An in vitro and in vivo study on the relationship of temperature and sodium hypochlorite
No full textThesis (M.Sc.D.)--Boston University, Henry M. Goldman School of Graduate Dentistry, 1988 (Endodontics)Bibliography: leaves 137-144.Sodium hypochlorite is the most widely used irrigant in endodontics. Its ability to dissolve pulp remnants and debris is just one of its important properties that facilitates cleaning and shaping of root canal systems. This tissue dissolving ability has been found to be affected by an increase in temperature. Studies were conducted to investigate this finding.
An in vitro study was undertaken to compare the solvent ability of NaOCl at concentrations of 5%, 4%, 3%, 2% and 1% on human dural connective tissue when pre-warmed individually at constant temperatures of 60[degrees]C, 50[degrees]C, 40[degrees]C, 37[degrees]C and 23[degrees]C using a water bath. Each specimen 4mm in diameter was placed in a test tube containing 10 ml of the given NaOCI concentration and exposed to a constant temperature starting from 60[degrees]C. The rate it took for each specimen to completely dissolve in the pre-warmed NaOCl solution was monitored.
In vivo studies which made use of thermocouples were undertaken to: (a) determine the temperature of a NaOCl solution when inside the root canal system and the rate it took for the solution to reach this temperature and (b) determine the rate it will take for a pre-warmed 60[degrees]C NaOCl solution to stabilize to the temperature within the root canal environment.
Results of the in vitro study indicate that:
a) Both concentrations and temperatures are inversely related to the solvent time of the NaOCI solution.
b) There is no significant difference in the solvent time of 2% - 5% sodium hyphoclorite concentrations when used at temperatures of 37[degrees]C and above.
c) There is a significant difference in the solvent time of 1% sodium hypochlorite solution when used below 60[degrees]C.
Results of the in vivo studies indicate that:
a) The final temperature of a sodium hypochlorite solution (whether it is prewarmed or used at room temperature) when irrigated into the root canal is approximately equal to the temperature of the tooth.
b) The final temperature of a sodium hypochlorite solution inside the root canal is the result of a very complex thermodynamic system which involves the interaction of many factors namely: the temperature of the solution before it is irrigated into the root canal, the temperature of the tooth, the mass of the tooth and the solution, the size and surface area of the root canal, the length and thickness of the tooth, the ambient temperature of the air, the thermal properties (thermal conductivity, heat capacity, conduction, convection and evaporation) of the tooth and solution, and the position of the thermocouple in the canal.
c) A solution of sodium hypochlorite when prewarmed or used at room temperature rapidly approaches thermal equilibrium with the tooth upon irrigation into the canal.
d) In endodontic therapy, it does not appear useful to use a heated solution of sodium hypochlorite in order to enhance its solvent capacity because the sodium hypochlorite solution rapidly establishes thermal equilibrium with the tooth at 36[degrees]C [plus or minus] .1[degree]C.
e) There is a significant difference between an in vivo and an in vitro study with regards to maintaining a prewarmed NaOCl solution at a constant temperature

Voice and silence: A rhetorical analysis of selected works of fiction by Eudora Welty
No full textIn The Rhetoric of Fiction, Wayne Booth discusses the narrative choices an author can make to relate a story to his or her reader. Through point of view and authorial distance, an author can offer a clear and deep insight into the meaning of any story. Booth questions the belief of many modern authors and critics who believe that “showing” a story by deleting all entrances, or “intrusions,” by the author to be far superior to “telling” at story through direct authorial voice or through some form of narrator/s. He believes that by considering the differences between “showing” and “telling” a story, an author forces the reader to “consider closely what happens when an author engages a reader fully with a work of fiction; [authors thus] lead us to a view of fictional technique which necessarily goes far beyond the reductions that we have sometimes accepted under the concept of ‘point of view’” (Booth 8-9). The use of point of view to control audience sympathy and interpretation of the story and the use of authorial distance to “show” rather than “tell” a story are skillfully employed by Eudora Welty in narrative fiction to present stories which connect to universal truths and emotions in the reader
Image selling: how depictions of power relations, plasticity, and abjection in high-fashion advertisements construct terrifying social narratives
No full textThis paper examines how high-fashion advertisements use visual rhetoric in order to construct social narratives related to power struggles, plasticity, and abjection. In creating these types of images, high-fashion advertisers send explicit messages to their viewers regarding the ways they should engage with the depicted social narratives, ranging from objectification to violence to death. Through a close rhetorical analysis and observational study of high-fashion advertisements, this paper discusses the problematic nature of the marketing techniques and how they skew interpretations of social issues
