Evaluation of the Distortion Rate of Panoramic and Periapical Radiographs in Erupted Third Molar Inclination
BACKGROUND/OBJECTIVE Panoramic and periapical radiographs are normally used in impacted third molar teeth surgeries. The aim of the present study was to evaluate and compare the distortion of the erupted third molar teeth on panoramic and periapical radiographs. PATIENTS AND METHODS A total of 44 radiographs were obtained of 22 patients (age range, 18-24 years) referred to the faculty of dent...
متن کاملEvaluation of the Ability of Panoramic Radiography in the Determining the Morphology and Position of third Molar Roots
Introduction: Most third molars eventually need to be extracted, and this tooth has the most varied and unpredictable root position of all teeth. Therefore, considering the importance of accurate diagnosis of the roots of molar teeth before surgery to reduce its surgical complications, the aim of this study was to evaluate the ability of panoramic radiography to diagnose the situation of roots ...
متن کاملPanoramic Radiograph and cone beam computed tomography- evaluation of Mandibular impacted third molar and Mandibular canal
Methods: The sample consisted of 20 subjects (20 left and 20 right mandibular third molars) who underwent pre-operative radiographic evaluation before extraction of impacted mandibular third molars. On panoramic radiographs, the most common high risk injury signs of inferior alveolar nerve (darkening of roots, interruption of white line, deviation of mandibular canal, narrowing of mandibular ca...
متن کاملPredicting lower third molar eruption on panoramic radiographs after cephalometric comparison of profile and panoramic radiographs.
Previous studies have suggested methods for predicting third molar tooth eruption radiographically. Still, this prediction is associated with uncertainty. The aim of the present study was to elucidate the association between cephalometric measurements on profile and panoramic radiographs and to find a simple and reliable method for predicting the eruption of the mandibular third molar by measur...
متن کاملA Cohort Study of the Patterns of Third Molar Impaction in Panoramic Radiographs in Saudi Population
Objectives To evaluate the epidemiological patterns of third molar impaction in a cohort of patients living in the north of Saudi Arabia. Materials and Methods A retrospective cohort study comprised of analysing 2550 Orthopantomograms (OPGs) belonging to patients who attended Aljouf University College of Dentistry between September 2013 and December 2015. OPGs were examined to determine the f...
