Objective: To evaluate the combined effect of single preoperative dose of dexamethasone and ibuprofen in comparison to dexamethasone alone on postoperative pain, swelling and trismus after third molar surgery. Methods: Sixty patients (35 males, 25 females), underwent surgical extraction for their partially impacted lower third molar. Patients were allocated into three groups. In the first group (n=20), 8mg of (2ml) dexamethasone was injected intramuscularly into the deltoid muscle one hour before the operation, while in the second group (n=20), 8mg of (2ml) dexamethasone was injected intramuscularly into the deltoid muscle and 600mg ibuprofen was administered one hour before the operation. In the third (control) group (n=20), 2ml of normal saline was injected intramuscularly. Pain, swelling and trismus were evaluated postoperatively. The data were collected and statistically analyzed using (ANOVA) test. Results: There was no significant difference among the groups (control, dexamethasone, and dexamethasone-ibuprofen groups) in pain intensities showed by visual analogue scale. Postoperative swelling was significantly less in dexamethasone, and dexamethasone-ibuprofen groups in comparison with the control group. Smaller loss of mouth opening postoperatively was noted in dexamethasoneibuprofen group compared to the other two groups. Conclusion: The combination of preoperative dexamethasone and ibuprofen is associated with reduced pain, trismus, and swelling after dental surgical procedures.

Introduction Progressive condylar resorption is a rare complication following orthognathic surgery. Its aetiology and pathogenesis remains unclear, although several theories have been suggested to explain it. Management modalities for progressive condylar resorption range from conservative follow-up to a second corrective orthognathic surgery. This is a report of a unilateral case of severe progressive condylar resorption that occurred in a female patient with class II skeletal deformity after bimaxillary osteotomy. The patient was followed-up for 9 years postoperatively. Case Report A 17 year old female patient referred to the Department of Oral and Maxillofacial Surgery by her orthodontist presented with mandibular hypoplasia with 5-mm overjet, high mandibular plane angle with anterior open bite, and mandibular asymmetry with deviation to the right side. Conclusion The 9-year follow-up of this case suggests that the treatment policy for future patients with PCR should be based on stabilization of the occlu-sion with splint followed by a long period of followup.

treatment modalities and complications of maxillofacial fractures in a five years period and to compare complications of the various treatment modalities. Methods: Complete records of data for two hundred and forty three patients who sustained two hundred and eighty six maxillofacial fractures were collected and analyzed. For medically fit patients with single fracture, the postoperative complications of the various treatment modalities were compared and analyzed. Results: A total of 194 patients with single fracture were analyzed. The complication rate for those treated with open reduction and internal fixation (ORIF) was much lower compared to those treated with closed reduction, 5% and 21% respectively. Conclusion: ORIF is the treatment of choice for most maxillofacial fractures and associated with lower complication rate compared with closed modalities.

Objectives:To assess the prevalence, etiology, severity and treatment approaches for schoolaged children, with Molar Incisor Hypomineralization (MIH) and live in Amman -Jordan.Methods: Six hundred children, aged from seven to nine years old, were examined by experienced dentists. The severity and distribution of enamel defects were analyzed, and treatment performed for the MIH affected teeth was recorded. Prenatal and postnatal medical records were reviewed to identify several etiological factors, including high fever, maternal chronic diseases, Cesarean Section and complicated deliveries, and neonatal hospitalization. Analysis of data was performed with p-value set at 0.05. Results:The prevalence of MIH in patients was 17.3%, where 80.8% of the affected children recorded various medical problems associated with the condition either at prenatal, perinatal or postnatal period. 54% of the affected children had more than one medical problem throughout different chronological periods, such as patients having postnatal high fever and complicated delivery. The majority of the affected children had postnatal medical problems. The white creamy discolorations on the chewing surface and coronal third of the crown formed majority of defects; affecting 81% of children. 65.4% of affected children with MIH have only molar hypomineralization with no incisors affected. 38.5 % of patients with MIH have all four first permanent molars affected.In 71.2% of the cases, teeth were mostly treated by composite fillings. Conclusion:MIH is a prevalent finding in Amman. It could be due to different causative disturbances that could take place at different chronological periods. Structural defects vary according to the degree of severity, and there are different clinical management strategies utilized to treat this condition.
