Self-perceived oral health among three subgroups of Asian-Americans in New York City: a preliminary study.

OBJECTIVES: The aim of this preliminary study was to compare the perception of oral health among subgroups of Asian-American residents of New York City, USA. METHODS: A close-ended questionnaire was administered to 255 Chinese, 134 Indian and 84 Pakistani adults, aged 18-65 years, during 1994-95. A comprehensive dental and oral examination was also performed. The associations of demographic and oral health variables with perceived oral health were evaluated using multivariate ordinal regression models. RESULTS: When data were analyzed in a multivariate context, only ethnicity and income were significant predictors of perceived oral health, after adjusting for DMFT. The within-group multivariate analysis of the three ethnic subgroups' results were as follows: Among the Chinese there were no significant predictors, only income was strongly suggestive; among the Indians, number of missing teeth and number of years in the USA were significant predictors; and within the Pakistani group, DMFT was the only significant predictor. CONCLUSIONS: Results suggest that there are ethnic differences in the perception of oral health status even after adjusting for clinical variables as well as for demographic variables in this particular group of Asian-American residents of New York City. Predictors associated with the perception of oral health are different for each ethnic group. When designing oral health promotion activities to diverse ethnic groups, the cultural characteristics of each subgroup should be considered.

Dental caries in older adults. Current status and management.

Despite encouraging reports of decreasing caries prevalence in children and young adults, dental decay continues to be the major cause of tooth loss in adults. The risk for both coronal and root surface caries, in their primary and secondary forms, increases with advancing age. With recent trends of increasing retention of the natural dentition over a longer period of time, and increasing utilization of dental care services by older adults, the number of restorative procedures performed by dental practitioners is anticipated to increase. Keeping retained teeth healthy in advancing age is a challenge and depends to a large extent on the dentist's ability to develop and implement a preventive-restorative protocol that fits the functional ability and risk status of the individual patient.

Intra-oral comparison and evaluation of the ability of fluoride dentifrices to promote the remineralization of caries-like lesions in dentin and enamel.

The effect of three types of fluoride dentifrices and one non-fluoride dentifrice were evaluated and compared intra-orally for their ability to promote the remineralization of caries-like lesions in thin sections of human dentin and enamel. The three fluoride dentifrices were silica based. One dentifrice contained 0.76% sodium monofluorophosphate (MFP), another contained 0.247% sodium fluoride (NaF), and the third contained 0.247% NaF plus 1.3% pyrophosphate and 1.5% polyvinylmethyl ether/maleic acid (PVM/MA) copolymer (denoted NaF/PPi). The fourth dentifrice (placebo) was also silica based, but contained no fluoride, and served as a negative control. Two week treatment resulted in the following percent mineral changes for the enamel specimens: +21 +/- 16 for MFP, +10 +/- 30 for NaF, +16 +/- 15 for NaF/PPi, and -30 +/- 30 for the placebo. The respective percent mineral change values for the dentin specimens were +28 +/- 20 for MFP, +22 +/- 19 for NaF, +28 +/- 18 for NaF/PPi, and -34 +O/- 61 for the placebo. A statistical analysis revealed that the three fluoride dentifrices were significantly better (p<0.05) than the placebo at promoting remineralization for both types of specimens. No significant differences were found among the three fluoride dentifrices. The following can be concluded from this study: 1) silica based dentifrices containing MFP and NaF are effective at remineralizing caries-like lesions in both enamel and dentin; 2) there was no statistical difference between NaF and MFP in their ability to promote remineralization; and 3) pyrophosphate does not interfere with the remineralizing effects of NaF.

Mucous membrane pemphigoid: a disease of the elderly.

Mucous membrane pemphigoid (MMP) is a vesiculo-bullous, mucocutaneous disease that generally affects elderly people. The diagnosis of mucous membrane pemphigoid may be overlooked since the disease is often confined to the mouth and desquamative gingivitis may be the only symptom. Gerodontic patients with this condition are often diagnosed as having "desquamative gingivitis" without obtaining the proper therapy to control chronic pain and effect disease remission. The discomfort associated with eating may prevent many elderly patients from obtaining adequate nutrition. Topical and/or systemic corticosteroid therapy are the only available methods of managing this condition. Immunologic studies support the autoimmune nature of MMP and infer that it may be a variant of bullous pemphigoid.
