Measurement of arch widths in a human population: relation of anticipated bite marks.

The authors compared arch width measurements of diagnostic dental models obtained from dental school patients. Arch width measurements were taken in the canine area on each dental cast in an effort to assist forensic dental investigators in matching certain classes of subjects to the bites they might possibly inflict. If any canine teeth were absent, the measurements were taken using other specified adjacent teeth which the investigators felt would be interpreted as the arch width determiners in a bite mark injury. The ages of the subjects varied from 14 to 87 years. Statistical comparison of the maxillary arch width, mandibular arch width, and the mean difference between maxillary and mandibular arch width were performed. Significant differences between the arch width measurements were found to exist between several classes of subjects based on race and sex.

Assessment of dental students' attitudes toward cancer using a paired comparison technique.

The purpose of this paper is to present a description of the development of an instrument to measure attitudes towards cancer. The instrument used a paired comparison technique to assess dental students' attitude toward patients with cancer in relation to other diseases of patients they would encounter in practice. Nine diseases including cancer were paired in 36 combinations. A shift in the ranking of cancer when compared with other serious diseases would indicate a change in attitude. The attitude instrument was administered to 67 students at the beginning and end of a junior oncology course. Analysis of the paired comparison resulted in rankings for the diseases from least to most preferred. The ranking for cancer moved from second to fourth indicating a positive attitude change. The importance of the students' attitude toward encountering patients with cancer and implications for this technique in attitude measurement are discussed.

Information needs of practicing dentists.

Dentists, as health professionals, need access to information. As in other health sciences, the increase in the rate and volume of published information has made it more difficult for them to keep up with new developments. Five hundred randomly selected dentists in Louisiana were surveyed to determine what information dentists seek and what sources they prefer. Responses indicated that dentists need information on new techniques in dentistry and that preferred sources are professional colleagues and personal journal collections. Libraries were found to be used only infrequently as sources for information. Implications for planning libraries for applications- and technique-oriented professions are discussed.

Questionnaires addressing the attitudes of football officials toward National Collegiate Athletic Association (NCAA) mouthguard rules were developed and distributed to officials in the Big East Football Conference, the Southeastern Conference, and to head football coaches at Division 1-A colleges. Response rates, which ranged from 92.45% to 100%, showed that all groups agreed that football officials are less accountable for player compliance than are coaches, trainers and players. However, officials not only observed a lower rate of compliance with NCAA mouthguard regulations than coaches, they also expressed reluctance to enforce NCAA-sanctioned penalties for failure to comply with mouthguard regulations.

Comparative evaluation of college football officials' attitudes toward NCAA mouthguard regulations and player compliance.

A 12-item questionnaire addressing attitudes of football officials toward the 1990 National Collegiate Athletic Association (NCAA) mouthguard regulation was sent to all officials in the Southeastern Conference (N = 62). The response rate was 95% (59). Twenty-seven per cent of officials reported that all players were in compliance; 74% believed the new rule to be at least somewhat beneficial in determining player compliance, and 20% reported that the rule had resulted in more frequent player use. Twenty-two per cent reported they would ignore a mouthguard violation and none had charged a time-out or called a penalty during the 1991 season. Significant differences in the responses of Big East officials surveyed in a previous study were noted by the authors, when compared to the SEC, but both groups of officials strongly supported the idea that wearing mouthguards should be the responsibility of coaches rather than officials.
