Survival of Black Colleges from a Dental Perspective

If we are to achieve health for all in the US by the year 2000, as proposed by the World Health Organization (WHO), we must consider dental health needs as a component of total health. The failure to address dental health needs has reached a crisis level, particularly in the black and underserved communities throughout the nation

Tissue response to intraosseous implants in albino rats

The purpose of this study was to determine changes in the soft or hard tissue surrounding isolated intraosseous implants. Implant screws were machined to uniform dimension from three gold-base alloys, two cobalt-base alloys, two stainless steel, and one platinum-iridium alloy. Adult, male albino rats (375 to 475 grams) were used. Perforations were made on the lateral aspect of the femur bone by means of friction-grip, round carbide burs, and screws were placed loosely in the perforations. Each animal received one implant only. Sham-operated controls were included for each group. Animals were killed at intervals of 1, 2, 3, 4, and 5 weeks. Longitudinal sections of the bone (with respect to the longitudinal axis of the implant) were stained with hematoxylin and eosin. A layer of connective tissue was present surrounding all implants. This capsule differed according to the type of metal and the duration of implantation. The formation and maturation of new bone appeared to have begun in the spiral adjacent to the periosteal end of the screw and to have proceeded toward the apex of the screw. Implants were completely encapsulated by newly formed bone at the end of the fourth week. The rate of formation of bone appeared to be higher in the control wounds. On the basis of the amount of bone formed around the implants, cobalt-base and stainless steel alloys were found to be more suitable for implantation than the other materials tested. © 1974

Components of effective outreach and recruitment programs for underrepresented minority and low-income dental students

Dental schools in the Pipeline, Profession, and Practice: Community-Based Dental Education program that increased the number of underrepresented minority (URM) and low-income (LI) students in their predoctoral programs used focused approaches in their outreach, recruitment, and retention initiatives. Various combinations of approaches were used by the fifteen schools that received funding during Phase I of the program, which spanned 2003 to 2007. URM enrollment in the Pipeline schools increased from 184 students in 2003 to 246 in 2007. These enrollment numbers represent 16 and 20 percent of the first-year class in the Pipeline schools in 2003 and 2007, respectively. If the historically minority-serving institutions-Howard University College of Dentistry and Meharry Medical College School of Dentistry-are removed from these totals, the numbers changed from 100 in 2003 to 144 in 2007, representing 10 and 13 percent of the first-year classes. This chapter describes the approaches used by the fifteen Pipeline schools to increase the number of URM and LI students recruited to and enrolled in their predoctoral programs. It describes the internal infrastructural and organizational approaches these dental schools used to increase awareness about oral health careers among URM and LI students and to recruit applicants from these populations to their educational programs. The effective partnerships and collaborations these dental schools established with each other and external stakeholders to bolster their career outreach and recruitment efforts and some of the informal efforts that supported increased diversity are also examined

Long-range effects of Ivalon sponge containing isobutyl cyanoacrylates on rat tissue. A quantitative planimetric study

This study on seventy rats was undertaken to determine the long-range effects of Ivalon sponge containing isobutyl cyanoacrylates (IBC). Histologic examination revealed that the IBC sponge was well tolerated by the connective tissue. IBC sponge was most effective during the first 2 weeks of healing. At observation periods of 1 and 2 weeks, the percentage values for connective tissue formed in IBC-treated animals were 2.02 and 1.58 times higher than those in the untreated animals. © 1975
