    A tick in the ear is a very painful condition and removal is difficult because it grips firmly to the external auditory canal or tympanic membrane. Facial paralysis is a rarely reported localised neurological complication of an intra-aural tick infestation. The pathophysiology of localised paralysis is discussed, together with the safe way of handling patients with an intra-aural tick infestation.

    This study aims to determine the prevalence of denture wearing among elderly and to compare the oral health related quality of life (OHRQoL) between elderly with dentures and those without dentures. This cross sectional study involved 506 randomly selected edentulous elderly in the district of Badang, Kota Bharu, Kelantan. Consented participants were interviewed in the Kelantanese dialect at their homes by a single trained interviewer using the short version Oral Health Impact Profile [S-OHIP(M)] which had been translated into the Malay language, tested and validated for use in Malaysian population. Denture wearing and self rated denture status was noted. The prevalence of denture wearing was 46.2% (95% CI=41.83, 50.70). There was a significant difference in sex, smoking status, self perceived treatment need and self perceived satisfaction between denture wearers and non denture wearers. Denture wearers reported better overall OHRQoL compared to non denture wearers (p

    Oral candidiasis is an opportunistic infection of the oral cavity. This study aimed to determine prevalence of oral candidiasis in patients with palatal coverage orthodontic appliances and prostheses and its risk factors. Three groups of patients were recruited after an informed consent. The two tested groups were the denture and the upper removable orthodontic appliance (URA) groups while patients with no prosthesis/appliance acted as control. The assessments included demographic profile, denture/URA age, night-time wearing and duration of wearing. Signs and symptoms of candidiasis were examined intra-orally. Unstimulated salivary flow rate test was also performed. Smears samples were taken from palatal mucosa and impression surfaces of denture/URA and stained with Periodic Acid Schiff (PAS). The data were analysed using descriptive and chi-square tests. A total of 86 patients were recruited; denture (n=30), URA (n=22), control (n=34). Denture and URA groups had significantly more positive cases of candidal infection (56.7 and 72.7% respectively) as compared to control group (20.6%). Among the subjects with oral candidiasis, denture patients were detected to have more severe amount of candidal hyphae (20%) than URA (13.6%) group. The relationships between oral candidiasis and these risk factors i.e. age, night-time wearing, daily total hours of wearing and denture/URA hygiene were statistically significant (p

    Resin-bonded fibre-reinforced composite bridges provide many advantages over the conventional
    bridges or implant treatment in the management of a traumatically or congenitally missing anterior tooth.
    Furthermore, there is an increasing demand towards providing a metal free resin-bonded bridges over the alloybased
    restorations in order to meet the aesthetic needs especially in the anterior region. Advances in the
    adhesive technology and tooth colored materials offer improved bonding system and better aesthetic outcome.
    Nevertheless, careful selection of cases to receive this type of approach is also one of the key factor to ensure
    the clinical survival of fibre-reinforced composite bridges. This report aims to present the use of fibre-reinforced
    composite to construct indirect cantilever fibre-reinforced composite bridges as part of minimum intervention
    dentistry.

    The purpose of this study was to evaluate the periodontal status distal to the adjacent second molar following the extraction of a partially or fully impacted mandibular third molar at Klinik Pergigian Pakar Hospital Universiti Sains Malaysia (KPPHUSM) from April of 2008 until June of 2008.This was a prospective study which involved the clinical and radiological study of patients. In this study, convenience sampling method had been used. The sample size was 22 patients aged 18-32 years old with inclusion criteria. The outcomes measured in this study were periodontal pocket depth (PPD), clinical attachment level (CAL) and alveolar bone height (ABH). Subjects were examined at distal surface (disto-buccal, mid-distal and disto-lingual) of second molar for PPD and CAL before and 3 months after the impacted adjacent lower third molar extraction. OPG was taken each before and after the third molar removal. These data were analyzed using SPSS version 16 and Wilcoxon-signed-ranks test was used to compare the PPD, CAL and ABH pre and post operatively. All the results were not significant with p >0.05. For PPD, median = 3mm pre and post extraction. CAL median= 2mm pre and post operatively and ABH median of 3.10mm (before) and 2.8mm (after) the third molar removal. From our study, we concluded that there were no significant changes of PPD, CAL and ABH at distal side of second molar after 3 months of the adjacent impacted lower third molar removal.

    The study aimed to compare the scope and pattern of practice between general dental practitioners (GDPs), restorative dentistry specialists and endodontists. Self-administered postal questionnaires were distributed to 22 restorative dentistry specialists, 16 endodontists and a random sample of 566 GDPs. The pre-tested questionnaire inquired about demographic data, endodontic practices and referrals. Fisher’s exact test with Bonferroni adjustment was performed for pairwise comparisons. The overall response rate was 73.8%. The restorative dentistry specialists and the endodontists performed a wider array of endodontic procedures than the GDPs and were more consistent in the use of specific armamentarium (p

    Sociodemographic factors have received considerable attention in the literature with regards its relationship with caries. However, the related information among children ages 12-17 is fairly limited. Birth order has been consistently found to be associated with diseases hypothesized to have an infectious aetiology but only few studies have examined its relationship with dental caries. The aims of this study were to determine the association of birth order and the sociodemographic background of subjects with caries and high caries experience among 16-year-old schoolchildren in Tumpat district, Kelantan. This was a case-control study. A total of 1087 16-year-old schoolchildren were examined intraorally for their caries status. They were categorized into three groups namely caries free (DMFS=0) mild caries (DMFS= 1-7) and high caries (DMFS ≥8) group based on DMFS score. Cases were the caries group and the controls were the caries free group. In each group, 163 subjects were selected by using simple random sampling. A questionnaire was used to obtain personal information of the subjects, birthweight and sociodemographic background. Analysis involved was ordinal logistic regression. The factor that was found to have association with caries and high caries experience determined using multiple ordinal logistic regression analysis was educational level of parents (OR=1.55, 95% CI: 1.06; 2.28). This study showed that birth order was not a significant factor associated with caries experience. Among the sociodemographic factors, only parent’s educational level was found to be associated with caries and high caries experience.

    Hamartomatous polyps of the tonsil are very rare. They have been described using various terms such as a lymphangiomatous polyp, lymphangiectatic fibrous polyp, lipomatous polyp or pedunculated tonsil, thus the actual incidence is difficult to be quantified. We present a case of hamartomatous polyp of the palatine tonsil in a 30-year-old female presented with recurent tonsillitis. Histopathological examination of the resected tonsils showed features of chronic tonsilitis with incidental finding of hamartomatous polyp characterized by a polypoidal tissue covered by stratified squamous epithelium and composed of thin-walled blood vessels, lymphatic channels, fibrofatty tissues, seromucinous glands and striated muscle fibres. An unusual incidental histopathological finding of a rare condition has been discussed along with the review of literature.

    The present study aimed to determine the best polymerase chain reaction (PCR) conditions for
    amplification of odontoblast markers; alkaline phosphatase (ALP), dentin matrix protein 1 (DMP1), dentin
    sialophosphoprotein (DSPP) and osteopontin (OPN). Informed consent was obtained from the individuals
    prior to tooth extraction. RNA was extracted from odontoblasts obtained from extracted teeth using
    innuPREP RNA Mini kit (Analytik Jena, Germany). Five selected target factors in enhancing PCR: primer
    concentration, extension time, number of cycles, annealing time, and annealing temperature were
    manipulated to yield the correct size of amplicons. One step reverse transcriptase PCR reactions were
    performed using MyTaq One-Step RT-PCR kit (Bioline, USA) with a C1000 Thermal Cycler (Bio-Rad, USA)
    in a 25 µL reaction, keeping the amount of 2 ng/µL RNA, 0.25 µL reverse transcriptase, 0.5 µL RiboSafe
    Rnase inhibitor and 1X MyTaq One-Step Mix, constant. The optimal conditions were determined to be
    400nM of primers for DMP1 and DSPP, 200 nM for ALP and OPN; 30 seconds of extension time and 35
    PCR cycles for all genes; 10 seconds of annealing time for ALP, DMP1 and DSPP, 7 seconds for OPN. The
    annealing temperature were 56.4°C for ALP, 58.6°C for DMP1, 52.7°C for DSPP, and 56.3°C for OPN,
    respectively. The optimized PCR protocols produced the correct size of odontoblast markers.

    The unilateral nasal symptom should trigger a treating physician to a certain diagnosis. The differential
    diagnosis includes foreign body, rhinolith and tumour. The chronicity of symptom helps a lot with the diagnosis.
    Foreign body for example, tends to present with positive history of insertion, mainly by children or the acute
    symptom of local infection. In the presence of prolonged symptom, rhinolith should be suspected especially when
    the patient presents with pathognomonic nasal obstruction with foul smelly discharge. A referral should be made
    for a nasoendoscopy evaluation whenever a rhinitis-like symptoms remain after a period of medical treatment for
    allergy. We share a case of a missed diagnosis of a rhinolith after six years of symptoms.

    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.

    Human salivary exosomes have been identified as a highly informative nanovesicle with clinical-relevant information for variation of diagnostic purposes. As a continued effort from previous studies on human salivary exosomes effect at gene expression level, this study is carried out to observe the morphology of human periodontal fibroblast (HPdLF) treated with exosomes cells under the same period of changes in genotypic level occurred. In vitro, HPdLF cells were cultured for 24 hours with 10 μg/ml of human salivary exosomes. The morphology of HPdLF cells was examined under inverted light microscopy and scanning electron microscopy (SEM) for both control samples and samples treated with human salivary exosomes, while the cell count was performed via trypan blue staining. There was no significant difference in the morphology under the inverted light microscopy and the cell number of HPdLF cells for both treated and untreated cells with exosomes. However, for SEM, the treated HPdLF with salivary exosomes showed slight observable changes on the filopodia, lamellipodia, cytoplasmic vesicles and the cytoskeleton of the cells. Even within a short period (24 hours) of culturing time for cells with human salivary exosomes, the samples showed minimal changes which positively suggested a simultaneous event of exchanging materials from human salivary exosomes to cells had occurred, hence, potentially proving that human salivary exosomes can enhance cell proliferation.

    Use of synthetic hydroxyapatite (HA) in biomedical applications is well warranted. It has shown to have an excellent biocompatibility in human tooth and bones. Additionally it has been documented to possess antibacterial potentials. The present study was conducted to assess the presence of any such potential in locally produced (HA) using Streptococcus mutans, a common pathogen in the oral cavity. The study was carried out using 50, 100, 150, 200, 300, 400 and 800 mg/ml concentration of HA. The antibacterial property of HA was assessed using Miles and Misra method. Our studies showed that bacterial growth inhibitions of S. mutans occurred from 50 mg/ml, and complete inhibition was perceived at concentrations at 200mg/ml of HA. The antibacterial property HA should be used to good advantage as a bioactive biomaterial in dental and maxillofacial applications.

    This in-vitro study aimed to evaluate and compare the marginal leakage and penetration ability of
    a moisture-tolerant (Embrace WetBondTM) and a conventional (ClinproTM) resin-based sealants under three
    different enamel surface preparations (acid etched, acid etched and saliva contaminated and bur
    preparation and acid etched). One hundred and twenty extracted caries free human premolars teeth were
    cleaned and randomly divided into six groups of equal numbers, according to the type of sealants used and
    surface preparations. All the sealed teeth were subjected to thermocycling and immersed in a methylene
    blue dye. Each tooth was then embedded into acrylic resin before it was sectioned into four sections per
    tooth. Marginal leakage and unfilled surface area (indicating penetration depth of resin) were then
    measured using an optical 3D measurement device (Alicona Infinite Focus®). Both sealants exhibited
    comparable proportion of marginal leakage on acid etched only surfaces. Moisture-tolerant sealant showed
    the least proportion of marginal leakage on bur prepared and etched surfaces. Presence of saliva has
    detrimental effect on adhesion of both sealants. Nevertheless, depth of penetration of sealant into the
    fissures is comparable with both sealant types irrespective of the surface preparations.

    Glass ionomer cement (GIC) has theunique fluoride release property and able to formionic bond with tooth structure. However, the brittleness of the material results in low hardness. In the present study, a new approach in utilization of local waste materials as fillers for improvement of hardness of GIC is reported.The synthesized wollastonite and mine-silica by-product were individually incorporated into commercial GIC and the Vickers hardness were evaluated. The results shown that the incorporation of 1 % wollastonite into GIC gave ~ 6% increment in hardness compared to the control GIC (66.53H ±7.37 versus 62.66HV±2.98)but not for themine-silica. Thus, wollastonite could be a potential material to be utilized as fillersin dental restorative composite

    Cephalometric analyses using computer software have more advantages than manual analyses. However, the software should be evaluated for the accuracy and reproducibility before it can be used. The aims of the present study were: 1) to compare the differences in accuracy and precision between utilizing scanned images and soft copy images with the software 2) to assess the reproducibility of software and manual cephalometric analyses. Fifteen cephalograms were selected randomly from the Record Unit, Hospital Universiti Sains Malaysia. All films had 10 fiducial points marked and were scanned at 75 dots per inch (dpi) and 300 dpi. Manual and digital measurements were compared to obtain magnification factors. Seven digital x-ray images of a caliper were taken. The mean differences were measured between the fixed caliper measurement and digital measurements. Subsequently, 37 cephalograms were traced manually and digitally with Computer-Assisted Simulation System for Orthognathic Surgery (CASSOS) software to assess its accuracy and reproducibility after applying the obtained magnification factor. Steiner analysis was utilized and T tests were used to evaluate the mean difference. P

    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.

    Gingival overgrowth is frequently observed in patients taking certain drugs such as calcium channel blockers, anticonvulsants and immunosuppressant. This can have a significant effect on the quality of life as well as increasing the oral bacterial load by generating plaque retention sites. Amlodipine, a third generation calcium channel blockers has been shown to promote gingival overgrowth although in very limited cases reported. The management of gingival overgrowth seems to be directed at controlling gingival inflammation through a good oral hygiene regimen. However in severe cases, surgical excision is the most preferred method of treatment, followed by rigorous oral hygiene procedures. This case report describes the management of gingival overgrowth in a hypertensive patient taking amlodipine. Combination of surgical gingivectomy and CO2 laser treatment was used to remove the gingival overgrowth. CO2 laser surgery produced good hemostasis and less pain during the procedure and post operatively. This case report has also shown that periodontal treatment alone without a change in associated drug can yield satisfactory clinical response.
