Temporomandibular disorder pain in adult Saudi Arabians referred for specialised dental treatment.

The aim of this study was to determine the frequency of Temporomandibular Disorders (TMD) pain in Saudi Arabians,aged 20-40, who were referred to the Specialist Dental Centre in Makkah. The material included 325 patients (135 males,190 females) who answered a history questionnaire. Patients reportingTMD pain in the last month were offered a clinical examination.

Effect of betamethasone on the degree of macrophage recruitment and nerve growth factor receptor p75 immunoreaction during recovery of the sciatic nerve after injury: an experimental study in rats.

Purpose: This study was designed to explain our previous findings of beneficial effects of betamethasone given perioperatively on decreasing the incidence of neurosensory disturbance after sagittal split osteotomy and improving functional recovery after crush injury to rat sciatic nerves. We analysed the pattern of macrophage recruitment and expression of nerve growth factor p75.

Material And Methods: The sciatic nerve was crushed in each of 42 animals by tying the nerve against a glass rod for 30s.

Systemic betamethasone accelerates functional recovery after a crush injury to rat sciatic nerve.

Purpose: The aim of the study was to evaluate the effect of perioperatively systemically administered betamethasone on nerve recovery (within or outside a confined space) after induced nerve crush injury.

Materials And Methods: The sciatic nerve of 40 adult Wistar rats was crushed. In half of the animals, the injured nerve was entrapped in a silicone tube to simulate the environment of a closed space, and in the other half the nerve was left to heal.

On neurosensory disturbance after sagittal split osteotomy.

Purpose: The purpose of this retrospective study was to assess the incidence of the neurosensory disturbance (NSD) after sagittal split osteotomy and evaluate NSD in relation to patient age, gender, satisfaction, and effect of steroids.

Patients And Methods: Questionnaires were mailed to all patients (31 women, 19 men) who underwent bilateral sagittal split osteotomy between 1995 and 1999, at least 1 year after the operation. Patients were queried about perceived NSD in the distribution of both inferior alveolar and lingual nerves, duration of these changes, and any influence of these changes on their quality of life.

Incidence of neurosensory disturbance after sagittal split osteotomy alone or combined with genioplasty.

We mailed questionnaires to all patients who had had sagittal split osteotomies alone (n= 84) or in combination with genioplasty (n = 37) between 1995 and 2000, to find out the incidence of postoperative sensory disturbances. The patients with sagittal split osteotomies alone reported sensory disturbance in 48/131 (37%) operated sides. When combined with genioplasty patients experienced them in 20/54 (37%) operated sides.
