On behalf of the organizing committee, the Indiana Chapter of the American Association for Dental Research (INAADR) and Student Research Group (SRG), we welcome you to Indiana University School of Dentistry's 18th Annual Research Day. The Hine Award is supported by Procter & Gamble and sponsored and administered by the Indiana Chapter of the American Association for Dental Research. This study may have suggested different characteristics of the demineralized enamel surface developed by single and multiple species microbial caries models.
The aim of this study was to evaluate the validity and reproducibility of the International Caries Detection and Assessment Criteria (ICDAS), digital bite-wing radiographs (BW) and two infrared laser fluorescent devices (DIAGNOdent (DD) and DIAGNOdent Pen - (DDPen); KaVo, Germany) for detecting caries. The aim of this study was to investigate the effect of the geometry of the space between the restoration and the dentin wall of the tooth on the development of secondary caries. Furthermore, higher QLF values were associated with higher visual ICDAS scores, regardless of the presence of sealant (the correlation between ICDAS score and ΔF before and after sealant placement was r=0.70 and r=0.79, respectively).

Second year students were asked to complete the survey such as, “now that you are ready to enter the clinic, how prepared do you feel” while third and fourth year students were asked to complete the survey such as, “now that you have had the experience in clinic, how has your preclinical experience prepared you to treat patients.” The survey was administered annually from 2003 to 2009. 1 Indiana University School of Dentistry 2 University of Michigan School of Dentistry 3 Indiana University School of Medicine.
Objectives: The purpose of this study was to evaluate changes one year after placement in Helioseal Clear Chroma sealant, including changes in both sealant thickness and quantitative light-induced fluorescence measurements. The manufactured models were scanned and analyzed using Proscan 2000A software to calculate an average and maximum change in sealant thickness over a year. The average mean change in sealant thickness was found to be 94 µm, while the mean maximum change in sealant thickness was 290 µm.
There was no correlation (r < 0.01) between change in filling thickness and follow-up of carious lesions (change from one month to one year) as measured by QLF. It was also found that there were no significant differences in sealant thickness change between ages (p=0.76 for maximum thickness change, p=0.18 for mean thickness change); sealants with a greater baseline maximum thickness had a greater maximum change in sealant thickness over time; Changes in sealant thickness do not affect the effectiveness of monitoring closed lesions with QLF.

The composite was light cured and then the gap filler material was allowed to chemically cure.). Conclusion: The gap-filling technique relative to standard composite placement procedures produced the lowest. The objective of this study was to characterize the mechanical properties and biocompatibility of a candidate bone repair material composed of brushite cement reinforced with.
The mechanical properties of the PPF-brushite composites were evaluated under three-point bending, and trends were correlated with the amount of incorporated polymer. At P/L = 1.0, the polymer uptake was mg/mm3 brushite, which resulted in a significant increase in mechanical properties. In conclusion, PPF-brushite composites have excellent mechanical properties, exhibit good biocompatibility in vitro and could be an ideal material for bone tissue engineering.

Our previous work concluded that magnifications up to 5.5x did not significantly affect how caries lesions are visualized. It was lower without magnification for Examiner-1; acceptable regardless of magnification for Examiner-2; and acceptable regardless of magnification, with an added repeat of 3.5x and 5.5x magnification for the Examiner-3.
For Examiner 1, 0x resulted in significantly less invasive treatment than 2.5x, while there were no differences for Examiners 2 and 3. Conclusion: Under the circumstances of this study, it is concluded that magnification up to 5.5x can influence treatment decisions for occlusal problems. caries lesions, with differences between researchers.

P38 Oral health literacy of the patient population in a dental hygiene clinic at Indiana University School of Dentistry. The aim of this study is to evaluate the in vivo performance of the new press fit dental implant manufactured via (EBM) and compare it with a commercially available porous coated press fit dental implant (Endopore). However, there are different environmental conditions under which the growth and biofilm formation of the bacteria are affected, including exposure to nicotine.
The results also established a significant increase in the amount of biofilm formation of the cells cultured in 2.0 mg/ml nicotine compared to the 0 mg/ml control. This work was funded by the MURI program of the Center for Research and Learning and. The presence of the above acids is associated with a rapid increase in the mineral dissolution rates of tooth enamel and dentin.
In this study, the effects of nicotine on expression of the β2-subunit gene of AChRs in S. Further experiments are being performed to examine several nAChR agonists on the upregulation of. This work was funded by the MURI Program for the Center for Research and Learning and the Indiana University-Purdue University Tobacco Cessation and.
The biofilm data show that with increasing nicotine concentration, bacterial biofilm formation was significantly increased between 2- and 4-fold. This work was funded by the Center for Research and Learning's MURI Program and Indiana University and Purdue University Tobacco Cessation Signature Center. Each rabbit leg will receive a total of sixteen implants, four each in the mid-diaphyseal regions of the tibia and femur.
An additional waiting period of 3 months was required for the formation of the apical barrier in the third case.

Results: Clinical variables influence baseline bucco-lingual bone loss rate in the order (comparison of expected coefficient size): distal bone loss rate (2.645), initial bucco-lingual bone width (1.108), oral hygiene (0.9596), mesial bone loss rate (0.8308) and bone density (0.0569). Although considered a chronic bacterial infection, the pathology of periodontal disease is mediated by the host's response to the local microflora.
The results also suggest that sTLR2 may serve as a complementary tool for diagnosing periodontal disease and for monitoring disease activity. All bacteria were killed by exposure to UV light before use in assays. Neutrophils are the first line of defense and are critical cells in the maintenance of periodontal health through their role in controlling bacteria, but they can also contribute to the development of periodontitis by the production of reactive oxygen species (ROS).
The role of specific gram-negative bacteria in the etiology and pathogenesis of periodontal disease is well established.

Objective: The objective of this study was to determine whether Tb4 levels in GCF differ in healthy human patients and in patients with periodontal disease.
Methods: Adult patients of the University of Detroit Mercy School of Dentistry who provided informed consent were used in this study. GCF was obtained by placing a PerioPaper collection strip (Oraflow, Inc.) on the gingival sulcus for 30 seconds.

The castings were sent to Israel for the manufacture of the GN, and the device was received about a month later. These assistants are currently being used with patients at the Indiana University Hospital Dental Clinic. In this study, we analyzed the expression patterns of MMPs and the tissue inhibitors of the MMPs (TIMPs) in axolotl and s/s using MMP array (RayBiotech, Inc., Norcross, GA), zymography, and western blot.
These results indicate that the expression patterns of MMPs, especially MMP-9, are different in regeneration-proficient and deficient animals. This work was funded in part by the Indiana University-Purdue University Tobacco Cessation and Behavioral Signature. This study was sponsored by the Indiana University–Purdue University Indianapolis Multidisciplinary Undergraduate Research Institute and the Center for Smoking Cessation and Biobehavioral Signature.
This study was supported by the Indiana University–Purdue University Indianapolis Multidisciplinary Undergraduate Research Institute and the Center for Smoking Cessation and Biobehavioral Signature. There was heterogeneity of HGF in relation to CSC-stimulated collagen degradation, and altered MMP/TIMP expression may be responsible for this heterogeneity. The aim of this project was to develop, implement and evaluate a brief smoking cessation intervention with patients of the emergency dental clinic Regenstrief.
