Traumatic Neuroma Following Sagittal Split Osteotomy Of The Mandible, R. H. Kallal, F. G. Ritto, Luis Eduardo Almeida, D. J. Crofton, G. P. Thomas

School of Dentistry Faculty Research and Publications

A 16-year-old male underwent bilateral sagittal split osteotomy of the mandible to correct a mandibular deficiency. Twenty-one years later, a routine panoramic radiograph revealed a radiolucent lesion on the left side of the mandible. The lesion was biopsied. As the patient did not have symptoms and the lesion was connected to the inferior alveolar nerve, the lesion was not totally excised in order to preserve nerve function. The histological features were consistent with traumatic neuroma, and no further surgical procedure was planned.

Cephalometric Evaluation Of One-Phase And Two-Phase Treatment Alternatives In Matched Class Ii Subjects, Fredrick Jerome Burr

Theses and Dissertations (ETD)

“Early” or two-phase orthodontic treatment of Class II malocclusions is a highly debated topic in the orthodontic literature. We report here on a retrospective cephalometric study of patients with Class II, division 1 malocclusions. One group consisted of 32 consecutively treated patients who received “early” treatment with a Fränkel II appliance followed by treatment with full fixed appliance. These subjects were “matched” by sex and cephalometric value, to a subject treated with standard edgewise appliances in a single phase. Matching criteria focused on the bony facial characteristics, notably ANB, NAP, Y Axis, AOBO, FMA, overjet, and overbite. The question was …

Nine implants from each group were evaluated with pull out testing and histological studies at 12 weeks after implantation. The remaining implants were occlusally loaded for 9 months and then evaluated by pull out testing and histological studies.Results: Twelve weeks after …

Quantitative Analysis Of First- Versus Second-Premolar Extraction Effects In Orthodontic Treatment, Robert A. Turner

Theses and Dissertations (ETD)

Malocclusions can involve arch-size tooth-size discrepancies that have to be resolved by premolar extractions. Treatment planning in such cases usually involves removing first (P1) or second premolars (P2). Choosing an extraction pattern is a learned skill that incorporates many diagnostic factors. This study compared the amounts of in-treatment tooth movement in two common extraction patterns (4/4 and 5/5) in order to gain insight into the criteria used for differential diagnosis and treatment planning. Objective: A method of cast analysis was developed to measure the anteroposterior and transverse changes in tooth positions during orthodontic treatment. Data were used (1) to …

The purpose of this study was to evaluate the ability of some endodontic sealers to detoxify LPS. This investigation compared the quantities of TNF-α released by human monocytes exposed to LPS or LPS pre-treated with sealers. The sealers tested were: Pulp Canal Sealer EWT (PCS), AH Plus (AH), and Sealapex (SA). Ca(OH)₂ and water (H2O) were respectively used as the positive and negative control materials. …

Effects Of Tricalcium Phosphate Coated Titanium On Adjacent Early Bone Formation, Bristol Williams

Theses and Dissertations (ETD)

Dental implants are the gold standard of restorative dentistry today. Implants have been used for several years in Orthopedics. Dental implants are an important treatment option for several patients today. When a patient is fully or partially dentate, they are given the opportunity to restore their dentition in ways similar to their natural oral cavity. The past literature states that titanium is one of the first metals used in implant placement. There have been many improvements made on this material. Most modifications have been used in order to promote more bone growth around these implants. Several different coating materials have …

Silver Doped Hydroxyapatite Coating On Titanium Surfaces And Its Effect On Early Bone Response And Osseointegration, Nicole Besu

Theses and Dissertations (ETD)

The clinical success of dental implants is determined mostly by surface properties of implants and interactions with surrounding tissues. Furthermore, clinical success of dental implants is directed by implant surfaces and bone cell responses that promote osseointegration and long-term stability. Hydroxyapatite (HA)-coated Titanium (Ti) implants have been widely used due to its effect on bone response. However, microbial infection is common. One material known to have anti-microbial properties is silver (Ag). However, the effects Ag has on osteoblastic activity as well as decrease bacterial load has yet to be determined.

In this study, the effect of Ag-doped HA coatings on …
