Two hundred fifty-seven patients with oral leukoplakia were studied and followed for an average period of 7.2 years. All lesions were more than one cm in size and had been present and observed for a minimum of 6 months. Of the initial biopsies, 235 revealed a benign hyperkeratosis and 22 others contained some degree of epithelial dysplasia. Seventy-three(More)
There has been clinical speculation that parents of young stuttering children have expectations of their children's communication abilities that are not well-matched to the children's actual skills. We appraised the language abilities of 15 children close to the onset of stuttering symptoms and 15 age-, sex-, and SES-matched fluent children using an array(More)
OBJECTIVES Proliferative verrucous leukoplakia is a unique form of oral leukoplakia that has a high risk for becoming dysplastic and transforming into squamous cell carcinoma. The purpose of this review is to update patient profiles, pathogenesis, and survival. STUDY DESIGN Fifty-four patients with proliferative verrucous leukoplakia (17 from a previous(More)
The risk for oral mucosal lesions associated with use of smokeless tobacco among 1,109 professional baseball players during spring training in 1988 was investigated. Leukoplakia was very strongly associated with use of smokeless tobacco in this population of healthy young men. Of the 423 current smokeless tobacco users, 196 had leukoplakia compared to seven(More)
The majority of work that suggests a relationship between syntactic complexity and the frequency of stuttering has been carried out with young children. In this paper, we investigate whether or not syntactic complexity exerts an influence on the frequency of stuttering in adolescent speech. Fourteen adolescents, 7 of whom stuttered, and 7 of whom were(More)
Oral cancer currently strikes about 30,000 Americans each year. Survival rates are approximately 50%. However, early detection followed by appropriate treatment can increase cure rates to about 80%, and greatly improves the quality of life by minimizing extensive, debilitating treatments. An early oral cancer can appear as an innocuous red or white change,(More)
In Gujarat, India, 57,518 industrial workers over 35 years old were examined for oral lesions. At a two-year interval, 43,654 workers were re-examined. Biopsies were taken from 13,223 lesions. In the initial examination, 29 oral cancers were diagnosed, representing a prevalence rate of 50/100,000. After two years, 22 new oral cancers were diagnosed,(More)
Conventional visual examination and palpation remains the gold-standard for the identification of oral mucosal lesions. The purpose of this study was to investigate the adjunctive value of a chemiluminescent light source (ViziLite, Zila Pharmaceuticals, Phoenix, Arizona) and application of pharmaceutical grade toluidine blue (TBlue(630), Zila(More)
