Prevention and oral hygiene: Instructions, toothbrush and mouthwash

Research output: PhD ThesisPhD-Thesis - Research and graduation internal

Abstract

The purpose of this thesis was to investigate aspects of periodontal disease prevention through the assessment of oral hygiene instructions, toothbrushes and mouthwashes. The websites of 35% professional dental care associations provided advice and/or information on toothbrushing without consensus and significant heterogeneity. All professional dental care associations recommended twice daily brushing with a manual toothbrush and fluoride toothpaste. With respect to other recommendations on oral self-care, there appears to be a need for alignment. Changes in daily oral hygiene behavior after the initial phase of Non-Surgical Periodontal Therapy based on the Oral Hygiene Behaviour questionnaire showed an increase in brushing time and the use of powered toothbrush, woodsticks, and interdental brushes. Based on single brushing exercises the powered toothbrush is more effective than the manual toothbrush with respect to plaque reduction. When a Chlorhexidine mouthwash is recommended, it can be used in combination with an sodium lauryl sulphate dentifrice without any interference regarding its inhibiting effect on dental plaque, regardless of the order of use. Also sodium fluoride and Chlorhexidine may be simultaneously be present in the same mouthwash without reducing Chlorhexidine efficacy with respect to plaque and gingivitis scores. All the findings from this thesis are directly applicable to the daily practice of Dental Care Professionals, and adherence will help to provide ‘evidence-based’ advice.
