Guideline for oral healthcare of adults with Huntington's disease Graham Manley1, Helen Lane1, Annette Carlsson2, Bitte Ahlborg2, Åsa Mårtensson2, Monica B Nilsson2, Sheila A Simpson3,4 & Daniela Rae*3,4; On behalf of the contributing members of the European Huntington's Disease Networks Standards of Care Dental Care Group A preventive dentistry regime should be implemented at the earliest possible opportunity and maintained throughout development of the condition. The use of high fluoride toothpaste is essential.
Discuss with dieticians their recommendations for use of highly cariogenic foods. Work closely with all professional and nonprofessional groups concerned with care of the person with Huntington's disease.
In the early stage of onset of the condition, consider carefully before providing advanced conservative treatment (i.e., crowns, bridges, implants). In the later stages, maintenance of complex restorative dentistry may present real problems for dentists and caregivers. This may be a difficult issue for patients and/or caregivers to accept will depend upon each individual clinical situation.
The use of intravenous conscious sedation is an extremely valuable tool for dentists when treating people in the mid and late stages of the condition. It may avoid complicated general anesthetic hospital admissions. In the case of a recurrent lip trauma from choreic mouth movements discuss with caregivers frequency and severity of event and options for prevention, using a mouth guard (if appropriate and safe) or extractions if necessary.
As a dentist with experience of treating people with Huntington's disease you must consider it an essential responsibility to become involved in training other colleagues.
Always assume (unless told or from experience) that the patient with Huntington's disease understands and can communicate. Respect his/her wishes even if they do not comply with what you as a dentist considers to be in the interest of good oral health. Summary These guidelines present an overall strategy for oral healthcare based on
the principles of achieving a disease-free, pain-free and safe mouth. The standards of care
referred to in the document seek to provide guidelines for the care and treatment that is no
less a standard provided for an individual that does not have this condition. Such care and
treatment will take into account the health and safety of each individual within the context
of their condition. Particular emphasis is placed on dental professionals working within a
multidisciplinary team, focusing on prevention of oral disease and providing treatment
appropriate to the various stages of the progression of this condition. It is intended that by
providing and subsequently promoting these guidelines, it will focus the dental professions
work on this condition and the implementation of good care for people with Huntington's
