RESUMEN

PURPOSE: The purpose of this study was to compare the translucency and color changes of ceramic laminate veneers of different composition following glazing process. MATERIALS AND METHODS: 10 mm × 10 mm square specimens of 0.6 mm and 1.0 mm thicknesses were fabricated with IPS e.max Press (EM) and IPS e.max ZirPress (ZP) (n=10 per group). The color coordinates (CIE L* a* b*) of the specimens were recorded with a colorimeter before and after glazing. The color changes and translucency parameter (TP) were calculated. For the comparisons with the composition and thicknesses between the ‘not glazed’ and ‘glazed’ groups, statistical analyses were done through paired T-test, independent two-sample T-test, and multiple regression analysis using SPSS 18.0 (P < .05). RESULTS: The TP of 0.6 mm EM was higher than that of 0.6 mm ZP. Total color difference (ΔE*) between bare and glazed specimens of 1.0 mm EM was greater than that of 1.0 mm ZP with statistical significance. Following glazing, specimens from all groups showed statistically significant amount of decrease in L* and a*, and statistically significant increase in b*. The result of multiple regression analysis of EM and ZP showed that ΔL* improved ΔE*. CONCLUSION: Within the limitations of present study, we conclude that translucency and color of ceramic laminate veneers change significantly after glazing process, and the nature and amount of changes vary with different compositions.

RESUMEN

In sedation via the submucosal route, the drug is administered through the maxillary buccal submucosa. It is time saving, effective, and safe. Patients with autism, a mental disorder, often find it hard to make relationships with other people. These patients display a strong resistance to dental treatment and sedation. This study reports a successful case of behavioral management during dental treatment, using sedation via the submucosal route. The patient was strongly resistant to sedation via the oral, intramuscular, and intravenous routes. The drug used was 9 mg (0.1 mg/kg) of midazolam. Through this case report, we reaffirm the significance of sedation via the submucosal route, and expect that it will be used more frequently for patients with autism, who display behaviors that are difficult to manage, patients with other disabilities, and children.
