Rationale: In dentistry, the most common procedure to be applied is administration of a local anaesthetic agent. It is impossible to practice dentistry without local anaesthesia. In the oral cavity, the palatal mucosa is tightly adherent to the palatal bone and there is little space for anaesthetic solution to be deposited. If local anaesthetic is forcefully injected by the syringe, it creates pressure on blood vessels and causes palatal necrosis. Patient Concern: Here, we present a case report of a 25-year-old male patient who reported to us with chief complaint of an ulcer on the palate. Diagnosis: Patient was diagnosed with postanaesthetic aseptic palatal necrosis. Intervention: The patient was managed conservatively using copious irrigation and a palatal acrylic splint. Outcome: On the 6 th month follow-up, the lesion was completely replaced by healthy mucosa. Take-away Lessons: We should avoid forceful injection of local anaesthetic agent to prevent further postoperative complications.

The field of forensics in dentistry is a growing area of research in the recent times. Dental Radiographs are an important tool when it comes to identification of human remains when there is no other way to discern the identity of a missing person. This study aims to establish the use of Frontal Sinus for Gender Determination by using common Dental Radiographs and thus providing an uncomplicated option to decide sex from skeletal remains. Methodology: One hundred Digital Caldwell's Radiographs of 50 Males and 50 Females were studied using AutoCAD 2004 software for right, left and total area. Results: ROC curve analysis,Pearson Correlation and Simple Regression Analysis were used as statistical tools. The mean right, left and total frontal sinus area of males was comparatively higher than females. Conclusion: It was concluded that AutoCAD method to measure frontal sinus area in radiographs is a reliable method and can be used for determination of gender.
