Quantification Of Dental Fissures Through Occlusal Topography Analysis, Duru Erkan

Biological Sciences Undergraduate Honors Theses

Narrow, deep, and elaborate dental fissures are widely believed to increase the predisposition of enamel to develop carious lesions as these surfaces are thought to be ideal for cariogenic bacteria to adhere to. Therefore, dentists prescribe sealants as a preventative measure for patients with such fissures to avoid tooth decay. Yet to date, there is no objective data supporting the notion that fissure morphology actually affects caries susceptibility, nor is there a quantifiable, clinically practical method to characterize fissure patterns expected to increase risk of caries disease.

In this study, three new methods to quantitatively characterize fissure pattern in mandibular …

The Effectiveness Of Resin-Modified Glass Ionomer Varnish In Preventing White Spot Lesions During Fixed Appliance Orthodontic Therapy: An In Vitro Study, Bradley Herman

Theses & Dissertations

The purpose of this investigation was to evaluate the efficacy of a glass ionomer varnish in preventing demineralization of enamel adjacent to and some distance away from an orthodontic bracket. Forty extracted human molars were divided into four different treatment groups (varnish in distilled water, varnish in acetic acid, enamel in acetic acid, and enamel in distilled water). Two 3 x 3 mm graphite windows were drawn on the tooth, one adjacent to the bracket and one 3 mm away from the first window, indicating the scanning area. Varnish was applied to the teeth in the varnish groups and all …

Chlorine Stain And The Oral Cavity, Alexandra B. Moore

Dental Hygiene ETDs

Swimming is known worldwide as one of the healthiest, low-impact forms of exercise and for the subsequent promotion of a strong body, heart, and mind. However, many swimmers and non-swimmers do not realize that swimming in a pool can have a negative effect on the oral cavity. Several studies have suggested that pool chlorination is responsible for dental erosion, calculus formation, and stain in competitive and recreational swimmers, and this phenomenon is known as ‘swimmer’s mouth.’ A pilot experimental research study was conducted that evaluated the prevalence of chlorine stain in the oral cavity of twenty-one female swimmers from the …

Effects Of Flash-Free Technique On Plaque Retention, White Spot Lesions, And Bracket Failure: A Randomized Clinical Trial, Payam Ishani Afousi

Theses & Dissertations

A side effect of orthodontic treatment is the development of white spot lesions (WSLs). This thesis attempted to evaluate the effects of the use of APC™ Flash-Free (FF) and conventional adhesives in bonding of orthodontic brackets on plaque formation and retention, WSL development, and bracket failure in-vivo. This was accomplished by collecting plaque samples from around orthodontic appliances and analyzing them using ATP-driven bioluminescence; scanning enamel surfaces using the Canary System™ to evaluate WSL development, and counting the number of spontaneous debonding of brackets of the 4 maxillary incisors in the first 6 months of treatment. It was found …

Comparing Velscope Vx And Traditional Oral Exams In Shisha (Hookah) Smokers: A Pilot Study, Amanda E. Kimball

The purpose of this study was to compare oral findings using two exam types, the VELscope Vx® screening device versus a modified oral examination in detecting oral potentially malignant lesions in shisha smokers.

Methods: Thirty-one participants who reported currently smoking shisha and tobacco were recruited. Participants were identified for smoking habits to include two groups, to include those who reported smoking shisha exclusively and those who reported smoking shisha and tobacco. Each group received both exam types; examiners used a standardized protocol. A health history questionnaire was also collected to assess participant's oral cancer risk factors such as age, race, …

Bisphenol A Blood And Saliva Levels Prior To And After Dental Sealant Placement In Adults, Joyce Marie Downs

Dental Hygiene Theses & Dissertations

Placement of pit and fissure dental sealants is an effective therapy for tooth decay prevention and is widely accepted as a standard of care throughout the United States. Pit and fissure dental sealants (sealants) are manufactured using the resin component of composite dental materials, formed by reacting glycidyl methacrylate with bisphenol A. Bisphenol A (BPA) is a hormonally active, synthetic chemical that is part of a broad group of chemicals known as endocrine disrupting compounds, xenoestrogens, which mimic bioactivity of estrogen. This study measured BP A in saliva and blood after the placement of a widely used, pit and fissure …

In Vitro Comparison Of 360° Unirotational Disposable Prophylaxis Angles Versus 90° Reciprocating Disposable Prophylaxis Angles On Spatter During Rubber Cup Polishing, Kelly Marie Schulz

Dental Hygiene Theses & Dissertations

The purpose of this in vitro study was to compare the traditional 360° unirotational disposable prophylaxis angle (DPA) to a 90° reciprocating DPA in terms of spatter production. The 2x3x3 factorial design involved: 2 types of DP As x 3 types of prophylaxis pastes (fine, medium and coarse) x 3 dental handpiece revolutions per minute (rpm) settings (1500, 2000, and 3000). The eStylus'™ operated the DP As under controlled speeds. Using a mounted dental manikin, 90° reciprocating DP As and 360° unirotational DP As were evaluated for spatter production with the use of prophylaxis pastes of various grits in 270 …

Dental Hygiene Theses & Dissertations

The purpose of this study was to determine the extrinsic tooth stain removing effectiveness of a 90° counter-rotating disposable prophylaxis angle (DPA) with rubber cup as compared to the traditional 360° unirotational DPA with rubber cup. Four randomly assigned groups of cleaned, sterilized, extracted human teeth, artificially stained with coffee, tea, tobacco, and red wine were polished on the buccal and lingual surfaces using one of the two rubber cup DP As under study. Each dependent variable (four different stain types) was tested four times with each prophylaxis angle, using each of the four prophylaxis paste conditions, and three different …

Effects Of Ultrasonic Scaling And Hand-Activated Scaling On Tactile Sensitivity In Dental Hygiene Students, Danielle Leigh Ryan

Dental Hygiene Theses & Dissertations

This study was conducted in order to determine if tactile sensitivity varies in dental hygiene students who use the ultrasonic scaler as compared to those who scale with handactivated instruments. A convenience sample of 40 consenting, first year dental hygiene students were randomly assigned to one of two groups. The 40 students had not yet used the ultrasonic scaler nor had any history of injuries or disabilities to the dominant arm, wrist or hand. After establishing a baseline tactile sensitivity score with the Vibratory Sensory Analyzer (VSA), experimental group subjects used the ultrasonic scaler to remove 4cc's of artificial calculus …
