Oral Cancer Awareness of Tertiary Education Students and General Public in Singapore.

OBJECTIVES: Oral cancer confers high morbidity and mortality rates. Late diagnosis of oral cancer is linked to a lack of awareness of its existence and known risk factors. The purpose of this survey was to examine the knowledge and awareness of oral cancer amongst different groups in Singapore. METHODS: A self-administered questionnaire (including questions on awareness, risk factor knowledge, and health beliefs about oral cancer) was distributed to undergraduate students from the medical and dental schools and other faculties at the National University of Singapore, as well as the general public. RESULTS: A total of 470 responses were analysed. Both medical and dental students were almost universally aware of the disease and correctly identified recognised risk factors for oral cancers. Dental students had a significantly higher level of knowledge of chewing betel quid as a risk factor than medical students (98% vs 74%; P < .0001), although 1 in 10 dental students did not identify alcohol as a risk factor. In contrast, undergraduate students from other faculties were the least aware of oral cancer (62%). Within the general public, knowledge of the risk factors of oral cancer aside from smoking was low, with only 41% aware of viruses as a possible aetiology. However, the younger population group, aged 18 to 34 years old, in general had better knowledge of the risk factors of oral cancer compared with older participants. CONCLUSIONS: There is a general lack of awareness about oral cancer and its associated risk factors amongst certain cohorts of the Singapore population. There exists room for further targeted education.

Psychological profile of Chinese with cleft lip and palate deformities.

OBJECTIVE: To assess the psychological well-being of patients with cleft lip and palate (CLP). PATIENTS/SETTING: Ninety-four Chinese CLP subjects between 10 and 40 years of age were recruited from the Discipline of Oral and Maxillofacial Surgery, The University of Hong Kong, between June and December 2003. They were divided into two groups for comparison: adolescents (10-16 years old) and adults (17- 40 years old). A control group of 116 healthy non-CLP patients was also recruited during the same period. INTERVENTIONS: All CLP and non-CLP patients were asked to complete a set of four questionnaires to assess their psychological status. The questionnaires included the Social Avoidance and Distress Scale, the Satisfaction with Life Scale, the Culture-Free Self-Esteem Inventory, and the Chinese Miller Behavioral Style Scale. RESULTS: Chinese CLP patients exhibited levels of subjective well-being and social anxiety that were similar to the published levels of a group of British CLP patients. They also had significantly lower general and social self-esteem but higher parental self-esteem than the non-CLP control group. CONCLUSION: CLP patients were generally satisfied with life and did not exhibit more social anxiety than the non-CLP control group. They also had a good relationship with their parents. Gender and educational level had no influence on their psychological profile. However, these CLP patients had lower self-esteem than non-CLP patients.

The early psychological adjustment of cleft patients after maxillary distraction osteogenesis and conventional orthognathic surgery: a preliminary study.

PURPOSE: To compare the early psychological changes of cleft lip and palate (CLP) and noncleft patients after maxillofacial corrective surgery, including maxillary distraction osteogenesis and conventional orthognathic surgery. MATERIALS AND METHODS: Nine CLP patients were compared with a group of 9 non-CLP patients having similar dentofacial deformities in a prospective longitudinal cohort study. Five of the CLP patients underwent maxillary distraction osteogenesis and 4 underwent conventional orthognathic surgery. A control group of 9 noncleft patients received conventional orthognathic surgery. All patients completed a set of questionnaires to enable their psychological profile to be assessed. The data were collected immediately before surgery (T1), and at 3 weeks (T2) and 12 weeks (T3) after surgery. RESULTS: The CLP patients treated with distraction osteogenesis were happier, but had a higher level of social anxiety and distress than the CLP patients receiving conventional orthognathic surgery. On the other hand, the CLP patients overall were happier, with lower social anxiety and distress, than the noncleft control group. The CLP patients showed a higher level of parental self-esteem than the noncleft patients. CONCLUSION: This preliminary study shows that CLP patients were generally happier, and had a higher level of parental support, than normal patients suffering from dentofacial deformities. Maxillary distraction osteogenesis seemed to induce a higher level of anxiety and distress in CLP patients than conventional orthognathic surgery in both cleft and noncleft patients.
