    This is a retrospective study of 80 patients with major central and lateral middle third fractures of facial skeleton treated at University Hospital from 1981 to 1985. The most common was the fractures of zygomatic complex. The peak incidence was in the 20-29 year age group and males were involved more than females (ratio 9: 1). Road traffic accidents were to be blamed for most of the fractures which was 82.25%.

    The sugar content of twenty-four liquid medicines commonly prescribed for infants and young children were measured and the type of sugars present were also identified in four randomly selected samples. All the liquid medicines tested contained sugar, in the range of 29.4% to 61.2%. Sucrose appeared to be the most commonly used sugar. Whilst it is agreed that sucrose makes the medicine more acceptable to children, its continual use by the pharmaceutical industry should be discontinued due to its harmful effect on the dental health of children, particularly those taking these syrup-based medicines on prolonged basis. Sugar-free alternatives such as sorbitol or saccharin should be used instead.

    Delayed replantation of an avulsed tooth with an open apex resulted in failure of revascularization, necrosis of the pulp and extensive external root resorption. Removal of the necrotic pulp and repeated intra-canal dressings of calcium hydroxide over a three year period arrested the inflammatory resorptive process. The process was replaced by replacement resorption leading to ankylosis and infra-occlusion of the affected tooth. As the tooth was asymptomatic, it was retained in the arch to act as a space maintainer. To improve aesthetics, the crown was recontoured using a light-cured resin.

    A case of an incomplete tooth fracture followed by a complete fracture was presented. The difficulty of diagnosing this condition was discussed as well as the possible histological explanation of the symptoms experienced by the patient. It once again points out to practising dentists, that whilst deep pockets can give rise to severe periodontal pain, intense and excruciating pain should be investigated with the cracked tooth in mind.

    Early-onset periodontitis in children, teenagers and young adults is quite rare. This form of periodontitis progresses very rapidly and cause massive destruction to the periodontium. Various names have been given to this condition since it was first recognised in the 1920s. Through time the nomenclature changed from one to the other. Currently 3 forms of early-onset periodontitis are recognised--i.e. prepubertal periodontitis (PPP), localised juvenile periodontitis (LJP) and rapidly progressive periodontitis (RPP). The clinical features of juvenile periodontitis as it was first described together with that of the present 3 clinical entities mentioned above are presented. Concepts on the aetiology of the disease have also changed through time, and include degenerative process, bacterial infection, defects in the host defense system and heredity. Current thought is that there is an interplay of most of these factors in pathogenesis of the disease. Treatment modalities changed too. At the moment, comprehensive periodontal therapy with meticulous oral hygiene measures seem to be the treatment of choice. Concurrently, systemic tetracycline administration might have some added benefits.

    Granular cell ameloblastomas are uncommon lesions accounting for about 3-5% of all histologic subtypes of ameloblastoma. The plexiform granular cell odontogenic tumour, on the other hand, is a newly described lesion characterised by a monophasic plexiform pattern of granular cells. This article reports a tumour found occurring in the left mandible of a 67-year-old Indian male which histologically showed features of both the aforementioned lesions.

    A case of talon cusp in the primary maxillary left central incisor is reported. This dental anomaly was not associated with any other somatic or dental abnormality. Though pulpal extension into the cusp was detected radiographically, clinical examination after the cusp was ground failed to reveal any pulpal extension. The tooth was badly carious and was restored with a polycarbonate crown.

    Transposition of teeth is a rare and special type of ectopic eruption where two contiguous teeth are found occupying each other's respective normal positions. Nine patients with transposed maxillary teeth are reported. The literature on transpositions, especially on the theories regarding the aetiology, is reviewed.

    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.

    BACKGROUND: To quantify participation in dental research activities in Malaysia, and investigate its association with socio-demographic and professional characteristics, and perceptions of research and development (R&D) culture.

    MATERIALS AND METHODS: Dental academics in Malaysian dental schools were invited to complete a questionnaire by email and post. The survey comprised questions on research activities in the past 12 months, socio-demographic and professional characteristics, and the R&D Culture Index. Principal components factor analysis was carried out to confirm the factor structure of the R&D Culture Index. Chi-square test was used to identify association of research activities with R&D culture, and socio-demographic and professional characteristics. Binary logistic regression was carried to identify predicators of research activities.

    RESULTS: Of 256 potential participants contacted, 128 (50%) useable responses were returned. Three R&D Culture factors accounting for 57.4% of variance were extracted. More positive perception of R&D Support was associated with Malaysians (0.025) and those employed in Government schools (0.017). R&D Skills and Aptitude were associated with older respondents (0.050), PhD qualification (0.014) and more years in academia (0.014). R&D Intention was associated with any of the socio-demographic characteristics. Thirty (23.4%) respondents reported a peer-review research publication in the past 12 months, which was associated with having a PhD (OR 12.79, CI 1.28-127.96), after adjustment in regression analyses.

    DISCUSSION: Postgraduate research training should be encouraged to promote participation in research activities. R&D culture did not appear to impact on research productivity. Other factors such as individual attitudinal interests should be studied.

    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.
