Dental care utilization among dental students.

The purpose of this study was to determine the proportion of needed dental care actually received by dental students during their dental education. This was accomplished by a review of dental records for recent Baylor College of Dentistry graduates. Collected data included restorative, periodontal, endodontic and extraction procedures planned and dental care actually accomplished prior to graduation. Comparisons of these findings were made based on gender, ethnicity and academic standing of the sample subjects. The sample size of 134 included 98 males and 36 females; 111 were Caucasian and 23 Minorities. Fifty-six individuals were in the upper academic third of their class, 37 in the middle third and 41 in the lower third. The treatments required were primarily operative dental restorations (7.28 +/- 7.19 surfaces per student), crowns (0.43 +/- 1.22 units per student) and extractions (0.90 +/- 1.58 per student). Periodontal and endodontic needs were minimal. Students received approximately 60% of the required care during their dental education. Minimal relationships were identified between gender, academic standing and ethnicity and the students' care needs and treatments. The results suggest a relatively low priority for receiving needed dental care among dental students.

Epidemiologic survey of accidental dentofacial injuries among U.S. Army personnel.

This epidemiologic study of accidental dentofacial injuries to U.S. Army personnel was conducted to determine the frequency and distribution patterns of accidental dentofacial injuries to soldiers. Administratively, it was anticipated that this data would permit identification of high-risk groups and would suggest feasible preventive measures. This 9-month study was conducted on 16 Army posts with a combined population at risk of 210,500 soldiers; a standardized data collection form was completed by the dental corps officer treating the injury case and then was mailed to a central collection site for analysis. The data from this dentofacial injury study clearly reveal that differential risks exist for various military subpopulations. While the overall U.S. Army accidental dentofacial injury rate was 37.7 cases/10,000/year, this rate varied greatly for specific subgroups with high-risk factors including young males, lower enlisted ranks, recent recruits, and combat training posts. The primary specific causes of these injuries were fistfights (nearly 30%), sports (over 20%), and vehicles (about 15%).

A survey of factors possibly associated with cervical abrasion of tooth surfaces.

The study indicates that cervical abrasion is related in some way to a factor or factors associated with the initial stages of the tooth-brushing procedure. The evidence, furthermore, demonstrates that an excessive use of dentifrice habitually placed, undiluted, on the same area of the mouth, may produce the abrasion. In view of this evidence, it would seem prudent to advise patients to use decreased quantities of dentifrice and to initiate the brushing procedure on the occlusal surfaces of the teeth to effect a dilution of the dentrifrice. The same effect might be accomplished by alternating the initial placement of the brush between the quadrants to more evenly distribute the abrasive effect. The high percentage of these lesions found in this young age group demonstrates a higher prevalence of the lesion in a younger age group than was previously suspected. We can further conclude that cervical abrasion is related to age and gingival recession. Furthermore, the study indicates that patients who exhibit cervical abrasion have less plaque and the lower bleeding scores than those who do not.

Effects of two cetylpyridinium chloride-containing mouthwashes on bacterial plaque.

The purpose of this single blind clinical study was to determine the effects of two commerical mouthwashes (one containing cetylpyridinium chloride and domiphen bromide and the other containing only cetlypridinium chloride) on existing plaque accumulations. A second purpose was to determine if a residual effect could be shown 2 weeks after cessation of using these mouthwashes. A total of 120 adult subjects, who had been divided into three groups, were initially in the study. For a period of 31 days, the subjects in Group A rinsed with a commercial mouthwash containing cetylpyridinium chloride and domiphen bromide; Group B rinsed with a commercial mouthwash containing only ceytlpyridinium chloride; and Group C served as controls and rinsed with colored flavored water. All subjects continued their normal home oral hygiene practices, except that mothwashes other than as assigned were forbidden. The subjects received three identical examinations to determine their plaque scores. The examinations were conducted the day preceding initiation; the day following cessation; and 15 days after cessation of the rinsing procedures. A total of 105 subjects received the first and second examinations, and 93 subjects received all three examinations. Based upon the data obtained, the daily use of each of the cetylpyridinium chloride mouthwashes tested, appears to be partially effective in reducing existing bacterial plaque accumulations. The cetylpyridinium chloride-domophen bromide product was slightly, but not significantly, more effective than the other commercial mouthwash. Neither commerical product demonstrated a significant residual effect 2 weeks after cessation of use.
