    Linum usitatissimum commonly known as flaxseed is one of the oldest crops traditionally cultivated
    mainly for its oil purposes. Flaxseed is widely known for its rich source of nutritive and bioactive compounds. Recently, it has gained considerable interest due to the potential health benefits attributed to its component of metabolites, including its antimicrobial properties. Two main components of flaxseed, the unsaturated fatty acids and lignan, are suggested as the main metabolites that exhibit antimicrobial activities. This paper aims to give an overview on fatty acid and phenolic compound in flaxseed and their possible activities as antimicrobial agents.

    This study aimed to review the availability of sugar-free medicine available in the market using the online Monthly Index of Medical Specialties (MIMS) Malaysia 2016. Data collection was obtained from product information (PI) for prescription medications contained in the MIMS Malaysia 2016. Concise information for each product was collected based on therapeutic class groupings. The therapeutic class obtained from PI was assigned to one of the 11 major therapeutic classes. PI that stated its use in paediatrics was further reviewed for the availability of sugar free ingredient. Each product was then allocated into the poison groups: Group B, Group C and Non-Scheduled Poison. A total of 282 PI items from 336 companies in MIMS Malaysia 2016 that satisfied our eligibility criteria were reviewed. Of the 282 PI items reviewed, most of the products, 169 (59.9%) were sugarbased product, while 87 (30.9%) of them belong to sugar free products. Our study found that most of the medicines reviewed in the MIMS Malaysia 2016 were under Group C (134 of total 282). There is still a high number of sugar-containing medicines despite the promotion of sugar-free medication. Therefore, consumers need to be educated on the use of sugar-free medicines in children to increase the demand and availability in the market.

    Oral cancer remains as a worldwide health issue. In Malaysia, oral neoplasm contributed about 10.6% death at the government hospitals. The significant consequences of delaying referral and poor prognosis of oral cancer was mainly due to the lack of knowledge among public. This study aims to determine the level of awareness and knowledge on oral cancer among students with non-medical background in Kepala Batas, Pulau Pinang, Malaysia. A cross sectional study using questionnaires were conducted among systematically randomly selected 275 non-medical background students aged 18 years old and above. The association of smoking habit with oral cancer awareness and knowledge was evaluated using chi-square test. Factors associated with the knowledge were determined at both univariable and multivariable levels using simple logistic and multiple logistic regression analyses respectively. Oral cancer awareness level was high among the students (85%) even though knowledge on early signs of oral cancer was low (19 years old has 1.96 time the odds compared to students aged ≤19 to have poor knowledge while Malay has 4.28 time the odds compared to Indian to have poor knowledge. Although smoking was observed as the most recognisable risk factor of oral cancer (82%), the smoking prevalence was relatively high (46.9%). The smokers in this study had low awareness and knowledge on oral cancer compared to the non-smoker. Hence, preventive measures adopting knowledge transfer should be proposed to enhance individual awareness and knowledge on oral cancer with Smoking cessation programme to help the smoker to quit smoking

    Clinacanthus nutans (C. nutans), a well-known ethnopharmacological plant consumed for its medicinal purposes by Southeast Asian communities. C. nutans is said to possess antipyretic, inflammatory, antiedemic as well as analgesic properties and used traditionally in treating various skin ailments, Herpes infection, cancer and diabetes. The young leaves of this C. nutans are consumed in Malaysia for maintaining health. In this study, the proliferative activity of human gingival fibroblast cells (HGF-1, ATCC®CRL-2014™, USA) treated with the ethanol extract obtained from C. nutans leaves at three different concentrations (250, 125 and 62.5 µg/ml) was compared with the untreated cells using alamarBlue assay. The proliferative activity of HGF-1 using alamarBlue assay showed that the cells treated with 62.5 μg/ml of ethanolic extract of C. nutans leaves exhibited increased proliferation compared to the other groups and hence does not exhibit any cytotoxicity on HGF-1.

    Dental caries and gingivitis are common oral health problems affecting schoolchildren worldwide. Effective tooth brushing in children is fundamental in preventing dental caries and gingivitis and maintaining good oral health. Children routinely present with unsatisfactory oral hygiene due to poor compliance and poor dexterity in tooth brushing. The purpose of the present study was to evaluate the effectiveness of a novel T-shaped toothbrush in plaque removal and gingival health among children and to obtain feedback regarding its use. Nineteen participants aged 8-10 years who fulfilled the criteria enrolled in this study. The children were taught the proper technique of using the new toothbrush and instructed to use it for a period of 2 weeks. The plaque scores and gingival scores were measured at baseline and after 2 weeks. They were asked to complete a questionnaire regarding the use of the toothbrush after 2 weeks. Statistical analysis was performed using t-test. There was a statistically significant (p

    One of the roles expected of dental personnel is to promote dental seeking behaviour to the public. It is to ensure that adults maintain an optimum number of teeth for overall health and quality of life by enabling them to eat, speak and socialise without pain, discomfort or embarrassment. The objective of this study was to determine the reasons for seeking dental care and the factors that influence this decision among adult patients. This was a retrospective study of clinical records among patients of 18 years old and above who attended Universiti Sains Islam Malaysia (USIM) Dental Polyclinic, an academic dental centre, for the first time from January 2015 to December 2016. Socio-demographic data on age, gender and occupation as well as the reason for the visit were retrieved from the clinical records. Analysis of data was conducted using SPSS software version 21.0 and the pvalue was set at p

    Polymorphism in PAX9 (rs8004560), a gene responsible for craniofacial and tooth development, is often associated with Class II/Div2 malocclusion. This study aimed to detect the presence of PAX9 SNP (rs8004560) and to determine its genotype and allele distribution in Class II skeletal base malocclusion, contributed by retrognathic mandible, in the local Malaysian population. The association of PAX9 SNP (rs8004560) with Class II skeletal base malocclusion was also determined. A case control study was performed on 30 samples; 15 from Class II skeletal base malocclusion, and 15 from Class I skeletal base subject as control. Cephalometric measurements were performed prior to saliva samples collection. Genomic DNA was extracted from unstimulated saliva of all subjects, and the DNA was amplified using specific primers for marker rs8004560, followed by genotyping by sequencing. SHEsis online software was used to analyse Hardy-Weinberg Equilibrium (HWE) for cases and controls. Allelic and genotypic frequencies were compared between cases and controls. Significant difference in allele frequency was observed within the group whereby G allele was over-represented in the analysed population (p0.05). Although no genetic association between PAX9 SNP (rs8004560) with Class II skeletal base malocclusion was observed, significant difference in allele frequency observed might provide some indication in the involvement of PAX9 polymorphism in Class II skeletal base malocclusion contributed by retrognathic mandible. Further research utilising larger sample size will be required in order to determine the role of PAX9 gene in the aetiology of Class II skeletal base malocclusion observed in the local Malaysian population.

    Renal cancer is a rare occurrence in all adult malignancies, and renal cell carcinoma (RCC) is the most common type. Due to its aggressive behaviour and high tendency for metastasis, manifestation of RCC varies, often with non-urologic features or symptoms from metastatic sites. Metastatic RCC to the head and neck region is rare particularly to the tongue are extremely rare. We report an elderly lady who presented with recurrent tongue mass metastasis from RCC, a rare cancer with even rarer metastatic site.

    Primary thyroid lymphoma is a relatively uncommon pathology of the thyroid gland that mainly occurs in elderly females. We describe a rare case of B-cell thyroid lymphoma in a young healthy male. It is an important diagnosis to be considered in patients presenting with a rapidly enlarging neck mass as its management is different from other differentiated thyroid carcinoma which require total thyroidectomy plus adjuvant radioactive iodine ablation. Our report emphasizes the need for clinical awareness leading to early detection, followed by early multidisciplinary management.

    A survey was conducted to assess dental caries experience and oral health related behaviour among Malaysian Territorial Army (TA) personnel. This cross-sectional study involved 284 personnel covering their socio-demography, oral hygiene habits and related behaviour and past utilization of dental services pattern. Dental caries were assessed using DMFT index. Caries prevalence was very high (97.2%; DMFT 8.15±5.36). Untreated decay (DT) was 3.67 (±3.15) and missing teeth (MT) 2.90 (±3.73). However, few were treated teeth (FT) at only 1.58 (±2.02). Almost everyone (98.2%) claimed they brushed their teeth at least once daily and 80% used fluoridated toothpaste. However, very few participants used dental floss (11.3%) while majority (60.2%) did not know about flossing. More than 70% were current smokers. Only 13.7% were regular attendees with the majority (86.3%) visiting the dentist only when they had dental problems. The most common reason (49.7%) for their last dental visit was related to presence of symptoms and few were (27.4%) for prevention. Symptomatic attendees are significantly more likely to have more severe caries experience than preventive oriented individuals (p=0.003). These findings support the importance of promoting preventive oral health utilization behaviour among army personnel.

    Some restorative materials are susceptible to erosion but whether it also causes microleakage is still questionable. The aim of this study was to assess the microleakage of few restorative materials after immersion in acidic solution. Standardized ‘U’ shaped cavity of 4mm diameter and 2mm depth were prepared on buccal or lingual surface of 52 human premolar and molar teeth. The teeth were divided into 4 groups which contains 13 samples and 3 controls for each and were restored either with Filtek Z250 (Group 1), Fuji IX (Group 2), Fuji II LC (Group 3), or Silverfill amalgam (Group 4).
    All surfaces were painted with nail varnish leaving only 2mm of tooth structure surrounding the restoration before the study samples were immersed in acidic solution, lemon juice (pH 2.74) and control samples in deionised distilled water for 24 hours. Surface photos for erosion were taken before immersion in methylene blue for 7 days. After sectioning, the assessment of dye penetration was done using Leica Imaging System DMLM (Germany). Photos showed that Fuji IX demonstrated severe erosion but no obvious changes were seen on other materials. Kruskal-Wallis test indicated that microleakage between all four groups were statistically significant. The most significant difference was between Filtek Z250 and Fuji IX (p

    This is a cross-sectional study in a representative sample of preschool children from 12 preschools (TADIKA KEMAS) Pasir Mas, Kelantan, Malaysia. Data on socioeconomic status and sources of water supply at home were collected through interview with mothers. Children’s anthropometric data (height and weight) and body-mass-index-for-age (BMI-for-age) was calculated. Oral examinations of ECC status was based on the dmft index (WHO, 1997). The results showed mean
    carious teeth were very high (dmft 11.1±4.8) and almost every preschool child was affected with ECC (prevalence 98.1%). The majority were in “high caries” category (i.e. dmft >7) and about 51.4% of preschoolers was underweight and only a few was overweight/obese. Preschool children with high caries mostly were underweight and normal of BMI. The BMI-for-age, household income and household expenditure for food were significant correlation with ECC experience (p

    Dentistry has searched for an ideal material to place in osseous defects for many years. Endogenous bone replacement has been the golden standard but involves additional surgery and may be available in limited quantities. Also, the exogenous bone replacement poses a risk of viral or bacterial transmission and the human body may even reject them. Therefore, before new biomaterials are approved for medical use, mutagenesis systems to exclude cytotoxic, mutagenic or carcinogenic properties are applied worldwide. The present preliminary study was carried out in five male New Zealand white rabbits (Oryctolagus cuniculus). Porous form of synthetic hydroxyapatite granules (500 mg), manufactured by School of Materials and Mineral Resources Engineering, Universiti Sains Malaysia, Penang, was implanted in the femur of the rabbits. Blood samples were collected prior to implantation and one week after implantation. The blood was cultured in vitro and the cell division was arrested at metaphase using colcemid. This was followed by the hypotonic treatment and fixation. Then, the chromosomes were prepared and stained for analysis. The modal chromosome number of rabbit (Oryctolagus cuniculus) was found to be 2n=44. The mean mitotic index values prior to and after implantation were 3.30 ± 0.66 and 3.24 ± 0.27 per cent respectively. No gross chromosome aberrations, both numerical and structural were noticed either prior to or after implantation of the biomaterial. These findings indicate that the test substance, synthetic hydroxyapatite granules does not produce gross chromosome aberrations under the present test conditions in rabbits.

    Tooth wear is the non-carious loss of tooth tissue due to attrition, erosion and/or abrasion. The amount of wear that accelerates physiological tooth wear is referred as pathological tooth wear. This study aims to determine the prevalence and mean scores according to mouth quadrant of raw tooth wear (RTW) and pathological tooth wear (PTW) and investigate sex association with PTW among 16-year-old secondary school children in Kota Bharu, Kelantan. This cross-sectional study involves 688 participants randomly selected from eight government secondary schools. The Smith and Knight Tooth Wear Index (TWI) was used. Data were analyzed using a simplified Microsoft Excel program developed based on the index to quantify PTW. Bar graphs were plotted to highlight the mean scores according to mouth quadrant. About 44% of participants were male and 56% were female. The prevalence of RTW and PTW among subjects was 100% and 20.1% respectively. It was found that 32.8% of tooth surfaces were affected with RTW and 0.7% of study subjects already had exposed dentine. The most affected quadrant for RTW and PTW was the upper and lower incisal quadrant respectively. Males had 92% more odds of developing tooth wear compared to females. In conclusion, all subjects have some degree of wear. About one-fifth of the study subjects were affected by PTW. The patterns of wear were similar to those encountered in the Western societies. There was statistically significant association between sex and PTW.

    We present an algorithm to reduce the number of slices from 2D contour cross sections. The main aim of the algorithm is to filter less significant slices while preserving an acceptable level of output quality and keeping the computational cost to reconstruct surface(s) at a minimal level. This research is motivated mainly by two factors; first 2D cross sections data is often huge in size and high in precisions – the computational cost to reconstruct surface(s) from them is closely related to the size and complexity of this data. Second, we can trades visual fidelity with speed of computations if we can remove visually insignificant data from the original dataset which may contains redundant information. In our algorithm we use the number of contour points on a pair of slices to calculate the distance between them. Selection to retain/reject a slice is based on the value of distance compared against a threshold value. Optimal threshold value is derived to produce set of slices that collectively represent the feature of the dataset. We tested our algorithm over six different set of data, varying in complexities and sizes. The results show slice reduction rate depends on the complexity of the dataset, where highest reduction percentage is achieved for objects with lots of constant local variations. Our derived optimal thresholds seem to be able to produce the right set of slices with the potential of creating surface(s) that traded off the accuracy and speed requirements.

    The objective of this study was to evaluate and compare the effect of times elapsed on the application of a single-step adhesive system and activation of light cured subsequently placed composite to the bond strength between composites and adhesives. This was an experimental study using fifteen teeth extracted human premolars, which were caries and pathology free. Sample of teeth were embedded up to cemento-enamel junction on box of acrylic resin. All teeth were cut to obtain flat occlusal dentin surfaces. The specimens were randomly selected and divided into three groups with five teeth each. All the teeth were assigned to single-step bonding system AQ Bond (Sun Medical Co. Ltd., Shiga, Japan) according to manufacturer’s direction. Group 1 was left for 45 seconds, group 2 for 2 minutes, while group 3 was 5 minutes before putting subsequently restorative material. Composite resin was applied in 3 mm diameter and 6 mm height of cylinder mold and cured according to manufacturer’s direction on the dentin surface. Shear bond strength were measured using a testing system (Instron 8874, Instron Corp., Canton, MA, USA) at a crosshead speed of 2 mm/min with cell load capacity of 25 KN. The bond-strengths between single step adhesive system (AQ Bond) and light cured composites were tested. Mann-Whitney test showed no significant differences in bond-strength between Group 1 and Group 2. However, there were significantly differences (p

    Several studies on job stress have been conducted among nurses, teachers, clerks, lecturers, laboratory technicians, petroleum and automotive workers and the calculated prevalences ranged from 20-35%; associated factors identified include high job demand, low job control and poor social support. Thus, the aim of the present study was to determine the prevalence and associated factors of stress in dental healthcare workers of an institution of higher learning in Kelantan. A cross-sectional study of the prevalence and associated factors of stress in 54 dental healthcare workers of an institution of higher learning in Kelantan [response rate of 63.5 percent] was conducted in March 2006. The Malay version of the validated Depression, Anxiety and Stress Scale and Karasek’s Job Content Questionnaire were used as research instruments in this study. Informed consents were obtained from all participants. The prevalence of stress was 22.2%. One (1.9%) staff member experienced severe stress whilst 20.4% experienced mild to moderate stress. After controlling for age, sex, marital status and duration of work, psychological job demand (adj. b 0.61, 95% CI 0.21, 1.00, p=0.003), toxic exposures (adj. b 1.41, 95% CI 0.47, 2.35, p=0.004) and overtime work (adj. b 5.67, 95% CI - 1.18, 10.16, p=0.015) were directly associated with reported stress in dental healthcare workers. High psychological job demand, increased toxic exposures at work and increased overtime work were significantly associated with stress in dental healthcare workers. These findings can be used to guide preventive measures to reduce stress in dental healthcare settings.

    Pyogenic granuloma is a benign lesion which is commonly found in the oral cavity. It is a reactive inflammatory process of the injured mucosa to trauma. It can appear as a sessile or pedunculated mass with smooth or lobulated surface, which sometimes can mimic malignant lesion. Excision biopsy of the lesion is the confirmatory investigation which also a treatment tool. We report a case of middle-aged lady who had pyogenic granuloma of the tongue, which was safely excised using ultrasonic scissors. This case highlights the new technique of using ultrasonic instruments for excision of benign tongue lesion, with marked reduction of blood loss and operation time.

    Abstract Water quality in the dental unit waterlines (DUWLs) is important to the patients and dental health care personnel as they are at risk of being infected with opportunistic pathogens such as Pseudomonas or Legionella species. In this study, a total of 86 samples were collected from DUWLs of 19 dental units in 11 Malaysian Armed Forces dental centres (MAFDC). 350 ml water sample was collected in sterile thiosulphite bags from the outlets of 3–way syringe, high speed handpiece, scaler, cup filler, independent water reservoir or the tap of the same surgery respectively. Samples were transported to the laboratory within 24 hours and kept in the refrigerator at 40C. 100ml of each sample was filtered through a 0.45 μm polycarbonate membrane filter. The filter was then inoculated onto plate count agar and incubated at 370 C for 24 hours, after which the formed colonies were enumerated. Another separate 100ml of water sample was poured onto buffered charcoal yeast extract agar and cetrimide agar to culture Legionnella and Pseudomonas respectively. Identification of these bacteria were confirmed by polymerase chain reaction and sequencing. Pseudomonas aeruginosa was detected in 9.5% of the samples but Legionnella was not detected in any of the samples. 77% of the samples met American Dental Association (ADA) recommendation of less than 200 cfu/ml. The result of this study showed that it is difficult if not impossible to eliminate biofilm from the DUWLs. Regular monitor of water quality from DUWL is required to maximise the health of the dental patients and dental health care personnel.

    The objective of this study was to evaluate the effects of salivary testing in dental caries assessment. The role of saliva flow rate, pH, viscosity and buffering capacity in subjects with high caries (DMFT>5) (group 1) against subjects with low caries (DMFT=0) (control group) were evaluated. 40 subjects between the age of 18 and 40 years old were selected (20 subjects control group and 20 subjects group 1). By using a salivary testing kit (GC Asia Dental Pte Ltd, Japan), each subject underwent test such as hydration status of the oral mucosa, viscosity and pH of resting saliva, stimulated salivary flow rate and buffering capacity of stimulated saliva. The results showed that the flow rate, viscosity, pH and buffering capacity of saliva in subjects of group 1 (DMFT>5) was significantly lower (p
