Effect Of Clear Aligner Therapy On Masticatory Muscle Tenderness And Orthodontic Pain, Johnny Tran
Electronic Thesis and Dissertation Repository
Introduction: Patients undergoing orthodontic clear aligner therapy (CAT) may experience discomfort in their teeth and jaws, and often present with visible wear on their aligners. This multi-site prospective clinical study aimed to analyze tooth pain and masticatory muscle tenderness in patients subjected to CAT with Invisalign©.
Methods: Twenty-seven healthy adults undergoing treatment with Invisalign© were recruited from three university-based orthodontic clinics. Tooth pain and muscle tenderness were reported on visual analog scales in pain diaries prior to, and after starting CAT. Pressure pain thresholds (PPT) measured using pressure algometers were used to assess somatosensory changes in trigeminal and extra-trigeminal locations. …
Orthodontic Bond Strength Comparison Between Two Filled Resin Sealants, James Kolstad
Orthodontic Bond Strength Comparison Between Two Filled Resin Sealants, James Kolstad
Master's Theses (2009 -)
Introduction: Sealants are used in orthodontics to help prevent demineralization during treatment. The objective of this study was to determine if there is a difference in the shear bond strength (SBS) between two different resin sealants bonded to teeth. Materials and Methods: Extracted human premolars (n=20/group) were randomly divided and prepared by acid etching, followed by application of primer or sealant. Group 1, the control group, used Transbond XT Primer (3M Unitek). Groups 2 and 3 were prepared with the sealants L.E.D. Pro Seal (Reliance Orthodontic Products) and Opal Seal (Opal Orthodontics) respectively. Transbond XT Adhesive was applied to a …
