The effects of power toothbrushing on periodontal inflammation in a Canadian nursing home population: A randomized controlled trial.

OBJECTIVES: The aim of this study was to investigate whether twice-daily use of a rotating-oscillating power toothbrush (Oral-B Professional Care 1000™ ) in nursing home (NH) residents over a 6-week period, compared to usual care (UC), would reduce periodontal inflammation. METHODS: In this repeated measures single-blinded randomized controlled trial, 59 residents of one NH in Winnipeg, Canada, were randomized to receive either twice-daily tooth brushing with a rotating-oscillating power toothbrush (PB) or UC by caregivers. Consent was obtained from residents or their proxies. Participants had some natural teeth, periodontal inflammation, non-aggressive behaviour, no communicable diseases, were non-smokers and non-comatose. Outcomes were measured at baseline and 6 weeks, which included: inflammation (MGI, Lobene), bleeding (PBI, Loesche) and Plaque (Turesky). Comparisons of group changes in outcomes were analysed using an ANOVA with a repeated measure. RESULTS: Of 59 original study participants, one withdrew, one died prior to study commencement and three died before study completion. All oral parameters improved significantly for the remaining 54 residents over time (P<.0001), with no differences between groups. CONCLUSIONS: These results demonstrate that it is possible for caregivers to improve periodontal inflammation of residents over a 6-week period. Despite no significant group differences, periodontal inflammation of all study participants improved significantly, particularly in the reduction of bleeding, a direct measure of periodontal inflammation, which is a unique finding.

Dental hygienists in multidisciplinary health care.

The evolving roles and responsibilities of the dental hygiene profession are placing very different demands on its members. Collaboration with other health professionals will become necessary as the profession moves forward into more interdisciplinary settings. The purpose of this paper is to describe a recently published study involving collaboration between dental hygienists, physician assistants and physical therapists. Multidisciplinary teams comprised of representatives from each of the three professions participated in both a simulated problem-based case assessment and a real life patient assessment. Results showed favourable learning experiences by all three disciplines which could serve as a potential model for future multidiscipline projects. Collaborations between health professionals have the potential to enhance client care and ultimately improve their quality of life.

Geriatric education in dental hygiene programs.

This study examined the current status of geriatric curricula in dental hygiene programs in both the United States and Canada and was comprised of a twenty-six-item survey sent to dental hygiene programs. Responses (82 percent) revealed didactic requirements in 89 percent of programs and clinical requirements in 54.2 percent of programs surveyed. Mean didactic clock hours were ten (+/- 8.2), while clinical clock hours were 21.8 (+/- 27.5). Specific geriatric courses were found in only 18.8 percent of programs, while 81.2 percent integrated geriatrics with other coursework. Both clinical (98.8 percent) and didactic courses (81.5 percent) were taught primarily by dental hygiene faculty. Clinical experiences were primarily provided at extramural sites (79 percent). Half of schools surveyed (49.5 percent) felt their geriatric curriculum was less than optimal. The authors conclude that current levels of geriatric dental hygiene education may not meet the increasing demands of this growing population.

Effects of tartar-control dentifrice on tooth sensitivity: a pilot study.

PURPOSE: The purpose of this three-week, double-blind pilot study was to assess the effects of a tartar-control dentifrice on tooth sensitivity. METHOD: Fifty-six volunteer dental hygiene students completed a 14-item questionnaire regarding their oral health. Eighteen students were excluded from the study due to prior tooth sensitivity. Thirty-eight students were randomly assigned to either the experimental group using a tartar-control dentifrice (containing tetrapotassium pyrophosphate, PEG-6, disodium pyrophosphate, and tetrasodium pyrosulphate in a 5.0% soluble pyrophosphate formulation) or the control group using a regular dentifrice. Participants brushed for three weeks twice daily and then completed a post-treatment questionnaire, which included questions about tooth sensitivity. Differences between groups in reported sensitivity were measured by Fisher's Exact Test. RESULTS: Fisher's Exact Test revealed a statistically significant difference in sensitivity experienced by the experimental group compared to the control group (p < 0.05), which reported no sensitivity. The phi coefficient, used to examine the strength of the relationship between tartar control paste and tooth sensitivity, was found significant at p < 0.02. CONCLUSION: These findings suggest that patients may experience dentinal hypersensitivity when using the tartar-control toothpaste tested. Further long-term studies are required to test various brands of tartar-control dentifrice with a larger, more diverse sample for clinical measures of sensitivity.

Breaking down barriers: multidisciplinary education model.

A pilot project was implemented involving students from three disciplines: dental hygiene, physical therapy, and physician assistant. The purpose was to prepare students to work together in multidiscipline teams utilizing concepts of problem-based learning (PBL) on both simulated and real patients. The project was divided into three phases. Phase I introduced discipline specific information, team concepts, and PBL concepts. Phase II involved students working in multidisciplinary teams solving a simulated patient case in the PBL format. Phase III consisted of students working in small groups and on real patients, performing an extraoral/intraoral and periodontal examination, a problem oriented physical examination, and a neuromuscular assessment. Pre and posttest evaluation of Phase I revealed no difference in knowledge among the three disciplines. Of those students evaluating Phase II and III, 100% felt PBL was an effective means of presenting multidisciplinary material; 93% reported enhanced problem-solving; 98% indicated improvements in working in groups; and 98% felt they had learned more about each other's discipline. This model may provide a viable means to prepare interdisciplinary teams to work effectively together.

Effects of subgingival irrigation with chlorhexidine on the periodontal status of patients with HA-coated integral dental implants.

The purpose of this study was to examine the effect of chlorhexidine irrigation on the periodontal status of patients with HA-coated dental implants as measured by clinical, microbiological, and immunological measures. Thirty non-adjacent implants were randomly assigned to receive a one-time irrigation with either 0.12% chlorhexidine or sterile saline, or no irrigation. All parameters were measured at baseline, 2, 5, and 8 weeks. Results showed no significant differences between any treatment modalities at any time interval. A statistically significant decrease in probing depth (P < .05) occurred within the chlorhexidine and no-treatment groups at all time intervals compared to baseline.
