Background and Aims:

The scope of this working group was to review: (1) the effect of professional mechanical plaque removal (PMPR) on secondary prevention of periodontitis; (2) the occurrence of gingival recessions and non-carious cervical lesions (NCCL) secondary to traumatic tooth brushing; (3) the management of hypersensitivity, through professionally and self administered agents and (4) the management of oral malodour, through mechanical and/or chemical agents.

Results and Conclusions:

Patients undergoing supportive periodontal therapy including PMPR showed mean tooth loss rates of 0.15 ± 0.14 teeth/year for 5-year follow-up and 0.09 ± 0.08 teeth/year (corresponding to a mean number of teeth lost ranging between 1.1 and 1.3) for 12–14 year follow-up. There is no direct evidence to confirm tooth brushing as the sole factor causing gingival recession or NCCLs. Similarly, there is no conclusive evidence from intervention studies regarding the impact of manual versus powered toothbrushes on development of gingival recession or NCCLs, or on the treatment of gingival recessions. Local and patient-related factors can be highly relevant in the development and progression of these lesions. Two modes of action are used in the treatment of dentine hypersensitivity: dentine tubule occlusion and/or modification or blocking of pulpal nerve response. Dentifrices containing arginine, calcium sodium phosphosilicate, stannous fluoride and strontium have shown an effect on pain reduction. Similarly, professionally applied prophylaxis pastes containing arginine and calcium sodium phosphosilicate have shown efficacy. There is currently evidence from short-term studies that tongue cleaning has an effect in reducing intra-oral halitosis caused by tongue coating. Similarly, mouthrinses and dentifrices with active ingredients based on Chlorhexidine, Cetylpyridinium chloride and Zinc combinations have a significant beneficial effect.
