Abstract: Computer-aided learning (CAL) offers enormous potential in disseminating oral health care information to patients and caregivers. The effectiveness of CAL, however, remains unclear. Objectives: The purpose of this study was to systematically review published evidence on the effectiveness of CAL in disseminating oral health care information to patients and caregivers. Materials and Methods: A structured comprehensive search was undertaken among 7 electronic databases (PUBMED, CINAHL Plus, EMBASE, SCOPUS, WEB of SCIENCE, the Cochrane Library, and PsycINFO) to identify relevant studies. Randomized controlled trials (RCTs) and observational studies were included in this review. Papers were screened by 2 independent reviewers, and studies that met the inclusion criteria were selected for further assessment. Results: A total of 2915 papers were screened, and full texts of 53 potentially relevant papers (κ = 0.885) were retrieved. A total of 5 studies that met the inclusion criteria (1 RCT, 1 quasi-experimental study, and 3 post-intervention studies) were identified. Outcome measures included knowledge, attitude, behavior, and oral health. Significant improvements in clinical oral health parameters (P & .05) and knowledge/attitudes (P & .001) were reported in 2 of the studies. The 3 remaining studies reported improved oral health behaviors and confidence. Conclusion: There is a limited number of studies which have examined the effectiveness of CAL interventions for oral health care among patients and caregivers. Synthesis of the data suggests that CAL has positive impacts on knowledge, attitude, behavior, and oral health. Further high- quality studies on the effectiveness of CAL in promoting oral health are warranted.

Abstract: To evaluate the presence of oral opportunistic pathogens among stroke survivors, both before and after oral health care interventions. A multicenter randomized clinical trial was conducted on hospitalized stroke survivors. Those in the control group were given standard care of oral hygiene (a manual toothbrush and toothpaste), whereas those in the test group were given intense care of oral hygiene (a powered toothbrush and 1% chlorhexidine oral gel). Oral clinical assessments were carried out, and microbiological s les were collected, using concentrated oral rinse s les at 3 time points: baseline, 3 months, and 6 months. The prevalence of oral yeast was significantly reduced in the test group at 6 months (P < .05), but no significant difference was observed over time. A significant reduction was observed in the prevalence of Staphylococcus aureus (P < .01) and aerobic and facultative gram-negative bacilli over time (P < .05), but there were no significant differences noted between groups at 6 months. Candida albicans and Klebsiella pneumoniae were the prominent pathogens determined throughout the trial. Kluyvera strains have also been isolated from this cohort. Oral hygiene intervention using a powered tooth brush and 1% chlorhexidine oral gel was effective in reducing the prevalence of oral opportunistic pathogens.

Abstract: This systematic review aimed to provide a synthesis of the evidence relating to how the provision of vitamin D supplements influences oral health status. An electronic database search was performed across six databases using a standardised search strategy. The PICO framework (Population, Intervention, Comparison, Outcome) was used to define the review question. The screening and selection followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses process (PRISMA). The quality of reporting was assessed using Consolidated Standards of Reporting Trials (CONSORT) guidelines, and the bias was assessed using the revised Cochrane tool RoB2. A total of 1812 studies were retrieved. 1427 studies were excluded due to unmet inclusion criteria. Full texts of seventy-five potential studies were retrieved and ultimately six studies met the inclusion criteria. There were limitations in the quality of reporting of studies (between 49 % and 73 %). 70 % of the risk of bias items were in the low risks category. Vitamin D interventions varied with respect to dosage and duration. Qualitative syntheses identified significantly better oral health outcomes. Heterogeneity of study design, intervention and outcomes precluded quantitative synthesis. Few clinical trials investigated the effect of vitamin D supplementation on oral health. There is considerable heterogeneity among studies interventions and oral health outcomes. Quality of reporting of studies has limitations and there is evidence of study biases. Nonetheless, qualitative synthesis of the evidence suggests that vitamin D supplements improve oral health outcomes, particularly periodontal health. Calcium may also play a significant role. Further high-quality trials are required of comparable vitamin D supplements with similar oral health outcomes focused to inform quantitative synthesis of the evidence.

Abstract: Maintaining good oral hygiene is important following stroke. This study aimed to evaluate the effectiveness of two oral health promotion (OHP) programmes to reduce dental plaque levels following stroke. A multi-centre randomised clinical control trial was conducted among patients hospitalised following stroke in Malaysia. Patients were randomly allocated to two OHP groups: (i) control group who received the conventional method for plaque control-daily manual tooth brushing with a standardised commercial toothpaste, (ii) test group-who received an intense method for plaque control-daily powered tooth brushing with 1% Chlorhexidine gel. Oral health assessments were performed at baseline, at 3 months and 6 months post-intervention. Within- and between-group changes in dental plaque were assessed over time. Regression analyses were conducted on dental plaque levels at 6 months controlling for OHP group, medical, dental and socio-demographic status. The retention rate was 62.7% (54 of 86 subjects). Significant within-group changes of dental plaque levels were evident among the test group (P < .001) and the control group (P .05). Regression analyses identified that baseline plaque levels (adjusted ß = 0.79, P < .001) and baseline functional dependency level (adjusted ß = -0.34, P < .05) were associated with dental plaques levels at the end of the trial (6 months). Both, "Conventional" and "Intense" oral health promotion programmes may successfully reduce dental plaque during stroke rehabilitation and are of comparable effectiveness. Baseline dental plaque levels and functional dependency level were key factors associated with dental plaque levels at follow-up at 6 months.

Abstract: This study aimed to examine "intention to" and "performance of" oral hygiene care to stroke patients using the Theory of Planned Behavior. A large scale survey of 13 centers in Malaysia was conducted involving 806 nurses in relation to oral hygiene care intentions and practices. In addition, information on personal and environmental factors was collected. The response rate was 95.6% (778/806). The domains of the Theory of Planned Behavior were significantly associated with general intention to perform oral hygiene care: attitudes (β = 0.21, p < 0.001), subjective norms (β = 0.38, p < 0.001), perceived behavior control (β = 0.04, p < 0.001) after controlling for personal and environmental factors. Approximately two-thirds (63.4%, 493) reported the performance of some form of oral hygiene care for patients. This behavior was associated with general intention scores (OR =1.13, 95%CI =1.05-1.22, p <0.01), controlling for other factors. Knowledge scores, training, access to oral hygiene guidelines and kits, as well as working ward type were identified as key factors associated with intention and practice of oral hygiene care. The Theory of Planned Behavior provides understanding of "intention to" and "performance of" oral hygiene care to stroke patients. Several provider and environmental factors were also associated with intentions and practices. This has implications for understanding and improving the implementation of oral hygiene care in stroke rehabilitation. Implications for Rehabilitation Oral hygiene care is crucial for stroke patients as it can prevent oral health problems and potentially life threatening events (such as aspiration pneumonia). Despite oral hygiene care being relative simple to perform, it is often neglected during stroke rehabilitation. A large-scale national survey was conducted to understand "intentions to" and "performance of" oral hygiene care to stroke patients using the Theory of Planned Behavior social cognition model. These study findings may have implications and use in promoting oral hygiene care to stroke patients:i) by understanding the pathways and influences to perform oral hygiene care.ii) to conduct health promotion and health education based on behavioral models such as Theory of Planned Behavior.

Abstract: To investigate oral health knowledge for stroke care and the clinical practices performed for oral hygiene care in Malaysia. Oral hygiene care following stroke is important as the mouth can act as a reservoir for opportunistic infections that can lead to aspirational pneumonia. A national cross-sectional survey was conducted in Malaysia among public hospitals where specialist stroke rehabilitation care is provided. All (16) hospitals were invited to participate, and site visits were conducted. A standardised questionnaire was employed to determine nurses' oral health knowledge for stroke care and existing clinical practices for oral hygiene care. Variations in oral health knowledge and clinical practices for oral hygiene care were examined. Questionnaires were completed by 806 nurses across 13 hospitals. Oral health knowledge scores varied among the nurses their mean score was 3.7 (SD 1.1) out of a possible 5.0. Approximately two-thirds (63.6%, n = 513) reported that some form of "mouth cleaning" was performed for stroke patients routinely. However, only a third (38.3%, n = 309) reported to perform or assist with the clinical practice of oral hygiene care daily. Their oral health knowledge of stroke care was associated with clinical practices for oral hygiene care (p < .001). The clinical practice of providing oral hygiene care is less than ideal, and there are deficiencies in oral health knowledge for stroke care. Oral health knowledge was associated with clinical practice of providing oral hygiene care. This has implications for training and integrating oral hygiene care within stroke rehabilitation.

Abstract: To investigate, using a validated questionnaire, the teaching of removable partial dentures (RPDs) in dental schools of Malaysia. A validated questionnaire to investigating trends in the teaching of RPDs in dental schools in Oceania was emailed (in English version form) to Heads of Restorative/Prosthodontics/course coordinators in the 13 dental schools in Malaysia. Follow-up reminders were sent and participants were given six weeks to complete and return the questionnaire. Data was entered into an Excel spreadsheet and results compiled and analyzed. Completed questionnaires were received from 13 dental school - a 100% response rate. All schools (n = 13) provided a preclinical technical course in RPD design. In most schools (n = 9, 69.2%), course work was supervised by senior lecturers while rest of the institutions made use of associate professor rofessors. There were significant differences (p<0.05) between dental schools in terms of the contact hours dedicated to preclinical teaching. Students received an average of 62 h of instruction. Didactic instruction was the primary focus with practical (78 h) and didactic teaching (32 h). All dental schools (n = 13) provided practical surveyor design teaching (8 h). The staff student ratio for formal lectures (1:61), tutorials (1:29) and lab demonstrations (1:12) were recorded. Majority of the schools (n = 11, 84.6%) employed paired teaching in clinical sessions. All schools (n = 13, 100%) emphasized on increased teaching of RPD design and prescription writing in future clinical RPD courses. Teaching of RPDs in Malaysia may be considered sufficient and comparable to the teaching in other parts of the world. Whilst the teaching of partial dentures at Dental Schools in Malaysia provides the core competencies involved in partial denture design and construction based on sound fundamental, scientific principles they should address the challenges of teaching partial dentures and other areas of dental education including improving working conditions for dental professionals.

Abstract: To review the effectiveness of antiseptic oral sprays on oral health. Three electronic databases (PubMed, Cochrane Library and Web of Science) were systematically searched to identify relevant studies. Only randomized controlled trials (RCTs) comparing the effect of oral sprays to placebo/control spray or mouthrinse on dental plaque and gingival inflammation were included. Among a total of 996 papers, 20 effective studies fulfilled the selection criteria, and 8 studies were suitable for inclusion in meta-analyses. A meta-analysis of three studies using a 0.2% chlorhexidine (CHX) spray intervention, without prophylaxis at baseline, showed reductions in Plaque Index (PI) (Silness and Löe) and Gingival Index (GI) (Silness and Löe) scores of 0.74 (95% CI: -1.03 to -0.45) and 0.22 (95% CI: -0.38 to -0.06), respectively. Five studies provided a prophylaxis for subjects before study initiation. Three of these five studies used 0.2% CHX spray. A meta-analysis demonstrated an increase of 0.18 (95% CI: -0.01 to 0.37) in PI (Silness and Löe) scores. Two RCTs compared 0.12% and 0.2% CHX spray, and a meta-analysis showed increases of 1.71 (95% CI: 1.27 to 2.14) and 1.58 (95% CI: 1.23 to 1.93), respectively, in PI (Quigley and Hein) scores. Of the RCTs not amenable to meta-analysis, eight studies reported significant improvements in PI and GI scores. Available evidence suggests that oral sprays are an acceptable delivery method for antiseptic agents. Further high-quality studies are warranted to determine the effectiveness of alternative chemotherapeutic agents delivered via oral sprays on oral health.
