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.

PMID: 3155001

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%.

Cross-infection control in Malaysian dental practice

Razak IA, Lind OP

Singapore Dent J, 1995 Jul;20(1):11-5.

PMID: 9582683

A questionnaire survey on cross-infection control was conducted among 1371 professionally trained dentists whose names appeared in the Malaysian Government Gazette of 1990. A 73.1 percent response rate was obtained. About 13 percent of the dentists routinely did not wear gloves during treatment of patients as opposed to 54 percent who routinely did. About 83 percent and 52 percent of dentists wore a mask and eyewear or glasses respectively when carrying out dental procedures. About 93 percent of dentists would use a new sterile needle for each patient and about 40 percent would wipe working surfaces with disinfectant after each patient. The practice of sterilizing handpieces was found to be uncommon as opposed to the sterilization of hand instruments. Variations were observed in some of the infection control measures by gender, seniority in service and employment status. More than one-third of the respondents had experienced puncture wounds during the last month prior to the survey.

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.

Management of an avulsed tooth with severe root resorption

Meon R

Singapore Dent J, 1988 Dec;13(1):53-6.

PMID: 3155008

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.

PMID: 2097727

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.

BACKGROUND: Application of principles of electrocautery for hemostasis dates back to prehistoric times. Its modern implementation in various fields of general and head and neck surgeries have been well documented. However its usage in minor oral surgical procedures has gained popularity only recently. Complications associated with electro-surgery in the dental field are relatively rare and there is insufficient literature on its management.

CASE REPORT: We present a case report on management of an electrosurgery induced osteonecrosis involving maxillary alveolus of left premolars.

DISCUSSION: Inadvertent contact of the electrosurgery tip on bone can result in necrosis making it necessary to remove the sequestrum and graft the defect. Platelet rich fibrin in combination with bone grafts have been well documented to provide successful periodontal regeneration.

CLINICAL IMPLICATIONS: Our aim of presenting this report is to create awareness among the health care providers regarding electrosurgical injuries. To our knowledge, this is the first time platelet rich fibrin has been used in the management of intraoral electrosurgical injury. Combining bone grafts with platelet rich fibrin is a good alternative as it can be done with relative ease and predictable outcome.

Fulltext Effect of ageing towards location and visibility of mental foramen on panoramic radiographs

Ngeow WC, Dionysius DD, Ishak H, Nambiar P

Singapore Dent J, 2010 Jun;31(1):15-9.

PMID: 23739252 DOI: 10.1016/S0377-5291(12)70004-4

Mental foramen is an opening of the mental canal onto the lateral surface of the mandible. In this pilot radiographical study, in Malay population the effects of ageing towards the location and visibility of the mental foramen were determined. Most of the mental foramina were found to be located inferior to the apex of the second premolar. Non-visibility of the foramen was greatly increased in patients aged 50 years and above (Pearson Chi-square; p = 0.00). This finding may provide a guide to dental surgeries in Malay patients of different age groups.

Adenomatoid odontogenic tumour: a case study with radiographic differential diagnostic considerations

Siar CH, Ong ST, Ng KH

Singapore Dent J, 1996 Jul;21(1):19-22.

PMID: 10597178

Adenomatoid odontogenic tumours (AOT) are benign, hamartomatous odontogenic lesions that not uncommonly mimic a dentigerous cyst radiographically. Such a case as found involving an unerupted left maxillary canine in a 19-year-old Chinese female is described. The differential diagnosis of some common odontogenic cysts and neoplasms occurring in Malaysians, that may present in a dentigerous relationship to an unerupted tooth is discussed. A brief review of the radiographic literature on AOT is also included.

The prevalence of post-extraction complications in an outpatient dental clinic in Kuala Lumpur Malaysia--a retrospective survey

Jaafar N, Nor GM

Singapore Dent J, 2000 Feb;23(1):24-8.

PMID: 11602946

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.

Trends in tooth loss due to caries and periodontal disease by tooth type

Jaafar N, Razak IA, Nor GM

Singapore Dent J, 1989 Dec;14(1):39-41.

PMID: 2487474

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.

Fulltext Cytotoxicity of accelerated white MTA and Malaysian white Portland cement on stem cells from human exfoliated deciduous teeth (SHED): An in vitro study

Singapore Dent J, 2012 Dec;33(1):19-23.

PMID: 23739319 DOI: 10.1016/j.sdj.2012.11.001

The aim of this study was to compare the cytotoxicity of accelerated-set white MTA (AWMTA) and accelerated-set Malaysian white PC (AMWPC) on stem cells from human exfoliated deciduous teeth (SHED). The test materials were introduced into paraffin wax moulds after mixing with calcium chloride dihydrate and sterile distilled water. Subsequently, the set cement specimens were sterilized, incubated in a prepared Dulbecco's modified Eagle medium (DMEM) for seven days. The biomarker CD166 was used for characterization of SHED using flow cytometry. The material extracts were diluted at five different concentrations and incubated for 72h with SHED. The cell viability was evaluated using Dimethylthiazol diphenyltetrazolium bromide (MTT) assay, and the data was analysed using Mann-Whitney test (P<0.05). The results showed that AWMTA revealed significantly greater cell viability at 25 and 12.5mg/ml concentrations (P<0.05). Concomitantly, AMWPC exhibited greater cell viability at concentrations <12.5mg/ml and the results were significant at 1.563mg/ml (P<0.05). Both materials demonstrated moderate cytotoxicity at 25mg/ml and slight cytotoxicity at 6.25 and 3.125mg/ml. At 1.563mg/ml, no cytotoxic activity was merely observed with AMWPC. In conclusion, AMWPC exhibited favourable and comparable cell viability to that of AWMTA, and has the potential to be used as an alternative and less costly material in dental applications.

Profile of periodontal conditions in selected West Malaysian adults

Rahimah AK

Singapore Dent J, 1994 Jan;19(1):4-7.

PMID: 9582675

To obtain the profile of periodontal conditions in West Malaysian adults, five small scale surveys were carried out on selected occupational adult groups, 20-54 years old, between 1987 to 1990. Periodontal assessment was made using the CPITN index. In all, 779 subjects were examined. Results indicated that only 16% of the adults examined had healthy gingivae. Bleeding of the gingivae was limited to the younger (20-24 years) age group. Calculus is highly prevalent in at least 65.5% of all the subjects examined. Periodontal pockets were limited to mostly shallow pockets and the risk of developing pockets increased with increasing age. Both navy personnel and factory workers showed a higher number of healthy sextants across all ages as compared to the other three occupational groups; viz., rubber tappers, villagers and government workers. The rubber tappers were the only group with deep pockets, with the prevalence ranging between 8 to 25%. Implications of the findings to the Malaysian dental delivery system are discussed.
