Loss of periodontal attachment in adolescents.

Loss of attachment as measured by a portion of Ramfjord's Index (PDI) was determined in 383, 12-16-year-old schoolchildren in rural Juniata County, PA. Prevalence and distributions were tabulated for sex, last dental visit, and type of treatment received. Dental knowledge test scores, toothbrushing effectiveness periodontal status and oral cleanliness were determined at annual intervals from Spring '75 to Spring'79. Mean scores were contrasted with bone loss measurements. 47.3% had loss of attachment (greater than 1 mm) including 24.5% with 2mm or more of attachment loss per mouth. Females (41.0%) ahd significantly lower prevalence rates than males (52.7%). Students who visited a dentist in the last 6 months and who received scaling had less bone loss, lower GI, PII, PI, and QHI scores. An inverse relationship was found between dental knowledge and the other variables measured. Similar patterns were seen with high, medium and low bone loss groups. Many variables in this study were associated with bone loss, including: plaque, dental knowledge, dental behavior (toothbrushing and visiting a dental clinic), recent treatment received and sex. None appeared more significant than the others.

Identification of typologies derived from child behaviors in the hospital as predictors of psychological upset.

This study proposed to measure objectively the behaviors of children in the hospital setting in order to combine the data on the particular aspects of behaviors or symptoms into global measures or typologies of psychological upset. It attempts to offer a good, single measure for predicting behavior of children in psychological upset. Thirty-one subjects in this study, observed in the hospital setting, are clustered together to identify typologies derived from child behaviors in the hospital. These children were divided into three factors which correspond with the three stages of hospitalization: Factor I typified Stage III -- Denial; Factor II typified Stage II -- Despair; and Factor III typified Stage I -- Protest. The study offers direction to objectively and systematically evaluate the effects of hospitalization on children. It also suggests that observational ratings of child behaviors in the hospital may be accurate predictors of the degree of psychological upset a child is experiencing at a certain point in time. It also has particular implications for strategies which hospital staff could employ when they observe particular stages that children manifest.

Dental health knowledge tests: their development, implementation and evaluation.

The present study discusses the development of dental health knowledge tests as part of an integrated dental health curriculum in the public school system of a rural community. It is part of a large project designed to test the effectiveness of a school-based dental health delivery system. Cognitive measures of dental health were designed to study the relationship of dental health knowledge to oral health behaviors. A review of the literature revealed no suitable dental health knowledge tests for grades K-6; new assessment measures were then developed by project staff. The tests consisted of 14 objectively scored tests--two parallel forms at each of the seven grade levels, K-6, and were administered four times to 1,942 students. Consistently, the tests have demonstrated high reliability estimates and low standard errors of measurement and indicate that the instruments are functioning as parallel forms and measuring the same dental concepts with equal precision.
