“…It has been suggested that the oropharyngeal bacterial flora is a reservoir for respiratory pathogens, and patients with poor oral hygiene have a higher risk of respiratory disease Scannapieco et al, 1992;Scannapieco and Mylotte, 1996 . It has been also reported that oral health care for elderly patients in nursing homes reduces the incidence of bacterial pneumonia Yoneyama et al, 1996;Yoneyama et al, 1999;Ishikawa et al, 2008 .

To clarify the availability of the dielectrophoretic impedance measurement DEPIM system as the evaluator for oral care, we evaluated the usefulness of DEPIM system by comparison with the standard plate counting SPC method. First, the relationship between the DEPIM results and bacterial concentration measured by SPC was clarified. Next, the measurement of the microorganism number in a mixed suspension was evaluated with DEPIM and SPC. The bacterial counts with DEPIM strongly correlated with those with SPC r 2 =0.633-0.997 and this correlation was also shown in the measurement of a mixed bacterial suspension ranging from 10 5 to 10 8 cfu/ml of two bacterial species. Moreover, the experiments using dissociating enzymes to eliminate the influence of the size of the bacterial aggregates demonstrated that the microbial measurement results with DEPIM are unaffected by bacterial aggregates. This study demonstrated that bacterial counts with DEPIM strongly correlated with those with SPC and were unaffected by bacterial aggregates.Key words Dielectrophoresis / Impedance / Aspiration pneumonia/Oral care / Rapid microbial quantification.Biocontrol Science, 2014, Vol. 19, No. 1, 45 49 bacteria from clinical samples with the SPC method takes a few days due to its culture-based approach.To evaluate the efficacy of professional mechanical oral cleaning, the development of a quick and easy bacterial counter that can be used at the bedside would b e b e n e f i c i a l .

“…Professional oral care decreases the microbial counts of the total oropharynx and can be an important strategy to prevent aspiration pneumonia (Ishikawa et al 2008). In our study, all patients were instructed by either the dentist or the dental hygienist to improve oral hygiene to keep the level of O'Leary plaque control < 20%.…”

Prospective Study of Dental Intervention for Hematopoietic Malignancy

et al. 2014

Various chemotherapeutic agents used in patients with hematopoietic malignancy cause serious side effects, including myelosuppression and immunosuppression. Immunosuppression makes patients more susceptible to infection, resulting in an increased risk of infectious complications, including the development of severe septicemia that may be life-threatening. It is necessary for dental staff to be familiar with an appropriate protocol in such cases and to share information about the chemotherapy with a hematologist. To verify the effectiveness of our dental intervention protocol, we conducted a prospective study on the incidence of complications for each myelosuppressive grade of chemotherapy in patients with hematopoietic malignancy. We compared the incidence of complications between treatment P (patients who finished all the dental treatments according to the protocol) and treatment Q (patients who did not) per grade (A, B, C, D) and incidence of systemic or oral findings. We also compared the incidence of oral complication related to the residual teeth between first chemo (patients who were undergoing chemotherapy for the first time) and prior chemo (not the first time). There were significant differences in inflammatory complications between treatment P and treatment Q. We found that both systemic and oral inflammatory complications increased with higher-grade myelosuppressive chemotherapy. Additionally, there was a significant difference between the incidence of oral complications related to the residual teeth between first chemo and prior chemo. Complete implementation of the dental intervention protocol was associated with fewer oral and systemic infectious and inflammatory complications in patients with hematopoietic malignancies undergoing chemotherapy. The incidence of oral and systemic complications also increased with grade of chemotherapy. These results support the validity of our dental intervention protocol. We should pay close attention to the oral state of de novo hematopoietic malignancy patients.

Background: The purpose of this study was to implement a collaborative oral health project and evaluate its effectiveness for caregivers in an assisted-living facility. An interdisciplinary study was conducted by nursing and dental hygiene faculty. Methods:A quasi-experimental design was utilized with a pre-post treatment format. Pre-and post-treatment scores were analyzed from a convenience sample of 13 caregivers in an assisted-living facility. The information addressed oral care assessments, interventions, evaluation and referral guidelines.Results: Post-treatment scores were significantly higher than pre-treatment scores (p=.002). The results indicate the collaborative teaching project was effective increasing knowledge of assisted-living caregivers regarding oral hygiene practices for older adults.Conclusions: Based on these findings the results indicate collaborative oral health care teaching project was effective in increasing caregiver oral hygiene knowledge. It was concluded that the collaborative instruction was effective. Other considerations included positive outcomes on a follow-up survey assessment of caregivers and assisted-living management regarding utilization of new information that had been presented.
