Is age a risk factor for Periodontitis?
Prevalence and severity of chronic periodontal disease increases with age.
Greater periodontal destruction in the elderly reflects lifetime disease accumulation rather than an age-specific condition.

‘Attachment gains were low, however, compared with other studies, both in the SDD and the placebo groups. Anecdotally, we feel this is because of the fact that most of the elderly patients in this study demonstrated significant recession and the majority of clinical improvements observed resulted from gingival shrinkage (leading to shallower pockets and increased recession), rather than gains of clinical attachment.’

Does age impact on periodontal treatment outcome?
Age is not a significant factor for the outcome of periodontal therapy
Periodontal disease progression can be prevented or markedly arrested
Gingival recession post-therapy is common Maintenance, supportive care is essential

Periodontitis and systemic disease
100 million bacteria in one pocket related to one surface of one tooth
Frequent transient bacteraemias occur in patients with periodontal infections
increase in intensity of bacteraemias correlates with the extent and severity of periodontitis

Summary of findings Plausability
Periodontitis leads to bacteraemia, activating the host inflammatory response which favours atheroma formation
Intervention Moderate evidence that periodontal treatment reduces serum
CRP levels and improves markers of endothelial function; limited evidence for improvement in coagulation; no effect on lipid profiles

Intervention Moderate evidence that periodontal treatment reduces serum

Epidemiology There is strong and consistent epidemiologic evidence that
periodontitis imparts increased risk for future cardiovascular disease; particularly in males and in younger individuals. Risk for stroke is greater than for CVD.

aspiration pneumonia from anaerobic organisms usually occurs in patients with periodontal disease.

Effects of periodontal treatmenton lung function andexacerbation frequency inpatients with chronic obstructivepulmonary disease and chronicperiodontitis: A 2-year pilotrandomized controlled trialZhou X, Han J, Liu Z, Song Y, Wang Z, Sun Z. Effects of periodontal treatmenton lung function and exacerbation frequency in patients with chronic obstructivepulmonary disease and chronic periodontitis: A 2-year pilot randomized controlledtrial. J Clin Periodontol 2014; 41: 564–572. doi: 10.1111/jcpe.12247.
AbstractAim: To evaluate the direct effects of periodontal therapy in Chronic ObstructivePulmonary Disease (COPD) patients with chronic periodontitis (CP).Materials and Methods: In a pilot randomized controlled trial, 60 COPD patientswith CP were randomly assigned to receive scaling and root planing (SRP) treat-ment, supragingival scaling treatment, or oral hygiene instructions only with noperiodontal treatment. We evaluated their periodontal indexes, respiratory func-tion, and COPD exacerbations at baseline, 6 months, 1, and 2 years.Results: Compared wit h the control group, measurements of periodontal indexeswere significantly improved in patients in two treatment groups at 6-month, 1-year,and 2-year follow-up (all p < 0.05). Overall, the means of forced expiratory volume inthe first second/forced vital capacity (FEV1/FVC) and FEV1 were significantly higherin the two therapy groups compared with the control group during the follow-up(p < 0.05). In addition, the frequencies of COPD exacerbation were significantly lowerin the two therapy groups than in the control group at 2-year follow-up (p < 0.05).Conclusions: Our preliminary results from this pilot trial suggest that periodontaltherapy in COPD patients with CP may improve lung function and decrease thefrequency of COPD exacerbation.

Dental plaque: potential source of airway colonisation in cystic fibrosis• P. aeruginosa, not a normal component of the oral
bacterial community, was isolated from subgingival plaque of CF patients positive for Pseudomonas lung infection.
• Pseudomonas spp. in plaque may be a potential source for reinfection of the lung, following successful eradication therapy.
• Regular removal of dental plaque, in the early stages of Pseudomonas lung infection may minimise potential reinfection of the lung from the oral cavity.

Periodontal disease and respiratory disease
patients with poor oral hygiene levels had an increased risk of developing COPD
patients with COPD had more periodontal attachment loss than healthy controls
improving oral hygiene significantly reduced the occurrence of respiratory disease
evidence of an association between oral health and both pneumonia and COPD, with the evidence for the link to pneumonia being stronger
