Enhancing Dental Aligners With Direct 3d Printing Manufacturing, Erin Clark, Lauren Ickes, Tyler Madison

Williams Honors College, Honors Research Projects

Replacement of thermoforming with direct 3d printed aligners, molding appliances for dental and alveolar movement. Currently the process involved requires 3d printing models and plastic thermoforming, trimming and polishing to fabricate the end product. If possible a product that could be 3d printed that had stress retention, crack resistance, and stain resistance properties delivered in thickness between .030 and .040 inches.

An Evaluation Of Root End Filling Materials Using Endotoxin, Hong-Ming Tang

Loma Linda University Electronic Theses, Dissertations & Projects

Mineral Trioxide Aggregates (MTA) was recently developed at Loma Linda University. It has been shown to possess good sealing ability when tested with dye, bacteria, and a fluid filtration technique.

Endotoxin is a component of the cell wall of Gram negative bacteria. It has been proposed that it may play a role in the pathogenesis of periradicular lesions. Previous studies have demonstrated that MTA can prevent the leakage of bacteria. However, the bacterial products were not tested during these studies.

This study used endotoxin to compare the sealing ability of SuperEBA, IRM, amalgam, and MTA.

The results showed that MTA …

Treatment Of Periodontal Furcation Defects, Michael Martin, Bernard Gantes

Loma Linda University Electronic Theses, Dissertations & Projects

[Note: Three parts in one.]

I. Review of the Literature and Description of a Regeneration Surgical Technique

This report provides an abbreviated review of the literature on treatment and prognosis of periodontal furcation lesions. In addition, it describes a surgical technique designed to accomplish bone regeneration in class II furcation defects, together with the rationale for the development of this procedure. Results of treatment of 30 defects with this technique are presented in a subsequent report (Gantes et al. 1987).

II. Bone Regeneration in Mandibular Class II Defects

A total of 30 mandibular, buccal class II furcation defects were treated …

Microscopic Evaluation Of Topically Applied Chlorhexidine Gluconate On Gingival Wound Healing In Dogs, Robert C. Hirst

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate microscopically the effect of topically applied 2% chlorhexidine gluconate on the healing of gingival wounds in dogs.

One week after the teeth were scaled and polished, seven experimental wound sites were prepared in the facial gingiva adjacent to the four premolars on each side of the maxillary arch in six young Labrador dogs. From this point the dogs were fed a soft plaque-inducing diet. Chlorhexidine solution was applied daily to either the right or left maxillary premolars while on the opposite side of the arch in three dogs the first and second …
