    According to the 3rd edition of the international
    classification of headache disorders (ICHD3 2013),
    Trigeminal Neuralgia (TN) is classified into two types:
    1. Classical TN, purely paroxysmal 2. Classical TN
    with concomitant persistent facial pain. In this article,
    the authors describe a 47 year-old, male with unilateral,
    severe, recurring, electric shock-like pain involving left
    lower jaw, teeth and gingiva. Diagnosis of classical TN
    of the left 3rd division of the trigeminal nerve was made.
    The patient was treated with pharmacotherapeutic agents
    but without relief. Magnetic resonance imaging (MRI)
    of the brain showed medial vascular compression of left
    trigeminal pontine root entry zone caused by superior
    cerebellar artery. A microvascular decompression (MVD)
    surgery was done at the left trigeminal pontine root entry
    zone resulting in good relief of pain. This article highlights
    the differential diagnoses to be considered with TN and
    also emphasize the difference between the two types of
    the TN according to ICDH3 (2013). It also highlights the
    difference between classical TN purely paroxysmal with
    and without vascular compression by imaging techniques
    and their differing treatment modalities, which therefore
    should be reflected in future ICDH classification.

    Teaching is a complex activity which consists not only of giving instructions but also promotion of learning. Different students have different preference for learning styles. Dental educators must therefore attempt to mix and match their methods of teaching to accommodate students with differing learning styles to provide an opportunity to maximize their learning. This paper aims to share the writer's experience and students' perceptions towards a different mode of teaching/learning method. The Jigsaw Classroom method was employed on University of Malaya's third-year dental students during their Water Fluoridation lecture. At the end of the session, students were asked to reflect upon the learning experience and to inscribe their feelings. Initially, students showed their resentment towards the new learning style but their resistance changed once they got into a group and started to learn from each other. In the reflective essay, most students expressed that learning through teaching and discussing as required in the Jigsaw method enhanced their understanding of the topic and they claimed that they were able to retain the information better. In this study, the Jigsaw method proved that learning in the lecture hall can be fun, educational and enriching.

    Supernumerary teeth have a genetic predisposition
    with a predilection for males. This article reports an
    uncommon radiological finding in a non-syndromic
    sibling pair who presented with supernumerary teeth
    of different morphologies on opposite and different
    regions of the dental arches. A 14-year-old Chinese
    male presented with a conical supernumerary palatally
    placed between the upper right central and lateral
    incisors. His older brother had unerupted bilateral
    supplemental supernumerary teeth between the roots
    of the lower second premolars and first permanent
    molars. Trends of the phenotypic presentation of
    familial non-syndromic supernumerary cases are
    discussed. Familial supernumerary teeth have been
    suggested to be due to autosomal dominance or
    recessive traits. Variation in the numeral, spatial and
    morphological phenotypic expressions suggests a
    multifactorial model of multiple genetic, epigenetic
    and environmental influences. Clinicians need to be
    mindful of the possible phenotypic variations that may
    present when treating cases with family history of
    dental anomalies.

    The canine teeth of the mature ferret have closed apices. They are easily accessible for operating purposes and are sufficiently large, allowing conventional cavity preparation techniques to be prepared using ordinary dental instruments. Handling of the ferret is relatively easy since it becomes quite tame after a period of time. The body weight in male is greater and the teeth larger than those of the female. The cost of purchase and maintenance of the ferret is also inexpensive. For all these reasons, the ferret male is animal of choice in dental experiments.

    Objective: This study examined the influence of visual art therapy techniques in reducing anxiety level
    among 4 to 6 years old paediatric dental patients.
    Methods: Eleven subjects were selected among 4 to 6 years old paediatric dental patients. The initial
    reaction towards dental procedure/treatment was evaluated using Frankl Behavior Rating Scale. The
    anxiety level was assessed by using Malay-Modified Child Dental Anxiety Scale (MCDASf
    ) to measure
    a child situational anxiety of pre- and post-treatment. Visual art making activities included free drawing,
    clay moulding and collage technique. The participant reaction to dental treatment was assessed by using
    Frankl Behavioural Rating Scale for two subsequent independent visits in two weeks interval. Median
    and Ordinal Test ranked the variables score of behavioural reaction towards dental treatment and anxiety
    level.
    Results: Play-doh (PD) subjects could accept dental procedures more if compared to free drawing (FD)
    and storytelling by collage (ST) subjects, which has lower post treatment-median scores in Visit 1 and
    Visit 2, FD and ST subjects need more time to show positive attitude towards dental treatment.
    Conclusion: These findings suggest dental anxiety level of children aged 4 to 6 years old reduced after
    the art therapy and play-doh(clay-moulding technique) is the art making activity of choice among 4 to 6
    years old paediatric dental patients.

    The objective of this study was to determine the effect chewing of two differently sized commercially available meswak might have on flow rate and pH of whole saliva. Twenty subjects participated in this study. They were distributed into two groups (A and B). Subjects in both groups A and B were asked to first chew on either a sized #1 or #2 cotton roll followed by the chewing of an equivalent sized piece of meswak (approximately 5 mm. and 10 mm. diameter) respectively. For subjects in group A, no differences in mean flow rate was seen after both the chewing regimes. In group B however, the increase in mean flow rate after the chewing of meswak compared to cotton roll was statistically significant at p < 0.05. Statistically significant lower values for pH were registered after the chewing of meswak compared to cotton roll in both groups A and B at p

    Background: The high prevalence and impacts of orofacial pain (OFP) have caused major sufferings to individuals and society. The purpose of the study was to investigate the problems and impacts of OFP among a group of Malaysian aborigines. The objectives were to determine (i) the prevalence, aetiology, duration, severity, types and persistence of OFP during the past 3 months preceding the study; (ii) its associated impact on daily performance; and (iii) the measures taken for pain relief.
    Methods: This is a cross sectional study carried out in Kuala Lipis, Pahang involving 6 villages of Orang Asli Bateq and Semai. Study sample was chosen using convenient sampling including adults aged 16 years and above. Participants were invited for an interview using structured questionnaire followed by clinical examination. Data analysis was carried out using SPSS ver12.
    Results: Response rate was low at 20% (n = 140). Over one-quarter (26.4%) of the sample experienced OFP in the previous 3 months. Toothache was found to be the main aetiology (83.3%) followed by gingival pain (18.9%), temporomandibular joint (10.8%) and facial pain (8.1%). Mean duration of pain was 9.8 days for toothache, 162.4 days for gingival pain, 7.3 days for TMJ and 5.7 days for facial pain. Of those who had OFP, over half rated the pain as moderate (37.8%) and severe (29.7%) and most of the pain was ‘intermittent’ in nature (81.1%). Over half (62.2%) admitted the pain had disappeared during the interview. In terms of pain relief, 56.8% of the sample used traditional medicine. The pain had impacted on the chewing ability (70.3%, p=0.01), ability to sleep at night (73.0%, p<0.001), levels of anxiety (70.3%), ability to perform daily chores (33.3%) and social life (35.1%) of the Orang Asli sample.
    Conclusion: This study suggests the prevalence of OFP was high among the Orang Asli sample, which imposed considerable physical and psychological impacts on daily life.

    The aim of this study is to evaluate the treatment outcome using fixed and removable appliances, in the Faculty of Dentistry, University of Malaya (U.M.). The study models of 25 fixed and 30 upper removable appliance cases, with complete written records were examined before and after orthodontic treatment using the PAR (Peer Assessment Rating) Index. All the data were analyzed using the Statistical Package for Social Sciences (SPSS) for Windows. Eighty five percent of the cases selected as sample were either 'improved' or 'greatly improved'. Among the 10 cases which were 'greatly improved', all had high pre-treatment PAR points (> 35 PAR points). Conversely, all the eight cases classified as 'worse or no different' were with low pretreatment PAR scores « 20 PAR points). The mean treatment duration in this study was 23. I months, ranging from 2 months to 78 months. The results of this study showed that the standard of treatment in this Faculty were fairly acceptable.

    Pilomatrixoma is a relatively common benign tumour arising from the matrix and inner sheath of a normal hair follicle as well as hair cortex. It is usually presented as a superficial, solitary, firm mass which is asymptomatic and slowly growing. It accounts for about 0.2% of all routine skin specimens and may poses a diagnostic challenge as it may resemble other common benign lesions found in the head and neck region. We report a case of a 33-year old men presented to us with a pilomatrixoma of the right cheek, surgical management and histological findings.

    Chronic idiopathic facial pain is the diagnosis given to a group of orofacial pain of psychogenic origin which includes atypical facial pain, facial-arthromyalgia, atypical odontalgia and oral dysaesthesia. Despite various biochemical findings, the condition remains poorly understood, but we have begun to understand the nature of these patients. This review discusses the possible aetiology of the disease through various biochemical and clinical findings. The contribution of behavioural and psychological factors to the clinical course of the disease are described. The type of adverse life events that predispose people to the disease and their potency are briefly mentioned. The current diagnostic approach for the disease is also mentioned. Treatment includes antidepressant medication, physiotherapy, bite-guards and analgesics. The problems encountered in the long-term management and outcome studies of these patients include drop-outs, non-compliance and denial.

    The standard procedure for alveolar cleft closure in cleft lip and palate patients is by alveolar bone grafting (ABG) where the residual opening of oronasal fistula in the palate is also closed simultaneously. Occasionally there is a situation of soft tissue inadequacy and attempt to close the fistula at the same procedure as ABG may compromise the result of the bone graft itself. An unforeseen leakage at the closure may cause graft infection leading to failure. This article reports on a technique where alveolar bone grafting was done without closure of residual palatal fistula to provide adequate soft tissue coverage for the grafted bone. This may reduce the risk of leakage at the oral mucosal coverage of the graft . The residual palatal fistula will be closed at later stage by muco-palatal flap or tongue flap. We reported on a case of a failed ABG which was reconstructed using this technique. Various other techniques to ensure success of ABG were also discussed. Conclusion: The alveolar bone grafting without closure of oro-nasal fistula reduced the risk of failure of ABG in a wide alveolar cleft.

    Differential diagnosis of orofacial pain is crucial, as the course of each process and its clinical management varies markedly. A case is illustrated here of trigeminal neuralgia in a 49-year-old Indian female whose complaint was initially diagnosed as dental pain leading to sequential extractions of her right mandibular and maxillary molars but with no pain abatement. Subsequent neurological assessment diagnosed her complaint as trigeminal neuralgia but pain remained poorly controlled even with high doses of carbamazepine and gabapentin. A dental referral and orthopantomographic examination revealed multifocal sclerotic masses in her jaws, suggestive of florid cemento-osseous dysplasia (FCOD). Right mandibular incisional biopsy confirmed the diagnosis. A decision was made to curette the right mandibular masses and lateralised the right inferior dental nerve. Follow-up disclosed considerable pain reduction. This case raises the issue as to whether the sclerotic bone masses in FCOD may have caused nerve compression which
    aggravated her neuralgic pain.

    Mental nerve neuropathy is an important presenting complaint that may be encountered by dental surgeons in their daily practise. There are various pathological processes that could bring about this symptom, ranging. from simple dental cause to vague, life threatening diseases. We present three cases of mental paraesthesia of different aetiologies. A literature review on mental nerve neuropathy related to malignancies and infection is discussed. The importance of a thorough chair side history taking, clinical examination and relevant investigations are emphasised in a suggested clinical approach to obtaining the diagnosis of a numb chin.

    Much interest has been generated in tooth-co loured inlays/onlays especially with patient's concern for esthetic appearance and the dentist's appreciation for additional strength of the restored tooth, together with bonding. Many types of tooth-coloured inlay/onlay restorations are available but none have undergone extensive and long term research. The different types of inlay/onlay restorations together with steps in their preparation are presented in this paper.

    This study is conducted to compare two resin luting cements (Rely XTMARC,3M and Compolute™ESPE) on their microleakage with one composite inlay system (Filtek™ Z250 Universal Restorative Materials, 3M). Thirty conventional inlays, Class II MOIDO cavity with gingival margin I mm above the cementoenamel junction, were prepared in premolar teeth. The composite inlays were fabricated directly on the prepared teeth using layering technique. Fifteen of the inlays were cemented with RelyTMX ARC and fifteen with Compolute™ (ESPE). The specimens were kept at 370 C for 10 days before thermocycling and immersed in methylene blue 2% solution for 24 hours. The teeth were sectioned mesio-distally. The site and degree of leakage of each section was scored using a visual scoring system under a stereomicroscope at a magnification of 1.5X. Results showed that there was no significant difference in'leakage extent (p>O.05), between Rely X™ARC and Compolute™. For both materials, leakage occurred most commonly within the enamel surface and between the cement-tooth interfaces. None of the leakage occurred between inlay - cement interface. There is no significant difference in the extent of leakage between Rely XTMARC compared to Compolute™.

    This study aim to evaluate antimicrobial efficacy of sodium hypochlorite (NaOCl) and ozonated water against Enterococci faecalis biofilm. The bacterial biofilm was exposed to 2.62%, 1.31% NaOCl and 0.1 ppm ozonated water over a range of time periods. The presence of viable cells was determined by enumeration of colony forming units (CFU). All experiments were repeated four times (n=4). The effectiveness of the agents was compared using nonparametric Kruskal- Wallis test. The result revealed that 2.62% of NaOCl can completely kill E. faecalis biofilm in 15 minutes whereas 1.31 % NaOCl required a longer time to produce such effect. 0.1 ppm ozonated, however, did not exhibit any antimicrobial effect within the period of time tested. From this study, it can be concluded that 0.1 ppm ozonated water was not comparable with 2.62% and 1.31% NaOCl in antimicrobial efficacy against E. faecalis biofilm.

    Tumours that occur in the oral cavity may contain granular cells as a component of their pathology. A more common granular cell lesion occurring in the head and neck region is the granular cell tumour (GCT) that usually arises in the tongue or the buccal mucosa. Granular cell tumours are very rare in the parotid gland with only 11 cases previously reported in the English literature. We report a case of a benign tumour involving the parotid gland of a young female patient. The case was diagnostically challenging due to the large proportion of granular cells masking the underlying pathology. Histopathological features and immunohistochemical analysis favoured a diagnosis of a benign GCT. The present report provides an insight into the differential diagnosis and attempts to characterise the granular cells with the use of the wellestablished immunohistochemical markers and conventional histopathological techniques.

    Side effects such as abrasion of the dental hard tissue have been frequently observed following the extensive use of mechanical cleansing. As promising antiseptics like chlorhexidine produces extrinsic dental staining on long term usage, there has been increasing interest and research generated towards chemically based stain removing agents. This invitro studyexamined whether some commercial oral hygiene products could inhibit chlorhexidine derived stain independent of any mechanical cleansing action. Perspex blocks were soaked in triplicate in chlorhexidine solution for 2 minutesand stain inhibition by these products was determined by further soaking the blocks in productl water slurries for 2 minutes and finally in tea solution for I hourly periods. The optical density (OD) of each specimen was determined at each hourly interval by spectrophotometry at 395 nm and the mean values obtained. At the end of the study, most of the products inhibited stain compared to water control and there was a variation in the stain inhibitingefficacyof the products. It is thus concluded that oral hygiene products like dentifricesand mouthrinses can inhibit chlorhexidine derived extrinsic dental stain to a variable degree through a chemical action by contained ingredients.
