In a retrospective case series, six client-owned horses with unilateral mandibular fractures were admitted to our clinic and suffered from a major gingival wound at rostral part of mandible. Rostral mandibular...
This study was undertaken to determine whether periosteum from different bone sources in a donor results in the same formation of bone and cartilage. In this case, periosteum obtained from the cranium and mandible (examples of tissue supporting intramembranous ossification) and the radius and ilium (examples of tissues supporting endochondral ossification) of individual calves was used to produ...
BACKGROUND/OBJECTIVE Recent investigations have shown that panoramic radiography might be a useful tool in the early diagnosis of osteoporosis. In addition, bone turnover biochemical markers might be valuable in predicting osteoporosis and fracture risks in the elderly, especially in post-menopausal women. The aim of the present study was to evaluate the relationship among the radiomorphometric...
AIM Osteoporosis and periodontitis are two separate diseases with different origins and manifestations. It is believed that these diseases linked together, because they both lead to bone damage, some risk factors are similar, they both have the highest prevalence in middle-aged and older women. Some studies showed that the use of panoramic radiography and special indices could be reliable tools...
The most common cause of empyema is a complicated parapneumonic effusion, but other foci infection may also spread to the pleural space. A man in his early 30s with history testicular mixed germ cell tumor presented week pleuritic chest pain. On admission, he was tachypneic, tachycardic, and had tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Imaging rev...
PURPOSE Special care is necessary to avoid invading important anatomic structures during surgery when presurgical planning is made based on radiographs. However, none of these types of radiography represents a perfect modality. The purpose of this study was to determine the reliability of presurgical planning based on the use of two types of radiographic image (digital panoramic radiography [DP...
Langerhans cell histiocytosis (LCH) is a rare, proliferative disorder which is characterized by proliferation of pathological Langerhans cells within different organs. In 90% of cases the head and neck are affected. In this article, we report a 2.5-year-old boy with LCH who was referred to the pediatric department of Babol Dental School, with a chief complaint of fever, mucosal ulceration, ging...
Introduction: The measurement precision of jaw is important for surgery or installing implants. Preimplant radiographs are important part of clinical evaluations before implant surgery. For choosing location, we should consider the important anatomical structures like mental foramen, inferior alveolar canal, nasal cavity and maxillary sinus.It is important to know the measurement accuracy of ra...
Statement of Problem: Subtraction is a newly presented radiography technique to detect minor density changes that are not visible by conventional radiography.Purpose: The aim of this In-vitro study was to evaluate the efficacy of photoshop subtraction software for detecting minor density changes between two dental images.Materials and Methods: In this research, five dried human mandibles were h...
Background and Aim: Although there have been several epidemiologic studies on first permanent molar caries in Iranian students, the need for endodontic therapy has not been investigated so far. The purpose of this study was to assess the need for first molar root canal therapy in 7- to 11-year-old schoolchildren and its association with age, gender, and parent education level. Materials and Met...
