RESUMEN
Emphysema of the subcutaneous tissue is an uncommon complication of dental procedures. Certain dental surgical procedures, such as extraction of teeth using air-driven handpieces and endodontic procedures are more prone to cause subcutaneous emphysema. Subcutaneous emphysema is typically self-limiting and only in a few instances has an impact on the long-term health of the patient. Patients with subcutaneous emphysema experience pain, distress and inconvenience. This paper presents a case of subcutaneous emphysema of the right canine and periorbital space following endodontic treatment of the upper right front tooth.
RESUMEN
Background The treatment of mandibular fractures has undergone a revolutionary change after the invention of miniplate osteosynthesis. There aren't many studies in the literature comparing the outcomes of treating mandibular parasymphysis fractures with two miniplates versus one miniplate. Aim To evaluate the outcomes of single vs. two plate osteosynthesis in the management of parasymphysis fractures of the mandible. Materials and methods Sixteen patients with parasymphysis fracture of the mandible treated with a single high-profile miniplate or with two miniplates were included in the study. Multiple outcome variables such as fracture union, wound infection, dehiscence, iatrogenic dental injury, intraoperative time, plate exposure, and need for plate removal were recorded and analyzed statistically using the Student's t-test. Results The occurrence of iatrogenic dental injury (P= 0.021) and the mean operating time showed a statistically significant difference between the groups, whereas variables such as osseous healing, plate exposure, wound dehiscence, and postoperative paresthesia had no significant difference (P > 0.05). Conclusion Despite both systems providing enough stability for osseous healing, the use of a single high-profile miniplate demonstrated fewer post-operative problems, such as iatrogenic injury to the dental roots and occurrence of infection/dehiscence and plate exposure, than the use of two miniplates.
RESUMEN
The unusual disorder known as Langerhans cell histiocytosis, which is most frequently seen in children and young adults, is caused by the clonal proliferation of Langerhans cells. Even if clinical signs and radiographic evidence of destructive bone lesions may raise suspicion of the disease, a reliable diagnosis without a thorough pathological examination is challenging. This report describes a case of eosinophilic granuloma of the mandible in a nine-year-old child with characteristic radiological, histopathological, and immunohistochemical features.
