The total number of mast cells present in popliteal lymph nodes of hereditarily asplenic Dh/+ mice is lower than in their normal +/+ littermates. The lymph nodes are larger in Dh/+ mice than in normal +/+ littermates. It is postulated that the spleen in some way regulates the number of mast cells in the lymphoid cell population.
In this study, 1287 patients completed a questionnaire assessing knowledge of home care procedures, adherence to home care instructions, obstacles presented to the dentist in delivering care, and ability to pay for optimal care. Ninety-seven dentists that provided treatment for these patients completed a parallel questionnaire. Measures of oral health and the quality of restorative care were based on clinical examinations. It was found that though patient values and dental perceptions were associated, dentist perceptions did not closely match patient dental values. Analysis of variance indicated that patient dental values were related positively to both oral health measures and the quality of restorations. Patient-reported compliance with home care recommendations showed the strongest relationship to both oral health and quality of restorations.
This study explores the relationship between time to complete a manual dexterity exercise and quality of restorative dentistry. Ninety-seven general practitioners volunteered to take part in the study. An average of 14 patients per office were recalled and an average of five recent restorations per patient were examined clinically by trained peer reviewers. Subsequently, 74 of the 97 dentists participated in a session in which the O'Connor Tweezer Dexterity test was administered. Pearson correlations between speed on the test of tweezer dexterity and quality measures indicated that, on the average, those practitioners who took longer to complete the tweezer test achieved significantly higher scores on restorative quality.

This study investigates dentists' perceptions of their patients and the relation of these perceptions to measures of actual quality of restorative treatment. The results indicate that 1) though the dentists see their patients as "cooperative," they perceived a substantial number of "problems," i.e., willingness to pay for optimal care or follow professional recommendations; and 2) there are significant associations between dentists' perceptions of patients and measures of the quality of restorative treatments; higher quality scores were associated with perceptions of a more cooperative patient.
This report characterizes differences among early and late volunteers, and non-volunteers for personal characteristics and situational determinants of volunteering in an experimental dental peer review study. Differences were found for volunteers/non-volunteers for some items representing subject interest, expectation of a favorable evaluation, sociability, and achievement motivation.
This paper reports the dental care norms for restorative dentistry collected from examinations of 1,466 patients in 105 dental offices in Washington State during 1976. These results are part of a larger study, "Assessment of Care and Continuing Dental Education," being conducted by the University of Washington with the endorsement and cooperation of the Washington State Dental Association. Treatments in volunteer offices were evaluated either by colleagues (peer review) or by the practitioner himself (self-assessment). Two hundred twenty-four of 1,196 eligible dentists volunteered for the study. Patients from the practitioners' offices were randomly selected from office files by project staff. The study tests the proposition that, using standardized clinical evaluation procedures and comparable samples of treatment, dentists will be more critical of their own work than that of others. Results suggest a generally high level of care provided by volunteer practitioners and that self-assessments were significantly more critical than peer review.

Today's dental practice standards are set by the individual dentist. Quality is assured, in large part, by the accuracy of self-evaluations by dental practitioners. As a result, dental educators have attempted to improve the accuracy of self-reported evaluations by dental students by teaching such skills in the laboratory and clinic. This investigation examines multiple self-evaluations of the quality of restorative practice of 1,196 general practitioners, and investigates the relationship between these ratings and actual quality of treatment by 102 dentists for 2,753 patients.

The relationship between preferred objects associated with stereotypy, stereotypic behavior, and accuracy of responding during a counting task by a child with autism was analyzed. Object preference was determined by presenting the child with different sets of objects and asking him to choose one. His choices were then rank ordered into three groups: low, medium, and high preference objects. Counting performance within each of the three object groups was then analyzed in a multi-element design, alternating preference groups. Teaching with high-preference objects occasioned more stereotypic behavior and less accurate counting than teaching with medium- and low-preference objects. Thus, there exists the possibility that teaching may be less successful with certain teaching materials, especially if those materials evoke high rates of incompatible behaviors.
Fear appeals threatening the individual have been shown to be powerful persuasive devices in the cultures where they have been studied. However, most fear appeal research has been conducted with members of individualist cultures. Individualist cultures place self-needs above group concerns, while collectivist cultures place group needs above self-concerns. Little is known about the effectiveness of fear appeals (or other persuasive strategies) in collectivist cultures. Two studies assessed the effectiveness of AIDS-prevention fear appeals threatening the self versus fear appeals threatening the group (i.e., family) on members of individualist and collectivist cultures. The first study focuses on African American and Mexican immigrant junior high school youth. The second study focuses on U.S. and Taiwanese college undergraduates. The results indicated that fear appeals should address cultural orientation (i.e., individualist versus collectivist orientation) to achieve maximum effectiveness. The results also indicate that one cannot assume cultural orientation based on ethnicity.
