Objective: To investigate patients' knowledge of the effects of smoking on periodontal health.
Design: Patient answered questionnaires, which were anonymous.
Setting: Patients who attended GKT Dental Institute, King's College, London for dental treatment.
Subjects: One thousand patients attending Restorative Consultant Clinics and Primary Dental Care.
Results: Seventy-eight per cent of patients were aware that smoking had a negative impact on health. However, 52% of these patients who were aware could not state what the negative effects were on oral health. Seven per cent of patients stated that smoking affected the gums but did not state how it affected the gums. Only 6% of respondents knew specifically of the link between smoking and periodontal disease. The only statistically significant factors associated with increased awareness were smoking status, ie being a non-smoker and being registered with a general dental practitioner. Non-smokers and those registered with GDPs were more likely to be aware of the association between smoking and periodontal diseases.
Conclusions: This study highlights patients' lack of awareness of the relationship between smoking and periodontal diseases, with only 6% of respondents knowing of the link between tobacco and periodontal diseases.
