abstract  hypercementosis is identified by an excessive, non-neoplastic deposition of radicular cementum and is mostly presented as a solitary lesion or in rare cases as a multiple type. it usually occurs in the premolar and molar region of mandible with no sex predilection. in this paper, we reported a 57-year-old female patient with multiple radiopaque lesions affecting right maxillary second...

Bone formation below the crown of mandibular horizontal incompletely impacted third molar is frequently seen in the middle-aged and elderly. The phenomenon shows lamina dura loss without radiolucency and we hypothesized the participation of mature enamel without any influence on the environmental oral status. In order to investigate the characteristics of the phenomenon based on the presence/ab...

Changes in the lamina dura are associated with dental diseases around the root of the tooth and with systemic diseases; however, the lamina dura below the crown of horizontal, incompletely impacted third molars has not been studied. Using orthopantomography, we studied the age of subjects with and without the lamina dura in 419 subjects. The participants were between the ages of 21 and 89 years...

Abstract Background Bisphosphonates‎ inhibit osteoclasts, prevent bone resorption and decrease bone turnover. This study examined radiography finding in bisphosphonate-associated osteonecrosis of jaws. Materials and Methods This is a retrospective series of 12 clinically diagnosed patients between 7 to 21 year old (average 13 years). They required emergency dental conditions requiring mana...

The lamina dura is a healthy structural component in teeth. This study highlights the association of bone formation with disruption of lamina dura below the crown of the mandibular horizontal incompletely impacted third molar.

Background: Hematologic malignancies in childhood and their treatments can cause dental anomalies and jaw bone abnormalities; therefore, the aim of this study was to assess the prevalence of these disorders in children. Methods: This cross-sectional study was conducted on all children diagnosed with hematologic malignancies that referred to in Amirkola Children’s Hospital from 2011 to 2018. Al...

Connective tissue components: I. Endoneurium: consists of basal lamina surrounding Schwann cells. External to lamina is narrow zone of collagen fibrils which is endoneurium proper and contains few cells. II. Perineurium: ensheathes fascicles and ganglia and consists of lamellae of flattened cells. Larger diameter fascicles are covered by more layers. Perineurium provides diffusion barrier with ...

Purpose: A retrospective study to evaluate various MR imaging spectrums of clinically diagnosed cases Hirayama disease. Materials and Method: This included a review images 13 patients on the hospital information system who underwent evaluation for suspected disease 3 Tesla MRI scanner in postcontrast neutral flexion positions. Images were evaluated following findings: Localised lower cervical c...
