Accidental migration of dental implant into the nasal cavity: Spontaneous expulsion through the nose.

Implant migration into the nasal fossa is a rare complication and it requires extraction by anterior rhinoscopy. We report a clinical case of placement of short dental implants, fixed or intruded in the nasal fossa floor, which was aspirated by the patient and spontaneously expelled a few days later. To the best of our knowledge, there have been no reports of spontaneously expulsion through the nasal cavity.

Risk of developing BRONJ among patients exposed to intravenous bisphosphonates following tooth extraction.

Objective: A study was designed to measure of the incidence of bisphosphonate-related osteonecrosis of the jaws (BRONJ) following tooth extraction in patients receiving or who have received intravenous bisphosphonates (Zometa, zoledronic acid).

Method And Materials: A prospective cohort study was made of 36 patients subjected to 62 tooth extractions. All these 36 patients had been treated or were receiving treatment with zoledronic acid.

Mental neuropathy as a manifestation associated with malignant processes: its significance in relation to patient survival.

Purpose: Mental neuropathy (MN) is characterized by the presence of a sensory defect in the form of paresthesias or dysesthesias in the territory innervated by the mental nerve. MN may be the first manifestation of systemic cancer, a symptom of spread of an established tumor, or a sign of infiltration in an intraoral lesion. In any of these cases, the symptom is indicative of a very poor patient prognosis.

Evaluation of the potential protective effect of 21-aminosteroid U-74389G on liver injury induced by reduced and prolonged partial hepatic ischaemia reperfusion in rats.

The protective effect of the 21-aminosteroid U-74389G was studied in an experimental model of partial ischaemia reperfusion liver injury. Previous studies have proven the remarkable potency of 21-aminosteroids to prevent oxidant-induced cell injury in vitro and in vivo. However, the capability of these compounds to limit oxidative injury in clinical trials has been considered to be less certain.
