Polypharmacy is a common cause of salivary hypofunction, producing symptoms of dry mouth or xerostomia, especially among older populations. As the number of older people continues to increase, polypharmacy-induced salivary hypofunction is becoming an increasing problem. Many over-the-counter products are available for relieving symptoms of dry mouth, but few have been tested in controlled clinical investigations. The purpose of this investigation was to evaluate the safety and efficacy of a group of topical dry mouth products (toothpaste, mouth rinse, mouth spray and gel) containing olive oil, betaine and xylitol. Forty adults were entered into this single-blinded, open-label, cross-over clinical study and 39 completed all the visits. Subjects were randomly assigned at baseline to using the novel topical dry mouth products daily for 1 week, or to maintain their normal dry mouth routine care. After 1 week, they were crossed over to the other dry mouth regimen. The results demonstrated that the use of the novel topical dry mouth products increased significantly unstimulated whole salivary flow rates, reduced complaints of xerostomia and improved xerostomia-associated quality of life. No clinically significant adverse events were observed. These data suggest that the daily use of topical dry mouth products containing olive oil, betaine and xylitol is safe and effective in relieving symptoms of dry mouth in a population with polypharmacy-induced xerostomia.

OBJECTIVE: To determine if 2 commercial mouthrinses, 1 alcohol-based and 1 nonalcohol-based, affect salivary flow and symptoms of dry mouth in nonxerostomic adults. METHOD AND MATERIALS: This observer-blinded, randomized, crossover pilot study involved 20 adults. The primary endpoints of interest were whole salivary flow rates and the perceived mouth dryness VAS scores following 1 week of use. ANOVA was used to determine differences in these endpoints between groups, and ANCOVA was used to control for any variation in baseline flow rates and VAS scores (P <.05). RESULTS: There were no significant differences between groups at baseline. After 1 week of mouthrinse use, ANOVA and ANCOVA of combined data (before and after crossover) revealed no significant differences in either flow rates or VAS scores between groups (P >.05). CONCLUSION: There were no differences in objective or subjective measures of mouth dryness between alcohol- and nonalcohol-containing mouthrinses after 1 week in nonxerostomic subjects

The main aims of this cross-sectional study were: (i) to assess the frequency of genital (vulval) lichen planus (VLP) and vulval lichen sclerosus (VLS) in women affected with oral lichen planus (OLP), regardless of the genital symptoms reported; and (ii) to verify whether any demographic, clinical, or histological features of OLP are associated with a higher risk of vulvo-vaginal involvement. Fifty-five women, presenting OLP, consecutively underwent gynaecological examination and, if they demonstrated positive clinical signs of VLP, underwent biopsy. After a drop-out of 14 subjects, 31/41 (75.6%) were found to have signs of genital involvement, of which 13/31 (44.0%) were asymptomatic. Following genital biopsy, 27/31 (87.1%) had histologically confirmed VLP or VLS. Following both univariate and multivariate statistical analyses, no significant association was found between gynaecological concomitance and demographic, clinical, histological features of OLP. This unpredictably common genital involvement in females with OLP emphasizes the importance of routinely performing both oral and gynaecological examinations, to facilitate an early and correct therapeutic approach.

Smokeless tobacco and areca nut are popular with South Asians and South Asian immigrants, most commonly used as paan and gutka. Their regular use leads to oral cancer. The South Asian community in the U.S. is rapidly growing, where paan and gutka are readily available. The study was the first exploration of the migration of the paan and gutka habits, and their use in the U.S.A 108-item questionnaire on paan and gutka usage and beliefs was administered to 138 first-generation Bangladeshi and Indian-Gujarati immigrant adults at community sites in the New York metropolitan area. Forty-five percent Indian-Gujaratis reported ever-regular paan use; of which 5% are current users. Thirty-one percent reported ever-regular gutka use; of which 77% are current users. Thirty-five percent Bangladeshis reported ever-regular paan use; of which 70% arc current users. Nine percent reported ever-regular gutka use; of which 67% are current users. Bangladeshis are more likely to identify paan as causing oral cancer. Indian-Gujaratis are more likely to identify gutka as causing oral cancer.Between the two communities, there were significant differences in paan and gutfca usage, migration effects, and oral career risk perception. There is a need for comprehensive migration studies on the determinants of usage, and for community-specific interventions for these carcinogenic products.

OBJECTIVE: The purpose of this study was to describe the utility of oral chemiluminescent lighting (FDA-cleared ViziLite) as an adjunct to standard visual examination (SVE) to enhance visualization of mucosal lesions, particularly those "clinically suspicious" for oral pre-cancer or cancer. Subjects were considered at risk for oral cancer or pre-cancer if they have no a priori knowledge of the presence or absence of an oral lesion at the time of examination. METHODOLOGY: Five-hundred and one consecutive consenting subjects, over 40 years of age and with a positive tobacco history, received a standard visual examination with conventional incandescent lighting, followed by chemiluminescent lighting. All lesions were recorded, and for lesions detected by both screening modalities, comparisons were made of the subjective parameters of lesion brightness, sharpness, surface texture, and relative size. RESULTS: A total of 410 epithelial lesions were detected in 270 subjects by standard visual examination, of which 127 were clinically "suspicious" for oral cancer and pre-cancer. Ninety-eight lesions were also visualized by chemiluminescent lighting as "aceto-white" (CL+), in addition to six lesions not previously seen by standard visual examination. Seventy-seven of the CL+ lesions (78.5%) were clinically suspicious; all "suspicious" lesions with an ulcerative component and ulcerated lesions consistent with trauma were CL+. Leukoplakias were significantly more likely to be CL+ than erythroplakias (p < 0.01). Overall, those lesions illuminated by chemiluminescent lighting appeared brighter, sharper, and smaller compared to incandescent illumination. CONCLUSION: The results of this study suggest that oral chemiluminescent lighting, when used as a screening adjunct following the standard visual oral examination, provides additional visual information. Leukoplakias may be more readily visualized by chemiluminescence. Studies are underway to explore the clinical significance and predictive value of oral chemiluminescent lighting.

BACKGROUND: The authors present statistics and long-term trends in oral and pharyngeal cancer (OPC) incidence, mortality and survival among U.S. blacks and whites. METHODS: The authors obtained incidence, mortality and five-year relative survival rates via the Surveillance, Epidemiology and End Results (SEER) Program Web site. Current rates and time trends for 1975 through 2002 are presented. RESULTS: From 1975 through 2002, age-adjusted incidence rates (AAIRs) and mortality rates (AAMRs) were higher among males than among females and highest for black males. By the mid-1980s, incidence and mortality rates were declining for black and white males and females; however, disparities persisted. During the period 1998-2002, AAIRs were more than 20 percent higher for black males compared with white males, while the difference in rates for black and white females was small. AAMRs were 82 percent higher for black males compared with white males, but rates were similar for black and white females. Five-year relative survival rates for patients diagnosed during the period 1995-2001 were higher for whites than for blacks and lowest for black males. CONCLUSIONS: Despite recent declines in OPC incidence and mortality rates, disparities persist. Disparities in survival also exist. Black males bear the brunt of these disparities. PRACTICE IMPLICATIONS: Dentists can aid in reducing OPC incidence and mortality by assisting patients in the prevention and cessation of tobacco use and alcohol abuse. Five-year relative survival may be improved through early detection

Recurrent aphthous stomatitis (RAS) and recurrent oral herpes-including recurrent herpes labialis (RHL) and recurrent intraoral herpes (RIH)--are two of the most common oral ulcerative disorders. Despite their benign nature, both may be associated with pain, discomfort, and social avoidance. This article presents methods for dental professionals to diagnose and manage patients with these conditions
