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 …
A Justification For The Trend Towards Indirect Pulp Therapy, Marissa Kuhnen
A Justification For The Trend Towards Indirect Pulp Therapy, Marissa Kuhnen
Theses and Dissertations
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 …
Treatment Decisions Involving Teeth With Intrapulpal Cracks: A Survey Of Endodontists, Sheldon M. Sealey
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 …
Esthetic Posterior Stainless Steel Crowns And Their Relative Shear Strengths, Lonny Dale Carmichael
Esthetic Posterior Stainless Steel Crowns And Their Relative Shear Strengths, Lonny Dale Carmichael
Theses and Dissertations
Purpose: The purpose of this study was to evaluate esthetic posterior stainless steel crowns (EP-SSC) and compare their relative shear strengths.Methods: Sixty EP-SSC were compared. 15 crowns from NuSmile® Primary Crowns, Kinder Krowns, and Dental Innovators 1UP and EC Crowns were studied. The crowns were cemented to a typodont tooth then thermally cycled in water baths to simulate oral conditions. Shear strengths were evaluated by subjecting these crowns to simulated forces of occlusion.Results: The force required to cause shearing of the esthetic facings was statistically significant. With the 1UP crown being significantly weaker than the other crowns tested. Conclusion: The …
Concurrent Whitening And Orthodontic Treatment, Jason Thomas Gladwell
Concurrent Whitening And Orthodontic Treatment, Jason Thomas Gladwell
Theses and Dissertations
The aim was to evaluate whether a whitening system, when used during the final stages of orthodontics, would yield results comparable to whitening alone. Patients were assigned to either the control (n=20) or experimental (n=26) groups. At T1, patients were given a ten day supply of Trèswhite⢠by Opalescence®, instructions on use, and initial shade determination was made and photographs were taken. At T2 and T3, shade determination was accomplished and updated photographs were taken. Whitening of the teeth occurred in both groups on average, but significantly more whitening was experienced in the experimental group (p < 0.004). An average of 87% of teeth whitened during orthodontic treatment compared to 97% of control teeth (p < 0.01) were judged to be uniform in appearance. In conclusion, the data do not contraindicate the concurrent accomplishment of teeth whitening during orthodontic treatment.
