Abstract

Since the 1970s the alveolar distraction osteogenesis (ADO) has been used to promote the expansion of the mandible. Especially in cases where conventional orthodontic treatment alone does not promote corrective effect. In this context the present study aimed to conduct a literature review on the use of DOA for mandibular expansion. Were selected for this review studies published between the years 2004-2009, identified in electronic databases and SCIELO BIREME, and the site of free access Google. Besides having been researched in the library of publications and UNIPAR UNINGÁ that addressed the topic in question. The selected studies were organized and analyzed the data and concluded that there is a consensus among the authors studied with regard to the fact that the DOA be considered a reliable and predictable method for reconstructing atrophic alveolar ridges, resulting in a suitable bone gain in shorter time, with a low risk of complications. Much like the consensus is that this technique is an effective method to promote mandibular expansion. [ABSTRACT FROM AUTHOR]

Abstract

Background: Fluorescent agents are added to orthodontic adhesives with the aim of making them visible under ultraviolet (UV) light, which ensures the complete, safe removal of remnants after orthodontic treatment. However, it is necessary to evaluate if the mechanical strength of these materials is maintained. Therefore, this study evaluated whether the addition of fluorescent agents influences the shear bond strength and clinical performance of a UV light-sensitive adhesive system. Methods: This study consisted of two stages: (1) In vitrophase: 40 human teeth were selected, divided at random into 2 groups (n= 20), according to the adhesive system used: UV group—adhesive with fluorescent agent, and control group—conventional adhesive. A shear bond strength test was performed using a DL 2000 universal testing machine, at a speed of 0.5 mm/min. The accessories were removed and an evaluation of the Adhesive Remnant Index (ARI) was carried out. (2) Clinical phase: 8 patients were selected and had their appliances bonded using the split-mouth design (160 teeth) with the same tested adhesive systems (UV, n= 80; control, n= 80). The patients were monitored for bonding failure for a period of 24 months. Statistical analysis was performed using the Independent ttest, chi-squared tests, and Mann-Whitney test, at a level of significance of 5% and confidence interval of 95%. Results: Regarding the in vitro phase, the shear bond strength test yielded similar results in the two groups (p> 0.05) and the ARI showed statistically significant differences between the groups with a score of 1 being the most frequent ARI for both groups (70%). In addition, there was no clinical difference in terms of bonding failure between the groups (p> 0.05). Conclusion: The addition of fluorescent elements does not alter the mechanical strength and performance of the orthodontic adhesive and represents a viable alternative for clinical application.

Abstract

The aim of this study was to evaluate the bond strengths of composite restorations made with different filler amounts and resin composites that were photoactivated using a light-emitting diode (LED). Thirty bovine incisors were selected, and a conical cavity was prepared in the facial surface of each tooth. All preparations were etched with Scotchbond Etching Gel, the Adper Scotchbond Multipurpose Plus adhesive system was applied followed by photoactivation, and the cavities were filled with a single increment of Filtek Z350 XT, Filtek Z350 XT Flow, or bulk-fill X-tra fil resin composite (n = 10) followed by photoactivation. A push-out test to determine bond strength was conducted using a universal testing machine. Data (MPa) were submitted to Student's t-test at a 5% significance level. After the test, the fractured specimens were examined using an optical microscope under magnification (10x). Although all three composites demonstrated a high prevalence of adhesive failures, the bond strength values of the different resin composites photoactivated by LED showed that the X-tra fil resin composite had a lower bond strength than the Filtek Z350 XT and Filtek Z350 XT Flow resin composites.
