    Quality radiographs of diagnostic value are important in root canal treatment. The dentist who has knowledge and skills in the use of radiographs for diagnostic purposes has a professional responsibility to ensure that the radiographs are obtained with minimum risk of radiation dose to and for the benefit of the patient. This article reviews the effectiveness of radiography techniques required for successful root canal treatment with the patient’s interest in mind. Awareness of effectual radiographic techniques, their constraints and applicable techniques for improvements are discussed. It seeks to reduce potentially harmful ionising radiation dose to patients and optimise the use of X-rays to produce diagnostic radiographs during root canal treatment.

    An audit of broken/lost removable appliances was carried out. This study aimed to measure the occurrence of broken/lost appliances over a period of 6 months. It also assessed whether there was any difference in the occurrence rate between patients who paid for treatment and those who received it free of charge. The results indicated that the total number of broken/lost removable appliances was 183, from a total of 472 appliances issued. For paying patients, 59 of 177 patients had at least one broken/lost appliance, giving an occurrence rate of 33.3%. For nonpaying patients, 60 of 112 patients had at least one broken/lost appliance, giving an occurrence rate of 53.6%.

    The objective of this study is to report the occurrence, demographic and clinical findings of lip mucoceles in children. A restrospective study was conducted at the paediatric dental clinic situated at Hospital Sultanah Aminah, Johor Bahru. The period of study was 3 years beginning 2003 to 2005. Out of 1407 new cases seen over the period of study 17 (1.2%) patients presented with lip mucoceles. All lesions occurred in the lower lip. There was no sex or racial predilection. The average duration of the lesion prior to seeking treatment was 2.8 ± 2.8 months. Most patients (76.5%) first saw a medical practitioner for the problem. No spontaneous resolution of the lesions in any of the patients was noted. The preferred method of treatment of lower lip mucoceles in children is surgical excision of the involved minor salivary glands. Salivary gland mucoceles in children predominantly involve the lower lip and can be treated successfully by complete removal of the involved and associated minor salivary glands.

    There are evidences that chronic oral infections are associated with cardiovascular disease (CVD). Periodontal disease is a common, mixed oral infection affecting the supporting structures around the teeth. It was reported that 75% of the adult population has gingivitis and 20% to 30% exhibits the severe destructive form of periodontitis. Although more than 500 bacterial species inhabit the human oral cavity, only a few Gram negative bacteria such as Prevotella intermedia, Fusobacterium nucleatum, Porphyromonas gingivalis, Tannerella forsythensis, Treponema denticola and Actinobacillus actinomycetamcomitans causes gingivitis and periodontitis. These periodontal pathogen occupy the subgingival space and organize as a bacterial biofilm. The bacterial biofilm will be in direct contact with host tissues along an ulcerated epithelial interface, called periodontal pocket. The break in the epithelial integrity directly exposes the host to bacteria and their products eg. lipopolysaccharide (LPS) endotoxin. (Copied from article).

    This case report presents a combined surgical – orthodontic approach to the management of an unerupted maxillary right permanent central incisor in a 13 year-old Chinese male. Radiographic investigations revealed that the tooth was severely dilacerated, most likely as a result of trauma sustained to the upper maxillary right deciduous central incisor at the age of 3 years. After securing adequate space for the unerupted tooth by fixed appliance therapy, surgical exposure of the crown was carried out under local anaesthesia and oral sedation.
    A gold chain was bonded to the exposed crown of the tooth. Traction was then carried out and the tooth was successfully brought to its final and correct position in the arch after 36 months of active orthodontic treatment.

    The aim of the study was to assess the potential role of dentists as smoking cessation counsellors in their practice. The target group comprised of all public and private sector dentists in the Federal Territory of Kuala Lumpur (FTKL) and Selangor. Data were collected via a twenty-six item questionnaire which was mailed to 831 dentists. A response rate of 67.1% was obtained. Results revealed that the majority of the respondents (97.8%) perceived that in addition to providing oral care, dentists should also be interested in their patients’ general health. Generally, about two-thirds of dentists (69.1%) and especially those from the public sector (76.4%) considered that they have an important role to play as smoking cessation counsellors. However, less than half of the respondents (40.3%) perceived that patients do not expect smoking cessation advice from their dentists. Yet, more than half of the respondents (55.1%) provided advice or helpful hints in order to motivate their patients to quit smoking. About 65% of the overall respondents did explain to their patients regarding the health risk due to smoking and its detrimental effects. Perceived obstacles to smoking cessation include lack of information between dentistry and smoking cessation (86.1%) followed by lack of training and lack of time.

    Squamous cell carcinoma (SCC) is the commonest cancer in the mouth. Multiple risk factors, such as smoking, alcohol consumption, irradiation, viruses infection and chronic irritation are thought to be responsible for the formation of oral squamous cell carcinoma. Although SCC can develop through a series of precancerous stages manifested as various degrees of epithelial dysplasia, this is not always the case. p53 is the commonest mutated gene in human cancers. Mis-sense mutation of the gene or complexing of the protein with viral or cellular proteins prolongs its half-life and leads to its detection by immunohistochemistry. This study was designed with the aim of demonstrating any possible relationship between p53 and oral squamous cell carcinoma by immunohistochemical staining techniques. A total of 66 specimens from the oral cavity (10 normal mucosa, 11 hyperkeratosis without dysplasia, 11 mild dysplasia, 11 moderate dysplasia, 10 severe dysplasia and 13 SCC) were examined for the presence of p53. The results show p53 was not expressed in normal mucosa, but was found with increasing frequency in increasingly severe dysplasia and SCC. In conclusion, this study shows p53 mutation is common in oral squamous cell carcinoma and probably occurs early in the multisteps of oral carcinogenesis.

    A review of incident oral and maxillofacial biopsies in Kelantan from January 1994 to December 1998 was carried out to evaluate the scope of pathological lesions managed by the two main oral and maxillofacial units in this state. A total of 357 biopsy reports from incident cases of pathological lesions were reviewed. The biopsies were mainly from intra-oral sites (n=326, 91.3%). Females had more frequent oro-facial lesions compared with males (male:female ratio is 0.8:1). The Bumiputera ethnic group had the most number of biopsies (n=321; 90%). The three most commonly observed histopathological groups were the connective tissue hyperplasia (n=90; 25.2%), epithelial dysplasia and neoplasia (n=68; 19%) and salivary gland cysts/mucocele (n=56; 15.7%). The top five most frequent diagnoses were mucocele (n=56; 15.7%), squamous cell carcinoma (n=45; 12.6%), epulides (n=31; 8.7%), pyogenic granuloma (n=25; 7.0%) and fibroepithelial polyp (n=19; 5.3%). Oro-facial malignancies made up almost one-fifth of all diagnoses and squamous cell carcinoma was the most common sub-type. Lymphomas in the oro-facial region (n=8; 11.4%) were more common than basal cell carcinoma (n=7; 10%) and salivary gland malignancies (n=6; 8.5%). Epithelial jaw cysts consisted of 8.7% (n=31) of all diagnoses, where inflammatory types were more common than the developmental types. Odontogenic tumours consisted of 5.6% (n=20) of all diagnoses and ameloblastoma was the predominant type.

    The tooth provides a non-shedding surface ideal for microbial and plaque accumulation. Despite being exposed to regular environmental perturbations, the microbial composition and proportions in the plaque often remains in homeostasis and is relatively stable over time. Supragingival plaque sampled from various sites on the tooth surface was pooled and conventionally analyzed for its microbial constituent. Classification of microbial isolates was made based on the characteristics exhibited by the growth colonies, Gram-stained cells, as well as biochemical reactions using the API Identification System kit. Observation was also made of the colony forming units on both non-selective and selective agar culture plates. A variety of bacteria, both of the facultative and anaerobic types, were isolated from the supragingival plaque of the Malaysian population. Among those found to predominate the supragingival plaque include the Gram positive and Gram negative cocci and rods from the genera Streptococcus, Staphylococcus, Actinomyces, Fusobacterium, Corynebacterium, Clostridium, Bacteroides, Veilonella and Lactobacillus. In addition, yeast within the genus Candida was also isolated from the plaque samples.

    The objective of this survey was to understand the current trend of readership of professional dental journals among Malaysian dentists. A total of 225 questionnaires were sent out to Malaysian dentists who attended various dental related conferences throughout Peninsular Malaysia from February 2006 to July 2006. Questionnaires comprised of questions relating to dentists’ socio-demographic status and a list of journal(s) read by them. Malaysian dentists’ view on the content and quality of a particular dental journal, i.e. the Malaysian Dental Journal (MDJ) was also enquired. The details of this finding are highlighted in Part II of this study. A total of 156 questionnaires were returned; the respondents were made up of 61 male and 91 female dentists. Almost 80% of the respondents aged between 20-49 year-old and most respondents (n= 132; 84.62%) only had a basic Bachelor of Dental Surgery or equivalent degree while another 19 (12.18%) had in addition, a post-graduate degree. Almost equal numbers of respondents were working in the Ministry of Health (MOH) or Armed Force (n=73; 46.8%) and private practice (n=74; 47.4%). Also, equal number of respondents (n=67; 42.95%) were found to be working as single-handed practitioner and in a partnership/assistant/working-with-other specialties type of practice Almost two-thirds (n=103; 66%) of the respondents read more than one professional journal, and a majority of them worked in the private sector. The percentage of readers reading more than one journal from the private practice (n=67, 60.0%) was close to twice of that from the MOH (n=36, 35.0%). No specific age-group pattern was present but the least number of subscribers were from those 60 year-old and above (n=3), whereby none of them subscribed to any professional dental journal/magazine. The highest percentage of subscribers were from those in the age group of 40-49 year-old, whereby 86.49% (n=32) of dentists in this age-group subscribed to at least one professional dental journal/magazine. Out of the list of journals/magazines provided, it was found that the MDJ has the most number of readers. The MDJ was most read by dentists in the private practice while the Annals of Dentistry of the University of Malaya was most read by dentists in the MOH. In conclusion, it was found that almost two-third of the respondents read more than one professional journal, with the MDJ receiving the most number of readers. More dentists in the private practice read professional dental journals than dentists in the MOH.

    The objective of this part of the study was to understand the current trend on readership of the Malaysian Dental Journal (MDJ) among Malaysian dentists. Their views on the contents and quality of the Malaysian Dental Journal were enquired. We also enquired the reasons they chose-to/chose-not-to read the MDJ. Of the 225 dentists surveyed, the number of MDJ readers was 101; with only 24.75% reading all issues published. The editorial section was rated as “useful” by 70.3% of readers, while 79.2%, 87.1%, 87.1% and 80.2% of readers rated the research article section, the review article section, the case reports section and book recommendation section similarly respectively. Feedback from readers indicated that they wanted more case reports, more review articles on “how to do it” and on medical problems in dentistry. More than half (55.45%) of the MDJ readers preferred to receive the journal in both hard and soft copies. For the non-readers, the most common reasons cited for not reading the MDJ was not being able to access to the journal, followed by not having time to read. Our finding suggested that the respondents preferred to learn from colleagues’ experience and to read article that can improve their clinical knowledge and skill.

    Introduction: There is generally inconsistent appropriate orthodontic referral among local dentists. Orthodontic indices are not routinely used to assess the need for treatment. The aim of this pilot study is to evaluate the efficacy of the Index of Orthodontic Treatment Need (IOTN) as an educational tool to improve their ability to assess orthodontic treatment need.

    Methodology: Local dental officers assessed 30 study models on two occasions (before and after IOTN training) and their findings compared with an expert group for agreement in IOTN scores and referral decisions. Training comprised oral/visual presentation, instruction manuals, ‘hands-on’ and self-study. Kappa statistic (?) was used to assess agreement.

    Results: As a group there was no significant improvement in referral decisions after training with only ‘moderate’ agreement (?=0.47), although half of the subjects improved. Agreement was better with aesthetic (?=0.51) than functional (?=0.41) assessment. ‘Sensitivity’ was 82.4% and ‘Specificity’ was 58.2% but both were not statistically significant before and after training.

    Conclusion: The IOTN has potential as an educational tool for improving the diagnostic skills of dental officers. More accurate assessment of the Dental Health Component with the IOTN ruler and familiarity with the Aesthetic Component has to be emphasized in future training.

    Deviations from normal occlusion are known as malocclusion. Orthodontics treatment usually is the choice of management of irregularities and abnormalities of their relation to the surrounding structures i.e malocclusions. Patient or parent commonly seeks orthodontic treatment for aesthetic reasons rather than functional problems such as temporomandibular joint dysfunction. With greater demand for orthodontic treatment due to greater awareness of the people towards dental health, good orthodontic treatment outcome would be expected. Good orthodontic treatment outcome usually related to good clinical management of the patients. (Copied from article).

    Gingival overgrowth (gingival hyperplasia, gingival fibromatosis) can be caused by underlying factors such as taking certain medications or genetic in origin. The extent of the enlargement varies in different individuals and also within the same individuals. Aesthetics and effective plaque control is compromised and part of the objectives of treatment is to help in these aspects. (Copied from article).

    The aim of the present study was to assess the current approaches and philosophies pertaining to direct restorations, bleaching and root canal treatment amongst general dental practitioners (GDPs) in the Klang Valley, Malaysia. A questionnaire, together with a stamped addressed envelope and an explanatory letter, was sent to 200 GDPs in the Klang Valley in April-July 2005. The GDPs were selected at random. A total of 153 (76.5%) of the GDPs responded to the survey. 46.4% of the respondents stated that the use of amalgam was decreasing whereas 79.7% stated an increase in the use of composite resins. Clinical indication (85.6%) and patients’ demand for aesthetics (73.9%) appeared to be the main factors influencing the choice of restorative materials. Fractured restorations was the main reason for the replacement of amalgam restorations (77.1%) whilst secondary caries was the main reason for the replacement of composite resin restorations (73.9%). Almost two thirds of the GDPs surveyed provided chair side bleaching while 75.8% of the GDPs would supervise home bleaching. Sodium hypochlorite was the most common endodontic irrigant used amongst the GDPs surveyed and cold lateral compaction was the most commonly used obturation technique.

    Objectives: The objectives of the study were to assess: i) the staining susceptibility of composite resins, ii) the ability of whitening toothpastes in removing stains from composite resins.
    Materials and Methods: Thirty specimens from each composite resins: Filtek Z350 (3M ESPE), Filtek Z250 (3M ESPE) and Beautifil (Shofu Inc.) were fabricated. After polishing, specimens were immersed in coffee for 3 days. Specimens were then brushed twice a day for 2 weeks using Colgate Total (Colgate-Palmolive, control group), Colgate Advanced Whitening (Colgate- Palmolive, test group) and Darlie All Shiny White (Hawley & Hazel Chemical Co., test group). Colour changes (?E*) were measured using Spectrophotometer at baseline, after coffee immersion and after brushing. Results were statistically analyzed using one way ANOVA and Tukey’s test.
    Results: There was significant difference in terms of colour changes for Filtek Z350, Filtek Z250 and Beautifil after coffee immersion (P0.05).
    Conclusions: Filtek Z350 was able to resist staining by coffee better than Filtek Z250 and Beautifil. The whitening toothpastes did not offer added advantage in terms of ability to remove stains compared to ordinary toothpaste.

    Radiology is important in the diagnostic assessment, treatment and monitoring progress of patients having dental and maxillofacial diseases. The central question in dental radiology is whether there is any risk with regard to low doses of radiation and what are the necessary protection needed to prevent any hazardous outcome with X-raying. With the emergence of the new millennium, major changes are happening in the field of science and technology. More efficient equipments are being discovered and more researches are being conducted to elicit better understanding of the radiation process and its effect on the human health. This article will review the latest guidelines for proper radiographic practice from the USA and Europe. It will address topics like the risks from dental radiography, selection criteria, protection for patients and staff, improvement to X-ray equipments, room dimensions and lead lining requirements. We have limited our research to intraoral, panoramic and cephalometric radiographs because these are the radiographs or images that are commonly taken in the general practice setting.
