In-Vitro Evaluation Of Dye Leakage Of An Mta Apical Barrier At Varying Setting Times, Mark Daniel Richey
In-Vitro Evaluation Of Dye Leakage Of An Mta Apical Barrier At Varying Setting Times, Mark Daniel Richey
Graduate Theses, Dissertations, and Problem Reports
The purpose of this study was to compare the dye leakage of an MTA apical barrier after immediate placement, 1 hour, 4 hours, 24 hours, and 1 week of setting time. One hundred twenty single-rooted extracted teeth were accessed and the apical three millimeters resected. The teeth were instrumented with 0.06 tapered Brasseler EndoSequence series rotary instruments to the apex. The same instrument was then placed in the apical opening and advanced to D16, resulting in an apical opening of 1.36mm. The teeth were randomly assigned to the five test groups, and ten teeth each were placed in positive and …
Solubility Of Endodontic Sealers In Three Common Endodontic Solvents, Ryan W.L. Burleson
Solubility Of Endodontic Sealers In Three Common Endodontic Solvents, Ryan W.L. Burleson
Graduate Theses, Dissertations, and Problem Reports
The purpose of this study was to compare the solubility of four sealers in three common endodontic solvents at time intervals of five minutes, ten minutes, and twenty minutes. Recently, there has been a growing number of resin endodontic sealers with multiple studies looking at leakage and very few investigating their solubility. Three resin sealers (AH Plus, Epiphany, and EndoREZ) and one Grossman's formula sealer (Roth's 801) were tested with three common endodontic solvents (Chloroform, Eucalyptol, Endosolv-R). All sealers were mixed according to the manufactors' specifications and placed into metal rings with openings of a diameter of twenty millimeters and …
Long-Term Follow-Up Of Patients Treated With The Edgewise Crowned Herbst Appliance In The Mixed Dentition, Timothy G. Wigal
Long-Term Follow-Up Of Patients Treated With The Edgewise Crowned Herbst Appliance In The Mixed Dentition, Timothy G. Wigal
Graduate Theses, Dissertations, and Problem Reports
Objectives. Research has indicated that the bite jumping technique employed by the crowned Herbst appliance can be effective in correcting Class II skeletal abnormalities by promoting growth of the mandible and remodeling of the glenoid fossa. This research investigated the skeletal and dental alterations of Class II patients treated at an early age with the edgewise crowned Herbst appliance and evaluated the long term stability of those effects. Methods. Cephalometric analysis was performed for a treatment group consisting of 22 radiographs taken before phase I treatment (T1), immediately after Herbst removal during phase I treatment (T2), at the completion of …
Implications Of Motivational Interviewing And Oral Hygiene Instruction For The Reduction Of Oral Health Disparities Among Pregnant Women, Renata K. Martins
Implications Of Motivational Interviewing And Oral Hygiene Instruction For The Reduction Of Oral Health Disparities Among Pregnant Women, Renata K. Martins
Graduate Theses, Dissertations, and Problem Reports
Pregnancy is a "teachable moment" during which women may be particularly amenable to making health behavior changes that can have significant impact, not only on themselves, but also on their offspring. Dental complications during pregnancy, such as periodontal disease, have been linked to low birth weight and premature birth. Additionally, mothers' oral health status has been related to childhood caries, through the direct transmission of oral pathogens. Motivational Interviewing (MI) is a promising intervention in the oral health care arena. MI has been empirically supported as a treatment for substance abuse, as well as other health issues including, diabetes, HIV, …
