A comparison of dental restoration outcomes after placement by restorative function auxiliaries versus dentists.

OBJECTIVES: To compare the outcomes of restorations placed by restorative function auxiliaries (RFAs) with those placed by dentists. METHODS: Between July 1, 2007, and June 30, 2008, we matched 455 restorations placed by RFAs working at HealthPartners Dental Group with the same number placed by dentists. Restorations were matched by tooth number, American Dental Association procedure code, and patient age-group. RESULTS: Of 910 restorations, 17 (1.9 percent) had problems potentially related to the filling or crown placement during the first year. Problem rates were not significantly different (p = 0.33) for restorations placed by RFAs (1.3 percent, 6 of 455) and those placed by dentists (2.4 percent, 11 of 455). CONCLUSIONS: There was no significant difference in problem rates for restorations placed by RFAs versus those placed by dentists. This finding may free dentists to handle more difficult cases, alleviating some of the pressures of daily practice and meeting the need for improved access.

Oral health program preferences among pregnant women in a managed care organization.

OBJECTIVE: The purpose of the study was to understand the oral health information preferences of pregnant women and new mothers. METHODS: This study was conducted at a Minnesota managed care organization. A random sample of 250 women with public program insurance and 250 privately insured women was selected from the population of pregnant women in the claims systems. The study consisted of a mailed survey and phone contact to nonresponders. The analytic sample consisted of 123 public-pay and 127 private-pay respondents. Descriptive statistics summarize the preferences for oral health care topics. RESULTS: Receiving information by mail was preferred by both groups. Women favored information concerning infant-specific oral health more than information on both mother and infant oral health. While public-pay respondents had more enthusiasm for many topics, the topic preference rankings within each sample were similar. CONCLUSION: Similarities in program preferences suggest that common interventions could be designed that would appeal to both groups without extensive tailoring.

Evaluating strategies and costs to recruit smokeless tobacco users.

We recruited smokeless tobacco users throughout Minnesota to participate in a trial testing telephone counseling versus a written self-help manual for cessation. This paper describes the recruitment strategies applied on a state-wide basis. We established a recruitment tracking system to monitor weekly rates of screened callers and returned consents, allowing us to adjust future recruitment efforts. Screening was completed with 783 callers, with 406 subjects enrolled. Overall 44% of initial contacts and 52% of those screened enrolled in the study. The overall average cost per consented subject was $99. Sports talk radio, small print ads, and newspaper articles based on press releases were consistently effective channels for recruitment. The overall cost was expensive but reflected the geographic diversity of recruitment and the prevalence of oral snuff use.

A randomized controlled trial of Telephone Counseling with smokeless tobacco users: the ChewFree Minnesota study.

Although a considerable body of evidence supports telephone quit lines for smoking cessation, much less is known about the effectiveness of proactive Telephone Counseling with smokeless tobacco (ST) users. We conducted a randomized controlled trial comparing Telephone Counseling with the distribution of a self-help manual for ST cessation. We recruited 406 adult ST users throughout the state of Minnesota and randomized them to receive either: (a) a self-help manual (Manual only) or (b) a self-help manual plus proactive telephone-based cessation counseling (Telephone Counseling). The telephone-based treatment included up to four calls in support of quitting, and personalized various cognitive and behavioral strategies that are generally considered effective in tobacco cessation (such as setting a quit date, examining patterns of use, developing stress reduction skills, avoiding known triggers to use). Participants were surveyed by phone at 3 and 6 months to assess both point prevalence and continued abstinence. Prolonged abstinence from all tobacco was 6.8% and 30.9% (p < .001) at 3 months and 9.8% and 30.9% (p < .001) at 6 months in Manual only and Telephone Counseling, respectively. We found older age, lower dependency, and increased readiness predicted quitting success. Proactive telephone-based counseling is an effective strategy for improving cessation rates among ST users. Future research should determine the components contributing to the intervention success.
