1.  OS-1: Prevalence of Oral Lesions and Dentition Status among Non Smoking Diabetes Patients Attending HUSM Diabetic Clinic 
To determine the prevalence of oral mucosal lesions and dentition status among non smoking diabetes patients attending the Diabetic Clinic at Hospital Universiti Sains Malaysia (HUSM).
Patients and Method:
This cross sectional case-control study involved 300 diabetic case and 300 non-diabetic control subjects. Data was collected from November 2007 till March 2008. Demographic information, duration and type of diabetes, glycosylated hemoglobin values (HbAc), medical complications, history and current use of medication was obtained from medical records. Detail oral examination of the oral cavity was done based on international criteria and WHO codes. The number of remaining teeth and presence of dentures were also noted.
There were more females in cases (67.7%) and controls (57.7%). Mean age in both groups was comparable. A higher percentage of subjects were in the 40–59 years age group. Most had type II diabetes (94.3%). About 42.3% had diabetes within the last five years followed by 35.5% who had diabetes between 5–10 years duration and 22.3% had diabetes for more than ten years. Most diabetic subjects were on oral treatment (64.3%) and had poor metabolic control (41.7%). About 10.7% had some form of diabetes complications. The most prevalent oral lesions among diabetics were fissured tongue (29%), denture stomatitis (13.7%), geographic tongue (3.3%) and frictional keratosis (3.0%). About one third of subjects in both groups use dentures. Diabetics have significantly higher prevalence of geographic tongue (p=0.050) and denture stomatitis (p= 0.026). They have a lower mean number of remaining teeth compared to non-diabetics (p<0.001).
Discussion and Conclusion:
Having less mean number of remaining teeth and a higher prevalence of oral lesions among diabetics is a worrying outcome. Thus diabetic patients need intensive dental care and attention to minimize the disease burden.

2.  PS-01: Associated Factors of Tooth Wear among 16-Year-Old Secondary School Children in Kota Bharu Kelantan 
Tooth wear is a common finding in oral examinations. Pathological tooth wear (PTW) is the amount of wear that exceeds the normal phenomena of ageing or the normal threshold value of wear. The objective of this study was to determine the associated factors of PTW among 16-year-old secondary school children.
This case-control study involved 576 participants randomly selected from eight government secondary schools. The Smith and Knight Tooth Wear Index and WHO criteria were used for charting of tooth wear and dental caries respectively. Data were analyzed using a simplified Microsoft Excel program developed based on the index, to quantify PTW. Controls were subjects with no PTW indicated by zero scores on all tooth surfaces. Cases were subjects with PTW having at least one surface scoring 1 for tooth wear. Consequently, responses were obtained from self-administered questionnaire containing socio-demographic profile of the family, general questions, oral hygiene and food and drinks practices and other associated variables for tooth wear, which was previously developed based on expert opinions.
About 40% and 57% were males were in controls and cases respectively. On performing multivariable analysis, sex, monthly household income, carbonated drinks, duration of intake of orange juices, caries experience and swimming were significantly associated with PTW.
In conclusion the factors associated with PTW were no different from those encountered in Western societies. Realizing that some significant variables were modifiable, oral health promotion should emphasize on this information. The erosive potential of some foods and drinks require further investigation.
