Lipid interactions in breadmaking.

Both the natural lipids of flour and added fats are known to play an important role during the production of bread. In this review, the chemical and physical interactions of fat have been assessed in an attempt to explain these technological functions. Particular emphasis has been placed on the "binding" or complexing of lipid by flour proteins during the development of dough. While publications in this field have frequently been contradictory, evidence now indicates that observed lipid binding may involve lipid mesophase transformation and the nonspecific occlusion of lipid phases within the gluten network. The significance of these suggested events has been compared with current theories of lipid function in the breadmaking process.

A factor analysis of traits as measured by COCSTOC-MOT to identify occlusal trait combinations.

Occlusal conditions which vary significantly from accepted social norms for dental appearance may socially handicap an individual. An instrument is required by which socially unacceptable occlusal conditions can be identified by members of the public who have internalized society's norms for acceptable dental appearance. The factors identified in this paper make it possible to select a reasonable number (100) of models for constructing a measurement instrument which depicts the full range of occlusal patterns found in a natural population for use in assessing the social acceptability of occlusal conditions. This paper presents the methodology and process used to identify individual occlusal traits which tend to occur together in trait combinations or independently and their range from "normal" to extreme. Data on the frequency distribution of the individual COCSTOC measurements found in a natural population was subjected to a factor analysis which identified 18 occlusal patterns (combinations of traits) and five unique or independent traits or anomalies.

Provider expectations and consumer perceptions of the importance and value of dental care.

Seventy-eight inner city mothers of third and fourth grade children in three racial groups--white, black, and American Indian--known to need dental treatment for disease on permanent teeth, were interviewed at home by a trained community resident interviewer. Sixty-two per cent of the mothers were on public assistance. Information relating to the mothers' perceptions of the importance and value of dental care both for herself and for her children were collected. Utilization data were obtained via two dental examinations conducted one year apart. Data were also collected from a sample of provider dentists via mail questionnaire. A yield of 315 usable questionnaires was obtained, a return rate of 53 per cent. Provider-dentists felt that low socioeconomic consumers do not value dental services, as compared to other types of consumer goods and services, and that they do not believe dental care is important. Low income mothers in the same city reported that they did value dental care and believed it important. Expectations of and orientations toward the importance of dental care were found discongruent between the two groups of respondents. These discongruities on the dentist-patient relationship are discussed as a barrier to utilization. Although financial resources were available to many of the study families, only 49 per cent of these children received the needed care. It is suggested that the psychological cost to a patient of seeking care in inhospitable settings may act as a barrier to utilization.

Sealant use by general practitioners: a Minnesota survey.

A 1987 random-sample mail survey on the use of sealants by general dentists in Minnesota (71 percent response, N = 375) found that almost all (95 percent) reported using sealants. Usage was predominantly for the six- to fourteen-year-old patient age-group. Frequency of use per week ranged from 1-25 (mean +/- S.D. = 3.3 +/- 3.6). More frequent use was associated positively with employing more dental hygienists, having more sources of information about sealants, having higher knowledge scores, and having more favorable opinions about sealants. While reported use of sealants is high in this state, the frequency of use and proportion of child patients receiving sealants were both relatively low.
