    Langerhans Cell Histiocytosis (LCH) refers to a group of lesions presenting with a spectrum of clinical. features but sharing similar histology. These lesions are rare and treatment has been quite variable with current treatment protocol recommended being dependent on whether it is a unifocal or multi focal bone disease or a multi focal multisystem disease. However, the clinical presentations of LCH are variable and the decision to place into the appropriate clinical types may sometimes be masked by the non-discovery of all the lesions. In the oral maxillofacial area, the clinical features of these lesions may further pose a problem by nondescript manifestations as dental/periodontal/oral mucosal disorders. These oral findings may sometimes lead to inappropriate choice of treatment and delay in the diagnosis of all the lesions involved. This paper describes one such case where LCH manifest itself as a periodontal disease thus leading to delay in identifying all the sites involved and consequently a delay in id~ntifying the appropriate clinical type.

    Tobacco use is linked with many serious illnesses, such as cancer, cardiopulmonary diseases, as well as with many health problems. Every year, the use of tobacco products causes a heavy toll of deaths and severe human disease worldwide. One of the many health problems linked to tobacco use is its detrimental impact on oral health. Tobacco causes a whole series of oral health problems, ranging from life-threatening (precancerous changes leading to oral cancer) and serious (periodontal disease, teeth decay) to social (bad breath). Tobacco is consumed through the mouth in a variety of forms, varied from smoked tobacco to smokeless tobacco chewing on itself or combined with areca nut. All these forms of tobacco have damaging effects on the oral health. The most significant preventive measure to prevent the oral health problems caused by tobacco use is to stop using tobacco products. The risk of developing oral cancer drops rapidly when a smoker ceases tobacco use. After ten years of not using tobacco, an ex-smoker/user's risk of oral cancers is about the same as that for someone who has never smoked. To stop using tobacco products is not an easy task. Fortunately, there are a number of therapies available to assist in quitting of tobacco. It is important to remember that, while it will be difficult, ceasing to use tobacco has immediate health benefits, including increased life expectancy and reduced risk of tobacco related diseases and conditions.

    The role of smoking as a contributory factor in the progression of the periodontal disease process has long been suspected and recently a large number of studies have been published in the dental literature regarding this possible role. Much of the literature has also indicated that smokers affected with periodontitis respond less favorably to periodontal treatment be it non-surgical, surgical and regenerative. This paper will review the current literature regarding the effects of smoking on various aspects of the periodontal disease process and present an explanation for the possible association between smoking and the progression of periodontitis.

    The objective of the study was to attempt to verify the cause of self-reported oro-facial pain among 12-yearold children, objectively via a clinical examination. This is a descriptive, cross-sectional survey using a combination of self-reported questionnaire, face-to-face interview and clinical oral examination. The children were first asked to answer a self-filled questionnaire about their oro-facial pain experience in the past 4- weeks. In order to verify its cause, a clinical examination and an interview followed. Normative oral health status data was also collected. The sample was 1492 Malay schoolchildren with diverse socioeconomic background from the states of Johore, Kelantan and Sabah. The sample size for each state was calculated to give a sampling error of not more than 5 %. In each state, quota sampling was done to achieve a balanced distribution between gender and location. The data collected were normative status for caries, periodontal disease and traumatized teeth. Orofacial pain experience represented the subjective status for oral well-being. The cause of pain was confirmed through a clinical examination. The normative oral health status data implies a very low untreated disease and good oral health among the schoolchildren. However the subjective health status, as reflected by the prevalence of pain suggested that oro-facial pain and suffering was high (27.3%) with about 49% "of moderate and severe" intensity. The two main causes were caries and mouth ulcers. However in about onequarter of pain cases, diagnosis cannot be confirmed in the field survey setting. More than one-half of those with pain experienced disturbed sleep and study. It was concluded that overall oral health status and well-being can be better described if normative data is complemented with subjective data such as pain prevalence. The study shows that the majority (more than 75 %) of cases of subjective pain can be objectively verified in a field epidemiology survey setting. The reliability of the subjective data can be improved by a clinical examination as compared to unverified self-report. The study also confirms that the major source of oro-facial pain among the 12 year-olds were caries and mouth ulcers.

    Objective: This study aimed to assess the awareness of periodontal disease and level of knowledge of the relationship between smoking and periodontal disease amongst subjects who were smokers verses non-smokers.
    Methods: A questionnaire looking at knowledge of respondents regarding gum disease and knowledge and awareness about oral impacts of smoking on periodontal disease was developed and pretested in Dental Faculty University of Malaya. Basic Periodontal Examination (BPE) index was used to assess periodontal status.
    Results: The questionnaire was answered by 130 subjects. Prevalence of smoking was 14.6%. A total of 58.6% non-smokers and 57.9% smokers knew about periodontal disease. However, only 26.1% non-smokers and 10.5% smokers knew that the cause for periodontal disease was plaque. More non-smokers than smokers knew that smoking affected periodontal health (80.2% and 68.4% respectively) (p>0.05) and tooth mobility was an effect of smoking on periodontal health (27.0% and 0%) (p<0.05). Regarding source of information on effect of smoking on periodontal health, 63.2% smokers and 63.1% non-smokers reported obtaining information through the mass media. However, only 31.6% smokers and 28.8% non-smokers were informed by their dentist.
    Conclusion: The awareness of periodontal disease and knowledge of the relationship between smoking and periodontal disease was low in this selected population of smokers and non-smokers.

    OBJECTIVE: To investigate effects of HIFU on macrophage phenotype, surface micro-topography and nano-scale surface mechanical properties of dental cementum.

    MATERIALS AND METHODS: Root discs (2 mm thickness) were cut apical to CEJ and sectioned into quadrants. HIFU setup with bowl-shaped piezo ceramic transducer submerged in a water tank was used for exposure on each specimen for 15 s, 30 s or 60 s. The specimens of the control group were left without any HIFU exposure. HIFU was generated with a continuous sinusoidal wave of 120Vpp amplitude, 250 KHZ resonance-frequency and highest ultrasonic pressure of ∼10 bar at the focus. Specimens for SEM were viewed, and micro-topography characterization performed, using AFM and Ra parameter and surface area (SA) calculated by specialized SPM surface analysis software. For nano-indentation testing, experiments were carried out using AFM. Macrophage cell isolation and culturing was performed on cementum to receive the HIFU treatment at different time periods. Raman spectroscopy were scanned to create spectra perpendicular to the cementum substrate to analyze generation of standard spectra for Raman intensity ratio of hydroxyapatite normalized to the peaks ν1 960 cm-1. Data was expressed as means ± standard deviations and analyzed by one-way ANOVA in term of Ra, SA, H and Er. Different points for fluorescence intensity ratio were analyzed by Raman using Wilcoxon rank sum test.

    RESULTS: HIFU exposure at 60 s removed the smear layer and most of cementum appeared smoothened. AFM characterisation, showed a slight decrease in the irregularity of the surface as exposure time increased. Intact macrophages can be identified in control and all experimental HIFU groups. The level of fluorescence for the control and HIFU 15 and 30 s were low as compared to HIFU 60 s.

    CONCLUSION: If HIFU can be successfully implemented, it may be a possible alternative to current methods used in periodontal therapy to achieve smooth root surfaces.

    BACKGROUND: The purpose of this study was to determine the oral health status and treatment needs of elderly hostel residents in Melbourne.

    METHOD: One hundred and seventy-five subjects aged 65+ were selected from 20 hostels within a 10 km radius of Melbourne's central business district.

    RESULTS: Subjects were clinically examined and interviewed using a standard questionnaire. In the course of the clinical examination, coronal caries, root caries, periodontal disease, denture status and related treatment needs were assessed. The mean age of the subjects was 83.7, the majority of whom were female (80 per cent). About 35 per cent of the sample were dentate. The mean number of teeth present among dentate persons was 13.8, the mean coronal caries experience was 24.9 DMFT and mean root caries was 2.3 R-DF. Of the dentate subjects, 46 per cent required at least one restoration for coronal caries and 30 per cent required at least one restoration for root caries. Most dentate subjects had calculus and none had deep pockets, therefore, indications for periodontal treatment did not include complex care. More than 50 per cent of lower full dentures were retained unsatisfactorily and about half of the total number of subjects required prosthetic treatment.

    CONCLUSIONS: Although there was a high number of treatment needs, most requirements involved simple technologies that could be delivered by auxiliaries.

    BACKGROUND: The current retrospective cross-sectional study investigated 5-18-year treatment outcomes in subjects who did not complete a recommended course of periodontal therapy.

    METHODS: Sixty-five subjects who voluntarily discontinued therapy were recalled. The subjects' demographic data and dental history since discontinuation of periodontal treatment were collected via questionnaires. The subjects' periodontal condition, radiographic data and individual tooth-based prognosis at pre-discontinuation and recall were compared.

    RESULTS: A total of 229 teeth had been lost over time, mainly due to periodontal reasons. Upper and lower molars were most frequently lost. Rate of tooth loss (0.38/patient per year) was comparable to untreated patients. Deterioration in periodontal health in terms of increased percentage of sites with bleeding on probing (BOP) and sites with probing pocket depths (PPD) of 6 mm or more at re-examination was observed. Positive correlations were found between tooth loss and: (i) years since therapy discontinued; (ii) percentage of sites with PPD of 6 mm or more at pre-discontinuation; and (iii) at re-examination. Percentage of sites with PPD of 6 mm or more at recall was positively correlated with periodontal tooth loss and negatively correlated with percentage of sites without BOP.

    CONCLUSIONS: Patients not completing a course of periodontal therapy are at risk of further tooth loss and deterioration in periodontal conditions over time.

    BACKGROUND: There is a limited understanding about the oral health of patients with facial burn, hence the aim was to describe the oral health status and the related risks factors.

    METHODS: This cross-sectional study had randomly and systematically recruited facial burn patients from the Burn Care Center, Pakistan Institute of Medical Sciences, Islamabad, from June of 2016 to July of 2017. Intraoral examination recorded the DMFT, CPI and OHI-S. Information on the socio-demographic status, self-perceived oral health, oral health behaviours were collected using a self-administered questionnaire and; the burn characteristics were obtained from the patients' medical record. The t-test, ANOVA, SLR, and chi-square test were used to examine the relationship between oral health and each factor. A parameter was derived from the clinical indices using the principal component analysis and used in the multiple linear regression analysis to determine the important factors associated with oral health status.

    RESULTS: A total of 271 burn patients (69% female and 31% male) had participated in the study. All of the participants had caries with mean DMFT = 10.96 (95%CI: 10.67, 11.25). There were 59.0% (95%CI: 53.15, 64.93%) and 66.1% (95%CI: 60.38, 71.73%) of the participants who had periodontitis and poor oral hygiene respectively. About 79 and 80% of the participants rated their dental and periodontal status as poor. About 78% reported brushing once daily and 89% did not practice regular dental visit. The DMFT, CPI and OHI-S were associated with the burn characteristics and oral health behaviours (p

    The urban low income has often been assumed to have the greatest dental treatment needs compared to the general population. However, no studies have been carried out to verify these assumptions. This study was conducted to assess whether there was any difference between the treatment needs of an urban poor population as compared to the general population in order to design an intervention programme for this community.

    Whether "periodontal disease" can be considered as an independent risk factor for head and neck cancer (HNC) remains controversial. The aim of the current meta-analysis was to quantitatively assess this relationship in order to determine whether this represents a true risk factor, with implications for cancer prevention and management. PubMed, Scopus, and Embase databases were systematically searched. Selective studies were reviewed, and meta-analysis was performed to estimate the pooled odds ratio (OR) with 95% confidence intervals (CIs) on eligible studies using a random effects model. In total, 21 eligible observational studies (4 cohorts and 17 case-controls) were identified for qualitative synthesis after a review of 1051 articles. Significant heterogeneity could be identified in measures utilized for reporting of periodontal disease. Meta-analysis performed on nine studies that employed objective measures for reporting periodontal disease demonstrated a significant association between periodontal disease and HNC [OR 3.17, 95% CI, 1.78-5.64]. A diseased periodontium represents an independent risk marker, and a putative risk factor, for HNC. Prospective studies with standardized measures of periodontal disease severity and extent, integrated with microbiological and host susceptibility facets, are needed to elucidate the mechanisms of this positive association and whether treatment of the former influences the incidence and outcomes for HNC.

    Assessment of dental treatment needs has predominantly been based on the normative approach, despite its numerous limitations. The sociodental approach is a more rational method of needs assessment as it incorporates broader concepts of health and needs and behavioural propensity. This study compares estimates of periodontal dental treatment needs and workforce requirements for different skill mixes using normative and sociodental approaches among a sample of adults in Malaysia.

    The influx of refugees from Vietnam to the industrialized countries has attracted a certain interest to studies describing the oral health status of these population groups. The present study comprises 361 refugees arriving in Malaysia from Vietnam and collected immediately at the refugee camp on Pulau Bidong. Dental caries, calculus, gingival bleeding and loss of periodontal attachment were recorded. Mean dmft increased from 1.3 for 0-2-yr-olds to 7.4 for 3-5-yr-olds. For 6-9-yr-olds mean DMFT was 2.4 while it ranged between 8.5 and 10.10 for the older age groups. The frequency of secondary lesions was high for all age groups. Calculus increased consistently with age, while gingival bleeding was common even in the youngest age group. Loss of periodontal attachment greater than or equal to 6 mm was rare in all age groups except the oldest (45 yr or older). A strategy for oral health care for these population groups is discussed.

    Objectives: Periodontitis is a chronic disease which remain undiagnosed and untreated without proper examination and referral to specialist clinic for further management Therefore, this study was conducted to evaluate the pattern of referrals to Universiti Teknologi MARA (UiTM) Periodontal Specialist Clinic. Materials and methods: A total of 176 periodontal cases referred to UiTM Periodontal Specialist Clinic in year 2011 and 2016 were identified and patient’s referral forms were collected. The data obtained were the referred cases from undergraduate student clinics, other specialist clinics, UiTM primary dental care clinic and private dental clinics. Descriptive data analysis was conducted using frequency distribution by SPSS. Chi square analysis was used to evaluate the association of source of referral, diagnosis and reason for referrals to Periodontal Specialist Clinic. Results: There was increased referral cases to Periodontal Specialist Clinic in 2016 (86.9%) compared to 2011 (13.1%). Most referral to Periodontal Specialist Clinic were received from faculty’s undergraduate student clinic in both 2011 and 2016 (46%), followed by other specialists (27.3%), primary care clinic (25.6%) and private practice (1.1%). 96% of cases were referred for intervention by periodontist as more than half of the cases were referred for the non-surgical periodontal treatment. Chi square analysis showed the association between source of referral and reason for referral was statistically significant (p value=0.000). Conclusion: Proper periodontal screening in all patients and necessary referral to specialist clinic is crucial to prevent undiagnosed periodontal disease.

    Background. Several studies in the last decades have focused on finding a precise method for the diagnosis of periodontal disease in its early stages. Aim. To evaluate from current scientific literature the most common and precise method for gingival crevicular fluid (GCF) sample collection, biomarker analytical methods, and the variability of biomarker quantification, even when using the same analytical technique. Methodology. An electronic search was conducted on in vivo studies that presented clinical data on techniques used for GCF collection and biomarker analysis. Results. The results showed that 71.1%, 24.7%, and 4.1% of the studies used absorption, microcapillary, and washing techniques, respectively, in their gingival crevicular fluid collection. 73.1% of the researchers analyzed their samples by using enzyme-linked immunosorbent assay (ELISA). 22.6%, 19.5%, and 18.5% of the researchers included interleukin-1 beta (IL-1β), matrix metalloproteinase-8 (MMP-8), and tumor necrosis factor-alpha (TNF-α), respectively, in their studies as biomarkers for periodontal disease. Conclusion. IL-1β can be considered among the most common biomarkers that give precise results and can be used as an indicator of periodontal disease progression. Furthermore, paper strips are the most convenient and accurate method for gingival crevicular fluid collection, while enzyme-linked immunosorbent assay can be considered the most conventional method for the diagnosis of biofluids.

    Parvimonas micra is an important oral microbe that has the ability to grow and proliferate within oral biofilms and is involved in periodontal disease, leading to gingival bleeding, gingival recession, alveolar bone loss, and tooth mobility. However, occasionally these normally oral pathogens can cause infections at other sites in the body. We present the genome sequence of Parvimonas micra strain A293, a smooth Parvimonas micra strain isolated from an abdominal abscess from a patient at Barts Hospital, London, United Kingdom.
