The most important preventive and therapeutic effort to reduce inflammation is to remove the dental plaque thoroughly. Oral self-care is thus of crucial importance to achieve and maintain oral health. There is a scarcity of scientific evidence on the most effective models for behavioural change aimed to improve oral hygiene. There is a need for randomized-controlled trials, based on behavioural sciences and performed with great methodological rigour, to investigate the usefulness of these proposed behavioural changes. Oral hygiene regimens for patients with natural teeth as well as dental implants should include brushing twice daily, inter-dental cleaning once daily and rinsing with efficient rinses as an adjunct to mechanical infection control. Power toothbrushes are preferable as they are more effective than manual toothbrushes. Inter-dental brushes seem to be most effective and useful for inter-dental cleaning. Scaling and root planing is effective in reducing inflammation and probing depths in patients with periodontitis.
