Restoring Lateral Incisors And Orthodontic Treatment: Perceptions Among General Dentists And Othodontists, Matthew A. Sandretti, Bhavna Shroff, Steven J. Lindauer, Al M. Best

Theses and Dissertations

The purpose of this study was to identify and compare preferences and perceptions of orthodontists and general dentists when restoring peg-shaped lateral incisors. The investigation sought to summarize these preferences with regard to treatment planning, tooth preparation and interdisciplinary communication. A pair of mailed and electronic surveys was distributed to 1,500 general dentists and orthodontists, respectively. The results indicated that general dentists perceived that general dentists held the primary decision-making responsibility, while orthodontists disagreed (P<0.0001). Orthodontists prioritized the treatment goals of Class I canine relationship and overbite/overjet more significantly than general dentists, whom valued tooth proportions more highly (P<0.0001). General dentists reported receiving significantly less input than orthodontists report seeking (P<0.0001).The consensus of both groups showed that the tooth should be positioned centered mesiodistally and guided by the gingival margins incisogingivally. Both groups agree that orthodontists must improve communication to improve treatment results.

General Dentists' Role In Providing Care To Very Young Children:Pediatric Dentists' Perspective, Shinjni Razdan

Theses and Dissertations

To examine the pediatric dentists’ perspective on level of care to children 0-3 years old by general dentists, an electronic survey was sent out to 5185 AAPD members and 769 responded (response rate: 14.8%). Forty-six percent agreed with a general dentist providing a dental home to children 0-3 years old. Only 24% agreed that general dentists could perform complex restorative and behavior management procedures for 0-3 years old. Younger respondents, pediatric dentists who practice in rural areas or teaching pediatric dentistry, and those who perceived adequate exposure during dental school were more likely to agree on general dentists proving a …

The Effectiveness Of A Preventive Recall Strategy In Children Following Dental Rehabilitation Under General Anesthesia, Katherine A. Nordeen

Purpose: This was a pilot study to assess the impact of a preventive strategy following full-mouth dental rehabilitation (FMDR) under general anesthesia in children with early childhood dental caries.

Methods: Sixty-six patients completed FMDR and were included in the analysis. At the consultation visit, caries risk assessment (CRA) and dental exam information were recorded, and caregivers completed an oral health knowledge (OHK) questionnaire. Patients returned for a post-surgery and recall visit. Caregivers received oral hygiene instructions in a motivational-interviewing style.

Results:At the consultation visit all patients were high risk. At the post-surgery visit, only 47% remained high risk …

Characterization Of Leukocyte-Platelet Rich Fibrin, A Novel Biomaterial, Fadi K. Hasan

Theses and Dissertations

Autologous platelet concentrates represent promising innovative tools in the field of regenerative medicine and are successfully used in oral surgery. Several commercial systems exist that generate various forms of platelet concentrates including Platelet-rich plasma (PRP) and Platelet-rich fibrin (PRF). The alpha- granules of entrapped platelets release a variety of peptide growth factors that promotes healing. Usually PRP is a suspension that can be injected into the site of injury or used as a gel with the addition of thrombin (PRP-gel). In contrast Choukroun’s L-PRF is a dense fibrin based biomaterial enriched with platelets and growth factors. The physical state of …

School of Dentistry Faculty Research and Publications

Temporomandibular joint (TMJ) internal derangement (ID) is one of the most common form of temporomandibular disorders. There is evidence showing the increased expression of matrix metalloproteinases (MMPs) in the cells from degenerated TMJ disc. ADAMTS are a large family of metalloproteases which are responsible for proteoglycans degradation. The present study aimed to evaluate ADAMTS-4 and ADAMTS-5 immunohistochemical expression in human TMJ discs from patients affected by ID, and to find out if there is any correlation with the degree of histopathological changes. Eighteen temporomandibular displaced disc specimens and sixteen TMJ disc control were used for the present study. Specimens were …

Investigation Of Force Decay In Aesthetic, Fibre-Reinforced Composite Orthodontic Archwires, Jacob E. Spendlove, David W. Berzins, Jessica E. Pruszynski, Richard W. Ballard

School of Dentistry Faculty Research and Publications

Background/Objectives: Because polymer-based materials typically exhibit viscoelastic properties, the objective was to determine if commercially available, aesthetic, fibre-reinforced composite archwires maintain continuous forces without undergoing force decay when deflected continuously.

Materials/Methods: Quasi force decay was evaluated by comparing three-point bending profiles of nickel–titanium (NiTi) and fibre-reinforced composite archwires (BioMers) prior to and after 30 days of continuous deflection of either 1 or 2mm. Paired t-tests or non-parametric signed rank tests were used to statistically compare pre- and post-deflection bending forces. A control group consisting of wires not subject to the 30-day constant deflection was tested to check whether the initial …

School of Dentistry Faculty Research and Publications

The purpose of this study was to use data from the National Longitudinal Transition Study–2 (NLTS2) to (a) conceptually identify and empirically establish student, family, and school constructs; (b) explore the degree to which the constructs can be measured equivalently across disability groups; and (c) examine latent differences (means, variances, and correlations) in the constructs across disability groups. Conceptual analysis of NLTS2 individual survey items yielded 21 student, family, and school constructs, and 16 were empirically supported. Partial strong metric invariance was established across disability groups, and in the latent space, a complex pattern of mean and variance differences across …

Erupted Complex Odontoma Mimicking A Mandibular Second Molar, Luis Eduardo Almeida, M. O. Andrade, M. A. De Oliveira Filho, Paula C. Trevilatto, Andrea Doetzer

School of Dentistry Faculty Research and Publications

Complex odontoma (CO) is considered one of the most common odontogenic lesions, composed by a miscellaneous of dental tissue such as enamel, dentin, pulp and sometimes cementum. They may interfere with the eruption of an associated tooth, being more prevalent in the posterior mandible. CO has been rarely reported as erupted, being considered an intraosseous lesion. This is a case report of a 17-year-old male with a benign fibro-osseous lesion consistent with CO that was located at the left second molar region, above the crown of the impacted mandibular second molar tooth. The lesion was surgically removed, and the tooth …

Effect Of Additives On Mineral Trioxide Aggregate Setting Reaction Product Formation, Angela M. Zapf, Sharath C.V. Chedella, David W. Berzins

School of Dentistry Faculty Research and Publications

Introduction

Mineral trioxide aggregate (MTA) sets via hydration of calcium silicates to yield calcium silicate hydrates and calcium hydroxide (Ca[OH]₂). However, a drawback of MTA is its long setting time. Therefore, many additives have been suggested to reduce the setting time. The effect those additives have on setting reaction product formation has been ignored. The objective was to examine the effect additives have on MTA's setting time and setting reaction using differential scanning calorimetry (DSC).

Methods

MTA powder was prepared with distilled water (control), phosphate buffered saline, 5% calcium chloride (CaCl₂), 3% sodium hypochlorite (NaOCl), or …

An Assessment Of What Factors Affect The Average Number Of Caries Seen Per Visit Among Children Visiting A Mobile Dental Unit In South Central Kentucky, Breion Douglas

Mahurin Honors College Capstone Experience/Thesis Projects

Background: Dental caries is the single most common chronic childhood disease in Kentucky affecting 20% of preschoolers, 50% of second graders, and 75% of 15 year olds. Dental caries, also known as tooth decay, occurs when bacteria from salivary glands produce an acid to breakdown food. If this acid is not cleaned off the teeth, it can destroy the tooth enamel. Dental problems can be linked to the inability to pay for dental care (i.e. insurance), limited access to dental providers, and parental inability to take their children to dentists. To help address the issue with tooth decay seen among …

On The Symbolism Of The White Coat, David A. Nash

Oral Health Science Faculty Publications

The white coat ceremony has become an academic ritual in the health professions: a ceremony that signals a transformation of status from ordinary student to that of one studying to become a health professional. While donning the white coat is a sign of a changed role, the white coat is also a powerful symbol of transformation. White is a symbol of purity, and the white coat symbolizes the purity of purpose being affirmed in becoming a health professional. Dentistry is afforded the status of a learned profession as a result of the power dentists possess over patients seeking care; this …

The Effect Of Root Canal Cleansing On The Retention Of Glass Fiber-Reinforced Posts, Faisal Dhaifallah Al-Qarni

Loma Linda University Electronic Theses, Dissertations & Projects

Esthetic glass fiber-reinforced posts are being used more often. The most commonly reported complication associated with these posts is debonding. Dentine conditioning with solutions such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal dentin. Therefore, the purpose of this study was to investigate the effect of cleansing the post space with MTAD or EDTA on the bond strength of glass fiber-reinforced posts, when cemented with self-adhesive resin cement. Forty-five (n=15) extracted human premolar teeth were sectioned at the cemento-enamel junction to obtain root length of fifteen millimeters. Endodontic …

The Role Of Porphyromonas Gingivalis In The Regulation Of Epithelial-Mesenchymal Transition Markers In Migration., Akintunde Ojo 1981-

Electronic Theses and Dissertations

A relationship between periodontal disease and oral squamous cell carcinoma (OSCC) has been demonstrated in recent studies. Porphyromonas gingivalis’ antigen have been found in oral cancer cells. The embryonic program “epithelial-mesenchymal transition” (EMT) is thought to trigger cancer invasion by allowing tumor cell propagation. The objective of this study was to examine the role of P. gingivalis in the expression of ZEB1, vimentin, and repression of miRNA-200 family as EMT prognostic markers in cancer cell metastasis. Human telomerase immortalized gingival keratinocytes (TIGK) cells were challenged with P. gingivalis strain ATCC 33277 in vitro for 24h at MOI 50 and 100. …
