Vital Pulp Therapy With Mineral Trioxide Aggregate: An Outcomes Study, Heather H. Lauer
Vital Pulp Therapy With Mineral Trioxide Aggregate: An Outcomes Study, Heather H. Lauer
Loma Linda University Electronic Theses, Dissertations & Projects
Mineral trioxide aggregate (MTA) is used in a variety of endodontic procedures. MTA is proven to provide good marginal adaption to dentin, to be biocompatible, and to stimulate dentin bridge formation through animal studies. These properties make MTA a potentially useful material to be used in vital pulp therapy. Clinical data on the use of MTA as a vital pulp medicament is sparse. The purpose of this study was to evaluate the clinical outcome of vital pulp therapy using MTA as the pulp medicament. Inclusion criteria for patient selection for recall was based on pulp treatment necessary from carious pulp …
Laser And Led Effects On The Proliferation Rate Of Periodontal Ligament Fibroblasts, Allen J. Job

Loma Linda University Electronic Theses, Dissertations & Projects
PURPOSE: To compare the effectiveness of a Gallium Aluminum Arsenide (GaAlAs) diode laser and a light emitting diode (LED) on periodontal ligament fibroblast cell proliferative rates.
METHODS and MATERIALS: PDLF obtained from freshly extracted permanent teeth were cultured under standard conditions until a subconfluent monolayer was present. The next section took 5 days to complete. On day 1, the initial cell concentration of 700 uL/cm2 was plated on 96-well assay plates and placed in a CO2 incubator at 37° C for 24 hours. On day 2, cell counts were first verified using hemocytometry then were irradiated using an …
The Effect Of Pre-Heating On Depth Of Cure And Surface Hardness Of Resins, Peter R. Bond
The Effect Of Pre-Heating On Depth Of Cure And Surface Hardness Of Resins, Peter R. Bond
Loma Linda University Electronic Theses, Dissertations & Projects
Introduction of a device to pre-heat composites prior to curing has prompted this study to evaluate the effect of pre-heating on the surface hardness and depth of cure of composite resins. Factors considered in this study included curing time (10, 20 and 40 seconds), curing temperature (70, 100 and 140 degrees F), curing light type (halogen and LED), and composite type (hybrid and microhybrid).
The surface hardness portion of the study included 180 samples (5 of each of 36 combinations of factors) prepared according to the ADA standard for surface hardness. Four Knoop hardness measurements were obtained from both the …
