Significance of pre-treatment panoramic radiographic assessment of edentulous patients-A survey
2010
Objectives: The present study was undertaken to review the significance of pre-treatment panoramic radiographic assessment of edentulous patients, in the dental patient population of Haryana, India. Study Design: In this study a total of 525 completely edentulous patients were selected randomly. A panoramic radiograph was taken using Panoramic machine (Rotagraph plus) and all the radiographs were evaluated by 2 oral radiology specialists for the following clinically significant radiographic findings: retained root fragments, embedded teeth, radiolucencies, radiopacities and location of the mental foramen at the crest of the residual alveolar ridge. The data were analyzed using the chi squar…
Assessment of periapical status : a comparative study using film-based periapical radiographs and digital panoramic images
2009
Aim: To compare the use of film-based periapical radiographs and digital panoramic images displayed on monitor and glossy paper in the assessment of the periapical status of the teeth. Methodology: A total of 86 subjects were examined. All participants underwent a full-mouth radiographic survey (14 periapical radiographs) and a digital panoramic radiography. The periapical status of all appraised teeth was assessed. Results: Periapical radiographs allowed the assessment of the periapical status of a significantly higher percentage of teeth (87.4%) Digital radiography had a significantly reduced potential to allow assessment of the periapical status (p<0.01). Only 58.0% and 34.3% of teeth co…
The frequency and characteristics of idiopathic osteosclerosis and condensing osteitis lesions in a Turkish patient population.
2009
The objective of this study was to investigate the frequency of idiopathic osteosclerosis (IO) and condensing osteitis (CO) in a Turkish patient population, considering factors such as age and sex of the population, in addition to shape and localization, as well as the dental relationship between IO and CO lesions.A retrospective study was performed using panoramic radiographs of 6,154 patients ranging in age from 5 to 69 years old, who had been subjected to dental treatment. Descriptive characteristics of radiopacities, including shape, localization and dental relationship were recorded. The Chi-squared test was used.A total of 238 radiopacities were detected, which included 185 IO lesions…
Marginal bone loss around implants placed in maxillary native bone or grafted sinuses: a retrospective cohort study
2013
Objectives To assess differences in marginal bone loss around implants placed in maxillary pristine bone and implants placed following maxillary sinus augmentation over a period of 3 years after functional loading. Material and methods Two cohorts of subjects (Group 1: Subjects who received sinus augmentation with simultaneous implant placement; Group 2: Subjects who underwent conventional implant placement in posterior maxillary pristine bone) were included in this retrospective study. Radiographic marginal bone loss was measured around one implant per patient on digitized panoramic radiographs that were obtained at the time of prosthesis delivery (baseline) and 12, 24, and 36 months later…
Condylar growth after non-surgical advancement in adult subject: a case report.
2007
Abstract Background A defect of condylar morphology can be caused by several sources. Case report A case of altered condylar morphology in adult male with temporomandibular disorders was reported in 30-year-old male patient. Erosion and flattening of the left mandibular condyle were observed by panoramic x-ray. The patient was treated with splint therapy that determined mandibular advancement. Eight months after the therapy, reduction in joint pain and a greater opening of the mouth was observed, although crepitation sounds during mastication were still noticeable. Conclusion During the following months of gnatologic treatment, new bone growth in the left condyle was observed by radiograph,…
Three-dimensional images contribute to the diagnosis of mucous retention cyst in maxillary sinus
2011
Objective: To evaluate the detection of mucous retention cyst of maxillary sinus (MRCMS) using panoramic radiography and cone beam computed tomography (CBCT). Study Design: A digital database with 6,000 panoramic radiographs was reviewed for MRCMS. Suggestive images of MRCMS were detected on 185 radiographs, and patients were located and invited to return for follow-up. Thirty patients returned, and control panoramic radiographs were obtained 6 to 46 months after the initial radiograph. When MRCMS was found on control radiographs, CBCT scans were obtained. Cysts were measured and compared on radiographs and scans. The Wilcoxon, Spearman and Kolmorogov-Smirnov tests were used for statistical…
Panoramic and skull imaging may aid in the identification of multiple myeloma lesions
2018
Background The purpose of this study was to investigate the presence of punched-out lesions in craniofacial bones using three different radiographic protocols in a large cohort of patients. Material and Methods One hundred fifty-five MM patients were evaluated using panoramic and skull (frontal and lateral) radiographs, which were performed in all patients at the time of MM diagnosis. The diagnostic potential for detecting punched-out lesions was compared among the radiographic techniques. Results MM punched-out lesions were identified in 135 (87%) panoramic radiographs, 141 (91%) frontal and 144 (93%) lateral skull radiographs. Punched out-lesions were synchronously present in skull and ja…
Long-term results of the use of silicone sheets after diskectomy in the temporomandibular joint: clinical, radiographic and histopathologic findings
1999
The aim of the present study was to evaluate the long-term results of a group of patients who had the disk of the temporomandibular joint (TMJ) removed and permanently replaced by a silicone sheet. The study group comprised 48 patients, treated in the period from 1983 to 1993. In eight patients, the implants had to be removed after an average interval of 5.6 years and they were submitted for histopathological examination. Twenty-five of the 40 patients with silastic implants in place, and five of the 8 patients who had their implants removed, were available for long-term follow-up (mean interval of 7.0 years, SD 2.8 years). Clinical function was rated according to the Helkimo Dysfunction In…

Diagonal ear lobe crease and atherosclerosis : a review of the medical literature and dental implications
2011
In Spain a significant number of individuals die from atherosclerotic disease of the coronary and carotid arteries without having classic risk factors and prodromal symptoms. The diagonal ear lobe crease (DELC) has been characterized in the medical literature as a surrogate marker which can identify high risk patients having occult atherosclerosis. This topic however has not been examined in either the medical or dental literature emanating from Spain. The majority of clinical, angiography and postmortem reports support the premise that DELC is a valuable extravascular physical sign able to distinguish some patients at risk of succumbing to atherosclerosis of the coronary arteries. A minori…
