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 …

Restorative Characteristics Of Intrapulpally Cracked Teeth, Charles M. Beavers
Restorative Characteristics Of Intrapulpally Cracked Teeth, Charles M. Beavers
Theses and Dissertations
Cracked teeth have long presented a diagnostic challenge. Previous investigators have considered possible predictive factors, many of which revolve around the tooth’s restorative characteristics. Few have investigated the restorative status of teeth with cracks extending into the pulp chamber. The purpose of this investigation was to determine the prevalence of the different types of restorations present in intrapulpally cracked teeth and determine any other restorative factors that may aid in predicting the presence or extent of an intrapulpal crack. Intrapulpally cracked molars requiring endodontic therapy at the VCU Graduate Endodontic Practice were included in this study. For each tooth, the …

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.

Purpose: The purpose of this retrospective chart review was to determine how primary molars needing vital pulp therapy have been treated in the past four years at Virginia Commonwealth University (VCU) and to determine which treatments: indirect pulp therapy (IPT), formocresol pulpotomy, and ferric sulfate pulpotomy have been successful. Methods: AxiUm records that contained the procedure codes D3120 (Pulp Cap – Indirect) or D3220 (Therapeutic Pulpotomy) were totaled by year. Visit records were queried again to identify treatment failures i.e. extractions or pulpectomy. Results: In 2010, 52% of vital pulp therapies were ferric sulfate pulpotomies and in …
The Prevalence, Predictive Factors, And Classification Of Intrapulpal Cracks In Maxillary Premolars Requiring Endodontic Treatment, Sarah Krygowski
The Prevalence, Predictive Factors, And Classification Of Intrapulpal Cracks In Maxillary Premolars Requiring Endodontic Treatment, Sarah Krygowski
Theses and Dissertations
Cracked teeth may be difficult to diagnose. Craze lines rarely become symptomatic or require treatment. Cracks in the enamel and dentin alone may or may not become symptomatic and require restorative treatment. However, cracks extending into the enamel, dentin, and pulp chamber provide an avenue for bacteria to establish infection and this commonly results in symptoms and the need for endodontic and restorative treatment. The published endodontic literature has limited information regarding the prevalence or predictive factors for cracks extending into the pulp chamber of teeth. The purpose of this study was to determine the prevalence and classification of intrapulpal …

Treatment Decisions Involving Teeth With Intrapulpal Cracks: A Survey Of Endodontists, Sheldon M. Sealey
Theses and Dissertations
There is no universal protocol for diagnosing, treating and managing cracked teeth. The purpose of this survey was to investigate the use of traditional methods of crack detection and to explore how treatment decisions were made using an intrapulpal crack classification. The electronic survey was sent to 1115 active members of the American Association of Endodontists (AAE) and The Digital Office (TDO™) community. Comparisons were assessed using logistic or repeated-measures regression. The most often used diagnostic method was probing. When the crack involved one wall, 85% of respondents would complete root canal therapy > 50% of the time or …
In-Vitro Assessment Of A Novel Bracket's Effect On Resistance To Sliding, James Blackburn
In-Vitro Assessment Of A Novel Bracket's Effect On Resistance To Sliding, James Blackburn
Theses and Dissertations
Friction, binding and notching are the factors that contribute to resistance to sliding during orthodontic tooth movement. However, most attempts at reducing resistance aim only to reduce the archwire/ligature friction. In this study, a novel bracket with a unique design aimed to reduce all three components of resistance to sliding. Four types of brackets (passive and active self-ligating, traditionally ligated and the novel bracket, (n=5, each) were tested at 0, 2, 4, 6, and 8ᵒ of tip on a 0.019 x 0.025”archwire. The resistance to sliding values were recorded. At 0ᵒ, the passive self-ligating and novel bracket showed reduced resistance …

Peracetic Acid: A Practical Agent For Sterilizing Heat-Labile Polymeric Tissue-Engineering Scaffolds, William R. Trahan
Theses and Dissertations
Advanced biomaterials and sophisticated processing technologies aim to fabricate tissue-engineering scaffolds that can predictably interact within a biological environment at a cellular level. Sterilization of such scaffolds is at the core of patient safety and is an important regulatory issue that needs to be addressed prior to clinical translation. In addition, it is crucial that meticulously engineered micro- and nano- structures are preserved after sterilization. Conventional sterilization methods involving heat, steam and radiation are not compatible with engineered polymeric systems because of scaffold degradation and loss of architecture. Using electrospun scaffolds made from polycaprolactone (PCL), a low melting polymer, and …

Functional Characterization Of Rai1 In Zebrafish, Joshua S. Beach
Theses and Dissertations
Smith-Magenis Syndrome (SMS; OMIM #182290) is a multiple congenital abnormality and intellectual disability (ID) disorder caused by either an interstitial deletion of the 17p11.2 region containing the retinoic acid induced-1 (RAI1) gene or a mutation of the RAI1 gene. Individuals diagnosed with SMS typically present characteristics such as ID, self-injurious behavior, sleep disturbance, ocular and otolaryngological abnormalities, craniofacial and skeletal abnormalities, neurological and behavioral abnormalities, as well as other systemic defects and manifestations. Previous work by Vyas in 2009 showed temporal expression of rai1 in zebrafish embryos as early as 9 hpf. We hypothesize that there is maternal …

Lowering The Number Of False Positive Responses To Electric Pulp Tests By Qualifying Patient Response, Katherine Js Lee
Lowering The Number Of False Positive Responses To Electric Pulp Tests By Qualifying Patient Response, Katherine Js Lee
Theses and Dissertations
The electric pulp test (EPT) has been shown to be a valuable tool in assessing pulp vitality. One of its drawbacks, however, is its high number of false positives. The purpose of this study was to determine if qualifying the type of sensation elicited by the test could lower the percentage of false positive responses. A retrospective chart review of an eleven-month period was conducted, examining all patients with necrotic teeth tested with the EPT. Of 189 teeth, when the patient responded to EPT at first sensation 23.3% of teeth were incorrectly identified as vital. When the patient was asked …
