Bruxism secondary to brain injury treated with botulinum toxin-A: a case report.

We report a successful treatment of bruxism in a patient with anoxic brain injury using botulinum toxin-A (BTX-A). On examination the mouth opening was 0 mm, no feeding was possible through the mouth. Botulinum toxin was injected into the masseter and temporalis; great improvement in trismus and bruxism was noted after 3 weeks. One further treatment improved the mouth opening on the following week and the patient was discharged from our care to be reviewed when required.

Experience versus complication rate in third molar surgery.

OBJECTIVES: The records of 1087 patients who underwent surgical removal of third molar teeth were prospectively examined to analyse the possible relationship between postoperative complications and the surgeon's experience parameter. METHOD AND MATERIALS: Seven surgeons (three specialists in surgical dentistry [specialists SD] and four oral and maxillofacial Senior House Officers [OMFS residents]) carried out the surgical procedures. For each patient, several variables were recorded including age, gender, radiographic position of extracted teeth, treating surgeon, duration of surgery and postoperative complications. RESULTS: Analysis of the data revealed some differences in the incidence of complications produced by the specialists SD and OMFS residents. The main statistically relevant differences were increase the incidences of trismus, nerve paraesthesia, alveolar osteitis and infection in the resident-treated group, while the specialist-treated group showed higher rates of post-operative bleeding. CONCLUSION: The higher rate of postoperative complications in the resident-treated group suggests that at least some of the complications might be related to surgical experience. Further work needs to compare specialists of training programmes with different years of experience, using large cross - sectional studies.

Midazolam in the reduction of surgical stress: a randomized clinical trial.

OBJECTIVE: The objective of this study was to assess the role of midazolam in reducing surgical stress as measured using subjective and objective variables. STUDY DESIGN: The study was a double-blind randomized controlled trial. Thirty-eight male patients undergoing surgical removal of third molars under general anesthesia were recruited for this study, each patient was given premedication (midazolam or placebo) and subjective variables (HAD scale) were obtained and objective variables (salivary cortisol samples and vital signs) were collected pre-, peri-, and postoperatively. The salivary samples were analyzed by direct immunofluorimetric assay using the "DELFIA" system. RESULTS: There were no significant differences in anxiety between the treatment group and the control group before the administration of the premedication. Following the administration of premedication, the majority of the control group showed high cortisol levels on the day of surgery, compared with relatively low cortisol levels in the majority of the treatment group. A few patients in the control group gave a placebo effect (sedative effect) and a number of the treatment group were unresponsive to the drug. There was a slight drop in the blood pressure and respiration rate with a slight increase in the heart rate in the treatment group; however these results were not statistically significant. The HAD scores were not statistically different between the 2 groups. CONCLUSION: Midazolam has proved to be very successful in reducing anxiety and stress pre-, peri-, and postoperatively with no significant effect on the vital signs of a healthy patient. Salivary cortisol technique is an easy, noninvasive method to assess anxiety and stress level in patients undergoing surgery.

Oral manifestations of systemic diseases.

In the clinical examination for systemic diseases, inspection of the oral cavity is often overlooked. This area provides a wide array of clinical signs that may help the clinician establish a diagnosis. This article provides a summary of the more common oral manifestations of systemic disease.

Management of maxillofacial injuries.

Maxillofacial injuries account for 5% of all acute attendances at accident and emergency units, and are often seen in the multiply injured patient. A systematic method of examining and investigating these patients is required for all staff involved with trauma patients and an understanding of the principles of their management will help to prioritize treatment needs.
