METHODS: This study is a pragmatic, cluster-randomised, parallel-group, matched pair, controlled trial with blinded outcome assessment. Randomisation is performed using a computer-generated table with a 1:1 allocation comparing the SIMSP and the POHP involving 28 preschools in the Kampar district, Perak, Malaysia. The intervention consists of preschool visits by a group of dental therapists, in-class oral health lessons and daily toothbrushing conducted by class teacher, child home toothbrushing supervised by parents, and infographic oral health messages to parents. The control consists of the existing POHP that involves preschool visits by a group of dental therapists only. The trial lasts for 6 months. Primary outcome variable is the mean plaque score change after 6 months. To determine the feasibility of the SIMSP, a process evaluation will be conducted using the perspectives of dental therapists, teachers, and parents on the appropriateness, effectiveness, facilitators, and barriers to the SIMSP implementation as well as an audit trail to assess the trial intervention.
DISCUSSION: Cluster randomisation may lead to a random effect and cluster selection bias. These factors will be accounted for when analysing the data and interpreting the outcomes. The effectiveness of the SIMSP will be evaluated by comparing the results with those of the POHP.

MATERIAL AND METHODS: In this prospective study, 20 IFPP (mean age 47.0; SD 12.9 years) and 28 ISOD (mean age 61.5; SD 9.1 years) patients received 2 mandibular implants. Metal ceramic nonsplinted fixed prostheses were provided in IFPP group, while in ISOD group, the mandibular overdentures were retained by nonsplinted attachments. Patients rated their oral health-related quality of life using OHIP-14 Malaysian version at baseline (T0), 2-3 months (T1) and 1 year (T2) postimplant treatment. Mean OHIP-14 for total and domain scores between groups and intervals was analysed using repeated-measures ANOVA and t-test. Mann-Whitney and Wilcoxon signed-rank tests were used for the comparison of mean score change and effect size, while the association between pre- and post-treatment scores was determined using multivariate linear regression modelling.
RESULTS: The total OHIP and domain scores before implant treatment were significantly higher (lower OHRQoL) in IFPP than in ISOD groups, except for physical pain where this domain showed similar impact in both groups. Postimplant scores between groups at T1 and T2 showed no significant difference. The mean score changes at T0-T1 and T0-T2 for total OHIP-14 and domains were significantly greater in IFPP except in the domains of physical pain and disability which showed no difference. Large effect size (ES) was observed for total OHIP-14 in IFPP while moderate in ISOD. Improved OHRQoL was dependent on the treatment group and pretreatment score.
CONCLUSION: Improvement in OHRQoL occurred following both mandibular implant-supported overdentures and implant fixed partial prostheses.
OBJECTIVES: To compare manual and powered toothbrushes in everyday use, by people of any age, in relation to the removal of plaque, the health of the gingivae, staining and calculus, dependability, adverse effects and cost.
SEARCH METHODS: We searched the following electronic databases: the Cochrane Oral Health Group's Trials Register (to 23 January 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE via OVID (1946 to 23 January 2014), EMBASE via OVID (1980 to 23 January 2014) and CINAHL via EBSCO (1980 to 23 January 2014). We searched the US National Institutes of Health Trials Register and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases.
SELECTION CRITERIA: Randomised controlled trials of at least four weeks of unsupervised powered toothbrushing versus manual toothbrushing for oral health in children and adults.
DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by The Cochrane Collaboration. Random-effects models were used provided there were four or more studies included in the meta-analysis, otherwise fixed-effect models were used. Data were classed as short term (one to three months) and long term (greater than three months).
MAIN RESULTS: Fifty-six trials met the inclusion criteria; 51 trials involving 4624 participants provided data for meta-analysis. Five trials were at low risk of bias, five at high and 46 at unclear risk of bias.There is moderate quality evidence that powered toothbrushes provide a statistically significant benefit compared with manual toothbrushes with regard to the reduction of plaque in both the short term (standardised mean difference (SMD) -0.50 (95% confidence interval (CI) -0.70 to -0.31); 40 trials, n = 2871) and long term (SMD -0.47 (95% CI -0.82 to -0.11; 14 trials, n = 978). These results correspond to an 11% reduction in plaque for the Quigley Hein index (Turesky) in the short term and 21% reduction long term. Both meta-analyses showed high levels of heterogeneity (I(2) = 83% and 86% respectively) that was not explained by the different powered toothbrush type subgroups.With regard to gingivitis, there is moderate quality evidence that powered toothbrushes again provide a statistically significant benefit when compared with manual toothbrushes both in the short term (SMD -0.43 (95% CI -0.60 to -0.25); 44 trials, n = 3345) and long term (SMD -0.21 (95% CI -0.31 to -0.12); 16 trials, n = 1645). This corresponds to a 6% and 11% reduction in gingivitis for the Löe and Silness index respectively. Both meta-analyses showed high levels of heterogeneity (I(2) = 82% and 51% respectively) that was not explained by the different powered toothbrush type subgroups.The number of trials for each type of powered toothbrush varied: side to side (10 trials), counter oscillation (five trials), rotation oscillation (27 trials), circular (two trials), ultrasonic (seven trials), ionic (four trials) and unknown (five trials). The greatest body of evidence was for rotation oscillation brushes which demonstrated a statistically significant reduction in plaque and gingivitis at both time points.
AUTHORS' CONCLUSIONS: Powered toothbrushes reduce plaque and gingivitis more than manual toothbrushing in the short and long term. The clinical importance of these findings remains unclear. Observation of methodological guidelines and greater standardisation of design would benefit both future trials and meta-analyses.Cost, reliability and side effects were inconsistently reported. Any reported side effects were localised and only temporary.
METHODS: The Khadijah Rohani's Readability Formula (KRRF) and Suitability Assessment of Materials (SAM) instrument were used to assess the readability and suitability of the pamphlets respectively. All 23 Bahasa Malaysia pamphlets retrieved from the official portal of OHP on the 31st January 2019 were assessed for suitability. However, only five pamphlets were found to be eligible for readability assessment because the KRRF, the single formula available for Bahasa Malaysia text is applicable only for materials with 300 words or more. The readability is interpreted based on the level of formal education in Malaysia.
RESULTS: All pamphlets achieved superior suitability rating with a minimum and maximum score of 75% and 95% respectively. However, a few pamphlets did not fulfil SAM superior and adequate criteria for the following factors and were rated not suitable: did not include summary (73.9%), have few or no headers (4.3%), did not use captions to explain graphics (17.4%), and did not provide interactive learning (21.7%). Readability of the pamphlets eligible for assessment ranged from primary six to secondary three.
CONCLUSIONS: OHE pamphlets produced by the MOH are readable by most Malaysians. Most pamphlets are generally suitable for the intended audience although a few performed poorly in several areas.
METHODS: We recruited long-stay inpatients with schizophrenia from June to October 2014. Four dental specialists assessed oral health using the decayed-missing-filled teeth index, the Community Periodontal Index of Treatment Needs and the Debris Index of the Simplified Oral Hygiene Index. Results were compared with the 2010 Oral Health survey of the general Malaysian population.
RESULTS: A total of 543 patients participated (66.7% males, 33.3% females; mean age = 54.8 years [standard deviation = 16.0]) with a mean illness duration of 18.4 years (standard deviation = 17.1). The mean decayed-missing-filled teeth was 20.5 (standard deviation = 9.9), almost double that of the general population (11.7). Higher decayed-missing-filled teeth scores were associated with both older age (p oral health is most marked for dental decay. Possible interventions include oral health assessments using standard checklists designed for non-dental personnel, help with oral hygiene, management of iatrogenic dry mouth and early dental referral.
MATERIALS AND METHODS: A total of 154 first-time mothers in the third trimester of pregnancy who attended two health clinics in the state of Sarawak, Malaysia for antenatal care participated in this cross-sectional study. A structured selfadministered questionnaire was used to measure the variables of interest.
RESULTS: Most mothers could correctly identify the aetiological factors of dental caries and strategies for preventing the disease in children. However, a substantial portion could not identify certain cariogenic and noncariogenic foods or drinks. Most pregnant women have appropriate attitudes towards children's oral health although some showed unfavourable attitude about care of primary teeth. Women who were older and had attended a talk on children's oral health were more likely to have higher mean knowledge score than their respective counterparts, and higher mean knowledge score was associated with higher mean attitude score.
CONCLUSION: Most first-time mothers in this study had correct knowledge and favourable attitude about children's oral health, although misunderstandings and misperceptions in several issues were also common. Significant association found between experience of attending oral health talk and oral health knowledge, and between oral health knowledge and attitude, substantiate the importance of an educational intervention program to optimise the mothers' roles in caries prevention in children.
MATERIALS AND METHODS: Sixty women, divided into equal groups of PCOS and healthy patients, were clinically examined for periodontal parameters like probing depth (PD), plaque index (PI), modified gingival index (mGI), and bleeding on probing (BOP). Fasting blood sugar (FBS), insulin (FI), triglycerides (TG), and free testosterone along with serum and gingival crevicular fluid (GCF) levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were the biochemical parameters evaluated.
RESULTS: Women with PCOS had statistically significant differences in mGI, PI, testosterone, FBS, and TG when compared with healthy women (p oral cavity, in PCOS patients when compared with healthy individuals.
CLINICAL RELEVANCE: Women diagnosed with PCOS may have probabaility of co-existing gingival inflammation. Therefore, emphasis on medical treatment for PCOS and periodic screening for periodontal disease may be warranted.
