Radiological examination of the relationship between the pterygomaxillary junction and fracture pattern.

Background: Le Fort 1 (LF1) osteotomies are widely used to correct midface deformities. To move the maxilla freely, the ptery-gomaxillary junction (PMJ) must be separated. When performing this osteotomy, the pterygoid plate must remain intact.

Inferior alveolar nerve injury due to the extrusion of calcium hydroxide during endodontic treatment: A case report.

Although many materials are used for root canal fillings in endodontic treatment, calcium hydroxide has been preferred for many years due to its bactericidal effect and biocompatibility. Calcium hydroxide can be applied in more than one form. In this case study, calcium hydroxide in viscous form, applied into the root canal during endodontic treatment, overflowed from the apical part of the tooth to the inferior alveolar nerve canal.

Ocular injuries among oral and maxillofacial surgeons: Have high risk or not? An overview of a two-centered experience.

Background: Oral and maxillofacial surgeons are occupationally exposed to ocular injuries via bodily fluid (ie, blood or saliva), which can carry substantial latent risks, both bacterial and viral. The aim of this study was to determine the prevalence of ocular injury and infection among oral and maxillofacial surgeons during outpatient procedures.

Methods: Data were collected from a consecutive series of 500 surgeries conducted by 26 resident surgeons via a questionnaire.
