Abstract There is no information on the misunderstanding of dental scaling; on whether the misunderstanding affects the general public to go for scaling or not; on complaints about dental scaling and suggestion of who should educate the public in the existing literature. This study gives the information from the general public in Hong Kong. METHODS: A cross-sectional survey by telephone interview on a random sample of 1412 subjects aged 13 years and above in Hong Kong was conducted from 3rd January to 15th February 2006. RESULTS: More females had received scaling (adjusted OR = 1.73, 95%CI 1.31-2.29 P < 0.001), 51-60 years age group had the highest scaling experience (adjusted OR = 2.69, 95% CI 1.55-4.68, P < 0.001). Higher education was related to scaling experience (P < 0.001). Of the subjects with complete data, 22.5% (307/1364) had never received dental scaling, 17.9% (55/307) did not understand the purpose, 12.1% (37/307) replied that it would make the teeth thinner, 11.4% (35/307) replied that the gum space would become wider, and 11.4% (35/307) stated that scaling would damage the gum. In all, 45.9% (298/649) of the subject reported bleeding, 33.7% (139/413) sensitivity, 40.5% (62/153) smaller teeth and 23.9% (84/351) widened gum space because of mistakes made during the procedure; 8.6% (56/649) of those who experienced bleeding, 17.8% (27/152) of those who reported the teeth became smaller and 12% (42/350) of those who stated that the gum space became wider intended to reduce the frequency, delay or not go for scaling. A total of 79.6% (841/1057) experienced one of the perceived problems; 27.8% (234/841) had complained about scaling. CONCLUSION: This study shows a common lack of knowledge of dental scaling in the Hong Kong population. Patients should be better informed about the aim before the procedure.

whether the misunderstanding affects the general public to go for
scaling or not; on complaints about dental scaling and suggestion of who
should educate the public in the existing literature. This study gives the

from 3rd January to 15th February 2006.
RESULTS:
More females had received scaling (adjusted OR = 1.73, 95%CI 1.31-2.29
P < 0.001), 51-60 years age group had the highest scaling experience
(adjusted OR = 2.69, 95% CI 1.55-4.68, P < 0.001). Higher education was
