A Scanning Electron Microscopy Comparison Of The Effects Of The Arkansas Stone And The Ida-Hone Ceramic Stone On Curet Sharpness And Root Smoothness, Marian Gayle Rubino

Dental Hygiene Theses & Dissertations

Purpose: The purpose of this study was to determine if there are statistically significant differences between the Arkansas sharpening stone and the Ida-Hone ceramic sharpening stone in producing a sharper cutting edge on dental curets, and to determine if there is a statistically significant difference between the degree of root smoothness achieved by the sharpened curet cutting edges on extracted human teeth.

Methods: A two-group, randomized subject (n=39), double blind, post-test only design was employed using 39 factory new Hu-Friedy 11/12 gracey curets. Curets in group one were sharpened using the Ida-Hone ceramic stone, curets in group two were sharpened …

Sulphur By-Product: A Potential Indicator Of Early Dental Plaque-Induced Gingival Disease Activity: A Pilot Study, Hui Zhou

Dental Hygiene Theses & Dissertations

The purpose of this study was to determine the relationship between volatile sulfide compounds and gingival health status, and to identify if volatile sulfide compounds can detect early dental plaque-induced gingival disease, using an experimental gingivitis model. The sample consisted of 12 subjects between 19 and 28 years, with a healthy gingival status. A split-mouth design utilizing only the mandibular arch was used. A baseline full-mouth periodontal probing status was measured. After baseline data collection and for two weeks, subjects refrained from brushing and flossing one randomly selected half of the mandibular arch. At baseline and six subsequent appointments, gingival …
