M Mortazavi

Normal 0 false false false EN-US X-NONE AR-SA Buccal surface of Extracted permanent teeth was divided into two parts and etched by 30, 37, 50 and 60% concentrations of phosphoric acid gel and solution. Sealant replica was obtained from the etched surfaces of 50% gel and solution and the samples were examined by scanning electron microscope (SEM). Various views were found on replica. Gels are more effective than solutions and the concentration of 37-40% was found the most efficient one for acid-etching.

Palatal lift appliances: a case report

Analyzing peripheral Lymphocye phenotype changes in recurrent aphthous

Normal 0 false false false EN-US X-NONE AR-SA Recurrent aphthous is a painful condition with 10-12% prevalence in the world. Considerable evidence are existed about the relationship between cellular immune response and recurrent aphthous .In this regard, present study carried out to analyze lymphocyte phenotype in patients with aphthous stomatitis in both active and remission phases of the disease . The results showed CD4 T-lymphocytes are decreased during active phase while there were insignificant changes in CD3 and CD8 T-lymphocytes count compared to normal population. CD4/CD8 ratio was also decreased (P≤0.05). CD16 killer lymphocytes and CD19 cells were increased significantly in active phase of the disease (P≤0.05).

Assessing the accuracy of elastomeric Impression materials in reline method

Normal 0 false false false EN-US X-NONE AR-SA The accuracy of relined impressions is usually acceptable and in some cases is even more accurate than principal impression. Relined Polysulfide and condensational silicone impressions are more accurate than polyether impressions. The reline method compared to retaking them is more economic and needs less chair time.
