An oral hygiene brochure for your implant overdenture patients

Although there may not be a direct association between oral hygiene and implant failure, oral hygiene must be maintained around implants in the edentulous mouth. Bacterial plaque on dentures can act as a reservoir for pathogens that cause respiratory disease. Unfortunately, many edentulous patients have poor oral hygiene. In this article, we describe the development of a brochure to educate patients wearing mandibular overdentures supported by 2 implants as a supplement to the dentist"s verbal instructions. Dental literature and several specialists were consulted during preparation of the brochure, which contains photographs accompanying oral hygiene instructions. It was sent to 25 participants who were subsequently called and questioned regarding its content and their oral hygiene habits. The 24 respondents found the brochure useful; most reported that they would keep the brochure for future reference and that they learned something new about how to maintain their implants properly. No one found the brochure too long or unclear. Most participants read the brochure entirely, rather than skimming it. The brochure is available to all clinicians who wish to incorporate this tool into their implant overdenture therapeutic approach.     

Association of mutans streptococci between caregivers and their children

The purposes of this literature review were to: (1) review the sources of mutans streptococci (MS) colonization in children and the effect of MS levels of primary caregivers on children's MS colonization; and (2) evaluate studies examining interventions to reduce transmission of MS from caregivers to their children. Forty-six studies were reviewed. Strong evidence demonstrated that mothers are a primary source of MS colonization of their children. A few investigations showed other potential sources of children's MS colonization, notably fathers. The role of other factors influencing transmission, such as socioeconomic status (SES) and specific cultural or behavioral practices, are unclear. There were at least 12 reports of microbiological interventions to reduce transmission of MS from caregivers to their children. Even though most studies found a reduction of MS in the children and 2 showed significant caries reduction, these studies generally lock consistent findings regarding caries reduction, hove a small sample size and inadequate control groups, and lock blindness of investigators and subjects. The efficacy of microbiological approaches on the caregivers to reduce caries risk in children still needs to be established through more rigorously designed clinical trials.     

Utility of the Dental Aesthetic Index in Industrialized and Developing Countries

To be truly useful, an index must be applicable universally without modification. The data presented in this article support the use of the standard DAI without modification to assess need for orthodontic treatment in both developing and industrialized countries. When students from Thailand, Australia, the German Democratic Republic, and Native Americans residing on Indian reservations rated the same 25 occlusal stimuli (photographs of dental configurations) for dental aesthetics, their ratings of these stimuli when arranged in rank order were highly correlated with those of US students. These 25 occlusal stimuli were a subset of the original 200 occlusal stimuli used in deriving the standard DAI regression equation. This article presents data indicating that when a Native American DAI was derived based on Native American ratings of the same 200 occlusal stimuli used in deriving the standard DAI, the Native American DAI and the standard DAI had the same ten components (orthodontic measurements) and strikingly similar regression coefficients (weights). Further analysis indicated that the two equations were sufficiently similar to justify using the standard DAI to obtain DAI scores on Native Americans and to estimate the relative social acceptability of their dental aesthetics. If ratings for dental aesthetics for the full set of 200 stimuli were available for each of the countries where only 25 were rated, we expect that, as in the case of Native Americans, a country-specific DAI, if computed, would be sufficiently similar to the standard DAI that no modification would be needed to allow use of the standard DAI in that country.(ABSTRACT TRUNCATED AT 250 WORDS)     

Infant oral health education for pediatric and family practice residents

PURPOSE: The purpose of this study was to investigate whether an infant oral health curriculum implemented in pediatric and family medicine residency programs could improve physicians' oral health knowledge and practice behaviors and promote the age 1 dental visit. METHODS: Residents and faculty members completed a baseline current practices survey and knowledge test before receiving a 1- or 2-hour training session followed by a knowledge post-test. Existing well child care forms were updated with oral health prompts to reinforce newly learned skills. At 1-year follow-up (1 YFU), participants completed a current practices survey and knowledge test. In addition to the residency programs, medical students and advanced practice registered nurses participated in baseline data collection, training, and immediate posttest data collection. RESULTS: A total of 245 people participated, with 78% trained in person and 22% trained via the Web. Of these, 120 were the targeted residents and faculty-of whom 82% completed the 1 YFU. Practice behaviors improved from baseline to 1 YFU, with only 28% of practitioners at baseline referring children to the dentist at age 1, compared to 73% at 1 YFU (P<.05). Knowledge scores were greater at 1 YFU than at baseline (P<.05), and the mode of training showed no difference in knowledge outcomes. Knowledge and prescribing practices regarding fluoride were poor at baseline and showed limited improvement at 1 YFU. CONCLUSIONS: An infant oral health education program can improve physicians' oral health knowledge and behaviors, particularly regarding promoting the age 1 dental visit. Behavior changes regarding fluoride prescribing, however, appear harder to achieve. Web-based training had similar success to in-person training.     

Diabetes Mellitus and Disturbances in Brain Connectivity: A Bidirectional Relationship?

Diabetes mellitus (DM) is associated with deficits across multiple cognitive domains. The observed impairments in cognitive function are hypothesized to be subserved by alterations in brain structure and function. Several lines of evidence indicate that alterations in glial integrity and function, as well as abnormal synchrony within brain circuits and associated networks, are observed in adults with DM. Microangiopathy and alterations in insulin homeostasis appear to be principal effector systems, although a unitary explanation subsuming the complex etiopathology of white matter in DM is unavailable. A contemporary model of disease pathophysiology for several mental disorders, including but not limited to mood disorders, posits abnormalities in the synchronization of cellular systems in circuits. The observation that similar abnormalities occur in diabetic populations provides the basis for hypothesizing the convergence of pathoetiological factors. Herein, we propose that abnormal structure, function and chemical composition as well as synchrony within and between circuits is an accompaniment of DM and is shared in common with several mental disorders.
