Analysis Of Periapical Biopsies Submitted For Histopathological Evaluation: A Retrospective Study, Abdullah I. Alqaied
Master's Theses
Apical periodontitis is the most common pathological process in the periapical region. Disciplined clinical and radiographic evaluations and appropriate diagnostic tests can detect lesions related to apical periodontitis. Aside from this, lesions mimicking pulp-related pathology but unrelated to pulpal infection and necrosis are occasionally discovered in the periapical region. The objective of this study was two-fold: (1) to determine the prevalence of diverse periapically located pathological entities, and (2) to apply that information to evaluate the rationale for routine submission of surgically obtained tissue for histological examination and diagnosis. Methods: A 5-year retrospective analysis of pathology reports from the UCONN …

Sexual Dimorphism In Periapical Inflammation And Bone Loss From Map Kinase Phosphatase-1 Deficient Mice, Justin Mcabee
MUSC Theses and Dissertations
Introduction: Mitogen Activating Protein (MAPK) kinase phosphatase-1 (MKP-1) has been shown to be a key negative regulator of the MAP kinase pathways of the innate immune system. The impact of MKP-1 in an endodontic model has yet to be studied. Thus, the purpose of this study was to determine the role of MKP-1 in a bacterial-driven model of pathological endodontic bone loss. Methods: Pulps were exposed in both lower 1st molars of 10-week old Dusp-1+1+IMKP-1 +1+ and Dusp-1-1-IMKP-1-1- mice and left open to the oral environment for either 3 or 8 weeks. At sacrifice, mandibles were harvested and scanned by …

The Effect Of Canal Preparation On Fill Length In Straight Root Canals Obturated With Realseal 1 And Thermafil Plus, Thomas John Heeren
MUSC Theses and Dissertations
Introduction: A common adverse effect using thermoplasticized obturators is overextension. A canal preparation allowing for predictable obturation length would be of clinical value. This study compared straight canals instrumented to a size 40 file using a 0.04 standardized taper preparation (STP) and a varied taper preparation (VTP) by evaluating the extension of two thermoplastic obturation systems: RealSeall ™ (RS-l) and Thermafil® Plus (TP). Methods: Eighty extracted mature human premolars with single straight canals were randomly divided into 4 experimental groups (n=20). Groups 1 and 2 were instrumented to size 40/04 at working length (WL) with STP. Groups 3 and 4 …

The hypothesis that a cold plasma jet has the antimicrobial effect against Enterococcus faecalis biofilms was tested in vitro. 27 hydroxyapatite discs were incubated with E. faecalis for six days to form a monoculture biofilm on the disc surface. The prepared substrata were divided into three groups: the negative control, the positive control (5.25% NaOCl solution), and the plasma treatment group. Resultant colony-forming unit counts were associated with observations of bacterial cell morphology changes using scanning electron microscopy (SEM). Treatment of E. faecalis biofilm with the plasma and 5.25% NaOCl for 5min resulted in 93.1% and 90.0% kill (P < 0.0001), respectively. SEM detected that nearly no intact bacteria were discernible for the plasmaexposed HA disc surfaces. The demonstrated bactericidal effect of the plasma with direct surface contact may be due to the enhanced oxidation by the locally produced reactive plasma species.

In the following respects, tooth enamel is a unique tissue in the mammalian body: (a) it is the most mineralized and hardest tissue in it comprising up to 95 wt% of apatite; (b) its microstructure is dominated by parallel rods composed of bundles of 40 – 60 nm wide apatite crystals with aspect ratios reaching up to 1:10,000 and (c) not only does the protein matrix that gives rise to enamel guides the crystal growth, but it also conducts its own degradation and removal in parallel. Hence, when mimicking the process of amelogenesis in vitro, crystal growth has to …

Comparison Of Non-Surgical And Surgical Endodontic Retreatment: A Systematic Review, Robert Corr
Loma Linda University Electronic Theses, Dissertations & Projects
Primary root canal therapy has been shown to be a predictable procedure with a high degree of success 1-4, however failures can occur after treatment. Treatment options for the preservation of teeth that have had previous endodontic treatment but demonstrate persistent disease include non-surgical (orthograde) or surgical (retrograde) endodontic retreatment, assuming the tooth is restorable, periodontally sound, and the patient desires to retain the tooth. The purpose of this study was to conduct a systematic review of the current available evidence to compare the clinical and radiographic outcomes of nonsurgical with those of surgical endodontic retreatment. Methodology began with …

Endodontic Residents’ Understanding Of Biostatistics: A 2010 Survey Of Endodontic Residents In The United States, Paul Letellier Jr.
Theses and Dissertations
Endodontic residents must keep current with clinical information to practice evidence- based dentistry. To do so, endodontic residents must access research papers and interpret results. This requires a knowledge of biostatistics. However, the biostatistical knowledge of endodontic residents is relatively unknown. The purpose of the study was to assess the biostatistical knowledge of endodontic residents using a survey instrument to prove or reject the hypothesis that there exists a lack of understanding of biostatistic principles among endodontic residents. A survey consisting of 29 questions querying attitudes and biostatistical knowledge was distributed to 230 endodontic residents and returned with a 32% …

Theses and Dissertations
A survey was conducted to assess the current state of predoctoral endodontic education in the United States. Fifty-one schools received surveys and 73% responded. Seventy-six percent were from public schools with most having a graduate endodontic program (84%). Preclinical training most often began in the spring of second year and clinical training started in the fall of third year (each 54%). All programs that responded stated that endodontists routinely instruct students in the clinic. Sodium hypochlorite 2.5% was the irrigation of choice. Calcium hydroxide was the most common intracanal medicament. Cold lateral condensation with gutta-percha was the most frequently indicated …
Prospects And Pits On The Path Of Biomimetics: The Case Of Tooth Enamel,

Prospects And Pits On The Path Of Biomimetics: The Case Of Tooth Enamel, Vuk Uskoković
Pharmacy Faculty Articles and Research
This review presents a discourse on challenges in understanding and imitating the process of amelogenesis in vitro on the molecular scale. In light of the analysis of imitation of the growth of dental enamel, it also impends on the prospects and potential drawbacks of the biomimetic approach in general. As the formation of enamel proceeds with the protein matrix guiding the crystal growth, while at the same time conducting its own degradation and removal, it is argued that three aspects of amelogenesis need to be induced in parallel: a) crystal growth; b) protein assembly; c) proteolytic degradation. A particular emphasis …
