    Aim: This study evaluates perception toward facial appearance in dentofacial deformity and the need for orthognathic surgery among the public with and without dental backgrounds. Materials and Methods: A questionnaire consisting of 12 facial photographs of cases with dentofacial deformity or malocclusion in varying severity was used. A hundred individuals were selected to answer the questionnaire. The perception of facial appearance (FAS), treatment need score (TNS), and knowledge regarding dentofacial deformity were used for the evaluation. Results: Significant differences were found between dental and non-dental when the respondents' knowledge in all the questionnaire items ([Formula: see text].05) was assessed. However, no significant difference was found in the mean of FAS and TNS in all the presented cases (normal, borderline, severe). Pearson correlation between perceived FAS and TNS was statistically negative for severe and normal cases, whereby a decrease in FAS for severe cases showed an increase in TNS, and an increase in FAS for normal cases showed a decrease in TNS. Conclusion: Respondents with dental background had sound knowledge of dentofacial deformity. A poorly attractive respondent with dentofacial deformity showed a greater need for orthognathic surgery.

    Like dental caries, epidemiological assessment of periodontal disease is important for purposes of recognizing the extent of the disease in the population as well as a basis for planning and evaluating preventive and treatment programmes. while present day measurement methods for dental caries are excellent such is not true for periodontal diseases. This paper reviews the development and usefulness of different indices for the assessment of periodontal disease and treatment needs in epidemiological investigations.

    BACKGROUND: Dental and maxillofacial injuries are one of the areas of concern highlighted in the Malaysian National Oral Health Plan 2011-2020. General dental practitioners (GDPs) have the responsibility of diagnosing and assessing dental trauma and determining the prognosis and outcomes of trauma along with its management. The purpose of this study was to evaluate the knowledge base and preferred methods of general dental practitioners regarding the management of avulsed tooth.

    METHODS: A random convenient sampling methodology was employed for sample selection. A pre-tested 11-item questionnaire was validated on the dental officers. The survey was distributed to 182 GDPs attending the annual Malaysian Dental Association conference in January 2010. The data obtained was statistically analyzed using descriptive analysis and logistic regression was employed to predict the probability of achieving high scores.

    RESULTS: A total of 182 general dental practitioners participated in the study, with the majority being female (n=153, 75%). The place of practice significantly affected the knowledge score. In the group that scored more than 80 points (n=84, 46%), 76% of them worked with government hospitals. Age, work duration and number of traumatised teeth previously treated had no significant effect. The odds ratio for place of practice indicates that respondents who work in government hospitals are 3.6 times more likely to score more than 80 points compared to those who worked in private clinics (OR=3.615, P=0.001).

    CONCLUSION: The knowledge level on the management of avulsed tooth among general dental practitioners in Malaysia needs to be improved. Strategies in improvement of the Malaysian dental educational system, continuous dental educational activities and utilisation of guidelines on trauma management should be recommended to increase the knowledge level of avulsed tooth management to ensure good treatment outcomes.

    CLINICAL IMPLICATION: Trauma prevention and further education regarding the management of avulsed tooth is an essential requirement to improve general dental practitioners knowledge and clinical skills.

    This study is aimed to evaluate the accuracy of Demirjian method in estimating the chronological age of male and female Kelantanese Malay children between 6 and 16 years of age and to establish a new dental age (DA) curve if the Demirjian method was not found to be accurate. About 905 panoramic radiographs of healthy Malay children between 6 and 16 years of age were collected from the radiographic unit in the Hospital Universiti Sains Malaysia (HUSM) and the orthodontic clinic in Hospital Kota Bharu (HKB). Children who had any disease affecting the dental development, or have agenesis in the lower arch and poor quality radiographic images were excluded. The results showed that Demirjian method overestimated the chronological age (CA) by 1.23 years for boys and 1.20 years for girls and it was less accurate for the Kelantanese Malay children. Thus new standard curve were produced and tested on external samples. Results showed that the mean difference between the chronological age and DA is about 0.17 years for boys and 0.11 years for girls. DA was more advanced in the Kelantanese Malay boys and girls as compared to French-Canadian children in all age groups. It is concluded that the Demirjian method tends to be less accurate in estimating the chronological age in Malay children. The new curve that was produced is more applicable to the Kelantanese Malay children.

    Head and neck cancer is becoming a more recognizable pathology to the general population and dentists. The modes of treatment include surgery and/or radiation therapy. Where possible, pretreatment dental assessment shall be provided for these patients before they undergo radiation therapy. There are occasions, however, whereby head and neck cancer patients are not prepared optimally for radiation therapy. Because of this, they succumb to complicated oral complications after radiation therapy. The management of xerostomia has been reviewed in Part I of this series. In this article, the management of dental caries, a sequalae of xerostomia following radiation therapy is reviewed.

    The aim of this retrospective study is to report on the prevalence of post-extraction complications among patients attending the Oral Surgery outpatient clinic of the Faculty of Dentistry, University of Malaya over a 12-month period from January to December, 1992. The prevalence of post-extraction complications which required further treatment was only 3.4% (n = 100), out of a total of 2968 patients who had extraction of one or more permanent teeth. Analysis based on complete clinical reports (n = 79) showed that dry socket accounted for nine out of ten cases of post-extraction complications. However the aetiology was largely unknown. No obvious association with medical history could be made. Lower teeth were more likely to have complications. The most common teeth associated with dry socket were the molars (76%) and premolars (19%). The most common molars to be affected are the first, followed by the third and lastly the second molars. A brief review of current aetiological factors of dry socket was discussed.

    Although the patterns of dental disease is gradually changing, caries and periodontal disease still account for the most important reason for extractions in most countries. However their relative contributions towards overall tooth mortality figures varies. The aim of this study is to investigate the types of teeth usually associated with extractions due to caries or periodontal disease and its relation to the age at which the tooth was lost. The highest proportion of extractions due to caries occurred between 21 to 30 years of age while that for periodontal disease occurred between 41 to 50 years. For caries, the greatest proportion of extractions involved the posterior teeth. The most frequently extracted teeth due to caries are the molars, in particular the first permanent molar. However, for periodontal disease a slightly greater proportion of anterior teeth were lost than the posteriors. This trend is more marked in the lower jaw than the upper. Overall, extractions related to caries tend to increase posteriorly, while that for periodontal disease tend to increase anteriorly.

    Samples of stimulated whole saliva were obtained from ninety-four 12-14-year-old school children living in inner London to evaluate if there was a correlation between Streptococcus mutans counts in saliva with plaque amount, gingival inflammation and caries experience. S. mutans counts were obtained by a dip-slide method (Dentocult 'Strip Mutans') in which the count was expressed as 0, 1, 2, 3, or 4 based on visual estimation of the colony density. There was no association between counts' of S. mutans in saliva with plaque amount and gingival inflammation. However, there was a significant trend of increased decayed, missing, filled surfaces (DMFS) with increasing S. mutans counts.

    A case report of sequestra formation in the oral cavity most probably as a sequelae of periodontal abscess in a diabetic patient is presented. The sequestra probably formed as a complication of uncontrolled diabetes mellitus rather than erythroleukemia. The lesion was located at the bifurcation area of the lower left second molar. Removal of the sequestra, scaling and a course of antibiotics managed to control the lesion.

    An important relationship should exist between the periodontist and restorative dentist. Periodontics and restorative dentistry should not be divisible and all forms of restorations, from a simple filling to a complex precision-retained bridge, should be performed with the health and biology of the periodontium in mind. A very crucial concept which should be borne in the mind of every restorative dentist is the concept of biologic width.

    Any foreign body in the paranasal sinuses can cause chronic complications. It is therefore important to remove these foreign bodies meticulously. Various approaches are available to accomplish this. This article is a case report of a patient who had gutta-percha as a foreign body in left maxillary sinus, after a gutta-percha point had been used to trace a sinus to confirm that it was an oroantral fistula. Traditional surgical approaches to the maxillary sinus require invasive techniques, such as radical antrostomy and the Caldwell-Luc approach. These may result in further complications and morbidity. The gutta-percha point in this case report was removed endoscopically in an otolaryngology clinic with local anaesthesia using a sublabial antroscopy. There is only one case reported in the dental literature regarding the endoscopically-assisted technique for removal of displaced gutta-percha using the sublabial antroscopy approach (Yura S, Ohga N, Ooi K, Izumiyama Y. Procedure of endoscopic removal of a gutta-percha point in maxillary sinus mucosa by ultrathin arthroscope.

    Two hundred and twenty-nine children aged 12-15 years who were continuous residents of Penang island, in the north of Peninsular Malaysia were examined for caries and enamel defects. Caries prevalence was 82.2% with a DMFT score of 3.4 and DMFS score of 4.9; there were very few missing teeth and very little untreated caries in the population examined. Majority of DF (decayed/filled) lesions were pits and fissures with approximal and smooth surfaces relatively caries free. The prevalence of enamel defects was 76.4% with 19.1% of all teeth examined being affected. More posterior than anterior teeth were affected by enamel defects just as there were more maxillary than mandibular teeth affected by enamel defects. Diffuse patchy opacities were the most common defect diagnosed and this was found in 60.2% of the population examined. A bilateral distribution of diffuse patchy opacities was seen in 41.5% of the population examined. Tooth surfaces with enamel defects were no more susceptible to caries than defect-free surfaces.
