A report of two smokeless tobacco surveys and associated intervention strategies among Utah adolescents.

Smokeless tobacco is an increasingly popular substance, especially among male adolescents. We determined the prevalence of smokeless tobacco use and evaluated selected factors associated with it among 8,902 students in grades 7 through 12 in the Davis County, Utah, School District. The students responded anonymously in their classrooms to a 16-item self-reporting questionnaire. Results indicated that smokeless tobacco usage was predominately a male phenomenon in all grades and schools, as illustrated by prevalence rates "within the past week" for junior high school students (male: 15.0%; female: 1.1%). Modal responses regarding users' source of supply revealed "friends" as the leading source for junior high students (43.1%) and direct purchase for senior high students (62.2%). Peer usage or nonusage of smokeless tobacco was found to be directly and proportionately correlated with smokeless tobacco users' participation in the school activity designated "sports" for both junior high (39%) and senior high school students (36.2%). Subsequently, clinical evaluation of high school male athletes was undertaken. To our surprise, the rate of lesion detection among members of this group, previously judged to be the subjects most likely to use smokeless tobacco, fell far short of the anticipated rate. We believe the reason for the low rate may be the result of numerous efforts to educate students and coaches, the reinforcement of existing tobacco use policies by the Davis County School District, and the reiteration to smokeless tobacco vendors of the terms of the Utah laws relative to smokeless tobacco sales. This health-endangering behavior deserves a concerted educational thrust by health professional, parents, and teachers, with emphasis on prevention.

Necrotizing sialometaplasia obscuring an underlying malignancy: report of a case.

Necrotizing sialometaplasia poses many diagnostic problems, both clinically and microscopically. Caution had most frequently been urged for distinguishing between malignancy and NS, so as to avoid mutilating surgical treatment resulting from the misdiagnosis of a lesion that is benign and self-limiting. This case has been presented to alert the practitioner to the possibility that NS may obscure an underlying malignant disease process, possibly resulting in delays in referral or treatment. The exceedingly rapid growth of this mesenchymal neoplasm may have caused obstruction of the blood supply to the overlying mucosa and submucosa, thereby producing the ischemic alterations observed in the first biopsy specimens. Some of the difficulties encountered in the detection and diagnosis of neoplasms arising in the parapharyngeal space were discussed, and some previously published suggestions to aid in these efforts were reiterated.

Oral tissue alterations associated with the use of smokeless tobacco by teen-agers. Part I. Clinical findings.

The use of smokeless tobacco appears to be finding its way onto middle school, high school and college campuses as a socially acceptable and popular habit. Numerous reports in the literature have described the oral changes that appear to be associated with the use of smokeless tobacco in adults. Such information is unavailable for the lower age groups. A study was therefore undertaken to determine the prevalence and frequency of oral hard- and soft-tissue alterations associated with the use of smokeless tobacco in a teen-age population. High school students in grades 9 to 12 were evaluated on a random basis. From a total sample of 1,119 students, 117 users of smokeless tobacco were identified. Four distinct lesions associated with smokeless tobacco use were identified clinically: (1) hyperkeratotic or erythroplakic lesions of the oral mucosa, (2) gingival or periodontal inflammation, (3) a combination of oral mucosal lesions and periodontal inflammation, and (4) cervical erosion of the teeth. Among the smokeless tobacco users, 113 were boys and 4 were girls. Fifty-seven (48.7 percent) of the users had soft-tissue lesions and/or periodontal inflammation or erosion of dental hard tissues. Ninety-nine of the 117 users were Caucasian, 6 were Hispanic, 1 was black, 1 was Asian, 1 was an American Indian, and 6 failed to identify an ethnic origin. Use ranged from one to twenty "dips" per day, with an average time per dip of 30 minutes. Most users had been dipping for an average of 2 years, and twelve different tobacco brands were identified.

Adenomatoid odontogenic tumor: clinicopathologic and ultrastructural concepts.

Two cases of adenomatoid odontogenic tumor have been presented, along with a review of the literature. One tumor had a rather typical presentation, occurring in a 12-year-old in association with an impacted canine tooth. Subsequent electron microscopic evaluation of this case provided corroboration of other recently published findings. In this case there was a striking accumulation of what could have been secretory granules at the pole of the cell nearest a "duct-like" space. This cell had ultrastructural characteristics in common with a preameloblast. The second case occurred in a more unusual situation, the patient being a 32-year-old man, with the AOT developing in the mandible between the roots of the canine and first premolar. Both patients were treated successfully by simple enucleation of the lesion.

A comparison of the use of smokeless tobacco in rural and urban teenagers.

This paper compared the use of smokeless tobacco and its effects in rural and urban teenagers. A random sample of 445 subjects from rural Colorado were examined: 82.9 percent of the total sample were Caucasian, and 94.6 percent of those who used smokeless tobacco were Caucasian. This percentage supports the findings of an earlier urban study that the habit is predominantly one of male Caucasians. The average age of the users was 16.7 years, slightly older than in the urban study. Of the rural users, 62.5 percent had lesions of the oral tissues, compared with 48.7 percent lesional incidence in urban users. In both studies, those subjects with lesions had longer daily contact with smokeless tobacco, as well as a longer history of use than those without lesions. These are numerical averages that reflect great individual variations in susceptibility. The average duration of use for rural and urban users with lesions was almost the same; the development of lesions appears to be related to the length of daily exposure, which, on the average, was greater among rural users than urban users. Additionally, more than twice as many degree 3 lesions were found among users in the rural study. The habituating effects of nicotine and the influence of this substance on the future tobacco-usage patterns of youngsters who presently use smokeless tobacco are areas of concern. It is hoped that additional research will further delineate the scope of this current health problem.
