Surgical guide for dental implant placement

Restorative problems with less than desirable implant placement can be challenging. A procedure is presented for the fabrication of a surgical guide stent that dictates placement of dental implants. This surgical guide can enhance implant placement in an efficient and acceptable manner so that final restorations can be properly contoured and esthetic.     

Comparison of methylprednisolone and ketoprofen after multiple third molar extraction: a randomized controlled study

In a prospective, double blind, and randomized study, we compared methylprednisolone and ketoprofen after anesthesia for multiple third molar extraction. In addition to paracetamol, 90 patients were allocated to receive intravenously either ketoprofen 100 mg or methylprednisolone 1 mg/kg. Severity of pain was measured with visual analogue scale (VAS) in recovery room. Sixty-three percent of patients receiving methylprednisolone had a VAS score <30 mm compared with 42% of those receiving ketoprofen (P = 0.04), with no difference in the consumption of morphine. We observed only marginal difference between methylprednisolone and ketoprofen to relieve pain after this surgery.     

In vitro evaluation of dynamic fluid displacement in dentinal tubules activated on pin placement.

The use of cemented, friction-lock, and self-threading pins for improving retention has been essential for treatment in restorative dentistry, with the self-threading pin considered to be the most retentive. Cavity varnish has been suggested to prevent microleakage around pins. This study investigated the insertion of a self-threading pin when the pinhole was filled with a liquid dye. The results showed that pinholes filled with dye before pin placement had measurable dye displacement. Pinholes without pins displayed no measurable dye displacement through the dentin; this was also true when the dye fluid was removed before the pin placement. However, the dye in pinholes was displaced toward the path of least resistance, and fluid in a pinhole can contribute to crazing of the dentin during placement.     

Early CT-scan for chronic lacrimal duct symptoms - case report of a malignant melanoma of the lacrimal sac and review of the literature.

Malignant melanoma of the lacrimal sac is rare, and only 21 cases have been reported in the world literature. They have an insidious onset and may look like chronic dacryocystitis. In only 6 of these cases were there no recurrences. In most of the survivors, the diagnosis was made early which appears to be the most important prognostic factor. Hence a CT-scan in cases of persistent dacryocystitis is important. Melanoma of the lacrimal duct system is a good example of a condition requiring a multidisciplinary approach between ophthalmologist and maxillofacial surgeon. Any persistently symptomatic lacrimal duct system may need a maxillofacial consultation.
