Availability Of Dental Anomaly Phenotype In Individuals With Familial Adenomatous Polyposis, Andrea M. Lewis

Dissertations & Theses (Open Access)

Background: Mutations in the APC gene cause familial adenomatous polyposis (FAP), an autosomal dominant colorectal cancer predisposition associated with the development of hundreds to thousands of adenomatous colorectal polyps beginning in childhood or adolescence. Both malignant and non-malignant extracolonic manifestations are associated with APC gene mutations, including approximately 17% of individuals with various dental anomalies. The availability of dental anomaly information in the medical record remains to be evaluated.

Methods: Medical records were reviewed for documentation of dental anomalies. Dental questionnaires were mailed to 271 individuals with FAP at The University of Texas M. D. Anderson Cancer Center (UTMDACC) to …

Accelerated Aging Effects On Color And Translucency Of Flowable Composites, Yonca Korkmaz Ceyhan, Joe C Ontiveros, John M Powers, Rade D Paravina

Journal Articles

OBJECTIVES: To evaluate the effect of accelerated aging on color and translucency parameter of composites.

MATERIALS AND METHODS: Filtek Supreme Ultra Flowable, shades A1, A3, White, Tetric EvoFlow, shades A1, A3, Bleach, and Filtek Z250 shades A1, A3, B1 were evaluated. Color and translucency were recorded using a spectrophotometer after 24-hour storage (baseline) and after accelerated aging. The data were analyzed by analysis of variance.

RESULTS: Fisher's PLSD intervals for comparisons among products and shades were 0.4, 0.1, 0.3, and 0.4 for ΔL*, Δa*, Δb*, and ΔE*, respectively. The data showed significant ΔE* and ΔL* main effects for composite product …
