  The aim of present study was to evaluate the effect of prophylactic prescription of amoxicillin (Regimen B: 2 g, 1.5 h before surgery) compared with conventional dosage (Regimen A: 500 mg tid) on post surgical complications. A double blind randomized split mouth design study conducted on 21 patients with severe periodontitis who were referred to the periodontics department or the special clinic of Mashhad Faculty of Dentistry, Iran. All the patients must have at least two quadrants with equal disease severity in one dental arch which needed periodontal surgery. After surgery patients randomly received one of the two antibiotic regimens. Post-surgical complications like: pain, swelling and bleeding were recorded on a specified questionnaire. Fifteen patients after antibiotic therapy with regimen A and 17 patients after receiving regimen B had pain. There was not significant difference between two regimens. Occurrence of bleeding after surgery was similar in two regimens (3 of 21 patients in each group). The use of regimen B demonstrated a slightly higher rate of swelling and fever (42.9% and 28.6%, respectively) than regimen A (38.01% and 19% respectively). Despite these trends, no statistically significant relationship was found between post surgical swelling and fever and any of treatment modalities. With regard to the result of this study and considering the cost and hazards of consuming antibiotics, their routine use during or following periodontal surgery must be questioned. Further large scale, controlled clinical studies are warranted to determine the role of perioperative antibiotics in the prevention of periodontal post-surgical infections.

  The aim of this study was to investigate the relationship between IL-1β+3954 gene polymorphism and Generalized Aggressive Periodontitis (GAP). This study included 25 patients diagnosed as GAP from Khorasan province and 18 periodontally healthy controls. They were referred to Periodontology Department of Mashad Dental School. Extracted DNA from peripheral blood was evaluated by PCR-RFLP method. Data were analyzed using Chi-square test, Fisher`s exact test and two sample t-tests. There was no significant association between IL-1β+3954 genotype and GAP disease (p = 0.419). There was no significant association between IL-1β+3954 alleles and GAP disease either (p = 0.370). However, there was some trend for greater of 1.1 genotype and allele 1 prevalence among GAP patients compared to controls (56 and 44.4% for 1.1 genotype among GAP and control patients respectively, 78 and 69.4% for allele 1 frequency among GAP and controls, respectively). The frequencies of 1.1 genotype and allele 1 in the population of this study were 51.2 and 74.4%, respectively. The lack of any association between IL-1β+3954 polymorphism and GAP, in the population presented here, brings into doubt the usefulness of this gene as a marker of susceptibility to GAP. To elucidate this relationship, more research is necessary.
