[Training and interprofessional collaboration to improve oral care for older people]. / Training en samenwerking ter verbetering van mondzorg voor ouderen.

Collaboration between oral care providers, district nurses and/or carers and nurse practioners in primary care is necessary to improve the oral health of frail and care-dependent older people. On the one hand, this is important when the oral health of older people is at risk of deteriorating and support in daily oral hygiene care is needed. On the other hand, it makes it easier for district nurses and carers to consult the oral care provider when they identify oral health problems. In general, interprofessional care contributes to a better awareness of the importance of good oral health and oral care in older people. On-the-job training could be an effective method for training oral health care skills by care professionals. .

AAV2/1-TNFR:Fc gene delivery prevents periodontal disease progression.

Periodontal disease is a chronic inflammatory condition induced by tooth-associated microbial biofilms that induce a host immune response. Therapeutic control of progressive tissue destruction in high-risk patients is a significant challenge in therapy. Soluble protein delivery of antagonists to tumor necrosis factor-alpha (TNF-alpha) inhibits alveolar bone resorption due to periodontitis. However, protein therapy raises several concerns, such as recurrence of disease activity after treatment cessation and repeated dosing regimens. In this study, we used pseudotyped adeno-associated virus vector based on serotype 1 (AAV2/1) to deliver the TNF receptor-immunoglobulin Fc (TNFR:Fc) fusion gene to rats subjected to experimental Porphyromonas gingivalis (Pg)-lipopolysaccharide (LPS)-mediated bone loss. Animals received Pg-LPS delivered to the gingivae thrice weekly for 8 weeks, vehicle alone, Pg-LPS and intramuscular delivery of pseudotyped AAV2/1-TNFR:Fc vector (1 x 10(11) DNase I-resistant particles) or AAV2/1-TNFR:Fc vector delivered to naive animals. AAV2/1-TNFR:Fc therapy led to sustained therapeutic levels of serum TNFR protein and protected against Pg-LPS-mediated loss of bone volume and density. Furthermore, AAV2/1-TNFR:Fc administration reduced local levels of multiple proinflammatory cytokines and osteoclast-like cells at the periodontal lesions. These findings suggest that delivery of AAV2/1-TNFR:Fc may be a viable approach to modulate periodontal disease progression.

The prevention of oral complications in bone-marrow transplantations by means of oral hygiene and dental intervention.

Oral complications cause morbidity and mortality in patients, undergoing allogeneic or autologous bone-marrow transplantation. The clinical features and the pathogenesis of the oral sequelae of bone marrow ablative therapy and graft-versus-host disease are discussed. In addition, a preventive oral care procedure before, during and after bone-marrow transplantation is proposed.

[Prevention of oral side effects in children receiving chemotherapy]. / Cytostatica bij kinderen. Preventie van orale complicaties.

Especially in children the frequency of oral complications associated with cancer chemotherapy is high. The dentist plays an important role in preventing or reducing these sometimes life-threatening problems. Oral symptoms of the underlying disease, oral sequelae from chemotherapy, patient-related factors and a preventive oral care program will be discussed.
