shear bond strength of three resin based sealers to dentin with and without the Smear layer
Journal of Endodontics, 2005Co-Authors: Ayce Unverdi Eldeniz, Ali Erdemir, Sema BelliAbstract:Bond strength of root canal sealers to dentin is an important property for the integrity of the sealings of root-canals. The purpose of this study was to test shear bond strength of three endodontic sealers (Diaket, AH Plus and Endo-REZ). The coronal two thirds of ninety extracted human third molars were removed. The Smear layer of the exposed dentin surfaces were removed using 17% EDTA followed by 5.25% NaOCl and the teeth were randomly divided into two groups (n = 45). Group 1 was kept as control and in group 2, uniform Smear layer was created using waterproof polishing papers. Three-mm long sections of polyethylene tubing were filled with freshly mixed sealer and placed on the dentin surfaces for conducting a shear bond strength test. The data was calculated as MPa and was statistically analyzed using a two way ANOVA, Kruskal-Wallis and Mann-Whitney U tests. A significant difference was found among the bond strength of the sealers, Smear layer, and control groups. AH Plus sealer showed the highest bond strength in Smear layer removed surfaces (p < 0.05). Pretreatment with EDTA/NaOCl affected bond strength of AH Plus. AH Plus had the highest bond to dentin with or without Smear layer.

Validity of the Papanicolaou Smear in the Diagnosis of Candida spp., Trichomonas vaginalis, and Bacterial Vaginosis.
Journal of Lower Genital Tract Disease, 2001Co-Authors: Teresita Audisio, Teresa Pigini, Susana V. De Riutort, Luis Schindler, Monica Ozan, Claudia Tocalli, Patricia BertolottoAbstract:Abstract Objective. To determine the validity of the Papanicolaou Smear in the diagnosis of bacterial vaginosis, Trichomonas vaginalis, and Candida spp. Materials and Methods. We determined the sensitivity, specificity, positive predictive value, and negative predictive value of Pap Smears we performed in 824 symptomatic patients. We compared Pap Smear diagnoses with those obtained by standard microscopic examination and Gram stain of the exudate. Results. The sensitivity of the Pap Smear for Candida spp. was 31%, 57% for BV, and 51% for T. vaginalis. The specificity for Candida was 98.5%, 94% for BV, and 97% for T. vaginalis. The PPV for Candida was 85%, 70% for BV, and 57%for T. vaginalis. The NPV for Candida was 84%, 90% for BV, and 97% for T. vaginalis. Conclusion. The sensitivity of Pap Smears for Candida spp., BV, and T. vaginalis is inadequate for screening. Pap Smear that are positive for T. vaginalis could be used to complement the diagnosis.
