    To assess their awareness and usage of mouthguard and occurrence of sports-related oral injuries in athletes who involve in various sports activities in Kota Bharu. A cross-sectional study was carried out among 180 athletes aged 12 to 27 years. A structured interviewer-guided questionnaire was used to determine the prevalence of oral injuries sustained during sport activities, the use of mouthguard as well as the athletes' awareness of mouthguard use. The respondents consisted of 107 males (59.5%) and 73 females (40.5%) with a mean age of 16.7 years (SD 5.53). There were 60 (22.2%) athletes who had one or more types of sports-related oral injuries sustained. Laceration of lips, tongue and gums were the most frequent injuries (57.5%) while loosening of teeth and fracture of teeth sustained in 12.5% and 10.0% of athletes respectively. Malay traditional martial arts silat athletes, 17(68.0%) experienced the highest oral injuries among athletes. The prevalence of oral injuries was significantly different between ball sports, martial arts and other non-contact sports (p=0.002). Sixty-one athletes (33.9%) reported that they were aware of mouthguard; however none of the athletes used the mouthguards during their sports activities. Malay traditional martial arts silat was the most common susceptible to sustain oral injuries. None of the athletes were wearing mouthguard. Education on prevention of orofacial trauma should be given to the coaches and athletes. Wearing of mouthguard during sport activities should be compulsory during practice and competition events.

    The oral health awareness and status among the Universiti Kebangsaan Malaysia first year dental students were studied. Seventy-three subjects underwent two components of assessment: questionnaire assessing oral health awareness and behaviour, and clinical examination of oral health status. Indices used including Plaque, Calculus, Community Periodontal Index for Treatment Needs (CPITN) and total score of Decayed, Missing, Filled and teeth indicated for Extraction (DMFX[T]). More than 90% of the subjects were reported to brush their teeth twice or more daily and used supplemental cleaning tools. They also knew the importance of healthy oral condition, the various causes and prevention of tooth decay and gum diseases. Although 70.3% felt they need dental treatment, the majority (81.9%) visited the dentist only when they feel it is necessary to do so. Clinical examination showed low scores of 0.99 and 0.40 for mean plaque and calculus indices, respectively, while 80.8% of the subjects have mild calculus accumulation. Code 2 of the CPITN Index was the highest (70.3%) among the subjects. The total DMFX was 291, with mean score of 0.14 per subject and the decayed component was the highest (D=186 teeth). These findings suggest that the subjects have acceptable oral health awareness, and also good existing oral health status.

    Scurvy resulting from dietary deficiency of vitamin C is characterized by anaemia, tender limbs swelling and hemorrhagic manifestations such as petechiae and bruises. We report a case of scurvy in a 13 years old boy with cerebral palsy who presented with history of limbs bruising and swelling for 2 months. On examination, he was cachexic and pale with poor dentition and swollen gum. There were extensive bruises and swollen limbs as well. His platelet count and coagulation profile were normal. Limbs X-ray revealed classical scorbutic changes in the long bones. Serum ascorbic acid level was low

  4. Fulltext Rheological studies on the effect of different thickeners in texture-modified chicken rendang for individuals with dysphagia
    Abu Zarim N, Zainul Abidin S, Ariffin F
    J Food Sci Technol, 2018 Nov;55(11):4522-4529.
    PMID: 30333649 DOI: 10.1007/s13197-018-3386-5
    Texture-modified food has become an important strategy in managing dysphagia. Pureed food is proven to be the safest texture due to its high viscosity which can slow down the rate of the food bolus during swallowing. In this study, texture-modified chicken rendang was developed according to Texture C (smooth puree) as described by the Australian standard for texture-modified food. Samples were added with five different thickeners (sago starch, tapioca starch, modified corn starch, xanthan gum and carboxymethyl cellulose gum) at three different concentrations (10, 20 and 30% w/w). Their rheological effects were analyzed through dynamic and steady shear test. Results obtained reveals that samples contained xanthan gum have higher structure rigidity and shear thinning behaviour, while carboxymethyl cellulose gum provides the highest viscosity as well as yield stress than other samples. In terms of concentration, a strong dependence of structural rigidity and viscosity of all prepared samples with amount of thickeners added was observed. Overall, based on its rheological properties, the addition of carboxymethyl cellulose gum at 30% concentration was found to be the most suitable thickener, to be incorporated in the texture-modified chicken rendang. Selecting a suitable food thickener in developing food for individual with dysphagia plays an important role to ensure the right texture and consistency for their safe consumption.

  6. Fulltext Non-Surgical Retreatment After Failed Intentional Replantation: A Case Report
    Ong TK
    Eur Endod J, 2019;4(3):145-149.
    PMID: 32161902 DOI: 10.14744/eej.2019.03016
    A 27-year-old male patient complained of dental pain on previously root-treated tooth #17. Intentional replantation (IR) was performed. However, the symptoms returned at 10 months of follow-up, and a sinus tract was detected on the buccal gingiva of tooth #17. The patient refused extraction of the tooth and tooth was scheduled for non-surgical retreatment. Root canal retreatment was initiated with the removal of the previous root filling material while leaving the retrograde filling in situ. After 1 month of intracanal medication, the tooth became asymptomatic with complete healing of the sinus tract and the root canal filling was completed. Clinical and radiographic examination at 1 year follow-up revealed endodontic success with complete resolution of periapical radiolucency. This case report shows that non-surgical retreatment could be a viable alternative for failed IR.

    Poor oral health has been associated with several chronic and systemic disease. Currently, the most common method of teeth cleaning is the use of a toothbrush together with dentifrices. However, natural chewing stick such as S. persica miswak is still used in many developing countries due to their low cost and availability. The present review aims to summarize the evidences on effectiveness of miswak in promoting oral health. The search was performed using Medline via Ebscohost, Scopus and Google Scholar database to obtain relevant articles published between 2010 to May 2020 using the following set of keywords 1) Miswak OR Salvadora OR persica AND 2) dental OR caries OR plaque OR oral OR orthodontics. Isolated microbial inhibition studies were excluded from the review due to its well-established wealth of literature. Miswak was administered as ten different forms, namely mouthwash, toothpaste, chewing stick, essential oil, aqueous extract, ethanol extract, probiotic spray, dental varnish, dental cement or chewing gum. All studies reported a positive effect of miswak as an anti-plaque, anti-gingivitis, anti-cariogenic, promotion of gingival wound healing, whitening properties, orthodontic chain preservation, and biocompatibility with oral cells. Miswak in its different forms demonstrated positive effect towards oral health maintenance and management.

    Sains Malaysiana, 2014;43:1157-1163.
    Diabetes is an important risk factor in the pathogenesis of periodontal disease. Subjects with diabetes have a greater prevalence and severity of periodontal disease compared with subjects without diabetes. This study was carried out to assess periodontal status, treatment needs and oral health awareness among a selected population of Malaysian Type 2 diabetics. Ninety four Type 2 diabetes subjects were divided into those diagnosed with periodontal disease (PD+) (cPrrAr.3) and healthy/ gingivitis (PD-) (cPrrAr2) groups based on the Community Periodontal Index of Treatment Needs (CPITN). Subjects were interviewed regarding socio-demographic data and oral health awareness. Their medical information was obtained from the medical records. The results showed that 55.3% subjects had (PD+) as compared with 44.7% (PD-) subjects. 18.1% subjects required advanced periodontal treatment with specialist referrals. Male diabetic subjects were more likely to have advanced periodontal disease compared to female subjects (p<0.05). Subjects with advanced periodontal disease were more likely to be on combination of insulin and oral drugs (p<0.05). (PD+) diabetic subjects were aware that they had mobile teeth (p<0.001) and gum disease (p=0.004). In conclusion, male diabetics in Malaysia and subjects on combination of insulin and oral diabetic drugs are more likely to require advanced periodontal treatment.

    PMID: 33724901 DOI: 10.1080/15321819.2021.1895216
    This study reports the influence of peste des petits ruminants (PPR) vaccination on the clinico-pathological outcomes of PPR in the face of an outbreak. Twenty-two West African dwarf goats procured for a different study started showing early signs of PPR during acclimatization. In response, PPR vaccine was administered either intranasally with phytogenic mucoadhesive gum (Group A; n = 6) or without gum (Group B; n = 6); subcutaneously (Group C; n = 6) or not vaccinated (Group D; n = 4) and studied for 21 days. The clinical scores, hematology, serology and pathology scores were evaluated. Clinical signs of PPR were present in all groups, presenting a percentage mortality of 33%; 33%; 64% and 100% for Groups A, B, C, and D, respectively. Polycythemia and mild leukopenia were observed in all groups, and all animals were seropositive by day 7 post-vaccination. The lung consolidation scores were low in Groups A and B, compared to Group C. Histopathological lesions consistent with PPR was observed in the lymphoid organs, gastrointestinal tract, and lungs with the presence of PPR antigen as detected by immunohistochemistry. The findings suggest that intranasal vaccination with or without mucoadhesive gum may influence the outcome of PPR infection more than the subcutaneous route in the face of an outbreak.

    Daood U, Abduljabbar T, Al-Hamoudi N, Akram Z
    J Periodontal Res, 2018 Feb;53(1):123-130.
    PMID: 28940417 DOI: 10.1111/jre.12496
    BACKGROUND AND OBJECTIVE: The aim of the present study was to compare clinical periodontal parameters and to assess the release of C-telopeptides pyridinoline cross-links (ICTP) and C-terminal crosslinked telopeptide (CTX) from gingival collagen of naswar (NW) and non-naswar (control) dippers.

    MATERIAL AND METHODS: Eighty-seven individuals (42 individuals consuming NW and 45 controls) were included. Clinical (plaque index, bleeding on probing, probing depth and clinical attachment loss) and radiographic (marginal bone loss) periodontal parameters were compared among NW and control groups. Gingival specimens were taken from subjects in NW and control groups, assessed for ICTP and CTX levels (using ELISA) and analyzed using micro-Raman spectroscopy. The significance of differences in periodontal parameters between the groups was determined using Kruskal-Wallis and Mann-Whitney U tests. The percent loss of dry mass over exposure time and the rate of release of ICTP and CTX from all groups were compared using the paired t-test to examine the effects of exposure time.

    RESULTS: Clinical and radiographic periodontal parameters were significantly higher in the NW group than the control group (P

    Meka VS, Nali SR, Songa AS, Kolapalli VR
    AAPS PharmSciTech, 2012 Dec;13(4):1451-64.
    PMID: 23090110 DOI: 10.1208/s12249-012-9873-5
    The main objective of the present study is the physicochemical characterization of naturally available Terminalia catappa gum (Badam gum [BG]) as a novel pharmaceutical excipient and its suitability in the development of gastroretentive floating drug delivery systems (GRFDDS) to retard the drug for 12 h when the dosage form is exposed to gastrointestinal fluids in the gastric environment. As BG was being explored for the first time for its pharmaceutical application, physicochemical, microbiological, rheological, and stability studies were carried out on this gum. In the present investigation, the physicochemical properties, such as micromeritic, rheological, melting point, moisture content, pH, swelling index, water absorption, and volatile acidity, were evaluated. The gum was characterized by scanning electron microscopy, differential scanning calorimetry (DSC), powder X-ray diffraction studies (PXRD), and Fourier transform infrared spectroscopy (FTIR). Gastroretentive floating tablets of BG were prepared with the model drug propranolol HCl by direct compression methods. The prepared tablets were evaluated for all their physicochemical properties, in vitro buoyancy, in vitro drug release, and rate order kinetics. PBG 04 was selected as an optimized formulation based on its 12-h drug release and good buoyancy characteristics. The optimized formulation was characterized with FTIR, DSC, and PXRD studies, and no interaction between the drug and BG was found. Thus, the study confirmed that BG might be used in the gastroretentive drug delivery system as a release-retarding polymer.

    PMID: 24939276
    This case report demonstrates sequential periodontic, orthodontic and prosthodontic treatment modalities to save and restore deep horizontally fractured maxillary central incisor. The location of fracture was deep in the mucosa which reveals less than 2 mm of tooth structure to receive the crown. The procedures like surgical crown lengthening, endodontic post placement, orthodontic forced eruption, core build-up and metal-ceramic crown restoration were sequentially performed to conserve the fractured tooth. Forced eruption is preferred to surgical removal of supporting alveolar bone, since forced eruption preserves the biologic width, maintains esthetics, and at the same time exposes sound tooth structure for the placement of restorative margins.

  17. Eldecalcitol (ED-71), an analog of 1α,25-dihydroxyvitamin D3 as a potential anti-cancer agent for oral squamous cell carcinomas
    Shintani T, Rosli SNZ, Takatsu F, Choon YF, Hayashido Y, Toratani S, et al.
    J Steroid Biochem Mol Biol, 2016 11;164:79-84.
    PMID: 26444325 DOI: 10.1016/j.jsbmb.2015.09.043
    We have previously reported that 1,25(OH)2D3 inhibits NF-κB activity and thus inhibits growth of OSCC cells in serum-free culture and down-regulates HBp17/FGFBP-1 expression, which is important for cancer cell growth and angiogenesis. Here, we have investigated the effects of ED-71, an analog of vitamin D3 (VD) on OSCC cell lines in serum-free culture. It is known that ED-71 has a stronger inhibitory effect on bone resorption compared to VD and other VD analogs. To the best of our knowledge, there was no report examining the potential of ED-71 as an anti-cancer agent for OSCC. We found that ED-71 is able to inhibit the growth of cancer cell lines at a concentration of hundred times lower than calcitriol. As Cyp24A1 was reportedly induced in cancer cells, we measured the expression of CYP24A1 in OSCC cell lines (NA and UE), A431 epidermoid carcinoma and normal fibroblast cell (gfi) in serum-free culture. As a result, CYP24A1 mRNA and the protein expression in the OSCC cells treated with ED-71 increased in a dose-dependent manner. However, in vivo experiment, in which the A431 cells were implanted in mice, tumor formation was reduced by the ED-71 treatment with no significant difference between Cyp24A1 expression in the tumors of ED-71-treated and control group, as analyzed by western blotting and immunohistochemistry. These results suggest that ED-71 is a potential anti-cancer agent for OSCC.

    Primary biliary cirrhosis in combination with autoimmune hepatitis has been termed "overlap syndrome", but its diagnosis is challenging. We report a case of a 43-year-old lady who presented with a six-month history of jaundice and pruritus. She subsequently developed gum bleeds. Laboratory investigations revealed hypochromic microcytic anemia, abnormal coagulation profiles, elevated serum alanine transferase and alkaline phosphatase levels, and raised serum IgG and IgM levels. Her serum was also positive for anti-nuclear and anti-mitochondrial antibodies. The findings from her abdominal CT scan were suggestive of early liver cirrhosis and the histopathological examination results of her liver biopsy were consistent with primary biliary cirrhosis. The patient was treated with ursodeoxycholic acid and her liver function test parameters normalized after six months.

    Periodontal disease represents a group of oral inflammatory infections initiated by oral pathogens which exist as a complex biofilms on the tooth surface and cause destruction to tooth supporting tissues. The severity of this disease ranges from mild and reversible inflammation of the gingiva (gingivitis) to chronic destruction of connective tissues, the formation of periodontal pocket and ultimately result in loss of teeth. While human subgingival plaque harbors more than 500 bacterial species, considerable research has shown that Porphyromonas gingivalis, a Gram-negative anaerobic bacterium, is the major etiologic agent which contributes to chronic periodontitis. This black-pigmented bacterium produces a myriad of virulence factors that cause destruction to periodontal tissues either directly or indirectly by modulating the host inflammatory response. Here, this review provides an overview of P. gingivalis and how its virulence factors contribute to the pathogenesis with other microbiome consortium in oral cavity.

    Introduction: Oral squamous cell carcinoma (OSCC) is a major health problem worldwide. The overall survival rate remains at 50% despite numerous studies and various treatment modalities in OSCC. The presence of lymph node metastasis in OSCC is well established as an independent prognostic factor. This present study aims to investigate the association of four tumour antigens; FJX-1, GNα12, IFITM3 and MAGED4B with the sociodemographic and clinicopathological parameters of OSCC. The potential use of these markers as a prognostic indicator of patient sur-vival and lymph node metastasis in OSCC was explored. Methods: 35 cases of OSCC with available formalin-fixed paraffin-embedded (FFPE) specimens involving the tongue, buccal mucosa, gingiva, alveolus and floor of mouth were evaluated by immunohistochemistry for FJX-1, GNA12, IFITM3 and MAGED4B expression. Assessment of the expression of these tumour antigens was based on the cellular sub-site, intensity and percentage of staining in the OSCC samples. Results: The expression of all four tumour markers were expressed in all samples (n=35) but none statistically associated with any clinicopathological or socio-demographic parameters. Survival analysis using Kaplan-Meier test showed high expression of GNA12, IFITM3 and MAGED4B individually with poor prognosis in OSCC patients. A combination of markers, GNA12 and MAGED4B demonstrated a significant association with pa-tient survival in OSCC (p=0.014). Multivariate analysis after adjustment for selected socio-demographic factors (age, gender, risk habits and sub-sites of the oral cavity) revealed that high expression of both MAGED4B and GNA12 remained as an independent prognostic factor for poor prognosis in OSCC (HRR =5.231, 95% CI 1.601,17.084; p=0.006). Conclusion: We concluded that high combined expression of both marker (Gα12 and mAGED4B) might be used as an independent prognostic indicator in OSCC.
