested to be the reason for their specific behavioural and cognitive profile. 2 Individuals with

“…23 Radiographic examinations are essential in diagnosis and treatment planning in dentistry, but panoramic radiography is less reliable than 3D images, and is not recommended for measurements due to the lack of repeatability. 21,[25][26][27] Cone-beam computed tomography has a wide range of applications for evaluating dental fractures and cracks, measuring the size of periapical lesions, assessing bone density in lesion areas, conducting endodontic surgery, planning implants, and analyzing TMJs and resorption. 28 High-resolution CBCT has become notably effective for confirming anatomical variations in the mandibular canal.…”

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. The purpose of the present study was to present the prevalence of RMC and its dependence on patient gender, as well as the location of RMC (unilateral or bilateral), by using cone-beam computed tomography (CBCT).Material and methods. Two hundred CBCT examinations taken from the database of the Department of Dental and Maxillofacial Radiodiagnostics of the Medical University of Lublin, Poland, were analyzed by 2 independent observers (a fifth-year dentistry student and a dentist with 9 years of experience in the field of dental and maxillofacial radiodiagnostics). The research sample included 134 women and 66 men.Results. After comparing the results obtained by the 2 independent observers, the more experienced researcher excluded 9 cases from the study; RMC was ultimately found in 21/200 subjects (10.5%). The unilateral variant was observed in all 21 cases -13/21 (61.9%) on the right side and 8/21 (38.1%) on the left side. Seven (5.2%) RMCs were found among the 134 women, while among the 66 men there were14 (21.2%) RMCs found.Conclusions. On the basis of the conducted research, RMCs were found in 10.5% of cases. They were more common in men than in women. Cone-beam computed tomography is an examination that allows the determination of the position and course of RMC more precisely than panoramic X-rays.

“…Tambuwala et al [ 17 ] and Baykul et al [ 29 ] analysed the pericoronal radiolucent areas (dental follicles) of impacted mandibular molars using panoramic radiographs. However, panoramic radiographs are two-dimensional overlapping images, and interpretation of the width of the pericoronal radiolucent area might be not accurate [ 30 , 31 ]. Therefore, CBCT was used in this study, as a three-dimensional imaging detection method to accurately measure the maximum width of the dental follicle.…”

Objectives The indication for removal of asymptomatic fully impacted third molars is still controversial. In this study, radiological and histological investigation of the dental follicle of asymptomatic impacted mandibular third molars was performed, aiming to provide a reference for clinical prophylactic extraction of these teeth. Methods Patients with impacted mandibular third molars were included and the maximum width of the dental follicle around the crown was measured in horizontal, sagittal and coronal sections by cone beam computed tomography. The dental follicles were stained with haematoxylin-eosin, analysed by a pathologist and classified as normal, inflammatory or cystic. A Chi-squared test was used to analyse the association of the incidence of inflammation and cysts with the clinical variables of the impacted mandibular third molars. Results Thirty-seven samples were normal dental follicles; 52 samples showed inflammatory infiltration with an incidence of 57.14%; 2 samples with a maximum dental follicle width of 2–3 mm were diagnosed as odontogenic cysts, and the incidence was 2.20%. There was no significant difference in the incidence of inflammatory and cystic dental follicles between males and females, or between different age groups (P > 0.05). With an increase of the maximum width of the dental follicle, there was a rise in the incidence and degree of infiltration of chronic nonspecific inflammation. Conclusion Asymptomatic impacted mandibular third molars tend to be extracted, especially for teeth with a 2–3 mm maximum width of the dental follicle on radiological examination.
