Emilson CG, Klock B, Sanford GB. Microbial flora associated with presence of root surface caries in periodontally treated patients. Scand J Dent Res 1988; 96: 40-9.Abstract -Examination of saliva and dentai plaqtie was carried out in 35 adults who had been treated for periodontal disease 3 yr earlier. Plaque samples were collected from approximal and btiiccal sound and carions root surfaces. The satnples were analyzed for the presence and proportions of members of Streptococcus, Lactobacillus and Actinomyces. The results showed a low prevalence of root surface earies and a low level of salivary mutans streptococci and lactobacilli. From subjects with root caries there was a not statistically significant tendency to higher proportional levels of mutans streptococci in plaque from carious root surfaces than from caries-free surfaces. An inverse significant relationship between noncarious and carious root surfaces was noted for S. sanguis. The population of A. viscosus and A. naeslundii was similar in plaque samples from sound and carious sites but showed elevated levels in the subjects with five or more new root surface lesions.
One of the challenges facing international healthcare missionaries is that of maintaining up-to-date knowledge and staying current with professional certification. Since 1978, annual programs by the Christian Medical and Dental Associations have offered professional continuing education to thousands of US healthcare professionals serving as missionaries in the regions of Africa, Asia, and, in more recent years, globally. In addition, conference programming is designed to prepare, train, and support healthcare missionaries to, in turn, serve as educators in their places of ministry. The program is designed for both professional education and personal encouragement. Utilizing historical documents from program facilitation and interviews from those involved with its implementation, this paper describes the history, vision, and favorable quantitative growth and qualitative impact on participants. The program continues to grow as healthcare missionaries are educated near their places of service, while reinforcing their own roles as educators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
