Fighting the Fight for Healthy Teeth

It is known that teeth can protect themselves, to some extent, from attack by bacteria but that inflammation within a tooth can be damaging and, in extreme cases, lead to abscess or death of the tooth. New research published in BioMed Central’s open access journal BMC Immunology shows that odontoblast cells are part of the immune system and fight to protect teeth from decay.

Inside a tooth odontoblast cells sit between the enamel and pulp and produce a layer of dentin to protect the pulp from wear and infection. This research shows that, when under attack from bacteria, the odontoblast cells also orchestrate an immune response, producing antimicrobial peptides (β-defensins) to fight the infection directly, protein messengers (chemokines) which recruit white blood cells to the site of infection, and pro-inflammatory signalling proteins (IL-1β, IL-1α, and TNF-α) which, in turn, initiate an inflammatory response.

Missed Appointments Denying Others NHS Care, Warns BDA, UK

Patients failing to attend NHS dental appointments in England could be denying significant numbers of other people the chance to access care, according to a survey by the British Dental Association (BDA). The survey suggests that committed NHS dentists in England each lose the equivalent of almost two weeks a year because patients fail to turn up for appointments.

The BDA believes that the research highlights a problem of a significant scale and that the option to charge a fee for missed appointments, abolished as part of the widely-criticized 2006 reforms to dentistry, should be reinstated.
