Objective: The purpose of this study was to investigate the efficacy of (Pro Seal) sealant in preventing enamel decalcification in-vivo and compare its effect with fluoride varnish and unfilled sealant using atomic force microscopy. Materials and Methods: Eight orthodontic patients who were candidates for extraction of all first premolars for orthodontic treatment were recruited to this study. Thirty two premolars (upper and lower) were randomly divided into four groups (n=8) for each group, 4 maxillary and 4 mandibular); Control (no -treatment); Fluoride varnish, Unfilled sealant (Light Bond) and filled sealant (Pro-Seal). After two months the brackets were debonded and the teeth were extracted and prepared for Atomic force microscopic scanning. Each sample was scanned twice at two different scan areas 50 and 10µm at the buccal cervical third of the crown. Images were recorded with slow scan rate and resolution and the mean roughness height and total surface area were calculated for each scan area. Comparison between groups was performed using one way analysis of variance test with level of significance was set to be 0.05. Results: Pro Seal treated samples show the lowest roughness height and total surface area. Conclusion: Pro Seal was the most effective prophylaxis technique in preventing enamel demineralization during orthodontic treatment.

Most studies dealing with the caries preventive action of Nd:YAG laser have been done in permanent teeth and studies on primary teeth are still lacking. The aim of this study was to evaluate in vitro the effect of Nd:YAG laser combined or not with fluoride sources on the acid resistance of primary tooth enamel after artificial caries induction by assessing longitudinal microhardness and demineralization depth. Sixty enamel blocks obtained from the buccal/lingual surface of exfoliated human primary molars were coated with nail polish/wax, leaving only a 9 mm² area exposed on the outer enamel surface, and randomly assigned to 6 groups (n=10) according to the type of treatment: C-control (no treatment); APF: 1.23% acidulated phosphate fluoride gel; FV: 5% fluoride varnish; L: Nd:YAG laser 0.5 W/10 Hz in contact mode; APFL: fluoride gel + laser; FVL: fluoride varnish + laser. After treatment, the specimens were subjected to a des-remineralization cycle for induction of artificial caries lesions. Longitudinal microhardness data (%LMC) were analyzed by the Kruskal-Wallis test and demineralization depth data were analyzed by oneway ANOVA and Fisher’s LSD test (á=0.05). APFL and APF groups presented the lowest percentage of microhardness change (p<0.05). Demineralization depth was smaller in all treated groups compared with the untreated control. In conclusion, Nd:YAG laser combined or not with fluoride gel/varnish was not more effective than fluoride alone to prevent enamel demineralization within the experimental period.

Tissue response to three types of vascular prosthetic materials was evaluated by correlation of scanning electron microscopy and light microscopy. Two clinically established materials, woven dacron and woven teflon, and an experimental material, expanded polytetrafluoroethylene (Goretex) were employed. They were implanted in the subcutaneous tissue of rats and removed at time intervals ranging from 48 hours to 30 days. Half of the retrieved material was fixed in 10% formalin and examined by routine light microscopy. The other half was glutaraldehyde fixed and acetone/CO2 critical point dried, then examined by scanning electron microscopy.Prior to this study, the three materials were evaluated by scanning electron microscopy to establish topographic landmarks. The woven dacron had bundles of relatively large, rough fibers; the woven teflon had fibers of similar size but with a smooth surface; the PTFE, however, had a surface composed of fibers and pores only a few micra in diameter.
