Children's dietary recalls: the salience of entree and liking for foods on accuracy and order of reporting.
This study investigated the impact of entree and liking for foods on the accuracy and order of reporting on children's school lunch recalls. Data were collected during a series of studies to investigate children's lunch recalls from a cognitive processing approach to understand better how children remember what they have eaten. Fourth-grade children from four schools were randomly selected, observed eating lunch, and interviewed the same (n = 89) or next (n = 148) day. Foods were classified as matches (observed and reported eaten), omissions (observed but not reported eaten), or phantoms (not observed but reported eaten), and corresponding rates were calculated. Statistical analyses included z tests and permutation tests. For same- and next-day recalls, children were more likely to report entree than other meal components earlier in the interview. For next-day recalls, the phantom rate for the remaining items was lower for children who reported entrees accurately versus inaccurately. For items liked "a lot" compared with items "not liked a lot," match rates were higher for next-day recalls, and phantom rates were lower for both same- and next-day recalls. Because entree and liking for foods appear to play salient roles in children's dietary recalls, these results provide guidance regarding the development of specific prompts to increase the accuracy of children's dietary recalls.

Gender differences in the characteristics of dental services provided for children.
The purpose of this project was to describe the differences and similarities in the practice of dentistry for children by male and female dentists. A once-mailed survey with a series of questions regarding the characteristics of their dental practices was sent to a random sample of 3,000 dentists. There were 1,154 useable responses (39 percent). Approximately 8 percent of the respondents were women, which is representative of the percentage of female dentists practicing in the United States. Chi square analysis was employed. There were differences in the practice characteristics of the male and female dentists responding to this survey. The female respondents were: significantly younger; had been in practice for a shorter period of time; more likely to be employees rather than solo practitioners; more likely to treat younger patients; less likely to do comprehensive orthodontic treatment and more likely to use physical restraints than their male counterparts.

Dentists' perceptions of selected characteristics of their child patients.
The purpose of this project was to examine the perceptions of both general and pediatric dentists regarding selected characteristics of the children they treat. A survey including questions on patients' ages, caries activity estimates, and types of patients treated was mailed once to a national random sample of 2,000 general and 1,000 pediatric dentists. The respondents provided a reasonable distribution by age and location, with the majority (69%) in practice more than 10 years. The pediatric dentists who responded perceive that they treat a younger population of child patients with more caries activity (P < 0.001), except in those patients older than 12 years. They also perceive that their patients pools include a larger percentage of patients with handicapping conditions (P < 0.01), behavior problems (P < 0.001) and patients who require treatment with general anesthesia (P < 0.001) than do the general dentists.

Dentists' perceptions of the variety of dental services provided for children.
The purpose of this project was to describe the variety of dental services provided to child patients by general dentists and pediatric dentists. A survey was mailed to a random sample of 2000 general dentists and 1000 pediatric dentists requesting information about the dental services provided to children. Six hundred sixty-two general dentists (33 percent) and 492 pediatric dentists (49 percent) responded. Pediatric dentists reported more frequently obtaining informed consent (p < .0001), placing strip crowns (p < .0001), steel crowns (p < .0001) and pulp treatment procedures (p < .0001). Sealant use in both groups was high but the general dentists reported more frequently sealing occlusal surfaces with incipient caries (p < .001). There were differences in the reported provision of orthodontic services. The general dentists were more likely to refer children for treatment while the pediatric dentists reported they performed limited or comprehensive orthodontic treatment (p < .0001). The results of the survey demonstrate that pediatric dentists perceive that they provide a broader scope of restorative and orthodontic services.

A predictive model for the polymerization of photo-activated resin composites.
This study investigated the relative significance of irradiation duration (20, 40, 60, or 80 seconds) and intensity; filler type (Silux Plus, a microfill or P-50, a hybrid); and shade (Universal or Gray) on the polymerization of resin composite within the depth of a simulated photopolymerized restoration. From the data, a mathematical model that predicts the extent of resin polymerization based upon the above stated variables was generated. The monomer conversion of specimens was determined by infrared spectroscopy. The results are of great clinical use and indicate that the most significant factor influencing resin composite polymerization is thickness of overlying resin composite. Both duration of exposure and light intensity demonstrate high and equal impact. Color and filler type have only minimal influence. The predictive model for resin composite polymerization provided a very good fit (r2 = .949).

The use of behavior management techniques by dentists across practitioner type, age, and geographic region.
The purpose of this project was to describe the behavior management procedures employed for child dental patients based on practitioner type (general dentist vs. pediatric dentist), age, and geographic location. A survey of practice characteristics, which included questions relating to child behavior management, was mailed once to a national random sample of 3000 dentists--2000 general dentists and 1000 pediatric dentists. The pediatric dentists who responded employed a broader spectrum of management techniques than did the general dentists. Significant regional and practitioner age differences were reported in the use of behavior management techniques. The use of sedation and general anesthesia was reported more frequently in the western regions. Of the five age groups, the 40- to 49-year-old age group reported using the broadest spectrum of behavior management techniques. The survey revealed practitioner type, age, and regional differences in the child behavior management procedures employed by dentists.

A comparative investigation in dogs: 2-year morphometric results of the dental implant--bone interface.
One hundred twenty titanium and ceramic root-form and titanium blade implants were placed into 30 dog mandibles. Twenty-four implants in six control dogs (in situ for 5 months) did not receive prostheses. Ninety-six implants in 24 dogs supported prostheses for 6, 12, 18, or 24 months. Computerized morphometry data presented the percent of the implant surface apposed directly by bone. A three-way factorial analysis of variance was used to assess significance. Individual implant means ranged from 0% (mobile implant) to 71% bone adaptation. From these data, two-stage titanium root-form implants were shown to be apposed by more bone than the other five systems, and overall, titanium implant systems were apposed by more bone than ceramic systems. Between 41% and 50% of the surface of integrated ceramic implants were apposed by bone, whereas between 50% and 65% of the surfaces of titanium implants were apposed by bone. Also, two-stage surgery for blade implants appears important for implant success. Furthermore, the use of Nomarski differential illumination appears to be useful for examining the quality of interfacial bone to correlate with the amount of bone quantified by morphometric protocols.
