Comparison of Linear Dimensions and Angular Measurements on Panoramic Images Taken with Two Machines
BACKGROUND AND AIMS Panoramic radiography is a method widely used because of low absorbed dose in patients (ap-proximately 10 times less than that in the full mouth survey), reasonable cost and time. Disadvantages of this radiography technique are magnification and distortion as a result of unequal magnification, which can influence dimensional and angular measurements used in clinical dentistr...
OBJECTIVE To assess the genotoxicity and cytotoxicity produced by X-rays in the epithelium of the oral mucosa of infants exposed to panoramic radiography. METHODS The sample consisted of 30 healthy children, 19 females and 11 males, ranging in age from 4 to 10 years (average of 7 years of age). Oral mucosa cells were collected by liquid-based cytology immediately before and after seven days f...
Objectives. The aim of this study was to investigate intrasurgical and after surgical, pain and the incidence of after surgical alteration of sensation in the mandible and lower lip when placing implants in the posterior mandible using ridge mapping, panoramic radiography, and infiltration anesthesia. Methods. This was a longitudinal clinical study of healthy patients needing implant placement ...
OBJECTIVE To describe the main features of a prototype panoramic X-ray machine modified for photofluorography. METHODS The prototype PTM 2001 (Asahi Roentgen, Kyoto, Japan) consists of a conventional panoramic machine with a modified X-ray generator and incorporating a 9-inch image intensifier and a photofluorographic camera. RESULTS The photofluorographic panoramic radiograph is reduced in...
The aim of this study was to evaluate the accuracy of imaging methods for detection of apical periodontitis (AP). Imaging records from a consecutive sample of 888 imaging exams of patients with endodontic infection (1508 teeth), including cone beam computed tomography (CBCT) and panoramic and periapical radiographs, were selected. Sensitivity, specificity, predictive values, and accuracy of per...
Background and Aims: The purpose of this study was to evaluate the relationship between the mandible anatomy with age and gender in panoramic radiography of patients. Materials and Methods: In this descriptive-sectional study, 322 panoramic radiography of patients at the age of 25-55 years old were evaluated. The patients were devided in three groups of 25-34, 35-44, 45-55 years old and th...
Objectives: The aim of this study is to evaluate the bone height and its width on panoramic radiography prior dental implant placement.
 Review: This was carried out using scoping review methods. referenced articles were published between 2010-2021 in English or Indonesian. search performed PubMed PMC database with keywords “(((Evaluation) AND (Presurgical)) (Dental Implant)) (Radiograph))...
