    Oral cancer is the sixth most common malignancy in the world. Despite recent advances in cancer diagnoses and therapies, the five-year survival rate of oral cancer patients has remained at a dismal 50% in the last few decades. Oral cancer is of major concern in Southeast Asia primarily because of the prevalent oral habits namely betel quid chewing, smoking and alcohol consumption. This paper provides a brief overview on the various aetiological agents and risk factors implicated in the development of oral cancer.

    A retrospective study was carried out to review the records of 47 patients who had had in total 80 supernumerary teeth (ST) removed under general anaesthesia between 1975 and 2002. Malays made up 38.30%, Chinese 51.06%, and Indians 10.64% of the patients. The predominant age group was 6-10 year-old. The mean age was 12.96 ± 9.49 years. The male and female ratio was 1.35:1. Most of the patients had either one ST (n=31; 65.96%) or two ST (n=11; 23.40%). Five cases of multiple supernumeraries were recorded. Two patients experienced late formation of subsequent ST after the first surgery, thus requiring a second surgery. The majority of ST were conical in shape (n=35; 43.75%). Most of the ST were located in the premaxilla (n=55; 68.8%). Almost a quarter (23.75%) of ST were inclined towards the oral cavity. Some of the effects on the dentition were diastema, cystic changes, rotation, displacement, and retention of the permanent teeth and these were the indications for removal of ST. The most common surgical approach for maxillary ST was from the labial, buccal or labio-buccal approach.

    The aim was to examine the protein profiles of whole and parotid saliva using Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) and MALDI-TOF mass spectrometry. The banding patterns of proteins exhibited by the unstimulated whole saliva samples on the gel remained quite constant but the intensity of the protein bands were slightly different from one sample to another. Comparison of the protein profiles of unstimulated whole saliva and stimulated parotid saliva showed almost similar banding pattern. The exception is the presence of a pink protein band in the 65-67 kD region in the stimulated parotid saliva samples which was also observed in the unstimulated whole saliva sample contributed by a cerebral palsy patient. Analysis of the saliva samples using MALDI-TOF mass spectrometry also revealed that the stimulated parotid saliva samples exhibited some peaks that were in the same region as those for the unstimulated whole saliva sample of the cerebral palsy subject. This may imply that there is ineffective control of the parotid secretion in cerebral palsy subject under unstimulated condition. The SDS-PAGE and MALDI-TOF analyses may provide more information on the profiles of the salivary proteins which could be beneficial in the diagnosis of salivary gland dysfunction.

    Thirty extracted mandibular premolars were randomly divided into 3 groups. Canals were cleaned, obturated and the teeth incubated. Guttapercha removal was performed using: Hedström files with xylene (Group 1); ProFile® alone (Group 2) and combination of both (Group 3). Time required to remove the gutta-percha was recorded. Postoperative radiographs were taken. Specimens were split longitudinally and photographed. Amount of gutta-percha left at coronal, middle and apical thirds was calculated by computer (QWIN software) and the photographs were also evaluated visually by two endodontists. Results showed that the combined technique was fastest in removing gutta-percha. Radiographically, more residual was left in Group 2. Although computer analysis also showed more residual was left in Group 2, they were in a small percentage and there were no significant differences (P>0.05, SPSS paired-samples T test) among groups. Although there were significant differences between the two evaluators in their scoring, both generally agreed (Kappa’s analysis= 0.64) there was more guttapercha residual in Group 2 compared to Group 3 in the apical thirds. Although the differences in efficacy of guttapercha removal among these techniques were not significant, the use of ProFile® increased the speed of the procedure. The combined technique showed the most superior efficacy in gutta-percha removal.

    The objective of this study was to determine the effect of chewing commercially available meswak may have on levels of calcium, chloride, phosphate and thiocyanate in stimulated whole saliva. A total of 20 subjects participated in the investigation. They were distributed into two groups. Those in group A (10 individuals) were asked to first chew on a cotton roll (sized #1) followed by the chewing of an equivalent sized 5mm piece of commercially available meswak. Subjects in group B (10 individuals) did the same but, chewed on cotton roll (sized #2) followed by the chewing of an equivalent sized 10mm piece of commercially available meswak. After following a specified chewing protocol, samples of stimulated whole saliva were collected into a graduated tube at the end of every chewing regime. Calcium, chloride, phosphate and thiocyanate analysis were carried out using colour titration and spectrophotometer. Results from this investigation indicated that commercially available meswak chewing sticks apart from containing high amounts of calcium and chloride may possibly release phosphate and thiocyanate into whole saliva. These findings suggest that the commercially available meswak used as chewing sticks may have the potential of releasing substances into saliva that could influence the state of oral health. Further studies have to be carried out to ascertain the therapeutic benefits of chewing commercially available meswak.

    The aim of the study was to assess the association between past fluoride exposures from ingested toothpaste and current fluorosis manifestations in 10- 11 year old index subjects. Fluorosis was assessed with the Dean’s Index in 1343 10-11 year old index subjects. Two hundred index subjects who had younger 4-5 year old siblings were sub sampled and fluoride exposures from ingested toothpaste in their younger siblings (proxy subjects) were determined. The values for the fluoride ingested per brushing of the proxy subjects were utilised together with past frequency of toothbrushing of index subjects to extrapolate on the past exposure of index subjects. The mean extrapolated past fluoride exposure from ingestion of toothpaste was highly variable; 671.7 ug ± 739.3 ug (sem= 56.9). It was higher in the subjects with fluorosis (697.3 ug) than in those without fluorosis (646.89 ug) but differences were not of statistical significance. This approach of extrapolation has not been reported elsewhere and need to be validated. The implications of the present methodology to estimate past fluoride exposure is discussed.

    The standard procedure for alveolar cleft closure in cleft lip and palate patients is by alveolar bone grafting (ABG) where the residual opening of oronasal fistula in the palate is also closed simultaneously. Occasionally there is a situation of soft tissue inadequacy and attempt to close the fistula at the same procedure as ABG may compromise the result of the bone graft itself. An unforeseen leakage at the closure may cause graft infection leading to failure. This article reports on a technique where alveolar bone grafting was done without closure of residual palatal fistula to provide adequate soft tissue coverage for the grafted bone. This may reduce the risk of leakage at the oral mucosal coverage of the graft . The residual palatal fistula will be closed at later stage by muco-palatal flap or tongue flap. We reported on a case of a failed ABG which was reconstructed using this technique. Various other techniques to ensure success of ABG were also discussed. Conclusion: The alveolar bone grafting without closure of oro-nasal fistula reduced the risk of failure of ABG in a wide alveolar cleft.

    Missing teeth can be due to hypodontia, trauma or extraction. In general, the options for treatment depend on the severity of the hypodontia and the severity of the malocclusion. Occasionally, the space from missing teeth has to be maintained for prosthetic replacement and require an orthodontic/restorative approach. It is very important to ensure the space maintained is adequate for aesthetic reason so that it can be replaced with a prosthesis after the orthodontic treatment is completed. This article discusses a new innovation and clinical technique for maintaining this space during orthodontic treatment by using an acrylic tooth with several modifications. This innovation will be illustrated using two cases.

    Choosing the right light-curing unit can be a very difficult task for some orthodontists. Currently, there are various types of light curing units available in the market with various trade names and specifications. Most of the time information regarding light curing units is obtained from advertisements, websites or manufacturers’ catalogues. Sometimes such information can be misleading. This article attempts to provide several tips for orthodontists in selecting light curing units.

    A study was undertaken to identify the oral health status and treatment needs of 403 drug abusers enrolled in a drug rehabilitation center in Perak, Malaysia. The prevalence of dental caries was 97.0%. Calculus was present in 82.1% of the dentate individuals, but only 14.6% had pockets greater than 3mm. The mean DMFT observed was 11.7, with missing teeth (MT=9.6) constituting the major component. Denture needs were high (67.2%), but only 11.4% of individuals had prostheses.
